I have a remoteobject class that handles all interactive with my remote data service. each time a call is made the dataservice checks that the user has a valid session. if they don't it won't run the requested method and it returns a fail. I can capture this fail in the fault handler. What I want to do it if it happens is push the login screen to the user.I have tried the following
var navigator:ViewNavigator;
navigator.activeView.navigator.pushView(views.LoginScreen);
But this is not working and fails with Cannot access a property or method of a null object reference. which makes sense. so my question is how can I get a reference to the current running view navigator object and push the view?As requested here is the full remote object class
My problem is that when I try to pass an object from the navigator.pushView(view, dataobject), I can't figure out how to access the dataobject from actionscript. I can access {dataobject.property} from MXML easily, but I want to set a variable in the new view to the passed dataobjects property.
I'm currently using RobotLegs with the Presentation Model pattern to develop a Flex 4 project. I understand that all business logic related to a View resides in the Presentation Model associated with that view, however, I am confused when it comes to View specific logic.For example, I have an indicator that needs to be positioned relatively to list items depending on which list item is selected. Is it acceptable in the Presentation pattern to put the logic that will position the indicator in the View and simply have that logic run in reaction to a selectedIndex property changing in the presentation model?The reason I am considering this is that since the Presentation Model does not have a reference to the view it is difficult to come up with an ideal solution for manipulating view components.
I have one .mxml file (the Application) with a ViewStack (with 4 views) and a ControlBard, obviously I can change the views with it, but what I want to do is: in view #1 I have an image which I want to convert to a "hyperlink", so when I click it I go to View #2, is this doable? Also I would like to pass somehow some data (like a String) to that View #2 (lets say the it's a user avatar I click so I want to go to the second view which will show me his profile, that's why I need his name/id).
Lately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes).
So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp?
I have a class in which I have declared an array. The functions in that class are designed to make changes to the array, but it's not working:
[Code]...
Anything I do to customerCheck treats it as if it were a new array. This is especially obvious when using customerCheck.push in addCharToCheck() -- the trace always shows a blank array before push and an array with one object in it after the push... then next time it does the same. I know I'm making some sort of fundamental error regarding the scope of the array within the class but I just cannot find any good information on how to fix it! Moving to AS3 (been coding it for all of about 3 weeks) is a nightmare so far, and it seems to be the 'easy' stuff that causes me problems
I am trying to create a simple board game (a kind of checkers), where users will be able to play online with each other using flex application as a client.
I am using django application to process the game on the server side. And I come across the problem, if one user made a move, I can send it to a server, but how do I let the opponent know about it?
The way I am thinking to do it is to create a timer and send requests to the server asking was opponents move done or not....But here we have 2 limitations:
1) Each client would produce big amount of requests (not sure how server will work if I have e.g 100 such clients)
2) If players will chose game with a time limit for example 5 minutes/per game it will be very important to show them situation on the board as soon as it changes (without a pause), but timer will send request only on timer event, so if for example I will chose tick interval to 5 seconds it will mean that 5 seconds another side will not be aware of the situation changes.
I want to push data to flex clients. I am talking about anywhere between 5000-15000 concurrent users, need to get data every time a currency is changed so that means lots of changes for lots of users.
I have been looking into WebOrb.net, but the performance seem very poor (100 users concurrent) for a product so pricy (we purchased a license).
So, I have to look into alternatives, I know there's fluorineFx but it seems no one is really using it for products and it lacks in examples and documentation.
My question is: what products can answer my needs (.net backend) and what are the performance I can expect out of these products?
I'm having a very weird problem with a vector in my application.
Details...I have the following classes.
Person,Player,PlayerController.
Player extends Person. Person extends ObjectProxy in order to enable binding.So the Player class has the [Bindable] tag.The PlayerController class contains a remote object calling a php method to receive a firstname and a lastname and when the CallResponder gets the result from the call,the result handler creates a Player instance. At that moment I am trying to push the player object into a Vector..
The problem is the following.Every time the push method is called, the vector is being populated with the last player that was created but not just in the end of the vector. It replaces the other instances as well! So the vector always contains the most recent player instance but in every position of it.I have also tried doing it with an Array and the results are the same.
So I have a PHP proxy that gets information from a website. Let's say the proxy gets the information from (www.example.com). It checks if the number of lines returned is the same as before, if not then there are more lines, it counts the difference then it need to push this information to the Flex client saying that it has new information, (x) more lines have been written.I am not really sure how to do the push mechanism on the php proxy because I am not sure how to actually push from the proxy to the client, never done it before.
Apart from using BlazeDS, are there any pre-existing libraries that implement long polling (or server push) in Flex?I've read I like to implement Flex to Server comet / long polling for games, but he's only asking if it's possible to implement... Not if implementations exist.
Is it easy to implement Flex Ajax Bridge with ColdFusion? Where can I learn how to use it? My frontend is pure HTML+JS and I just need the push capability. I thought of using Websocket Event Gateway and Server Sent Event (aka EventSource) but seems like they don't have much browser support quite yet. Any pure jQuery short/long polling option Any good Server Sent Event polyfill solution available for older browsers?
I have been using flash since version 3 as a designer.I want to know how to make an object that I have manually placed on the stage from the library with a Class attached to it, interact with the Document Class? So I am basically dragging the item onto the stage and this item has a class attached and the Document Class with all of its SubClasses needs to know this exists.
Now I was dabbling with making geometry wars to learn AS3 Classes and it was great fun, I set up the Document Class, my enemies and Player 1 Spaceship. I worked out my different SubClasses, and everything was added to the stage by AddChild() along with all SubClasses being created through the Document Class....Every Class Object was linked to the Document Class as everything was created either by it or through SubClasses under it. So I had full control to do what I wanted. However, all I ever see are elements generated dynamically to the stage. As a designer I want to animate things here and there and then at specific times possibly gain control of this item with it's Class attached, but I want the Document to have a link to this Item.
Also can everybody please stop generating text boxes dynamically all of the time. just create a MovieClip with the form elements on it if it's a form that isnt going to change in layout at all. But this leads onto the same sort of questions, the items arent being created and added to the stage as objects so you still have to make the MovieClip Class understand the items under it exist, I would do it by the Instance Name but is this dirty these days in AS3..
I'm having a big of a problem, basically when I'm loading an external SWF file, I place in the stage the preloader, I have three symbols for the preloader, the loadbar, that loads across the stage, a circle animation, and a dynamic text that shows the description what is loading. Well when the preloader comes to the displayList, the dynamic text seems to fly off the stage, but when I do a trace statement of the x and y value of the text, it shows 413, but it still goes off the stage. I'm not sure exactly why I'm getting this. The dynamic text is embedded inside a movieclip, and I move the x/y value of the movie clip.
I am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want?
I have a flex UI which communicates with server using spring blazeds. I have a very typical requirement of Live data streaming on a panel in UI. Requirement is like this, We have an object say, Person and server keeps pushing its data on blazeds message destination where UI panel consumer has subscribed and hence user can see this live data in a panel. User can open multiple panels in same browser to view data for different Persons at the same time (e.g id=1,2,3 respectively). There can be multiple UI users who may be viewing the same data for person id=1 at a given time, lets say.
Basically I want to separate data between UI panels. UI panel opened for person id=1 must not display data of that for person id=2. I am doing this using headers-selectors, but apparently I found out that the differentiation to select and display what data happens on UI which is causing performance issues. I learned that using subtopics may improve performance. But, before proceeding for it, I want to know, will UI browser end up in receiving data irrespective of subtopic assigned to data and then consumer will decide to accept it or not?
I am working on a server push from Java to Flex. But some how the MessageBrokerServlet is not getting initialized, seems like it is calling a method from: flex.messaging.config.LoginCommandSettings.setMatch() Eventually I found out that this method indeed does not exist in that class (LoginCommandSettings). I there something else that is going wrong?
I've got a very simple project in FlashBuilder 4.5. It's a mobile application of type ViewNavigatorApplication with a single view, MapView. In the MapView.mxml file, I've got a Flex component of type Map declared in xml.
[Code]...
In this same project, I've an actionscript class called UserGeolocation. In this class, I'm attempting to get a reference to this map component. So far, I can get a reference to the top-level application, its ViewNavigator and the NavigationStack of said ViewNavigator. However, I cannot find a way to access the MapView, much less the map I've declared within it.
I'm aware of methods like firstView() and activeView(), but I want an absolute solution, one that retrieves the view regardless of whether or not it's first or active. I've tried navigator.getChildByName("MapView") with no luck.
I'm about to have to write a web page/app that will serve the agenda for circa 100 people on a page. One line per person, one column per day with 3 clickable zones in each cell. In HTML, the page is way complex for the browser to load quick and there is no possibility to click on a border between 2 cells to for example split an event that spreads among several cells. So I search an not too overkilling technology to render this kind of view. I begun with a PHP generated HTML page but the number of elements in the page make the mouse move jerky.
Moving to JAVA would give me better performances regarding the reuse of the generator of the view but it will still be an HTML page. So, here is my question: do you think that going forward with JAVA and its graphical capability is the simple solution or is Flash a better option for this part of a Web App? I'm afraid of the code I'll have to write in JAVA to handle the GUI presentation as well as the events generated by the 1000's cells plus borders of the page. In Flash, the graphical part seems simpler even if the actions handling is still huge.
I am wondering how to make a 360º view bubble, like they use for Google Street View, but have no idea how to go at accomplishing this task... i have the string of photos that i attached in photoshop(so that if you connected the left to the right it would be a full 360º view).
There is a Flex app with 7 main views. And there is a memory issue when navigating between views.All these views were in a ViewStack, but due to some involving 3D objects I assumed it was too much to have it all in the display list. I'm now clearing all children from the stack and adding/removing them when needed. This gave a small performance increase, but still becomes unresponsive with use. The strange thing is, with this and the original method, the CPU climbs with use but eventually levels out somewhere. Now I'm creating new instances of each screen when they are navigated to and setting the previous variable to null. Now it looks like CPU is spiking when the view is created, but leveling out to something much much lower than it was. This felt like progress, but now the available memory keeps climbing where it wasn't before....
My understanding was calling remove child or remove all children would mark the object for deletion when the garbage collector next ran. I can't see any other references to the instance. My code is along the lines of [code]I have a function for each button to add a new instance like the above.The only thing I can see and feel silly asking but need confirmation, is each view extends a class called "Screen", this class contains a singleton reference to some core components.[code]Would this trick the garbage collector into thinking it was still needed? General advice on clearing Objects from the memory pool would awesome!!! I've never needed to analyze the Flash Player in such depth.I think it's an error with sound drivers, removing all sound and shes purring like a kitten. Works on my machine fine with windows XP, but not on the touch pad the application is crashing on with windows 7 (unsure of the drivers looking into them now) Now I'm thinking its not the drivers, tried 3 different versions, all with no improvement. I did discover the sound was fading in and out with the TweenLite lib. Doesn't look like there are any memory leaks in TweenLite as it works fine on other machines. Just the use of volumeEasingFunction seems to consume increasing amounts of CPU until it freaks out. It is crappy hardware running windows 7, which doesn't help.
I have four views:1.SplitView (main view)2.SplitViewHomeView(root Panel)3.SimpleView(Right panel)4.Details(child of Right Panel View).I am trying to accomplish the split view as in Ipad in adobe flex mobile.But unable to connect the root panel to right panel...Can any one suggest the path to me.My Code is below
I am using Flash CS4 AS3.. When I open my browser "Internet Explorer 7" it opens normal. But When I open a link using the following Flash code it opens half in length and half in width. I need to click on "Maximise" button to view in full. How to solve the problem? It is our Intranet link.
in flash, I encounted a source file that is cropped and I cannot move it, is there some sort of cropped view in flash I dont know about? I cannot find anyinformation about it, it has rulers displayed as far as I remember.
Basically you cannot move in the file to edit anything viewpoint wise, everything outside of the movie area is invisible and not there? As if cropped.
I have started learning flex 4 and I got myself thinking about how to change views. So I have a question what do people usually use - states or views (ViewStack). The type of web application I am making, can use both, but what do developers use in big projects or maybe they use non of the mentioned before?[code]...Best view architecture in it?
I want to create log file for my flex application. That is the file should contain all the trace prints in it when I run my flex application. How can I configure flex to do this?
