I'm loading an image from an async database in every view of my app. I'm using a view transition in Pop/PushView to change between views.Problem: The image loads after the ViewTransition is complete, instead of before.
And the code:
private function NextView():void
{
selectStmt = new SQLStatement();
selectStmt.sqlConnection = conn;
[code]....
I have decided to go the route of using ViewNavigator and having one view with 3 states. Each state is a "page". It runs just fine on the desktop but when compiled for mobile, the transitions between the pages is really laggy, even for the Samsung Galaxy S. The phone has the 2.7 runtime and I recompiled my application with ADT 2.7, still no performance increase.
I have also tried cacheAsBitmapMatrix on all 3 pages, which are all contained in a VBox and that hasn't shown any significant performance bumps. All I'm changing is the y component of the VBox for each transition.
EDIT: I have done some more research and I am now to the point where I have hardware acceleration turned on and cacheAsBitmap = true and cacheAsBitmapMatrix = new Matrix(). I am also using Stats.as to see the FPS. I notice on my state changes I go from 25 FPS to 2 and then it goes back up again.
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.
View 1 RepliesI 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).
View 1 RepliesMy 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.
View 1 RepliesError #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairsI run into this problem frequently when handling MySQL queries inside of Flash. I can usually figure out the problem, but the amount of time it takes is incredible sometimes. Part of the problem is that I have a hard time pinpointing where the problem is. The reason for that is that as far as I know, there is no way to see the String being passed that is causing the problem. First, is there a way to see this String, and second, if not, how do you typically troubleshoot this error?
For more details: Normally, I am sending data via POST to a PHP script which runs a MySQL query and returns the results. For simplicity and ease of use on my end, I got in the habit of forming the queries in ActionScript and sending the query as a variable to the PHP script, so all the PHP script does is run it (I know its not the best practice). There are a number of reasons for getting the 2001 error. For instance this morning I encountered a 406 : Not Acceptable error every time I sent a query over POST that included a WHERE statement in it. SELECT * FROM table was fine. SELECT * FROM table WHERE userName=something was not (As a side note, I am still puzzled by this as in a different swf on the same server in a different folder, it is running the exact same queries in the exact same method using the exact same PHP code (in a different file) just fine. For now, I'll just stick with the probably better practice of forming the queries in the PHP rather than in the ActionScript). It was difficult to figure out even what the error was on the server since when I navigateToURL() instead of URLLoader.load() all the POST data gets sent as GET and its hard to piece apart if the problem has something to do with the fact that PHP isn't accessing the variable anymore or something else like a security restriction from certain queries to prevent cross-site scripting (which I assume was happening this time).
I used this video to teach me how to create a safe: [URL]The buttons work when I 'Enable Simple Buttons' (not the text input but the Down image shows) but when I export it, absolutely nothing works. The instance name of the text box is 'input_txt' and it is set to 'Dynamic Text' using the font 'Cambria Math'.Here is the ActionScript for one button:
ActionScript Code:
on(release){
input_txt.text+="1"
}
Looking for any help you might be able to give me with this one. Recently upgraded from Flash CS3 to Flash CS5 Pro. When I publish a movie produced exclusively with CS5, the resulting SWF will work everywhere but inside my company's highly restricted/locked down network. When I attempt to load the SWF in a browser from within the network, all I get is what appears to be the standard Flash preloader - the 5 little dots that crawl across the middle of the screen.
I've confirmed there's no IE version error, the machines have the newest version of Flash Player; the only difference is the network. What could be preventing the SWF from reaching the browser? Is there any esoteric publishing setting I can use in CS5 pro that I should try?
I have a drop down list for selecting the titles for a person, I want to employ smooth drop down when i select the drop down menu.

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.

View 1 RepliesCan transitions be added to a source code that uses includeIn and excludeFrom to show/hide elements? It seems that elements are hidden immediately not allowing enough time for the transition to be played.
In this documentation article, a method with visible and includeInLayout properties is used but that would mean I would need to rewrite my MXML code which I'd rather avoid.
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.

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).

and so on....
Now I want to jump directly, with NO TRANSITIONS, from one of the views deep in Tab1, into one of the views in Tab2. How do I do this?
