Flex :: Refreshing HiearachicalData Based On Source Updates?
Apr 4, 2011
I have an ArrayCollection we'll call "Items". It is essentially a flat collection of hierarchical data (each item has Parent and Children properties). I want an AdvancedDataGrid to display the data in hierarchical form, so essentially I could just do this and it would display fine:
// Note: RootItems would be an ArrayCollection that is updated so only the
// top level items are within (item.Parent == null).
var hd:HierarchicalData = new HierarchicalData(model.RootItems);
i have a Air Project in which i have added three extenal source folders. but when i reopen project or strat flash builder again i get icon on those folder like this but when i open the configuration for that project and try to validate the path and adding it again i get message like this but the path is valid. proof is this pic what could be possible error,,, is there any way that i when ever re-open project i get no warning and able to navigate through the linked source code. now i am doing it
So inside my src folder I have my app.mxml file. I have a source directory pointed to my actionscript library.It appears that Flex does not look inside that source directory including an .as file within the master mxml file.
I could just have the main app.as file inside the src folder along with my app.mxml file but it would be nice if it could live in the actionscript library.

I am looking for a Flash based image uploader with resize and possibly rotate function. I have checked many possibilities, and the very best in simplicity and unser experience I found is Kroppr at a very affordable €29/license. The downside is, it comes with encrypted PHP code to bind the product to a subdomain. That is understandable, but while I'm perfectly happy to pay money for a tool as great as that, and ready to sign all sorts of legal agreements to protect the license, I am not ready to use encrypted PHP code, especially not from an outlet that doesn't even have a postal address on its web site.Does anybody know an Open Source or commercial solution that comes close to Kroppr and ships with source, or allow for full customization and free definition of the server-side backend?[code]The server side technology would preferably be PHP.
I need to find a flash video player that is free and open source. I love flowplayer and jwplayer but we fit into their most expensive licenses. It will cost us over $1400 to license flowplayer for our use. We don't have that right now.
I just need a flash player with a basic javascript api that is truly free. I have been googling for hours and nothing so far.
It would be a huge plus if someone knows of a chromeless youtube player that uses the youtube as3 api. I don't have time right now to code an entire chromeless player complete with all the controls and a progress bar.
I'm trying to get two different apps to communicate through a file. I would like app 1 to append some text to a file, and app 2 to notice, and read the new bytes (not the whole file). There is an event, ProgressEvent.PROGRESS, that is supposed to fire when new data is available on a FileStream, but it only fires when I first open the file. Basically, I would like to leave the FileStream open, listening like a socket on the end of that file for changes.
I have a flex application that has a home button. I need to reset the application when this button is clicked. I can't use navigateToURL or ExternalInterface.call("window.location.reload"); as its not acceptable to reload the swf file.
I am using Flex Builder 3, working on a PC. Everything was working as expected throughout my first day of code updates, but on day 2 Flex started behaving badly.The problem started when I removed a component, and then got an error that it couldn't find the specified component in some accompanying AS3 code. No problem, I updated the reference so it wouldn't look for the old missing component (a form item). When I compiled the project in debugger to check my work, it failed when it got to that part, and gave an error that it couldn't find the component I'd removed. However, my code had fixed the problem, and the error was referencing a line of code that wasn't there any more. I proceeded to change the file around greatly, and even resorted to creating a new file, changing the name of it, and then recompiling it. I did a clean compile as well, rebooted my machine, restarted Flex, but every time it gives an error referencing the bit of code that isn't even there any more. It's as if it's loading a cached project each time (both in debugger and run mode).
For reference, here's the error I'm getting: ReferenceError: Error #1069: Property Winter Cost not found on views.PopupUsage and there is no default value.Well, the file "PopupUsage.mxml" doesn't even exist any more and is not referenced in my project at all, but it's still being referenced by Flex when I compile the files.What can I do to make Flex move on and look at my code?
I have a ProgressBar in MANUAL mode responding an URLLoader's progress events that seems to get drawn far less frequently than I would like. If I debug the app, I can see many events firing from the URLLoader yet it seems that the ProgressBar is being re-drawn at some random and slow rate.
Now if this was my own code (URLLoader is a black box), I would pause once in a while to let the UI update, say via loop with a timer. I presume that the URLLoader itself is blocking the main thread from processing drawing code. Adding validateNow() and invalidateDisplayList() does not seem to help much.
Now there are many TResources (just a class that can manage its data) being loaded in sequence, but the URLLoader is so greedy that it does not let the UI get updated more than a few times when loading & processing (parsing into XML objects) 50 or so 10KB files. So just counting which files loaded visually does not work either; I'm lucky to get 2-3 screen updates the entire time.
Loading a 700MB file looks much better, but again the progress bar updates are random and slow.
Additionally, I'd like to know if there is any way to influence or even control the rate at which ProgressEvents are fired by the URLLoader class. I have not been able to find at what rate it normally dispatches progress events either; is it at a fixed percentage per file or every x frames or milliseconds?
As these are local files, would I be better off not using the URLLoader class and instead switching to FileStream?
I'm having a problem refreshing an xml file. I am bringing it in through an HTTP service component and putting it into a bindable array _cattArr, that I am using as the dataprovider for a grid.When someone adds an item to the datagrid, it saves to the same xml file. Then I close the window, reopen it and don't see the item that has been added.It is writing to the xml file, because when I restart the flex app, the item has been added, it's just not refreshing it. I have tried to resend the httpservice, but still no luck. What is the correct process for doing this?
I have a problem..I am binding an array collection to a datagrid in flex. My problem is whenever i try to remove an item from the array collection.. the datagrid does not refresh the values....This is the code that I am using
[Code]....
eventsList is the datagrid that is bounded to showArray(an Array Collection)
Is there a way to refresh a component or an application back to its initial state? I have an accordion navigator that stays on the most recently selected index even if I log out. Right now, my log out function takes me back to the login page which is at state(1). If I log back in and go into the accordion, it is on the last tab I had viewed.I would like to be able to clear any data from the controls inside the nav and reset the nav back to its default. I thought something like,
public function logout():void{ currentState = "NotLoggedIn" myAccordion.initialize(); }
would work but nothing happens. This is done in Flex 4.I know I can make a huge loop clearing each control individually and setting the selectedIndex of the accordion to 0.
Flex application is contained in one of the rows of a html table, and that row is hidden as per one use case. Flex application is refreshed when visibility of the row is changed to visible. This results in lose of data that is already entered in the flex application. Is there any way to stop this behavior?
I'm working on my first ever AIR application with flashbuilder - just so you know. I've bound a mx:DataGrid component to a DataProvider which is a mx:HTTPService fetching an xml file with items. To keep the data up to data I'm polling the webservice on a given interval.
My problem is that I loose the currently selected item in my DataGrid when the data is updated. I've tried to save the DataGrid.selectedIndex and set when the data is updated, but I'm not sure when to do it?! The closest I've come is to restore the index when the updateComplete event of DataGrid is fired. This works, but the selection first fades away and then fades in - not updated soon enough. So what is the best way to keep the selection? (only one selected item at a time) And as a side question: is there a convenient way to only update the data when it has actually changed?
Within a child, I have an XML element with the following structure:[code]I then use a repeater to list each out onto the screen. There's a button I have created that is used to create a position. So, once the user clicks this button, I call the following function:[code]The above function creates a new XML object, puts some default values in, and appends it to the list of project positions. After appending the new information, I made the height of the project larger and then check to make sure the new project height isn't overlapping any other projects... but that information is irrelevant to this post.My problem is this - once i append a new child to the XML variable, it doesn't appear on the screen. Is there a "refresh" or "re-render" option i can do to the repeater in order to make the new child show?[code]Once i make the changes, and use the XMLListCollection as the dataprovider in the repeater, the information no longer loads on the screen.
My first issue is that when my ArrayCollection only has one item, for some reason I cannot select that first item. The change function set on the mxml never gets called when I try to select that one item. If I set a prompt, it works. I know that the item is not already selected because when debugging, the selected item shows null. I do not want to use a prompt. I want the first item in the ArrayCollection to be selected automatically. So if there is only one item, I want the selected item to be that. FYI - I am using a labelFunction to format the data in the Array Collection. why I cannot select the first item or set the first item in the ArrayCollection to be the selected item?
My bigger issue is that when my Array Collection gets updated, my label function must not be refreshing because when I first open the dropdown, it has specfic data. When the Array Collection gets updated and I open the dropdown again, I see the old data in the dropdown, yet it doesn't exist anymore.
So let's say I have a ComboBox that has a datasource of an array collection of one state code and it's state name. Their is a labelFunction that puts a dash in between the state code and the state name. Their is no prompt, so the ComboBox would look like GA - Georgia and when you open the dropdown, that would be all that is there. I want that item to be selected automatically. why the old data shows up when opening the dropdown after the array collection was updated with new data?
<mx:ComboBox labelFunction="getFormattedNpaNxxCollectionList()" dataProvider="arrayColl" change="doSomething()"/> public function getFormattedNpaNxxCollectionList(item:Object):String { return StringUtil.substitute("{0} - {1}", item.stateCode, item.stateName); }
I am using many external swf file in my flex application,but when i use the files which are in same name its not getting refreshing properly, so i need to delete my temp file without refreshing the application.
I have 2 movie clips, one being loaded into a container MC via "loadMovie();"In the main movie there is a variable with no value, in the external movie there are 5 frames, each with a value to update the variable in the main movie.
IE: if on frame 1, global value = 1 / if on frame 2, global value = 2 / etc etc I'm familiar with passing variables INTO an external swf, but am stumped on how to do it the reverse way.
I have what seems a straighfoward situation: I update the source property of an image, when the image is loaded i want to redraw the border skin to fit the new size of the image.
newImgEdit.addEventListener(Event.COMPLETE, loadImgComplete); newImgEdit.source = myurl_ressource; private function loadImgComplete(evt:Event):void {
I'm using the update function of Adobe Media Encoder and see that an update is available. I click on download and install it. Everything works fine and I get the message that the update was installed successfully. But when I start AME again it still shows 4.0.0.374 instead of 4.1.0 - what's wrong? I never had this problem before. I also tried to download and install the update by hand. Same result.especially when I see that the contact form of Adobe's customer support portal is offline.
In Flash Builder (flex 4) I try to use next code to set selected by user (from file system) Image as a repeated background. It worked with mx:Image but I want to use cool repited capabiletis of s:BitmapFill.BTW: Technic I use also does not work with S:BitmapImage. Also FP does not return any errors. What Shall I do with my code to make it work?
I would like to compile my view classes into an SWC from flash, and compile the rest of the application using mxmlc (avoiding recompiling through the IDE). However, because the view classes (source) are in the project class path, mxmlc gives them precedence over the compiled SWC.
Now I'm thinking that maybe the view classes have to be separated into a separate project, but I am hesitant to do so because I don't think these classes truly constitute an independent project, and separating them out would not serve any purpose beyond working around the linking precedence problem. Furthermore, if i were to change my mind about the linkage, i would have to restructure both projects, and any common dependancies between the two projects could be messy to maintain.
How can I get mxmlc to give precedence to the SWC over the Actionscript? Or, if this is not possible, is it more common to create a separate project for the Flash-compiled library, or to isolate the Flash source in the project so that it is not included in the project class path?
I've added a ProgressEvent listener to an instance of FileReference. At different times in the code I call both upload() and load(). How can I isolate the progression event of only the upload method?
