Actionscript 3 :: Flex Textarea Control Not Updating Properly
Apr 19, 2010
I am writing a flex application that involves modifying a textarea very frequently. I have encountered issues with the textarea sometimes not displaying my modifications.[code]When you run the above code in a flex project, it should repeatedly print, character by character, the sentence "The big brown fox jumps over the lazy dog.". But, if you are typing into the textarea at the same time, you will notice the text the timer prints is distorted.I am really curious as to why this happens. The single-threaded nature of flex and disabling user input for the textarea when I make modifications should prevent this from happening, but for some reason this doesn't seem to be working.I must note too that, when running the timer at larger intervals (around 100ms) it seems to work perfectly, so I am tempted to think it's some kind of synchronization issue in the internals of the flex framework.

I am developing a Flex based window application. In that I have used a textArea, Now when I type some characters like ctrl+b, ctrl+e or ctrl+q, it shows some square characters in text area, I think these are some unicode characters but why these are being entered.
Unlike in simple textArea control on adobe example when I presses these key combination, there is nothing being entered, so why this only with me.
This is my window setup code
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute"

I'm working on a simple view in my app that allows a user to drag an item from a list control and drop it onto a textarea.
Seems the dragEnter event fires just fine, but the dragDrop event does not.

I have an app that has text appended to a TextArea (TA). It automatically scrolls to keep the recent line added in view. Over time, this could be a lot. Do I have to worry about this? Is there an upper limit? And, if so, how can I prune the oldest lines of text?

There's an annoying bug in AIR (or in the TextArea component itself but showing up only in AIR) because of which, if you do:
my_textarea.htmlText=someLongText;
my_textarea.textField.scrollV=someValue;
the second instruction just does not work, and the textarea scrolls to the beginning (as a consequence of the first assignment). Has anyone else run into this and have you come up with any workaround?
This only happens in AIR, not FP, and only with TextArea, not with a plain input text.

I'm trying to update my text area via ActionScript code using this: scoreLabel.text = this.score.toString(); but it's not behaving correctly. When the score is 18, the text area displays just 1, when it's 26 it won't display anything at all... As a test, I tried doing this: scoreLabel.text = "this is a test"; and now the text area is just displaying e: [URL] This isn't a font issue, as I'm using Arial. What is going on here?

I have created a textArea element but cannot display my HTML content. If I just display regular text it works or if I change the textArea element to a RichEditableText element it works fine. Since this is for a mobile app I would prefer to use the textArea element as recommended by Adobe.Here is the MXML code for the textArea. All I get is the border and no content displayed.
<s:TextArea id="myHelp" editable="false" width="100%" height="100%">
<s:textFlow>
<s:TextFlow>[code]..........

I'm having issues with the property "editable" of textArea control. I have a component: OrderView.mxml and it's associated data class OrderViewData.as. Orderview.mxml is inside a viewStack to enable navigation from a component to another. In this particular case, OrderView.mxml is called by another component: SearchResult.mxml. I can thus navigate from SearchResult.mxml to OrderView.mxml, and back to SearchResult.mxml... OrderView.mxml has textArea and textInput control, that have to be editable or nonEditable depending on the property var isEditable:Boolean from OrderViewData.as.
When the application is launched, isEditable = true. So, all textInput and textArea controls are editable the first time the user gets to OrderView.mxml. When the user clicks on the button order from OrderView.mxml, isEditable = false. When the user goes back to SearchResult.mxml, isEditable = true (again) --> Until here, everything works fine. The thing is: when the user goes back to OrderView.mxml for the second time (and beyond), even if the property isEditable = true, textArea controls are still non editable... But the textInput controls are editable!

I'm just about to uninstall and reinstall at this point but I'm getting my install all screwed up trying to update Flash Pro CS5.5 to use Flash Player 11. I had it fine using the MXP provided in this adobe blog. Though that's 11.0 not 11.1. It did work however.
I downloaded the latest Flash Player / Debugger .exe and the latest SWC for 11.1 and now Stage3D is no longer being seen. Clearly I screwed something up. I uninstalled and reinstalled the MXP after deleting the FP11 XML and FP11 directory but it's not working anymore.
Is there a clear cut simple way to explain how to overlay the latest Flash Player for FPCS5.5? I used the AIR overlay instructions for 2.6 - 3.1 and it worked every time. Now I just need Flash Player overlay instructions. I'm very interested to start trying to Starling framework with Stage3D. I select FP11 to export and it tells me it can't find Stage3D.

I have a for loop updating a dynamic text element but it seems to iterate so fast that only the last item in the loop is updating the text. I'd like the dynamic text element to be updated with EACH item in the loop, not just the last.

I'm resizing a chart and want to take a picture of it when all the children of that chart are done updating.
For example I'm drawing some stuff on the chart after the size changes. I've tried chaining a bunch of callLater() but I'm still running into problems on slow computers.
Raising an event when the last children has executed doesn't seem to work as it might take a while to draw (hence the callLaters).
Is there a best practice to find out when something is done updating?

If you have two text areas with different styles (fontFamily, weight, color etc) and you copy text from one to the other it also copies the style from the originating text area. Is there any slick way to prevent that?
Here is a sample of code that will illustrate the problem. Type some text in the top box and some text in the bottom, then copy some characters from the top box to the bottom. I'm not using htmltext.[code]...

My Combobox is not alway updating when I update the ArrayCollection.[code]...
the first time it updates the combobox fine and sometimes it works the 2nd, 3rd, etc time is might update the combo box. After it stops updating the combobox, it never does until I restart the app. I have verified that the ArrayCollection is updated via the debug data, it is just the combobox is not updating the display.

I am trying to work with a global variable in Flex and it does not appear to be working correctly. In my default mxml file I declare the following
public var appID:int;
This variable keeps track of the session ID across my application for SQL purposes. On another mxml page I call the following code which should update the global variable to the current ID.
// Get the ID
sqlStatement.text =
"SELECT Max(id)FROM applications";
sqlStatement.execute();
var result:SQLResult;
result = sqlStatement.getResult();
FlexGlobals.topLevelApplication.appID = result.data[0];
Lastly I run a SQL Update query using the ID as a parameter. My problem is that the FlexGlobals.topLevelApplication.appID is always 0, for some reason the global variable never gets updated, I have checked to ensure that result.data[0] is correct but the value never gets passed to the global variable.

Is updating a Flex Mobile Application done in the same way an Air application is updated? Can't seem to find information specifically for mobile on this. Apparently, if I trace out Updater.isSupported, it gives back false. From the Adobe documentation: The AIR update framework is only supported in the desktop profile. It is not supported for extended desktop applications (applications installed with a native installer), and it is not supported on the mobile profile (iPhone applications written with ActionScript 3.0). Check the Updater.isSupported property at runtime to see if the update framework is supported. So how do you implement updates for Mobile Apps created with Flex (Android + iOs)?

I'm new to Flex and am having trouble understanding Events. I think Events are what I want to use for my situation. I have 2 components, addUser.mxml and listUsers.mxml. I access these from a ViewStack in my main application. When I load listUsers.mxml it shows a list of current users in a datagrid via a HTTPService call. When I add a user using the form on addUser.mxml I would like the datagrid in listUsers.mxml to refresh when I return to that view to show the new user. I've tried several different things with addEventListener and dispatchEvent but can't seem to get it working. Can someone help me with this logic?

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 have an item renderer for a grid that has a fairly basic updateDisplayList function:
override protected function updateDisplayList( w : Number, h : Number ) : void
{
super.updateDisplayList( w, h );
var labelWidth : Number = Math.min( _labelDisplay.measuredWidth, w );
[Code]....
The next time I scroll the renders update to look like they should - but updateDisplayList is NOT called here (on the renderes). All that happens is that the renderers are re-positioned in the grid. Both the background and the label are displayed incorrectly initially so it's not just the label mis-behaving.

I have a Spark.List with several items ("folders") each containing an ArrayList of files inside, when I select one of these "folders" it should display the list of "files" on another Spark.List. Its working right now by doing this:
private function onFolderChange (event:*):void {
var list:List = event.currentTarget as List;
if (list.selectedIndex != -1) {
currentFolder = null;
currentFolder = list.selectedItem;
fileListDataProvider = currentFolder.files;
fileList.selectedIndex = -1;
}}
The problem is that when the "file" thumbnails cover more then the List viewport and a scroll is needed sometimes by changing from a "folder" to another "folder" the file List loses files. For example lets say there is a "Folder 1" with 30 "files" in it (10 visible and 20 hidden by the scroller) and "Folder 2" has 5 "files" (all visible), if I switch back and forth between "folders" sometimes it will display everything right. Sometimes it will display a scroll on "Folder 2" when there is no need and sometimes it will only display a few (5 or 10) "files" in "Folder 1" even though it has 30. Something is wrong with the fileList, its updating its items but not really updating well. I've tried setting the itemRenderer to null and reapplying, setting the dataProvider to null and reapplying, doing validateNow().

I've created a component which is basically a meter (extends skinnable container). The skin to the component contains two rectangles (background and the actual meter). This component receives an arraycollection with the following fields value, max and min(the arraycollection I am passing is Bindable). When I initialize and pass the data to be used to draw It works great (keep in mind - only works the first time). I've created a button that changes the data array and shows the current meter value. Apparently the meter's value is changing everytime I modify the ArrayCollection I've set to be used for rendering.(dont want to say "dataProvider" because it is not a Flex dataprovider, just a variable )... here is the code...
public class meter extends SkinnableContainer {
[SkinPart( required = "true" )]
public var meter:spark.primitives.Rect;
