I'm trying to convert an MXML component to an ActionScript Class. The component consists of a Form with a TextInput, TextArea, and two buttons - Save and Cancel, and a Validator for the TextInput, and other logic to handle events that occur. This component is currently extended by several other components. Now, in the MXML component binding the TextInput text property to a property in an Object was very easy:
<mx:TextInput text="{_itemToEdit.name}" />
But in ActionScript, I'm creating the TextInput and setting the text property before the Object is set, and the TextInput is not being updated:
public var itemToEdit:Object = {};
private var nameInput:TextInput = new TextInput();
public function MyClass() {
nameInput.text = itemToEdit.name;
}
How can I make sure that the TextInput text property is bound to the specified property in the Object?
I'm looping through a recordset, and for each item I create at runtime a spark Label and set the text property from a field of the recordset. The labels must have a fixed width and some text goes multiline. I want to arrange the label vertically so I need to know the height of the label so I can place the next label properly, but when I try to read this property, after the labels is added through the addElement mehtod, it returns 0.
how to get the label height?
I am using the combocheck example from the following site: [URL]
It's a very useful component and works very well.
Now, I need to set the text property of this combo box upon application startup with certain values (which are defined dynamically according to some criteria). The problem is that although I have no problem setting the text property of the combo box at other times of the application run, setting the property at startup seems to have no effect unfortunately.
For example, I want to set the text property of the combobox to "Bob" (which is one of the items in the dataprovider for the combobox) and the "set text" method is called on the combo box. Performing a step-through shows that the "set text" method is receiving the correct value item but not setting the _text property.
I have tried not doing anything until "ApplicationComplete" but no joy there either.
Here is the code (a combination of the code from the URL above and some other changes to it). However, as I've stated above, the codes does work. The problem is that it doesn't work at the application startup. Whenever an event is fired and setComboText is called as a result, the text of the combo box is set correctly.
private function onComboChecked(event:ComboCheckEvent):void {
var obj:Object=event.obj;
var index:int=selectedItems.getItemIndex(obj);

I seem to be having a recurring problem attaching events to a button i have created within 2 other movieclips.I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
So it looks like it can't find the button, in order to attach the event listener. The question is why? I am attaching a similar event to a button on the main timeline and that works fine. So it looks like a scope issue, but I am referring to it properly.
code below:
Code:
import flash.net.navigateToURL;
import flash.net.URLRequest;

Short version:Setting a TextField's 'text' property seems to be quite slow. Any way to optimize this?Long version:For a video player I'm working on, I've rewriting a bunch of code I've written in the past and optimizing where I can, and I've noticed something a bit strange.I have a time readout (the typical "00:00 / 01:00" thing) that I'm updating every frame, and it seems to be gobbling up FPS (I'm using mrdoob's great little Stats class for monitoring).The thread to make the call is a bit heavy -- involving a dispatched custom event from the FLVPlayer class (with the current netStream.time as a property) onEnterFrame, which is passed up 2 parents and then back down via a function call -- but I've isolated each step along the way and everything is totally fine (running at or close to 30fps) right up until that very last call where I set the TextField.text property, which results in about a 10fps drop.
If I comment out the setting of TextField.text it runs great, but even if I set it to something arbitrary (like currentTime.text = "0") -- bypassing the reformatting math -- it just tanks.Anyway, anyone know if there's something I can do about this? I've considered using a Timer set to 100m instead of onEnterFrame, but I actually assumed the overhead would come from the dispatching of and listening to the event as well as the reformatting of the time, but *not* the very last step of setting the .text property, which is something I can't avoid whether I use a Timer or onEnterFrame.
<mx:Canvas id="maincanvas" backgroundColor="7000" width="100%" height="100%">
<mx:TextArea backgroundAlpha="0"/>
</mx:Canvas>
However if I try creating a new textarea object via:
var textarea:TextArea = new TextArea ();
textarea.backgroundAlpha = 0;
maincanvas.addChild(textarea);
flex throws the error :
1119: Access of possibly undefined property backgroundAlpha through a reference with static type mx.controls:TextArea.
So I am loading clips and images into a swf file for a portfolio site. As I test the site to debug I sometimes get a #1009 error and sometime I don't. Even when I test without changing anything and go through the exact same sequence of actions to try and get the error again it only throws the error about half the time.
I don't understand why it would do this at all since the file works flawlessly sometimes so my code is accurate. Any ideas? I have heard about display lists before and wonder if maybe that might have something to do with but I don't know what a display realy is or how to make sure that things are on it... I'm confused.

well in my game,while you are playing level you have 3 objects(movieclips) on which you can click to pass on the next frame(when comes 3 new objects etc. untill level is complete); 2 of that 3 objects are wrong, and only 1 is good for passing on next frame. (all of all, correct click, wrong clicks)when i come on that level it keeps me showing error in output:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at TestYourLogic_fla::MainTimeline/goodplus();
Code: Select allfunction goodplus (event:Event):void {
goodcount ++;
goodText.text = (goodcount.toString());//<----debugger is showing error here
}
i gave instance name on my dynamic text as goodText, and it is on every frame.
I changed my html template to include flashvars like so:
if (hasRequestedVersion) {
// if we've detected an acceptable version
// embed the Flash Content SWF when all tests are passed

And I am trying to access them in my app like so:private static var _PID:uint = Application.application.parameters.product_id;
But I am getting this error:

I have this MenuBar control in Flex 3. How can I programmatically change the toggled property to false?

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 am trying to use a button in my init() method.

creationComplete="init()">
Now when I try to do something with my button I get the error mentioned. I am assuming maybe it has not loaded yet?

I have a flex application which use DragManager.When I'm loading this application into flash application and trying to use drag'n'drop functions - I get an error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at mx.managers::CursorManagerImpl/showCurrentCursor()
at mx.managers::CursorManagerImpl/setCursor()
at mx.managers.dragClasses::DragProxy/showFeedback()
at mx.managers.dragClasses::DragProxy/mouseMoveHandler()
But, when I simply run a flex application (not loding it into a flash one) everything works properly.
Can we put [Bindable] on functions/methods? I know that bindable is used to change the value of the source property to destination property. But not sure if we can use that for methods. why we cannot put/ if we can then what will be the outcome?

I'm new to flex and actionscript. I'm trying to create a small flex app that has multiple states, but if I have nested containers, it looks like some of the objects are not getting initialized when I expected them to be, even when I have the creationPolicy set to "all."I've reduced the issue to a small example, with a commented block showing when it does work.sing the existing code, I get this error: "TypeError: Error #1009: Cannot access a property or method of a null object reference at main/init()" and the event handlers are not installed.If I instead use the commented block, which has the Panel and VBox elements removed, it does work.I know I could add a click attribute to the mxml elements, but this is just a simplified example, and I'm more interested knowing why the objects are not initialized when the app loads.

I run my code, it will give me a "Cannot access a property or method of a null object reference" error. I double checked, I realized when the program run until the component file up to the accessing dataGridData variable, that dataGridData variable is null at that time. That is probably flex initiate the component file before it send or get the xml data from server in main. Which cause the variable is still null at the mean time.
I have this custom class which extends EventDispatcher
private var assetsManager:AssetManager;
And this running on creationComplete
GeneralUtils.parentComponent = this;
this.assetsManager.addEventListener(AssetEvent.ASSETS_LOADED,OnAssetsLoaded);
this.LoadConfigFile();
I'm getting 1009 errors on the second line. I've been looking at this for a while and can't figure out what it can't find. The OnAssetsLoaded function is there.

I have been working with Flex and ActionScript for a few years now, but am just now getting into switching locales dynamically in one of my applications. I have set up locale bundles and have everything working well except for one thing I can't seem to get to change...the internal labels and date formatting on a DateField component.The DateField component is defined statically in MXML, but I am trying to change the dayNames, monthNames, and dateFormat attributes dynamically when a user changes locale, and it doesn't seem to work. have bound variables set up in the MXML that I am trying to change for all 3 of those attribute values, but they don't seem to change when I change the variable values.
I've tried making invalidateDisplayList() and invalidateProperties() calls after changing the values, but that doesn't seem to matter. I even added a call to "initialize()" after the 2 invalidate calls thinking maybe that needed to be called, but nothing seems to make a difference in getting the labels updated within the componentwhat I could be doing wrong? I've verified that the newDaysArray and newMonths array are getting set up properly from the bundle that they are being read from in the actionscript below.I should add that I've also tried editing the appropriate array variables in theSharedResources.properties file within the appropriate locales' framework_rb.swc library in my Flex sdk, and that hasn't seemed to do anything either.Here's code snippets:
MXML:
Code:
<mx:DateField id="dayChooser" formatString="{formatString}" dayNames="{daysArray}"
