I am having a real problem with one of my components. I have a list object and I need to set the selectedIndex. Now I would think this would be easy, but it appears that for just this instance the selectedIndex property is read only. I have set the property for other instances, and I can read the property for this instance, but I cannot change it.
View 1 RepliesWhat's the difference between selectedChild property and selectedIndex property? I read the documentation, both seems to be setting currect active accordion. selectedChild can be only used in actionscript, but other than this, what's the difference?
View 0 RepliesI am unable to bind the selectedIndex public property of a spark DropDownList to it's original source in the view's presentation model.
For the purposes of replicating this issue with as few lines as possible I have two views, and one presentation model. The code follows.
Main.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
[code]...
Debugging the application I find that selectedIndex in the presentation model always remains at the default value assigned regardless of which item I selected from the DropDownList. For the sample code above this is -1.How can I bind the selectedIndex in the presentation model such that it is updated appropriately when the selected item DropDownList changes?
I have a viewstack, which contains 3 (at this moment just 1) customcomponents:

I'm using Flash CS4, as3 and adobe air file. I have an application with 3 scenes, first scene to login, second to set up, and third to see an video. The problem is that, when I put a component in the second or third scene, if a change any property in the component inspector, any property it gives me error. So put the component and I change property by code in as3. But I'm doing things with FLVPlayback component, and now before enter the scene gives me error, the solution will be to get the original properties, but I don't remember, I could install other time Flash CS4, but I can do that for any component, better know the solution.
For example, I have an as file who is the class named p.e. MyMainclass, and in the scene3, I put FLVPlayback, who default values it's the last I used (I don't remember default after installation), if any code in as3, it gives me this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.program::MyMainClass/__setProp___id2__scene3_myvideo1_1()
[com.pro gram.MyMainClass::__setProp___id2__scene3_myvideo1_1:7]
I remove this component, I put another one I never used, it doesn't give me error, I change any property in the object inspector, p.e. color, it gives me error, I change to original property again, and then No Error.
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?
View 1 RepliesStarting new thread for this topic as suggested by forum. I have a website which tweens movieclip pages (named home, bio, music, video and contact). Love the effect and trying to keep it. Main timeline contains the main buttons (home_btn, bio_btn, music btn, video_btn, contact_btn). Music page has a XML mp3 player contained in it with button control. Video page has an encoded video with no code.
I need the following:
1 - Music and video to shut off as those pages/movieclips tween off the stage. Gets annoying with them playing especially at the same time
2 - Music player to play correctly. It is not with the new code.
I have the following code. The "Tween Code" is on frame 1 of the main timeline of the movie. The "MP3 code" is on frame 1 of the music movie clip. I am getting the following ERROR message when running my movie. I ran the Debugger as I publish and it points to music.my_channel.stop(); in below code. My thought process on this was that it would reach out to the music movieclip, find my_channel and stop it.

I added a flv into my Scene 1 then i added a new Scene.I just wanted to after finishing the .flv flash go to next scene.but when i added a new scene,and I test my movie,the .flv didnt show and i recieved these errors
[Code]...
This is my code,
stop();
button3.addEventListener(MouseEvent.CLICK, playClick3);
function playClick3(Event:MouseEvent):void {
gotoAndStop(422);
}
On frame 422 there is no code at the moment. I keep getting the error TypeError: Error #1009: Cannot access a property or method of a null object reference.
I am trying to use the scroll pane component and I am having a few teething troubles. I have a scroll pane as a child object of a movie clip which is essentially a 'page', if I display this page it works fine and the scroll pane does too. If I then remove this page from the display list, go to another page and come back by readding it to the display list, I get the following error, even though nothing else has changed:
TypeError: Error #1009: Cannot access a property or method of a null object reference.at fl.containers::ScrollPane/fl.containers:ScrollPane::endDrag()
The scroll pane is still visible and works correctly, but ideally I'd like to stop this error.
Below is my code, and the question is explained after it.

So my problem here is, I'm working on my Adobe Air project, so I decided to code some buttons to be able to navigate. The problem here is that I get a error for trying to do so. Here is my code.

I do not see what is wrong actually, I tried this on a blank non-AIR file, and it worked well.
I have an Array Collection as follows
var myArr:ArrayCollection = new ArrayCollection([
{label: "label1", data: "data1"},

How to set the selected item for myDDL based on an item id(myID)? I tried something like:
selectedIndex = {myArr.getItemIndex(myID)}
Error #1009: Cannot access a property or method of a null object reference.
This is the error I cannot seem to understand. On the stage I have a movie clip, mcTree. It's keyframe is in frame 3143. There is no tween or anything. In frame 3144, I have the following actionscript:
mcTree.gotoAndStop(2);
I publish the movie and I get to frame 3144 then BAM TypeError: Error #1009: Cannot access a property or method of a null object reference.
at 2file_fla::MainTimeline/frame3144()
As you can tell, I'm more than 3000 frames into my animation here and have made it this far using this method, and it has worked.
In the code below, the presentedAlbumIndex is used to control the selectedIndex of the TileList. Item "five" is initially selected. Whenever the button is pressed the first item in the array is deleted, and the presentedAlbumIndex is decremented.
In theory, the selected index should stay with "five" every time the button is clicked (until "five" is itself deleted). It works this way for the first button press. However, on the 2nd button press the highlighting changes to "six" for some reason. Also, the TileList selectedIndex is always one behind.
I tried looking into ListBase and monitoring selectedIndex. It looks like the selectedIndex is updated initially to the correct index, but then it reverts back at some point to the correct index+1. I do not know why it's setting back.
It seems it's due to the fact that I am doing a data provider delete and index change in the same operation.
Is there some function in TileList I could override to keep selectedIndex up to date?

Is there something like selectedIndex for SkinnableDataContainer? It doesn't seem to be one of the available properties.
View 2 RepliesI have a simple button function that changes the selectedIndex on a view stack without using the menu bar component. I call the function from the click property on the button and pass an int as the index I want to jump to. When I had the code on the application MXML file everything worked fine. After moving my actionscript to a separate file, I get access of undefined property errors:
protected function changeView(index:int):void
{
myViewStack.selectedIndex = index;

How do I get the .as file to recognize the myViewStack component? Do I need to reference Main.MXML somewhere in the .as file? Thanks.
Here is the rest of my code:

And finally the .as files with the function in question:

protected function changeView(index:int, myViewStack:ViewStack):void
{
myViewStack.selectedIndex = index;
}

In lee's xml tutorial he uses the list component and the text area component but when he tested the swf he had to select the item befour the text field was populated.
i have set the selectedIndex to 0 but the data still does not load untill an item is selected.
Ok I can't find any doco on this and it's driving me crazy. Anyone know how you specify the default value for the V2 ComboBox component based on the selectedItem when you don't know the selectedIndex? Here's my scenario:
I have a hardcoded combobox called "dd_names" with 50 names in it. I'm returning a dataset into Flash via a SQL query, and onload I need the dd_names dropdown to default to the value of the name returned in the dataset. So if the query returns "Tom" I need the dropdown to default to "Tom."
I tried setting dd_names.selectedItem = "Tom" and dd_names.value = "Tom" and these don't work. The ComboBox just defaults to the first item in the list.However, if I use the selectedIndex property and set dd_names.selectedIndex = 3, the ComboxBox doesn't default to the first item in the list but shows the appropriate item. This doesn't help because I don't know the selectedIndex being returned from the query - I only know the selectedItem. Anyone know how to do this??
I have a DataGrid bound to an XMLConnector and XMLDataSet. The XML data loads fine into the components. However, I cannot get the value of the selected index using: my_datagrid.selectedIndex
The call works fine if you use addItem to populate the grid.
Is there an issue being that the datagrid.selectedIndex parameter is bound to the XML components?
Isn't there a better way to accomplish this?[code]...
All I want to do is make sure that when I update the item that the comboBox is pointing to internally, that it's selectedIndex also update so that the label within the ComboBox reflects the new value.
I've got a combo box in my movie (called news_selector), whenever the selection of the combo box changes, I want to do something. Here's my code for the combobox so far...
Code:
on(change)
{
trace("News feed changed to: " +news_selector.selectedIndex);[code].....
The problem is that the news_selector.selectedIndex bit is showing as undefined in the debug window, and thusly the if/else statements are ignored completely.
