Re: [flexcoders] List Component Bug!!
Try to use an bindable ArrayCollection as your dataProvider that uses your array. (see the docs for an example).On 3/28/06, Gordon Smith

I'm not sure why an Array of Objects

does.
However, I do want to point out that
writing
public var a:Array = [ { name:
nueng }, { name: saawng }, { name: saam }
];
will produce smaller and faster code than what
you're doing in initData().

Subject: [flexcoders] List
Component Bug!!
Hello,
I was just converting a project from Beta1
to Beta2 and noticed a problem with all my List components that were bound to
data providers which are collections of custom objects.
The problem is that the List selection
highlight is stuck on the last item in the list. Changing the provider to
be an array collection made up of plain instances of the Object class fixes the
problem. The problem seems to effect anything that uses the List
component (ComboBox, DataGrid…)
Has anyone else seen this and found a
fix? Using plain old Object instances are not an option.
Here is some sample code that shows the
problem.
?xml version=1.0
encoding=utf-8?
mx:Application
xmlns:mx=http://www.adobe.com/2006/mxml xmlns=*
layout=absolute preinitialize=initData()
mx:Script
![CDATA[
[Bindable]
public var a:Array;
private function initData():void {
a = new Array();
var myObj:MyObject = new MyObject();
myObj.name = neung;
a.push(myObj);
var myObj2:MyObject = new MyObject();
myObj2.name = saawng;
a.push(myObj2);
var myObj3:MyObject = new MyObject();
myObj3.name = saam;
a.push(myObj3);
}
]]
/mx:Script
mx:List x=10 y=10 dataProvider={a}
width=200 height=200
labelField=name/mx:List
/mx:Application
//-- MyObject.as -
package {
public class MyObject extends Object {
public var name:String;
}
}

I think that the objects in your dataProvider
must implement the IUID interface for selection to work.

RE: [flexcoders] List Component Bug!!
That seemed to do the trick.
Wonder how many others will get stumped on
that? Seems there should have been some kind of error if your objects dont
implement IUID. Maybe this will be addressed through better docs in the
final release or better yet a run time error.
I would have just chalked that up as a bug
and looked to see if it was fixed in the next release if you didnt
mention it!
Thanks so much for the suggestion!

RE: [flexcoders] List Component Bug!!
My understanding is that you have to
implement IUID if your dataProvider items are a custom class. If they're a
plain Object, I don't think you have to. What's the story, Alex?
