 Subject: [flexcoders] List dataProvider issue (don't wanna say bug!!)
 
 I broke this issue down to a VERY simple example and the problem is
 still there.
 When I create an ArrayCollection of items and assign it to the data
 provider of a List. The very first item in the list cannot be
 selected. Very Weird. If I change my collection of custom VO objects
 to generic {} type objects, it works fine. I've tried messing with the
 [Bindable] meta tag to no avail. Anyone come across anything like
 this?? I don't want to use generic objects as a work around.

RE: [flexcoders] Re: List dataProvider issue

OK, but we recommend implementing IUID because non-dynamic objects are
larger and slower than dynamic ones. It could be as simple as

public class ItemVO {
 public var name : String;
 public var type : String;
 public function get uid():String { return name; }
 public function set uid(value:String):void { name = value; }
}

if the name field uniquely identifies an item.

And note the hard requirement for this will go away in beta 3 though the
best practice of implementing IUID remains.
