Update:
Using a for each loop shows me even the right value, but it's type is lost.
override public function set data(value:Object):void {
trace(describeType(value));
for each(var a:* in value) {
trace(a)
}
if (this._item == value) {
return;
}
super.data = value;
if (value is IPlayListItem) {
this._item = IPlayListItem(value);
}
this.dispatchEvent(new
FlexEvent(FlexEvent.DATA_CHANGE));
}
-> the condition value is IPLayListItem is actually never true.
Best regards
