You will need to override the data setter
override public function set data( value:SomeType):void
{
if( value != null)
{
text = data.somePropertyToGetTextFrom;
}
}
This overcomes your timing issue via the nullity check.
I'd mozzy on over to Alex Hurai's blog for some talks on things like this.
Oh, equally as good and mayb emore directed, check out Peter Ent's blog.
He's been running a series on itemRendereres
