To add to Ravis post, you can invalidateProperties() on set data() and
do the icon assignment in commitProperites()
Its worth the effort if you have a huge list to be displayed and a
best practice building renderers or for that matter any other custom
components.
override public function set data(value:Object):void{
super.data = value;
_myData = value; // private var
dataChanged = true; // flag
}
override protected function commitProperties():void
{
super.commitProperties();
if( dataChanged )
{
dataChanged = false;
if(_myData .Gender == "Male"){
//male icon
}
else{
//female Icon
}
}
}
