With all of your suggestions, I have basically got it working. I
store the node as suggested, and I use the getData method.
However, I had to do something which causes me to think that my
ActionScript skills need some help.
In my OpenTree Command I basically have the following:
public function onResult( event : Object ) : Void {
var list1:Array = Array(event.result);
if(list1[0] instanceof TreeNodeVO ) {
// THIS NEVER GETS TRACED
trace("list1[0] is an instance of TreeNodeVO");
}
processTreeNodeVOs( event.result);
}
private function processTreeNodeVOs(list:Array):Void {
if( list[0] instanceof TreeNodeVO ) {
// THIS TRACE DOES EXIST
trace("list[0] is an instance of TreeNodeVO");
}
}
I am not sure why in onResult the typecast and instanceof is different
than calling a method with an Array signature and doing an instanceof.
If anyone has any insight into why that is the case, I would be
interested in hearing what I am doing wrong.
In any event, thank you for your help - I am now off to the next set
of challenges.
