All, I
am trying to create a component that has two list with a couple of buttons
between the two list to allow the user to move items between the two
list. Pretty standard type of control. The problem that I am having
is that I want to be able to have a base control that handles the moving of the
items between the two lists. But I want the child instances to be able to
control the labelFunction for each list in the component. But whenever I
assign anything to that function the compiler says only functions in document
are allowed. I am not sure how to expose a function reference to child
objects. I tried over riding the function in a child and that didn’t
seem to work. I am trying to do this in mxml instead of action script. Here
is the source for the control. Thanks Jeff <?xml version="1.0" encoding="utf-8"?> <!-- selector.mxml --> <mx:HBox xmlns:mx="http://www.macromedia.com/2003/mxml" width="100%" height="100%" horizontalAlign="center" vScrollPolicy="off"
