Hi Dan,
Thanks for the tip. I started to do that but then just moved adding
the filter to a seperate method which I called after the parentDoc
does it's addChild. The reason is that the parent doc calls
createChildren when it adds the component to the displayList. In the
buttons case it was trying to validate a 2nd UITextField ( part of the
UIComponents createChildren method) I wrote some more about it at
http://thefactoryfactory.com/wordpress/?p=75 because I was pretty
psyched to get it figured out. In the future I think I'll go the route
of overriding createChildren though, as per your recommendation.
