hi guys. i was reading flex3 for dummies page 221 on containers and it gave an
example of adding childen using actionscript. it worked fine. but i thought
about adding a removeChild function. but it doesnt seem to be working. can
someone tell me why?
i apologize if this is a stupid mistake.
You are trying to remove a child that has never been added. In your
addCheckBox function you are creating a new CheckBox and then adding it
which is fine but then in your removeCheckBox function you are again
creating a brand new CheckBox and trying to remove it. This will not work
because the new

All works fine until one click
inadvertently goes faster than the transition...
then I get an already parented error on the addchild...
To explain better:

and viceversa waiting the transition

The stack trace follows.
I'm curious as to how addChild() can be throwing a range error, when
it's clearly determining the range itself. Is it that the component is
somehow not ready to accept children or something?
Thanks,

Is there any available hacks using _internal or something so that

Yargh.
Well, I believe TextField's are leaf nodes, meaning they can't have
children. Also, if you'll look at the Object Heirarchy, there's no
DisplayObjectContainer in there -- so I doubt you're going to get much
