Hi,
It's not possible to move your cp variable between containers like
that. When you call addChild the second time. cp is still in the
first containers child list.
As Flex updates the display, it runs over the arrays of children on
the component you remove from and thinks cp is still there, except it
isn't. Hence the RangeError (array index out of bounds).
Every child has a parent attribute that points to it's parent. At
any point during runtime, there can only be one reference here, so you
have to cleanly remove cp from it's old container *before* adding it
to the new one.
Really read this carefully:
http://livedocs.macromedia.com/flex/2/docs/1850.html
Technically, I think Flex should do the clean remove for you
(according to the document above anyway). I have a sneaky feeling
though, that this exception throw is partially to alert the developer
to potential berk-traps in code.
Best of luck,
Ciarán

but I got error with RangeError: Error #2006: The supplied index is out of
bounds. What the reason?
