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/00001850.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.
