I'm working thru the errors/warnings in migrating a Beta 2 application
to Beta 3.  I've cleared up all the Builder errors but get the
following runtime error (there is no error number):

Error: Cannot add a child that is already parented.
      at mx.states::AddChild/apply()
      at mx.core::UIComponent/::applyState()
      at mx.core::UIComponent/::commitCurrentState()
      at mx.core::UIComponent/mx.core:UIComponent::commitProperties()
      at mx.core::Container/mx.core:Container::commitProperties()
      at mx.core::UIComponent/validateProperties()
      at mx.managers::LayoutManager/::validateProperties()
      at mx.managers::LayoutManager/::doPhasedInstantiation()
      at mx.core::UIComponent/::callLaterDispatcher2()
      at mx.core::UIComponent/::callLaterDispatcher()

Of course everything worked fine in Beta 2.  I've changed all the
"child" properties to "target".  I've commented out every occurrance
of mx:AddChild but still get the error at runtime.

What exactly is this error trying to tell me and how do I go about
fixing it?

Bill
