I wanted to experiment with some visual inheritance. So I have two
classes. One is extends Composite, and the other extends the first
class. I have an AbsolutePanel as a public member of the first class,
but when I'm trying to change it (resize) from window builder in the
second class I get this:
Internal Error
GWT Designer encountered unexpected internal error.
This could be caused by a GWT Designer bug or by a misconfiguration
issue, conflict, partial update, etc.

Could anyone help me with this. Because I don't know whether I did
something wrong, it is a bug or limitation, or if there's any other
solution to this problem? Thanks in advance.
