Hi! I am geting an assertion failure while adding wxFrame as parent of a wxPanel obj.  here is the backtrace: http://pastebin.com/ze141PQu

the code for wxWindow is here: https://github.com/abhinav2004/swxTK-java/blob/master/src/java_wxwindow.cpp
wxPanel: https://github.com/abhinav2004/swxTK-java/blob/master/src/java_wxpanel.cpp
wxFrame: https://github.com/abhinav2004/swxTK-java/blob/master/src/java_wxframe.cpp

java_wxframe inherits wxFrame.

Does anyone know how to fix this issue?
