XRCed and NoteBookPages

Dear wxPython Users

I have a problem with XRCed.
I have created with XRCed a NoteBook that containes 8 pages. Those NoteBookPages are implemented with Panels. I gave a name to each panel.
I have generated then the xrc and python files.

My problem is that some variable (but not all) corresponding those 8 panels are missing in the python file.

Thanks in advance for any idea.
Christophe
