I'm afraid the sages may all be on sabbatical right now, but hopefully one 
will show up soon.
I wish I was knowledgeable enough to help, but I didn't even realize you 
could add
non-PythonCard components to a Background or a PageBackground, at least 
not without 
mucking about with the event model. Adding a wx.grid component is a pretty 
nifty
thing to do; I had been wishing that PythonCard had a grid component.

Anway, despite my lack of sagely knowledge, here are a few ideas:

Has this grid component ever worked for you in a normal Background, 
outside
the context of a notebook page?

I noticed that you're creating the grid as self.fileGrid rather than 
self.components.fileGrid.
Maybe it's worth a try to put it in self.components.

You could also sprinkle in a few print statements to see if the 
on_initialize is happening
when you think it's happening.
