Ah, I see the problem, I think.  You are assuming that BaseDocTemplate 
will automatically advance to the second PageTemplate when the cover 
page is complete.  Not so.  BaseDocTemplate never changes the 
PageTemplate on its own.  Thus, it's never getting to your second 
template.  YOU need to do the switch when you detect the particular 
conditions for a change.  Take a look at SimpleDocTemplate in 
doctemplate.py.  Notice how it uses handle_pageBegin to switch to the 
second page template.

In fact, you may find that SimpleDocTemplate is a better base for you 
than BaseDocTemplate, unless you expect to need some unusual effects.  
Alternatively, you can append a NextPageTemplage() call in your 
report_story at the point where you want to change templates.
