I was using SQLite in this case.  It turns out the error wasn't SQL at 
all, I had a select() call happening on the model after it was shown in 
the form, so the mapper's currentIndex() was reset to -1.  Once I 
eliminated that, things worked fine.

Situations like this highlight my one major gripe about Qt: the way it 
so often silently fails instead of throwing exceptions. Guess that's 
just a C++ thing?
