I played a bit more with my script ... and it seems that the magical 
goodness of Og redefining tables doesn't work for sqlite ... so, when I 
blew away the sample database, it recreated things and it seems to work now.

I think you should add some kind of an easy to read error message that 
the class definitions don't match up with the database model, and that 
the database model is not alterable ( as easily ) in sqlite

Anyways, thanks for your help.

Oh, also, I was trying to follow the example where you use User[ 'value 
from name field' ] and it doesn't seem to like that ... yet another 
incompatibility with sqlite?

Thanks again.
