[TurboGears] proper way to instantiate a widget with a specific set of data

[Jeremy Jones]

I have a TableForm with a bunch of TextFields (and other stuff...).  I'm 
trying to use it as the C and U prongs of the CRUD pitchfork.  I've got 
create working well.  But how do I instantiate the TableForm and pass 
it, say, a dict, and have it update the TextFields (and other stuff...) 
with the data in the dict?  this_table_form.input(some_dict) didn't 
work.  this_table_form.insert(input_values=some_dict) didn't work, 
either.  I tried mucking about in the fastdata source, but couldn't 
figure out how it's being done there.  Any tips would be greatly 
appreciated.

Thanks,
