When you are rendering an existing data set, do you pass only the id or
use kw ?
If there are no kw params, you should not go through the if kw: part and
render the form... But if you use kw you will trigger the
get_errors(...) and eventually render the form too with tg_errors added
to the return dict.
Are you sure the issue is not in your form definition or the "params"
you pass when in the last "else: # no data posted..." I would look there
first.
