It's hard to understand what your actual problem is, but for me it appears to
be the above function.
TW (and TG 1) widgets are designed around the concept of singleton instances
of a given widget. They are *not* re-created on the fly within a request.
A usual setup is this (untested):
form_a = TableForm('activity_form', fields=[...])
form_b = TableForm('activity_form', fields=[...other fields...])
def get_activity_form():
if request.params['that_hidden_field_that_tells_us_the_form']
== "form_a":
return form_a
return form_b
And of course in your controllers, you also always only return the various
form instances.
