Yeah;
I a using latest trunk;
I will try again.
Perhaps I am making a mistake? like I said it worked with Bruno's
suggestion.

Hmm, it works fine for me. Did you do:
{{if 'form' in response._vars:}}
{{=form}}
{{pass}}
For me, if my controller returns dict(..., form=some_form_object), the
form gets displayed, but if the dict does not include a 'form' key,
nothing is displayed, and there is no error.

Strange this did not work.
But Bruno's solution did.
if 'form' in globals():
{{= form }}

If you want to test specifically whether 'form' was returned in
the dict of the controller action (as opposed to possibly being
defined in a model file), you can also do:
{{if 'form' in response._vars:}}

I am wondering why if I dont return anything in my dict
and in my view
{{if form:}}
{{= form }}
{{pass}}
I get an exception.

I want to be able to check if a key is there before I use it.
Thanks.
