Hello Jeff, Without going and digging through code, my guess is it's trying to render the template that is exposed for add_finish (which is None since you didn't provide one) which is what is throwing the error.
My solution would be to use the template='enchidna.templates.machine_add" template for add_finish and not expose add_vmware (unless you need this exposed elsewhere), since the only two options for add_finish is a redirect or the machine_add template anyway. Alternatively, you could construct a URL to use the parameters you're passing to add_vmware and pass that through redirect. - Sam Justice On Sun, Feb 8, 2015 at 6:39 PM, <[email protected]> wrote: > Hello all, > > I am a relatively new user of TG2, and came into the project because > changes in our campus environment finally created a problem that could not > be fixed in a TG1/Python 2.4 based web application. > > The problem I've encountered is in a controller that does some silent > processing of a form, checks some values and then forwards the user to a > sub-form to continue adding additional information.
