Dear Product Developers, I have a problem with z3c.form, as it cannot
seem to find the widget for my form.
This error is generated when i visit /@@topics_edit -- relevant code
is below the error... any help would
be greatly appreciated. It seems like something simple. No, there is
no code for storing or retrieving the
data to be edited yet, but I think the form should still display.
