Strange behavior with weppy

[josejachuf]

Something strange happens to me and I can not know what is happening. This is with weppy 1.3.4

I have an app with Weppy and Python36. I started a new app copying this directory, but this time I used an VENV with Python37.
In a particular form does not work default_values or process_form associated with onvalidation. I thought it could be for PY37 so I created the Venv with Py36. And the same. When I make Submit I get the form errors in all fields that have default values and those that are in the process_form.

I'm going to the old project and it works fine. For the doubts I deleted the pycache

Any idea where the problem can be?

I found the problem, I had this:

Fields_rw = {...}

Fields with uppercase, must be: fields_rw
