bug in form with model including list:reference #192

Closed josejachuf closed 7 years ago

josejachuf commented 7 years ago

@gi0baro, Given this model:

class Foo(Model):
    name = Field()

class Bar(Model):
    name = Field()
    foo = Field('list:reference foos')

We insert some values to Foo.

If we create the form the error occurs:

form = Bar.form()

@josejachuf do you have a complete traceback? On which adapter are you experiencing this?
