Correction: error says AttributeError: type object 'team_doctor' has no
attribute 'search'

Ok I read about unbound functions and I was missing the decorator.. now
when I define the search method like this:
@classmethod
def search(self, clause=[('id', '!=', None)], order=[('team', 'ASC')]):
pass
I get the error:
File "............../trytond-3.2.2/trytond/model/fields/one2many.py", line
98, in get
targets = list(chain(*targets))
TypeError: 'NoneType' object is not iterable
which I guess because there isn't bringing any records, but shouldn't just
show an empty list? I have the feeling that I'm doing something really
wrong. In the documentation doesn't say anything about defining that search
function when defining many2many.
