Thanks James! I have solved the problem, but could have never done it
without you!!! I will describe the problem if anybody else ever has the
same problem.
The problem is in my widgets render function, this line:
if value is None:
value = []
else:
value = TemplateEventMeta.WEEKDAYS.get_selected_values(value)
On my dev server it correctly translates for example 7, to [1,2,4].
But on my production server it does not! I found out by send out a mail
with the values :)
Where BitChoices.get_selected_values() is :
def get_selected_values(self, selection):
""" Return a list of values for the given selection, or empty is
there is no selection or empty selection """
if selection and isinstance(selection, int):
return [b for b, v in self._choices if b & selection]
elif isinstance(selection, list):
return selection
else:
return []
When I got the mail messages I found out the L next to the integers, which
means that python uses a long instead of integers. The
isinstance(selection, int) therefore always gave a False!!! Now I fixed the
check to also check for long and it works :):):) so happy!
Thank you once more!
