Validators work even without widgets... Take a look here: [1]
Anyway, if you don't want to use validators, here's a handy function
for your use case:
----------------------
def ensure_sequence(obj):
"""
Adapted from turbogears.util.ensure_sequence.
"""
if obj is None:
return []
elif isSequenceType(obj) and not isinstance(obj, basestring):
return obj
else:
return [obj]
----------------------
This way you can also do:
for x in ensure_sequence(unkwnow_object_type):
... do something with x
Cheers,
