I can't get a form to validate and for the life of me, can't figure
out why.
I keep getting an error on the topics. Regardless of how many I
choose, it returns an "Enter a list of values." error. It looks like
even though the form returns a list of topics, it doesn't send the
list to the validator, just a single value.
I've also tried converting the topics bit to a MutlipleChoiceField,
but didnt' have any mroe luck with it.
Any suggestions of where to look are much appreciated. Thanks,
dan
