SelectionFields with Int validators don't like no values

Reported by: xentac Owned by: anonymous
Priority: normal Milestone:
Component: TG Widgets Version:
Severity: critical Keywords:


If you create a CheckBoxList? that uses a Int validator (by making sure all the options you pass in have integer values), you'll get an error trying to submit a form with nothing checked.

Apparently, formencode's ForEach? has convert_to_list set, so a blank string is converted to [], and then is passed to the int validator and it doesn't accept it.

I couldn't find an unugly or straigtforward way to fix this... I ended up creating my own validator like this:

self.validator = formencode.ForEach?(convert_to_list=False, if_empty=[]) self.validator.validators = [validators.Int()]

The problem with this is that if there is nothing checked, the variable passed to my method (data, because I'm using the fast data controller) on form submit, doesn't exist.
