Hi Niphlod
That's a good idea to test in the shell, where it worked fine.
However, it still doesn't seem to work in the following contexts:
Field('name','string', requires=CLEANUP() )
--or--
db.testtable.fieldstring.requires= CLEANUP()
Maybe it's not meant to be used like that?
Thanks for your help!
