[web2py] IS_IN_DB(..., multiple=True)

[Rob]

I had an existing table defined and just added "multiple=True" to the
IS_IN_DB statement because I want to convert it from a '1 to 1' to a
'1 to many'.  So, I had some data in the DB before I set
'multiple=True'.

(btw, is there a bug tracker setup so I don't have to spam the group
with reports?)

I got this traceback:
