Looks like the way you were using it before wasn't supposed to work but did
due to a bug. The purpose of the "record" argument is to enable a database
record to be updated, and so it is expected that the record will have an
"id" field (or a set of fields serving as a primary key). It appears you
are instead using the "record" argument as a way of pre-filling the form
with a set of previously used values. In that case, you should add a dummy
"id" field to session.mydata (it shouldn't matter what value you assign to
it, as it doesn't refer to a real record). Alternatively, you could use the
values in session.mydata to set default values in the SQLFORM.factory
fields.
