Ah, thanks a lot for this, it works.
In my RDB/SQLAlchemy-based application, when a user logs in, his
database-userID is stored into the session. In some forms, I have choices
which are filled with user-related data (e.g. his email addresses). To
retrieve this data from the relational database, I need the ID from the
session.
I'd prefer if the vocabulary had direct access to the request, but it seems
that vocabularies are bound to the content object and not to the view,
whereas the request is only available in the view.
One solution could be to build a view-bound vocabulary, but that's probably
hard to do and may break other things. So this seems like a structural
problem that is not easy to solve.
Best Regards,
Hermann
