Error: "Must provide one of _form or _meta" with mongodb example

[logsoft]

i was not able get an Collection hoocked to superadmin and tested the /examples/mongodb/simple.py but got the same error when trying to create or edit : "Must provide one of _form or _meta"
it seems to happen on collections/documents with linked content. not on single documents like "user"
reproducable on my machines with the plain /examples/mongodb/simple.py script

flask and extensions on latest pip packages

Yup, WTForms >= 2.0 aren't supported yet. Perhaps we can close this issue now to not keep duplicates around?
