Hi all,

I made a module myself inheriting from res.partner but changing the name, so the module creates another table with few fields added.

But after installating this module, I cannot create or duplicate users, because I get this error when saving:

EDIT: The error is happening not only with users (create, duplicate), but with all modules that are related to res.partner. The error is the following one:

MissingError

One of the documents you are trying to access has been deleted, please try again after refreshing.

If I uninstall the module, it's working fine and I can add and duplicate users.

What could it be?
