Grappelli Related Generic Fields Compatibility

[uaimax]

Hi! Sorry if it's a dummy question, but I can't use "related_lookup_fields" of grappelli with treemenus.

When I click on magnify icon the pop-up uses a wrong url.

Screenshots of an example:

http://awesomescreenshot.com/0fazpaia0

Sends to http://localhost:8000/admin/treemenus/menu/engine/article/?t=id&pop=1 but the correct link would be http://localhost:8000/admin/engine/article/?t=id&pop=1

Thx!
Regards,
Max
