Hello everyone!

I have been having an error in the res.users view when I created a new security group. 

Instead of a form divided by goup categories i was getting a-kinda tree view of groups only. 

If anybody had this problem I found that there is a method that calculated the category groups so that makes the res.users form to look 'normal' again. 

groups = self.env['res.groups']

groups._update_user_groups_view()

self.env.cr.commit()

That way the view gets by category again

it might be helpful to somebody,

greetings
