I face some interesting problem
this is what I have done.
1. Duplicated purchase user access group under the name: only own documents
2. under recorded rule for purchase order added rule: [('create_uid', '!=', user.id ),('create_uid','=',False)]
3. I changed user1 group from user->user:only own documents and I got expected result, user1 sees only his only docs.
4. I changed user1 group back : user: only own documents -> user, it still shows only his own docs.
5. i changed to manager, again nothing was changed
6. I deleted group user:only own documents, again nothing was changed.
So, any idea what happened, where I have to look for solution?
