Hello,
i added a pivot view on model mail.message and it works very well
But i'm facing a problem because it doesn't work for every user.
For some of them, there is the following message :
"Only administrators are allowed to use grouped read on message model"
If i give admin right to these users, this message disapear but i can't give admin rights to everybody of course.
Is anybody knows how to allowed every user to see my pivot view on mail.message model?
Other thing, i tried to find this message in Odoo to see the condition for its display but never found it, neither in translation nor in code!!!
Thanks in advance
Vincent
