Hello,

I have tested this Issue with combination of varieties code....
Let's see one by one,
#test-1: I have tested the kanban view with "one2many" and "many2one" field. And it's working fine.
     for ex : In Project >> Task (kanban view).

#test-2: But when I have tested with "many2many". Then face the following Traceback. because In many2many filed return no ids.

So, we should improve this things. That's why I am confirm this issue with low Important.

Thanks for the reporting!

Hello
Amit Bhavsar: I understand your concern, but OpenERP Framework does not allows the groupby filter facility on fields with attribute _classic_write = False as they are not native table fields so groupby clause not possible so message itself is self explanatory(but yes i do agree their is chance of improving message and will be done in future).
Amit Patel: I Understand Issue, but kanban view managed web client and so many2many internal view type kanban has also to be managed by web, same like one2many(e.g. in customers form view, contacts is kanban for Company ).
Let me know If I am missing something, I am shifting the bug to web project.
Thank You.
