[Bug 1264950] [NEW] 7.0: stock_picking.action_cancel can cause RuntimeError: maximum recursion depth exceeded

 

Public bug reported:

During the testing of an addon for a customer, in which I call
cancel_assign on stock pickings I came across the exception for which a
stack trace is attached to this bug report.

It looks like writing to the state attribute of the picking generates
call to trg_write, even if the value written is the same as the existing
value. So a possible fix would be to check for the state of the picking
and only issue a call to write if the value is to be modified.
