Calling Activity_feedback in an @api.onchange() causes error.

I want to mark scheduled activities a project task as over if it has been moved to a different stage(stage_id).

Scheduled Activity Creation

def_timesheet_create_task(self, project):
#send notification when task is created
  task = super()._timesheet_create_task(project)
  fornotified_userintask.stage_id.task_create_notified_groups.users:
      task.activity_schedule('mail.mail_activity_data_todo', user_id=notified_user.id)

Scheduled Activity Removal

@api.onchange("stage_id")
def_onchange_stage_id(self):
self.activity_feedback(['mail.mail_activity_data_todo']) # Completes the acitivity but Throws error.

It seems like the error is being triggered because the front-end is trying to read mail.message but fails because the mail.activity is gone due to onchange being run before it.

I managed to figure out the issue as well as find a solution. (sort of, i found a way to bypass the root cause)

Problem

If we unlink the activities in the onchange function, the subsequent call which is made to update the record using write(vals) will fail because for some reason vals will include the now-deleted activity.

Solution

Specific to my use case I was able to move the unlink from the onchange method to the write(self,val) method which I overrode.

defwrite(self, vals):

""" override write function so as to remove and re-attach new scheduled activities """

self.activity_feedback(['mail.mail_activity_data_todo']) #remove automated activities attached to task

super().write(vals)

#Add sheduled activities on the new user group

fornotified_userinself.stage_id.task_create_notified_groups.users:

self.activity_schedule('mail.mail_activity_data_todo', user_id=notified_user.id)

Each time the task is editted(using write). It unlinks the activity via activity_feedback() and creates a new one with the new user group computed from the task.
