When a leave allocation is created for an employee i notice that if there are followers tied to that employee it generate an error if you try to Approve See error below:

File "/opt/odoo/addons/mail/models/res_partner.py", line 167, in _notify_by_email
    new_emails, new_recipients_nbr = self._notify_send(fol_values['body'], fol_values['subject'], recipient_template_values['followers'], **base_mail_values)
ValueError: "body" while evaluating
u'holidays_validate()'

 

If i remove the followers i can then approve successfully.

This leaves me with these questions:

• Please what is the correct way to do this?

• Am i suppose to leave the followers or remove them?

• Are emails suppose to fly to the followers?
  

And also what is the effect of adding the followers to an employee when doing leave allocations and request.(Note: It dose not work when you click on Approve button if a follower is tied to employee)
