Hello,
By using odoo, I have a problem of deleting a chat application that will generate the deletion of all the other applications of which there is my data, the message:
Odoo Server Error - Validation Error
The operation could not be completed, probably as a result of:
- delete: you are trying to delete a record that other records refer to
- creation / modification: a required field is not correctly filled
[referenced object: mail_message - mail.message]
Thank you I need help.
