Hello,

I'm currently using Odoo 12.0+e-20181025. At the moment I'm using the Helpdesk module and have been trying to modify it so that it can't be edited after it reached a certain stage. While my team managed to make it so that it can't change stage after reaching a certain stage, we realized that it can still be edited and then saved.

Is there a way to make it so that the edit/save button become invisible or at least unclickable when the ticket had reached a certain stage in the flow?

Thanks for reading and for the help.
