I've implemented a behavior to set a default Description and mapped to one issue type within a project. I've tried this by adding server side script to the field itself as well as in the initializer script (as shown in screenshot below)
Now, when a user attempts to Create an issue and starts off on the one mapped to a Behaviour to populate the description, to an issuetype that is not mapped, a pop-up notification is received.
Is there a way to disable this?
