How to hide a transition after executed once.

Rafal_Poplawski

I have transition which go from A to A ( A -> A). This transition generate some Attachments and I don't want people to be able to generate them more than one time. Is there any way besides creating a custom field and manipulating it, to do this? Because these solution is ugly for long maintenance.

I guess if you can say from the attachment's name/format that it was automatically generated, you can check for it in a condition (scriptrunner is able to do it, for example, and other script plugins might be as well)
