How to disable an issue operation for a single project?

[Matteo Laracca]

I am attempting to disable the default "assign" operation in issue view and replace it with my own "assign" transition. How can I Hide or disable the default assign button using the issue operations plugin without effecting all projects?

To disable the default assign button in the issues operation plugin go to -> Manage Apps -> Manage Apps -> Drop down "System" -> Scroll down to Issues Operation Plugin -> "37 of 37 modules enabled" -> Disable View Issue Ops Bar Assign Link

Hello @Matteo Laracca , disabling modules will affect everyone on your instance. So don't do that. However, if you have scriptrunner installed on your instance you can achieve this by using the behaviours functionality.
