I need to update a Jira Issue's Priority and assignee based upon business logic. This needs to be done right after create and done automatically.
For example, if issue field A = 1 and issue field B = 3 then set Priority to Trivial. If Platform = iOS then assign to the iOS developer. The logic table for updating Priority has about 7 elements (Customer, Platform, Requestor, Component, etc.)
From my research it seems that a Listener, Jelly, or a scripting plug-in would work. Any ideas on how to do this within the current workfow tool would be great. Otherwise, I need my instance modified.
