I have a issuetype named Specification.
This issue type has a field named category, that can be: OP1, OP2, OP3.
-------------------
I have another issue-type named BUG.
BUG has a mandatory field that set the SPECIFICATION impacted.
BUG has a field named Category (hide), that I would like to be filled automatic basead on information from the Specification - field Category, using the workflow post-function.
Its necessary to mitigate the possibilite to set the wrong category on BUG.
The Bug Category always need to be the same that the Specification Category informed.
