Jira suite utilities (FREE)
This free add-on add a lot of validators, conditions and post functions
PostFunction aggiunge il setta il field da un altro field (stesso issue o parent issue)
I used it to copy value from other field (within issue or to sub-tasks)
JIRA Misc Workflow Extensions
This one an add-on that adds lots of features about workflow, in detail post functions.
This plugin is more complete than Jira suite utilities but this one is not free as the previous one
The most important feature offered by this add-on is SumUp Tow dimensional Filter Gadget.
Jire offers a two dimensional gadget but it counts only the number of issue.
This gadget can sum the field you want, so you can for example sum the estimate time of each person on your team.
If you’re using heavily Jira’s workflows or some jira’s integration features you can’t live without it! It’s a must have!
I used it to perform lots of actions during a post function event.
You can do what ever you want because you can write your own logic in a language java alike
