Need to develop some functionality, which technology to use? Event listener/fragment/postfunction?

[Mouna Hammoudi]

I need to develop the following functionlity for the issues of type superfeature. If the issue has components and has fix versions and the components start with WF,EF,... then I need to create a list of subissues of type feature for each of the issue's components as shown in the above diagram. Which technique using scriptrunner should I use? 

I would like all of this to happen after I click on a button so which technology should I use?

• Event listener 
• fragment/REST endpoint 
• Postfuncton/validator

The best way to do this in Jira is to use as much of the standard functionality as possible.

• Create a "super feature" issue type, and configure it differently to the other issue types
• Make the component field mandatory
• Make the fix version field mandatory
• The version has to be in the list of versions, you can't add a version that is not listed

For the rest of the process (all the sub-task stuff), you'll need to use Scriptrunner to create a post-function or listener that can do all of that.
