Making a custom field required based on another custom field value

[Nanda Kishore Reddy.G]

I have 2 custom fields in issue creation page in jira. They are IP Release, IP Recipient. IP Release contains 2 radio buttons with 2 options "Yes", "No". IP Recipient is Multi line text box. My Requirement is if we select "Yes" option from IP Release , then IP Recipient should be changed to "optional" to "mandatory" and if we select "No" option from IP Release , then IP Recipient should be changed to "mandatory" to "optional"

custom fields Id s are

IP Release --> 12431
IP Recipient --> 12435
Yes --> 23832
No --> 23833

I am new to JIRA plugin development. Please help me to solve this one.

Thanks in advance.

Hi, Nanda.

You can possibly do this using the "Behaviours" which is now bundled on the Script Runner: https://marketplace.atlassian.com/plugins/com.onresolve.jira.groovy.groovyrunner

Behaviours add-on does this exactly.

are you developing a plugin or you are trying to find a way to do this?
