JIRA assign button not working

[huangbe]

After creating a JIRA record, there's an "Assign" button available.

But when clicking on it, it goes to the spinning timer, and doesn't do anything else (it doesn't go to the next screen where you can assign the record to someone).

Has anyone else experience this issue?
What is the fix available?

PS: Our JIRA page has plenty of javascript-ing behind it, so I imagine it's more complex than your average JIRA page. But I have removed these javascripts one by one, but the "Assign" button still doesn't work.

Since there is a 90% chance that this is caused by your custom javascripts, check what is being thrown in the logs. In Chrome > Inspect Element >> Console. In Firefox, use Firebug then switch to Console and see what is causing it.

You can also check the JIRA logs if there are errors being thrown during the Assign transition.
