Since updating to Enterprise 2013 workflow v188.8.131.52, When I set a variable to a user item property, the three dot button where i would previously have set 'Display Name' is not working. Clicking it does nothing. The browser console reports:
SCRIPT5007: Unable to get property 'selectedIndex' of undefined or null reference
This is impacting us quite seriosuly as we cannot get clean names into our documents.
Yup. Totally annoying.
As this is a bug in the product community can't help here. I did it already but maybe you can push that topic by creating an official ticket at email@example.com.
Could you give me a little more context on this issue you're having? Which browser are you using to attempt this and have you tried other browsers? Are you using Nintex Forms also (if so, which version number)? Have you submitted a ticket to Nintex Support? Maybe add some screen shots of the issue.
Take a look at this post to see if might be of some help: Display name option no longer works
