Modifying Custom Fields

[Lara Weber]

Hello Atlassian-Team,

I tried to do a workaround like this: https://confluence.atlassian.com/jirakb/populate-a-field-based-on-another-field-s-content-in-jira-server-649921383.html

Somehow it doesn't work as if I get a non stopping loading page in the administration -> Issue Fields -> Custom Fields

Do you have an idea why the code attached doesn´t work?

Thanks for your help.

Regards

Lara Weber
