I've configured a custom worklog attribute with the following settings:
Type: DYNAMIC_DROP_DOWN
External URL: http://www.sokolsky.me/test.html (returns the sample JSONP from the tutorial)
However when I try to log time in Tempo the custom attribute is empty. My server logs are also showing that JIRA didn't try to reach my server at all, so I assume the external URL is not the issue here.
Am I missing something in the configuration?
