We have several custom fields, one is the result of a Bugzilla import called External ID. Another is one called Case #. Both of these fields are defined as text less than 255 characters.
The first problem is from the Issues screen when you click on More Criteria and add one of these custom fields and then enter a value it does not work. Instead you always see the error message: The JIRA server could not be contacted. This may be a temporary glitch or the server may be down.. Searching other fields works just fine, it's only the custom fields that cause this issue.
The second problem is that when using the Quick Search feature, these custom fields are not included in the search. Based on JIRA-7686, https://jira.atlassian.com/browse/JRA-7686. When a value that matches external id or case # is searched, it should be returned in the results. Instead, we just simply get no matching issues found.
I've already shut JIRA down, cleared the work directory, and restarted based on another post and that did not fix the issue.
We have gone live with JIRA and transitioned ALL of our users to this system. Currently they are unable to find any issues that they were previously working with as they can not search by the Bugzilla ID (external id) or the support ticket number (Case #).
