I'm evaluating the use of the JIRA Database Values Plugin, but I've run into a problem searching for data in these custom fields. When I type in the query using JQL it works correctly and the it shows the matches in my test data.
However if I take that same query and save it as a filter and later reload it, or copy the URL contain the JQL and paste it into a new tab, I get a 500 error and an exception. The exception is:
com.atlassian.jira.util.dbc.Assertions$NullArgumentException: stringValue should not be null!
