I have created a report in iReports with a simple name parameter, eg agent_namelist as a string with a default and it works fine in iReports. I uploaded that to our jasperserver and the report runs but the pop-up to select the agent name shows a list of blank results. If I click on any result the server does filter for that person and shows the right results but there isn't any way to see who I am selecting as the agent. This happens in IE, Chrome and Firefox. I attached a screenshot, as you can see I have selected someone but I don't know who until I run the report.
I'm not sure if my server was updated recently but the sql queries to both MS SQL and DB2 for LUW work as designed and are showing results now.
