Anytime I use query input control (single or multivalue), in prompt window I do not see any values displayed. Options are there, you can select any item, but labels are not visible. You can only guess , which item you are selecting – eventually you will get report, but you don’t know for which parameter value. I have tried different browsers (Chrome, Firefox), different report architecture and different databases (MSSQL,Derby) as source to eliminate possibilty of problem root cause being in external factors.
I am using JasperReports Server CP 6.0.1
