I upgrade 5.0.1 to 5.6. In new version all "Single Value" input control, not mandatory with datatype of Text, when used it always displays a default of "[Null]". In old version the input control was correctly empty. Therefore when the control is used, the user always needs to delete the "[Null]" text or jasper take "[Null]" as value of the parameter. The only solution I found is set the default value as "" (empty string). But haveI to change all my input control after upgrade?!? With more of 250 reports it's a problem..............
