i am new to iReport/jasper. I have this simple scenario: I have two fields: recordno & name. Now, I have 3 names in my db with the same recordno: name: John, Mark and Steve. Now, I want to show the 3 names (with parameter of the same recordno value) in just one detail or a group header, however, my output shows the 3 names but in 3 details/group as well. How to prevent this? Or how to group or combine them as one? Expected Result ------DETAIL/GROUP BAND-------JohnMarkSteve-----------end---------------- Unexpected Result:-------DETAIL/GROUP BAND-------John-----------end-----------------------DETAIL/GROUP BAND-------Mark-----------end------------------------DETAIL/GROUP BAND-------Steve-----------end----------------- Please help :'(
