Hi.. I have good news for you.. I can solve my problem.. So, i'm going to share my solution with you. I had to show two subreports, that show me 15 records per page of each one. First, I create a group in the subreport, in the group expression I define this: Code:new Boolean($V{dec2_COUNT}.equals(new Integer(20)))//where dec2_count is the variable that the ireport create for a group.. then i put both subreports in the detail band, with the width and height of one pixel each one.. =) all that's all.. in the first subreport you have to select "fix to the top" and in the second report you select "float".
