Hi all, I'm using a report made of 4 subreports. All is fine if the subreports have data. My problem is when one of the subreport has no data in it, all the next subreports have no data either (even if they should have). Just switching the empty subreport in the last position makes the other ones appears correctly. I'm pretty sure I'm missing a parameter in the main report but I don't know which one. Could someone help me one this please ? Here is the code of the main report : <?xml version="1.0" encoding="UTF-8"?><!-- Created with Jaspersoft Studio version 5.6.2.final using JasperReports Library version 5.6.1 --><!--

it's been inserted in a xml code section though (I'll try to change that)
