hi, I am a fresh guy to JasperReport, and have some problem with it. 1. The example crosstabs in JasperReport works correctly, but it will not work after opened jrxml file in IReport and save it without any modify. what is wrong? 2. After I created a new simpliest crosstab in IReport, instead display data, it just displayed a blank rectangle in the report. My question is how to create a simpliest crosstab by IReport? Both version of JasperReport and IReport are 1.2.5 thanks robert.
