I tried with another report that was using Fusion Maps and it was fine, so I guess the problem is just with Charts Pro. The strange thing is, when I tried doing a completely new report with iReport 4.2 and Charts Pro, I got no problem whatsoever. Is there some incompatibility between 4.1 (iReport) and 4.2 (JasperReports Server)? Yes, even I faced the same issue. The chart prepared in 4.1 is not working in 4.2. I had to recreate the same chart with slight change. Change: The Display field (inside Chart Pro) must be of string type.
