Hi,

 

I tried iReport1.1.0 with my existing report, but got the following exception. My report works OK without iReport.

 

Thanks

Compilation running time : 797

Filling report...

Locale: English (United States)

Error filling print...

Hi jyz,

 

Good catch. Can you send me your jrxml so I can see in depth what's the problem?

 

Thanks

 

Giulio
