Report working with iReport but JR throw an error

[bob007]

Hi,

 

I make my reports programmatically and I got this exception on compilation with JasperReports  BUT when I export my report in .jrxml to try it with IReports its working (with a queryString).

The error seem to occur because the compiler try to cast my report variable ($V{totalPriorite}) from Integer to String.

 

What can cause this error ?

 

I join the output .jrxml.

 

Thank you,

Philippe

Ok its solved,

 

It was a stupid error.

I declared the wrong class for the using of the variable then the compiler was trying to cast Integer to Sring.

 

its working now

 

Regards,

Philippe
