Hi,

 

You did not post the entire stack trace, so we cannot tell from where it is actually raised. You must be doing something with that parameter in the report, and that would be the cause. You use it in some other expressions.

Post the entire JRXML.

 

Thanks,

Hi,

 

If you don't post the JRXML, we cannot help you. If you say you are sure about what you are doing, then I'm sure you cand find the problem yourself.

 

Thanks,

I thought your problem was with a cast exception when you pass a list parameter.

Now you tell me you have a different problem? Why don't you create a new thread for that????

And this JRXML you posted... what should I do with it? Where is this "li" parameter of type java.util.List that you said you have??

If you mess up the forum postings like this... no wonder the reports are not working...

 

Thanks,

Teodor
