i'm trying to add subreport to report.

I have setted connection type to "use a connection expression" and the expression is $P{REPORT\_CONNECTION}.
My subreport contains a simple query and some static text, when i test it all works good, but when i test mainreport the subreport does not appear.

I have some static text in subreport, this one should be display always, isn't true? But i can't see it...

During compilation i have no errors, and subreport path seems correct becouse a message say "subreport.jrxml already compiled.".

What can i do?

Thanks.
