Does anyone managed well the issue of subreports?

[gechenique]

Hello Forum People!

I have a problem with JasperReports, and is as follows:

The master report does not display a subreport, without sending any error message or anything. Moreover, the part where the data should appear underreporting is "reserved" but blank.

The master report is a common report, which brings data correctly using a standard SQL query.

The report that incrustaría in the master report, ie underreporting comes from a JRResultSetDataSource.

If I send both files to PDF, print each data well, but when I insert the subreport into the master did not see anything.

I would appreciate any help immensely.

Greetings!
