Hi to everybody, I'm new to Pentaho but I've succesfully created a report with the Report Designer 1.6, I've published it on the Demo Server 1.6 but no data is shown on the pdf report, I see my headers and title. I'm connecting to an Ingres database. I've che3cked the server's log from the window opened while it's running and I get the following error while fetching data:

11:02:33,930 WARN [Parameters] Parameters: Invalid chunk ignored.
11:02:40,930 ERROR [SQLResultSet] SQLResultSet.ERROR_0001 - [fr_306] Could not obtain rowcount.
com.ingres.gcf.util.SqlEx: Request is not supported.

does anybody have ideas?
