It is a joke, every ReportData need a new page.

I have tested it yet in the FPReportdesigner with a new project. I can
add two ReportDatasources on a new report (eg. csv) and add to a report
two Databands and connect every Databand with a datasource. If i press
preview, i see the first data shown and the second is missing.

I thinks this is a issue in fpreport not to handle this correct. With
LazReport i have done this without a problem.
