I kept on testing BIRT flexible reports. When I generate a report like this:
select „Choose report topic: example“,
enter the name e.g. „myexample“ plus a description,
click „send“ and download the generated report.
The downloaded myexample.rptdesign has no layout and the Data Set includes
all the fields in the entity definition for entity-name="Example" in
\plugins\example\entitydef\entitymodel.xml.
I can drag a new table into the main window and specify „Data Set“ as the
Data Set. Then I can select exampleId, exampleTypeId and exampleName from
the list of fields. If I save this report design then and upload it, it will
show the report result as provided in the example at the main button.
This works but it is not mentioned as the procedure to use in the online
documentation. I expected that the downloaded file includes a layout which
the master would provide.
