subreports showing headers but no details

2004-05-16 08:54

Hi all,

 

I have 1 master report containing 2 subreports. Both subreports display a TableModel content (using JRTableModelDataSource). When previewed (JasperViewer) individually, both subs display correctly. But when previewing the master report, I get as many report pages as table rows, all of them displaying the table headers but not its contents.

I'm filling each subreport first and then passing them to the master report as parameters.

 

Why it happens?

Don't try to fill both SubReports before filling the MasterReport.

 

Try this:

 

1.) Load SubReport1 from XML/InputStream

2.) Compile SubReport1 to JasperReport-Object

3.) Load SubReport2 from XML/InputStream

4.) Compile SubReport2 to JasperReport-Object

5.) Create Datasource(s) for the SubReports and create JRDataSource-Object(s) for it

6.) Put both compiled JasperReport-Objects into a master-parameter-map

7.) Put the DataSource(s) also in the master-parameter-map

8.) load the MasterReport from XML/InputStream

9.) Compile the MasterReport to JasperReport-Object

10.) Fill the MasterReport with Master-JasperReport-Object, master-parameter-map and DataBaseConnection (or MasterDataSource).

 

... and voilá©t should work!

Thanks c-box, it did work as expected.

I had another problem though. Please check the post 'Subreports overlapping'
