Exporting Blank Report Pages - Help!!!

2005-04-18 09:06

Problem: When I go to print PDF or HTML reports to the web browser I get blank pages. I have also tried to print them to the local disk and I still get a blank page. The blank pages only occur when I hand the table model off to jasperreports. I fill a xls spreadsheet manually using poi and the data displays correctly.

 

Details:

Java Version 1.2.4_06

Jboss 3.2.5

Jasperreports-0.6.6

iReports 0.4.1 (to produce .jrxml)

 

Stage 1:

Select a Report.

 

Stage 2:

User selects criteria for the report.

 

Stage 3:

Generate a TableModel of the data, load the report, filter the report based upon selection criteria, compile the report, validate, and fill report.

 

Stage 4:

Preview report in the following formats: HTML, PDF, XLS.

 

Everything works fine if I run the application under the debugger, which is even more strange.

I found that I was not using whenNoDataType="AllSectionsNoDetail", in my .jrxml, however data is still not being filled in. When I debug through the jasperreports code I do get rows of data, otherwise I do not. Any thoughts????
