Crosstab and data source

2006-05-30 04:34

I'm trying using crosstab + JRDatasource.. But Iam having problem's with this... I'am making a collection with my beans.. but when I export to PDF, it doesn't show the first element of my collection.. If I put "null" like the first element of the arrayList so, all elements are show in the PDF

 

Somebody have any solution ?!?!

 

 

Thank's a lot...

Hi,

 

I think you are passing the REPORT_DATA_SOURCE as the data source for the crosstab too, which of course its wrong because the report itself starts to iterate through it and consumes the first line before passing it to the crosstab.

You should reconsider your report design and make sure the report has its own data source to iterate through and does not interfere with what you want to pass as data source to your crosstab.

 

I hope this helps.
