problem passing data from master report to Subreport

[luulamuse]

 

Hi,

I received a collections of animals in my master report. I added 2 subreports into the master reports.

The first subreport should display only dogs informations and the second subreport should display only cats informations by following the order of the main collections.

I tried 3 differents attempts to get the expected results but none of them have worked!!

1) first attempt

To pass data to each subreport, I did this:

connection type = use a data source expression

data source expression = ((net.sf.jasperreports.engine.data.JRBeanCollectionDataSource)$P{REPORT_DATA_SOURCE}).cloneDataSource()

I created parameters to display details.

In each subreport, all animals are displayed animals (cats and dogs) which is bad.

2) second attempt

To pass data to each subreport, I did this:

connection type = use a data source expression

data source expression = $P{REPORT_DATA_SOURCE})

In each subreport, only the first animal is displayed. Any iteration is done.

Could you please help me. I am new in Jasper report and I don't know how to pass data from master to subreport one element at time.

Thanks a lot.
