getting passed datasource items

2005-09-07 13:55

Okay, there is no specific example that does this, so if someone could tell me how to do it I would be grateful.

 

I have a JRBeanCollectionDataSource that is passed to my main report.

Lets say it contains a collection of Department beans.

Each department object contains a collection named "people" of Person beans.

 

Now, if my main report wants to pass the list of Person objects to the subreport, how would I do that?

 

I tried creating a Data Source Expression to pass this info from the main report to the subreport, like this:

new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource((Collection) $F{people})

 

But now I can't figure out how to get the person.firstName, person.lastName items out of each Person bean in the collection that was passed.

 

Help please!
