Hi,I'm not properly able with english...

My english is too scholastic , my iReport version is old (2.0) and also in Italian language...

Anyway I try to help you...

 I met in this period  your same issue and i solved with theese following steps.

First of all we have to know that datasources are "consumable" objects, so we can use them only once a time.

This is important ,for example,when we must to print multiple report  in different formats.

I think  that your problem depends by this matter, but I'm a newbe and I'm not sure.

1- I have set  theese subrpt properties (in the main rpt  => rightclick on subrpt icon):

"new JRBeanCollectionDataSource($F{fieldSubDataSource})"  => Expression of data source (nb: note that is not a param, is a field).

 "net.sf.jasperreports.engine.JasperReport" =>  Class of SubReport.

$P{<nameOfYourSubRptJasper>} => Expression of your subRpt passed like a param.

 2- I have declared in my JavaBean another attribute called "private Collection fieldSubDataSource" (with naturally get and set methods).

3- in the main rpt i have added a field (called fieldSubDataSource with type java.util.Collection)  that I have set in my java app with a Collection object (that returned an array list containing the resulset that represents my subrpt data source) when i have filled all the other main rpt fields trough the resultset.

Resume:

In this way i've passed the subrpt like a param and the subrpt data source like a field of the main rpt and all works perfectly.

hope to help you bye.

I was trying to fill my reports with map AND bean all over the time --> no success!

But with the "trick" to add the bean to the hashmap it worked straightaway =)

[Timbo2013]

I did it^^

Filling a report with hashmap "and bean" - though the bean has been added to the hashmap:

yes: [...].fillReport(report, hashMap, new JREmptyDataSource());

no: [...].fillReport(report, hashMap, beanDataSource);

 

I'll write down my experiences for me and if a tutorial is still wanted I could try to translate it (from German to English^^)...!?
