problem displaying multiple nested java.util.lists in subreports

[nstonebraker]

I'm not sure what I'm doing wrong here, so if anyone could point me in the right direction I'd be greatly apppreciative.  I'm running iReports(5.5 I believe) and I have sample data beans + factory jarred and included in iReports classpath.

I'm trying to display multiple nested lists in subreports(eg. company -> employee_list -> phone_list).  The report setup looks like this...

Main (Company info)

• Main details section - Subreport1(company.employee_list)
  • Subreport1 details section - Subreport2(employee.phone_list)
    • Subreport2 Details section - phone number field

I'm passing data to the subreports like this...   new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{employee_list}).  Each subreport is created the details section of its parent, and only the main report has any fields outside of details.

The problem I have is my report is rendering all the phone numbers under the first employee and then the remaining employees are rendered at the end with no phone numbers like this....

Company XYZ

• Bob
  • ​555-1234
  • 555-1236
  • 555-1237
  • 555-1238
  • 555-1239
  • 555-1240
  • ...
• ​Joe
• Susan
• Mike

What am i doing wrong?  I tried puting the employee / phone number fields in various different bands to no avail.  Im sure its probably something trivial
