Exception When masterreport has multiple subreport

[me_vsoundar]

Hello,

             I have used jasper reports in struts2 framework.

Consider, I have a master Report called "Master.jrxml" with multiple subreports. I placed all the subreports one - by - one inside the detail part. I used a DAOlist(dataSource) for filling the jasper. It works fine until 5 subreports. If i add one subreport and run, it throws some exception like index 0 size 0... ( i added the error below this msg).

But if i put one sub report per one detail  then it works fine. Is this is the correct solution for the problem? (creating a new detail band for every subreport?).
