[bansri.gor]

I export the main report(Course report) from Jasper studio. And that courseReport Content one subreport (course data).

I added course data in a resource of the main report. course data have two subreports (sub-1 and sub-2). I also Add that sub_1 and sub_2 in the resource content of the main report.

But sub_1 and sub_2 not found error generate.

structure of the report is below.

Main report (CourseReport) ---------(content)---->  subreport (CourseData)

                                                                                 CourseData -------(content)-----> sub1 and sub2 (this is two subreports) .
