Subreport empty when run from master


hanlie

Recommended Posts

I know this is a common problem, but I can't see the error in my code and I was hoping someone here could help me. The master report (DateMsisdnMasterReport) should get an MSISDN from the database and then pass it to the subreport (DateMsisdnSubReport). The subreport must then retrieve all the dates of entries in the database for this MSISDN.

 

When I run the subreport by itself and manually pass it an MSISDN, it works perfectly. BUT... as soon as I try to run the subreport from the master report, I get a report with the text "null" where the records should be.

 

Both reports are in the directory

Code:
c:javajaspertemplates on my computer and I made sure that I compiled the subreport to a .jasper file before I tried to print the master report.

 

My master report is here:
