[#4808] - Main Report parameters can not be pass to the second sub dataset

Hello,
I have a problem. I made a report(Jasper version 3.7.3), wherein a jr:list and a jr:table in it can be found. I want to give up the parameters of the main report to the jr:list and jr:table.
I have set the main report parameters of the jr:list as follows:
picture1.jpg
There weren't any problem with this, I achieved the main parameters inside of the jr:list(BankStatementMonthly) dataset.
The problem was than I wanted to give up it to the jr:table. I have tried as follows:
picture2.jpg
In this case there was nothing in the report parameters map.
I have even tried to give up the parameter map as Parameters and extract so the parameters, but that also didn't run.

I would like to ask your help, it would be very important.

Best regards,
