Jasper Studio 6.4.3 - Report Book not rendering Content when used Javabean datasource

Hi 

I am using Jasper Studio 6.4.3 and creating a report book using java bean as datasource.

If i used direct SQL queries inside report  report book is generated, but when i am used Javabean as datasource - Content, Table Of Contents are empty.

It seems this open issue in jasper. Can you please fix the issue ? 

Thanks & Regards
