Show subreport independent of master datasource (master report) in ireport - jasper-reports

Question

Well, i have a Master and a SubReport where in master report i have 2 detail bands. In first detail band i put the "main datasource" (from fillReport), and in detail band 2 i put the subreport (datasource from a param).
My master report is configured to display "All Sections, No Detail" but the problem is that when "main datasource" dont have records the subreport isn't showed. I need show subreport detail independent of content of "main datasource".
How can i do it?
This is my report XML:

SOLUTION
After a lot of research i saw that my concept about "main report" and "subreport" is wrong. When we have a "main report" (associated with a main datasource) the correct is that all "subreport" is directly associated with this. So, i created 3 subreports and pass all datasources like a 'param'. In JasperManagerFillReport i passed a "JREmptyDataSource" to avoid the blank page because "main datasource" don't have any content.

Answer 1

You can try setting WhenNoData property to NoDataSection. Then, in the No Data band add what you want.
Also, check what happens to the subreports when the parameters you send as dataSourceExpression are empty (if they are).
