[news.eclipse.birt] Dynamic sub-reports

[zareldan@xxxxxxxxx (Manu D.)]

Hello,

I would like to create a report that could be dynamically designed from a 
database. 
I have a list of first level sections and a list of sub-report linked to 
each section, both retrieved from a query. 
Each sub-report is generic and can be used for all first level sections. 
I can't use the drill down function because I generate a PDF document.

My first problem is that I can't link a true subreport template and choose 
what sub-report I would link depending on a parameter.
Then I tried to include all sub-reports ( from external libraries ) in the 
first level table and hide them to display only needed sub-reports. I have 
more than 50 different sub-reports but I only need to display 3 or 4 
sub-reports in each section.
Unfortunately all sub-reports are computed even if they are set to not be 
visible. As I run quite big queries ( ~ 10 minutes each ), it's not 
acceptable to run all sub-reports. 

Here is a sample of what I need :
________________________
Section 1
   - subreport A
   - subreport B
   - subreport C
   - subreport D
________________________
Section 2
   - subreport B
   - subreport D
   - subreport E
   - subreport F
   - subreport G
   - subreport H
   - subreport I
   - subreport J
________________________
Section 3
   - subreport A
   - subreport C
   - subreport E
   - subreport H
   - subreport J
________________________

..

Does anyone have any idea on how to do that ?

Thanks in advance.
