Creating Cascade Parameters with Pentaho Report Designer 3.5.

Hi,
Working on the jAPS/Pentaho integration I found  problems such as the use of cascading parameters. I find very useful the following post by Prashant Raju. 
I followed his tutorial and the analysis of the file prtp this allow me to understand how  are structured the files:

• datadefinition.xml, 
• compound-ds.xml,
•  sql-ds.xml
• ...

This allow me to create dynamic forms inside a jAPS showlet(*) and execute  reports.
Thx again Prashant.

(*)A “Showlet” is a pluggable user interface component that displays contents, resources and usable services in a web page.
A showlet engine allows to manage these components in terms of configuration and position in a web page. More info
