aggregation doesn't work

XFabien

Hello,

I have a problem when creating some reports. I created all the reports' elements in the libraries and added them to the reports.
When I used these report element to the reports, the aggregation could not be found when I use the run+render mode.

My birt version is 2.6.2. and the runtime version is the same.
Here is the example batch that I used to run the report and you can use the report below to test it.
Thanks in advance for the help. I appreciate very much all your advises.
