Jaspersoft duplicated sub report in detail

[pspjasper]

 

I'm working with TIBCO Jaspersoft® Studio 6.6.0 and my need is to create a report based on a query listing n parent keys. For each key I need 2 subreports based on 2 different queries both filterd by the parent key.

The structure consists in a group based on the key (with pagebreak), in the group I define 2 details and in each detail I add a subreport passing the field key as the corresponding parameters.

When only 1 of the 2 subqueries returns some result the report in correct but when both return the results are rendered twice in the sequence

detail1 detail2 detail1 detail2

I'm not used to work with the xml source code but I add it below hoping it helps finding the problem/error.

Any solution or diffrentapproach will be appreciated.

Isn't it correct, if a query returns 2 detail records for 1 group, the detailed band is repetad twice.

You'll have to add both sub-reports to the group footer.
