Subreport within another subreport

[thiagoalgo]

The JasperReport accepts subreport within another subreport?

[slaisne]

of course, and it's work fine

How is the field of a bean of a subreport to another subreport? When you create a field containing a JRDataSource to another subreport happens a ClassCastException because the jasperreport tries to convert String.

I don't understand very well what you tried,

because the objective is to call a subreport

in the same maner like the main report.

If respect this, you can chain subreports.

A field is not a JRDataSource.

I will try to illustrate: I have a report of countries. For each country I have a sub-report of states. Within the sub-report of states I would like to have a sub-report of cities. This is possible? Working with collections of java beans or JRDataSource, as I move the towns of under-report of the sub-states to report for cities?

 

Thanks,

Just use a BeanCollectionDataSource from your current state to call the city subReport with all the Cities that are within that state.

 

So I guess something like "new JRBeanCollectionDataSource($F{State}.getCities())" should work (not sure, code just from mind)

 

Just for example - don't know your beanstructure.
