It is afaik possible by passing the Object in as a parameter (or field) and in the expression cast it to the correct class.

 

e.g. ((Employee)$P{EmployeeObject}).getName()

 

On a side note, what I'd really like is the possibility to easily use bean properties, instead of casting custom objects in expressions or defining all parameters and fields.

 

Also, being able to use more than one detail field (as opposed to using subreports) would in my opinion greatly improve the ease of use of JR.

Ah, never mind that side note. I completely forgot that it is entirely possible to use bean properties by using reflection in the data source or similar approach. I am too stuck in the legacy framework I have to use for JRDatasources...

 

But multiple detail fields would rock, instead of using subreports or flattening the data.

 

Also (I just keep going on...), it would be quite nice to be able to 'float' fields horizontally, not just vertically. This could help alot in dealing with dynamic reports. Of course, one could always generate the report (or edit it) using the API.

 

Anyway, I'd like to thank Teodor for a great open source solution. =)
