I'm using JRBeanCollectionDataSource(objects) to pass the data into the report. This works very well. However, if the objects inside have a reference to another object and I would like to print the fields of this referenced object, I didn't found a way up until now. Of course, if the reference would be again a list of objects, I could make it with a subreport. But in this situation it isn't, it is only a simple reference to another object and I would like to print it's values. How could I define the fields of the referenced object within the report?
