JasperReports: Problem printing an 1 to n relation

Hi,
I´m a bit in trouble while trying to print an 1 to n relation with jasperreports. What I want to print is just a simple bill which includes 3 tables: customer, bill, positions having the following relations customer to bill 1 to n, bill to positions 1 to n. To access the reports I´m using the classes from the jasper demo from wocode.com. These classes require an NSArray as parameter containing the data to be printed. So I take the displayed bill put it into a new NSArray and pass it over. But I can´t figure out how the field parameter in the report have to look like. Printing data directly from bill object is no problem (just fieldName) also printing customer fields work fine (customer.fieldName) but I can´t bring the positions to work for me which are stored inside a NSArray. I´ve tried a dozen ways relation.fieldName to get them go but no way. Best I can get is a NSKeyValueCoding$UnknownKeyExpression <fieldName>. Any help would be welcome.


Best regards,
