Dynamic Report: Vertically extension within sub-report

Hello,

I want to generate a report and fill it with data of an Object with a variable amount of attributes.

For example, the Object has attribtes A, B and C. But the amount of values for the attributes can vary. So for example I want to generate a report with

Value A

Value B

Value C

Vertically after each other, but it could well be that there are 2 values for B, then I want to have

Value A

Value B1

Value B2

Value C

Is it possible to do somethng like this in jasper without a table? (only TextField). And if yes: how to deal with the overflow problem? I am talking about a sub-report. if there are many values of B, there is an overflow in the main report I guess.

Thanks in advance!
