Report with repeated textfields doesn't print on page change

[giulio.lasta]

So I have a report with, for every row a repeated textfield, so that it prints 3 on the first, 3 on the second and so on...

The problem that I cannot find a solution for starts on the end of any pages: because it prints the first textbox, the second one and the third are left emty (not printed), and on the next page the first one is left empty, but with the second and the third, it starts printing again normally, to get something like this: 

X X X

X       

    X X

X X X

Does anyone have a vague idea of what jasper is doing here? It would make sense that it did not print the whole last row for lack of space, but there seems to be enoght...

If needed I'll post the sorce code of the jasper model.

Thank you in advance
