How to move a report item from one page to the previous. [message #997183]

Hi,

I have a table, each of its row contains an image (its size is as wide and as hight as the page except header and footer) and a grid.

I would like to move that grid up, so it will overlap the image like below
index.php/fa/12878/0/

I do that by setting top margin to the grid -50mm. The problem is, it cant produce PDF report. The PDF is corrupted and there is stacktrace:

If I change the image height so both, the image and the grid are on one page, then it works, but the image is not as high as the page.

How can I do that? Thanks

The only way I can avoid the NPE and thus generating the PDF report is setting this options

renderOption.setOption(PDFRenderOption.PAGE_OVERFLOW, IPDFRenderOption.CLIP_CONTENT);

This works fine but unfortunately only when the table's dataSet contains one row. If there are two or more rows,
they are cutted off instead of creating another pages.

Maybe something like this solution would work for you:

Thanks for your suggestions Michael. But it won't work for me because a background image in Birt has to be embedded or from shared resources. So it has to be static.
And I need that image to be dynamic from a dataSet.
