isStartNewPage not working

2003-06-04 11:18

Hello,

I am currently writing a report that consists of 9 pages. I have created each page as a seperate subreport and call each of them from a single Master report. In the master report, I use 9 groups with $V{REPORT_COUNT} for the group expression. Each group uses the isStartNewPage="true", attribute. The problem is, that when some of the subreports are empty ("NoPages") I was getting blank pages at the end. Even when all of the reports are non empty I was also getting headers of some subreports on the bottom of other's pages.

Upon further inspection, it appears that something is being inserted into the document for each group, regardless if its Subreport is empty. For example, if reports 1-5 have data, 6 and 7 are empty, and 8 has data, Report 8 starts lower on the page as if something were above it.

Hi,

 

OK, I have another idea.

 

Put isStartNewPage="false" and use minHeightToStartNewPage instead.

This min height should be big enough so that if there is already something on the current page, the next subreport should start on the next one.

 

Setting minHeightToStartNewPage to the

 

pageHeight - topMargin - bottomMargin - pageFooter.height

 

should do the trick.

 

I hope this helps.

Teodor
