jasper reports - Blank space at end of page -

background

A sub-location with a column header and an extension section is set to both 20px high.

When the subreport record is displayed on the main report, the expected proxy prints as long as it reaches the bottom of the page.

Then subreport prints the column headers and leaves the blank space, then again the column header and its details start on the new page.

Question

So, will you print the entire subreport on the same page, or the whole report is a new page?
