title: How to remove blank page in jasper report when using page break
body: <p>I need add page break in sub report A, so that sub report B will start in a new page. And rows in sub report A is not determined. So, sometimes there is a blank page between sub report A and sub report B.</p>
  
  <p>Question is - how to avoid the unwanted blank page? I know there is a 'print when' property for page break, but I can NOT figure out the proper condition.</p>
  
  <p>Could you please give me some help? </p>
