Remove blank page generated by JasperReports

[mannaii.amira]

I need to remove report pages when it contains nothing.

I have a page that contains blanks, so I want to remove it. I tried everything but the problem persists.

I tried this code:

 

private void removeBlankPage(List<JRPrintPage> pages) {    for (Iterator<JRPrintPage> i = pages.iterator(); i.hasNext(); ) {        JRPrintPage page = i.next();        if (page.getElements().size() == 0)            i.remove();    }}[/code]

But it never reaches the if (page.getElements().size() == 0)because the element exists and it's blank.(size always!=0)

Now I'm trying to write a Print When Expression attribute, so I want to retrieve the preceding text if it's a blank then I'm sure that the page is all blank and in this case I don't print the blank text. So the blank pages disappears

But I can't retrieve the preceding text.

So what do you suggest?
