Bruno,
It is somewhat difficult to separate the code from the application. Most of
the content is generated dynamically from database queries and lots of
supporting objects. I have included the code (sorry it isn't exactly short)
that deals directly with iText so you can see the sequence in which calls
are made. At the moment I have commented out the newPage() calls and
inserted chapters instead. The result is the same.
You mentioned that newPage() is ignored if it is called after a blank page.
Is there a simple way to force the current page to be written and closed
before calling newPage()?
Thanks,
Kim

I know newPage() is ignored if you call it after a 'blank' page.
But if you have added something (anything!) to the page newPage()
should not be ignored. Can you post a small (standalone) example
that reproduces the problem?
