Hello,

FOP aborts with a NullPointerException when a table consisting of rows each 
having an id spans more than one page. The exception does not happen when the 
table fits on one page or when the id is put on the first cell instead of the 
row.

example fo file: 

<?xml version="1.0" encoding="ISO-8859-1"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";>

bottom="3cm" margin-top="3cm" page-width="21cm" page-height="29.7cm" master-
