XSL-FO demonstrating the odd page content overflow
I have a scenario where I print mailing labels on the back of each piece of
paper (even pages). When content is too much on page 1, it should overflow
onto page 3 (while mailing labels print on both page 2 and page 4).
ISSUE:
In FOP 1.0 when the content overflows page 1 to flow onto the next ODD page, a
java.lang.NullPointerException is thrown. This functionality did work in FOP
0.95.
Attached a simple XSL-FO to demonstrate this.
Thanks.
