Multi-page marker

[Pierre-Yves Chauveau <pi...@manpower.fr>]

Hi,
I would like to use a marker that can be retrieved from a different page, ie till I don't get a new title I want the same title rendered in the footer part.
So I used marker and retrieve marker but I get a NPE
If I put retrieve-boundary="page", it works on the first page but on the second page I don't get anything...

Pierre-Yves.

The current implementation can only get markers from the same
page. It's noted somewhere in the documentation distributed
with FOP. It will take some time to get the full spec
implemented.
