Thanks Matt,
that's what I thought aswell, but after playing the "filter lottery" it
turned out to be sitemesh.
As it appears in sitemesh 2.2.1, the PageFilter class has this snippet of
code:
// force creation of the session now because Tomcat 4 had
problems with
// creating sessions after the response had been committed
if (Container.get() == Container.TOMCAT) {
request.getSession(true);
}
I saw that PageFiler is deprecated in 2.4 in favor of SiteMeshFilter, but I
did not get the chance to try and upgrade.
As a workaround I have changed the for the sitemesh filter from "/*" to
"*.jsp" and it seems to work.
Thanks again for your suggestion,
Florian
