Hello,
I added a simple portal (.war) to my jboss-portal 2.6 DR1 installation - when I visit the portal page, I get:

I've seen this exception a few times in the process of playing around with adding a page and then a portal.
Does the PageNavigationInterceptor process every request? if so, why? also, if so, can you think about disabling this? I don't think I (or everyone else) will necessarily be interested in having a PageNavigationInterceptor process every request and then deal with exceptions due to this component.
Thanks
Thanks
