Seam PDF and IceFaces NPE
I have problems integrating Seam-PDF with IceFaces.
I have the following test scenario:
jboss-seam-1.2.1-GA
project: itext example from seam 1.2.1GA
jboss-as-4.0.5-ejb3
Starting with a working project from the examples I added Icefaces jars and modified the web.xml accordingly. I tested with iceFaces 1.5.3 and 1.6.0DR4. with and without jsf-facelets.jar and i get the following exception:
