    Seam PDF and IceFaces NPE

    ivan Newbie

      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:
