I'm trying to integrate icefaces with a Seam app and am hitting a snag. Has anyone else seen/resolved this. When I hit the front page, or even debug.seam, I get the following java.lang.NullPointerException | com.icesoft.faces.application.D2DViewHandler.calculateRenderKitId(D2DViewHandler.java:696) | com.sun.faces.lifecycle.RestoreViewPhase.isPostback(RestoreViewPhase.java:241) | com.sun.faces.lifecycle.RestoreViewPhase.execute(RestoreViewPhase.java:170) | com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:244) | com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:113) | javax.faces.webapp.FacesServlet.service(FacesServlet.java:244) | org.jboss.seam.servlet.SeamExceptionFilter.doFilter(SeamExceptionFilter.java:46) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) This looks very similar to the issue described here: http://www.icefaces.org/JForum/posts/list/3263.page#15483 The setup is Icefaces 1.5.1, Seam 1.1GA, JSF 1.2. Facelets. I have not yet introduced any icefaces tags to the .xhtml pages When integrating icefaces I used the article here http://support.icesoft.com/jive/servlet/KbServlet/download/623-102-847/Se... and also the icefaces demo that comes bundled with Seam 1.1.GA as examples.
