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: | ERROR [D2DFaceletViewHandler] Problem in renderResponse: java.lang.NullPointerException | java.lang.RuntimeException: java.lang.NullPointerException | at org.jboss.seam.pdf.ui.UIDocument.processHeaders(UIDocument.java:265) | at org.jboss.seam.pdf.ui.UIDocument.encodeBegin(UIDocument.java:222) | at com.icesoft.faces.application.D2DViewHandler.renderResponse(D2DViewHandler.java:579) | at com.icesoft.faces.application.D2DViewHandler.renderResponse(D2DViewHandler.java:586) | at com.icesoft.faces.facelets.D2DFaceletViewHandler.renderResponse(D2DFaceletViewHandler.java:276) | at com.icesoft.faces.application.D2DViewHandler.renderView(D2DViewHandler.java:149) | at org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:384) | at com.icesoft.faces.webapp.xmlhttp.PersistentFacesServlet.service(PersistentFacesServlet.java:406) | at javax.servlet.http.HttpServlet.service(HttpServlet.java:810) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:57) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) | at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) | at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) | at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432) | at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) | at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) | at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) | at org.jboss.web.tomcat.tc5.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:156) | at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) | at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) | at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) | at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) | at org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) | at java.lang.Thread.run(Thread.java:595) | Caused by: java.lang.NullPointerException | at com.icesoft.faces.context.DOMResponseWriter.enhanceAndFixDocument(DOMResponseWriter.java:393) | at com.icesoft.faces.context.DOMResponseWriter.writeDOM(DOMResponseWriter.java:313) | at com.icesoft.faces.context.DOMResponseWriter.cloneWithWriter(DOMResponseWriter.java:259) | at org.jboss.seam.pdf.ui.ITextComponent.extractText(ITextComponent.java:210) | at org.jboss.seam.pdf.ui.ITextComponent.encodeChildren(ITextComponent.java:190) | at org.jboss.seam.pdf.ui.ITextComponent.encode(ITextComponent.java:235) | at org.jboss.seam.pdf.ui.ITextComponent.encodeChildren(ITextComponent.java:200) | at org.jboss.seam.pdf.ui.ITextComponent.encode(ITextComponent.java:235) | at org.jboss.seam.pdf.ui.UIDocument.processHeaders(UIDocument.java:263) | ... 31 more | my web.xml: | <?xml version="1.0" ?> | <web-app xmlns="http://java.sun.com/xml/ns/j2ee";
