Wendy Schmitz [http://community.jboss.org/people/wendyschmitz] created the discussion "jbpm-human-task has dependency on jboss-seam -- causing issues with JSF" To view the discussion, visit: http://community.jboss.org/message/641797#641797 -------------------------------------------------------------- I am creating a richfaces web application that will act as the front-end for an embedded jbpm engine. I'm running into the following exception when I launch the first page in the application: 2011-12-15 10:10:51 SeamPhaseListener [WARN] uncaught exception, passing to exception handler java.lang.NullPointerException         at org.jboss.seam.jsf.SeamPhaseListener.raiseEventsAfterPhase(SeamPhaseListener.java:435)         at org.jboss.seam.jsf.SeamPhaseListener.afterPhase(SeamPhaseListener.java:188)         at com.sun.faces.lifecycle.Phase.handleAfterPhase(Phase.java:189)         at com.sun.faces.lifecycle.Phase.doPhase(Phase.java:107)         at com.sun.faces.lifecycle.RestoreViewPhase.doPhase(RestoreViewPhase.java:116)         at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118)         at javax.faces.webapp.FacesServlet.service(FacesServlet.java:409)         at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.j ava:290)         at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206)         at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233)         at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191)         at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127)         at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)         at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109)         at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298)         at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:857)         at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.ja va:588)         at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489)         at java.lang.Thread.run(Thread.java:619) It seems like Seam is invoked when I launch my Richfaces/JSF application, causing it to interfere with the normal JSF processing. It turns out that jbpm-human-task has a dependency on jboss-seam, and when I remove jbpm-human-task from my pom, I no longer have this exception. How can I use jbpm's human task component in my Richfaces/JSF web app without it breaking the app?
