Problems with IntervalRenderer and PhaseListener
Hi,
I tried to build a page with a clock.
When I call the page, the clock is rendered, but after the first update after the renderer interval of 5 seconds I get a PhaseListener Exception:
10:48:02,125 INFO [ClockBean] setRenderManager 10:48:02,125 INFO [RenderHub] scheduled render service created: core pool size : 5 10:48:02,140 INFO [ClockBean] getServerTime 10:48:07,140 INFO [RenderHub] core render service created: core pool size : 10 max pool size : 15 keep alive time: 300000 10:48:07,140 INFO [ClockBean] getState = com.icesoft.faces.webapp.xmlhttp.PersistentFacesState@14418746[com.icesoft.faces.context.BridgeFacesContext@531e15] 10:48:07,140 ERROR [PhaseListenerManager] Exception in PhaseListener RENDER_RESPONSE(6) beforePhase. java.lang.NullPointerException at org.jboss.seam.util.Parameters.convertMultiValueRequestParameter(Parameters.java:48) at org.jboss.seam.pdf.DocumentStorePhaseListener.beforePhase(DocumentStorePhaseListener.java:32) at org.apache.myfaces.lifecycle.PhaseListenerManager.informPhaseListenersBefore(PhaseListenerManager.java:70) at org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:373) at com.icesoft.faces.webapp.xmlhttp.PersistentFacesState.render(PersistentFacesState.java:180) at com.icesoft.faces.async.render.RunnableRender.run(RunnableRender.java:89) at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:650) at edu.emory.mathcs.backport.java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:675) at java.lang.Thread.run(Thread.java:595) 10:48:07,140 INFO [ClockBean] renderingException fatal render failure for viewNumber 1
Because i wondered why a method from org.jboss.seam.pdf.DocumentStorePhaseListener is called, I removed the jboss-seam-pdf.jar from clocktest.ear\clocktest.war\WEB-INF\lib. After this I get the following output:
