rich:fileUpload is not working
I try to get a rich:fileUpload working in my page but i only get weird exceptions when uploading files. The createTempFiles is set to true and i use JBoss 4.2.2, JSF-RI, Facelets 1.1.14 and Richfaces 3.2.2.CR2.
When i try to update a file the following error occurs in the log:
2008-09-07 19:44:53,905 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/sndbx].[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception java.lang.NullPointerException at org.richfaces.renderkit.FileUploadRendererBase.doDecode(FileUploadRendererBase.java:114) at org.ajax4jsf.renderkit.RendererBase.decode(RendererBase.java:76) at javax.faces.component.UIComponentBase.decode(UIComponentBase.java:764) at javax.faces.component.UIInput.decode(UIInput.java:719) at javax.faces.component.UIComponentBase.processDecodes(UIComponentBase.java:1006) at javax.faces.component.UIInput.processDecodes(UIInput.java:633) at javax.faces.component.UIForm.processDecodes(UIForm.java:203) at org.ajax4jsf.component.AjaxViewRoot$1.invokeContextCallback(AjaxViewRoot.java:392) at org.ajax4jsf.component.AjaxViewRoot.processPhase(AjaxViewRoot.java:238) at org.ajax4jsf.component.AjaxViewRoot.processDecodes(AjaxViewRoot.java:409) at com.sun.faces.lifecycle.ApplyRequestValuesPhase.execute(ApplyRequestValuesPhase.java:101) at com.sun.faces.lifecycle.LifecycleImpl.phase(LifecycleImpl.java:251) at com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:117) at javax.faces.webapp.FacesServlet.service(FacesServlet.java:244) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:177) at org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:267) at org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:376) at org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:507) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:147) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:230) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:179) at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) at java.lang.Thread.run(Thread.java:619)
