    In autoBeansFacelets, I use the ice:inputFile component, but it shows up as a 500 error, because it's throwing an exception. In this case, trying to resolve #{FileBean.name} for the label attribute fails, because there is no FacesContext available to the Facelets EL class LegacyValueBinding. <ice:inputFile id="inputFileComponent" label="#{FileBean.name}" file="#{FileBean.file}" progressListener="#{ProgressBean.progress}"/> javax.faces.el.EvaluationException: null Expression: #{FileBean.name} FacesContext: null at com.sun.facelets.el.LegacyValueBinding.getValue(LegacyValueBinding.java:61) at com.icesoft.faces.component.inputfile.InputFile.getLabel(InputFile.java:251) at com.icesoft.faces.component.inputfile.InputFile.getHtml(InputFile.java:852) at com.icesoft.faces.component.inputfile.FileUploadServlet.sendOutput(FileUploadServlet.java:214) at com.icesoft.faces.component.inputfile.FileUploadServlet.doGet(FileUploadServlet.java:81) at javax.servlet.http.HttpServlet.service(HttpServlet.java:697) 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.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.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.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.sun.facelets.el.ELAdaptor.getELContext(ELAdaptor.java:47) at com.sun.facelets.el.LegacyValueBinding.getValue(LegacyValueBinding.java:55) ... 24 more
