      Description

      Trying to use a h:selectOneRadio to select one of two values for an enum and it fails, throwing a NullPointerException. No explicit converter is in use so (from debugging) it appears to be using the default EnumConverter.

      Code snippets in question are as follows:

      testLovs.xhtml:

      <h:panelGrid columns="1">

      Simple radio button with constant string values
      <h:selectOneRadio id="l1" value="#

      {testLovsBean.l1}

      ">
      <f:selectItem itemValue="A" itemLabel="labelA"/>
      <f:selectItem itemValue="B" itemLabel="labelB"/>
      </h:selectOneRadio>
      <h:outputText id="l1Str" value="l1: #

      {testLovBean.l1AsString}

      "/>

      <p:separator/>

      Radio button for enum
      <h:selectOneRadio id="l2" value="#

      {testLovsBean.l2}

      ">
      <f:selectItem itemValue="#

      {VALUEA}

      " itemLabel="labelA"/>
      <f:selectItem itemValue="#

      {VALUEB}

      " itemLabel="labelB"/>
      </h:selectOneRadio>
      <h:outputText id="l2Str" value="l2: #

      {testLovBean.l2AsString}

      "/>

      <p:separator/>

      <p:commandButton id="commitCommand"
      action="#

      {testLovsBean.commitAction}

      "
      value="Submit"
      ajax="false"/>

      TestLovsBean.java:

      package tn.view.bean.test;

      import org.springframework.context.annotation.Scope;
      import org.springframework.stereotype.Component;

      import tn.view.util.FacesUtils;

      /**

      • Class used for testing date controls
        */
        @Component
        @Scope("request")
        public class TestLovsBean
        {
        public TestLovsBean()
        {
        }

      public String getL1()

      { return _l1; }

      public void setL1(String l1)
      { _l1 = l1; }

      public String getL1AsString()
      { return _l1; }

      public TestEnum getL2()

      { return _l2; }

      public void setL2(TestEnum l2)

      { _l2 = l2; }

      public String commitAction()

      { System.out.println("commitAction invoked"); FacesUtils.addInfoMessage("L1: " + _l1); FacesUtils.addInfoMessage("L2: " + _l2); return null; }

      private String _l1;
      private TestEnum _l2;
      }

      TestEnum.java:

      package tn.view.bean.test;

      public enum TestEnum

      { VALUEA, VALUEB, }
