Minor 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="#
">
<f:selectItem itemValue="A" itemLabel="labelA"/>
<f:selectItem itemValue="B" itemLabel="labelB"/>
</h:selectOneRadio>
<h:outputText id="l1Str" value="l1: #
"/>
<p:separator/>
Radio button for enum
<h:selectOneRadio id="l2" value="#
">
<f:selectItem itemValue="#
" itemLabel="labelA"/>
<f:selectItem itemValue="#
" itemLabel="labelB"/>
</h:selectOneRadio>
<h:outputText id="l2Str" value="l2: #
"/>
<p:separator/>
<p:commandButton id="commitCommand"
action="#
"
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,
}
