> 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"/>
