This is on PF 3.0.M3. The facelet is this:

                <p>Now we are testing time zone input </p>

                            <f:selectItem itemValue="AET" />

                                 <!-- about 600 selectItem elements omitted -->
                            <f:selectItem itemValue="WET" />
                            <f:selectItem itemValue="Zulu" />
                        </p:selectOneMenu>
                    </h:panelGrid>
                    
                    <h:commandButton value="Do it" action="#{test.doNothng}" />                                   

                    <br/>
                    Value is: <h:outputText id="ooga" value="#{test.testValue}" />
                </h:form>
            </ui:define>

        </ui:composition>

    </body>
</html>

The test bean's testValue property is a String. When attempting to render the page I get this:

Code: Select all

java.lang.NullPointerException

       (etc)

What broke, me or it?
