PrimeFaces Poll listener not called

I have a jsf page with a p:poll tag with a listener and an update. The update is called but the listener is not.

I slowly removed sections from the jsf page until I narrowed down the issue to a <f:validateLongRange> tag. If I removed the validate the listener is called but with it in it is not.

The simplified jsf page is below. Why the validate would be causing issues with the poll?

I am using primefaces 3.5 and JSF 2.1 running on Tomcat 7.

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:p="http://primefaces.org/ui">


<ui:composition template="/WEB-INF/templates/BasicTemplate.xhtml">

    <ui:define name="menuId">
    #{trackTabBean.setCurrentTab(trackTabBean.devicesTab)}
    </ui:define>
    <ui:define name="content">
    <f:metadata>
                <f:viewParam name="cgId" value="#{deviceBean.inputControlGroupId}"
                    validatorMessage="Control Group Id must be between 1 and 254">
                    <f:validateLongRange maximum="254" minimum="0" />
                </f:viewParam>
                <f:viewParam name="devId" value="#{deviceBean.inputDeviceId}" />
                <f:event listener="#{deviceBean.loadDevice}" type="preRenderView"></f:event>
    </f:metadata>
        <h:form id="deviceForm">            
            test (Load more code here but removed for testing)      
            <p:poll interval="5" listener="#{deviceBean.updateDetails}" update="deviceForm"/>   
        </h:form>
        <h:form>

        </h:form>
    </ui:define>

</ui:composition>
</html>

Your listener is not being called, as you probably have some validation errors. In the JSF Life-cycle Phase 3 is the "Process Validations" Phase, if this phase fails JSF will immediately jump to phase 6, which is "Render Response" Phase. So phase 5 "Invoke application" where the listener gets called, will be skipped.

Make sure that neither deviceBean nor inputControlGroupId is null and applies the given constraint.

#{deviceBean.inputControlGroupId}
