Primefaces poll not updating panel - jsf-2

Question

I can't figure out why my primefaces poll will not update any components.
<p:poll widgetVar="poll"
interval="#{messageBean.refreshInterval}"
listener="#{messageBean.refreshLiveData}"
update=":transactionLogForm:tabViewMain:liveViewPanel"/>
The refreshLiveData method gets called successfully but it refuses to update the outputText component (or any component for that matter).
<p:tab id="liveViewTab" title="Live View">
<h:panelGrid id="liveViewPanel" columns="6" cellpadding="5">
<h:outputText value="Live View Enabled: " />
<p:selectBooleanCheckbox value="#{messageBean.liveViewActive}">
</p:selectBooleanCheckbox>
<h:outputText value="Interval: " />
<p:spinner id="interval" value="#{transactionLogBean.refreshInterval}" />
<h:outputText value="Last Update:" />
<h:outputText id="lastUpdated" value="#{transactionLogBean.lastUpdated}" />
</h:panelGrid>
</p:tab>
Here is the full code from within the body tags:
<p:layout id="mainLayout" fullPage="true" style="height:100%" >
<h:form id="transactionLogForm">

I'm using JSF 2.0, Primefaces 3.4.RC1

Problem solved - it was a backing bean issue after all and had nothing to do with the poll itself which was working fine.
