Boa tarde,
Há algo errado ao usar o primefaces 4.0 na seguinte página?

			<p:dataTable id="lazyDataTable" value="#{playerMB.allPlayers}"

				<p:ajax event="rowSelect" update=":playerDialogForm"
					oncomplete="playerDetails.show()" />

				<p:column>
					<f:facet name="header">Name</f:facet>
					<h:outputText value="#{player.name}" />
				</p:column>
				<p:column>
					<f:facet name="header">Age</f:facet>
					<h:outputText value="#{player.age}" />
				</p:column>
			</p:dataTable>
		</h:form>

		<p:dialog widgetVar="playerDetails" header="Player" modal="true">
			<h:form id="playerDialogForm">
				<h:panelGrid columns="2">
					<h:outputText value="Id: " />
					<h:outputText value="#{playerMB.player.id}" />
					<h:outputText value="Name: " />
					<h:outputText value="#{playerMB.player.name}" />
					<h:outputText value="Age: " />
					<h:outputText value="#{playerMB.player.age}" />
				</h:panelGrid>
			</h:form>
		</p:dialog>
	</f:view>
</h:body>
</html>

Quando uso o 3.2 ela mostra as valores no banco, mas usando 4.0 mostra que não existem registros.
