            <p:dataList value="#{messagesManagedBean.userInboxMsgs}" var="msg" id="cars"

                    <h:panelGrid  columns="2" cellpadding="5">

                        <h:outputLabel for="year" value="Full name: " />  
                        <h:outputText id="year" value="#{messagesManagedBean.selectedMessage.userFullname}" />  

                        <h:outputLabel for="color" value="User Id: " />  
                        <h:outputText id="color" value="#{messagesManagedBean.selectedMessage.userId}" style="color:#{tableBean.selectedCar.color}"/>  
                    </h:panelGrid>  
                </p:outputPanel>  
            </p:dialog>  

        </h:form> 



    </h:body>
</html>

它会打开对话框但不显示值。（对话框没有更新） * 注意 *之前，当我使用ui：repeat而不是datalist时，f：param方法很好。
