Databinding on NotificationBar in XML View

Hi all,

i am fighting with databinding on a NotificationBar in an XML View since hours.

Could anybody tell me how to bind data correctly.

I am using the following XML View:

<core:View xmlns:core="sap.ui.core" xmlns:mvc="sap.ui.core.mvc"

xmlns="sap.m" xmlns:ux3="sap.ui.ux3" controllerName="ui5notificationbardemo.NotificationDemo"

xmlns:html="http://www.w3.org/1999/xhtml">

<Page title="Title">

  <content>

  <ux3:NotificationBar id="notificationBar"

  display="displayListener">

               <ux3:notifiers>

  <ux3:Notifier>

  <ux3:messages>

  <core:Message text="My text goes here" />

  </ux3:messages>

  </ux3:Notifier>

  </ux3:notifiers>

  </ux3:NotificationBar>

  </content>

</Page>

</core:View>

Thanks in advance,

Martin
