JSF: h:outputText; how to show a dash when the value is empty string?

Question

I\'m using h:outputText tags to display readonly data. Ex:

Answer 1

<h:outputText value="#{userHandler.user.phoneNumber != null 
    ? userHandler.user.phoneNumber : '-'}" />

Or, you could make a new outputText:

<h:outputText rendered="#{userHandler.user.phoneNumber == null}" value="-" />
