Event Listener Tags

     <h:selectOneMenu value="#{form.country}" onchange="submit()"
        valueChangeListener="#{form.countryChanged}">
        <f:selectItems value="#{form.countryNames}"/>
     </h:selectOneMenu>

The same can be accomplished through listener tags:

     <h:selectOneMenu value="#{form.country}" onchange="submit()">
        <f:valueChangeListener type="com.corejsf.CountryListener"/>
        <f:selectItems value="#{form.countryNames}"/>
     </h:selectOneMenu>

Note difference:

• Attribute requires method binding (form.countryChanged)

• Tag requires a Java class (com.corejsf.CountryListener)
