Facelets (Source) Tags
These are a key feature of facelets but there are no examples and the reference manual gives gives only the bare bones.
Example - Requirement
Resuable Yes/No Buttons which can have custom actions defined.
Use - examplePage.xhtml
Add xmlns:my="http://my.com/jsf/my" to your namespace definitions
Use the tag:
<my:yesNoButtons yesBean="The specified item was not found." yesAction="deleteUser" noBean="" noAction="deleteCity" />
Source - yesNoButtons.xhtml
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html">
<ui:composition>
<h:commandButton value="Yes" action="#{yesBean[yesAction]}"></h:commandButton> <h:commandButton value="No" action="#{noBean[noAction]}"></h:commandButton>
</ui:composition>

Of course, you could also apply a default style to your buttons, allow i8ln messages to be used as button labels, theme the buttons, allow view-id's to be passed for navigation...
