Passing JSF action methods into ui:include

Parameters like Java plain, complex objects and beans can be transfered into an ui:include to be available in the included page. An example:

<ui:include src="/sections/edit.xhtml">
    <ui:param name="editBean" value="#{editTemplate}"/>
    <ui:param name="param1" value="value1"/>
    <ui:param name="param1" value="value1"/>
</ui:include>

The facelets edit.xhtml has then an access to these parameters. Well, but what is about action methods? They can be passed by array notation. We can include a facelets from many other facelets and specify the action by its name. E.g.

<ui:include src="/sections/edit.xhtml">
    <ui:param name="editBean" value="#{editTemplate}"/>
    <ui:param name="deleteAction" value="deleteById"/>
    <ui:param name="obj" value="#{listTemplates.selectedId}"/>
</ui:include>

<ui:include src="/sections/edit.xhtml">
    <ui:param name="editBean" value="#{editTemplate}"/>
    <ui:param name="deleteAction" value="deleteByTemplate"/>
    <ui:param name="obj" value="#{listTemplates.selectedTemplate}"/>
</ui:include>

deleteAction is an action name as String which is defined in the passed bean #{editTemplate}. In the included edit.xhtml we can access the proper action and call it with parameter as follows

 
<h:commandButton value="Delete" action="#{editBean['deleteAction'](obj)}"/> 
 

or if you don't use EL 2.x

 
<h:commandButton value="Delete" action="#{editBean['deleteAction']}">
    <f:setPropertyActionListener target="#{editBean.selectedObject}" value="#{obj}"/>
</h:commandButton> 
 

Like JavaScript objects we can use the array notation in EL expressions.
