You need to define the listener as a top-level component setting the component
type
to the fully qualified path to the action listener.
<component jsfid="t:updateActionListener"
componentType="org.apache.myfaces.custom.updateactionlistener.UpdateActionListener"
..
...
</component...
However, this won't work without further customizations because this action
listener
is statefull and has special value binding attributes. The JSP tag has to do
some
special processing [1].
You will need to create a custom handler to create the listener. There is an
example in the sandbox for the Trinidad version of the same thing.
First you will need to add a commons chains config file to the WEB-INF folder
of your web app [2]. Add a catalog with the name "clayCustomizations".
Add a chain with the name of "preprocessAddActionListener" the the catalog.
<catalog name="clayCustomization">
<chain name="preprocessAddActionListener">
<command className="acme.tomahawk.CreateActionListenerCommand" />
</chain>
</catalog>
Next, create a commons chains command extending
"org.apache.shale.clay.component.chain.CreateActionListenerCommand".
Add the extra logic to handle the special attributes [3].
