Hi Madhav,
the action methodBinding is handled in the defaultActionListener, which is
invoked also in
broadcast() from UICommand.
NavigationHandler.handleNavigation() is done in processAction of
defaultActionListener:

Hi All,
HtmlCommandLink and HtmlCommandButton extend UICommand component class.
UICommand creates 2 MethodBindings – action and actionListener.
I was looking at the code for UICommand class and I could locate where the
registered actionListeners were getting executed – *broadcast* method but
I was not able to figure out where the action method was getting invoked and
how does NavigationHandler takes control from there on.
In NavigationHandler javadoc the following is mentioned:
public abstract void *handleNavigation*(javax.faces.context.FacesContext
context,
java.lang.String fromAction,
java.lang.String outcome)
*Parameters:*
context - The
FacesContext<http://java.sun.com/javaee/javaserverfaces/1.1/docs/api/javax/faces/context/FacesContext.html>for
the current request
fromAction - The action binding expression that was evaluated to retrieve
the specified outcome, or null if the outcome was acquired by some other
means
outcome - The logical outcome returned by a previous invoked application
action (which may be null)
Does it mean that if I create a MethodBinding out of an action EL
expression and then invoke the same, then will it execute the action method
and then automatically call the method specified above to navigate to next
view according to the navigation rules defined?
Any insight into this will be helpful.
Regards,
Madhav
