Thanks Volker, I figured that out, but still i cannot understand the usage of <from-action>. I needed the above information because i needed to call an action method and then transfer the control the navigation handler programmatically. I was able to achieve the same by first creating a MethodBinding, invoking it, getting the return value as an outcome and passing the same to the handleNavigation method of the NavigationHandler. It worked for me. ~madhav On 3/3/07, Volker Weber <[EMAIL PROTECTED]> wrote: > > 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: > http://svn.apache.org/viewvc/myfaces/core/trunk/impl/src/main/java/org/apache/myfaces/application/ActionListenerImpl.java?view=markup > > > Regards, > Volker > > > > > > 2007/3/2, Madhav Bhargava < [EMAIL PROTECTED] >: > > > > 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 > > **************** CAUTION - Disclaimer ***************** > > This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended > > solely for the use of the addressee(s).
