Re: How to use addActionListener

[Tushar]

From Jsp I understand that I can give mutiple actionlistner in one actionListener attribute. I want to simulate the same thing in java code using HtmlCommandLink class.

 

My code fragment is as below

 

    public HtmlCommandLink makeCommandLink(UIComponent comp, String actionEL, String listenerEL) {
        HtmlCommandLink uiLink = new HtmlCommandLink();
        if(actionEL!=null){
         uiLink.setAction(makeActionBinding(actionEL));
        }
        if(listenerEL!=null && !listenerEL.equalsIgnoreCase("")){
         Class[] arg = {ActionEvent.class};
         uiLink.setActionListener((makeListenerBinding(listenerEL, arg)));
        }
        uiLink.getChildren().add(comp);
        return uiLink;
    }

 

    public MethodBinding makeListenerBinding(String el,Class[] arg) {
     FacesContext ctx = getFacesContext();
     if (ctx != null) {
   Application app = ctx.getApplication();
   return app.createMethodBinding(el, arg);
   
     } else {
      return null;
     }
    }

 

Not I want to add two actionListeners in one HtmlCommandLink.I mean instead of using

uiLink.setActionListener((makeListenerBinding(listenerEL, arg)));

I want to use uiLink.addActionListner();

 

First one takes MethodBinding as a parameter but where as the other one takes ActionListner as a parameter.

You can only have one actionListener attribute though (I'm fairly
positive). The actionListener type only takes a Java class name, not a
method binding. If you need more than one action listener method
binding, you will have to make a custom UICommand object I believe.
