How to identify which UIComponent fired an event?

Question

Dear kind sirs...
I am writing a JSF application using JDeveloper 10.1.3.4, I am using only JSF Core & JSF HTML...
What I am doing is defining say 2 or 3 buttons at runtime (HtmlCommandButtons), all having the same handler. It is working perfectly fine. However, I can't identify which one is firing the event.
the code that generates the two buttons is as follows:
HtmlCommandButton CB=(HtmlCommandButton) FacesContext.getCurrentInstance().getApplication().createComponent(HtmlCommandButton.COMPONENT_TYPE);
CB.setValue("T1");
CB.setId("T1");
*MethodBinding mbButton = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{backing_Admin_designpage.doit}",null);*
*CB.setAction(mbButton);*
*U.getChildren().add(CB);*
*CB.setRendered(true);*
*HtmlCommandButton CB2=(HtmlCommandButton) FacesContext.getCurrentInstance().getApplication().createComponent(HtmlCommandButton.COMPONENT_TYPE);*
*CB2.setValue("T2");*
*CB2.setId("T2");*
*MethodBinding mbButton = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{backing_Admin_designpage.doit}",null);*
*CB2.setAction(mbButton);*
*U.getChildren().add(CB2);*
*CB2.setRendered(true);*
finally the method is:
*public String doit(){*
*System.out.println("Hello");*
*return null;*
of course I can bind a separate method for each button, but I don't want to, I want this one event handler to do it for me.
and idea?
thanks in advance.

Hi,
define an actionListener either instead or addition to the action. The ActionEvent passed into this method has a getSource method that points to the UI component instance invoking it
