Re: generic component binding

when I bind several components to that method, is there a way to find out
which component triggered the method?




    public UIComponent getLocationComponent()
    public void setLocationComponent(UIComponent locationComponent)

If what you want is to know *why* the method was called, rather than 
specifically to get a reference to the UIComponent that triggered it 
then you can attach a t:updateActionListener to the component. The 
updateActionListener will execute before the action attribute executes.

   <h:commandButton action="#{bean.execute}">
     <t:updateActionListener property="#{bean.mode}" value="search"/>
   </h:commandButton>

Simon

If you use an ActionListener, you should be able to find the original
component from the ActionEvent.

If you use an Action, no.
