generic component binding

[hicham abassi <ha...@gmail.com>]

Hello,

Is it possible to bind any jsf component to a generic jsf tag.

<h:baseJSFTag binding="#{managedBean.anyJsfComponent}"/>

I want to know if we can generate dynamically bind all jsf components
on a jsp page without specifiing the jsf tag type.

Thanks

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>

Regards,

Simon

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

If you use an Action, no.

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)

Specifically, you'll probably want to bind to a UIComponent variable.

			    binding="#{page.locationComponent}"

    private transient UIComponent locationComponent;
    public UIComponent getLocationComponent()
    {
        return this.locationComponent;
    }
    public void setLocationComponent(UIComponent locationComponent)
    {
        this.locationComponent = locationComponent;
    }

I do this all the time to associate FacesMessages to a specific component.
            facesContext.addMessage(locationComponent.getClientId(facesContext),
                    new FacesMessage(FacesMessage.SEVERITY_ERROR,
                    	"message summary", "message detail")
                );

You have to bind to a method.  You can do something like :

<h:inputText value="#{fooBean.someMethod} binding="#{barBean.someOtherMethod}"/>

or use the same bean for both the binding and value attributes like:

<h:inputText value="#{fooBean.someMethod} binding="#{fooBean.setTextComp}"/>
