Description
There is a problem with the behaviour of binding attribute from actionListeners, validators and converters.
I have this test. The objective is explore how binding attribute is doing things comparing jsf ri 1.2 and
myfaces 1.2.1-SNAPSHOT, trying to detect bugs on myfaces

When you call the page the first time, this is the output for <h:messages> tag :
JSF RI:
- This is the message for phase before RENDER_RESPONSE 6
- Component:javax.faces.component.html.HtmlInputText@164de59
- Validator:null
- Converter:null
- ActionListener:null
Myfaces:
- This is the message for phase before RENDER_RESPONSE(6)
- Component:javax.faces.component.html.HtmlInputText@18c5e67

- Converter:javax.faces.convert.BigDecimalConverter@1e3bbd7
- ActionListener:org.apache.myfaces.bindingCLV.DummyActionListener@4133b0
QUESTION 1: Why do I create an object that I do not use?. Myfaces is wrong, and JSF RI has the correct behaviour.
The first time that I load a page, it's unnecesary to create those objects.
And when you press the button or submit the form:
JSF RI:

QUESTION 2: Why I not have bindings assigned before INVOKE_APPLICATION ?(in this time is of value have a binding attribute) .
Again JSF RI has the correct behaviour and Myfaces is wrong. Myfaces create the validators, converters and
actionListeners on correct time, but not assign bindings when is supposed to do. If I assign a binding for
converter, validator or actionListener, I should be assigned minimum before INVOKE_APPLICATION, or better,
converters and validators on PROCESS_VALIDATIONS, and actionListeners in INVOKE_APPLICATION.
Looks a little bit difficult but I will try to find a solution for this issue.
