You might also be able to return null in controles.getTextComponent() and accomplish the same thing without having to make another bean or change scope.   My guess is that you only want a reference to the component, and you are not trying to create a new component.

public UIComponent getTextComponent() { return null; }

> There's a problem in the validation phase when you mix ajax action and a binding value in the same form. For example I have this simple form:
> <h:form id="form">
> 	<h:inputText id="text" value="#{controles.text}" validator="#{controles.validateText}" 
> 	binding="#{controles.textComponent}"/>		
> 	<br/><br/>
> 	<h:commandButton value="validate">
> 		<f:ajax event="click" render="text" listener="#{controles.clearText}" execute="@form" immediate="false"/>
> 	</h:commandButton>
> </h:form>
> And when validate button is clicked the validator method validateText is called twice the first time, 3 times for the second submit and one more time each time the ajax action is fired.
