package javax.faces.component;

ActionSource2 extends ActionSource and provides a JavaBeans property analogous to the "action" property on ActionSource. The difference is the type of this property is a javax.el.MethodExpression rather than a MethodBinding. This allows the ActionSource concept to leverage the new Unified EL API.

Since:
1.2
public interface ActionSource2 extends ActionSource {
    // -------------------------------------------------------------- Properties

    

Return the javax.el.MethodExpression pointing at the application action to be invoked, if this UIComponent is activated by the user, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property.

Note that it's possible that the returned MethodExpression is just a wrapper around a MethodBinding instance whith was set by a call to ActionSource.setAction(javax.faces.el.MethodBinding). This makes it possible for the default javax.faces.event.ActionListener to continue to work properly with older components.

    public MethodExpression getActionExpression();

    

Set the javax.el.MethodExpression pointing at the appication action to be invoked, if this UIComponent is activated by the user, during the Apply Request Values or Invoke Application phase of the request processing lifecycle, depending on the value of the immediate property.

Any method referenced by such an expression must be public, with a return type of String, and accept no parameters.

Parameters:
action The new method expression
    public void setActionExpression(MethodExpression action);
