JavaEE Web API 8.0.1 · javax.faces.component.ActionSource2

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 MethodExpression rather than a MethodBinding. This allows the ActionSource concept to leverage the new Unified EL API.

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`. This makes it possible for the default `ActionListener` to continue to work properly with older components. Returns:MethodExpression the action expression.
