The Woodstock components are based on JSF 1.2 and support the
javax.el.MethodExpression APIs. As of Woodstock 4.0, tag attributes such
as "action", "actionListener", and "validator" have been replaced with
"actionExpression", "actionListenerExpression", "validatorExpression",
etc. If I'm not mistaken, Facelets relies on the deprecated
javax.faces.el.MethodBinding APIs of JSF 1.1. Therefore, the components
can only be used in Facelets, if you use the older APIs. That is, the
deprecated setAction, setActionListener, and setValidator methods
inherited from JSF.
That said, instead of using the validatorExpression property, try
setting the validator property.
