> public InvalidValue[] validate(FacesContext context, String propertyExpression, Object value)
> The propertyExpression, which is extracted from a ValueBinding, by ModelValidator, may be null in some circumstances.  I use custom ValueExpression implementations in a couple of places which are not derived from an EL string so return null from getExpressionString().
> validate() should probably check for null and quietly 'return new InvalidValue[ 0 ]' like it does when it cannot parse the expression string properly.
