Hot reloading of a custom jsf validate method from a backing bean doesn't work

Add a jsf validate method in a seam bean. A method having the following signature :

  public void validate(FacesContext context, UIComponent component,
            Object value) throws ValidatorException 

Use this method to validate a field when submitting the form. For example, on a field of type String, this can be configured directly using the "validator" property of the widget type "text".

 <properties widgetMode="edit">
   <property name="validator">#{testBean.validate}</property>

When the seam bean is hot -reloaded the method is never called.
