ActionSupport is not serializable

If one wants to send some action that extends ActionSupport through serialization, it's not possible because in ActionSupport there are some variables that aren't either transient or serializable (variables are of type TextProvider & ValidationAware).
Probably ValidationAware should extend java.io.Serializable, and TextProvider I'm not sure if it makes sense to send over through network, and if shouldn't be transient.
