Just for clarity: While the information goes both ways, the form component remains in charge of the lifecycle. During rendering FormSupport is pushed in the Form component's beginRender and popped in it's cleanupRender, and in an action (form submit) FormSupport is pushed and popped from within the onAction event handler. The page or component containing the form has access to the FormSupport only when the form or one of its sub-components trigger an event between the time that the object was pushed and popped.
