Reference to a component stored on bind does not cleaned properly on unbind.
Instead, local paremeter is cleaned:

/** the component that this handler is bound to. */
private Component component;

@Override
public final void bind(final Component hostComponent)

{ ... component = hostComponent; ... }

@Override
public final void unbind(Component component)

{ onUnbind(); component = null; super.unbind(component); }

It prevents reusing AbstractAjaxBehavior.
