All components are serializable (java.io.Serializable). Like cloning, all children and descendants are serialized. If you serialize a component and then de-serialize it back, the result will be the same as invoking Component.clone()
save the component when ever you want to redraw the same state of component call isInvalidated() of the component.
isInvalidated
boolean isInvalidated()
Returns if this component needs to be redrawn at the client.
Application developers rarely need to call this method.
Note:
It always returns true if it doesn't belong to any page (since redraw is required if it is attached to a page later).
It always returns true if the current execution is not an asynchronous update (so redrawn is always required).
If its parent is invalidated, this component will be redrawn too, but this method returns false if invalidate() was not called against this component.
