Hi, You cannot add a component twice. A component can have just one parent.
I think jQuery clone() should work, but I'm not totally sure. You can use WicketObjects#clone() method to clone any kind of Object. It uses Java Serialization to do it. Just make sure you clone it before adding the component to its parent, because the relation will be cloned too.
