Cascading in component mapping support will have the following values: none (default): no cascading will be done. save: When saving an object, all of its component mappings will be saved as well (only if they are root). create: When creating an object, all of its component mappings will be created as well (only if they are root). delete: When deleting an object, all of its component mappings will be deleted as well (only if they are root). all: save+delete+create It is important not to confuse the fact that with component mappings they will be cascaded into the top most Resource. This feature related to component mappings that are also root searchable (i.e. objects that stand on their own, like Customer and Order), and any change to one, will result in cascading the change to the others.
