Hi !

I will try to help:
If you need only one cascade type value you use the single item notation:
You can OR the casace type values:
The following sample will cascade any operation beside a delete (and here you will need the array notation):
cascade={CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH} 

Q2: I think you don't need to initialize the relationship field with a value. Set it to null, the container will do the rest.
When you create relationship items you should update both sides of the relationship.
Something like:
  | unsavedNewOwnedItem.setObject (myObject); 

Hope this helps
