Hi

I have an object A that contains a list of object B and B contain a list of object C. I’m doing some lazy loading. I get my object A and all the lists of object B. I don't need to get C. When saving, all C related to B are erased. How can I save A & B without touching C ?

Thank you for any help.

If B existed, and had Cs, and you didn't do anything strange to that collection in your code (such as reassigning an empty collection or accidentally removing all), then there is no reason why the Cs should be lost!

If, on the contrary, your problem is that newly created Cs are not persisted, then revise your "cascade" settings on the collection of Cs, by adding the operation you use to persist B (set it to cascade="save", cascade="persist" cascade="all", etc).
