[HibernateException: You may not dereference an collection with cascade="all-delete-orphan"]


Thanks,
-M

It looks like you are doing:

where MyCollection was initialized by NHibernate...
(In this case, the session will no longer be able to tell which items are orphan...)

You response is a bit cryptic. Can you elaborate a little bit more.

Thanks

The word "dereference" here means you can't replace the whole collection belonging to an object by another new instance, i.e. doing something like:

myEntity.MyCollection = new ArrayList/HashMap/Whatever();

Since then it's not possible to reliably track changes in the collection. Check your code for this and do a Clear() instead.
