'NHibernate.AssertionFailure: no collection snapshot for orphan delete' when saving an entity with an empty collection with delete-orphan cascade

Ok... so the issue can be closed here.
Here mean NH issues....
Like you can see this JIRA is for NH and NH.Contrib projects; go to home page and you can find NHMA project to submit the JIRA (remember to write a reference to "NH-1419")

Fabio Maulo,

You are right, when I used the xml based mappings that you submitted, everything works perfectly, so it appears that the issue is with the NHibernate.Mapping.Attributes assembly? I noticed that the NHibernate.Tests project didn't have a reference added to NHibernate.Mapping.Attributes assembly, and I assume this is because of the recent split between NHibernateContrib and NHibernate.Core. Is there an appropriate place for me to recreate the issue using the attribute based mappings?

Thanks for all of your help so far, I sincerely appreciate it.

If you want see the test without download NH sources take a look here

Hi Brandon.
I try a test in 2.0.0 branch and it appear like "Not an issue".
Note that I write the mapping xml based on the attributes you write using NHMA.
I'm going to commit the test.
Please check it and if you find something else we can reopen this issue.

Based upon your comment, I changed the cascade style to no longer use the 'all' cascade style to see if it was the 'refresh' cascade function that was causing the error. Even when I changed the cascade style to 'save-update,delete-orphan' I get the same error. If I use the 'all' cascade mode, and exclude 'delete-orphan' I don't get the error anymore.
