I would second Quartz' request. I'm familiar with cascade from the SQL DDL side, but 
it was a little unclear figuring it out for
Hibernate - the perspective seemed reversed.

Subject: [Hibernate] Simple Suggestions


  Hi folks! I love the simplicity of your framework. Unfortunatly, it took me a long 
time to figure out what exactly was the
consequence of each "cascade" declaration on the different types of relations. For 
instance, I didnt know whether cascade="all" in a
many-to-many rel would delete the content of the relation table only, or include the 
other table as well.

  My suggestion would be to make a small table with the cascades options, the types of 
relationships, and put sample java/SQL codes
and what would be deleted/updated/created, both in the DB and in the Java code (not 
always things get updated automatically!).

  I can do some of it myself, but I would have to make a test case for each situation, 
as I don't know the behaviour in most cases.

  Thanks for the excelent job!
