Name and version of the database you are using:Oracle 9.0.2
The generated SQL (show_sql=true):Doesn't get that far.
Debug level Hibernate log excerpt:Included above exception.
Basically, the Person has and XREF table (Relations) that return different type of Locations (Home address, work address, etc.); however, my applications bombs when the Person has the same Location for more than one Relationship (related to the same entity twice).
As mentioned above, the code is used inside of Spring's OpenSessionInViewFilter and is along the lines of:
Code:
Person person = session.get(Person.class....);
Castor.marshal(person);
So of course castor calls all of my getters and if it is a collection of some sort, it calls .iterate() to retrieve the values from an Abstract[Set|Collection]Persister. For some reason, the session becomes null in this class at some point but like I said, only when the same object is related twice.
I've tried lazy="true" and lazy="false". Different exceptions but same sort of error occur.
Any help is appreciated. I've got a deadline this week and I had to fight pretty hard to use Hibernate on this project. I'm hoping to resolve this so I don't get the "I told you so" look from upper management ;). Thanks in advance.
