I've been trying to work out some cascading issues with my application and have run into a problem. The problem is that I have a composite-id on my ThingAddress table that is comprised of two columns - both of which are foreign keys. I'd like to apply cascade="all" to one of the columns and cascade="none" to the other.
Now, when I do so and run my JUnit test, it tells me
Code:
2005-05-02 07:57:48,376 ERROR [main] util.XMLHelper$ErrorLogger (XMLHelper.java:48) - Error parsing XML: XML InputStream(11) Attribute "cascade" must be declared for element type "key-many-to-one".
I can only assume that this is a typo and that it really wants to say "cascade must not be declared" because in the DTD I don't see a reference to cascade for the composite-id entity.
I'd really appreciate:
a) To know if the error message is innacurate
b) To know how I can apply cascade attributes to the objects in this mapping. It's a legacy schema, so I can't do anything to the table. Can I map it in a different way? Can I reflect the same columns both in the composite-id as well as in another attribute? Can I apply some formula?
Thanks in advance!
