+ * Revision 1.2 2003/08/19 01:53:12 chochos
+ * EOObjectStore had some incompatible return types (Object instead of EOEnterpriseObject, in fault methods mostly). It's internally consistent but I hope it doesn't break anything based on this, even though fault methods mostly throw exceptions for now.
