[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-6927) Cannot register a type through configuration if the type is parametrized

Cannot register a type through configuration if the type is parametrized ------------------------------------------------------------------------ Key: HHH-6927 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6927 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.5 Reporter: Stephane Nicoll Since I don't want to hardcode @TypeDefs in each class hierarchy that uses a custom type, I am using the {{cfg.registerTypeOverride}} method. This works fine for simple user type but I have a parameterized user type. In that case, using this method leads to a single user type instance being used and shared for all my entities and no parameter is injected at all. Looking a bit deeper I think I found the culprit in TypeResolver. {code:java} public Type heuristicType(String typeName, Properties parameters) throws MappingException { Type type = basic( typeName ); if ( type != null ) { return type; } try { Class typeClass = ReflectHelper.classForName( typeName ); if ( typeClass != null ) { return typeFactory.byClass( typeClass, parameters ); } } catch ( ClassNotFoundException ignore ) { } return null; } {code} base(typeName) will actually return the type that I have registered. Notice that basic does not take the {{parameters}} argument into account. Since it's not null it just returns that type. Maybe I did something wrong. I was surprised that cfg actually registers *instances* and not classes. Both @TypeDefs and hbm.xml specifies classes. Maybe adding an option to register a class programmatically?
