Patrick Lisser commented on HB-232:
-----------------------------------

Is there any news on that issue (wrapping natively generated id's with custom types)?

Or any known workarounds?

by the way, I'm using Hibernate 3.1

> All of my persistent objects have a custom primary key object.  
> For instance, my Part object has a PartID as the key.  This allows me to perform compile time type checking in my service layer.
> I was ably to create a UserType that converted the coulmn type of integer to PartID.  No problem, it worked great.  However, the IdentityGeneratorFactory throw an exception because my custom types return PartID.class as the return type.  The IdentityGeneratorFactory's 'get' method only takes classes that are of type Integer.class, Long.class, and Short.class.  The API should be changed so that the get method returns a Serializable instead of a Number, and takes a Type instead of a class.  This would allow the IdentityGeneratorFactory to return the custom class type.
