UserType and Basic(fetch=LAZY)

Hi all,

I've got a relatively simple mapping with the exception of one UserType. The UserType is for a Clob column, which stores XML. I've mapped the property like this:

Code:

  @Type(type = "com.toyota.papis.access.hibernate.JAXBMessageType",
    parameters = @Parameter(name = "type", value = ".....VehicleSpecificationMsg"))
  @Basic(fetch = FetchType.LAZY)
  private VehicleSpecificationMsg message;

However the property is always loaded (regardless of whether it is accessed or not). Does Hibernate support lazy loading of custom types or have I missed something else?

cheers

you have to enhance your classes to makeproperty lazy loading work

I read in the documentation that you can enable bytecode instrumentation to get this to work, but that the recommended alternative is to use the projection capability of EJB-QL or Criteria queries. I looked around and couldn't find too much to read on that, I think becuase I don't know how to begin looking into that. Does anyone have some sites I can look at, or basic strategies to get me on the right path?
