> Class with @IdClass gets lazy-loaded when "id" field accessed
> -------------------------------------------------------------
>
> Key: HHH-3063
> URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3063
> Project: Hibernate3
> Issue Type: Bug
> Components: core
> Affects Versions: 3.2.2
> Environment: Windows, Postgres
> Reporter: Carl Allain
> Priority: Minor
> Attachments: BugIdClassIds.java, CountrySubdivisionPdoWithEmbeddedId.java, CountrySubdivisionPdoWithIdClass.java

> When I access the getter named getCountryIsoCode() of the following class (owning a CGLIB proxy that HB gave me), there is some lazy-loading activity that occurs. Of course, the field countryIsoCode is not tagged with @Id, but this is because of the @IdClass annotation, but I would expect the same "will-no-lazy-load-when-only-id-fields-are-accessed" regular behavior.
