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
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.
