> Hibernate could not work properly when I use lazy load in many-to-one situation.you can run the test case in attachment.
> I try to get primary-key property of parent object which get from child object property.Hibernate query the parent object from database by foreign key successfully. But when I try to use org.hibernate.property.Getter Interface to read some property, hibernate return null to me. 
> My code in attachment can be described as follow:
> <1>Test function "TestEagerLoadManyToOne" using Eager load can pass the test. Code logic are:
> 1)Load Child object from database 
> 2)Get "parentObj" property and test whether "parent_id" field in parent is NULL;
> 2)Use org.hibernate.property.Getter to get "parent_id" field and test the result.
> <2>Test function "TestLazyLoadManyToOne" do exactly same thing just like "TestEagerLoadManyToOne", but the "Child" class change "parentObj" property to lazy load mode. this test function could not pass.
> Please fix this issue. It's crucial to my project.
