Hibernate version:
Hibernate 3.0.5


Consider the following 2 classes:

Class A - lazy=true by default
Class B - lazy=true by default

Class B has a many-to-one association with classA (lazy=true on the association as well).

Now in a new session, if I read in class A using
session.get(), the fully initialized object is loaded (as expected).
I could access its properties even after calling session.close().


Now in a another new session:
If I read in classB using session.get(), all classB properties are initialized
and the related classA is lazily loaded (as expected).

Then, in the same session, I also read in the associted classA object by directly calling session.get(). At this point I expect the object to be fully initialized.

Now I close the session. When i try to read the id property from the now detached classA object, i get null (just null, no lazy initialization exception).

Before closing the session, I even tried initializing the classA object by calling Hibernate.initialize(). Id property is still null after the session is closed().

As I explained at the begining, this doesnt happen when I load the object directly in a new session. It only happens when the object is first read in as an associated class to classB. (i use session.get in all cases)

Note: when I make the lazy= false in the m-to-o association, the subsequent session.get(), initializes the object fully. But I dont want to change the mapping, I just want the associated object to fully initialized when i read it thro' session.get().

What am I missing?

The problem is actually worse than I initially thought:

the Id property is null even when the session is open. Whats more strange is, I could see all other proerties except for the id property.

My guess is this has some thing to do with the CGLIB enhancer class of my class.

Any pointers?

Never mind. I figured out the problem. It had to do with the final methods (my get and set ID methods were).
