This is a follow-up to this post, especially nordborg's explanation about one-to-one

Problem is as follows:

Start a->b , a->c , c->d are all mapped one-to-one



Result on refreshing a:
select ... from a_table
select ... from b_table, c_table, d_table

Then i changed it to a->b and c->d both constrained and lazy:



Result on refreshing a:
select ... from a_table
select ... from c_table

But what didn't fit in was when i changed it to a->c being constrained and lazy



Result on refreshing a:
select ... from a_table
select ... from c_table

So data from c_table is always loaded, any thoughts why this happens and how to prevent it?
I know it's doable with many-to-one but i just want to know whis this happens with one-to-one.

Thanks in advance

That really seems to be weird, as "cees" and "dees" are mapped exactly the same way, but your property-ref. But maybe thats the problem:
Property-ref is the part, which I don't understand in your mapping. Do you really have a property "private ClassA c_id" in ClassD?? Because this is what your mapping states. Notice that property-ref is used, when you join a bidirectional one-to-one association on a foreign key instead of using the same primary key.

Sorry I didn't write that clear enough
ClassA
- ClassB
- ClassC

ClassC
- ClassD

ClassD is mapped in ClassC the same way as ClassC is mapped in ClassA (with property_ref)

ClassC has an "a_id"
ClassD has and "c_id"

ClassA and ClassB share the same primary key
