How to set the id on detached Hibernate proxy without LazyInitializationException? -

i'm using object, has on 15 related entities (parents). in ui side need ids of these entities, don't need hibernate's fetch functionality , use lazy proxy concept avoid hit database on 1 hand , have objects populated ids on other.

to achieve have use property acces instead of field access parent entities:

@id @access(accesstype.property) // helps avoid database hit on get, not on set!!!     private long id; 

so far good, load object database (no joins made) , show on web ui relations (simple select inputs @ most). don't create clones (value objects) ui, use detached hibernate objects directly. when changes ui (change parent object) framework calls setid() related proxy entities , .... results in initialization of these proxies! here code hibernate basiclazyinitializer this:

else if ( method.equals(setidentifiermethod) ) {         initialize(); // here db hit occurs!!         setidentifier( (serializable) args[0] );         return invoke_implementation;      } 

and lazyinitializationexception occurs (sure, have no session @ point of time!).

so, there approach without creation of value objects entities, fetched database? can say, used data objects in ui directly, fetched (not proxies) , haven't had such problems these proxies...

i don't understand, why hibernate makes proxy initialization on setting (though doesn't on getting) @id field...

thanks in advance!
