Hi @all

I have a special requirment for fetching collections lazy at runtime. Situation: A Class: CodeTypes has zero or n Classes: CodeValues.

As default in the mapping file, of CodeType, the lazy attribute is "false" on the set (see below).

Now i have a special case: how i can load a CodeType at Runtime without loading all his CodeValues. Is this possible ?

I have tried the following code:

session.createCriteria(CodeType.class)
.setFetchMode("CodeType.dcaCodevalues", FetchMode.LAZY)
.add( Restrictions.eq("id", type.getId()) )
.uniqueResult();

but this codes works not, all CodeValues are loaded also.

Thanks for all inputs !
