Hi
Does anyone know if prefetched relationships can reach more than one "layer"
of references/collections from an class being queried?
E.g. If I have a class A that I an querying and it has a 1:m relationship
with some class B, with the relationship defined by the name "allb",
and then each B has 1 1:1 relationsbip with another class C, with the
relationship called "singlec", is the following supposed to work:
Criteria criteria = new Criteria();
// configure the criteria
...
// add prefetched relationships
criteria.addPrefetchedRelationship("allb");
criteria.addPrefetchedRelationship("allb.singlec");
Query q = QueryFactory.newQuery( A.class, criteria);
I can get the single layer if indirection (e.g.
criteria.addPrefetchedRelationship("allb")) to work, but when I try the
above I get
an error message from OJB saying that it cant find the relationship
"allb.singlec". One thing to not is that I can specify query criteria
on this 2 level relationship i.e.
criteria.addEqualTo("allb.singlec.somefield", "test value");
where somefield is a field in the class C.
