Hello.
I have a toOne relationship A->B. Both A and B use the same multi-
column primary key. All Bs are already in the DataRowStore.
DataObjectUtils.objectForPK() on any of the Bs work fine with no
queries to the database.
If I create a new DataContext and fetch in some As and issue a.getB(),
then a query is run on the database. Why not look in the DataRowStore
first?
I have debugged this and found some interesting stuff in
DataDomainQueryAction to handle RelationshipQuery around line 188.
// check if we can derive target PK from FK... this
implies that the
// relationship is to-one
if (relationship.isSourceIndependentFromTargetChange()) {
return !DONE;
}
The thing that makes this return is
ObjRelationship.isToDependentEntity() that returnes true. Why does
this have to force us to requery the toOne relationship? Any way
around this?
This is happening on trunk, M4 and M3
Regards,
- Tore.
