--------------------------------------
Hi Robert,
in general to-one prefetch works just fine, so there may be something specific
to your mapping of this relationship. Could you post a sample mapping that has
the affected tables/entities and relationships between them? (if you don't want
to make it publicly visible, you can email it to me directly: andrus at
objectstyle dot org)
> Prefetch on SelectQueries doesn't resolve ToOneFaults
> -----------------------------------------------------
>
> Key: CAY-1115
> URL: https://issues.apache.org/cayenne/browse/CAY-1115
> Project: Cayenne
> Issue Type: Bug
> Components: Cayenne Core Library
> Affects Versions: 1.2 [STABLE]
> Environment: 1.2.4 on Linux
> Reporter: Robert Wruck
> Assignee: Andrus Adamchik
>
> final SelectQuery q = new SelectQuery(MyObject.class);
> q.addPrefetch("myRelObject");
> final List l = dataContext.performQuery(q);
> For each element in the returned List, myRelObject is a ToOneFault that will
> be resolved by a separate query.
> This result is not affected by setSemantics on the prefetch (JOINT, DISJOINT
> behave just the same way).
> Expected result: myRelObject is filled with the prefetched entity object.
