Hi Andrus,
after some debugging, it turned out today that in some cases the number of
fetched objects exceeded the DataRowStore size... DOH!
I was fooled by the fact that the relationships are initially populated with a
ToOneFault that normally gets resolved from the local cache.
Please close this one.

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)
