Is anybody aware of anything in RC2 that would prevent getCollectionByQuery() from
realizing sub-objects? I get N records using getCollectionByQuery() successfully,
but this OfferVO subobject continues to not show its ugly head unless I manually get
each sub-object.
I have auto-retrieve="true" everywhere.
I successfully get a different sub-reference on a different non-collection object.
My mapping is correct in that manual retieval works.
I thought sub-objects would be realized with getCollectionByQuery() unlike with
getIteratorByQuery().
I am wondering if it could have something to do with the fact that the Collection of
OrderItemVO has 3 primary keys or something to do with the below setting in the
OJB.properties I needed to allow for '->' Single Table Aggregation. '->' was only
allowed as far as I know in RC2 using this setting. I don't know if it was
implemented in the default setting since.
PersistentFieldClass=org.apache.ojb.broker.metadata.fieldaccess.PersistentNestedFieldMaxPerformanceImpl
My repository.xml as it is today for the two important tables follows:
