Hi Björn,
I assume this call cause the NPE
> org.apache.ojb.broker.core.QueryReferenceBroker.getFKQuery1toN(QueryReferenceBroker.java:604)
The source looks like
private QueryByCriteria getFKQuery1toN(Object obj, ClassDescriptor cld, CollectionDescriptor cod)
{
ValueContainer[] container = pb.serviceBrokerHelper().getKeyValues(cld, obj);
ClassDescriptor refCld = pb.getClassDescriptor(cod.getItemClass());
// line 604
I think the CollectionDescriptor returns 'null' as item class.
So I think something in your mapping or manipulation of metadata (made by you?) is wrong.
regards, Armin
