Thanks for answer. But I think there is other logic.
In ojb.properties I have SqlInLimit set to 200, but when prefetching of proxy collection is performed I found that field _limit in class PBCollectionProxyListener (inner of class QueryReferenceBroker) field m_ProxyPrefetchingLimit in CollectionDescriptor is =50 and method CollectionDescriptor.getProxyPrefetchingLimit() returns, of course, 50 - the default value for proxy-prefetching-limit. I tried to change attribute "proxy-prefetching-limit" in descriptor-repository and in collection-descriptor - no results.
More. If I have in owners collection more objects than proxy-prefetching-limit, I get a ClassCastException in class in PBCollectionProxyListener in method :
protected void addThisListenerTo(Object listenedObject)
{
_listenedCollection = (CollectionProxy) listenedObject;
_listenedCollection.addListener(this);
}
because reference to this method is
addThisListenerTo(owners.get(0));
This reference is in abstract class PBPrefetchingListener. PBCollectionProxyListener extends PBPrefetchingListener.
So I would like to change proxy-prefetching-limit or to find some solution not to get ClassCastException.
Of course, I can change constant 50 in source code of ObjectReferenceDescriptor, but I think this is not the best solution.
Thanks for any answer. Best regards Tadeus Garsva
P.S. I am sorry for my english.

hi tadeus,
this limit is defined in ojb.properties. the parameter is called SqlInLimit.

Hi,
I don't find any reference to method setProxyPrefetchungLimit in ObjectReferenceDescriptor class. Does it mean that proxy-prefetching-attribute in reference and collection descriptor can be changed only by calling this method and not by attribute in repository.xml?
Thanks in advance for answer. Best regards Tadeus Garsva
