Subject svn commit: r414756 - in /incubator/cayenne/main/trunk/cayenne/cayenne-java/src/cayenne/java/org/objectstyle/cayenne: CayenneContextQueryAction.java remote/RemoteIncrementalFaultList.java
Date Fri, 16 Jun 2006 06:48:27 GMT
Author: aadamchik

New Revision: 414756

URL: http://svn.apache.org/viewvc?rev=414756&view=rev
Log:
Local caching of client paginated lists is broken 
 
 * on the remote client, paginated query is intercepted before the local cache, thus local
cache settings are ignored.
 * on the server: RemoteIncrementalFaultList overrides the query cache key, so cached IncrementalFaultLists
can't be reused and a new list created on every query, taking lots of memory.

(I can't log in to Jira due to Apache network problems; I will enter the bug once this is
resolved)
