    Local cache doesn't work with paginated queries and DataContext
    ---------------------------------------------------------------

             Key: CAY-644
             URL: http://issues.apache.org/cayenne/browse/CAY-644
         Project: Cayenne
            Type: Improvement

      Components: Cayenne Core Library
        Versions: 1.2 [STABLE], 3.0, 2.0 [STABLE]
        Reporter: Andrus Adamchik
         Fix For: 3.0

    Per CAY-570, paginated queries and caching should work on remote clients (although see CAY-643), however doing it in the DataContext results in cache settings being ignored (for the same reason as CAY-570) -

    From DataContextTst - the last assertion fails:

        public void testPerformPaginatedQueryLocalCache() throws Exception {
            SelectQuery query = new SelectQuery("Artist");
            query.setPageSize(5);
            query.setCachePolicy(QueryMetadata.LOCAL_CACHE);
            
            List objects = context.performQuery(query);
            assertNotNull(objects);
            assertTrue(objects instanceof IncrementalFaultList);

            assertTrue(((IncrementalFaultList) objects).elements.get(0) instanceof Artist);
            assertTrue(((IncrementalFaultList) objects).elements.get(7) instanceof Map);
            assertTrue(objects.get(7) instanceof Artist);
            
            // do it from cache
            List objects1 = context.performQuery(query);
            assertNotNull(objects1);
            assertSame(objects, objects1);
        }
