Description

During our testing we found out that the RefreshQuery does not work. The problem can be shown in the following code:

SelectQuery sq = new SelectQuery(Artist.class, someExpression);
sq.setCachePolicy(QueryMetadata.LOCAL_CACHE);
sq.setPageSize(pageSize);

// sq.setCacheGroups(new String[]

{ someKey }

); //optional, does not change the result

List<Artist> list1 = aContext.performQuery(sq);

Artist newArtist = otherContext.newRecord(Artist.class);
otherContext.commitChanges();

otherContext.performGenericQuery(new RefreshQuery(newArtist));
// otherContext.performGenericQuery(new RefreshQuery(new String[]

{someKey}

)); //does not make any difference

List<Artist> list2 = aContext.performQuery(sq);

//the following line prints 'false'
logger.info("cache refreshed = "+(list1.size() != list2.size()));

I tried hard to write a test case in cayenne, but I had some problems first with compiling the tests, then with actual test class/method itself.
