Query does not return range key attribute value

[irakitin]

I have a table with the following attribute definitions {hash:"id", S; range: "timestamp", S}. When I query all elements withAttributeToGet("id", "timestamp"), I'm returned only items with "id" field, but not "timestamp".

Can you confirm that the exact same code works as intended with DynamoDB?
Can you past all the code related to your problem?

Table is created with the following code:

    try {
        dynamoDbService.getTableInfo(tableName);
    } catch (ResourceNotFoundException rnfe) {
        try {
            Future<TableDescription> table = dynamoDbService.createTable(tableName,
                    new AttributeDefinition().withAttributeName("id").withAttributeType(ScalarAttributeType.S),
                    new AttributeDefinition().withAttributeName("timestamp").withAttributeType(ScalarAttributeType.S),
                    rcu, wcu);
            table.get();
            return true;
        } catch (ExecutionException | InterruptedException e1) {
            throw Throwables.propagate(e1);
        }
    }

I query items with the following code:

                    Condition idCondition = new Condition()
                            .withComparisonOperator(ComparisonOperator.EQ)
                            .withAttributeValueList(new AttributeValue().withS(id));
                    Map<String, Condition> condition = new HashMap<>();
                    condition.put("id", idCondition);
                    QueryRequest queryRequest = new QueryRequest()
                            .withTableName(entityTable.getName())
                            .withAttributesToGet("id", "timestamp")
                            .withScanIndexForward(false)
                            .withKeyConditions(condition);
                    if (!lastQueryKey.isEmpty()) {
                        queryRequest = queryRequest.withExclusiveStartKey(lastQueryKey);
                    }
                    QueryResult queryResult = client.query(queryRequest);
                    lastQueryKey = queryResult.getLastEvaluatedKey();
                    List<Map<String, AttributeValue>> entityItems = queryResult.getItems();

After that entityItems contain items only with "id" field. I confirm this works in DynamoDB, I used to run it before, and when I switched to Alternator, I encountered the misbehavior.

Interesting, there should of been a test for this. Don't think I'll be
able to get to it soon. Best bet is to start on it yourself.
