Composite Keys Query

[Renato Marroquín Mogrovejo <re...@gmail.com>]

Hi all,

I am using some composite keys to get just some specific composite
columns names which I am using as follows:

create column family video_event
  with comparator = 'CompositeType(UTF8Type,UTF8Type)'
  and key_validation_class = 'UTF8Type'
  and default_validation_class = 'UTF8Type';
  column_metadata =
  [
    {column_name: event, validation_class: UTF8Type}
  ];

The data it contains is as follows:

RowKey: otaner9902:94dd885a-655f-4d5c-adaf-db6a6c51d4ac
=> (column=start:2013-01-17 13:31:05.072, value=, timestamp=1358447465294000)
=> (column=stop:2013-01-17 13:31:05.402, value=2013-01-17
13:31:05.402, timestamp=1358447465402000)

And I am using the following code to retrieve the data:

Composite start = compositeFrom(startArg, Composite.ComponentEquality.EQUAL);
        Composite end = compositeFrom(startArg,
Composite.ComponentEquality.GREATER_THAN_EQUAL);

 VideoEventCompositeQueryIterator iter =
                new VideoEventCompositeQueryIterator("ALL", start,
end, keyspace);

The thing is that I keep on getting zero columns back and I am really
getting to a point that its driving crazy. I have uploaded all my code
to my github account[1] and this specific class is in[2].
Any pointers are more than welcome! Thanks in advance!
