How to process with aggregate descriptors

[Steve Petruzza]

Hi,
I'm trying to use an example aggregate descriptor 
(RoomNumberAndDateTime) using this simple code:

       XMLInputSource input = new 
XMLInputSource("desc/analysis_engine/RoomNumberAndDateTime.xml");
       AnalysisEngineDescription desc = 
UIMAFramework.getXMLParser().parseAnalysisEngineDescription(input);
            
       AnalysisEngine seAnnotator = 
UIMAFramework.produceAnalysisEngine(desc);
             
       JCas cas = seAnnotator.newJCas();
       cas.setDocumentText("August 26, 2003 \n UIMA 101 - The New UIMA 
Introduction \n (Hands-on Tutorial) \n 9:00AM-5:00PM in HAW GN-K35\n 
August 28, 2003");

       seAnnotator.process(cas);
                      
       FSIndex indexAnnotations = cas.getAnnotationIndex();
       Iterator<Annotation> annoIt = indexAnnotations.iterator();

if I iterate on annoIt I find only annotations for RoomNumber but not 
for Date or Time (as the DocumentAnalyzer do), what I'm doing wrong?

Thanks

Steve
