Hi all,
I'm trying to make a simple function which take an annotation and a Type 
and print all the value associated with all the feature present in the Type.
This is the recursive function:

public void printTypeSystem(Type uimaType, Annotation annotation, int 
level){
         String levelString="\t";
         for (int i=0; i<level; ++i)
             levelString += "\t";
         List <Feature> feauturesList = uimaType.getFeatures();
         if(level == 1)
             System.out.println("T.S. = "+uimaType.getName());
         for(int i=0; i<feauturesList.size(); ++i){
             Feature feature = (Feature) feauturesList.get(i);
             String nameFeat = feature.getName();
             if(!nameFeat.startsWith("uima.")){
                 Type typeRange = feature.getRange();
                 if(typeRange.isPrimitive()){
                     String value = 
annotation.getFeatureValueAsString(feature);
                     System.out.println(levelString+"F: "+nameFeat+" = 
"+" V: "+value);
                 }
                 else{
                     System.out.println(levelString+"F: "+nameFeat+" = 
"+" TS: "+typeRange.getName());
                     printTypeSystem(typeRange, annotation, level+1);
                 }
             }
         }
     }


The problem is that I'm able to print only the values associated with 
the "first level" of features (when they are primitive). If for example 
a Type has a feature that as a value as another Type (the else in the 
source code) when I do annotation.getFeatureValueAsString(feature) to 
print the values associated with the feature of this "inside" Type all I 
get is an empty String (not an error or a null value).

Is there a problem in my code or the error is somewhere else?

Thanks
