How to get the element type of a uima.cas.FSList feature

                 Key: UIMA-1208
                 URL: https://issues.apache.org/jira/browse/UIMA-1208
             Project: UIMA
          Issue Type: Bug
          Components: Core Java Framework
    Affects Versions: 2.2.2
         Environment: Fedora 9
            Reporter: Manuel Fiorelli
            Priority: Minor

The documentation 


states that in the type system descriptor one may use <elementType> to constraint the
type of elements in both array and list features.

However, if one gets the type system of a CAS [myCas.getTypeSystem()],
1) if the feature range is an array, he can retrieve the element type through the method Type.getComponentType()
2) if the feature range is a list, there seems not to be any way to get the element type,
since the method Type.getComponentType() returns null
