      The view page simply iterates over the inputTypes List (I striped out all the other logic to see if there was some other problem


      Here is the backing bean:

      
      @Name("dataSourceMap")
      @Scope(CONVERSATION)
      public class DataSourceMap implements Serializable{
       private static final long serialVersionUID = -4190757500520505242L;
      
       @In
       FacesMessages facesMessages;
      
       @In
       private User user;
      
       @In
       private EntityManager entityManager;
      
       private HashMap<String, List<DataSource>> sourcesByInputType = null;
      
       private HashMap<String, DataSource> sourcesByName = null;
      
       private TreeMap<String, InputType> inputTypesTree = null;
      
       private List<InputType> inputTypes = null;
      
       private HashMap<Integer, InputType> inputTypeById = null;

       @SuppressWarnings("unchecked")
       @Create
       public void init() {
       //initialize datastructures
      ...
       }
      
       public DataSource getDataSourceByName(String name) {
       return this.sourcesByName.get(name);
       }
      
       public List<DataSource> getDataSources(String inputType) {
       return sourcesByInputType.get(inputType);
       }
      
       public InputType getInputById(Integer id) {
       return this.inputTypeById.get(id);
       }
      
       public InputType getInputType(String inputType) {
       return this.inputTypesTree.get(inputType);
       }
      
       public List<InputType> getInputTypes() {
       System.out.println("GETTING INPUT TYPES!");
       return inputTypes;
       }
      
       public void setInputTypes(List<InputType> types) {
       this.inputTypes = types;
       }
      
       public TreeMap<String, InputType> getInputTypesTree() {

       }
      
       public void setInputTypesTree(TreeMap<String, InputType> inputTypesTree) {
       this.inputTypesTree = inputTypesTree;
       }
      }
      



      Any help?
