example code may look like:

SetDataModel:

 public class SetDataModel extends ListDataModel {
 
  public SetDataModel() {
  super();
  }
 
  public SetDataModel(Set set) {
  super();
  List list = new ArrayList(set);
  setWrappedData(list);
  }
 }


change com.icesoft.faces.component.panelseries.UISeries to:

 private DataModel getDataModel() {
          if (null != this.dataModel) {
              return (dataModel);
          }
  
          Object currentValue = getValue();
  
          if (null == currentValue) {
              this.dataModel = new ListDataModel(Collections.EMPTY_LIST);
          } else if (currentValue instanceof DataModel) {
              this.dataModel = (DataModel) currentValue;
          } else if (currentValue instanceof List) {
              this.dataModel = new ListDataModel((List) currentValue);
          } else if (Object[].class.isAssignableFrom(currentValue.getClass())) {
              this.dataModel = new ArrayDataModel((Object[]) currentValue);
          } else if (currentValue instanceof ResultSet) {
              this.dataModel = new ResultSetDataModel((ResultSet) currentValue);
          } else if (currentValue instanceof Result) {
              this.dataModel = new ResultDataModel((Result) currentValue);
          } else if (currentValue instanceof TreeModel) {
              this.dataModel = new TreeDataModel((TreeModel) currentValue);
          } else if (currentValue instanceof Set) {
              this.dataModel = new SetDataModel((Set) currentValue);
          } else {
              this.dataModel = new ScalarDataModel(currentValue);
          }
  
          return (dataModel);
 }
