  remainDBTypeListAF.addAll(allDBTypeList);
  remainDBTypeListCM=new ArrayList<String>();
  remainDBTypeListCM.addAll(allDBTypeList);
  initTempExpressionMap();
  if (widgetMap == null) {
    widgetMap=new HashMap<CCombo,Composite>();
  }
 else {
    widgetMap.clear();
  }
  definition=(IndicatorDefinition)getCurrentModelElement(getEditor());
  if (definition != null && definition.getCategories().size() > 0) {
    category=definition.getCategories().get(0);
  }
 else {
    category=DefinitionHandler.getInstance().getUserDefinedCountIndicatorCategory();
  }
  if (definition != null) {
    hasAggregateExpression=definition.getAggregate1argFunctions().size() > 0;
    hasDateExpression=definition.getDate1argFunctions().size() > 0;
