Fixed version (ground truth):

        basePropertyParameter=param;
        break;
      }
    }
  }
  String repositoryType=null;
  if (basePropertyParameter != null) {
    repositoryType=(String)basePropertyParameter.getChildParameters().get(EParameterName.PROPERTY_TYPE.getName()).getValue();
  }
 else {
    repositoryType=(String)elem.getPropertyValue(EParameterName.PROPERTY_TYPE.getName());
  }
  String propertyName=(String)openSQLEditorButton.getData(PARAMETER_NAME);
  String query=(String)elem.getPropertyValue(propertyName);
  ECodeLanguage lang=LanguageManager.getCurrentLanguage();
  if ((!TalendTextUtils.isCommonString(query) || QueryUtil.checkIfHasSpecialEscapeValue(query) || QueryUtil.checkIfIsNoQuotesAtAll(query)) && (lang == ECodeLanguage.JAVA)) {
