Worklight : 어댑터 내부에서 재귀 함수 호출 - Studio를 중단합니다.

Question

아래의 간단한 함수가 있는데, 앱에서 호출 할 때 WL Studio가 중단되고 재귀 예외가 발생합니다.

어댑터 기능

function listSummaries3009Details(param){ 
     var obj = com.MQNotifier.SimplePTP(); 
     var result = obj.getListSummaries3009(param) ; 
     WL.Logger.debug("inside adapter :" + result); 

     var xmlDoc = new XML(result); 
    return { result : xmlDoc }; 
} 

예외 : 나는 아래처럼 위의 어댑터 기능을 실행하면

이제 다음은 잘 작동합니다.

function listSummaries3009Details(param){ 
     var obj = com.MQNotifier.SimplePTP(); 
     var result = obj.getListSummaries3009(param) ; 
     WL.Logger.debug("inside adapter :" + result); 

     var xmlDoc = new XML(result); 
    return { result : result }; 
} 

이 문제를 해결하려면 어떻게 하시겠습니까?

감사합니다.

재귀를 막을 방법이 없습니다. 이것은 코드의 버그입니다. 함수를 시작하려면 함수의 시작 부분에 뭔가가 있어야합니다.
