Question

我在适配器中有以下简单功能，当我从应用程序调用它时，它会挂起WL Studio并提供递归异常。

适配器功能

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 }; 
}

例外：

现在，如果我运行上面的适配器功能，如下所示，那么它可以正常工作。

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 }; 
}

请建议如何摆脱这个？

你无法阻止递归。这是您的代码中的错误。你应该在函数的开头有一些东西来终止它。
