回调函数未抛出错误时未定义错误

Question

var callback = dojo.lang.hitch(this, this.getCallbackReview); //This is used to call callback funstion after line2
this.service.ReviewManager.getReview(callback, path, ItemPath, true); //use to call java method which returns Pojo

//This is callback function
getCallbackReview: function(info, error) {
    if(error) {
        alert(error); //in case of any error from the java method
        return;
     }
     alert(info); //If no error thrown from Java Method
},

The second is not throwing any error and returning proper info but if this info has clob field then giving me error as undefined.

Answer 1

In this line of code:

var callback = dojo.lang.hitch(this, this.getCallbackReview);

You pass as as scope this.getCallbackReview but this property is not defined in your code snippet. To fix it you should consider adding getCallbackReview as property so

this.getCallbackReview = function(info, error) {
   ...
},

or alternativelly:

var callback = dojo.lang.hitch(this, getCallbackReview);
