OData Read-Callbacks not triggered in UI5 controller

Question

I need a manual OData call from SAPUI5 to my SAP Gateway (without data binding).

For that, I'm using the following code:

oModel.read("/ZTestSet"),  
    null,null,false, function(oData, oResponse){
       alert("success");
    },
    function(oError ){
       alert("error");
}

I've debugged it on the SAP system. I received the call and fill the et_entityset with the required data.

The problem is, that no function will be triggered as callback. Neither success nor error (I can't find any error on the gateway or someone else).

Response in Browser's Developer Tools:

Looks like a successful call.

It was a small typo mistake. https://stackoverflow.com/a/36442942/5846045 Can be closed. — Boghyon Hoffmann, Jan 15 '21 at 17:57

place the below debuger line in both the success and error calls and see if it triggers in the browser. oModel.read is an asynchronous call meaning it doesn't wait for the response and triggers the success or error method only after it receives either of the response from the server. So if you are waiting then it might look like nothing's happening.

              debugger;

It´s an asynchronous call, yes i know. I also tried it with the ´debugger´ statement, but even so it will not be triggered after several minutes. – alexander-fire Apr 06 '16 at 06:09

What a silly mistake.

I closed the parenthesis after the URL. It should be closed naturally after the last parameter. In my case after the error-function.

Right code:

oModel.read("/ZTestSet", null, null, false, function(oData, oResponse) {
  alert("success");
}, function(oError){
  alert("error");
});
