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).

Looks like a successful call.

Answer 1

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");
});
