HTTP Post Error: Changeset processing failed

[TimMuchena]

Hi

I am getting Changeset processing failed error message even though i am not doing a batch call. My understanding is that you get this error if something goes wrong when doing a batch request. Maybe i am wrong

var oCountry = this.byId("Country").getValue();

  var oCity = this.byId("City").getValue();

  var oPopulation = this.byId("Population").getValue();

  var oProperties = {

                 Country: oCountry,

                 City: oCity,

                 Population: oPopulation

  };

  var oModel = this.getModel();

  var oContext = oModel.createEntry("/popSet",

                                          { properties: oProperties,

                                            success: this._onCreateSuccess.bind(this)

                                          });

  this.getView().setBindingContext(oContext);

  oModel.submitChanges();

What am I missing?

Thanks

Hello,

By Default the Odata V2 model has batch mode set.

Also from the sourcecode it is evident that you are using batch request from UI (Submit changes is used to submit a batch request with one or more operations).

If you do not want to implement batch(which you should think twice as why you don't want) you can disable it with below code -

oModel .setUseBatch(false);

Then call the createEntry method.

Thanks for educating me. Got some light now

Hi Timothy,

Check the solution here since you are using a number in one of the request fields (potential conversion issue) but Ankit is right that the default processing is to use batch mode for the v2 ODataModel.  You can use the method call to disable batch mode or you can also put this in your manifest.json for when it is instantiated:

"myModel": {
     "dataSource": "myService",
     "settings": {
          "useBatch": false
     }
}
