OData create request body malformed

Hello everyone,

i am currently developing an SAPUI5 application which is accessing an OData service exposed by Java Olingo framework. The odata service is fine and i am also able to retrieve entities from the the service. However, i am still struggling to insert something.

I have one entity Customer with two nagivation properties to Title and Country. In the SAPUI5 i create the payload as follows:

var payload = {  ID: nID,  CDate: new Date(),   UDate: new Date(),   CustomerNumber: customer.CustomerNumber,   Prename: customer.Prename,   Surname: customer.Surname,   Birth: customer.Birth,   PhoneNumber: customer.PhoneNumber,   FaxNumber: customer.FaxNumber,   Street: customer.Street,   StreetNumber: customer.StreetNumber,   AdditionalText: customer.AdditionalText,   ZipCode: customer.ZipCode,   City: customer.City  };  payload.Title = {  __metadata: {  uri: this.getView().byId("selectTitle").getSelectedItem().getBindingContext().getPath()  }  };  payload.Country = {  __metadata: {  uri: this.getView().byId("selectCountry").getSelectedItem().getBindingContext().getPath()  }  };   console.log(JSON.stringify(payload));  var oData = this.getODataModel();  oData.create("/Customer", payload, null,  jQuery.proxy(this.onCreateSuccessPopUp, this),   jQuery.proxy(this.onCreateFailPopUp, this));

The resulting payload in Json looks as follows:

{

"ID":0,

"CDate":"2015-10-15T15:45:19.176Z",

"UDate":"2015-10-15T15:45:19.176Z",

"CustomerNumber":"54433422",

"Prename":"Test",

"Surname":"Test",

"Birth":"2015-10-14T22:00:00.000Z",

"PhoneNumber":"123456789",

"Street":"Test",

"StreetNumber":"14",

"ZipCode":"50126",

"City":"Bergheim",

"Title":{"__metadata":{"uri":"/Title(1L)"}},

"Country":{"__metadata":{"uri":"/Country(1L)"}

}}

The error from the odata looks as follows:

HTTP request failed400,Bad Request,{"error":{"code":null,"message":{"lang":"en","value":"The request body is malformed."}}}

Somebody know how to fix it? For the OData object i tried both version (v2.ODataModel and ODataModel).

Hope somebody can help me.

Thanks

Best regards,
