使用Edm.Time类型的oData模型的PUT方法

Question

i'm trying to implement editable table element with time element (type Edm.Time). the problem comes when changing value in table and application sends PUT request.

the value of time object is for example "PT11H00M00S" and i've assigned type "Edm.Time" via metadata to avoid "Edm.string" comparision problem. but now oData service is SAP shows as per below. how the value should be formatted to avoid this problem? thanks in advance

Answer 1

look like it was problem in __metadata property of context providing to model calls.

              var obj = oSelectedItem.getBindingContext().getObject();
              var context = oEvent.getSource().getBindingContext().getObject();

              context.ldate    = obj.ldate;
              context.ltime    = obj.ltime;

              oController.onRowUpdate("/modelData(pdsnr='"+context.pdsnr+"')", 
                                      context);

now it works as

              var obj = oSelectedItem.getBindingContext().getObject();
              var context = oEvent.getSource().getBindingContext().getObject();

              context.ldate    = obj.ldate;
              context.ltime    = obj.ltime;

              oController.onRowUpdate("/modelData(pdsnr='"+context.pdsnr+"')", 
                                      {ldate:    obj.ldate,
                                       ltime:    obj.ltime,
                                      });
