OdataModel as named Model and databinding

[b_deterd2]

Hello,

When we create an odatamodel (not a named model), the textfield in the view is populated with a value. So everything works fine.

However when we create the odatamodel as a named model there seems to be no way to do a property binding.

Let me give you an example with the "http://services.odata.org/Northwind/Northwind.svc/" service .

Controller:

 var oModel = new sap.ui.model.odata.ODataModel("http://services.odata.org/Northwind/Northwind.svc/");
  sap.ui.getCore().setModel(oModel);

View:

var oTf = new sap.ui.commons.TextField('input1');
  oTf.bindElement("/Categories(1)"); 
  oTf.bindProperty("value", {
     path: "CategoryName"
  });
  return oTf;

However : when we want the odatamodel to be a named model, the value in the textfield is not populated anymore.

Controller:

  var oModel2 = new sap.ui.model.odata.ODataModel("http://services.odata.org/Northwind/Northwind.svc/");
  sap.ui.getCore().setModel(oModel2, "testModel");

View:

  var oTf = new sap.ui.commons.TextField('input1');
  oTf.bindElement("/Categories(1)"); 
  oTf.bindProperty("value", {
      path: "CategoryName",
      model: "testModel"
  });
  return oTf;

We tried several settings with path like testModel>/Categories(1) but no luck.

Could anyone tell us how to use the oDataModel as a named model with regards to property binding?

Any help will be appreciated.

Hi Bert,

please try the following:

var oTf = new sap.ui.commons.TextField('input1'); 
oTf.bindElement("testModel>/Categories(1)");  
oTf.bindProperty("value", "testModel>CategoryName"); 
return oTf;

Stefan is right.

If you use named models, always remember to prefix any bound value/element/property with the correct named model too.
