Is there a way to make kendo.observable set up non enumerable properties from the object you give it?  For example:

var someObject = {};
someObject.x = 5;
Object.defineProperty(someObject, "someString", {
    enumerable: false,
    configurable: false,
    writable: true
});
someObject.someString = "This is the base";
 
var foo = kendo.observable(someObject)
 
"x" in foo;  //true
"someString" in someObject;  //true
"someString" in foo;  //false, but I want this to be true

Hi Chris,

the kendo observable call uses enumeration to iterate through the passed object properties - the code can't actually "figure out" that someString is present. A thing which comes to mind is to define the property to the observable result - I am not sure if this makes sense in your scenario, though.
