Cannot use 'in' operator to search for 'id' in text

[jaysshortt]

Hi,

I can't seem to work out why the following code is throwing an error:

it('Attributes can be set on the model instance when it is created.', function() {
    var todo = new Todo({ text: 'Get oil change for car.' });
    var expectedText = 'FIX ME';
    todo.set('text',"FIX ME");
    expect(expectedText).toEqual(todo.get('text'));
});

The console states: TypeError: Cannot use 'in' operator to search for 'id' in text -> koans/aboutModels.js:24

Any idea where I've gone wrong?

Thanks

Hmmm I've just tried changing

todo.set('text',"FIX ME");

to

todo.set({'text':"FIX ME"});

which works! But why doesn't the origina statement work? Backbone.js' website actually states that the following should work?

book.set("title", "A Scandal in Bohemia");

Any help would be gratefully received.
Thanks
