Changes to model are ignored?

Anyone see this before.

Code:

---



var myFoo = myComponent.getRecord();



myFoo.get('bar'); // gets value of say, 42.

myFoo.set('bar',1);

myFoo.get('bar'); // should return 1, but gives 42 instead.

---

Now if I do this this instead,

Code:

---



myFoo = myStore.getAt(0);



...

---

It then proceeds to store the changes. What.. the.. ?
