'undefined' is not a constructor

Hi,

Sometimes when i login the application i get this error message :

Code:

---

SyncProxy.js:508TypeError: 'undefined' is not a constructor (evaluating 'newthis.userModel({})')

---

I think that's some kind of race condition during startup. We did fix an error there a while ago. Do you have the latest version of the SIO SDK?

If you could send us more information about how your app starts up that'd be useful.
