Hi,

I'm developing server side for Anatoly's iOS client, and our Metadata adapter is receiving empty string for user parameter when iOS sends nil (it receives char $, which is supposed to be encoding for empty string). On the other hand, javascript client correctly sends null (char #) when user is not set on connectionDetails.

We've adjusted our Metadata adapter to treat $ as null strings, solving our problem, but I believe there's a bug in iOS client library that causes this.

BR,
Dejan
