Issue with Xcode 4.5.2

Hi,

I was trying out MacMapKit today and I noticed something odd. With Interface Builder in Xcode 4.5.2, if I change a custom view to a MKMapView and leave the IBOutlet in my view controller disconnected in IB, I get the map view just fine.

However, if I connect the IBOutlet in IB, I get these error messages:

2013-01-12 19:49:28.455 Envisage Mac[13536:303] -[WebUndefined MKJSONValue]: unrecognized selector sent to instance 0x101b1fc70
2013-01-12 19:49:28.456 Envisage Mac[13536:303] -[WebUndefined MKJSONValue]: unrecognized selector sent to instance 0x101b1fc70

and my entire window is just showing nothing (e.g.: all views seem to not be displayed at all). Has anyone seen this before? I would love to use MacMapKit in my current project, but I can't seem to find a solution here.

Cheers,
Greg
