I have built an AIR app using ColdFusion 8.01 as the backend. I am getting this error occasionally on Remote Object calls. My suspicion is that the Channel being used by the RemoteObject is timing out. I'm not bothering to configure the Channel separately, I'm just going with the default that is part of the RemoteObject.
I'm using Cairngorm, with a ServiceLocator and my thought is that I could separately define my channel from the RemoteObject declaration and listen for timeout events on the Channel and refresh the Channel if it times out.
I'd be really interested in anyone's feedback on this issue.
