I'd like to see a way to trigger Callbacks from the Test Harness. These could be internally tagged for logging, so that they trigger the debugger. Fits well with the existing interface, could be triggered like this { "@class":".LogCallback", "apikey":"","serversecret":"","attr1":"" } and people would just modify according to need.

Hi, not quite what I had in mind. I was talking about artificially triggering the code attached to the >>Callback URL<< for debugging purposes. As the data that would typically come in via the Callback URL is highly asynchronous in nature and it is obviously not possible to start the debugger in realtime on real data coming in.

My original post probably was not clear enough, sorry for that.
