I wrote a custom away command, and I have a call to handleResponse at the end. This is usually not called - I can't detect the pattern of when it is and when it isn't. Usually it isn't. It worked for a while, then I made some changes that had nothing at all to do with this, and now it's never called.
There's nothing wrong with the structure of the call - I haven't changed it from when it did work. And there is nothing wrong with the customization of handleResponse that includes the case of this custom command.
I can see in the trace that it's simply not called.
