"Is it a non-200 status code"
I can't say it's 100% of the time, but in my code it seems to be the
case
this code:
function reqJSON(url, params, success, error) {
var CallParams = {};
CallParams.type = params.Method || "POST";
CallParams.url = url;
CallParams.processData = true;
CallParams.data = params;
CallParams.dataType = "json";
CallParams.success = success;
if (error) {
CallParams.error = error;
}
$.ajax(CallParams);
}
goes into the error event if a 500 status code is encountered during
the process
