The canonical example of invoking a remote action shows three cases being handled: success, exception, and general failure:

// just showing the handler passed to the remote action invocation, for brevity
function(result, event){
    if (event.status) {
        // do something with result
    } else if (event.type === 'exception') {
        document.getElementById("responseErrors").innerHTML = event.message;
    } else {
        document.getElementById("responseErrors").innerHTML = event.message;
    }
}, 

Every example I've seen handles the else if and else cases identically. I can find no documentation of what values event.type may be when event.status is not true. Is this documented? Is there any reason I should not eliminate the "else if" block, and handle all failures in the same fashion (i.e., log the error)?

Possible Suggestion/Solution #1

I don't usually do the else if and I use a lot of @RemoteAction -- if you haven't handled the error on the server side and returned some useful exception code than there aren't any other known (documented) event.types
