Handle Connection Error when calling seam remote function in javascript

Question

I use seam 2 with javscript remote object and it works fine but I wonder how to handle if the server is unavaible. Currently it display an 503 error on a javascript popup, which is quite awful.

i tried

try {
    var remoteObject= Seam.Component.getInstance("remoteObject");
    if(remoteObject){
        sessionChecker.remoteFunction(parameter, functionCallBack);
    }else{
        alert('error');
    }
} catch(err) {
    alert('error');
}

but without success -> still the annoying default popup.

Either patch file attached in issue or use at least Seam 2.2.2.
