Error handling

When a JavaScript error happens because of server error/incorrect url (500, 404) the only way you would know the reason is by using something like firebug/chrome dev tools (by looking in the console for the execution of ajax requests).

You can also assign a js function to the awe.err, this way whenever an error will occur your custom function will be executed (this code is called in aweUtils.init).
aweUtils.js
awe.err = function (o, p2) {
    var msg = "unexpected error occured";
    if (p2) {
        if (typeof p2 === 'string') {
            msg = p2;
        } else {
            msg = p2.responseText || p2.message || msg;
        }
    }

    var pcon = msg;

    // handle ajax errors that return html with layout page
    if (msg.indexOf && msg.indexOf('<html') > -1) {
        pcon = $('<div>unexpected error<br/> (showing it will replace the whole page)<div/>');
        var btn = $('<a href="">show</a>').click(function (e) {
            e.preventDefault();
            $('html').html(msg);
        });

        pcon.append(btn);
    } else

        if (o && o.id) {
            pcon = o.id + ' ' + msg;
        }

    awem.notif(pcon, 0, 'o-err');

    // close popup that got error
    if (o && o.cx && o.cx.isOpen) {
        dapi(o.d).close();
    }
};
