    [FIXED-EXTJSIV-158] Dynamic Form, Grid and Charts example stall 1+ second


    If you edit a number in the form, like putting 50, then do backspace, it's freezing for at least 1 second on a quad core. Looks like there is too much looping and no "idle" time left for user action.

    It's currently designed that way (though I'd prefer a smaller buffer):

    Code:
            createListeners = function() {
                var timer = null;
                return {
                    change: function(field, newValue, oldValue, listener) {
                        var name, series;
                        if (selectingRow) return;
                        clearTimeout(timer);
                        timer = setTimeout(function() {
                            form.updateRecord(rec);
                            updateRecord(rec);
                        }, 1000);
                    }
                };
            };
    I'm going to clean this up a bit and lower the delay.

    Code:
            createListeners = function() {
                return {
                    change: function(field, newValue, oldValue, listener) {
                        if (selectingRow) {
                            return;
                        }
                        form.updateRecord(rec);
                        updateRecord(rec);
                    },
                    buffer: 250
                };
            };
