    Hi Vadym,

    I think this is an issue:
    item.setChecked(true, true);
    Please clarify why do suppress events?

    This appears to help remedy the problem.
    item.setChecked(true);

    Thanks much for the tip Daniil! I need to suppress events to avoid firing filter's Update and Activate unnecessarily. I handle these events separately when they're user triggered. If I remove the second parameter from the setChecked() call, the error I've reported indeed disappears but I'm not sure if it will serve to meet my requirements.

    Hello!

    You suppress updating of filter's values so you have to update them manually:

    var applyFilters = function (grid) {
        var today = new Date();
        var beforeValue = new Date();
        var afterValue = null;
        var onValue = null;
    
        beforeValue.setDate(today.getDate() - 10);
        //afterValue.setDate(today.getDate() - 10);
    
        grid.filters.filters.each(function (filter) {
            filter.suspendEvents(false);
    
            filter.menu.items.each(function (item) {
                if (item instanceof Ext.menu.CheckItem) {
                    var itemText = item.text.toLowerCase();
                    var picker = filter.getPicker(itemText);
                    switch (itemText) {
                        case "before":
                            if (isDate(beforeValue)) {
                                picker.setValue(beforeValue);
                                item.setChecked(true, true);
                                filter.values["before"] = beforeValue;
                            }
                            break;
                        case "after":
                            if (isDate(afterValue)) {
                                picker.setValue(afterValue);
                                item.setChecked(true);
                                filter.values["after"] = afterValue;
                            }
                            break;
                        case "on":
                            if (isDate(onValue)) {
                                picker.setValue(onValue);
                                item.setChecked(true);
                                filter.values["on"] = onValue;
                            }
                            break;
                    };
                }
            });
    
            filter.setActive(true);
            filter.resumeEvents();
        });
    };

    Thanks for your help Daulet, Daniil! After adding this line

    filter.values["before"] = beforeValue;
    the error is no longer reproducible in my setup. Please mark this thread as closed.
