Using Ext JS 5.1.1.215, I can end-up in the following code with Ext.EventObject == undefined:

I'm guessing that checking for null for Ext.EventObject would be a good workaround.



Code:



Ext.define('Ext.view.BoundList', {
    extend: 'Ext.view.View',
...
onHide: function() {
        var inputEl = this.pickerField.inputEl.dom;


        // If we're hiding a focused picker, focus must move to the input field unless the instigating
        // browser event is a touch. In that case, the input only focuses when they touch it -
        // we want to avoid an appearing keyboard.
        if (Ext.Element.getActiveElement() !== inputEl && Ext.EventObject.pointerType !== 'touch') {
            inputEl.focus();
        }
        // Call parent (hide the element) *after* focus has been moved out.
        // Maintainer: Component#onHide takes parameters. 
        this.callParent(arguments);
    }
