    extend: 'Ext.tree.Panel',
    alias: 'widget.example',
    title: 'example',
    store: Ext.create('Ext.data.TreeStore', {
    ...
    listeners: {
        'load': function (store, records, success) {
            Ext.ComponentQuery.query('example').getEl().unmask(); // not working
        },
        'beforeload': function (store, options) {                                    
            Ext.ComponentQuery.query('example').getEl().mask();// not working

EIther use the undocumented ownerTree property:

beforeload: function() {
    this.ownerTree.getEl().mask("Loading", 'x-mask-loading');
}

Or register your listeners in a method in order to get the scope:

Ext.define('Example.example', {
    // ...
    ,initComponent: function() {
        this.callParent(arguments);

        this.getStore().on({
            scope: this
            ,beforeload: function() {
                this.getEl().mask("Loading", 'x-mask-loading');
            }
        });
    }
});

try this one Ext.ComponentQuery.query('example').body.mask(); use body instead of getEl()
