2.1.0-rc2 NestedList Grouped and Grouper no longer work

[drb]

Touch 2.1.0-rc2

In 2.0.1.1 in the NestedList listchange event it is possible to set up a Grouped on the List and a Grouper on the list.getStore().

This no longer works in 2.1.0-rc2

Ext.setup({
    onReady: function () {

        var data = {
            text: 'Groceries',
            items: [{
                text: 'Drinks',
                gp: 'D',
                items: [{
                    text: 'Water',
                    gp: "W",
                    items: [{
                        text: 'Sparkling',
                        gp: "S",
                        leaf: true
                    }, {
                        text: 'Still',
                        gp: "S",
                        leaf: true
                    }, {
                        text: 'Deep',
                        gp: "D",
                        leaf: true
                    }, {
                        text: 'Muddy',
                        gp: "M",
                        leaf: true
                    }]
                }, {
                    text: 'Ale',
                    gp: 'A',
                    leaf: true
                }]

            }, {
                text: 'Lager',
                gp: "L",
                leaf: true
            }]
        };

        Ext.define('ListItem', {
            extend: 'Ext.data.Model',
            config: {
                fields: [{
                    name: 'text',
                    type: 'string'
                }, {
                    name: 'gp',
                    type: 'string'
                }]
            }
        });

        var store = Ext.create('Ext.data.TreeStore', {
            model: 'ListItem',
            defaultRootProperty: 'items',
            root: data
        });

        var nestedList = Ext.create('Ext.NestedList', {
            fullscreen: true,
            title: 'Groceries',
            displayField: 'text',
            store: store,
            listeners: {
                listchange: function (nlist, list) {
                    var liststore = list.getStore();
                    liststore.setGrouper({
                        groupFn: function (record) {
                            return record.get("gp");
                        }
                    });
                    list.setGrouped(true);
                }
            }

        });
    }
});
