    Default Grid reconfigure causes problems

    Grid reconfigure causes problems


    Hi,

    I've found a problem in the grid.reconfigure() method:

    If you do a reconfigure of a grid panel (i.e. reconfigure it with a new store) and then do a revert (i.e. a reconfigure with the initial store) the reconfigure will fail because of this:

    TypeError: me.getStoreListeners is not a function
    (ext-all-debug.js line 41914 - bindStoreListeners method of Ext.util.Bindable)

    The error causes all table headers to disappear and the application is not working anymore.

    TestModel.js:
    Code:
    Ext.define('test.model.TestModel', {
        extend: 'Ext.data.Model',
        fields: [
            { name: 'idfield', type: 'string' },
            { name: 'rating', type: 'int' },
            { name: 'salary', type: 'int' },
            { name: 'name', type: 'string' }
        ],
        
        proxy: {
            type: 'direct',
            directFn: testBufferedStoreSvc.getTestData,
            reader: {
                root: 'records'
            }
        }
    });
    TestStore.js and NewTestStore.js (same stores - different names):
    Code:
    Ext.define('test.store.TestStore', {
        extend: 'Ext.data.Store',
        model: 'test.model.TestModel',
        
        autoLoad: true,
        buffered: true,
        leadingBufferZone: 300,
        pageSize: 100
    });
    TestGridPanel.js:
    Code:
    var myColumns = [
        { text: 'ID', dataIndex: 'idfield', flex: 1 },
        { text: 'Name', dataIndex: 'name', flex: 1 },
        { text: 'Rating', dataIndex: 'rating', flex: 1 },
        { text: 'Salary', dataIndex: 'salary', flex: 1 }
    ];
    
    Ext.define('test.view.grid.TestGridPanel',  {
        extend: 'Ext.grid.Panel',
        alias: 'widget.testgridpanel',
        
        width: 800,
        height: 500,
        title: 'Some random data',
        store: 'TestStore',
        loadMask: true,
        selModel: { pruneRemoved: false },
        plugins: [{ ptype: 'bufferedrenderer' }],
        columns: myColumns,
        
        tbar: ['->',
            {
                xtype: 'button',
                text: 'Reconfigure',
                itemId: 'reconfigure',
                handler: function() {
                    var panel = this.up('testgridpanel');
                    var store = Ext.data.StoreManager.lookup('NewTestStore');
                    store.load();
                    panel.reconfigure(store);
                }
            },
            {
                xtype: 'button',
                text: 'Revert',
                itemId: 'revert',
                handler: function() {
                    var panel = this.up('testgridpanel');
                    var store = Ext.data.StoreManager.lookup('TestStore');
                    store.load();
                    panel.reconfigure(store);
                }
            }
        ]
    });
    Note: the extdirectspring method returns just some random remote test data.

    To reproduce the error just click on the 'Reconfigure' button and then on the 'Revert' button.

    Thanks for your help!

    inline test case:
    Code:
    Ext.define('test.model.TestModel', {
        extend: 'Ext.data.Model',
        fields: [
