    Default Unanswered: Cannot read property 'isComponent' of undefined

    Hi, I have the following problem:
    Code:
    Ext.define('app.view.Rubs.TreeStore', {    extend: 'Ext.data.TreeStore',
        requires: ['app.model.Rubs.RubModel'],
        model: app.model.Rubs.RubModel,
        folderSort: true,
        constructor: function(cfg) {
            var me = this;
            cfg = cfg || {};
            me.callParent([Ext.apply({
            proxy: {
                        type: 'ajax',
                        api: {
                            read: BaseURL+'server/Rubs/readRub.php',
                            create: BaseURL+'server/Rubs/createRub.php',
                            update: BaseURL+'server/Rubs/updateRub.php',
                            destroy: BaseURL+'server/Rub/deleteRub.php'
                        },
                        reader: {
                            type: 'json'
                        },
                        writer: {
                            type: 'json',
                            writeAllFields: false
                        },
                        listeners: {
                            exception: function(proxy, response, operation){
                                Ext.MessageBox.show({
                                    title: 'Error',
                                    msg: 'CODE 1001',
                                    icon: Ext.Msg.INFO,
                                    buttons: Ext.Msg.OK
                                });
                            },
                        }
            }
            }, cfg)]);
        }
    });
    ----------------------------------------
    Code:
    Ext.define('app.view.Rubs.TreePanel', {
        extend: 'Ext.tree.Panel',
                id: 'TreePanel',
                title: 'Categories',
                width: 500,
                height: 300,
                collapsible: true,
                closable: false,
                useArrows: true,
                rootVisible: false,
                store: new app.view.Rubs.TreeStore(),
                multiSelect: true,
                singleExpand: false,
                stateful: true,
                autoscroll: true,
                columns: [{
                    text: '#',
                    sortable: true,
                    dataIndex: 'id',
                    width: 30
                },{
                    xtype: 'treecolumn',
                    text: 'title',
                    flex: 2,
                    sortable: true,
                    dataIndex: 'title',
                    editor: {
                        allowBlank: false
                    }//end editor
                }]
        });
    I'm doing and I get an error...

    Code:
    ...
    region: 'center',
    xtype: 'tabpanel',
    items:[new app.view.Rubs.TreePanel()]
    ...
    Help please! Thanks

    You shouldn't create an instance and place it on the prototype like that.

    If you still need help could you please post the full stacktrace, including line numbers, plus details of exactly which ExtJS version you're using so that we can cross-reference the stacktrace?

    I would also strongly recommend you to try simplifying your test cases before posting to the forums. Most of the config options you've specified on your tree could be safely removed and it would make it much easier to try to isolate the actual cause of the problem.
