Cannot call method 'substring' of undefined

Question

Here is my code:

Ext.define('Ext.app.Portal', {
    extend: 'Ext.container.Viewport',

    uses: ['Ext.app.PortalPanel', 'Ext.app.PortalColumn', 'Ext.app.GridPortlet', 'Ext.app.ChartPortlet'],

    getTools: function () {
        return [{
            xtype: 'tool',
            type: 'gear',
            handler: function (e, target, panelHeader, tool) {
                var portlet = panelHeader.ownerCt;
                portlet.setLoading('Working...');
                Ext.defer(function () {
                    portlet.setLoading(false);
                }, 2000);
            }
        }];
    },

    initComponent: function () {
        var content = '<div class="portlet-content">' + Ext.example.shortBogusMarkup + '</div>';

        Ext.apply(this, {
            id: 'app-viewport',
            layout: {
                type: 'border',
                padding: '0 5 5 5'
            }, //eo layout
            items: [{ //app-header : item 1 of app-viewport
                id: 'app-header',
                xtype: 'box',
                region: 'north',
                height: 40,
                html: 'My Portal'
            }, { //container : item 2 of app-viewport
                xtype: 'container',
                region: 'center',
                layout: 'border',
                items: [{ //app-options: item 1 of container

                    region: 'west',
                    animCollapse: true,
                    width: 200,

                        border: false,

                    activeTab: 0,
                    region: 'center',
                    items: [{
                        title: 'tab1',
                        layout: 'column',
                        html: 'this is the first tab',
                        closable: true
                    }, {
                        title: 'tab2',
                        closable: true
                    } //eo tab2
                    ] //eo items tabpanel

                }]
            }] //eo   app-portal
        }); //eo apply

        this.callParent(arguments);
    },

    onPortletClose: function (portlet) {
        this.showMsg('"' + portlet.title + '" was removed');
    },

    showMsg: function (msg) {
        var el = Ext.get('app-msg'),
            msgId = Ext.id();

        this.msgId = msgId;
        el.update(msg).show();

        Ext.defer(this.clearMsg, 3000, this, [msgId]);
    },

    clearMsg: function (msgId) {
        if (msgId === this.msgId) {
            Ext.get('app-msg').hide();
        }
    }

});

Any help would be greatly appreciated.

Answer 1

first... i tried to copypaste your code, and replace it into portal sample,...
i didn't get your error, there is no substring error, but i got error in tabpanel part.. i think, the error is because uses config (this because substrin, can be found in classes.js)..

in portal sample, they use Ext.app.PortalPanel, Ext.app.PortalColumn, Ext.app.GridPortlet,and Ext.app.ChartPortlet,
but in your script you don't use it.. just remove uses part,
you don't need that, you just need tabpanel

second, see classes.js file there is no tabpanel define...
if you want to manipulate the portal without boundaries..
use the ext-all.js instead of ext-core..

change this :

<script type="text/javascript" src="../../builds/ext-core.js"></script>
<script type="text/javascript" src="../shared/examples.js"></script>
<script type="text/javascript" src="classes.js"></script>
<script type="text/javascript" src="portal.js"></script>

to this

<script type="text/javascript" src="../../bootstrap.js"></script>
<script type="text/javascript" src="../shared/examples.js"></script>
<script type="text/javascript" src="portal.js"></script>
