<p><strong>My Extjs checkcolumn view</strong></p>

<p><strong>My code snippet</strong></p>

<pre><code>            columns: [{
                xtype: 'treecolumn',
                header: 'Name'
            }, {
                xtype: 'checkcolumn',
                header: 'Check',

                listeners: {
                    checkchange: function(node, checked, eOpts) {
                        // console.warn(JR.app.globalObj.treeNodeSet);
                        console.info(node);
                    }
                }
            }]
</code></pre>

<p><strong>In checkcolumn listeners</strong></p>

<pre><code>listeners: {
    checkchange: function(node, checked, eOpts) {
        console.info(node);
        // NO IDEA which node was checked
    }
}
</code></pre>

<p>No idea which node was checked, How can I do ?</p>
