Unable to get el element for Ext.Component

GraphReportPanel = function (config, initData) {
GraphReportPanel.instance = this;


this.graphPanel = new Ext.Container({
    id : 'graphPanelId'
});

GraphReportPanel.superclass.constructor.call(this, {
    title : 'Graph',
    autoScroll: true,
    id : 'graphReportPanel',
    items: [this.graphPanel],
    collapsible : false
});

};

I have created GraphReportPanel . Now when i use the following code 

Ext.getCmp('graphPanelId').el.dom.innerHTML = '';

I get Ext.getCmp('graphPanelId').el as undefined . Why is it so?

getEl() returns the dom element only if your component is rendered. Please check if the component is rendered before you call this method.

Hope it helps.

Use Ext.getCmp('graphPanelId').getEl() instead of Ext.getCmp('graphPanelId').el.

More information in this topic : Can you please explain .el, getEl(), Ext.get() in detail?
