Clearing the content of a panel, which is rendered on another panel

[kislay.kishore]

I have two questions:
1. How to clear the content which is rendered on rawDataContainer and chartContainer. My code for the panel (with border layout ) is as below.

2. I am using 'rawDataContainer-body' and 'chartContainer-body' and passing it in renderTo of concered chart and grid panel. I found in firebug, that ExtJS creates such div (panelId-div) . This doesnt seems to best practice to me. Is there any other way to get these div Ids?

Please suggest. Thanks!

var myPanel = Ext.create('Ext.panel.Panel', {
    height: 800,
    title: 'HomePage',
    layout: 'border',
 defaults: {
    collapsible: true,
    split: true,
    bodyStyle: 'padding:15px'
 },
    items: [{
        title: 'Raw Data',
  id: 'rawDataContainer',
        region: 'south',   
        xtype: 'panel',
  //layout: 'fit',
        height: 300,
        split: true,       
        margins: '0 5 5 5'
    },{
        title: 'Input',
        region:'west',
        xtype: 'panel',
        margins: '5 0 0 5',
        height: 500,
  width: 450,
        collapsible: true,  
  collapseDirection: 'top',
        id: 'inputContainer',
       layout: 'fit'
    },{
        title: 'Chart',
        region: 'center',    // center region is required, no width/height specified
        xtype: 'panel',
        layout: 'fit',
  height: 500,
        margins: '5 0 0 0',
  id: 'chartContainer',
    }],
    renderTo: 'pageDiv'
});

How about the following code?

var rawDataPanel = Ext.getCmp('rawDataContainer');
rawDataPanel.removeAll();

It doesnt work. However, I didint get any error either...

How about the following code?

var rawDataPanel = Ext.getCmp('rawDataContainer');rawDataPanel.removeAll();

Also add the following line at the end.

rawDataPanel.doLayout();

If that doesn't work, can you try printing out rawDataPanel to console and check in firebug?

[kislay.kishore]

It doesnt remove. On cosole, it does show two objects for rawDataPanel on firing the request for the second time.

I went thru the code for removeAll() , wondering why this code is not working, although it seems to be correct!

Did you read my second question? Can it cause the issue here?
