Hello guys!
I have noticed something very very weird.

I have a GridPanel (it contains GroupingStore && GroupingView) with an id "myID".
If I call Ext.getCmp('myID').destroy(); and then call Ext.getCmp('myID'); it returns nothing as it is obvious.

BUT

If I group by any column first then call Ext.getCmp('myID').destroy(); and THEN Ext.getCmp('myID'); it returns a component!!!!!!! without a body DOM.

I consider if grouping forces an internal state of a component????

Any help is desirable because I've reached to a dead-lock!!!!!
