Guys,
I am subclassing a Sencha component ( Ext.Img ) and in one of it's event handlers I am trying to add a child div to the image button

Inside the event handler:
Code:
Ext.DomHelper.append(this.element, {tag:'div',cls:'myCivClass'}, true);
First event trigger goes well and the div is added.

When I move to another view and then re-open the view that have my subclassed image :
I get the following exception:
Code:
INVALID_NODE_TYPE_ERR: DOM Range Exception 2
Has anyone seen this ?
