When I create an element with the DOM (or even with Ext functions) and I add it to my Ext container (or Component...), it seems to always create an id in the HTML code. But I don't want those dirty IDs.
For instance, here is how I create a bold style on the selected text :
var range = window.getSelection().getRangeAt(0);
var b = document.createElement('b');
Notice, that I do not use any Ext JS functions here.
But the element is contained in an element created by Ext JS...
