floatingPane throw an exception when destroyed

[guest]

try {
var div = document.createElement("div");
document.body.appendChild(div);
new dojox.layout.FloatingPane({id:"test",title:"title"},div).destroy();
}catch(e){alert(e.message)}

throws an exception : this._underlay has no properties

So the widget is not completely destroyed and stays in the list of widgets.

(In [11621]) fixes #5207 - by removing the underlay and code (i was talked out of ...) added in [11571]. there is a patch coming from BlueFire? to address layout issues.
