Description (last modified by bill)

This is fallout from #5865.

In Dojo 1.1, _Widget.getDescendats() searches widgets off "containerNode", which did under "domNode" in 1.0.

 getDescendants: function(){
  // summary:
  // Returns all the widgets that contained by this, i.e., all
widgets underneath this.containerNode.
   var list= dojo.query('[widgetId]', this.containerNode);
   return;  // Array
   return [];

This change causes destroyDescendants() not working for some layout widgets, as they do not set "containerNode"...

While, _Container.getChildren() still does access domNode:

 getChildren: function(){
  // summary:
  //  Returns array of children widgets
  return dojo.query("> [widgetId]", this.containerNode || this.domNode).map(dijit.byNode); // Array

Maybe can add this to _Container.postCreate():

   this.containerNode = this.domNode;

and then modify getChildren() and friends to use this.containerNode exclusively.

Note that getDescendants()/destroyDescendants() on a plain widget with widgets in it's template but no true descendants should do nothing; need to make sure that the widgets in the template aren't destroyed in that case either.
