Created an attachment (id=18002)
 --> (http://issues.apache.org/bugzilla/attachment.cgi?id=18002&action=view)
another approach 

I was looking at the sequence of events that are fired on a postback or
invoking a command (button or link).

VewHandler.restoreView() --> ViewController.init();
ViewHandler.createView() --> ViewController.init();

The logic that tucks away the view controller for the phase listener is invoked
twice and two references to the view controller are added to the list.	This
patch checks to see if a reference exists before it's added.  This would happen
when the target navigation was back to the same page.

Since this is such a core part of Shale, I would like for some feedback before
going further.
