This means, "self" above, does not have a method "getPhysicalRoot".

This may be because it is only partially acquisiton wrapped.

   Usually, you should check for attribute existence with "aq_base"
   but access without the "aq_base".

   I.e., you should use the following idiom:

	 if hasattr(aq_base(obj),'some_attribute'):
	   my_attribute= getattr(obj,'some_attribute')
	   ...
