[Seaside] Updating non Smallfaces component.

[Timothy James Ziebart]

Hi Juan,  thanks for responding. 

The google map is an object that implements a renderOn method.  It is 
the GoogleMaps package by James Foster.  
http://seaside.gemstone.com/ss/GoogleMaps. 

I have created WAComponent and non WAComponent versions.  I do not have 
a SmallFace equivalent widget.   Maybe that is my question - is it 
possible to build a SmallFaces widget that will take advantage of the 
features available?
