updateActionListener questions (re: Shale Clay mostly)

[Richard Wallace]

I'm trying to make use of the Tomahawk updateActionListener action 
listener in a Shale Clay based app and was having problems getting it to 
work properly.  After doing some debugging I realized that the problem 
was that I was trying to map to the property "property" on the 
UpdateActionListener class thinking that the tag "property" attribute 
just passed the value through. 

On closer inspection I realized this isn't the case and that the 
UpdateActionListenerTag itself takes the value set for the "property" 
attribute and creates a value binding which is passed to the 
UpdateActionListener with the setPropertyBinding() method.  Similarly, 
the UpdateActionListenerTag also figures out if the "value" attribute is 
supposed to be an actual value object or a value binding.

I searched this list and this was also a problem when trying to 
integrate with Facelets.  So my question is why is all this work done in 
the UpdateActionListenerTag class instead of in the UpdateActionListener 
class itself?  Then the tag class would just pass the values through 
like all the other tags in JSF.
