I’m working on a page behavior of my own and I’ve looked briefly at the  
delegation mechanism. Would I be correct in assuming that any method  
that  
is available to a Page is available in the Behavior methods that are  
delegated to? Specifically, I’d like to be able to manipulate the page,  
its  
parts and its children.

No. Pages currently delegate the following methods to a behavior:

delegate\_to :behavior, :url =\> :page\_url, :cache? =\> :cache\_page?,  
:find\_by\_url =\> :find\_page\_by\_url, :render =\> :render\_page,  
:virtual? =\> :page\_virtual?

delegate\_to :behavior, :process, :child\_url

Not sure what you are doing, but you may end up having to override  
existing tags in order to get it to work. Behaviors are due for a  
refactoring.

Well, maybe I could put it this way… is there a way to determine the  
page being processed from the request object passed to process\_page?  
All I need is to get an instance of the page, then I’ll be able to  
manipulate it however I like.

P.S. Ok, ok, so I’ll spill the beans. I’m working on a behavior(s) that  
will allow comments to be posted as new (grand-)child pages.

You can change the find\_page\_by\_url method.
