Re: Registering a WARequestHandler

I hit a similar problem when dealing with Files in Magritte/Seaside. I 
kind of (re-)implemented WAApplication>>#urlFor: in my own component 
based on WARegistry>>#urlFor: . Not quite sure if the code is "legal" - 
but it works:

My code in your example might look like this (not tested):

updateRoot: anHtmlRoot
  	| handler |
  	super updateRoot: anHtmlRoot.
  	handler := MySubclassOfWARequestHandler on: self.
         registry := self requestContext registry.
         url := registry url.
         key := registry register: handler.
	registry trackingStrategy addKey: key toUrl: url.
  	

Hope this helps.

CU,

Udo
