[Seaside] Hierarchy of WAHtmlErrorHandlers

[jtuchel at objektfabrik.de]

Dear Seasiders


I'd like to register a special HTM Error Handler for some Exceptions and 
one for all others.

I've seen there is a class Method #exceptionSelector in WAErrorHandler, 
where you can define the Exceptions that the handler wants to handle.
Of course things are not so easy, because I want one handler for all 
Errors and one for my special exception type, which, of course, is a 
subtype of Error.

Ho do I either

  * Specify an order in which the handlers are tested whether they
    handle: an exception? or
  * Specifiy an ExceptionSet that includes Error and all its children,
    but not my special type?

Any ideas?
