Re: context in visitors - smallwiki

12 May 2005

...
  We are trying to hide objects from the user via an
escaping  
 visitor. Our
 first idea was something like:

 SW2Visitor>>visitSecurityDecoration: aSecturityDecoration
     (self context isCurrentUserAllowedTo: aSecturityDecoration parent)
         ifFalse: [ self escape ] 
Yep, that would be the idea.

...
  The problem is that that
 SW2CurrentContextHolder value
 is sometimes nil, eg for SW2PathLookup.

 Any ideas? 
What about setting it in SW2Visitor and make sure that all subclasses  
do a propre super call? I think the default ones should do this anyway.

Cheers,
Lukas
