Hi Mariano,

In my environment I am able to subclass the standard renderers,
including the PRReferenceRenderer

in my subclass I add the following, and it works much better than making
a special component for every message that you want to give the user
saying "please log in".

Keith

visitInternalLink: aLink

((link hasParameter: 'loggedout') and: [component context isLoggedIn
]) ifTrue: [ ^ self ].
((link hasParameter: 'loggedin') and: [component context isLoggedIn
not ]) ifTrue: [ ^ self ].

(aLink hasParameter: 'button') ifFalse: [ ^ super visitInternalLink:
aLink ].

html form: [
html button
attributes: (self attributesFor: aLink);
class: 'internal';
title: aLink title;
goto: (self contextForInternalLink: aLink);
with: [ self visitLink: aLink ]

]

Keith: thanks for the help. I have Beach in mind and I was going to take ideas or just adapt it to run in pharo. At least for the thing I need right now.

Now I know where to start from.

Thanks again.

Mariano
