"Pier Unix Security" does not allow you to remove permissions.
If you give some permission to the other permissions, these
permissions will be given to anybody even if the owner or group does
not match. It is kind of hard to explain in a mail, but I think the
code is pretty explanatory:
PUSecurity>>hasPermission: aPermission for: aUser
"Test if the user aUser has the permission aPermission. This is the
central method to test for permissions in Pier."
(aUser notNil and: [ aUser isSuperuser ])
ifTrue: [ ^ true ].
(self owner = aUser and: [ self ownerPermissions includes: aPermission ])
ifTrue: [ ^ true ].
(self group notNil and: [ (self group includes: aUser) and: [ (self
groupPermissions includes: aPermission) ] ])
ifTrue: [ ^ true ].
(self otherPermissions includes: aPermission)
ifTrue: [ ^ true ].
^ false
In your particular case I suggest that use CSS so that when the user
is logged in the other message is hidden below the logged-in DOM
element. Alternatively you can create your own Seaside component,
similar to PUSecurityWidget.

Lawson,
you can do this using +You must log in>value:user|display=+
Combining the standard feature of an alias being displayed for undefined
value links, and the recently added ability to display any arbitrary text
for the link when it is defined (in this case blank). You could also do +You
must log in>value:user|display=You are logged in as {name}+

Thanks, I was trying to use the simplest possible example, however, just to
isolate the issues with permission and display.
In the "real world" case, I'm actually hoping to have the alternatives be
data from my own test avatar showing, or, once someone is logged into the
wiki/blog, they have the option to use an interface to log their own avatar
into second life and observe how things work and even control it in various
ways in the context of the wiki/blog
So what I want to do is a bit more than controlling arbitrary text. I was
hoping for a way to control display of generic components this way, but I'm
not sure if your solution will do that or not.
Thanks for the suggestion.
Lawson
