[Newbies] Re: if absent put nil (Riaan)

[Zulq Alam]

I would probably do as Klaus suggests but you could also use a cascade 
and then #ifEmpty:. For example:

self workSession attendees
   do: [:each | html text: each person displayString]
     separatedBy: [html text: '; '] ;
   ifEmpty: [html text: 'NO ATTENDEES']	

Note the cascade ";" at the end of the third line. This sends 
#do:seperatedBy: and then sends #ifEmpty: to the collection returned by 
#attendees. Of course, #ifEmpty: and #do:separatedBy: will only do 
something if the collection is either empty or not.

Regards,
Zulq.
