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.

if there is no attendees for my worksession, it needs to display : NO
ABSENTEES.
Please assist.
