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

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.

I have the following code

renderAttendeesOn: html self workSession attendees do: [:each | html text: each person displayString] separatedBy: [html text:'; '.]

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

Please assist.
