I just jumped into Seaside and am still collecting basic knowledge.

But I have played around a little with WACounter. If I subclass 
WAComponent as MyClass and render it like this

MyClass>>renderContentOn: html
  waCounterInstance renderContentOn: html

the counter perfectly works. But if I do

  html render: waCounterInstance


  html divNamed: 'counter' with: waCounterInstance

no more changes happen to the display (except if I use the same instance
for all rendering: clicking on one of the first links changes all three
counter displays, as expected).

As with Bills example, there is no need or no data to return. Perhaps 
I am missed something (I *certainly* did...) but I wonder why the
Transcript should print a line of text if I implement the children
