<span class="corners-top"></span>I have problems in understanding
this code. It is from the WAExampleBrowser. I added an additional
instance variable b to this class and changed the following
methods.<br>
<br>

super initialize.<br>
self class: self allClasses first.<br>
b := 5.</code><br>
<br>

The question is: What is the value of instance variable "b" of
the receiver at the location of "self halt".<br>
<br>
The answer is: 5 - but why !? what state of the instance do I
see in the callback ?<br>
<br>
</code>I know that the Seaside book tells one: "Your rendering
method is just for painting the current state of your component,
it shouldn't be concerned with changing that state". <br>
