going through the tutorial..

i am working through the ToDo list tutorial, and running into a slight problem..

i am up to the point where i have defined my tasks, users, and
list/menu components..

my menu and list components look like:

WAComponent subclass: #StMenuComponent
        instanceVariableNames: ''
        classVariableNames: ''
        poolDictionaries: ''
        category: 'STTutTodoApp'

and

WAComponent subclass: #StListComponent
        instanceVariableNames: ''
        classVariableNames: ''
        poolDictionaries: ''
        category: 'STTutTodoApp'

when i run the demo so far, initializing StRootComponent, i am getting:

initialize
        super initialize.
        self
  menuComponent: StMenuComponent new;
  listComponent: StListComponent new.

with an error:

StRootComponent(Object)>>doesNotUnderstand: #menuComponent:

any ideas?

thanks!

i found it.. i missed the part where you add the instance variables..
then you add the accessor.. it works now..

while i am on this.. what is the difference between instanceVariable
and instanceVariable: ?

Hi Sergio,
        instanceVariable allows you to get value of desired variable outside  
the class. Similary instanceVariable: is designed to set variable's  
value. This is because of encapsulation, while you have acccess to  
variables only inside the class, where they are defined.
