error: MessageNotUnderstood: StRootComponent>>menuComponent:

[Chris Dawson]

Hi there,

I'm running the one-click installer for Seaside 2.8.1 and am running into some trouble following the tutorial (http://www.swa.hpi.uni-potsdam.de/seaside/tutorial) and would appreciate help.  I get this error message:

"MessageNotUnderstood: StRootComponent>>menuComponent:"

This looks to me like the instance variable menuComponent is not defined, but I see it when I select the StRootComponent in the object browser. 

Enclosed is a fileOut.

Chris

Look closely: The message 'menuComponent:' is not understood by objects
of the class 'StRootComponent'. This means that the definition of the
setter method is missing, not the definition of the instance variable.

Try defining the message by something like

        menuComponent: aComponent
                menuComponent := aComponent

or whatever makes sense in the tutorial's context.

It looks like accessor methods are missing. If you click on
StRootComponent -> refactor class -> accessor you can automatically
create the required accessor methods, and then your application works
too ...
