I have another problem with the following example

WASimpleNavigation class>>example

^ self new add: WACounter new label: 'yet another counter'; add: WAPath example label: 'a cool path'; yourself

When I press the ++ or -- of the counter I get an error Error: Components not found while processing callbacks: #(a WACounter)

So I tried to add

WASimpleNavigation>>children ^ Array with: self objects

WASimpleNavigation>>objects ^ components collect: [:ea | ea value]

but it did not fix the bug and I do not know what to do. What is my mistake?

Thanks
