[Seaside] Another question before going to sleep :)

[stephane ducasse]

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
