connectPresenters 
������ scripts whenSelectedItemChanged: [ :class | 
������ ������ source clearContent; behavior: nil.
������ ������ class ifNotNil: [ 
�� �� ������ ������ methods resetAllPageContents.
�� �� ������ ������ (methods pageAt: 1) whenRetrievedDo: [ :list�� |�� list�� items:�� class methods].
������ ������ ������ (methods pageAt: 2) whenRetrievedDo: [ :list�� | list�� items:�� class class methods].
������ ������ ������ methods resetAllPageContents.]].
