inputChanged

public void inputChanged(org.eclipse.jface.viewers.Viewer viewer,
                         java.lang.Object oldInput,
                         java.lang.Object newInput)

Following the pattern of removing listener from old input and adding to new input. Net result is there is always a listener, which is correct. The input never changes in this example, but the pattern is followed just in case things do 'change' later.
