Yes it does. You've just forgot to signal a refresh (view raw signalUpdate).

Try this:
-=-=-=-=-=-=-=-=-=

view := ROMondrianViewBuilder new.
       view shape rectangle size: 20.
       view interaction on: ROMouseEnter do: [ :event |
                               view shape line color: Color blue.
                               view edgesFrom: [ :i | i \\ 2 ].

                               view raw signalUpdate

                       ].
       view nodes: (1 to: 20).
       view shape line.
       view treeLayout.
       view open
