Comment #2 on issue 793 by tudor.gi...@gmail.com: TreePresentation does not show the selected item when rendering with Morphic http://code.google.com/p/moose-technology/issues/detail?id=793
Alain fixed the issue. The problem was that in Pharo 1.4, updating MorphTreeMorph has changed
from: self changed: #roots.
to: self changed: #rootNodes.
Thanks, Alain.
