Comment #3 on issue 790 by alexandr...(a)gmail.com: adding Mondrian subview
interactively operates on wrong node
http://code.google.com/p/moose-technology/issues/detail?id=790
Most of the mechanisms to update nodes in Mondrian are a kind of hack. As
soon as you have two or more nodes with the same model, then the
interaction will simply not work.
Regarding your suggestion for for the class MOAnnouncer, it does not have
the same effect. It turns some tests yellow.
I turn this issue WontFix because it simply cannot be fixed.
Roassal provides a simpler model for building interactive visualization,
especially with node update.
