My plugin has two models made in EMF, a datamodel and a view model.
There's a 1-to-1 mapping between
my view model and my editparts. My editparts represents a tree with nodes
and links. I need to be able
to "collapse and expand" my tree. If i click on a node I want the child
nodes and child nodes of child nodes and so on to disapear. If i click on
a collapsed node i want the child nodes to show again. How do I do this
the "clean way"?
Should I remove the visuals for the editparts that I dont want to show, or
remove the model object from the view
model?
Lars.

I like making figures invisible too. I had severe problems for
instance, trying to add a label figure and remove it based on a property
of the model. This was because of my funky layout manager I am guessing.
So I dont relayout them. I add figure, and setVisible depending on what
the model wants.
If its only appearance, I wouldnt remove the models. Tree does not
'remove' its nodes from the model when they are hidden.
