Prevent Child Selection with policy? [message #97509]

I have a component that contains other parts. I prevent its children from
being selected if I drag a box around this compomnent, or a box that just
contains its children by returning false to isSelectable if this
components parents parent is not a RootEditPart.

Is this the architecturally correct way to do this? Is their a selection
policy or anything for the container? Anyway I can use a policy for this?

Is this related to "grouping" above?

Well it wasn't. This was my first method. where you basically have a
component and when you duble click it, you can edit its contents. But I
have changed to a more dynamic method of giving the user a blank slate and
letting them make the component from scratch. Then group it as a form of
'making' the component. Then double clicking will open a window that will
temporarily explode the component for editing.

So the grouping technique is a replacement of this one. But I learned a
lot about the arch with this one.
