You can use a filter. The type mapper is there for that.
You should consult the description of the extension point
org.eclipse.ui.views.properties.tabbed.propertySections on this point.

Indeed, it sounds like the setInput method is called after the
I think that was made deliberately by Anthony Hunter.
You can workaround that by using a StackLayout, and switching the top
element depending of what is set.
The real workaround is to have different sections registered for each
type of element registered.

You can set a listener on the editor.
You can also listen to the EMF resource, not sure what you'd rather use,
I'd say both.
