Observer problem onDeleteModel ?

[derei]

**I tried this, according with Ruby Api:

class MyModelObserver < Sketchup;;ModelObserver
	def onDeleteModel(model)
		UI.messagebox("onDeleteModel; " + model.to_s)
	end
end
Sketchup.active_model.add_observer(MyModelObserver.new)

but I had the unpleasant surprise to see that nothing happens when deleting something.
Should I use entity observer? I will give it a try, but I suspect that is my answer. Anyway, this post stays because I want to understand what "model" means.
When this observer reacts?**

I would guess the onDeleteModel method only fires on a Mac which can have multiple models open simultaneously.

An EntitiesObserver might be appropriate:

I tend to agree that your guess is right ! If it's confirmed, maybe it would be appropriate that this mention to be added in SU Ruby Api (Google guys do this? )
