Remove_observer bug?

fuzzybro

Hi,

I have found following strange behaviour:

I have one EntitiesObserver object and multiple definitions which are bound to the very same EntitiesObserver:


  observer = MyEntitiesObserver.new
  Sketchup;;active_model.definitions.each do |definition|
    definition.entities.add_observer observer
  end

and it works OK.

But when I try to remove observer from the entities I'm able to remove it only from the first definition in the list. Other definition.entities.remove_observer(observer) are giving me the 'false' result and entities are still being observed by this observer.

How do I properly unobserve multiple objects pointing to a single observer?

Is that code in a file that you are loading ?

The local reference observer will be invalid after the file is done loading.

It's a pseudo-code. The actual code implies that observer object is a class instance variable:


class Scene

  attr_accessor(;observer)

  def initialize
    @observer = MyEntitiesObserver.new
  end

  def observe
    Sketchup;;active_model.definitions.each do |definition|
      definition.entities.add_observer @observer
    end
  end

  def unobservre
    Sketchup;;active_model.definitions.each do |definition|
      definition.entities.remove_observer @observer
    end
  end

end
