My Entities Observer seems to be conflicting with the push pull tool

Hello everyone, my EntitiesObserver has the ability to detect added faces, create groups, and add various objects. Below is the code content of my EntitiesObserver.

module Test
  module TestFunc       
    
    class TestObserver < Sketchup::EntitiesObserver
      def onElementAdded(entities, entity)
        return unless entity.is_a?(Sketchup::Face)
        if entity.normal.z == 1 then
          gp = entities.add_group()
          gp.entities.add_line([5, 0, 0], [5, 0, 0].offset(Z_AXIS, 1000))      
        end
      end
    end

    class TestGroup
      mod = Sketchup.active_model
      ents = mod.active_entities
      points = [[10, 10, 0], [20, 10, 0], [20, 20, 0], [10, 20, 0]]        
      gp = ents.add_group(ents.add_face(points))
      observer = TestObserver.new()
      gp.entities.add_observer(observer)      
    end
    
  end
end

However, if you enter dimensions using the Pushpull tool on the face of the group to which my EntitiesObserver is applied, the pushpull will not be as much as the dimension, but only up to the current mouse cursor. Also, it seems like the pushpull function doesn’t end and the pushpull continues to run as the mouse moves. Is there any way to solve this problem?

Read the note at the top of: Class: Sketchup::EntityObserver — SketchUp Ruby API Documentation

You may have programmed a “vicious circle” by creating entities within an observer callback that fires when entities are created.

At the very least delay the group creation inside the callback using a UI.start_timer block.

Thank you for your reply. I guess I’ll have to find another way.
