bug with collisions shapes in saved scenes

[curly-brace]

• create saved scene with staticbody2d as root
• add it to game scene
• add collisionshape to it
• rigidbody2d will fall through it

it will only work if collisionshape not only added inside savedscene, but also configured (shape created) in its hyerarchy and not in game scene hyerarchy.

and if you move such (with enabled editable children) collisionshape (part of saved scene) somewhere down (for example putting it after an added sprite node (inside game scene i mean)), there would appear two collisionshapes, one read and one white, but you couldn't delete ant of them anymore.

i was trying to create a general staticbody2d with script, that would represent different types of platforms, depending on settings i setup in exported script options. the only things i planned to edit manually - adding sprite nodes and collisionshape (one) as children of that instanced saved scene, but now it is impossible to implement.

godot 2.2 latest.

Workaround from @bojidar-bg there:

func _ready():
    for shape in get_children():
        if shape.has_meta("__registered") and shape.get_meta("__registered"):
            continue

        get_tree().set_editor_hint(true)

        remove_child(shape) # Make it pick up the editor hint
        add_child(shape)

        get_tree().set_editor_hint(false) # Unset quickly

        if shape extends CollisionShape2D: # Now update parent is working, so just change the shape
            shape.set_shape(shape.get_shape())
        elif shape extends CollisionPolygon2D:
            shape.set_polygon(shape.get_polygon())

        remove_child(shape) # Reset its editor hint cache, just in case it was needed.. (you might drop this part if it bottlenecks)
        add_child(shape)

        shape.set_meta("__registered", true)
