1001 question about dynamic adding hotspotm (solved)

Can't understand one simple thing:

Wnen i dynamicly creating hotspot via addhotspot() function https://krpano.com/docu/actions/#addhotspot let's to say in one scene, hotspot places outside the <scene> </scene> tag.

If i get xml.scene of the current scene, there is now hotspot, that i added

But... in vrtoureditor.swf when i make hotspot to connect scenes, it places right in the current scene. And the question is - HOW???

Finaly i did it! The only way to add xml of the added hot spot is setting scene.content
Step one - get scene.content
Step two - forming string of the hotspot
step three - combine scene.content and forming hotspot string
step four - set new scene.content
