Sorry for late reply.
I have solved the problem. But I want to add to your post some points.

You can use InteractiveDisplayElement or OSMF class LayoutTargetSprite.
container.addMediaElement(InteractiveDisplayElement)
or
container.layoutRenderer.addTarget(LayoutTargetSprite)
To snap to DisplayObject of DisplayObjectTrait of MediaElement you should use InteractiveDisplayElement and change it’s size in accordance with DisplayObject (DisplayObjectTrait dispatches DisplayObjectEvent.MEDIA_SIZE_CHANGE).

To lay your InteractiveDisplayElement over other MediaElement use property index of LayoutMetadata (MediaElement’s LayoutMetadata.index = 0 and InteractiveDisplayElement’s LayoutMetadata.index = 1).
Hope this will help someone.

Thanks for reply Tiago.
Unfortunatly no.
My main question is: why UIComponent is not displayed when it is wrapped with InteractiveDisplayElement while Sprite is displayed.

Does UIComponent too complicated?

Also I have a very strange problem with positioning of InteractiveDisplayElement:
If I use ImageElement to test, everything is OK. But replacing ImageElement with InteractiveDisplayElement(Sprite) causes changing of Sprite’s size and position.

I definetly stuck.

@Denis: I think the reply to your comments is either simple or very complicated, I assume heavily that if you don’t use my InteractiveDisplayObjectTrait, the element will be positioned with it’s default settings, when calling it’s setSize function the element will be replaced based on the final completed layout, basically a refresh of the controllers and layout.

updateSprite only needs to be set once, and the element is either being called once and if there is a need to change the element you simply destroy it and set it up again.

Does it make sense?

In addition. I’m using almost identical approach as your’s. Just without InteractiveDisplayObjectTrait but with original DisplayObjectTrait.

In InteractiveDisplayElement’s constructor I call
super();
addTrait( MediaTraitType.DISPLAY_OBJECT, new DisplayObjectTrait(sp, mediaWidth, mediaHeight) );

Why do you need an addition Sprite object in InteractiveDisplayElement.updateSprite? This function works correct only at first call. At second it only changes size.

I have the same problem: my Sprite object is displayed, but it’s positioning is very strange.
If I use UIComponent it is not displayed at all.

Tiago, describe please why it’s so strange and how to lay Sprite or UIComponent over MediaElement with a DisplayObjectTrait.

Because the mx.controls.Label has a base class of UIComponent and not Sprite. Change the Class extension to it and it should work fine, let me know the result.

But…

If I create a mx.controls.Label with a text and pass it to the InteractiveDisplayElement nothing is presented. It works with TextField but not with any Flex Component. Why?

We know tons of work went into the framework. Time to celebrate and start creating some awesome media players!
