Hello,
I run application on second screen (or I move it to second screen), then I want to open second window

MWindow window = modelSrv.createModelElement( MWindow.class );
window.getPersistedState().put( "efx.window.stagemodality", Modality.APPLICATION_MODAL.toString() );
MPart part = partSrv.createPart( TEST54_APP_PARTDESCRIPTOR_0 );
window.getChildren().add( part );
window.setWidth( 200 );
window.setHeight( 200 );
app.getChildren().add( window );

Unfortunetally second window will be appear on primary window - but parent window is on second screen.
Whether it is intentional? Or should be appear on screen, where parent window is?

You are adding the window to the application, so you get a secondary top
level window who has no parent window! If the new window should be a
child of the first you need to add it to the parents windows child list.

In general you are responsible for the location of the window by default
it will be opened at 0/0 so if you want to at a different location you
need to set the x/y coordinates appropriately!

I uderstand, but parent is still null:

app.getChildren().get( 0 ).getWindows().add( window );
System.out.println( window.getParent() ); -- null; why?

Because getParent() is bound to the MElementContainer hierarchy! The
only way to access the parent window would be through EMF-API
(eContainer) which is internal.

I think you should file against the Eclipse Platform to provide API to
access the parent window.
