ok..Run the first time....Stop ... Apply ...Clear/Update (for input a new the selection)... make the trick..
even direct selection don't work for me...

But for go out the node for use the result i must use this (not a big deal)... is that the same for you ?

script:/*go out nodes*/ var objs = moi.geometryDatabase.getObjects(); for ( var i = 0; i < objs.length; ++i ) { var obj = objs.item(i); obj.setHitTest( true );
