```java.lang.ClassCastException: tornadofx.Scope cannot be cast to knote.tornadofx.model.NotebookScope
	at knote.tornadofx.view.NotebookSpace.&lt;init&gt;```

How is NotebookScope defined?
If it is `NotebookScope: Scope` then you're trying to cast parent to child, which can't work, as child is more specific and there are no garantees that parent will satisfy child spec. With casting you can only lower specificity, casting from child to parent, not the other way around.

So you might want to call on you version of the scope `super.scope as NotebookScope` to `super.notebookScope as NotebookScope` ?

ahhhhh you know what - I may have notebook scope defined wrong

thanks for the call out guys, I appreciate it
