You're probably right here.

As far as I know (I don't know much, by the way) you can either:
- DataEditorSupport.create (default behaviour) [1]
- Create your own EditorSupport. [2]
- Create an object that implements OpenCookie and CloseCookie and use
that to open/close your own TopComponent. [3]

... and then add that to the getCookieSet() in the constructor of your
custom DataObject.

There's another thread about singletons, but I don't think you really
want a singleton TopComponent for editing your file. You may want
different instances of your TopComponent (as different tabs of your editor).
