OfficeDocument is not a valid type here. You have to use any interface
from our documents - I would recommend to use com.sun.star.XModel.

I assumed that if you wanted to use the reference to the document as an
identifier for it you will need to store it somewhere in a list, a table
or whatsoever. In this case you must remove it from this list again when
it gets disposed. For this purpose a listener comes in handy.
