Writer: canceling dispose event

Hi,

I have a listener on a Writer document, which gets
triggered, when the
document gets closed by the user. The file should then be
transferred to a
database, but it is still locked by OpenOffice. When I try
to manually
dispose Writer in the event, OpenOffice crashes, which is
not a surprise
considering that it is already disposing. Can I cancel the
disposing or
release the file in another way?

Does anyone has an idea?? Thanks in advance!

Regards,

Michael
