UNLOCK with 'abort' transaction status don't abort the transaction

Hi,

I have the following sequence of webdav command calls:

This sequence resulted in creation of 'WA' node though UNLOCK command
contained "abort" transaction status.
Why the transaction was not aborted?
What should I do to be able to rollback transaction?

The same situation happens if UNLOCK command is not called (no commit
takes place).

I can't contribute to the question, but it reminds me that we really 
need to review how the Jackrabbit WebDAV stack is marshalling 
transactions. I know that it's borrowed from Exchange and Slide, but 
that doesn't mean it's the right thing to do...

Best regards, Julian

hi

please note, that the 'local' scope only informs the
server, that any subsequent modification flaged with the
locktoken return by this special LOCK request must
be treated as transient modification. Session.save() or
Item.save() will be called upon the UNLOCK only.

see the corresponding docu draft at

http://www.day.com/jsr170/server/JCR_Webdav_Protocol.zip

real transaction is not supported anyway at the moment,
since it has been decided once, that dependency to
jackrabbit-core should be present in the jcr-server. the
corresponding code therefore was commented.

regards
angela
