As contentstore I'm using slidestore.reference.FileContentStore 
with enabled versioning. Btw: Is it necessary to enable 
versioning there? I guess not, because of DeltaV.

For the other stores I'm using 
slidestore.reference.JDBCDescriptorsStore with HSQLDB.

What I did with Slide 1.0.16 client (scope set to /files), Slide 
2 on the server:

[LOCALHOST] /dms/kurs2/ $ propput /dms/kurs2/t1.txt 
getcontentlanguage de
Putting property(getcontentlanguage, de) to '/dms/kurs2/t1.txt': 
succeeded.

Slide log:

29 Oct 2002 11:11:17 -

Then I tried it as user root on a new file:

*1st try: the same like above, DAV:checked-in property set to 
new version 1.1, but no new version under associated VHR.

*2nd try: like 1st try

*3rd try: now it gets interesting, revision not found:

[LOCALHOST] /dms/kurs2/ $ propput /dms/kurs2/t2.txt 
getcontentlanguage de
Putting property(getcontentlanguage, de) to '/dms/kurs2/t2.txt':

*2nd try: now Slide client says succeeded again, but rollback in

I stop here.

This looks like a problem with rolling back transactions.

Thanks.
