Any idea why the revision number is null? It really should not...

Thanks for all your help and suggestions. I have managed to resolve the issue with ACLs but have uncovered a slightly more troubling problem. The solution was to use denyUser.setNegative( true ) for "/slide/users/john". There was no need to deny the other roles like user.
However, I now find that I cannot delete a file once I have set any permissions on it. For example the code below:
res.putMethod("/slide/files/testFile5.txt","test data"); Ace denyJohn = new Ace( "/slide/users/john" ); denyJohn.addPrivilege( Privilege.READ ); denyJohn.setNegative( true ); Ace[] aces = new Ace[1]; aces[0] = denyJohn; res.aclMethod( "/slide/files/testFile5.txt" , aces ); res.deleteMethod("/slide/files/"+filename); Causes the following exception 14:46:54,162 INFO [STDOUT] java.lang.NullPointerException 14:46:54,162 INFO [STDOUT] at org.apache.slide.store.impl.rdbms.StandardRDB MSAdapter.revokePermission(StandardRDBMSAdapter.java:584) 14:46:54,162 INFO [STDOUT] at org.apache.slide.store.impl.rdbms.AbstractRDB MSStore.revokePermission(AbstractRDBMSStore.java:481) 14:46:54,162 INFO [STDOUT] at org.apache.slide.store.AbstractStore.revokePe rmission(AbstractStore.java:759) 14:46:54,162 INFO [STDOUT] at org.apache.slide.store.ExtendedStore.revokePe rmission(ExtendedStore.java:658) 14:46:54,162 INFO [STDOUT] at org.apache.slide.security.SecurityImpl.revoke Permission(SecurityImpl.java:383) 14:46:54,162 INFO [STDOUT] at org.apache.slide.macro.MacroImpl.deleteObject (MacroImpl.java:814)
Looking at the source for StandardRDBMSAdapter, it appears that the NullPointer is being thrown here: statement.setString(4, revisionNumber.toString());
I would guess this is because revisionNumber is null.
It might be worth pointing out that I can put and delete files where I have not set permissions as described above.
I would value any suggestions as to why this is occuring.
Thanks in advance
Patrick

Sounds very reasonable! Besides me saying that the user may still have access because the role may if is not possible. Confusing...

Hi all, I don't know much about permissions yet, but should'nt the last line be denyUser.setNegative( true ); ?
At least that's what I've undestood from reading the source.
Cheers, Tassos Bassoukos
