Deletion of document via XPage doesn’t cause deletion of DAOS enabled attachments

Need your help in the following issue:

I have DAOS enabled XPage application (NSF database). All attachments go to DAOS NLOs when uploaded via XPage. When deleting documents via View (in Notes) – documents are being deleted with its NLO-attachments as expected.

Issue with deleting documents via XPage: doing it like

dataSource.getDocument().removePermanently(true)

deletes document but doesn’t delete NLO-attachments from DAOS.

The App database still contains DAOS tickets. Only helps command “load compact -c appDBname.nsf”. Compact causes DBPrune, which cleans that lost (not referenced) NLOs.

Additional information:

It is Domino 9.0 Server.
DAOS param “Defer object deletion for” set to “0”.
Nightly Daos Prunes also doesn’t clean NLOs (log content: DAOSMGR: DbDelete started -> DAOSMGR: Prune 0 started -> DAOSMGR: DbDelete completed -> DAOS Prune - Deleted 0 objects and completed with error: (0) No error -> DAOSMGR: Prune 0 completed).
APP DB has “Synchronized” state.
It’s clean test environment with only one single app, so it is definitely that there are no other applications, which refer to the same NLOs.

Any ideas & advices? Thanks in advance!

Solution

So, I can close the issue with the following workaround. As I wrote before, to not have such issue - deletion should be performed by user with at least Editor access level.

So, as workaround: use SSJS and get document via SessionAsSigner.

I didn't find yet explanation in documentation why it depends on access level...
