Description Erwin Betschart

Build Identifier: 3.0

CDO should provide an option to lock outgoing reference targets during commit. 
This would prevent a case of stale references.
E.g.: 
Object A references object B. When changing and committing the object A also object B should be locked so that no one can remove object B.

Reproducible: Always

Doesn't this duplicate bug 315407 ?

The new reference target locking can be switched on with a new *boolean* repository property:

   IStoreAccessor.CommitContext.PROP_AUTO_LOCK_NEW_TARGETS = "autoLockNewTargets"
   
It is off by default!
