            Bug ID: 141530
           Summary: Linked OLE: When same linked OLE is hosted by two LO
                    instances change is indeterministic
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: Armin.Le.Grand at me.com

While fixing aspect (2) of tdf#130945 I stumbled upon the following error:

A prepared OLE might be opened by two running instances of LO at the same time.
In this scenario (besides also (2) creates irritation here) it is
non-deterministic who's change gets applied. This depends on which instance of
LO deactivates the shared OLE first (or with (2) fixed, who saves the hosting
document first).
A fix of this would need to evtl. check when inserting the shared linked OLE if
it is opened already by another instance, or - alternatively - check on
save/deactivate and evtl. ask user if he wants to discard or copy the OLE -
something like that, details need discussion.

Also refer to aspect (3)
