Before deactivating a linked OLE saved it and overwrote the original, even when not saving the hosting document at all. This is not intuitive from user perspective and may lead to unexpected data loss (of the OLE content). Reported case was especially about closing the hosted document without saving in the understandable believe that that way the changed OLE will not be changed on external medium. Added mechanism for linked OLE to hold data in a hidden local temp file, synching/writing back on hosting file save. Most complicated was adapting the 'break link' case and ensuring other cases to work, but looks good now from my POV Change-Id: I7f63d667820b2d9725abc598a9dd7360be1f8d5a Reviewed-on: https://gerrit.libreoffice.org/c/core/+/113793 Tested-by: Armin Le Grand <Armin.Le.Grand@me.com> Reviewed-by: Armin Le Grand <Armin.Le.Grand@me.com>
