[Libreoffice-bugs] [Bug 137735] FILESAVE: Objects defects when reopening : loss of backwards compatibility

--- Comment #1 from VLB <vlb1 at vlbnu.nl> ---
When the user saves the file, Calc 4,6,7 save a faulty "register".  On
re-opening the file any or many charts fail to update (not always true and not
always the same charts).

Saving with all Calc versions 5.*.*.* does something more thorough before
writing.  The register is "revised" or "cleaned up" in some way before writing.
 Some charts visible to the user are still frozen yet closing/re-opening the
file finds the new content.xml and object/content.xml compatible, correct and
all charts working.  With further Calc 5 user activity, the first Bug will,
again, cause new freezes of charts.

Saving with format .xlsx causes a similar "revise" or "clean up" as Calc 5 with
an additional final "redraw" of objects that had changes during the user
session.  Therefore, unlike Calc 5, the user sees the presentations jump to the
correct data values.

First and second Bug together.  If the user opens two or three .ods at the same
time and does edits, the "register"  (apparently, it seems) becomes corrupted
across any or many sheets on any of the open files.  Then it's necessary to
File_Save with Calc 5 (then reopen each) or File_Save as .xlsx for all open
files.
