[Digikam-users] How to use versioning?

[Andreas Mair]

Hello,

I've finally found time to update to KDE 4.8.5 and digiKam 2.8.0 and
test again. But nothing changed.

For your convenience I copy'n'pasted my findings from a previous mail:
digiKam settings: Metadata / Behavior / Reading and Writing Metadata
If I enable "Write to sidecar files" and set this option to anything
but "Write to XMP sidecar for read-only image only" versioning
*doesn't* work (even if image is read-only).
I mean:
- on that page I've only enabled "Read from sidecar files" and nothing
else => versioning works (history OK)
- now enable "Wright to sidecar files" and set it to "Write to XMP
sidecar for read-only image only" => versioning still works
- now set "Wright to sidecar files" to "Write to sidecar only" or
"Write to image and XMP Sidecar" => versioning *not* works

By talking about "versioning" I mean that I open an image in the
digikam editor, apply some filter and then call "save changes".

Any ideas what's sill wrong? I've appended the used components at the
end of this mail.

Best regards,
Andreas
