hello,
a few days ago I discovered a bug in the "generate UUID" option when
importing metadata into GeoNetwork.
When you use this option, it supposedly generates a new UUID for the
inserted metadata, leaving any existing metadata that might have the UUID in
the imported metadata intact.
However in reality it deletes the existing metadata (if it exists) that has
the same UUID, before inserting the new metadata without generating a UUID.
The bug has been fixed immediately by Mathieu Coudert (thanks !!) and can be
found in the 2.4 and trunk branches, so if you build yourself you can
quickly apply the fix. As no bugfix release has been issued for this, I
thought it better to post this warning because it can cause you to lose data
with no warning.
Kind regards
Heikki Doeleman
