I've been trying to keep Dialogue working (as we use it here). I have encountered a problem with backing up. The problem is certainly in 1.6, I haven't tried it in 1.5.
The first backup page is presented with the options to pick the activities to backup and the inclusion of user data. Dialogues are correctly shown on this page.
The next page is the Backup Details. At this point Dialogues are not shown although there are no errors. If you continue to the next page where the backup is performed a notice is shown:
Notice: Undefined index: dialogue in /srv/www/htdocs/moodle/stable16/backup/backuplib.php on line 976
I guess the Dialogue backup has slipped behind some changes in backup/restore that I am not aware of. As I have never dealt with backup/restore module coding before, any pointers would be appreciated.
