If i run this task from command line, i get this error:

ERROR [User Warning]: None of these templates can be found in theme 'jotoedi': Anmeldungen.ss IN GET /AnmeldungenTask

Problem Solved!

The Problem is caused by the different manifest files CLI and WEB use!
So you have to run this:

php /path/project/sapphire/cli-script.php AnmeldungenTask flush=1

to generate the new manifest files for the cli script!
