I upgraded my system from Suse 11.0 (KDE3.10) to Suse 11.3 (KDE4.4.4).
In order to use the old Kalender event templates in the new Korganizer I copied them
from #.kde/share/apps/korganizer/templates/event/
to : #.kde4/share/apps/korganizer/templates/event/.

But when I try to use the old template for new Kalender records, I get the message
"Error on loading the template file '/DIRECTORY.../FILENAME'".

I also noticed, the structure of new event template are quite different from the old one. That is surely the error cause.

There is a way or a trick to implement the old templates in Kontact 4.4.5?

Thanks a lot for all kind of suggestions.

Eureka!

After I put the template event names in

#.kde4/share/config/korganizerrc, (line EventTemplates of the section [Internal Settings]),

it goes.
