Re: [Modeling-users] Notification Framework v0.5 released

[Thorsten K. <tk...@co...>]

Hello,

first of all I would like to thank Sebastien for his work on the nice 
frameworks.

I've tested the new feature and it is possible now to add an observer 
with different methods for different Notifications.
But it should be pointed out that one has to define a value for the
key 'NOTIFICATION_CENTER_MULTIPLE_CALLBACKS_PER_OBSERVER' in the 
environment, in order to enable the new behaviour.

Sebastien, thanks again for the fast response to the feature request,

Have a nice day,
yours kodi
