Hi Markus,
you mix up the facts. You must be sure that the setting is defined
before using it. The "settings : {}" part defines the default value. It
seems that the theme is loaded before your application. You can change
this by adding a
/*
#require(custom.Application)
*/
to your theme class to force that this class is loaded before the theme
class.
Hope this helps.
Sebastian
