Andrew, thanks for the last 'hint'!
It made me realise that I definitely tried to define a class in my
module - see the original code - but did not declare class variables.
So what I did now, was just change the following (see my original code
above):
class << self
mattr_accessor :account_system_type
end
Notice the MATTR_accessor!
That's it! It's working now as if I hoped it would in the first place.
By the way: cattr_accessor works as well naturely.
I appreciate all the comments you made!
