Inheriting yaml attributes

Content-Type: text/plain;
charset=ISO-8859-1;
format=flowed

Sorry for the stupid question but why doesn't this work:

def to_yaml_properties
return (super.to_yaml_properties + %w{ @url })
end

I am in a subclass of a class where I have:

def to_yaml_properties
%w{ @abbr @descr }
end

Obviously, I want the result to be an array with @abbr, @descr, @url

But when I print the result:

ping.to_yaml_properties.each { |prop| puts "-- " + prop.to_s}

I get only @url

Something obvious must be wrong here!?!

"super" calls the overridden method in the superclass. This is different
from Java, for example.
