[Facebooker-talk] view problem

[kevin lochner]

here's the where the breakdown happens, from model.rb.  You can see  
that location gets
set to "" if it's not a hash.

       def hash_settable_writer(symbol, klass)
         define_method("#{symbol}=") do |value|
           instance_variable_set("@#{symbol}", value.kind_of?(Hash) ?  
klass.from_hash(value) : value)
         end
       end
