But why do you put a trace at that point? Of course a is a hash there,  
but you are not aggregating the hash, you're collecting the  
*collection of values of those hashes* via a.values. You need to work  
with tha variable "values" which is assigned the result of the  
map.chain. Please inspect the array stored in the variable "values"  
after that block of code has run.
