[typo] Amazon Sidebar Component Broken?

This is the line of code that's confusing me:

asin_list = params[:contents].to_a.inject([]) { |acc, item| acc |
item.whiteboard[:asins].to_a }

When I set a breakpoint after this line, asin_list always contains nothing.

params[:contents] contains a ton of stuff including the html contents of my

asin_list = params[:contents].to_a.inject([]) { |acc, item| acc}
returns nothing

asin_list = params[:contents].to_a.inject([]) { |acc, item| item }
returns pretty much the same thing as params[:contents]

Toward the end of the string returned by the last asin_list above, there's
this: "whiteboard" =>{}
So, it looks to me that something should be setting something into this
whiteboard, maybe.

If I look at:
asin_list = params[:contents].to_a.inject([]) { |acc, item| item.whiteboard}
I get {}

asin_list = params[:contents].to_a.inject([]) { |acc, item|
item.whiteboard.to_a }
returns []

So, what's the whiteboard, and how does stuff get into it?


asin_list = params[:contents].to_a.inject([]) { |acc, item|
