Any idea what’s wrong with this snippet? Looks pretty simple to me.  
Yet no matter what I try, the drop\_receiving\_element helper causes an  
error.

drop here
\<%= drop\_receiving\_element('dropFoo', :hoverclass =\> 'hover') %\>

I also tried \<% drop\_receiving\_element :dropFoo as this seems the  
preferred syntax in Raymond’s AoR. Same problem, though.

Thanks,  
-S.

The error message:  
NoMethodError in Test#draggables2

Showing test/draggables2.html.erb where line #2 raised:

You have a nil object when you didn’t expect it!  
You might have expected an instance of ActiveRecord::Base.  
The error occurred while evaluating nil.[]

Extracted source (around line #2):

1:

drop green here
  
2: \<%= drop\_receiving\_element(‘dropFoo’, :hoverclass =\> ‘hover’) %\>
