It looks like there is a problem passing an array of hash to a partial  
render via a collection.

I am trying to do the following:

\<%= render :partial =\> “listshop”, :collection =\> @pca %\>

and @pca has the following:

@pca = Array.new  
@pca \<\< Hash[“test” =\> “1”]  
@pca \<\< Hash[“test” =\> “2”]

and in \_listshop.erb, I have the following:  
\<%= listshop[“test”] %\>

I get an “You have a nil object when you didn’t expect it!” error. If  
I pass a value instead of a hash it works fine and if I manually  
iterate through the array it works fine as well.

Anybody knows why? Am I doing something wrong?

My bad,

\<%= listshop[“test”] %\> should be \<%= test %\>
