question regarding shorthand syntax for collection rendering

Hi all,

I have a collection which I render via

<%= render :partial => 'comment', :collection => @results %>

This works exactly as I expect it to.

However, when I change it to

<%= render :partial => @results %>

or

<%= render @results %>

both of which the documentation describe as 'short hand' versions of
the first, I get:

Missing template _comment.erb in view path

in spite of the fact that the template is there and renders correctly
in the first case.

I'm using 2.3.8. Anybody know what is going on?

Thanks for any help.

Never mind. It appears active scaffold is actually messing this up. In
a newly created project without active scaffold it works just fine.
