Rails - Nov 2005 - Help required with in_place_editor_field and in_place_edit_for

Hi,

I have a PagesController which renders a partial collection of  
Sections, each of which renders a partial collection of Lists, each  
of which renders a partial collection of Items.  All on the same  
page, and it all works fine.

I''m attempting to turn the display of Item.name and Item.description  
into edit-in-place fields, with no joy so far.

First question, I have this at the top of my controller:

class PagesController < ApplicationController
   #...
   in_place_edit_for :item, :name
   in_place_edit_for :item, :description

If I understand the framework code correctly, those two lines should  
result in two new methods being declared, called set_item_name and  
set_item_description.  But when I insert a breakpoint() call just  
after those lines, and look at the output of "methods", they are not  
listed.  respond_to?("set_item_name") returns false as well.  What am
I not understanding here?

Second question:

When I include the following in my _item.rhtml:
<%= in_place_editor_field ''item'', ''name''
%>

I get this error in my browser:
   Called id for nil, which would mistakenly be 4 -- if you really  
wanted the id of nil, use object_id
which happens in:
/vendor/rails/actionpack/lib/action_view/helpers/ 
java_script_macros_helper.rb:62:in `in_place_editor_field''

I''ve tried all combinations of :item, ''item'',
''name'' and :name in my
view to no avail (as I expected).
<%= item.name %> in the same partial works fine, so Rails can access  
the "item" object and find out its name when it wants to.

I''ve tried this with 0.14.3 and edge rails, with the same result each  
time.  Am I doing something wrong, or is this broken in the latest  
release?

Jon
