UNCONFIRMED  errors and comments from readers: 


[10]  2nd paragraph;
The suggested method for specifying what template I want to render gives me the
following error.

'No rhtml, rxml, rjs or delegate template found for account/product.rjs'

I'm pretty sure the file is there.


{25}  2nd Code block;
The javascript created by:
  page.insert_html :bottom, 'expenses', :partial => 'expense'

...raises an error under IE on XP using rails 1.1.  The issue seems to be the attempt
to insert the HTML into a table - if I change the original item to be a DIV then all
is well.

I am unsure of a suitable fix for this problem...  Everything works fine in Firefox
though

(25)  2nd paragraph;
Last sentence:

Create app/views/new.rjs and add the following code to it:

I think "new.rjs" file should be created in "app/views/expenses/new.rjs"



(31)  2nd paragraph;
views/expenses/_form.rhtml should be views/expenses/_new.rhtml 


  
 
{34}  Code block before the last paragraph;

<% form_remote_for :expense,
                   Expense.new,
                   :url => hash_for_expenses_url(:project => @project, :action =>
'new'),
                   :loading => 'Form.enable("expense-form")',
                   :complete => 'Form.disable("expense-form")',
                   :html => { :id => 'expense-form' } do |f| %>


should be:

<% form_remote_for :expense,
                   Expense.new,
                   :url => hash_for_expenses_url(:project => @project, :action =>
'new'),
                   :loading => 'Form.disable("expense-form")',
                   :complete => 'Form.enable("expense-form")',
                   :html => { :id => 'expense-form' } do |f| %>
		   
		   
[35]  Last Example;
The code reads:

  page.alert "The Expense could not be added for the following reasons:\n" +
@expense.errors.full_messages.join("\n")

This doesn't work for me on Firefox as (from what I can see) the errors string has
it's quote marks escaped and you end up with something like

"The expense error blah blah ..." + "Some Error text

I got around this by doing

  page.alert("Msg ...: #{@expense.errors.full_messages.join("\n")}")		
		   
		   
		      
{38}  Second Code example;
"page.replace 'summary', :partial => 'projects/summary',..."  should probably read
"page.replace 'summary', :partial => 'expenses/summary',..."


{38}  new.rjs code block in the middle of the page;
The highlight effect line:
  page.visual_effect :highlight, 'expense-#{@expense.id}'

needs to be:
  page.visual_effect :highlight, "expense-#{@expense.id}"

With the single quotes, it doesn't perform the id substitution		   


(38)  4;
Original reads:
  page.alert "The Expense could not be added for the following reasons:\n"
        + @expense.errors.full_messages.join("\n")

This caused errors for me on rails 1.1 (windows).  I have to change it to:
  page.alert "The Expense could not be added for the following reasons:\n" +
              @expense.errors.full_messages.join("\n")

In fact simply moving the "+" sign off the top line seems to cause an erro
