Rails spinoffs - Sep 2005 - Ajax in the Aguile Web Development... book

I have bought the book, and are working with chapter 18 (about Ajax).

I don''t get the List application example to function as expected. When
i fill inn a name, and presses "Add Item". The button gets gray, the
text "Adding..." is coming up, and the item is being written in the
top of the page, but then it freezes here.

I uses the newest rails, installed with Gem, and  WEBrick 1.3.1
server.

When i push the action I get the following output from WEBrick:

127.0.0.1 - - [25/Sep/2005:20:28:33 CEST] "POST /list/add_item
HTTP/1.1" 200 247
- -> /list/add_item

Anybody knows if this is a bug in the code in the book, or have any
suggestions on solutions?

The code can be downloaded from:
http://pragmaticprogrammer.com/titles/rails/code.html

I''ve tried both Firefox, Opera and Galeon for linux (Ubuntu), but get
the same result with all of them.

Regards
Henrik

It seems that the Effect.highlight call is bombing in that script:

Error: this.element.style has no properties
Source File: http://0.0.0.0:3000/javascripts/effects.js
Line: 236

The line is:
var current = this.element.style.backgroundColor;

If you take the highlight call away, everything seems to work normal  
(except there''s no highlighting, of course).
