TypeError: element has no properties / TypeError: Null value in Chapter 5

[Tom Dunning]

Hi,

I've been following the book through and am now at Ch 5, working on
the AJAX add to basket functionality.

It all seems to be fine except for the following error:

RJS error:
TypeError: element has no properties
(in Camino)

or

TypeError: Null value (in Safari)

these appear in dialog boxes, after these are OK'd the cart then
updates.

I've been over the code and cant see what would be triggering this.

Thanks in advance.

Tom.

Hi Tom,

Can you try it in Firefox using Firebug? It would probably give you
more information about where the problem is.

it says the problem is at line 866 of prototype.js, which reads:

this.transport.send(body);


As someone new to ruby i not sure which element is missing properties
(it's being given the book id, what more does it need?!)

*UPDATE*

this same error, and line is appearing when i run the remove command.

The error is from Javascript, not Ruby. Can you update all the
javascripts (there's a rake task for that in Rails) and see whether
the error will go away?

I've run "rake rails:update:javascripts" and it ran, but the error
still remains.
Ideas?
