simple table column bindings

hi,

I'm having some trouble with completing a simple proof of concept app. 
The requirement is to process a simple xml document and display the 
results in a two column table.

I've managed to load the xml and parse what I need from it into a 
bunch of "Movement" objects which I attempt to add to a 
NSArrayController. My table actually displays three records but only 
with the null placeholder. Some where along the lines the bindings 
I've specified for the two table columns are broken.

If any of you have 5 minutes a copy of my project is available at:

(You'll have to forgive the "Foo" class, it seemed like a good name 
for the class a couple of days ago)

The app it's self is pretty simple, clicking the "load" button should 
populate the table with the data using the example.xml resource.

Any help would be gratefully received.

Thanks in advance
Gareth Davis
