[Seaside] seaside tutorial part 1

[Rob Whitfield]

I'm having trouble with the first tutorial.  I'm running with comanche.  I 
followed the steps up to just before "Getting Fancier: Bindings".  When I 
browse to the page I get the little form just fine.  But when I enter a 
value, select a currency and click the "Convert" button I get the shown 
dump.  I'm somewhat new to squeak and comanche and seaside so maybe I'm 
missing something obvious.  Can anyone help?  Sorry for the formatting of 
the dump - if you want you can view a formatted version of the dump at 
http://www.customfun.com/seasidedump.html
