I am reasonably certain I am doing everything exactly as instructed.

Following the workbook line by line, by the time I reach page 5 and run the app:

HTTP Status 500 -

type Exception report

message

This is surprising, typically the Force.com workbooks are flawless and following the examples works as expected.

Anyone else notice this, or is this user error?
