Matt,
The JSTL expression language has changed. You should now write
${param.action == 'Edit'}
Actually, 'request:action' would have never indicated a request
parameter; it would have indicated a request-scoped variable
("attribute"). Now, you'd use ${request.action} to indicate the 'action'
variable in 'request' scope.
