The variable is being destroyed when you redirect. I would change the action to
one that finds the data (in your example this is process). Check for
$this->data. If it's empty there are no search criteria so redirect to your
search page. If it's not empty, do your find and put the results into a
variable ($results?). Then have a view called process.ctp (at this point,
having a function and view called process sounds wrong - 'results' sounds more
intuitive?). In the view, you can pick up your $results and display them.
