Thanks for pointing that out Ryan, I'm sorry I should have been more
clear. I know why the error is occurring in the page (I can see
currently there is the opportunity for it not to be set, and will
revise that once I've finished sorting out the fact that it's not
being sent by 'redirect'), it's the cause of the variable being MIA
when redirect should be sending it that I need to fix first.
The bug you've pointed out is (right now), kinda helpful in that it
lets me know that categoryID is missing when it should be populated by
redirect.
I still have no idea why I'm not getting any parameters from redirect
in my edit method:
$this->redirect(array(
'controller' => 'subcategories',
'action' => 'index',
$categoryID
));
