This sounds like you didn't properly setup the chain (as listed below the TT
example).
Verify the following two sections are fully complete (in particular, the
method attributes on "sub object"):
*
http://search.cpan.org/~hkclark/Catalyst-Manual-5.8001/lib/Catalyst/Manual/Tutorial/04_BasicCRUD.pod#Add_a_Common_Method_to_Retrieve_a_Book_for_the_Chain
*
http://search.cpan.org/~hkclark/Catalyst-Manual-5.8001/lib/Catalyst/Manual/Tutorial/04_BasicCRUD.pod#Add_a_Delete_Action_to_the_Controller
PS., the square brackets are to denote "Captures" that are handled by the
Chained dispatch type. In this example, the URL path is
/object/{capture}/delete. If you had arguments after delete, they would not
be in the captures array.
[% c.uri_for( c.controller.action_for('delete'), [ book.id ], 'after' ) %]
would give you a URI like:
/object/1/delete/after
Hope this helps you out.
Thanks,
