It works perfectly when you use:

    \documentclass[man,12pt,hyper]{apa}

Note that extra 'hyper' option.

Looking through  apacite.sty  you'll find coding:


%%%%%% Hyperref compatibility option %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
% (This does not work completely satisfactory, so
% is only a non-default option.)
%
\newif\if at hyper@APA at comp
  \DeclareOption{hyper}{%
  \@hyper at APA@comptrue % hyperref compatibility option is on
}
%%%%%% End Hyperref compatibility option %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%



and further down, the coding that does the work:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%                   COMPATIBILITY WITH HYPERREF                       
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 
%%%%
% Include experimental hyperref-compatibility code provided by Ross  
Moore,
% if the hyper option is requested.
\if at hyper@APA at comp% hyperref compatibility option is on
%


It seems that I've worked on this problem before!

In tracing your example, I did discover another problem though:

At line  1266  in the expansion of  \@@cite<#1>
there is an improperly coded test:

     \ifx\@empty#1%
     \else%
       {\ignorespaces #1\@BAP}%
     \fi%


This should really be:

     \ifx\@empty#1\@empty
     \else%
       {\ignorespaces #1\@BAP}%
     \fi%

since otherwise when #1 is empty (as in your example)
the comparison is between tokens  \@empty  and  \else .

In fact the required result is achieved, but for the
wrong reason!

Hope this helps,
