It seems that the default mode for outer (external file) references is
the "auto" mode. This one seems to load the whatever.pdf file, check the
named destinations and decide based on that.
I am not exactly sure why your example fails, because it seems desirable
that the auto mode detects the named destination and refers to it
instead, or at least refers to the page number the destination is
actually at.
In any case, you can try the "name" mode, which forces the use of
destination names (i.e. "/D (...)"):
% both inner and outer references in name mode
\setupinteraction[page=name]
% inner default (auto mode) and outer name mode
\setupinteraction[page={auto,name}]
Unfortunately, the second one doesn't work due to a typo in
strc-ref.lmt:
--- a/tex/context/base/mkxl/strc-ref.lmt
+++ b/tex/context/base/mkxl/strc-ref.lmt
end
if toboolean(outer) or outer == v_page or outer == v_yes then
outermethod = v_page
- elseif inner == v_name then
+ elseif outer == v_name then
outermethod = v_name
else
outermethod = v_auto
Other thing you can try Pablo, is to not actually have the destination
file (whatever.pdf) present when running context. This works, because if
ConTeXt can't find the file, the auto mode fails and you get named
destinations unless in page mode (`page=page`).
Whether something better can be done (and in a backwards compatible way)
at the ConTeXt side I am not sure, I didn't go that deep.

PS: Sorry if this message finds its way onto the list twice, I got
blocked by automoderation by initially also including the full
strc-ref.lmt file, which is too big.
