OK, I'm answering my own question. (Hopefully this will
redeem me for some of the stupid newbie questions I've asked so far
and which have been very patiently answered by the gurus--mostly
Peter G.)
I just tested context sensitivity on a merged webhelp project
created in RH7 and using IE 7 and it works!!!! Yahoo!!!
**I used the Javascript call from a web page to test.
**I've only tested the RHShowHelp() function using the
HH_HELP_CONTEXT parameter
**I've brought up the default topic (which is the first topic
in the first merged project--the one that is redirected to from the
parent project).
**I've brought up a specific topic with no nav pane based on
map ID.
As mentioned, I followed Greg Minter's instructions from 2006
posted on PG's site. However, here are some clarifications/changes
to those steps (please forgive me if anybody already knew this
stuff):
***You don't have to manually copy and paste the Map IDs from
the Map ID (*.h) files of the child projects into the Map ID file
of the parent project. Just generate the parent and child projects
as usual and the references are automated.
***[Concommitantly] You don't have to manually place the Map
ID (*.h) file in the output folder (mergedprojects\projectnnn), as
he describes.
Woo Hoo.
