MacOS, R 3.5
So, I had an RCP (developed in 3.4, on WinXP), and now have checked out
all its plug-ins in 3.5 MacOS
(eclipse-jee-galileo-SR2-macosx-cocoa-x86_64.tar: I have a 64-bit Mac,
so there is no 3.4 available).
I'm using the Common Navigator framework.
I run the RCP (after deleting from the .product file the win32 fragments
and adding the MacOs fragments), and ... my runtime workspace is empty.
That is surprising, to me, because I have also copied my whole WS from
the WinXP machine, including the .metadata directory (although the
Finder hides that).
Worse, if I create a new project in my WS, shut down the RCP and restart
-- the newly-created project is gone. I can see it (and all the others)
in the Finder.
What is going on here?
thanks
Paul

Workspaces do NOT support being copied/moved around, especially from one
system to another, or from one operating system to another. That's
likely the root of your problems.

OK, fair enough: user error. I have now tried in a fresh runtime-WS, and
there is no problem with persistence; I have then also exported from the
runtime Eclipse/RCP on the PC one of the projects in question, and then
imported it into the runtime Eclipse/RCP on the Mac -- and all is fine.
I fell into this user-error b/c a lot of people in my group here often
do move WS's around and copy them (never before from PC to Mac), and
have usually had success. I'd been suspcious, and rarely did it ... it
turns out my suspicion was correct.
Now -- where can I point them in the Help docs or the like to an
explanation of why this is a bad idea? (My single experience that it is
a bad idea is likely to get dismissed as a fluke or a special PC-to-Mac
issue).
thanks

Tell them to come ask here - the answer is always consistent: "Don't
copy or move workspaces, they're not designed for it and you're asking
for headaches." :-)
More seriously, this page has the following blurb, although it's sort of
a weakly made point and not really in the context you're looking for:
"You should not copy or move the workspace directory..."
