Some observations, for what they're worth:
I've found that the Component Manager always finds new or changed AUs
if I
drag them into a Components folder in Finder. If the components have
more
or less "gradually appeared" via building them in Project Builder into
the final location for the first time, then I almost always have
problems,
but I can solve the problem by dragging the component out and then back
inside in Finder. I definitely don't know the underlying technical
issues, but it seems to me that there is some sort of monitoring of the
special enchanted locations where copying or moving activities will be
noticed. Perhaps the installer does those in a way that is not
noticed by
this monitoring.
That's an interesting observation - there probably is a watch placed on
those directories by the coreservciesd (that does the component
registration)
That would be a good thing to bring up on a Carbon list to get this
confirmed...

Anyway, I don't know if this is all of much use, but I've recently at
least found that rebooting doesn't ever seem to be required and that,
in
those bad situations, simply manually dragging out and dragging back in
the component will make it become known. I wish that I could find a
better solution (certainly that makes for a not so useful installer),
though.

Hi,
I've a well known problem : I put an Audio Unit (with my
installer) in the component folder, but it is sometimes not
recognized by CoreAudio when starting Logic. In the worse case,
rebooting computer will correct the problem.
The questions are :
- is there finally a new method to do in my installer to notify
CoreAudio that something has changed ?
- or should I state that this is a bug of CoreAudio that will be
solved later ?
- or should I ask the user for a reboot systematically ?
I know those questions have been already discussed, but I wanted
to know if there were anything new on that issue.
Thanks,
Raf
