[Rhythmbox-devel] bonobo-a-s issue for applet

Hi folks,

FYI.  This is the thing that has been holding up RB applet development. 
   Unfortunately, there are only a few days before the API freeze.

Anyone have any thoughts or suggestions on this?

	Urk - it's possible of course that we arn't flushing the client side
cache when a new thing is activated; quite possibly this is a bug, in
the client side caching. We should prolly scan the query string for
'_active' and not hit the cache for this case in:


	since flushing every client cache every time something new was
activated would be far too expensive. Any chance of a nice tested patch
that does that ?

	Sure - it had no cache.

	Sure; that can be done: simply add 3 new methods to the idl in
libbonobo/idl/Bonobo_ActivationContext.idl one on the client, two on the
server - to add/remove a listener and recieve an event and hook them up
in activation-server / bonobo-activation.

	NB. if you want this API in - you have ~5 days to get it done before
we're freezing the API for Gnome 2.6 though ... [ I'd appreciate a
separate patch to the above simple _activate cache fix ].

	Looking forward to some nice unified diffs :-)
