Hello Peter;
You expect that you mean to lock the OSC? I thought that the OSC
gets locked when you lock the EC?
No, of course not. An ec (the defaultEditingContext) gets locked each
time the session is awoken. If this locked the OSC, concurrent
dispatch would not be possible. The OSC only get locked while
fetching or saving.

Im not sure if it is safe or not, but i would lock/unlock around
the call to the setUserInfoForKey() method.

Hello;
I want to put some data into the user info of an object store co-
ordinator and then pull it out again in notifications.
ec.lock();
try
{
ec.rootObjectStore().setUserInfoForKey(xyz,"foobar");
try
{
// do some editing context foo here!
}
finally { ec.rootObjectStore().setUserInfoForKey(null,"foobar");
}
finally { ec.unlock(); }
That should be safe should it not or am I playing with fire?
cheers.
