Have you read the relatively good documentation on shared editing
contexts? They are intended for a specific purpose---mainly, if you
want to make changes to an object in a shared EC, you have to do it
in a specific way. Myself, I've always found shared ECs to be too
cumbersome, and too confusing to figure out how to use them properly,
and I don't use them. This may depend on the nature of your app
though; many people have found them very useful, reportedly.
And now I'm having trouble finding the documentation on shared ECs
that I know I've read before and found enlightening... Well, there's
a brief discussion at the top of the EOSharedEditingContext
documentation itself:
http://developer.apple.com/documentation/WebObjects/Reference/API/com/webobjects/eocontrol/EOSharedEditingContext.html
I could have sworn there was something in the EOF book too, at:
http://developer.apple.com/documentation/WebObjects/Enterprise_Objects/index.html#//apple_ref/doc/uid/TP30001011
But now I can't find anything.

Currently I have a problem with my editing contexts. The non-shared ones

with each other causing all kinds of grief. I'm sort of loathe to just
blanket turn off the shared context as my
application is read-mostly.
So, I'm asking what is the best way to keep the shared contexts happy? My
latest attempt is to just
invalidate all objects in both the updatable and the shared context. But
I'm concerned that that may
be too extreme and cause a whole bunch of unnecessary database traffic.
Should I just refault everything?
Or should I just give up on the shared contexts?
Thanks in advance
