Object Cache
Hi List
I'm using cayenne 3M4.
I'm a but confused with how to handle the cache.
I have two objects A related to B in a one to many relationship.
when I add objects B objects related to A, and immediately in a
subsequent call ask for those B objects related to A, the new B objects
are not present, though they are after trying the call again after a few
seconds.
To fix it, once I added a B object to A's B objects, I set object A as
hollow, so
that the next time A is used, it reloads...
Is this the right way to make objects refresh their cache ?
Its a web application, and the same dataContext is used in the different
calls that
use object A.

I first need to make sure it's not a stupid being done by me.
I'll see if I can put an easily repeatable small example together on the
weekend, and post the
code from that rather.

This should work within the sane DataContext - you should see the
object on the opposite end of relationship immediately. Can you post
the relevant code that you are using to set and check the
relationship? Also what happens in these few seconds (i.e. if this is
a web application, does it happen in the same request)?
