Dave,
could you post the rest of the stack? Looks like the fault fires on
deserialization, i.e. too early in the container lifecycle when there
is no DB connection yet. Normally this shouldn't happen. I wonder
what causes it; and the answer might be a few steps up the stack trace.

I am currently having problems when trying to use Cayenne 1.2 along
with Tomcat's (v5.0.28) session restore capability. That is to say,
if I deploy new code and restart tomcat, it saves the session data
instead of starting with all new sessions when it starts up.
My problem is that I used to be able to restart and stay logged in
using version 1.1. Version 1.2 seems to have problems with trying to
look up data after I have restarted Tomcat, and I get this stack trace
caused by a NullPointerException:
org.objectstyle.cayenne.access.ObjectStore.resolveHollow
(ObjectStore.java:945)
org.objectstyle.cayenne.access.DataContext.prepareForAccess
(DataContext.java:1842)
org.objectstyle.cayenne.CayenneDataObject.readProperty
(CayenneDataObject.java:238)
I couldn't find anyone else with this problem, so I assume I am doing
something wrong and it's not a bug. Any ideas?
