Stupid RMI is causing the problem.
I don't know why, but apparently having read-only attributes on the
client that get their value from the server side eventually corrupts
the EC.
I have a guess though.
Because this is a Java Client UI instead of web, these values that are
calculated on the server are being requested pretty-much continuously.
Every time you change windows, the UI asks for the values to be
updated. Switch to another app, update, switch back, update, select a
another tab in this window, update, change a value in another window,
update.
Update, update, update.
Because of the way JC works, it is copying the EC up to the server and
back down to the client every time I make a RMI request for the data.
In theory this shouldn't corrupt the EC, but apparently it does.
I guess I'll either have to go back to executing the code on the
client, or figure out a way I can do it stateless so the EC doesn't
need to be copied back and forth.

The odd thing is that this is the first time I've seen this happen,
and this part of the application is the same as it's been for 2
years. The only exception to that is that I changed a couple non-
model attributes to ask the server for values instead of calculating
them on the client. But these are the attributes it's complaining
about.
I'm going to remove stop the RMI and see if that gets it working
again...
