Hi JR,
First of all I suggest upgrading Cayenne to the current nightly build
version if you haven't done so already.
CM is much more stable now then it was in Alpha 2. Among other things there
is a fix of a very nasty bug in CM, leaving much less chances for the map
project files corruption:

Besides it adds logging of exceptions and other debugging info to
$HOME/.cayenne/modeler.log
As for your problem, I haven't seen this particular one, but in general
there may be problems when removing things in "Db*" layer when they are
already mapped in "Obj*" layer. Dead objects may be hanging in the memory
and even get saved. As a workaround I suggest unmapping corresponding
"Obj*" objects first, and then removing "Db*". I think we may even need to
change the internals of the DataMap structure to fix it (without changing
the public API and XML format of course).
Andrus
