Hunter,
Coincidentally, I was getting the same error message with an Oracle
database a few days ago.
It looks like EOModeler's reverse engineering of tables consisting of
only primary keys (e.g., many-to-many linkers) doesn't work. It seems
like it's looking for non-key columns, and when there are none, it
craps out. You should get a slightly more descriptive error message
(java.lang.NullPointerException in an EOF method - I can't remember
which) if you first reverse engineer only table(s) that contain non-key
columns, then select one of the offending tables via in the File > New
Updated Model menu.
To work around it, you can either import the safe tables fist, and add
the PK-only tables by hand, or add dummy non-PK columns to the PK-only
tables (of course, don't include the dummies in your model). We added
dummy columns.

I am trying to check out WO. I installed 5.2.1 on my TiBook (Jaguar).
I was playing with EOModeler and I was hoping it could take a look at
my database and do a little modeling for me.
I am able to connect to my DB (PostgreSQL 7.3.3 over JDBC) and it can
read the table names. I select all tables and then it goes to the
database (I can see the database output on my DB console window).
Then, I get an error message: "Connection Error - No reason provided".
This isn't much help. I searched the archives at lists.apple.com (not
the greatest search interface) and couldn't find an answer.
Any ideas why this isn't working?
Thanks.
Hunter
