Hi Chuck,

From your descriptions, it sounds like the models are not getting
connected with the same connection dictionary. Try using the
EOUtilities method:
public static EODatabaseContext
databaseContextForModelNamed(EOEditingContext ec, String name)
To get the EODatabaseContext and EODatabase from each model and
test if they are the same objects or not. They should be the same.
I did what you suggested. I added the code to execute as soon as
Main component is loaded. I get the following result:
Database context for model A:
[EMAIL PROTECTED]
Database context for model B:
[EMAIL PROTECTED]
Is database context equals? true
So, they are equals. That it is not the problem. Wait... I tried to
search and edit an object with the problem I described.
Surprisingly, it worked. Problem solved. Let me remove the test code
I added. Stop the application, start and... I can't edit the object
again because of the same exception I've reported.
So, if I leave the code to test database context equality at
session's startup, the application works. If I remove the code, I
get the exception. I tried 3 times both situations. The exception
always appears when there is no test code. And the application
always works when the test code is there. Weird.
Any ideas? :p
If the models are not connected, I think this code will cause them to
connect. Is this running before or after the code you added to
connect models? You really want it to run after (well, really, want
your model connection code to run as early as possible so that it
catches and and all notifications). I am guessing that perhaps your
model connection code is running too late and so not affecting one (or
both) of the models.
