Be warned, we recently discovered a bug when we change the dictionary
for the default model group ( EOModelGroup.defaultGroup().models() ) at
application launch time (in application contructor for example).
PROBLEM : Unfortunately, EOF sometimes load a model more than once,
even though a model is already loaded in the default model group.
For example,
EOUtilities.rawRowsForSQL(ec, "MyModelName", sqlQuery, null);
will cause a new loading of the model named "MyModelName", it won't use
the one already loaded in the default model group.
So you have to change the connection dictionary every time a model is
loaded and not change the ones in your default eomodel group only at
launch time.
To change the dictionary every time a model is loaded, you have to
listen you a notification sent with the id
EOModelGroup.ModelAddedNotification, like :
NSNotificationCenter.defaultCenter().addObserver(myObserver, new
NSSelector("notificationModelLoaded", new Class[]
{NSNotification.class});, EOModelGroup.ModelAddedNotification, null);
...
public void notificationModelLoaded(NSNotification notification) {
EOModel model = (EOModel)notification.object();
adjustEOModelFromProperties(model);
}
Project wonder does it using notifications, so you can look at their
code if you need more details.

I'd like to set the connection URL, UID, PWD, etc. to my dbase at
runtime.
Is there a good reference/class/method for handling this?
