Hello Nicola!

Thanks for your instant help!  I'm making some promising
advances with the EOAssociation connector.  Binding a text field
to a database via an EOControlAssociation is working here now!
I haven't factored out the new classes into a seperate library,
but will do it after I have implemented some more.

When trying to make EODisplayGroups available to Renaissance, too,
I stumbled over the following:

EODisplayGroups have an property fetchesOnLoad which, when set to YES,
tells them to issue a fetch to their EODataSources after they have
loaded from a nib (resulting in a fetch from the database).  In Mulle's
implementation of EOInterface, this is done in
-[EODisplayGroup awakeFromNib], I don't know where it's done in
Apple's version.  To be able to use this feature, I suggest the
following patch to GSMarkupAwaker.m.  That way, the platform object
can be a real EODisplayGroup and not a subclass which implements
-awakeFromGSMarkup.  Yet I don't know if that would harm some other
platform objects.

Cheers, Dirk.
