I think what happened is that somehow, in a CVS transaction, an entity lost attributes that were destination attributes of relationships from other entities. The fact that the relationships involved were somewhat unconventional may have made the error even weirder.

EOModeler, of course, wouldn't let me add the attributes, because it kept giving me the error. But opening up the .plist and adding the attributes by hand seems to have put everything back in a stable state. Hopefully the weirdness of my relationships isn't actually causing any problems, and everything will work.

Has something lost its parent in an inheritance hierarchy?

I have made some changes to my model. They seemed to work, although they are a bit odd (I added a relationship in such a way that it can't have an inverse relationship; the inverse relationship wouldn't make any sense). Everything seemed to work for a while, but suddenly when I open up EOModeler and try to do some work, I get errors like this:
"Error: unable to add join {
sourceAttribute = {
columnName = ListID;
externalType = int;
name = listID;
precision = 10;
valueClassName = NSNumber;
valueType = i;
};
} to relationship participationAsToMany in entity IBCReadingList because the destinationAttribute's entity (Participation) doesn't match this relationship's destinationEntity"
Huh? Any idea what this means?
