Hi Jonathan

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"



If I am reading properly, EOModeler expects an attribute listID with the properties above in the Participation entity, but it is not there or it has different properties.


Hope you can go further with that,

Huh? Any idea what this means?
