Hi David,

It is a unidirectional relationship.

Entity Modeler and Eclipse aren't talking adequately to each other. My model will very often become out of sync. I guess the model file got corrupted sometime and I didn't notice it until the model was loaded.

Having a bad value in the “definition” attribute of the relationship’s entry of the Entity.plist is what probably caused the error. When you recreated it that cleared out the value.

Now, on the subject of a "one-to-one” relationship… Is it a true, bi-directional "one-to-one" where the FK in each table is also the PK? If so, that is not going to work.

Hi Chuck,

Never mind, I deleted the entity and recreated it with a new name and was able to circumvent the error.

I did not model the relationship as flattened neither did anything other then the usual for a one to one relationship.

From the stack trace, it looks like you modelled this as a flattened relationship and did it wrong.  Can you post the plist section for this?

Hi,

After simply adding a new entity and a relationship to an existing entity I get the following error:

Since the new entity is a very simple one (a list of options for another entity) I chose to implement it as a ERXGenericRecord. If I remove the relationship the application will start.

Any hint?

Angelo
