It sounds like you created an entity named Image in your model, modeled a to-one relationship to ERAttachment, but forgot to uncheck the reverse relationship from ERAttachment to Image. You should only make that a one way relationship
Image -> ERAttachment
not
Image <<-> ERAttachment
ERAttachment can’t find Image because it doesn’t import your framework with the Image entity.
