Hola everyone!
I have small core data non-document-based app.
I used the data modeler to create an entity "myEntity" with few attributes.
Then I made the interface in IB where for each of those attributes there is
a text field.
Then I dragged NSObjectController from IB palettes to instances pane, named
it myController and I bound its managedObjectContext to myAppDelegate (from
data modeler) with model key path: managedObjectContext and in attributes
pane i checked mode: entity, entity name: myEntity, automatically prepares
content: yes, editable: yes.
Then I bound every text field's value to myController with controller key:
selection and with model key path: name of myEntity's attribute.
Now, the problem is, it doesn't work. I always get "no selection" in all
fields.
Please, what am I missing? What am I doing wrong?
