Then I dragged NSObjectController from IB palettes to instances pane, named

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?

Did you create an instance of the entity?
