relation one-to-one unrecorded

Hi all, I have two entities with a one to one relationship, the entity 1 has marked the check owner, I created a view for the entity 2 with one property it includes Entity 1, when on a screen I edited a Entity2 and selected a Entity1 in the combo does well but leave the screen is not recorded. Where am I wrong?
Thanks and regards.

Could you provide a small project which demonstrates the problem?

Konstantin apology was my mistake, it works perfectly.
