I saw a lot of similar topics in the forum, but so far I can’t understand why this is happen.
A little bit more.
CardItem entity:
@NamePattern("The document in the following state: %s|cardState")
@Table(name = "DEMO_CARD_ITEM")
@Entity(name = "demo$CardItem")
public class CardItem extends StandardEntity {
private static final long serialVersionUID = -3956149009965224251L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="ID")
public UUID getId() {

}

// SKIPPED
}
CardSubType entity (sorry for the field names - see Hibernate - PropertyNotFoundException: Could not find a getter for):

I can create cards - all OK, without exception. But when I open the screen with a table to view - card-item-browse - the following message always appears:

If I deleted these fields from the card-item-browse.xml descriptor:
<column id="cardType"/>
<column id="cardSubtype"/>
Then everything works fine.
What could be the problem?
I would be very grateful for the information. Thanks to all.
