NPE on attempt to create an instance of entity with composite PK using Entity inspector

[haulmont-git]

Test project is attached

1. Create an embeddable entity for a composite PK

@NamePattern("%s %s %s|keyOne,keyThree,keyTwo")
@MetaClass(name = "emailertst$PKEntity")
@Embeddable
public class PKEntity extends EmbeddableEntity {
    private static final long serialVersionUID = -3608909441815047991L;

    @Column(name = "KEY_ONE")
    protected String keyOne;

    @Column(name = "KEY_TWO")
    protected String keyTwo;

    @Column(name = "KEY_THREE")
    protected String keyThree;

2. Create an entity with composite PK on the base of the previous entity

@NamePattern("%s|utilInt")
@Table(name = "EMAILERTST_CPK_ENTITY")
@Entity(name = "emailertst$CPKEntity")
public class CPKEntity extends BaseGenericIdEntity<PKEntity> implements HasUuid {
    private static final long serialVersionUID = 5603151601450508286L;

    @EmbeddedId
    protected PKEntity id;

    @Column(name = "UTIL_STR")
    protected String utilStr;

    @Column(name = "UTIL_INT")
    protected Integer utilInt;

    @Column(name = "UUID")
    protected UUID uuid;

3. Start the application
4. Using Entity inspector create an instance of the entity
5. Open the browser of Embeddable ID Entity by clicking "..." in the pickerField

6) on the embeddable PK entity browse screen press "Create"
