Embedded attributes are handled incorrectly

[IskandarovRost]

1) Create an Embeddable entity Address with several lines 2) Create an entity "Customer" 3) Embed the Address to Customer

...
public class Customer extends StandardEntity {
    private static final long serialVersionUID = -6557138342855944171L;

    @Column(name = "GRADE")
    protected Integer grade;

    @Column(name = "NAME")
    protected String name;

    @Embedded
    @EmbeddedParameters(nullAllowed = false)
    @AttributeOverrides({
            @AttributeOverride(name = "line1", column = @Column(name = "MAIN_ADDRESS_LINE1")),
            @AttributeOverride(name = "line2", column = @Column(name = "MAIN_ADDRESS_LINE2"))
    })
    protected Address mainAddress;

    @Embedded
    @AttributeOverrides({
            @AttributeOverride(name = "line1", column = @Column(name = "DELIVERY_ADDRESS_LINE1")),
            @AttributeOverride(name = "line2", column = @Column(name = "DELIVERY_ADDRESS_LINE2"))
    })
    protected Address deliveryAddress;

4) Create a view containg all the fields of Customer and addresses 5) Create React frontend client using Studio 6) Create 'Entity management' for Customer, select the view 7) start the application

AR: on customer editor the controls for addresses are as like it is a link or enum;

ER: Vaadin editor is generated simply with this fields on form

After the fix of #36 Embedded attributes are still lookups

[IskandarovRost]

And could not save a new instance with embedded attribute 1) "Full entity" has embedded "Address"

public class FullEntity extends StandardEntity {
    private static final long serialVersionUID = 2052734884961142284L;

    @Embedded
    @EmbeddedParameters(nullAllowed = false)
    @AttributeOverrides({
            @AttributeOverride(name = "lineOne", column = @Column(name = "ADDRESS_LINE_ONE")),
            @AttributeOverride(name = "lineTwo", column = @Column(name = "ADDRESS_LINE_TWO")),
            @AttributeOverride(name = "postcode", column = @Column(name = "ADDRESS_POSTCODE"))
    })

    private Address address;

2) Create React module: Address.ts FullEntity.ts 3) Create Entity management 4) Create a new instance of the Full entity.
