Does cuba platform support collections of embedded entities (@ElementCollection )? I’m guessing not because it’s not supported by the UI, but just thought I’d ask.

Hi @marc ,
I think this issue has been moved to github:
opened 09:31AM - 08 Nov 16 UTC
type: enhancement
''Possibly some of other JPA 2.0 features are also not supported by the platform… . ''
1) Create an embeddable class 'Expositions'
2) Create the corresponding table in the database
3) Create an entity 'Artist'
4) Add embeddable collection of the 'Expositions' to the 'Artist'-entity, as in the code below
```
public class Artist extends BaseIntegerIdEntity {
private static final long serialVersionUID = 2969222955466032141L;
@Column(name = "NAME", length = 30)
protected String name;
@ElementCollection
@CollectionTable(name = "aliases", joinColumns = @JoinColumn(name = "artist_id"))
@Column(name = "alias")
private List<String> aliases;
@ElementCollection
@CollectionTable(name = "expositions", joinColumns = @JoinColumn(name = "artist_id"))
private List<Expositions> expositions;
```
5) start the server
*AR:* embedded collection of primitives works well but embedding a colection of user defined type leads to the exception:
