Hello,
i use Hibernate 4.3.11 with H2 Database. I have a class in Java with several maps with annotations. Persisting works fine but my map in my H2 Database has no entries. What can be wrong?

Thanks.

Code:

@ElementCollection
@MapKeyColumn(name = "key")
@CollectionTable(name = "value", joinColumns = @JoinColumn(name = "sabilanz_id"))
@Column(name = "value")
private Map<String, String> sonstAnlagen;

My H2 Output

select * from saBilanz_sonstanlagen;
SABILANZ_ID VALUE KEY
(keine Datensätze, 8 ms)
