Hi Hans,
Arrays are not yet supported (elists are). If you want you can enter a bugzilla to give an extra
hint that support for arrays (of primitive types) is important.
As a workaround you can try to manually adapt a generated hibernate.hbm.xml. The hibernate.hbm.xml
is generated with a right click on the .ecore file and then select the submenu under teneo.

Hi Martin,
thank you for your answer! I've just made a bugzilla entry.
Within this I've also described a problem with EByteArray, which is a
EMF-predefined EDataType. I think this is a related problem.
greetings,
Hans

Hi Hans,
Support for arrays has been added in the version in cvs and will be available in the next build
(probably next week).
Other remarks:
- Only primitive type arrays are supported.
- Arrays are currently persisted in a separate table (so not serialized in one column/field).
- A byte array can be persisted as a blob using the lob annotation from jpa/ejb3.
This addition is done for both hibernate and jpox.
