Missed tsd:objectRef after Update

All,
During my development with tsd:objectRef I have a second problem related with the topic submitted as Xquery and tsd:objectRef behavior
http://tamino.forums.softwareag.com/viewtopic.php?t=5276.

After updating a document with references, its references are missed!! Why?..

For example, in this case I have a document with an Element called “Reference”, it has been declared as objectRef.

The document is inserted into Tamino with the dummy tag such as

SomeKey

And X-querying it, the referenced document is shown embedded in this tag, that’s ok. However after updating the Document (with the reference element) the reference is missed, it means the referenced document is not shown as an embedded document anymore.

Attached you can see the document before and after update

Thanks for your help and Time.
