A couple of issues I saw:

1. I think @Version should have a column mapping
2. The column for the @Id should be unique = true
3. You should always return the value from merge

Can you debug and guarantee that version and id fields are populated in your object before you call merge? If not, it will do an insert instead of an update...I think.
