OK, I've found my error:
After a relation is set via setRelation(), the column is rename 
according to the  "mappedtablename_displayedcolumnname"...and I was 
still using the original column name to set up my QDataWidgetMapper, 
that's why it didn't work....
But that's not all! It's still doesn't work with a combo box!
If I use a QLineEdit, then I get the right value. But I would like to 
have the same QComboBox as in the TableView...
