> While the renaming of db relationships leaves the corresponding obj relationships without
renaming and this may be not user-friendly, but doesn't cause the error, there exist the problem
with flattened obj attributes. For example, let there is a dbEntity "DbEntity" with db relationship
"rel" and some attribute, which dbpath goes through this relation: attr_db_path="rel.some_property".
 So, when I change name of relationship from "rel" to "anotherRel", the table of object attributes
is redrawn incorrectly(empty cells), and on attempt to save there fails an error:
> org.apache.cayenne.exp.ExpressionException: [v.3.0-SNAPSHOT Jul 28 2010 10:27:31] Can't
resolve path component: [DbEntity.rel].
