-----------------------------------

             Summary: NullPointerException doing sync in ObjEntity with null target in dbRelationship
                 Key: CAY-2071
                 URL: https://issues.apache.org/jira/browse/CAY-2071
             Project: Cayenne
          Issue Type: Bug
          Components: Modeler
    Affects Versions: 4.0.M3
            Reporter: Olga Bondareva


Bad idea to pass null into java.util.StringTokenizer (in our context bad idea to create objEntityName
from null))

When we create new dbRelationship and don't add a target dbEntity and then from objEntity
try to do sync:
