Subject [jira] [Created] (CAY-2661) NPE on DB Import screen
Date Sat, 06 Jun 2020 07:41:00 GMT
Andrus Adamchik created CAY-2661:
------------------------------------

             Summary: NPE on DB Import screen
                 Key: CAY-2661
                 URL: https://issues.apache.org/jira/browse/CAY-2661
             Project: Cayenne
          Issue Type: Bug
          Components: Modeler
    Affects Versions: 4.2.M1
            Reporter: Andrus Adamchik


There are some preconditions to this exception that I can't reproduce anymore. I was playing
with regex for DB Import table name match, and the Modeler was misbehaving somehow (wouldn't
let me enter certain forms of regex, etc). Then I deleted that probelmatic include and tried
to add a new one. That's when the exception happened.
