    Well... I don't use Click, but I do use deleteObject all the time with
    no issues.
    It looks like you're running into an API difference. The 3.0 API was
    relaxed from 2.0. In 2.0, deleteObject took an
    org.apache.cayenne.Persistent. In 3.0, it takes any java.lang.Object.

    See: http://cayenne.apache.org/doc/api/org/apache/cayenne/access/DataContext.html#deleteObject(java.lang.Object)
      (3.0)
    and: http://cayenne.apache.org/doc20/api/cayenne/org/apache/cayenne/access/DataContext.html#deleteObject(org.apache.cayenne.Persistent)
      (2.0)

    So, Click was compiled against 2.0 API, and you're supplying the 3.0
    runtime, I presume?
