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?

Trying to delete object entities with Cayenne 3M5 doesn't seem to

I'm getting the error message:
java.lang.NoSuchMethodError:
org.apache.cayenne.access.DataContext.deleteObject(Lorg/apache/
cayenne/Persistent;)V
Is there something different in 3.0 about deleting objects since 2.0?
I was just using:
http://incubator.apache.org/click/docs/extras-api/org/apache/click/extras/cayenne/CayenneTemplate.html#deleteObject(org.apache.cayenne.DataObject)
as before. That method from CayenneTemplate just calls
DataContext#deleteObject(Object).
thanks,
Joseph.
