Hm, I looked at that code a couple of months back, and as far as I can
remember, "null" is what is returned in a static context: when in the main()
method, there is no 'this' to get. A second look seems to confirm that.
>From what I can understand of the code in beta2.2.9beta9.1, the relevant
method checks for the "null" and deals with it:
(defmethod jde-dbs-cmd-success-action ((this jde-dbs-get-this))
(call-next-method)
(let ((this-obj (oref this :data)))
(oset
this
:result
(if (string= (nth 0 this-obj) "null")
(jde-dbs-java-null "null")
(jde-dbs-java-udci
"this object"
:jtype (nth 0 this-obj)
:id (nth 1 this-obj))))))
My hunch would be that the check for (string= (nth 0 this-obj) "null") for
some reason doesn't work, or else that there is a mismatch between what the
Java side of JDEbug returns for a "get this" command and what the lisp side
expects (are you sure you're 100% on 2.2.9beta9.1 or 2.2.8, and that there's
no byte-compiled stuff or something else somewhere?). Guess the only one who
can resolve this is Paul himself.
