No, it is not a bug, it is the way ooRexx works. As you have probably
figured out in your mind. You have an object, the ooRexx object that
is your dialog subclass. You can only invoke public methods on that
ooRexx object. This of course is no different than in any ooRexx
code:
m = .Miesfeld~new
m~fullName
m~secretName
::class 'Miesfeld'
::method fullName
say 'Mark Miesfeld'
::method secretName private
say 'Mr President, sir'
The underlying ooDialog implementation code has a reference to your
dialog subclass. It invokes the event handler by sending a message to
that dialog subclass object. It knows the *name* of the message
because you have to specify the name, (or use the default name,) in
your connectXXXEvent() method. If you supply a private method name,
then it won't work.

Sure, it's worth mentioning. If it raised a question in your mind,
I'm sure there are other people starting out that would have the same
question.
