Gotcha. So it had to do with server version. Makes sense. You never
deployed the 4.x server from trunk?

Wonderful. Glad to hear it.

To get access to the methods in 3.x it's necessary to cast to
ExperimenterIPtr:

  ExperimenterIPtr::dnyamicCast(im-<second);

Alternatively, you can access these fields directly: 

   user->id

but this is generally not suggested and is the reason that direct
access disappears in 4.x.
