Subject: [PATCH] Dev fix: _pluck should check that what is is accessing exists

- When using _pluck with deferred rendering, there were a number of
  errors due to the nTr element being undefined (that's what deferred
  rendering is all about of course). So the logic to check that pluck
  can pluck from a source object needs ot be added.
