 Browser jumps to first record after update

G'day Anton!

I had a similar occasion to want to return to the browse with the same
record highlighted. I raised the question during an IRC chat session.
What follows is courtesy of Pierre Tremblay, who kindly took the time
to come up with the following:

if GlobalResponse = RequestCompleted
  get(Queue:Browse, choice(?List))
  reset(BRW1::View:Browse, Queue:Browse.BRW1::Position)
  do BRW1::FillQueue


Anton, this also tested ok with me. To re-iterate Pierre's warning, it
should only be used where you are certain the record you are updating
cannot change one of the key components, so use with care.

I embed it into my code as a Routine called BRW1::RefreshLine. One day
I hope to write it up as a template extension, as I now found him a
very handy little routine to have around.
