Hi Bill,
The second one of your suggested changes (the one I've quoted below)
stopped the exception from occurring. I assumed that you meant to only
use one of those changes, and the change to clearBranch() is not needed
if the change to getBranch() works. Is that correct?
Thanks for your quick response.
