[Eg-newdevs] get_tcn function scope

[Josh Stompro]

Terran, I think the get_tcn function is in scope... it just doesn't return
a value.  I followed the code in the developer console and it does grab the
tcn.

The function sets the $scope.local_overlay_target_tcn to be equal to the
found tcn value.  But it doesn't return it.

    function get_tcn(currTarget) {
        egCore.pcrud.retrieve('bre', currTarget, {
            select: {bre: ['tcn_value']}
        }).then(function(rec) {
            $scope.local_overlay_target_tcn = rec.tcn_value();
        });
        return;
    };

Maybe the function should just return the value... and then instead of just
calling it like

  } else {
            $scope.local_overlay_target = items[0]['bibid'];
            var currTarget = items[0] ['bibid'];
            get_tcn(currTarget);
        }

You would use

  } else {
            $scope.local_overlay_target = items[0]['bibid'];
            var currTarget = items[0] ['bibid'];
            $scope.local_overlay_target_tcn = get_tcn(currTarget);
        }
