I'd say it's a yaql bug (commented on the bug opened in Heat), that can work around using the list_merger argument: $.data.l.reduce($1.mergeWith($2, listMerger => $1.toList() + $2.toList())) Still slightly more elegant than the one I came up with. -- Thomas __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
