Thinking a little more about this, it seems odd that the sorter is storing weight information for clients that are unknown to it. Why? It seems cleaner if the sorter only understands weights for its clients, rather than potential future clients. One way to resolve this would be to have roles with weights (but no allocations or frameworks subscribed to them) be present as inactive clients in the sorters, and using the existing interface. That seems to be in line with the approach in the next patch? - Benjamin Mahler On March 17, 2017, 1:12 a.m., Neil Conway wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
