So instead of using DataModel and DataModelSelection, I saw that this is being used with the idea of using a RequestParameter and a param in the link. I tried that and it works nicely. Is this going to be the future model here, as a replacement for the DataModel / DataModelSelection thing? In some ways using the entity ID as a param is a little more clear to me, but that may be because it's familiar from the "old days" (Servlets, JSP, PHP, etc) of the web.
