Ok, a few more details. The entity itself is not a Seam component, so it doesn't have a Seam context. The Java Bean I'm talking about is a SESSION scoped Seam component that simply holds the Set of entities. I did add the entity to the Set, but my DataTable doesn't display it. Also, refreshing it from the database would be a little overkill, since it's already in the Set. When does the DataTable read the contents of the Set annotated with @DataModel?
