I'm using a rich:dataTable in my JBoss Seam application with a map as value and I was just trying to change it into a rich:scrollableDataTable, but when I did, I got this error:

Property 'key' not found on type org.jboss.seam.jsf.MapDataModel

I searched, but couldn't find anything on this and it's not in the documentation either it seems, so: Does it not work with a Map at all? Is it that different from rich:dataTable then?
