JSF’s <h:dataTable> vs <ui:repeat> – How to get the selected row.

So, a little while ago I was attempting to use JSF’s Facelets <ui:repeat> tag, as a replacement for <h:dataTable>, but difficulty came when I needed to process actions on individual records of each row. <ui:repeat> allows iteration over a List of Array[] of items, but it does not provide a method of discovering the “selected” or “actioned” row; there’s no way to discover the row the user is interacting with. Or is there?
