DataTable of List T gives empty results

Question

Logs in tomcat shows that getList() in Beatles indeed logs the text of a List to tomcat, and, because it's a List<Beatles>, it must be "correct" in its model. Is there some reason why a DataTable wouldn't display such a List<Beatles>? The resulting view is just an empty table :(

Answer 1

Here are the JSF components, which, from experience, I know work with this model. I'll go back to populating the data "by hand" just play around with it, but don't see how a change in how the list is populated would matter:
