I keep getting this returned via the debug page under my datamodel component. Why is the
row unavailable? The wrapped data is some of the data returned via my query but the data
model is not being displayed on the page. No exception is thrown.
class class org.jboss.seam.jsf.ListDataModel

Here is my SFSB
