> If a page references a property of the back bean, then using <s:link> or <s:button> action to delete the last row of data backed by a DataModel will cause an exception with the following root cause:
> java.lang.IllegalArgumentException
> 	javax.faces.model.ListDataModel.getRowData(ListDataModel.java:139)
> ......
> This bug recurs when we make the following modifications to the 'messages' seam example :
> 1. Add a property 'title' to the MessageManager bean.
> 2. In messages.jsp, change the header 'Message List' to '<h:outputText value="#{messageManager.title}"/>'
