Hi,

First of all, I apologize if this question has already been asked before. I have been struggling to get the simply search list to work with my current project using Seam with Ajax4JSF. I pretty much follow the example in HotelBooking to implement my search function. I have dumped a lot of output at different breakpoint in the code and traced all the way to the .xhtml page. It seems, the dataTable is not displaying the actual rows even though I was able to get the number of records from the database. The column headers rendered probably, but just no data being displayed below. I am not sure what i did wrong and greatly appreciated any enlightenment.

My Search code are the followings:-

package action;

import static org.jboss.seam.ScopeType.EVENT;
import static org.jboss.seam.ScopeType.SESSION;
