Re: [OT] jsf dataTable scope.

[Mark Lowe]

I think i found my answer and its basically scope to session and set 
the StateManager to save on the client.

<context-param>
   <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
   <param-value>client</param-value>
</context-param>
This stores session information on the client rather than on the 
server..

I found it when i was read the jsf spec..
[McClanahan et al, JavaServer TM Faces Specification, February 2004, 
Revision 01, page 242]

" javax.faces.STATE_SAVING_METHOD -- The location where state 
information  is saved. Valid values are “server” (typically saved in 
HttpSession) and “client  (typically saved as a hidden field in the 
subsequent form submit). If not specified,  the default value “server” 
must be used. "

I was trying to fix something that's already been done, all i have to 
say to that is "arses".

Does any one have any thoughts on scoping a List backed backing bean 
to request and being able to maintain the list without the Bean being 
reinstantated on each post..

public class HouseBean {
        
        private List roomList;
        public HouseBean() {
                this.roomList = new ArrayList();
        }
        public List getRooms() {
                return rooms;
        }
        //also tried using void method
        public String addRoomAction() {
                this.roomList.add(
                        new RoomBean(
                                        "Room "+ Integer.toString(roomList.size())
                        );
        return Outcomes.SUCCESS;
        }
}
<h:form id="houseForm">
        <h:dataTable id="table" var="roomBean" value="#{houseBean.rooms}">
        <h:column>
                <h:inputText id="room" value="#{roomBean.name}" />
        </h:column>
</h:form>
The first item works but then the bean is instantiated and I get a new 
List..

DO i need to scope to session or is there something i've missed? I've 
tried lazy list but the basic problem is that the Bean is instantiated 
everytime the addRoomAction is run..
