Going back to 1/

I need to initialise the "allocations" and this is generally done by a @Factory.

This causes a stack Overflow...


  | @SuppressWarnings("serial")
  | @Scope(ScopeType.SESSION)
  | @Name("allocations")
  | public class Allocations implements Serializable {
  | 
  | 	private List<Day> indoorArenaDays;
  | 	private List<Day> dressageArenaDays;
  | 	private List<Day> sjArenaDays;
  | 
  | 	@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
  | 	@Factory(scope=ScopeType.SESSION, value="allocations")
  | 	public void init() {
  | 
  | 		List<DaySlot> indoorArenaDaySlots = new ArrayList<DaySlot>();
  | 		DaySlot daySlot = new DaySlot();
  | 		daySlot.setBooked(true);
  | 		daySlot.setBooker("Billy");
  | 		daySlot.setBookingId(1l);
  | 		daySlot.setReason(BookingReasonsKind.ONE_HOUR_PRIVATE);
  | 		daySlot.setTitle("This is a test");
  | 		indoorArenaDaySlots.add(daySlot);
  | 
  | 		Day day = new Day();
  | 		day.setDate(new GregorianCalendar());
  | 		day.setDaySlots(indoorArenaDaySlots);
  | 		indoorArenaDays = new ArrayList<Day>();
  | 		this.indoorArenaDays.add(day);
  | 	}
  | 
  | 	@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
  | 	public List<Day> getIndoorArenaDays() {
  | 		//init();
  |     	return indoorArenaDays;
  |     }
  | 	
  | 	@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
  | 	public void setIndoorArenaDays(List<Day> indoorArenaDays) {
  |     	this.indoorArenaDays = indoorArenaDays;
  |     }
  | 	
  | 	@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
  | 	public List<Day> getDressageArenaDays() {
  |     	return dressageArenaDays;
  |     }
  | 	
  | 	@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
  | 	public void setDressageArenaDays(List<Day> dressageArenaDays) {
  |     	this.dressageArenaDays = dressageArenaDays;
  |     }
  | 	
  | 	@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
  | 	public List<Day> getSjArenaDays() {
  |     	return sjArenaDays;
  |     }
  | 	
  | 	@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
  | 	public void setSjArenaDays(List<Day> sjArenaDays) {
  |     	this.sjArenaDays = sjArenaDays;
  |     }
  | 
  | }
  | 

This little class started as a POJO (used by my ResourceAllocationController) as it really didn't need to be a Seam Object (or so I though).... Anyhow now its a fully grown up Seam object.

So... How do I get the Factory to work?

Do I need and Interface and make this a body (impl)?



This is the .xthml that calls it.... (and as such expects allocations to be set up - by the factory).


  | <h:panelGrid class="left" id="day_slots_choices" width="20%">
  | 	<rich:dataTable var="eachDayForIndoorArena" value="#{allocations.indoorArenaDays}"
  | 						rendered="#{not empty allocations.indoorArenaDays}">
  | 		<rich:column width="10%">
  | 			<f:facet name="header">
  | 				<h:outputText id="resource_date"
  | 					value="#{messages.allocation_day}" />
  | 			</f:facet>
  | 			<div class="centre">
  | 				<h:outputText value="#{eachDayForIndoorArena.date}">
  | 					<s:convertDateTime type="date" dateStyle="full"/>
  | 				</h:outputText>
  | 			</div>
  | 		</rich:column>
  | 	</rich:dataTable>	
  | </h:panelGrid>
  | 

If I hack the getXXX then the init will be called, but then it gets called every time.


CONFUSED....
