[JBoss Seam] - Instances get lost - strange behavior in conversational comp
by maku01
hi,
I've a really strange problem with a Seam Component which scope is "CONVERSATION"
I read a Entity List (roomList) with JPA in the case the member variable is null --> getRoomList().
Then I want to hold the instance as long the component exists.
When I operate on this component from the referencing view everything is o.k.
But when I change to an other view strange things happen.
When I return to the former view the Entity List (roomList) is not null but it is not the same as on creation.
This List has than null entries (as much as the "original" list).
The component instance is the same.
| @Name("roomMaint")
| @Scope(CONVERSATION)
| public class RoomMaint implements Serializable {
|
| private static final long serialVersionUID = 1L;
|
| private List<RoomEntity> roomList;
|
| private RoomEntity roomEntity;
|
| @In(at.hcare.service.base.ServiceNames.ROOM_SERVICE)
| private IRoomService roomService;
|
|
| @Logger
| protected Log log;
|
| @Create
| public void create() {
| log.debug("Create " + getClass().getName());
| }
|
| @Destroy
| @Remove
| public void destroy() {
| log.debug("destroy " + getClass().getName());
| }
|
| @Begin(join = true)
| public void start() {
| log.debug("start");
| }
|
| @Factory(scope = ScopeType.STATELESS)
| public List<RoomEntity> getRoomList() {
| if (roomList == null) {
| roomList = roomService.findAll();
| }
| return roomList;
| }
|
| @Factory(scope = ScopeType.STATELESS)
| public RoomEntity getCurrRoomEntity() {
| if (roomEntity == null) {
| creation();
| }
| return roomEntity;
| }
|
| public String save() {
| if (getCurrRoomEntity().isPersisted()) {
| roomService.update(getCurrRoomEntity());
| } else {
| roomService.persist(getCurrRoomEntity());
| }
| GenericFacesHelper.addSavedMessage("room");
| return NavigationOutcome.STAY_ON_SAME_PAGE;
| }
|
| public String remove() {
| return remove(getCurrRoomEntity());
| }
|
| public String remove(RoomEntity roomEntity) {
| if (roomEntity != null && roomEntity.isPersisted()) {
| roomService.remove(roomEntity);
| }
| return NavigationOutcome.STAY_ON_SAME_PAGE;
| }
|
| public void select(RoomEntity roomEntity) {
| this.roomEntity = roomEntity;
| }
|
| public String getDetailState() {
| return ExtendedResourceLoader.getText(isCurrNew() ? "new" : "edit");
| }
|
| public boolean isCurrNew() {
| return !getCurrRoomEntity().isPersisted();
| }
|
| public String creation() {
| roomEntity = roomService.createDefaultEntity();
| return NavigationOutcome.STAY_ON_SAME_PAGE;
| }
| }
When I change the context to "SESSION" it works as expected.
Could anybody give me a hint what is wrong?
TIA
Martin

[JBoss Seam] - @AutoCreate and create = true does not work
by gothmog
Hi,
I have two APPLICATION scoped components and one needs to be @In jected with the other, however I get
SEVERE: Error Rendering View[/cgsimulateentry.xhtml]
| org.jboss.seam.RequiredException: In attribute requires non-null value: entrySimulation.exAP
Seam recognizes the components and they are in the right scope as I can see this in the JBoss startup.
17:17:54,968 INFO [Component] Component: entryGate, scope: APPLICATION, type: JAVA_BEAN, class: model.EXAccessPoint
| 17:17:54,976 INFO [Component] Component: entrySimulation, scope: APPLICATION, type: JAVA_BEAN, class: model.EXSimulation
My two components look like this:
@Name("entryGate")
| @Scope(ScopeType.APPLICATION)
| @AutoCreate
| public class EXAccessPoint {
|
| @Logger Log log;
|
| @In EntityManager em;
| ...
|
| @Name("entrySimulation")
| @Scope(ScopeType.APPLICATION)
| public class EXSimulation {
|
| @Logger Log log;
|
| @In EXAccessPoint exAP;
| ...
What have I missed why can't seam auto create the EXAccesPoint class when it needs to be @in-jected into EXSimulation??
Thanks
Troy

and this are the classes source code of the EJB 3 bean
I hope you can find my problem.

xsl:import issue
by Alan Andrade
I have a xsl file in my ear application and it refers to another file in the same folder.
the reference is as follows:
<xsl:import href="BopResponse.xslt"/>
this does not work .
It throws the error :
Had IO Exception with stylesheet file:
.
Where should the files refer to ?
