[jboss-user] [JBoss Seam] - Re: Facotry-session and bean-conversation
I found the solution. I forgot the "return orders".
| @Factory(value="orders", scope = SESSION)
| public List findOrder(){
|
| Query query;
|
| query = em.createQuery("select o from Order o where
o.customer=#{currentContact.customer}");
|
|
| orders = (List) query.getResultList();
| return orders;
|
| }
|
Thanks

Yes, in fact it's for a subscription process, first the client choose a subscription, then he enter the name of his server and finally he must enter his contact. All works except the page for the contact.

I'm not outjectiing as "conts", "conts" is here because DataModelSelection must be attach to a Datamode, and I have two Datamodel. Otherwise, I deleted the DataModelSelection annotation and I have the same problem.

I thought @DataModelSelection doesn't need to have @Out. However I added :
anonymous wrote :
| @DataModelSelection("conts")
| @In (required = false) @Out(required = false)
| Contact contactel = new Contact();
|
And I have the same Exception.

[jboss-user] [JBoss Seam] - Re: @DataModelSelection and ClassCastException
I begin to see that i've done all that stuff in a pretty wrong way.
The factory on "lines" returns what it is used by JSF to display the lines. The
DataModel were not used to outject lines, or used in a wrong way.
I changed a bit my code and get rid of the factory.
Now, the Datamodel is well outjected, and the DataModelSelection is well
injected.
I've got a little problem, however. When I click on the line to select it (an
with the actionMethod selectline()), it would normally send me to
another page, displaying another list.
But the page stays the same, and i have no exception sent.
I show you my new code :
pages.xml :
|
|
|
|
|
|
|
|
LineManager.java :
| @Stateful
| @Name("LineManager")
| @Scope(SESSION)
| public class LineManager implements LineManagerLocal, Serializable {
|
| @In
| private EntityManager em;
|
| @DataModel("lines")
| List lines;
|
|
|
| @DataModelSelection("lines")
| private OrderLine currentOrderLine;
|
|
| @Out
| private Order myOrder;
|
|public List findlines(){
|lines=myOrder.getOrderLines();
|return lines;
| }
| @Factory(value="servs",scope=SESSION)
|public List searchServers(){
|return currentOrderLine.getServers();
| }
| @Begin(join=true)
| public void viewParameters(Order order){
| myOrder=em.merge(order);
| System.out.println("on rentre dans le line manager");
| findlines();
| }
| public List getLines(){
| return lines ;
| }
| @Begin(join=true)
| public void selectLine(Long id){
| //currentOrderLine=em.find(OrderLine.class,id);
| }
| public OrderLine getCurrentOrderLine() {
| return currentOrderLine;
|
| }
| public void setCurrentOrderLine(OrderLine currentOrderLine) {
| this.currentOrderLine = currentOrderLine;
| }
| @Remove @Destroy
| public void destroy(){
| }
| public Order getMyOrder() {
| return myOrder;
| }
| public void setMyOrder(Order myOrder) {
| this.myOrder = myOrder;
| }
|
| }
|
the code is a bit messy, since i made several tests. i'll make it up later,
when i find a solution to my problem.
Thanks to those who read that

[jboss-user] [JBoss Seam] - Re: @DataModelSelection and ClassCastException
thanks for your reply... After some check of my .ear, there's no duplicate import of hibernate... To make some stuff working, I had to add these jars to the glassfish lib directory: hibernate-all.jar thirdparty-all.jar jboss-archive-browsing.jar In my ear and my war, all the jars i have are : EAR : commons-beanutils-1.7.0.jar commons-collections-3.1.jar commons-digester-1.6.jar el-api.jar el-ri.jar jboss-seam-debug.jar jboss-seam.jar jsf-facelets.jar WAR (under WEB-INF/lib): ajax4jsf-1.1.1.jar jboss-seam-ui.jar oscache-2.3.2.jar richfaces-3.0.1.jar That's a bit weird, because the page before the one which raise the exception contains a DataModel, and it works just fine... All i have to do is to display in a first page a list of orders you can click on, then display the orderlines relatives to this order and when a user clicks on a orderline, he may see the items that are relative to it. It crashes when the user clicks on the orderline...

[jboss-user] [JBoss Seam] - @DataModelSelection and ClassCastException
Hello everybody...
I'm stuck for a couple of days with an error that makes me becoming crazy !!!
I have an .xhtml page (i work with facelets) which code is :
|
|
| #{messages['Line']}
|
|
|
|
| #{messages['Product']}
| #{line.productId.prodName}
|
|
|
My LineManager is coded as below:
| @Stateful
| @Name("LineManager")
| @Scope(SESSION)
| public class LineManager implements LineManagerLocal, Serializable {
|
| @In
| private EntityManager em;
|
| @DataModel("lines")
| List lines;
| @DataModelSelection("lines")
| private OrderLine currentOrderLine;
|
|
| @Out
| private Order myOrder;
|
|@Factory(value="lines",scope=SESSION)
|public List findlines(){
|
|return myOrder.getOrderLines();
|
| }
|
| @Factory(value="servs",scope=SESSION)
|public List searchServers(){
|
|return currentOrderLine.getServers();
|
| }
|
| @Begin(join=true)
| public void viewParameters(Order order){
| myOrder=em.merge(order);
| System.out.println("on rentre dans le line manager");
|}
|
| public List getLines(){
| return lines ;
| }
|
| @Begin(nested=true)
| public void selectLine(Long id){
| currentOrderLine=em.find(OrderLine.class,id);
| }
|
|
| public OrderLine getCurrentOrderLine() {
| return currentOrderLine;
|
| }
|
|
| public void setCurrentOrderLine(OrderLine currentOrderLine) {
| this.currentOrderLine = currentOrderLine;
| }
|
|
| @Remove @Destroy
| public void destroy(){
| }
|
| public Order getMyOrder() {
| return myOrder;
| }
|
| public void setMyOrder(Order myOrder) {
| this.myOrder = myOrder;
| }
| }
|
When I click on an OrderLine on the page, i get an exception
I show you the StackTrace :

[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - MultipleDataSelection and problem with merge
Hi everybody !
I currently develop an enterprise application able to manage a client's
account(he could see his orders, line orders and product in assocation with
those lines). I use netbeans, glassfish, seam and hibernate. I want to post
many datalist with link. I use Conversation and Session for that. I want to
know if it possible to use many DataModeleSelection.
Otherwise theirs is a problem with my ServerManger :
first page : login
second : list of orders
third : list of lines
forth : list of server concerned by the lines
|
| Code of my forth page
| Stateful
| @Name("ServerManager")
|
| public class ServerManager implements ServerManagerLocal
| {
|
|
| @In
| private EntityManager em;
|
| @DataModel
| @In(required=false) @Out(required=false)
| List servs;
|
|
| @DataModelSelection
| @Out(required=false)
| private Server currentServer;
|
|
| private OrderLine myOrderLine;
|
|
| @Factory(value="servs",scope=CONVERSATION)
| public void searchServers (){
|
|
| servs = myOrderLine.getServers();
|
|
| }
|
|
| @Begin(join=true)
| public void viewParameters(OrderLine orderLine){
| System.out.println("on rentre dans le server manager");
| myOrderLine=em.merge(orderLine);
|
|
| }
|
|
|
|
|
| @Remove @Destroy
| public void destroy(){
| }
|
| public List getServs() {
| return servs;
| }
|
|
|
| public Server getCurrentServer() {
| return currentServer;
| }
|
| public void setCurrentServer(Server currentServer) {
| this.currentServer = currentServer;
| }
|
| public OrderLine getMyOrderLine() {
| return myOrderLine;
| }
|
| public void setMyOrderLine(OrderLine myOrderLine) {
| this.myOrderLine = myOrderLine;
| }
|
|
| }
