Hi everybody,
I have a problem upgrading from version 1.1.6 to 1.2.1GA.
There is a part of the application that works perfectly with 1.1.6 and gives errors with
1.2.1GA.
I have the following bean (I deleted from .java and .xhtml files all the unnecessary code
and I left only what appears in this post, and still I have the same problem):
| @Name("machineManager")
| @Scope(ScopeType.CONVERSATION)
| @Transactional
| public class MachineManager extends ManagerBase {
| @Valid
| private Machine machine;
|
| @DataModel
| private List<KValue> mkValues;
|
|
| @Begin(id="#{machineManager.conversationId}", join=true,
flushMode=FlushModeType.MANUAL)
| @Transactional
| public String start() {
| System.out.println(this + "->start-------->" +
Contexts.getConversationContext());
| if(entityId > 0 && machine == null) {
| machine = getInstance();
| }
| else if(machine == null){
| machine = create();
| }
| return "";
| }
|
| public String getConversationId() {
| return "mch_" + entityId;
| }
|
|
|
| public Machine getInstance() {
| if(machine == null) {
| machine = entityManager.find(Machine.class, entityId);
| }
| return machine;
| }
|
|
| @Factory("mkValues")
| public void getMkValues() {
| if(mkValues == null) {
| mkValues = getInstance().getKValues();
| }
| }
|
|
| private Machine create() {
| Machine machine = new Machine();
| machine.setCompany(loginInfo.getCompany());
| machine.setPlant(loginInfo.getPlant());
| return machine;
| }
|
| }
|
In the machine.page.xml I have
| <page action="#{machineManager.start}">
| <param name="entityId" value="#{machineManager.entityId}"
/>
| </page>
|
In the /protected/machine/machine.xhtml I have the following code
| <ui:define name="body">
| <h:inputText value="#{machineManager.instance.code}"/>
| <s:link
value="Kappas" view="/protected/machine/machine_kappas.xhtml"
propagation="join" />
| </ui:define>
|
where the s:link links to the following page (machine_kappas.xhtml) that contains a
dataTable backed by the mkValues datamodel:
| <ui:define name="body">
| <h:form>
| <h:dataTable value="#{mkValues}"
| var="kappa">
| <h:column>
| #{kappa.name}
| </h:column>
| </h:dataTable>
|
| </h:form>
| </ui:define>
|
When I click on the link in machine.xhtml to go to machine_kappas.xhtml, I get the
following exception:
GRAVE: Error Rendering View[/protected/machine/machine_kappas.xhtml]
java.lang.NullPointerException

What happens is that when I go to the machine_kappas.xhtml page the conversation does not
contain anymore the data it was initialized with: machine is null, entityId is 0.... and
so on. After the error, if I try to reload the machine.xhtml page from the link that
should call the start method, I get the same error, the start method is not called anymore
and the conversation is no more available.
It looks very strange, because I do not think I did anything strange and with 1.1.6 all is
working smoothly.
Any idea about what is going on ?
Many thanks as usual.
Ciao Francesco
