I wrote a simple pageflow using jPDL. It has a two pages: one start-page node
that transitions to another page node.
The bean class looks like:
| @Stateful
| @Name("viewReports")
| @Conversational(ifNotBegunOutcome="home")
| @Interceptors(SeamInterceptor.class)
| @Scope(ScopeType.CONVERSATION)
| public class ViewReportsAction implements ViewReports {
| @PersistenceContext(type = PersistenceContextType.EXTENDED)
| EntityManager entityManager;
|
| @Create @Begin(join=true,pageflow="viewReports-pageflow")
| public void begin() {
| }
|
| public void viewReport() { ... }
|
| @End
| public void end() {
| }
|
| @Remove @Destroy
| public void destroy() {
| logger.info( "Destroy method called." );
| }
| }
|
In addition, my "viewReports" bean has an EntityManager using
@PersistenceContext(type=EXTENDED).
When I test this out, the "begin()" method is called, but then it results in
this stacktrace (abbreviated):
| SEVERE: Error Rendering View[/viewReports.xhtml]

It seems that the component was removed immediately after it was created.
Further down the stacktrace, it complains about
| 2006-05-26 10:21:23,316 ERROR [STDERR] org.hibernate.TransactionException:

Here are some of the other configuration settings:
| <context-param>

<param-name>org.jboss.seam.core.jbpm.pageflowDefinitions</param-name>
| <param-value>reports-nav.jpdl.xml</param-value>
| </context-param>

I've been debugging this problem for the last day. It doesn't seem to be too
complicated a scenario, since there is only two states/pages.
Does anyone have any insight on why this is happening?
I am using JBoss Seam 1.0.0 CR2 with JBoss 4.0.4.CR2. I believe it is Hibernate
3.1.1?
