Hello,
I had already tried with the TransactionAttribute removed. I looked closer to
the NullPointerException in the stacktrace
| Caused by: java.lang.NullPointerException
| at
org.jboss.seam.contexts.BusinessProcessContext.getNamesFromContext(BusinessProcessContext.java:1
| 15)
|
I took a dive in this Seam code:
|
| private Set<String> getNamesFromContext()
| {
| //TODO: note that this is called from Contexts.destroy(),
| // after the Seam-managed txn was committed, but
| // this implementation requires a hit to the database!
| HashSet<String> results = new HashSet<String>();
| org.jbpm.taskmgmt.exe.TaskInstance taskInstance = getTaskInstance();
| if (taskInstance==null)
| {
| ContextInstance context = getContextInstance();
| if ( context!=null )
| {
| results.addAll( context.getVariables().keySet() );
| }
| }
| else
| {
| results.addAll( taskInstance.getVariables().keySet() );
| }
| return results;
| }
|
|
Apperantly context.getVariables() is null obviously causing the
NullpointerException.
I tried to quickfix this with
|
| if ( context!=null && context.getVariables() !=null )
| {
| results.addAll( context.getVariables().keySet() );
| }
|
|
I don't know if it is a correct fix but this seemed to work for me.
Another thing that fixes the thing is actually Outjecting a variable to the
business context.
|
| @Stateless
| @Name("inklessProcessManager")
| @Interceptors(SeamInterceptor.class)
| public class InklessProcessManagerImpl implements InklessProcessManager {
|
| @Out(scope=ScopeType.BUSINESS_PROCESS, value="foo") Integer someThing;
|
| @CreateProcess(definition="inkless")
| public void startProcess() {
| someThing=new Integer(5);
| }
|
| }
|
|
So i presume this is an bug. Shall i create a JIRA issue for this.
Best regards,
Jo
