> When creating a JBPM Process Instance with @CreateProcess but no Attributes are outjected to the BusinessProcessContext a NullPointerException will be thrown at you. Example Code:
> @Stateless
> @Name("inklessProcessManager")
> public class InklessProcessManagerImpl implements InklessProcessManager {
> 	@CreateProcess(definition="inkless")
> 	@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
> 	public void startProcess() {
> 	}
> }
> Stacktrace:
> Caused by: java.lang.NullPointerException
> 	at org.jboss.seam.contexts.BusinessProcessContext.getNamesFromContext(BusinessProcessContext.java:1
> 15)
> 	at org.jboss.seam.contexts.BusinessProcessContext.getNames(BusinessProcessContext.java:97)
> 	at org.jboss.seam.contexts.Contexts.destroy(Contexts.java:241)
> 	at org.jboss.seam.contexts.Contexts.flushAndDestroyContexts(Contexts.java:356)
> Code that works:
> @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);
> 	}
> }
