Problems migrate from Seam3 to DeltaSpike - seam3

Question

I'm just testing to migrate from Seam3 to DeltaSpike, everything is ok if there is only one EntityManager in a bean, but there will be a error if add other EntityManager(other datasource):
JBAS010152: APPLICATION ERROR: transaction still active in request with status 0
the error project:
https://github.com/yuanqixun/hellodeltaspike
run this project environment:
wildfly 8.2.0.Final
H2 datasource
MySql datasource
The EntityManagerProducer code:
#ApplicationScoped
public class EntityManagerProducer {
#PersistenceUnit(unitName = "hellodeltaspike")
EntityManagerFactory emf;
#PersistenceUnit(unitName = "hellodeltaspike2")
EntityManagerFactory mysqlemf;
#Produces
#ConversationScoped
EntityManager createEntityManager(){
return this.emf.createEntityManager();
}
#Produces
#MySqlEm
#ConversationScoped
EntityManager createMysqlEntityManager(){
return this.mysqlemf.createEntityManager();
}
}
The Action code:
#ConversationScoped
#Named
public class PersonAction implements Serializable{
#Inject
EntityManager em;
#Inject
#MySqlEm
EntityManager mysqlEm;
Person person;
List<Person> personList;
#PostConstruct
void afterCreate(){
person = new Person();
personList = queryPersonList();
}
private List<Person> queryPersonList() {
String jql = "select o from Person o ";
List<Person> result = em.createQuery(jql,Person.class).getResultList();
if(result == null)
return new ArrayList<Person>();
return result;
}
#Transactional
public void btnDoSave(ActionEvent event){
try {
if(StringUtils.isEmpty(person.getUuid())){
em.persist(person);
}else{
em.merge(person);
}
em.flush();
String msg = "Saved:"+person.getName();
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_INFO,msg,null));
person = new Person();
personList = queryPersonList();
} catch (Exception e) {
e.printStackTrace();
FacesContext.getCurrentInstance().addMessage(null, new FacesMessage(FacesMessage.SEVERITY_ERROR, e.getMessage(), null));
}
}
...getter and setter
}
and there will be error:
ERROR [org.jboss.as.txn] (default task-6) JBAS010152: APPLICATION ERROR: transaction still active in request with status 0

Answer 1

Modify the method's annotation,add the special qualifier of the right EntityManager, so the problem will be solved. But also has another problem, how to support multiple entityManager's transaction in one method?
#Transactional(qualifier = {H2Em.class})
