Hello again,
i found a solution for the problem (maybe).
First the concrete Exception is:
Caused by: javax.el.ELException: /client/claim_list.xhtml @16,52 value="#{testLi
| st.dataModel}": Error reading 'dataModel' on type
de.iseki.garantieext.card.Test
| List_$$_javassist_0
| at
com.sun.facelets.el.TagValueExpression.getValue(TagValueExpression.ja
| va:76)
| at javax.faces.component.UIOutput.getValue(UIOutput.java:173)
| ... 69 more
| Caused by: java.lang.IllegalStateException: EntityManager is closed
| at
org.hibernate.ejb.EntityManagerImpl.getSession(EntityManagerImpl.java
| :42)
So the reason was the closed EntityManager. My solution is to add:
| @In private EntityManager entityManager;
|
| @Override
| public EntityManager getEntityManager() {
| return entityManager;
| }
|
Do you think that it is good solution? Why is the EntityManager fetched in such
a complicated way by the EntityQuery class (by using the PersistentContext)?
