Hy everybody,

I have a problem with my application. I'm getting this error, but I appear randomly and in different point of my code. Many times it works on that line of code, sometime time not...
I'm trying to fix it for some days ago...but I didn't have any chance to find where is the problem. Maybe there is a problem of configuration... for persistence.xml. ..I realy can't image where is it.
I'm using jboss 7, ejb 3.0, hibernate 3(JPA) and spring.
Here is some lines of my code :

OrganizationStructureBean.java is a my Ebj bean.

{
@EJB
EntityPositionDAOLocal entityPositionDAO;

entityPositions =
new HashSet<EntityPosition>(
entityPositionDAO.getAllActiveByEntityBean(idEntity));
if (CollectionUtils.isNotEmpty(entityPositions)) {
// check if it has positon and build second array of info
for (EntityPosition epObj : entityPositions) {

EntityBean entityBean = epObj.getEntityBean();

Position position = epObj.getPosition();
String posCode = "";
String posLangName = "";
if (position != null) {
posCode = position.getCode();
...}

}
Please, help me.
