Seam remote not working when using @Version

[cash1981]

I have a very weird behaviour going on. I have an entity that has a

@Version
public Integer getVersion() {
    return version;
}

And a webremote method that is executed by this javascript call:

Seam.Component.getInstance("applicationProcessAdmin").setDisabled(id,!checked);

However. The javascript is triggered from onclick on a checkbox. This call is never executed as long as the @Version is present. But if I remove the @Version, then suddenly it is executed. Any ideas?

The class with webremote is this:

@Name("applicationProcessAdmin")
@Scope(ScopeType.EVENT)
@AutoCreate
public class ApplicationProcessAdmin implements Serializable {

     private static final long serialVersionUID = -5671816373739928344L;
     
     @In
     private EntityManager entityManager;
     
     @Transactional
     @WebRemote
     @Restrict("#{s:hasRole('sysadmin')}")
     public void setDisabled(Long id,boolean flag) {
          ApplicationProcess ap = entityManager.find(ApplicationProcess.class, id);
          if (ap != null) {
               ap.setDisabled(flag);
               entityManager.flush();
          }
     }
}
