Question

我正在使用Mojarra，PF 3.5 SNAPSHOT，Tomcat 7.0.32并尝试在其他客户端进行更改时自行进行数据表更新。我也在使用CDF bean和MyCODI，@ ViewAccessScoped。

当我使用3.4时，行内编辑（而不是单元格内编辑）和标准@ConversationScoped它正在工作。

豆：

      public void update(Object object) {
    if (!getEm().getTransaction().isActive()) {
        getEm().getTransaction().begin();
    }
    try {
        get().merge(object);

    } catch (PersistenceException e) {
        if (ExceptionUtil.is(e, ConstraintViolationException.class) || ExceptionUtil.is(e, RollbackException.class)) {
