我有一个包含两个标签的标签视图，第一个标签包含一个数据表，第二个标签包含谷歌地图。问题是，一旦我从第一个标签移动到第二个标签，就不会加载内容（不显示地图）。我正在使用primefaces 4。
这是我的代码： 这是包含数据表的第一个选项卡
<h:form>

这是包含Google地图的第二个标签：

</div><!-- /.box-tools -->

</div><!-- /.box-body -->
</div><!-- /.box -->
</div>
</div>
</h:form>
</p:tab>
</p:tabView>
onTabChanged方法包含一条消息：
public void onTabChanged(TabChangeEvent e){
System.out.println("Success,tab changed");
FacesContext.getCurrentInstance().addMessage("Message5", new FacesMessage("Tab With Index :: "+e.getTab().getTitle()+" Is Changed"));
}
如果有人能帮助我，我将感激不尽
