在网上找了半天，连一个中文的解决方案都没有，还是参考的OTN Community的一个帖子（https://forums.oracle.com/thread/2389847?tstart=525）
引用：Open your .jspx file in the editor. Select the graph component. Click on the Bindings tab at the bottom.
You should see a binding between a graph component (under Bindings) to an Iterator (Executable) to
a Data Control element. Click on the Iterator,and under Advanced,set the CacheResults to false and rerun the application.
英文好的应该能看懂，不过我没看懂，经过询问之后解决方案如下：
打开.jspx文件，选择底部的bindings标签，如图
然后，找到Executable下的 EmployeesView3Itereator（因为拖放graph的时候拖拽的EmployeesView3），再如图
找Property Inspector，看这里哈，EmployeesView3Iterator - Property Inspector，有一个Advanced，Advanced下面有个CacheResults，值选择false， OK！ 这样就解决了 ，再次启动看看。
