終於理解了Karl所說的“If any errors occur while attempting to lazy load relationships in the view (JSP) it would be hard to present a nice error to the user”，其實更痛苦的是我自己沒辦法定位錯誤，這不，今天就領教了。我的任務列表莫名其妙的報錯了：
17:05:28 DEBUG [WorkListController] listExecutingTasks (line:118) aPageExeTasks.size()[3]
17:05:32 ERROR [DispatcherServlet] serviceWrapper (line:404) Could not complete request
17:05:32 ERROR [DispatcherServlet] org.apache.jasper.JasperException
17:05:32 ERROR [DispatcherServlet] at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:358)
17:05:32 ERROR [DispatcherServlet] at
最怕這種錯誤信息了
