Re: [Wicket-develop] Hard to trace StackOverflowException - Wicket 1.1

[Riyad Kalla]

Juergen, I just got the error again after quite a few runs with plenty of records in the DB. I appreciate your offer but let me bang on it a little more on my end. I thought it might be Spring so I went through and pulled Spring out of my project completely and will see if the error magically stops. I don't want to waste anyones time. If I find something I'll send you something more concrete. Best, Riyad Juergen Donnerstag wrote: Are you sure it is not pageDAO.getPages() which creates the stack overflow?

I did a search in both users and dev lists and found this post: http://sourceforge.net/mailarchive/message.php?msg_id=11223256 Which sounds similar to what I'm seeing, although the page it's dying on isn't using any custom models just a ListView. Java code below: --------------------- public ManageContentPage(PageParameters pageParameters) { PageDAO pageDAO = (PageDAO)WebApplicationContextUtils.getWebApplicationContext(getWebRequestCycle().getWebSession().getHttpSession().getServletContext()).getBean("pageDAO"); add(new Label("title", "Manage Pages")); add(new Label("header", "Manage Pages")); add(new ListView("pageList", pageDAO.getPages()) { private static final long serialVersionUID = 1L; @Override protected void populateItem(ListItem listItem) { PageDTO page = (PageDTO)listItem.getModelObject(); System.out.println("Page: " + page); listItem.add(new Label("id", page.getId().toString())); listItem.add(new Label("name", page.getName())); listItem.add(new Label("summary", page.getContent().substring(0, 64))); listItem.add(removeLink("removeButton", listItem)); } }); } --------------------- HTML page below: --------------------- <tbody> <tr wicket:id="pageList"> <td wicket:id="id">ID</td> <td wicket:id="name">NAME</td> <td wicket:id="summary">SUMMARY</td> <td><button wicket:id="removeButton">Remove</button></td> </tr> </tbody> --------------------- The strange part is that when the DB is empty, no page records, I get the endless stack trace and overflow above. But if I just add one record, viola, it works fine. Can someone point out what checks I am suppose to implement that I missed and why this code is totally blowing instead of just displaying an empty table with no rows?
