Re: How to invalidate session after panel replacement?
Thanks Ernesto.
It is doable without JavaScript:
WebRequestCycle requestCycle = (WebRequestCycle) RequestCycle.get();
WebRequest webRequest = (WebRequest) requestCycle.getRequest();
HttpServletRequest httpServletRequest =
webRequest.getHttpServletRequest();
httpServletRequest.getSession().setMaxInactiveInterval(5);
It is not perfect, and I thought that Wicket, depending so heavily on
the session, would provide a means to destroy it after use.

Bernard

Re: Saving an Excel file using WebResource
This worked:
@Override
public IResourceStream getResourceStream() {
HSSFWorkbook workbook = getExcelWorkbook(new HSSFWorkbook());
byte[] bai = workbook.getBytes();
ByteArrayResource bar = new ByteArrayResource("application/vnd.ms-excel",
bai);
return bar.getResourceStream();
}

Re: wicket-velocity velocimacro.library
Funny, just yesterday I was trying to get wicket-velocity to work. So, I downloaded the velocity source and went code spelunking. The singleton, org.apache.velocity.app,Velocity, has a method setProperty which, if set before the init method is called, allows you to override the velocimacro.library property. The Velocity.init method is called in org.apache.wicket.velocity.Initializer which, in turn, is created and call from Application.scala (the wicket.properties file contains: initializer=org.apache.wicket.velocity.Initializer which is read by Application.scala). Now, Application.scala does this work from the call to its initApplication method. So, if you set the Velocity property before calling Application.initApplication it should work. I said, should, since this is not what I did; I simply commented out the line velocimacro.library = VM_global_library.vm in the velocity.properties file. An alternative is to find the VM_global_library.vm file in the Velocity distribution (under test/templates) and put it where it can be loaded. Again, I did not do this.

multi-window support, pagestores and wicket 1.5
Hi folks, I know that there has been a lot of written about pagestores and multi-window support in wicket 1.5, but i have several other questions: 1. Is multi-window supported for non-versioned pages? If page is versioned everything works ok, but i always get StalePageExceptions when i use multiple windows/tabs with non-versioned pages. I think that StalePageException is useful in some cases when you wanna be sure that user has same page in all windows, but in older versions of wicket it was possible to have non versioned pages and multi-window support together (e.g. we have an application written in wicket 1.2.6 that uses non-versioned pages in multiple windows) 2. How page stores work in clustered environment? In older versions of wicket we used pagemaps stored in HttpSession. When one node in cluster refuses to handle request, it was successfully handled by another nod, because HttpSession was replicated to another node. We have used non-versioned pages (no back button support needed) and in one pagemap there was max 5 pages. Wicket provided this functionality out-of-box. 3. How to achieve this in wicket 1.5? I have found PersistentPageManager which uses IPageStore to store pages. Pages are stored on disk by default, but there is also thread safe SerializedPagesCache with SoftReferences. Theres no out-of-box solution to store pages in HttpSession. I have also found file page-management.txt in org.apache.wicket.page package. It contains proposal of other pagamanagers and multi-window support for non-versioned pages. The proposal contains classes PersistentPageManager with DiskPageStore and SecondLevelCacheSessionStore for versioned pages SessionManager for holding non versioned pages in HttpSession. 4. Can we expect that this proposal will be implemented in wicket 1.5 final version? Thanks for your replies.

Yes, please. Create a ticket with a quickstart.

StalePageException and AJAX possible bug
Hi, I have encountered a problem when using not versioned page with AJAX in multiple tabs/windows . Suppose I have ajax link which changes its model in non versioned page. I open the same page in new tab/window and click on the link. When i click the link in the first tab/window i get javascript error Wicket.Ajax: Wicket.Ajax.Call.failure: Error while parsing response: Could not find root element This occurs because theres a hole page rendered in response (ajax-response element is missing) Should i create JIRA issue or is this a known bug?
