How to get URLs for images with in a WebApp
Hi All, I have a use case like this which needs some help. There is folder in my web app called images. There are some images in that folder which are dynamically added. In my application, I want to list down URLs for all these images. Can any one give me some hints ? Thanks! -- Regards Andun S.L.

Link to last version of stateful page
I have a number of stateful pages with some state for each page. For example
each page has already submitted form.
How can I organize a menu with links to last versions of these stateful
pages? Should I store anywhere (may be in the session) reference to
appropriate object for each page? If I use
onClick() { setResponsePage(MyPage.class); }
than I lose the previous state of the page. I want to link to last state of
the page.

Directory Listings
Hi, I am using Wicket 1.5.3 in a WebSphere context and encountered an interesting behaviour which I dont fully understand. My application uses a /* mapping to WicketServlet and the application generally works fine. However I wonder what happens to static content (images, ) which is requested through the same path mapping? Due to the mapping I'd take it all requests go through Wicket and depending on whether the content physically exists on the disk it delivers it or processes the specified application class. Is this correct? The question arose from an interesting phenomenon with directories, respectively their listings I have a production instance running WebSphere and local development instance using Tomcat. Requests to static content always return the respective file. However the behaviour is different for directories. In the case of the production server (WebSphere) it returns the directory listing, in case of the development instance I get a Tomcat error. My initial assumption was, Wicket passes such requests back to the default handler and the listing comes from the respective server, but this does not seem to be the case as the directory listing layout I get (only a plain list with entry name) is entirely different from WebSphere's (fancier with entry dates, more formatting, ). I also tried to simply map the servlet to / only (without the wildcard) but immediately get a StringIndexOutOfBoundsException in WebXmlFile.getFilterPath() Does anyone have a clue what is going on here and whether Wicket actually returns directory listings at all?

Re: Link to last version of stateful page
Hi Junixar!
You have to give the Page Object to the new Class like:
onClick() { setResponsePage(new MyPage(Frontpage.this))}
This should help.

You can use a PageReference:
PageReference reference = page.getPageReference();
Page page = reference.getPage();

Re: Directory Listings
Thanks, so basically the /* mapping should not interfere with non-Wicket requests? In other words, static content as well as potential directory listings (respectively related error messages if disabled) will always be passed on and served by the underlying application server (be it WebSphere or Tomcat or .), correct?

Re: Directory Listings
Wicket expects the path to end in a wildcard. Note that using WicketFilter instead of WicketServlet is recommended.

Re: Thread safety of various Wicket classes?
Given that behaviors are stateless, why is it discouraged to share them? Behaviors can be stateless, but they don't need to be. You can share them between components in the same page. But sharing behaviors (or models) between pages is not possible, because each page is serialized separately.

Display Loading When Busy Navigator and DataView
Currently I have two panels. I have one panel that is handling code that is like a PagingNavigator(custom coded) And another panel that is handling the DataView. I'm currently trying to figure out the best way to show that the DataView results are pulling data from the database when they click on the PagingNavigator page. In the panel that contains the PagingNavigator I have a WebMarkupContainer that contains a loading image. That is visible and invisible depending on the situation. I would like that image to show when a user clicks on a Page in the Navigator since it will be loading results from the database and disappear when its done. I have tried creating a function in the panel that contains the PagingNavigator To allow the DataView Panel to set the visibility which doesn't seem to work. I maybe going about this wrong, but if someone has done something like this, how did you do it? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Display-Loading-When-Busy-Navigator-and-DataView-tp4661126.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
AjaxChannel usage
I would like to have my file upload requests on my site, which take much
longer than a normal request, go through a different mechanism. I'd like
the user to still be able to click around the site and work while the file
is uploading and then when it finishes, I can pop up an All Done type
dialog. AjaxChannel seems to me to be the mechanism to do this, but either
I am doing it wrong or it doesn't work as I'd expect.
My links I'm testing the concept with looks like (I'm using wicket 6.10.0):
add(new AjaxLinkVoid(slow) { @Override public void
onClick(AjaxRequestTarget target) { System.out.println(Slow Link
Clicked); try { Thread.sleep(Integer.valueOf(1)); } catch
(InterruptedException ie) {} target.appendJavaScript(alert('Done with slow
running request');); System.out.println(Done Processing Slow Link.); }
@Override protected void updateAjaxAttributes(AjaxRequestAttributes
attributes) { super.updateAjaxAttributes(attributes);
attributes.setChannel(new AjaxChannel(upl, AjaxChannel.Type.QUEUE)); }
}); add(new AjaxLinkVoid(fast) { @Override public void
onClick(AjaxRequestTarget target) { System.out.println(Fast Link
Clicked); target.appendJavaScript(alert('Done with fast running
request');); System.out.println(Done Processing Fast Link.); } });
I would expect that if I click Slow, then click Fast that the fast would
return to the user before the slow, but that's not happening.
I can attach a quickstart and create an issue in JIRA if that is the route
to go if I am doing it right. If I'm doing it wrong, can someone let me
know how I can accomplish what I'm looking to do?
Thanks,
Steve
