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 AjaxLink("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 AjaxLink("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
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

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.

Re: Link to last version of stateful page
You can use a PageReference:
PageReference reference = page.getPageReference();
Page page = reference.getPage();

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.

Re: How to get URLs for images with in a WebApp
Hi,
It was a issue with my IDE integration. I am running the webapp via Tomcat
in IntellijIDEA. It runs the wicket application in the bin folder of
Tomcat. Thus some issue arises. Then I tried manually with Tomcat. Then it
works.
Thanks!

Re: How to get URLs for images with in a WebApp
Hi Maxim,
I tried that method. In my web app I can access a image using this url,
http://localhost:8080/ClipArts/images.jpeg
Then I tried,
((WebApplication)
WebApplication.get()).getServletContext().getRealPath("ClipArts")
((WebApplication)
WebApplication.get()).getServletContext().getRealPath("ClipArts/images.jpeg")
((WebApplication)
WebApplication.get()).getServletContext().getRealPath("/ClipArts/images.jpeg")
Each of these cases it return null. Also I am suing this code inside a
Constructor of a Custom behavior. What can be the reason?
