Subject AjaxChannel usage
Date Wed, 28 Aug 2013 21:53:10 GMT
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<Void>("slow") { @Override public void
onClick(AjaxRequestTarget target) { System.out.println("Slow Link
Clicked...."); try { Thread.sleep(Integer.valueOf("10000")); } 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<Void>("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?
