Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
Thanks for all the hints so far, they are really helpful but ;) Well, I don't want to have busy indicators on different components, I'm looking for a way to display status messages (like eg with jGrowl) during the long-running process (triggered by AjaxButton). I guess the only way to achieve this is with a solution as stated by Nishant (involving some kind of JS polling) ... -Tom Am 09.04.2010 08:48, schrieb Tomasz Dziurko: You should check visural-wicket project (http://code.google.com/p/visural-wicket/) and live demo on http://visural-wicket-examples.appspot.com/app/ .

Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
The IAjaxIndicatorAware interface fits perfectly with your need. All you have
do, is:
- create a DOM element which looks like jGrowl with 'loading' message and
assign it an id (ex: id=ajaxIndicator)
- your webPage should implement IAjaxIndicatorAware interface:
public class MyWebPage extends WebPage implements IAjaxIndicatorAware {
//...
@Override
public String getAjaxIndicatorMarkupId() {
return ajaxIndicator;
}
//...
}
That's all. Now ajaxIndicator DOM element to appear when ajax call will
start and will disappear when it will complete.
Hope this was helpful.

Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
Ok, but this is *not* what I want to achieve, beggin' your pardon ;-) The first messages should not display when starting the operation, but when a certain sub-task is finished.

Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
Oh, I see... I got you wrong initially. Indeed, in this case.. the best solution is polling and upon subtask completion - output a jgrowl notification script.

Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
Hi Tom, What I do, for instance, when exporting files to PDF, Excel, etc, is start the process on a background thread, block the screen so that users can only wait or stop the process, and use an AJAX timer to get back to the server every few seconds to monitor the progress and display it as progress-bar. This seems to work fine for me but might not be the most efficient solution... I can give you more details if you want.

Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
Ok, thanks for the hint, but the operations I make usually only take up to ~1min, so I guess this won't be an issue in my case. But you are right, one has to assure that the polling will stop upon completion of the background task. -Tom On 09.04.2010 at 10:28, Tim L Casey wrote: You have to watch session expiration.

Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
Hi Tom, Take a look at [1]...[4]. There I'm creating a thread each time the long running process is launched but maybe it would be more correct to use a thread pool or use scheduler like quartz for this task. Feel free to use/change the code there as it best suits your needs.

I fear not. As far as I understand, getAjaxCallDecorator() decorates the
javascript with a custom script, which is executed immediately upon hitting the
button. What I want to achieve is displaying some status messaged during the
progress of my long-term operation ...

Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
I think you may look into this package
org.apache.wicket.extensions.ajax.markup.html.form.upload where upload
progress-bar is implemented. You may do something like this.
So, probably it sets a resource in session, Java part regularly updates the
string resource. And JS keeps on polling this resource by using the URL to
the resource provided to JS initializer and renders on UI. Anyone can
correct me, if I am wrong.
Just a suggestion. I am naive to Wicket.

Re: How to give feedback in long-running operation within AjaxButton.onSubmit()?
The most simple way is to implement IAjaxIndicatorAware interface on the
component wish to display the indicator. For instance, if your page
implements this interface, you will have a generic indicator for all ajax
requests inside your page. Also, you can be more specific by implementing
this interface only on a panel or a form... depends on your use-case.
