Re: Ajax - render Webmarkup-Container based on Wicket Events
Update:
When setting #setAllowDefault(false), the #onevent method of the web markup
container is called, but in addition also the #on select method of sortable.
When setting #setAllowDefault(true), the #onevent method is not called at all,
only the #on select method.
It seems that setAllowDefault(false or true) does not prevent the event
bubbling to parents. What might be missing?

Hi Chris,
Yes, generally speaking, you have to cancel bubbling events to parent
elements.
For a [Ajax]Link (or any event-behavior related) you have to set the
preventDefault property to true;

Dear all, I think I've now a full working version of my usecase: in EJB/@Asynchronous mode (stateless and stateful) and in CDI using Executors.

For me, that's a very nice usecase: Imagine the user clicks on a button for a long running operation, then he continues using the site, navigate between pages etc... and is notified from time to time on the progress of the operation through websockets... I can make work either 3/ or 4/ but not both in conjunction, I get this (now famous) error: *There is no application attached to current thread EJB default* I unfortunately have to say I am not a CDI expert, and there is a lot of XxxScoped possible annotation, I tried all possible combination that would be logical IMO regarding the doc, read everything I could, but now I'm stuck...

Re: Ajax - render Webmarkup-Container based on Wicket Events
Hi Chris,
Actually what you describe is the opposite of what is supposed to happen :)
I will try to look at this... There could be several reason: the region
occupied by the markup container can be misleading for instance, or there
could be a canceling bubble conflict between registered wicket ajax event
and pure jquery ones (I would be surprised but i will double check)
Btw IIRC, the event name should be click, not onclick
new AjaxEventBehavior(click)
Furthermore, is there any reason you preferred a container over a link?
Maybe you can try with a link instead, just to be sure it is not a matter
of the region being clicked...
Last point, depending of the resulting hierarchy level of elements, maybe
STOP_IMMEDIATE should be used instead of just STOP

Re: Can i render content (css) of ContextRelativeResource to markup?
Hi,
You should use response.render(CssHeaderItem.forCSS(string)). This will
contribute it in style HTML element. With your approach it will be plain
text in the middle of the HTML.
To get the string you can use new
WebExternalResourceStream(report.css).getInputStream(),
read, convert to String, close.

Hi Chris,
Right, Sortable is processing events thought the Event Bus, that's
because
2 sortables can be connected and then, these should be able to
communicate
As you are sending the event from the Sortable, you enter the
condition:
if (event.getSource() instanceof Sortable?)
I will try to find out how I can add a check, but as Sortable is
using a
generic model object (typeof T)...
I think the correct solution/workaround would be that you change the
broadcast type to EXACT, so Sortable#onEvent will not be triggered.
Thanks best regards,
Sebastien.

Hi Sven, thanks.
The onRemove method is from the class
com.googlecode.wicket.jquery.ui.interaction.sortable.Sortable:
@Override
public void onRemove(AjaxRequestTarget target, String item) {
super.onRemove(target, item);
}
Why is the payload processed in this method, as it takes the target
as
parameter? Is there another way to render the other panel or rewrite
the
payload?

Hi,
you're using a DeleteItem as payload of the event:
send(getPage(), Broadcast.BREADTH, new DeleteItem(target));
Yet in #onRemove() you're casting the payload to a String:

Would it also be an option to remove the item from the liststring and render

Re: Ajax - render Webmarkup-Container based on Wicket Events
Hi Chris,
Actually jquery ui's selectable provides the ability to prevent their
events to be fired. The option is cancel [1]
So, as I was testing, here is the full code to manage your remove button:
CSS
style type=text/css
.sortable { list-style-type: none; margin: 0; padding: 0; width: 60%; }
.sortable li { margin: 0.3em; padding: 0.3em; font-size: 1.1em;
background-color: #fff; }
.sortable li .ui-icon { position: absolute; }
.sortable li .item { margin-left: 1.3em; }
.ui-selectable .ui-selecting { background: #FECA40; }
.ui-selectable .ui-selected { background: #F39814; color: white;
}
/style
HTML
ul wicket:id=sortable class=sortable
li wicket:id=items
span wicket:id=icon class=handle[icon]/span
div wicket:id=container
span wicket:id=item class=item[label]/span
a wicket:id=removeremove/a
/div
/li
/ul

JAVA
public MyPage extends WebPage()
{
// FeedbackPanel //
this.feedback = new JQueryFeedbackPanel(feedback);
this.add(this.feedback.setOutputMarkupId(true));
// Sortable //
final MySortable sortable = new MySortable(sortable, list, new
Options(handle, Options.asString(.handle)));
this.add(sortable);
}
class MySortable extends SortableString {
public MySortable(String id, ListString list, Options options)
{
super(id, list, options);
}
@Override
protected void onInitialize()
{
super.onInitialize();
this.add(new
SelectableBehaviorString(JQueryWidget.getSelector(this), new
Options(cancel, Options.asString(.handle))) {
private static final long serialVersionUID = 1L;

MySortable.this.onRemove(target, removedItem);
MySortable.this.info(removed + removedItem);
target.add(feedback);
target.add(MySortable.this);
}
});
}
};
}

Right, it seems that the selectable widget registers its event with a

The link's click event is just never fired, so we can forget about

not executed.

Hi Chris, Yes it works like you did but on a strict point of view, its better to notify the component its modelobject changed (and the page is also aware that a child component model has changed)...
