Re: Ajax - render Webmarkup-Container based on Wicket Events
Hi Sebastian,
thanks for your help. Has that the method signature recently changed? The
method #setPreventDefault is not available on the object #attributes.
Link link = new AjaxFallbackLinkString(link) {
@Override
public void onClick(AjaxRequestTarget target) {
}
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes
attributes) {
super.updateAjaxAttributes(attributes);
attributes.setPreventDefault(true);
}
};

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;
protected void updateAjaxAttributes(AjaxRequestAttributes attributes)
{
super.updateAjaxAttributes(attributes);
attributes.setPreventDefault(true); // cancel bubbling
}
Hope this helps,
Best regards,

Hi Sebastian,
I would have a follow-up question regarding the #Sortable:
Is it possible to add an AjaxLink to the item with its own behavior so
that if the user clicks on this link, then its on-click behavior should be
called instead of the #onselect method from the sortable. At the moment,
the #onselect method would be called for this link.

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

I think the correct solution/workaround would be that you change the

The onRemove method is from the class

Why is the payload processed in this method, as it takes the target as

Re: Removing table coloumn headers in wicket pageablelistview when list is empty
Hi K, If you want to hide the headers when the table is empty, you could use wicket:enclosure as suggested on the wicket guide https://wicket.apache.org/guide/guide/single.html#keepControl_9 . I have used the PagingPage from Wicket Examples (you can download it from Apache Wicket page) to illustrate this. I don't know how you check if the table is empty. I just went for dataView.getItemCount(). If you want the table with headers hidden, just call dataView.setVisible(false); And on HTML, use wicket:enclosure. Example: Note that on wicket:enclosure tag, I had to name the child it was referring to: pageable. Otherwise, it will throw an exception because wicket will not know which element you are referring to, in this case.

Can i render content (css) of ContextRelativeResource to markup?
Hi,
I like to render a PDF by my wicket page using flying-saucer. There i reference
my css file by url (link). So far everything works.
But if i switch to SSL flying-saucer breaks. Hmm.
My solution to this issue would be to include content of my css file directly
in the wicket-page used to render the pdf.
I tried to get the resource and render it in markup like this
code
MyPage.java
@Override
public void renderHead(IHeaderResponse response) {
IResource s = new SharedResourceReference(report.css).getResource();
Attributes a = new Attributes(getRequest(), getResponse());
s.respond(a);
super.renderHead(response);
}
/code
but i get

Re: Sortable - ConcurrentModificationException
Hi Chris,
Right, you probably you can use an iterator instead of the foreach
statement...
Thanks for letting know you solved it! :)
Best regards,
Sebastien.

Re: Ajax - render Webmarkup-Container based on Wicket Events
Hi Sebastian,
I would have a follow-up question regarding the #Sortable:
Is it possible to add an AjaxLink to the item with its own behavior so that if
the user clicks on this link, then its on-click behavior should be called
instead of the #onselect method from the sortable. At the moment, the #onselect
method would be called for this link.
Thanks a lot,
Chris
@Override
protected void populateItem(ListItemString item)
{
item.add(new EmptyPanel(icon).add(AttributeModifier.append(class,
ui-icon + JQueryIcon.ARROW_2_N_S)));
item.add(new Label(item, item.getModelObject()));
item.add(AttributeModifier.append(class, ui-state-default));
}

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?
br, Chris

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:
java.lang.ClassCastException: tripplanner.mycompany.DeleteItem
cannot be cast to java.lang.String

Wicket CDI and Asynchronous (and Websockets)
Dear all, In a usecase I've explained in a recent discussion [1], I would like to enhance it a little to finally obtain: 1/ An ajax button that launch 2/ 2/ A CDI injected EJB that executes an *asynchronous* time consuming operation 3/ Getting back to the wicket side to complete the ajax operation. 4/ A listener that has been provided to the EJB which, when events are fired, retrieve websockets information from the wicket Session (previously stored) and send a notification to the UI/user trough the websocket. 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... I am almost sure this is feasible, but maybe not as so easy as it seems I've prepared a concrete quickstart [2], it just need to be compiled and deployed in WidlyFly (JBoss 8), due to the websockets... I know I am asking for a real favor but I would be very thankful to the person(s) who would be able to make it work! I will leave the quickstart in my github's repo so any other user whiling to achieve the same usecase would already have a starting point... Thanks a lot in advance, Sebastien.
