In Wicket 6.x it is wrongly named "setAllowDefault()".

Re: Ajax - render Webmarkup-Container based on Wicket Events

2015-02-06 Thread Chris

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 AjaxFallbackLink("link") {

@Override
public void onClick(AjaxRequestTarget target) {   
}

@Override
protected void updateAjaxAttributes(AjaxRequestAttributes 
attributes) {
super.updateAjaxAttributes(attributes);
attributes.setPreventDefault(true);
}
};

 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.

Re: Ajax - render Webmarkup-Container based on Wicket Events

2015-02-06 Thread Sebastien

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,
Sebastien

Re: Ajax - render Webmarkup-Container based on Wicket Events

2015-02-06 Thread Chris

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(ListItem 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, you probably you can use an iterator instead of the "foreach"
statement...
Thanks for letting know you solved it! :)

I have fixed it - it was because of calling the method within the for loop.

Sortable - ConcurrentModificationException

2015-02-06 Thread Chris

Hi Sebastian,

I am using the method #ListUtils.move to sort a list of domain objects as soon 
as the method #onUpdate is called within a sortable object:
In the first request, everything is fine, but in the second request I am 
receiving following error:
Root cause:

java.util.ConcurrentModificationException
 at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:901)
 at java.util.ArrayList$Itr.next(ArrayList.java:851)

Can you give me a hint why this error occurs and how to fix it?

@Override
public void onUpdate(AjaxRequestTarget target, String item, int index) {
super.onUpdate(target, item, index);
user.sortObj(item, index);

}
*
Class User:
private final List selectedItems = Lists.newArrayList();
public void sortItems(String itemName, int index) {
for (Item currentItem : selectedItems) {
  if (itemName.equals(currentItem.getName())) {
  ListUtils.move(currentItem, index, selectedItems);
  }
}
}

2015-02-06 Thread Sebastien

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.

Can i render content (css) of ContextRelativeResource to markup?

2015-02-06 Thread Per Newgro

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


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);
}


but i get

It seems that my ContextRelativeResource only provides content as byte[] ans 
StringResponse not supporting this.
Maybe i be off the track.

Thanks for your support

Re: Removing table coloumn headers in wicket pageablelistview when list is empty

2015-02-06 Thread lucast

Hi K,

If you want to hide the headers when the table is empty, you could use
 as suggested on the  wicket guide
  .

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 .

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.

Let me know if that works,

Kind regards,
Lucas
