Tobias sent me a quickstart app.

TestPage is stateless and thus never stored in the storages.
Just add setStatelessHint(false) to its constructor and the problem
disappears.

 not generating it inside it's context?
  And where do you need/use the final generated URL? I guess inside the

Oh NO

This completely solved my problem

Now all is working like expected...

Now I'm able to render a Javascript-Callback-Function with a custom
EL-Function within a JSP and if I use this Javascript-Function in a link
for example I can update component on the current page. Example:

wicket:jsp file=/TestPage.jsp /

In JSP:

a href=# onClick=${wicket:createAjaxCallback()}Update/a

In WebPage with setStatelassHint(false):

@Override
public void onEvent(IEvent? event) {
if (event.getPayload() instanceof GlobalAjaxEvent) {
AjaxRequestTarget ajaxRequestTarget =
((GlobalAjaxEvent)event.getPayload()).getAjaxRequestTarget();
label.setDefaultModelObject(updated panel);
ajaxRequestTarget.add(label);
}
 }

and in Application's init method:

GlobalAjaxResource.configure(this);

I will try out to make this call also available to forms or other html
elements within jsps and then I'm going to publish it on wicketstuff minis.
:-)

Thanks a lot for all the help and time you spend by solving this problem!

Re: Global Ajax Event Handler

2014-09-09 Thread Tobias Soloschenko 
I want to have the possibility to add a listener at application Level like in 
this pseudo code 

Server side
getGlobalAjaxBehaviors().add(myid,new GlobalAjaxBehavior(){

 public void respond(GlobalRequest request){
 // here the Event is received 
// request.getArguments();
 // request.replace(...)
}
}

Client side
Wicket.Ajax.get({id,somearguments});

This would allow me to send ajax request from any applications rendered at the 
Same page but which aren't able to access the wicket component structure. But 
within the event I would like to add and replace components based on the given 
args. Maybe application is Not the right place - Page would also be ok by 
adding the page class to the listener instead an id and the page class itself 
could implement an Interface for handling the event.

Re: Global Ajax Event Handler

2014-09-09 Thread Martin Grigorov 
I am still confused :-)
You used class names which are not available in Wicket 6.17.0 so I cannot
map them to any functionality that is possible with local behavior.

My guess is that you ask
about org.apache.wicket.ajax.AjaxRequestTarget.IListener#updateAjaxAttributes()
You can register custom listener like this:
https://github.com/apache/wicket/blob/master/wicket-core/src/test/java/org/apache/wicket/ajax/GlobalUpdateAjaxAttributesTest.java#L40

This way you have a global (server side, application-wide) way to
manipulate the AjaxRequestAttributes for *all* Ajax behaviors/components.

Does this solve the problem ?
If NO then please explain how you would do it the local way.

RE: Global Ajax Event Handler

2014-09-09 Thread Richter, Marvin 
What you are looking for is the Wicket Event mechanism.

This allows you to send a broadcast to a specified Component (e.g. the current 
page) and a payload (e.g. your custom event type which contains information).

In the Components which should react on the event you override the method 
onEvent, check if the event is of your type and if so, do with the event 
payload whatever you want.

Check out 
http://www.wicket-library.com/wicket-examples/events/wicket/bookmarkable/org.apache.wicket.examples.source.SourcesPage?1SourcesPage_class=org.apache.wicket.examples.events.DecoupledAjaxUpdatePage
 for a good example.

Marvin

Re: Global Ajax Event Handler

2014-09-09 Thread Martin Grigorov 
I've re-read the message and I think I got it.
What you really need is a mounted resource
(WebApplication#mountResource(someResourceReference))
To get a url to it use: theUrl = requestCycle.urlFor(sameResRef,
parametersWithPageId)
Wicket.Ajax.get({u: theUrl, ...})
In IResource#respond() you can create AjaxRequestTarget with:

Page page = session.getPageManager().get(parameters.get(pageId))
target = webApplication.newAjaxRequestTarget(page)
requestCycle.scheduleRequestHandlerAfterCurrent(target);
page.send(page, Broadcast.BREADTH, new SomeEvent(target))

in SomeComponent#onEvent() use someEvent.getTarget().add(this) to add the
component when SomeEvent is broadcasted

Hi,

the example shows up event bubbling which is not what I mean. 

Thanks anyway :-)

Kind regards

 What you are looking for is the Wicket Event mechanism.
 
 This allows you to send a broadcast to a specified Component (e.g. the 
 current page) and a payload (e.g. your custom event type which contains 
 information).
 
 In the Components which should react on the event you override the method 
 onEvent, check if the event is of your type and if so, do with the event 
 payload whatever you want.

 is there a way to register a global ajax event handler within Wicket? For

 What you really need is a mounted resource
 (WebApplication#mountResource(someResourceReference))
 To get a url to it use: theUrl = requestCycle.urlFor(sameResRef,
 parametersWithPageId)
 Wicket.Ajax.get({u: theUrl, ...})
 In IResource#respond() you can create AjaxRequestTarget with:
 
 Page page = session.getPageManager().get(parameters.get(pageId))
 target = webApplication.newAjaxRequestTarget(page)
 requestCycle.scheduleRequestHandlerAfterCurrent(target);
 page.send(page, Broadcast.BREADTH, new SomeEvent(target))
 
 in SomeComponent#onEvent() use someEvent.getTarget().add(this) to add the
 component when SomeEvent is broadcasted

Pass the pageId as a query string parameter.

PageParameters params = new PageParameters();
params.set(pageId, getPage().getPageId());
theUrlToTheReference = requestCycle.urlFor(yourResRef, params);

Then in the IResource (better extend AbstractResource) just read it from
the request parameters.

Storing the pageId in the session is not OK because the user may open two
different pages in separate tabs/windows and this will break.

I didn't modified the Session - the pageId is stored in

Hi all,
   
is there a way to register a global ajax event handler

   For normal there is the AbstractDefaultAjaxBehavior which is

to a

Is there a way to do this on application level so that Im

RE: Global Ajax Event Handler

2014-09-09 Thread Richter, Marvin 
That definitely sounds like a really odd use case or am I wrong?

Do you really want to generate the URL outside from the Wicket context?
I mean this is something which is heavily tied to wicket anyway so why not 
generating it inside it's context?
And where do you need/use the final generated URL? I guess inside the Wicket 
context ... 

Maybe you should rethinking your use case, I bet the problem you're trying to 
solve can be solved much, much easier!

Anyway .. wish you luck ;)

 Session#pageId is a counter that is used to give an id to the next
 created
 page.
 It is not the id of the currently used page!
 
 You will need to provide the pageId somehow to the class that 
 generates
 the
 url.

 The method getPage() is not available at the place where I'm

 the
 link - I'm not within a component and I try to get the page by

 the session. :-)
 
 I didn't modified the Session - the pageId is stored in 
 org.apache.wicket.Session.pageId which is an AtomicInteger

 Pass the pageId as a query string parameter.
 
 PageParameters params = new PageParameters(); params.set(pageId, 
 getPage().getPageId()); theUrlToTheReference = 
 requestCycle.urlFor(yourResRef, params);
 
 Then in the IResource (better extend AbstractResource) just read 
 it
 from
 the request parameters.
 
 Storing the pageId in the session is not OK because the user may 
 open
 two
 different pages in separate tabs/windows and this will break.

 Thanks again for the fast answer. My code now looks this way:
 
   Field declaredField =
 WebSession.get().getClass().getSuperclass()
   .getDeclaredField(pageId);
 
   declaredField.setAccessible(true);
   AtomicInteger i = (AtomicInteger) 
 declaredField.get(WebSession.get());
   Page page = (Page) WebSession.get().getPageManager()
   .getPage(i.get());
 
   AjaxRequestTarget newAjaxRequestTarget =
 ((WebApplication)
 Application.get())
   .newAjaxRequestTarget(page);
 
   RequestCycle.get().scheduleRequestHandlerAfterCurrent(
   newAjaxRequestTarget);
 
 I dont know how to get the current pageId but from the Session. 
 The
 page
 at
 this place is null. :-(

 Hi again,
 
 I tried out that code you mentioned here.
 WebSession.get().getPageManager().getPage(int i) returns
 IManageablePage
 which is not applicable as argument for newAjaxRequestTarget.
 
 cast it
 it is known that in your environment you don't use any custom 
 IManageablePage/IRequestablePage impls (see IPageFactory)
 
 
 
 The second thing is how do I get the instance of a page by
 class
 with
 the
 last page id
