Ough!, yes, there are two event listeners for click,. (Knockout, good
guess!), I think I'll try to make two components separately or use different
events. 

Do you think is feasible use two events in the same
component  ?, for example,. an 'event: {onfocus}' from Knockout and the
AjaxFallbacklink?

Thanks a lot Martin,.

Re: Global Ajax Event Handler

[Tobias Soloschenko]

The usecase requires it :-) I send an example to you.

I hope this will be possible because then you are also able to do ajax requests 
from embedded jsp files. :-D

thanks anyway!

Re: Referencing DataTable rows within the table column header

[Paul Bors]

Another piece of advice,

Avoid unnecessary casts (Wicket 6 supports generics) and try not to use
code to navigate the wicket component tree unnecessary like this line of
code:

WebMarkupContainer container = ((WebMarkupContainer)
dropDownChoice.findParent(DataTable.class).get(1));

Get familiar with the best practices documented at:
http://wicket.apache.org/guide/guide/single.html#bestpractices

You should give the free guide a read back to back and treat it as your
bible until you get a bit more intimate with Wicket :)

Other resources available for you to learn and master Wicket are the Wicket
Stuff (http://wicketstuff.org/) and the examples at:
http://www.wicket-library.com/wicket-examples-6.0.x/index.html

Get familiar to those as well.

For a filter toolbar see:
http://www.wicket-library.com/wicket-examples-6.0.x/repeater/wicket/bookmarkable/org.apache.wicket.examples.repeater.DataTableFilterToolbarPage;jsessionid=03E1374082C8198F0F052CED6E54F7A1?0

Although is not using a drop-down but you'll get the idea :)

Re: Referencing DataTable rows within the table column header

[Paul Bors]

Hey Ephraim,

At Knoa for the console code I created an API around those components.
You don't have to re-invent the wheel, all you have to do is get familiar
with the console commons and which DropDown component to use.

Remember wicket is a component driven framework similar to Swing.

I would recommend using one of the Ajax enabled drop downs and override the
method to refresh the data table rows of interest. There are plenty of
examples in the console's code base... look at how other table such as the
ones for the End User attributes are refreshed or how the edit button in a
table cell will turn the table row into form components. Use the same
principle.

Also, if this is just a filter toolbar, then look at how other Ajax filter
toolbars work and you won't loos focus of the drop down since it's Ajax
that does the refresh.

If you are to re-implement this from scratch and re-invent the wheel you
can also but I won't recommend it.
Just look over the current available components in your commons API and use
the appropriate one, or extend it and make it do what you need.

Martin was referring to the event mechanism build in Wicket documented in
the Wicket Guide at:
http://wicket.apache.org/guide/guide/single.html#advanced_1

But for a simple filter toolbar you don't need to get that complicated.

RE: Referencing DataTable rows within the table column header

[Ephraim Rosenfeld]

Hi Martin:



Thank you for your quick response.



I was initially updating the entire table, but that was causing me to lose 
focus from the drop-down menu in which I made the selection. Also, my hope was 
that I could update as few row items/components as possible, thereby expediting 
the table-refresh process.



When you mention 'Wicket's Event System', are you referring to inter-component 
events, like the example portrayed here: 
http://savicprvoslav.blogspot.com/2012/06/wicket-15-inter-component-events.html



Regards,



- Ephraim

Re: Problem getting data from a 'CharSequenceResource'

[Martin Grigorov]

Hi,

The  element has two JavaScript event listeners for 'click' event - one
by Wicket's AjaxFallbackLink and another by (Knockout.js ?!) data-bind
attribute.
The order of their execution is not determined.
If Wicket's listener is called first then it will get the old value:  null,
click1, click2, etc.
While data-bind's listener will get: click1, click2, click3, etc.

Problem getting data from a 'CharSequenceResource'

[manumoreno]

Hi, I need some advice to get data from a CharSequenceResource:

The Resource:



The request is provided by an asynchronous ajax request (from JQuery) 
to a url like 'http:///getjson'



and that is mounted as:




The component is an   tag, binded in wicket,.





The 'click: save' launchs the $.ajax.

The problem is that  is Ok, 
but  is first a null string and later is desynchronized, 
it writes one string from behind.

How can I refer to that string from the AjaxFallbackLink?, the
"MyResource._str" reference
is obviously incorrect. :(

Thx

Referencing DataTable rows within the table column header

[Ephraim Rosenfeld]

Hello All,

I am creating a table with a DropDownChoice component in the header of one of 
the columns. When a selection is made in the drop down in the column header, I 
want to update all of the rows in the table.

Would the following snippet be the best approach to reference each row Item 
component from the column header, or is there an alternative to using the get() 
method?

Thank you in advance,

- Ephraim

WebMarkupContainer container = 
((WebMarkupContainer)dropDownChoice.findParent(DataTable.class).get(1));
   DataGridView gridView  = 
(DataGridView)container.get(0);
   for(int i = 0; i < NUM_OF_ROWS; i++) {
   Item item = (Item)gridView.get(i);
// do row updates
}

RE: Global Ajax Event Handler

[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 ;)

Hi, all. I'm traveling at the moment, but I plan to be back in San

Re: Global Ajax Event Handler

[Tobias Soloschenko]

Ok the id is now generated right - but the code to get the page by the given 
page id is still returning null if the ajax call is made.

Re: Global Ajax Event Handler

PageRequestHandlerTracker.getLastHandler(RequestCycle.get()).getPageId() ? Is 
this a valid Way to get the last pageid?

Re: Global Ajax Event Handler

[Tobias Soloschenko]

Thats the point. It is not used within a Component / Behavior - so I cant use 
getPage() ...

Re: Global Ajax Event Handler

[Martin Grigorov]

The UrlGenerator class is used somewhere where the Page is available, no ?
In SomeComponent/SomeBehavior:

UrlGenerator generator = new UrlGenerator();
Url url = generator.generate(getPage().getPageId());

Session.get().getPageManager().getPage(exisingAndNonExpiredPageId) is the
way to get a reference to the page.
Wicket uses this API internally every time you click a link or button.

Re: Global Ajax Event Handler

[Tobias Soloschenko]

And thats the question I was looking for - how do I get the current page id
within the class that generates the url which is no component and the
second question was how do I get the page to that id, because (Page)
WebSession.get().getPageManager().getPage(i.get()) returns null for int i
0-10, event if I cleared the browsers cache / restarted the server.

kind regards and big thanks for all the help!

AuthenticatedWebSession.authenticate() not being called

[Lucio Crusca]

Hi all,

in a webapp that worked until yesterday (and that has worked for the last
2 years), the AuthenticatedWebSession.authenticate() method is not being
called anymore. I have MySession class that extends
AuthenticatedWebSession. The MySession constructor gets called correctly.
I use a standard SignInPanel: when I click "Sign in" the page reloads but
the code execution doesn't reach the breakpoint at the first line of
authenticate() in MySession. The authenticate() method does have the
@Override annotation, so I'm sure it has the correct signature.

Changes I've made since yesterday are only to the css, some HTML, a few
new initParameters in web.xml, but nothing directly related to the login
process... any clue about what could be causing that behavior? What should
I check first?

Btw, no, I didn't commit the code yesterday before those changes, so now I
can't revert, my bad.

Re: Global Ajax Event Handler

[Martin Grigorov]

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.

Re: Global Ajax Event Handler

[Tobias Soloschenko]

The method getPage() is not available at the place where I'm building the
link - I'm not within a component and I try to get the page by content of
the session. :-)

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

Re: Global Ajax Event Handler

[Martin Grigorov]

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 =

I dont know how to get the current pageId but from the Session. The page at
this place is null. :-(

Re: CouldNotLockPageException while trying 'inspect' option of Debug bar

[Martin Grigorov]

Can you reproduce this in a simple quickstart app ?

AbstractAjaxTimerBehavior will send a request on the defined timeout, but
the processing of this request should be fast enough. Check what you do in
#onTimer() callback.

it is known that in your environment you don't use any custom
IManageablePage/IRequestablePage impls (see IPageFactory)

Wicket logs

[dharmendra pandey]

Hi,

My application is deployed on PRODUCTION environment and I set our
application log level (Wicket Application to deployment mode)

After override/setting the method below we are seeing lots unnecessary
wicket logs info in file.


  public RuntimeConfigurationType getRuntimeConfigurationType() {

return RuntimeConfigurationType.DEPLOYMENT;

}

Please suggest,

Regards
Dharmendra Pandey

Re: Global Ajax Event Handler

[Tobias Soloschenko]

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.

The second thing is how do I get the instance of a page by class with the
last page id not from within a component (this would be simple getPage())?

Re: CouldNotLockPageException while trying 'inspect' option of Debug bar

[Rakesh A]

Hi,
Strange thing is, even if I increase the request timeout to 5mins using
"org.apache.wicket.settings.IRequestCycleSettings.setTimeout(Duration)", I
get the same exception.

I use Wicket 6.15.0, pages are unversioned & page uses
'AbstractAjaxTimerBehavior'.
Does 'AbstractAjaxTimerBehavior' cause this lock?

Regards,
Rakesh.A

Re: How to register a global resource with dependencies?

[Martin Grigorov]

This is OK.
Override Component#renderHead() or Behavior#renderHead() and list all
references that are needed.
You can also
use org.apache.wicket.Application#getHeaderContributorListeners().add(new
IHeaderContributor() { #renderHead() {...} }) to define which header items
should be contributed for every request.

The same is valid for any other (non-shared) resource reference.
Just create a PackageResourceReference (e.g. Css or JS) and define the
scope class and the relative path. Or UrlResourceReference with the Url.
Define the dependencies.
Later if you need to change the scope/relativePath/url just do it. All
users of the reference will have the update for free.

Re: How to register a global resource with dependencies?

[Tobias Soloschenko]

You could use resource bundles, define all ResourceReferences within the
bundle and within each ResourceReference their dependencies. If you would
use any resourcereference within a renderHead method, all dependencies and
resources would placed at the right position and you would save some
requests.

Re: CouldNotLockPageException while trying 'inspect' option of Debug bar

[Martin Grigorov]

The Inspector tries to get a reference to the page by its id to be able to
get a list of its components.
But another thread is already acquired the lock to this page... It seems to
write the page's markup to the browser but I cannot say why it does this
for more than a minute.

Re: How to register a global resource with dependencies?

[brushmate]

Thanks for your answer. So everytime I want to reference a resource, I have
to declare its dependencies?

I want to register it globally, because I can use it on different pages then
and if the path to the resource changes in the future, I only need to update
it at one place.

Re: How to register a global resource with dependencies?

[Martin Grigorov]

Hi,

You register the IResource with getSharedResources().add(String name,
IResource resource) but later you need to reference it with
SharedResourceReference(name) to be able to use it. You can override
SharedResourceReference's
getDependencies() to declare the JQuery dependency.

Why do you need to use shared resources at all ?
What benefit do you see ?

CouldNotLockPageException while trying 'inspect' option of Debug bar

[Rakesh A]

Hi,

I was trying to analyze my wicket page, by adding Wicket debug bar. When I
click on the 'Inspector' option in Wicket debug bar I get a
CouldNotLockPageException. Thread dump logged is provided below, I couldn't
understand much from it, can anybody point me towards why I am getting this
exception.


Thanks,

[Tobias Soloschenko]

You can get the JQueryResourceReference used by Wicket like this:

getJavaScriptLibrarySettings().getJQueryReference()

How to register a global resource with dependencies?

[brushmate]

Hi,I want to register a JS file globally, but it depends on jQuery. The user
guide says that rsources can be registered with
getSharedResources().add(String name, IResource resource). But since it
takes an IResource, I can not declare the dependencies with overriding
getDependencies() like I would do with a ResourceReference. So how can I
register a global JavaScript resource that depends on jQuery?

Re: Global Ajax Event Handler

[Tobias Soloschenko]

I only wrote some pseudo code to show what I want to do. In simple words:

I want to write javascript code that invokes a method on the server side. The 
method on Server side is going to refresh components. Everything should work 
without Rendering the javascript code within a wicket page / component.

Kind regards

Re: Global Ajax Event Handler

[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

RE: Global Ajax Event Handler

[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?1&SourcesPage_class=org.apache.wicket.examples.events.DecoupledAjaxUpdatePage
 for a good example.

Best,
Marvin

Re: Global Ajax Event Handler

[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

[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.

kind regards

Global Ajax Event Handler

[Tobias Soloschenko]

Hi all, 

is there a way to register a global ajax event handler within Wicket? For 
normal there is the AbstractDefaultAjaxBehavior which is added to a component. 
And then the CallbackScript can be obtained and used within a 
OnDomReadyHeaderItem for example.

Is there a way to do this on application level so that Im able to get the 
CallbackScript from the instantiated Application? 

kind regards

Re: JavaSerializer - Error serializing object class

[Martin Grigorov]

Hi,

This is a well known issue with CDI+EJB. It has been discussed few times
here and other forums.
CDI injects non-Serializable objects for EJB beans.
A workaround is to use a delegate CDI bean to lookup the EJBs. I.e. instead
of @Inject-ing EJBs in Wicket components inject a scoped CDI bean that
injects the EJBs in itself.
So the usage in Wicket would be:

public class MyComponent extends ... {
  @Inject MyCDIBean cdiBean;
  ...

  cdiBean.getEjb().doSomething();
  ...
}

I reported it to Sonatype:
https://getsatisfaction.com/sonatype/topics/wicket-6-17-0-in-central-but-not-on-search-maven-org
.

We use search.maven.org at artifact-listener.org so Wicket 6.17.0 is
still unannounced there too...

[Maxim Solodovnik]

you can only have Serializable classes stored in the page
you can have DTO or ID stored if it is impossible
