Re: page mounting
Hi, in public IRequestHandler mapRequest(final Request request) the mappers will be sort by: Collections.sort(list); So there is no chance to influence the order of the mappers :( regards britta Am 25.02.2013 11:18, schrieb Martin Grigorov: Hi, I've just tried it in a quickstart and my conclusion seems to be valid. I am able to reproduce the problem with the initial order and to workaround it with the reverse order. To debug what happens in your case you can put a breakpoint in org.apache.wicket.request.mapper.CompoundRequestMapper#mapRequest(). Check what is the order of 'list' after the sorting.

Re: page mounting
Hi, This #sort() sorts by the compatibility score the mapper returns for this Request. If two or more mappers return the same score then the order in the list depends on the order of the mounting in Application#init(), i.e. the order of insertion in the non-sorted list.

wicket6-ajax-anchorbrowserhistory
Hi wickers ! First, I'd like to thank all the people that have helped me from this forum: Second, I've created a github repo to place a pair of classes that I'm using in my projects. https://github.com/obaisdefe/wicket6-ajax-anchorbrowserhistory This code is based on the work of vmontane, at https://github.com/vmontane/wicket-ajax-bookmarks ( Also, special thanks to vmontane ) There are two classes: - A link that changes the hash of the url, the AnchorAjaxLink (really it has no ajax action) - A behaviour to capture, via ajax, the changes made to the hash of the url, HistoryAjaxBehaviour They are based on jQuery and they are working in my code, so feel free to use them The examples can be found in this repo https://github.com/obaisdefe/wicket6-ajax-anchorbrowserhistory-example Any suggestion or enhacement is wellcome !!

Re: Integrating Wicket with an Angular app
Ernesto Reinaldo Barreiro-4 wrote I want this special page to be be stateless, so I'm planning to serve JSON needed via mounted resources. I've been also playing with a similar idea. Nice to hear that there are similar attempts going on. In my case I decided to serve the JSON through a Spring Controller http://blog.springsource.org/2009/03/08/rest-in-spring-3-mvc/ http://blog.springsource.org/2009/03/08/rest-in-spring-3-mvc/ . I feel this makes the service interface more straightforward to implement - compared to mounted resources. The motivation for me to do this is that I get to package the angular application like a standard java web application, and it can then be deployed to a servlet container like the other applications. If needed, I also get a session for the application (I can for example check that the service calls are made in a session + get hold of the user information, etc). Also I have found that none of the javascript frameworks that I have studied so far have decent support for i18n - with this I could use Wicket for that. Wicket has also other features that are useful for this like javascript and css resource serving. (I haven't done this yet but) I think I could add the required js resources in all of my panels and wicket handles them so that the javascripts are included in the resulting page only once. I will try to get a sample application made to demonstrate this. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Integrating-Wicket-with-an-Angular-app-tp4656794p4656820.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Wicket 6.5.0 upgrade, Extensions Wizard, ApplyState() not called
Hi, If i put a breakpoint in renderCount (it gets called a lot) But the resolvePageInstance only gets called once per request, It seems to have the same renderCount Value that is on the current page. E.G. The page is displaying booking?14-1 for all event listeners. If i change the GroupSize via the Dropdown then the PageProvider#getPageInstance() is being called with e.g. pageId=14 renderCount = 1. The Ajax response contains event Listeners for all the passenger names textboxes, all the URLs reference booking?14-1.IBehaviorListener as part of the URL, and when i type in a passenger name it looks like they are correctly called, but once i click Next the Names are lost. The Next Button reference a form with the following URL ./booking?14-1.IFormSubmitListener-wizard-form Yet If i Click NEXT then the page refreshes again and all the Links rerender with booking?14-3 This is consistent with wicket 1.5.5 on the Live site in the same browser, if i click Next without any passenger names it resets the Booking page, and moves from e.g 14-1 to 14-3.. I'm not 100% sure where i need to go from here.

Can a batch job pass back its completion results to Wicket session?
Hi all,
I'm hooking up a data import batch job with Quartz to Wicket and have
struck an issue - how do you notify a Wicket page that the batch job is
complete?
I originally planned to update the Wicket session with the running count of
how many items are processed. However, the Wicket request cycle expires so
it is not possible to update the session after the page is rendered.
To create the job:
JobDataMap dataMap = new JobDataMap();
dataMap.put(service, getService());
dataMap.put(deck, deck);
dataMap.put(importType, importType);
dataMap.put(fieldMapping, fieldMapping);
dataMap.put(fileUploaded, fileUploaded);
dataMap.put(totalRecords, prevImportSummary.totalRecordsInImport);
dataMap.put(callback, this);
// Create a new job with a basic trigger
JobDetail job = newJob(DataImportJob.class
).usingJobData(dataMap).build();
Trigger trigger =
newTrigger().startNow().withSchedule(simpleSchedule()).build();
try {
// Schedule the job for immediate start
TorScheduler.getScheduler().scheduleJob(job, trigger);
} catch (SchedulerException se) {
TorScheduler.getLogger().error(se.getMessage());
throw new TorException(Cannot start the data import job);
}
The data import job uses a callback to the Wicket page:
callback.updateTotal(totalRecords);
callback.updateProgress(/* 0 */ totalRecords, false); // TODO:
Temporarily skip the progress bar page
// Now add the entries to the repository
ImportSummary importSummary = dataImportProcess.commit(callback);
callback.updateImportSummary(importSummary);
The callback has this implementation (in the page):
public void updateProgress(int count, boolean error) {
// Attempt to reuse the same session as before (left open)
session.setAttribute(importItemsDone, (Integer) count);
session.setAttribute(importIsInError, (Boolean) error);
}
@Override
public void updateTotal(int total) {
// Attempt to reuse the same session as before (left open)
session.setAttribute(importItemsTotal, (Integer) total);
}
@Override
public void updateImportSummary(ImportSummary importSummary) {
// Attempt to reuse the same session as before (left open)
session.setAttribute(importSummary, importSummary);
}
However, I get this exception when attempting to update the Wicket session
with the progress counter:
java.lang.IllegalStateException: Cannot set the attribute: no RequestCycle
available. If you get this error when using WicketTester.startPage(Page),
make sure to call WicketTester.createRequestCycle() beforehand.

at
org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:557)
Is this the best approach? Or should I attempt to use methods on the Quartz
scheduler to get the current progress of the batch job from within
AbstractAjaxTimerBehavior.onTimer( )?
I am using the JQWicket (jQuery UI) progress bar... with a 5 second delay
on updates to the page.
Cheers,
Nigel

I would look at Observable and Observer class in java to achieve signal

on updates to the page.

How to automatically add a parameter to every request
Hello, I am currently in the process of migrating an application from Wicket 1.4 to Wicket 6. In my application I have a parameter that needs to be part of every request (kind of like pageMaps used to be in 1.4). This means I have to check each request to see if the parameter is there and if not create a new one and add it. In Wicket 1.4 I had logic in the resolve() method of the WebRequestCycleProcessor where I basically called setResponsePage() with the new parameter and threw a AbstractRestartResponseException(). In Wicket 6 I was able to achieve the same by creating a custom Mapper that extends the MountedMapper. In this Mapper I added logic to the parseRequest method to check if the UrlInfo includes the parameter and if not create a new UrlInfo instance based on the original one that includes the parameter. This works but it requires that all pages are mounted with this specific Mapper. Is there a better way to add this logic so that it automatically applies to every request and does not require the developers to use the custom mapper? Thanks, Florian

Re: Handle JSON response
If you want to see a simple project using Jackson to render JSON on the page
take a look at:
http://wicket-continuous-calendar.GoogleCode.com/
Or a bit bigger one:
http://wicked-charts.GoogleCode.com
Or poke around other open source code projects in Wicket that use those
dependencies in Maven.

Re: Can a batch job pass back its completion results to Wicket session?
Hi,
I remember I have done this by creating a class that serves a progress
watching context and sharing an instance of this class between Wicket
Session (or a page or component) and the quartz job. This class acted as
a wire to pass information between the two threads (e.g. progress,
cancel the JOB, etc). I also used an AJAX timer too poll server. I think
there is an example of how to do that at
http://code.google.com/p/antilia/source/browse/#svn%2Ftrunk%2Fcom.antilia.export%2Fsrc%2Fcom%2Fantilia%2Fexport%2Fpdf
Thought code is quite old...

Hi all,
I'm hooking up a data import batch job with Quartz to Wicket and have
struck an issue - how do you notify a Wicket page that the batch job is
complete?
I originally planned to update the Wicket session with the running count of
how many items are processed. However, the Wicket request cycle expires so
it is not possible to update the session after the page is rendered.
To create the job:
JobDataMap dataMap = new JobDataMap();
dataMap.put(service, getService());
dataMap.put(deck, deck);
dataMap.put(importType, importType);
dataMap.put(fieldMapping, fieldMapping);
dataMap.put(fileUploaded, fileUploaded);
dataMap.put(totalRecords, prevImportSummary.totalRecordsInImport);
dataMap.put(callback, this);
// Create a new job with a basic trigger
JobDetail job = newJob(DataImportJob.class
).usingJobData(dataMap).build();
Trigger trigger =
newTrigger().startNow().withSchedule(simpleSchedule()).build();
try {
// Schedule the job for immediate start
TorScheduler.getScheduler().scheduleJob(job, trigger);
} catch (SchedulerException se) {
TorScheduler.getLogger().error(se.getMessage());
throw new TorException(Cannot start the data import job);
}
The data import job uses a callback to the Wicket page:
callback.updateTotal(totalRecords);
callback.updateProgress(/* 0 */ totalRecords, false); // TODO:
Temporarily skip the progress bar page
// Now add the entries to the repository
ImportSummary importSummary = dataImportProcess.commit(callback);
callback.updateImportSummary(importSummary);
The callback has this implementation (in the page):
public void updateProgress(int count, boolean error) {
// Attempt to reuse the same session as before (left open)
session.setAttribute(importItemsDone, (Integer) count);
session.setAttribute(importIsInError, (Boolean) error);
}
@Override
public void updateTotal(int total) {
// Attempt to reuse the same session as before (left open)
session.setAttribute(importItemsTotal, (Integer) total);
}
@Override
public void updateImportSummary(ImportSummary importSummary) {
// Attempt to reuse the same session as before (left open)
session.setAttribute(importSummary, importSummary);
}
However, I get this exception when attempting to update the Wicket session
with the progress counter:
java.lang.IllegalStateException: Cannot set the attribute: no RequestCycle
available. If you get this error when using WicketTester.startPage(Page),
make sure to call WicketTester.createRequestCycle() beforehand.

Re: Can a batch job pass back its completion results to Wicket session?
Thanks Paul and Ernesto,
After much stuffing around, I managed to get this to work: modifying the
JobDataMap within the Quartz job. However, you must re-publish the map
after it has been changed, as Quartz serializes it and doesn't update it
until after the job finishes executing. You might also need the
@PersistJobDataAfterExecution and @DisallowConcurrentExecution annotations
on the Quartz job to make it stateful.
The callback:
if (callback != null) {
callback.updateProgress(resultSummary.successullyImportedRecords +
resultSummary.unSuccessullyImportedRecords, false);
}
The updateProgress( ) callback on the Quartz job:
public void updateProgress(int count, boolean error) {
try {
dataMap.put(results_counter, (int) count);
dataMap.put(results_error, error);
// Update the job detail and the associated data map (serialized in
RAM?)
TorScheduler.getScheduler().addJob(jobDetail, true);
} catch (SchedulerException e) {
e.printStackTrace();
logger.error(Error when updating the job details: + e.getMessage());
}
}
The Progress Bar within the Wicket page:
add(new AbstractAjaxTimerBehavior(Duration.seconds(3)) {
private static final long serialVersionUID = 1L;
@Override
protected void onTimer(AjaxRequestTarget target) {
TorSession session = TorSession.get();
progressbar.value(target, counter);
JobKey jobKey = (JobKey) session.getAttribute(
importJobKey);
System.out.println (job key: + jobKey);
boolean error = false;
try {
Scheduler scheduler = TorScheduler.getScheduler();
JobDetail jobDetails = scheduler.getJobDetail(jobKey);
if (jobDetails == null) {
System.out.println (Job finished?);
PageParameters pp = new PageParameters().set(p, deck
.getId().getTudi());
setResponsePage(Wiz14ImportComplete.class, pp);
return;
}
JobDataMap jobDataMap = jobDetails.getJobDataMap();
counter = jobDataMap.getIntValue(results_counter);
error = jobDataMap.getBooleanValue(results_error);
} catch (SchedulerException e) {
error(Error with import batch process: + e.getMessage());
setUpdateInterval(Duration.NONE);
target.add(curr);
return;
}
if (error) {
error(Error occurred during the import batch process);
setUpdateInterval(Duration.NONE);
} else {
// Redirect if we get the max count
if (counter = maxItems) {
PageParameters pp = new PageParameters().set(p, deck

setResponsePage(Wiz14ImportComplete.class, pp);

Re: How to automatically add a parameter to every request
Hi, You can also use a custom root mapper that does this for all wrapped mappers. See how HttpsMapper and CryptoMapper work.

In my application I have a parameter that needs to be part of every request (kind of like pageMaps used to be in 1.4). This means I have to check each request to see if the parameter is there and if not create a new one and add it. In Wicket 1.4 I had logic in the resolve() method of the WebRequestCycleProcessor where I basically called setResponsePage() with the new parameter and threw a AbstractRestartResponseException(). In Wicket 6 I was able to achieve the same by creating a custom Mapper that extends the MountedMapper. In this Mapper I added logic to the parseRequest method to check if the UrlInfo includes the parameter and if not create a new UrlInfo instance based on the original one that includes the parameter. This works but it requires that all pages are mounted with this specific Mapper. Is there a better way to add this logic so that it automatically applies to every request and does not require the developers to use the custom mapper?

Re: OnDomReadyHeaderItems
Hi,
DomReady JS is executed manually in Ajax response:
1) execute prepend JS
2) replace components
3) execute ondomready
4) execute append JS
As Ernesto suggested you can use:
if (requestCycle.find(AjaxRequestTarget.class) == null) {
response.render(OnDomReadyHeaderItem.forScript(...));
}

I don't know if there is a better way... but can always check if you are
NOT in a middle of and AJAX request cycle and if so contribute your script.

With Wicket 6.5.0, is it expected that scripts added in
Behavior.renderHead
( OnDomReadyHeaderItem.forScript( ... ); ) will be re-rendered and
executed
for partial DOM updates triggered via Ajax?
If so, is there a way to add a Script to a Behavior such that it only
renders on a full page re-render?
