Re: log4j MDC IRequestLogger

[Francois Meillet]

I ended up with a custom RequestCycle

@Override
public boolean processRequestAndDetach() {

boolean result;
try {
result = processRequest();
} finally {
detach();
}

popMDC();

return result;
}

@Override
protected void onBeginRequest()
{
pushMDC();
}

log4j MDC IRequestLogger

[Francois Meillet]

Dear All,

I use the Mapped Diagnostic Context concept 
https://logging.apache.org/log4j/2.x/manual/thread-context.html).

Using log4j 2.x and a specific AbstractRequestCycleListener, 
I overrided onBeginRequest() to perform a ThreadContext.push(id) 
and onDetach(RequestCycle cycle) to perform a ThreadContext.pop();.

So far so good for all the logs but the IRequestLogger's logs.

I notice that the IRequestLogger # performLogging() is called after the 
RequestCycle # onDetach() has been called.

I would like it to happen before !
Is that possible ?

 But this pros can be easily done by creating a library of links to all

Re: BeanValidation --> wrong maxlength value in TextField

[Francois Meillet]

Hi Martin,

Sorry for the  .
I miss it.

Thanks for your insights.

In the ConstraintIterator's constructor, the set returned by the Hibernate 
validation implementation (Set<ConstraintDescriptor> constraints)
is unordered.

Either by calling
Set<ConstraintDescriptor> constraints = propDesc.findConstraints()
.unorderedAndMatchingGroups(groups)
.getConstraintDescriptors();

or  
BeanDescriptor beanDescriptor = 
validator.getConstraintsForClass(IdentityRegistrationModel.class);
PropertyDescriptor propertyDescriptor = 
beanDescriptor.getConstraintsForProperty(property);
Set<ConstraintDescriptor> constraintDescriptors = 
propertyDescriptor.getConstraintDescriptors();

As there are 2 annotations with the same type (Size) per property, 
@Size.List({
@Size(min=4, message = "{firstName.sizeToSmall}"),
@Size(max=50, message = "{firstName.sizeToBig}")
})
the last call to SizeTagModifier # tag.put() wins and maxlength may be wrong 
(Integer.MAX_VALUE).

The validation itself, when form is submitted, is OK.
Only the maxlenght may be wrong.   
   

One way to fix this problem :

In the ConstraintIterator's constructor, before populating the stack,
an iteration could be made over the 'Set<ConstraintDescriptor> constraints' 
to find ConstraintDescriptor with Annotation's type = Size,
and if there is more than one, the biggest (=Integer.MAX_VALUE) max value 
should be removed.

The other way is to add an AttributeModifier to the textfield, new 
AttributeModifier("maxlength", new Model<>(50))). 
Which I do.

Le 23 juil. 2015 à 22:44, Sven Meier s...@meiers.net a écrit :

 Hi,
 
 you're SkeletonPage is interrupting its normal page rendering 
 (#onInitialize() being triggered late from WebPageRenderer).
 Thus in WebPage#validateHeaders() the page doesn't find its 
 HtmlHeaderContainer, which it expects to exists already if rendering 
 succeeded successfully.
 
 So a) the error message is misleading and b) we may be able to improve this 
 (e.g. checking #hasBeenRendered() before validating the headers).
 Please create a Jira issue for this.
 
 For now you could just override #onConfigure() instead of #onInitialize().
 
 Have fun

 Hi Wicketers,

 A cookie has to be updated.
 To trigger the update, a session attribute is set to false.
 
 Then the user is redirected to a page : setResponsePage( new ResultPage() )
 ResultPage extends Skeleton
 
 In the Skeleton page, if the session attribute is set to false, the cookie

 When I throw a NonResettingRestartException() in a page where I also

 You probably forgot to add a body or head tag to your markup since no

Re: Wicket page serialization what causes delay?

[Francois Meillet]

There is very little chance that the problem come from the serialization.

Do you use the Open Session in View pattern ? with some OpensessionInViewFilter 
filter ?
I guess when the page is serialized, some requests are done against the 
database 
to load collections or initialize proxies that have been touched. (look at your 
lazy entities relations)

If not you should use the famous LoadableDetachableModel
see http://ci.apache.org/projects/wicket/guide/7.x/guide/modelsforms.html

 Hi Lois,
 
 I am not aware of this... But I'm interested to the answer :)
 I was looking for a nice js graph, based on jQuery possibly and found that
 best matches my requirement: vis.js, arbor.js  cytoscape.js
 
 arbor.js is highly deprecated,
 cytoscape.js is good and jQuery oriented, but requires additional
 libraries
 depending on what type of graph we want to display,
 so I'll probably go for vis.js (ASFv2 licensed) because it is really
 simple
 to use and it just works! :)
 
 I am already busy with some other wicket integrations so I don't know
 (now)
 if I will make it a public project... But if someone would like to dig
 into
 a wicket-vis project, and maintain it, I will be glad to help... In the
 meantime, will I try to publish a showcase in a week or two...
 
 Best regards,

Re: Stateful panel.

[Francois Meillet]

One way of doing this : 


1) go to your detail page
add( new LinkVoid(detail) {

@Override
public void onClick() {
setResponsePage(new YourPage(getPage().getPageReference()));
}
});

public YourPage(PageReference pageReference) {
this.pageReference = pageReference;
}

2) back to the list
add( new LinkVoid(list) {

@Override
public void onClick() {
setResponsePage(pageReference.getPage());
}
});

 Hi,
 
  I need some help/ideas on list and search state in panel. I have two 
 panels in a page, one for searching, i.e., which produces a list of items in 
 a datatable which has paging. All this works well. Now, if I change 
 pagination links and then select one of the items in the list, it'll take me 
 to a details panel of that item. How can I remember (store) the state of the 
 previous list, so when I click a back link/button in the details panel, I 
 return to the list panel where the list will have the same state as when 
 I left it?
 
 Note: I am using the event for replacing the panel in the page.
 
 I had attached a quickstart project with it.

Re: Wicket Listmodel (attach objects to model but not to list)

[Francois Meillet]

It's not possible.

Look at the ListModel's consructor.

public ListModel(ListT list)
{
setObject(list);
}

And the setObject() method implementation, which is in the superclass, is

@Override
public void setObject(T object)
{
if (!(object instanceof Serializable))
{
object = createSerializableVersionOf(object);
}
this.object = object;
}

 Hi,
 
 Once 7.0.0 is released I think we should create a branch for Wicket 8 and
 see what we could benefit of Java 8.
 Having less verbose Wicket would be great! But not on any price! Lambdas
 are both harder to debug and produce bigger stack, so we should decide
 carefully.
 Other things to consider:
 - whether to use Optional for AjaxFallback** components. I don't remember
 the exact reason why Igor's Optional didn't make it, but we may reevaluate
 - use the new DateTime APIs for wicket-datetime (new Converters, etc.)
 - ???
 
 We should also ask the community what they don't like in Wicket and what
 they would like to be added to make it better.

form AjaxFormComponentUpdatingBehavior validation

[Francois Meillet]

Hi All,


1) I have a Form with a Textfield which has a AjaxFormComponentUpdatingBehavior 
(blur)

When the entire form is submitted (via an AjaxButton) 
the ajaxFormComponentUpdatingBehavior.onEvent() is called
then the formComponent.validate() is called
and then when the form.validate() is called
formComponent.validate() is called again.

Could it possible to avoid this double validation ?
Do I have to override AjaxFormComponentUpdatingBehavior.onEvent()  ? ... or 
there is a simple way to do this ?



2) is it possible to remove a formComponent's validator just after the 
button.submit() and before the form.onFormSubmitted() is called



3) When the I leave a page (without submitting) with a formComponent which has 
a AjaxFormComponentUpdatingBehavior (blur),
the ajaxFormComponentUpdatingBehavior.onEvent() is called and then the 
validation.
Can I avoid the ajaxFormComponentUpdatingBehavior.onEvent()  ?


Best regards
François Meillet

Re: form AjaxFormComponentUpdatingBehavior validation

[Francois Meillet]

OnDomReadyHeaderItem.forScript('Thanks Sven')

I also added OnEventHeaderItem.forScript(window, onunload, 
mousedownHappened = true)
to the button.


Everything work nicely except when an onunload event is fired and the textfield 
is empty.
In this case the ajaxFormComponentUpdatingBehavior.onEvent() is called
and the formComponent.validate();

Re: ListPanel - update model

[Francois Meillet]

Hi Chris,

The ListModel keeps a reference on the model created at the first occurence of 
that line
pModel = new ListModelP(someService.caculate());

The simplest thing you could do is to reset the listpanel's model,
but this is not a good practice.

listPanel.setDefaultModel(model);

add(new AjaxFallbackLink(link) { 
@Override 
public void onClick(AjaxRequestTarget target) { 
pModel = new ListModelP(someService.caculate()); 
listPanel.setDefaultModel(pModel);
target.add(listPanel); 
} 
}); 


Using a specific model is much better
For example, using the int property flag we can do 

pModel = new ModelString() {
@Override
public String getObject() {
return flag_ + flag ;
}
};

final Panel listPanel = new ListPanel(itemList, pModel); 
add(listPanel); 

add(new AjaxFallbackLink(link) { 
@Override 
public void onClick(AjaxRequestTarget target) { 
flag++;
target.add(listPanel); 
} 
}); 


Have a look at https://wicket.apache.org/guide/guide/single.html#modelsforms

Re: Switching between wicket tabs

[Francois Meillet]

use parameters

PageParameters parameters = new PageParameters();
parameters.set(TAB_NUM, 3);
parameters.set(USERNAME_ID, username);

setResponsePage(YourCLaasContainingTheTabbedPanel.class, pageParameters);

and in your YourCLaasContainingTheTabbedPanel.class
extract the parameters

int tabindex = pageParameters.get(TAB_NUM).toInt();

and set tabbedPanel # setSelectedTab accordingly

Re: Possible memory leak in Wicket 1.5.12

Hi Satrix,

When the second constructor is used, with the inputsream argument,
the stream is open.

When this inputsream is opened ?

Can you show me the class when you open the stream ?

Did you moved the stream creation to the getImageData this morning ?

 Hi,
 
 It's used very rarely so it should not be a problem. However I've moved the
 stream creation from the constructor to getImageData method. 
 
 The important point here - it only happens when the crawler visits my
 website. When normal users visit my website the file descriptors are closed
 successfully.

Re: Possible memory leak in Wicket 1.5.12

[Francois Meillet]

Moving the stream creation, opening and closing it in getImageData is a good 
thing.
You should also remove the second constructor (with the inputstream argument).

Now with your tests classes with the WicketTester, (you do have tests ;-)  ), 
you can play yours pages with a debugger and see what happens.

Le 20 déc. 2014 à 11:40, Satrix satrix...@gmail.com a écrit :

 Actually I've checked the code in the second constructor and the stream is
 the ByteArrayInputStream instance. But I've moved the stream creation from
 the first constructor to the getImageData because that's the constructor I
 use to create the 99% of the images in my website.
 
 And yes I've changed it today.

 Hello,
 
 I've developed an Wicket website in Wicket 1.5.12. It's hosted on Glassfish
 server 3.1.2.2 and lately I've run into the following problem:
 
 The problem only occurs when a crawler (for example googlebot) visits my
 website and then when it's crawling, Glassfish opens a lot of file
 descriptors (for images) and doesn't close it. This leads to Too many open
 files exception and right after that my server crashes. Those file
 descriptors are open all the time - I've to restart the server to delete the
 file descriptors.
 
 So I wanted to ask if it's possible that it's a wicket related problem or
 it's just Glassfish problem ?
 
 Thank you for any help.

application#sessionUnbound(String sessionId) is called by Wicket

You should use a mapsessionid, yourSession

@Override

Yoursession  yoursession = yourmap.get(sessionId);
//

session invalidateNow vs invalidate

[Francois Meillet]

just a reminder 

session invalidateNow vs invalidate


if session#invalidateNow is called before a setResponsepage
then the application#sessionUnbound is called twice. 
as invalidateNow is invoked in session#detach.

ko
getSession().invalidateNow();
setResponsePage(Logout.class);

ok
# Invalidates this session at the end of the current request
getSession().invalidate();
setResponsePage(Logout.class);

I don't know CSVDataExporter but I noticed that the second bounded type

 Hi,
 
 I am trying to export data to csv in my wicket pages. I am using
 CSVDataExporter for this purpose. Due to some constraints I am not using it
 in conjunction to ExportToolbar. There is a link and on click of the link I
 am trying to call exportData() on instance of CSVDataExporter. 
 I am using AbstractExportableColumn for columns writing data to columns. 
 
 However I am getting a compile time error on exportData. Follwoing is the
 code (excelDataImport is the link here ):
 
 excelDataImport.add(new AjaxEventBehavior(onclick) {
   private static final long serialVersionUID = 1L;
 
   protected void onEvent(AjaxRequestTarget target) {
   ListIExportableColumnlt;AffiliateModel, 
 String, String columns = new
 ArrayListIExportableColumnlt;AffiliateModel, String, String();
   columns.add(new 
 AbstractExportableColumnAffiliateModel, String,
 String(new ModelString(Affiliate Name), name) {
 
   @Override
   public IModelString getDataModel(
   IModelAffiliateModel 
 arg0) {
   // TODO Auto-generated method 
 stub
   return null;
   }
   
   });
   
   try {
   new CSVDataExporter().exportData(new 
 AffiliateDataProvider(null),
 columns, new FileOutputStream(test.xls));
   } catch (FileNotFoundException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
   } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
   } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
   }
 
   
   
 
   }
   });
 
 The error message is  : The method exportData(IDataProviderT,
 ListIExportableColumnlt;T,?,?, OutputStream) in the type CSVDataExporter
 is not applicable for the arguments (AffiliateDataProvider,
 ListIExportableColumnlt;AffiliateModel,String,String,
 FileOutputStream).
 
 I think I did it all correctly (as per whatever knowledge I could get on
 this subject), am I doing something wrong here?
 
 Also, can anyone share with me some sample examples and description/details
 for CSVDataExporter? I have gone through example in  DataTablePage.java in
 wicket example but that is using  DataTable and ExportToolbar. 
 
 Thanks,
 Suvojit

Re: Error in java.lang.String during Internationalisation of a wicket project

[Francois Meillet]

When the toString() method of your class de.myproject.MyClass is called,
you get a LazyInitializationException.

This is from Hibernate

To get the LazyInitializationException's full explanation, see

Re: Stateful StatelessForm works most of the time. How to make it crash?

 Dear Wicket users,
 
 I believe I have found the cause of a long standing issue in my application.
 Basically, a form would submit with everything set to null or the default
 values even when the user filled in all the information. The problem is that
 this only happened once in a while and I was never able to reproduce it, so
 I couldn't figure out what was wrong.
 
 However, today I was looking at that code to reuse it somewhere else and
 something odd caught my attention. It turns out that my form is a
 StatelessForm when it shouldn't be. I don't remember why I made it like
 that, but I think it was because I was still learning Wicket at the time.
 Anyway, it always worked for me and for 99.9% of the users, so I was never
 able to identify the cause.
 
 I tried StatelessChecker and indeed it complains that the form is stateful.
 However, that still doesn't guarantee that this mistake is the cause of my
 problem. Can you think of any way to exploit this erroneous StatelessForm
 declaration so that it doesn't behave correctly?
 
 Thanks,
 
 Luis

Re: StringResourceModel with a defaultValue as model

In your Application.properties
you add the key key.to.be.good=theValue

 Hi all,
 is there any way to implement a StringResourceModel which allows to give

 First I tried to override getDefaultModelAsString() of Label. (is final)
 Than I tried to implement an extending 
 ModeledDefaultValueStringResourceModel, catching a 
 MissingResourceException on getObject() or load() and retrieving my own 
 ModelString defaultValue, but everthing is final here, too.
 
 So, Im not able to achieve this, right now.
 
 I would like to do this, because I have a dynamic way of giving buttons 
 a label depending of my Wizard-subclass (have my own 
 SpecialWizardButtonBar).
 
 And if a button label is not availabe I want to fallback somewhere, but 
 the default cannot be a StringResourceModel.
 
 Can someone help? Or is this a feature request and have to open a ticket?

 Hello!
 
 I have textfield backed by Integer Model object in the web app and a number
 field in the database.
 The maximum number the database can hold is less than Integer.MAX_VALUE so I
 have added a validator which checks that and reports the valid range. 
 
 The problem is that when the user enters a value larger than
 Integer.MAX_VALUE, the conversion fails and user recieves a generic message.
 
 Using BigInteger and BigDecimal everywhere in models seems excessive.
 And it seems I can't validate the raw input string before conversion? Would
 you consider adding this feature or is there a better way?

 In wicket 1.5 , it generate the following code :

 Wicket.Ajax.ajax({sc:cancel,c:id99,u:./page?19-1.IBehaviorListener.0-form-cancel,e:click,f:id97,m:POST});;

 value=submit
 input type=button class=btn btn-default name=cancel id=*canceldd*

 But I cannot find another submitdc or  canceldd string in the source

Re: NPE in AbstractSingleSelectChoice

[Francois Meillet]

When the DropDownChoice try to convert the submitted choice id back to the 
choice object
there is an iteration over the choices.
You get the NPE in this iteration because nullItem has no id.

Have a look to AbstractSingleSelectChoice's setNullValid(true) method to 
include a null value.
http://ci.apache.org/projects/wicket/apidocs/6.x/org/apache/wicket/markup/html/form/AbstractSingleSelectChoice.html#setNullValid(boolean)

Le 25 mai 2014 à 21:18, Marco Springer ma...@glitchbox.nl a écrit :

 Haven't run the code but my guess is that the idValue returns a null instead 
 of  0.
 Take a look at AbstractSingleSelectChoice.convertChoiceIdToChoice(String) 
 line 
 281. (Wicket 6.15.0)
 if(renderer.getIdValue(choice, index).equals(id)
 This would trigger a NPE if a null is returned, which would be the case with 
 your nullItem.

 Hi,
 
 
 
 I have a form with several question that a user must answer. If the answers
 are correct, an email is sent to the user and the user is returned to the
 login page. That's a bit abrupt for the user and I  would like to provide a
 simple modal dialog that confirms that the email is sent before sending them
 to the home page. However, if the answers to the questions are not correct,
 then a feedback panel must be displayed.
 
 
 
 I've looked at the approaches to providing a confirmation panel in this link
 https://cwiki.apache.org/confluence/display/WICKET/Getting+user+confirmation
 and other places, but I am having a problem with the approach. The
 JavaScript seems to run as soon as the button is clicked - before onSubmit
 or onValidate runs on the server. So I can't stop the pop-up from showing
 if the questions were not answered correctly.
 
 
 
 Does anyone know a way I can display the modal dialog only after validation
 has run?

Re: DiskDataStore errors in production

[Francois Meillet]

You need to increase the maximum number of file handles allowed by your system.

On linux/OSX
find open files limit per process: ulimit -n
count all opened files by all process: lsof | wc -l
list of processes and the number of file handles they have open: lsof | cut -d 
  -f 1 | uniq -c | sort -nr

className 
set the class of window (blue or silver by default)

unloadConfirmation
Display confirmation dialog if the user is about to leave a page (IE and FF).

why don't you load the job (with an eager fetching strategy) when you load

You use cascade=all on the job relation.

Job's instance is null because it doesn't have any non empty property.

Re: What is the default size of max per session in wicket

[Francois Meillet]

There is no simple response.
It depends on your non-functional requirements, on what you are trying to 
achieve, on the pages's size, on the types of model you use.

The api says:
IStoreSettings 
setMaxSizePerSession
Sets the maximum size of the File where page instances per session are stored. 
After reaching this size the DiskDataStore will start overriding the oldest 
pages at the beginning of the file.

I would say that 10mb is a good compromise.

 Hi,

 OOM in PermGen is not what you ask for.
 If you leak normal memory than the error would be with heap
  space.
 PermGen memory is used to keep the Class instances and interned
   Strings.
 If you deploy your app for first time then most probably you just
  need
   to
 set the proper initial and max value :
 -XX:PermSize and -XX:MaxPermSize.
 Use JConsole to see what size you need.

 If this error happens on redeploy then most probably you have a
ClassLoader
 memory leak, i.e. you keep references to Class instances and they
   cannot
be
 released so the PermGen is overloaded. Those are very tricky to be
 debugged.

 When I was using the normal JSESSIONID, it was properly ignoring it when it

 Although we don't know anything about your application structure, I tend to

 Assuming from the subject, that we are talking about OSGi modules (or rather
 bundles), making the application capable of that dynamism is surely
 possible. It simply depends on your decision of utilizing the OSGi
 programming model and execution environment. Do you have your application
 modules OSGi ready?
 
 Having a look a the wicket-distribution it seems to be OSGi-ready. You also
 may have a look at the Pax Wicket extension.
 
 So you're probably good to go.

You should migrate directly to verion 6.

You can write a unboundListener and register it in your sessionStore.

// logout timestamp in the database

In this case, override the onInvalidate() method in your custom session.

from the api : 
onInvalidate is a callback method that is executed when the user session is

either by explicit call to {@link org.apache.wicket.Session#invalidate()}

Re: wicket conversation scope - weld integration

[francois meillet]

It seems that you have more than one copy of weld in your claspath.

Try with that :

wicket-core
cdi-api
seam-conversation-spi
wicket-cdi

 Hi heapifyman,

 thanks for your reply. Yes i read it all. But the blog is from 2011 and is
 based on wicket 1.5. I downloaded the libs with maven, but it didn't work
 with wicket 6.11. I wanted to use the latest wicket for the new project.

 I also tried without seam-wicket in the classpath, but it also didn't help

 I feel like having tried all possible classpath combinations but none of
 them worked.
 I also debugged the initialization of weld at startup but couldn't detect
 the problem.

Re: wicket conversation scope - weld integration

[francois meillet]

your weld related jars in classpath should be:

wicket-core
cdi-api
seam-conversation-spi
wicket-cdi

 Hello François,

 thanks for your reply!
 I double checked this.
 I have weld-servlet.jar in my classpath. According to the documentation
 this
 is the ueber-jar that contains all classes of other jar files. I belive
 so
 because otherwise i get NoClassDef-Errors.

 i changed my classpath and removed wicket-weld according to heapifyman.
 No my weld related jars in classpath are:

 weld-servlet.jar
 seam-conversation-spi-3.0.0.Final.jar
 seam-conversation-weld-3.0.0.Final.jar
 wicket-cdi-6.11.0.jar

 i cannot imagine where a second weld implemention could reside?

 the rest of my configuration:
 web.xml:

  listener


 listener-classorg.jboss.weld.environment.servlet.Listener/listener-class
 /listener

 beans.xml (in WEB-INF- Folder):

 and my context.xml looks like this:

 Context path=/sandbox reloadable=true

 docBase=C:\develop\workspaces\1H_ASPWicketSandbox\ASPWicketSandbox\WebContent
 workDir=C:\develop\workspaces\1H_ASPWicketSandbox\ASPWicketSandbox\work 
 Logger className=org.apache.catalina.logger.SystemOutLogger
 verbosity=4 timestamp=true/
 Loader className=org.apache.catalina.loader.DevLoader
 reloadable=true
 debug=1 useSystemClassLoaderAsParent=false /
  Resource name=BeanManager
   auth=Container
   type=javax.enterprise.inject.spi.BeanManager
   factory=org.jboss.weld.resources.ManagerObjectFactory/

Re: Problems with FileUploadFile and CompoundPropertyModels

[Francois Meillet]

FileUploadField needs a model which implements IModelListFileUpload

 Hello, I'm having a problem with a FileUploadField, I'm using 
 CompoundPropertyModels through my application but for this single element I 
 would like to avoid having a model, however calling 
 fileUploadField.setDefauiltModel(null) will not work, since it will always 
 try to locate a CompoundPropertyModel, is there a way to avoid this?
 
 Thanks in advance.
