Re: Dateparsing error kendo AjaxDateTimePicker only in March, May, October
That solved the problem, thank you Sebastian! By he way, when I use E in my date pattern, like in " d ", that still doesn't work. When the datetimepicker is displayed first, it renders ok: dinsdag 1 maart 2016 (dinsdag=tuesday, maart=march in Dutch) But when I change the date, I get: Error while parsing datetime: date was ' 17 maart 2016' and time was '19.00' -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Dateparsing-error-kendo-AjaxDateTimePicker-only-in-March-May-October-tp4673756p4673779.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: Dateparsing error kendo AjaxDateTimePicker only in March, May, October
It's a Locale thing...
I Have:
@Override
public Locale getLocale() {
return new Locale("nl", "NL");
}
When I change this to ("en", "US") it works fine for me too.
And I discovered another thing: the dutch short, three letter forms for
months are the same as in English, except for March, May and October ('mrt',
'mei', 'okt' versus 'Mar', 'May' and 'Oct'), which explains the odd
behaviour I mentioned in my first post.
Perhaps Dutch is not supported for this kind of GUI translations?
I'd rather not change to the English Locale.

Re: Dateparsing error kendo AjaxDateTimePicker only in March, May, October
It's not a DatePicker, but a AjaxDateTimePicker.
I discovered it is indeed a pattern issue.
This is my code:
private final static String dateDisplay = "dd MMM ";
private final static String timeDisplay = "HH.mm";
scheduleDateTimeField = new AjaxDateTimePicker("scheduledatumtijd",
planDateModel, dateDisplay, timeDisplay) {
etcetera.
It works when I change dateDisplay to "dd MM ", so that the month parses
to a two digit number in stead of a shortened String (like 'Mar', 'Apr'...).

Re: HomePage reloads on every Ajax submit
I figured it out, it wasn't a Wicket thing. Someone changed our script for setting up an application server in Eclipse WDT, making it ssl-only (secure cookie).

Infomessage ExternalLink in case of a missing URL
Hello to y'all,
I'm facing a nasty problem for a very simple requirement. In my application
a user can enter an application code for working with that application
(deployments and so on).
Now I want to add a button that opens a Wiki-documentation page for that
application in a new browser tab. The URL for the wiki-page is stored in the
same database table as is the application code. I implemented this at first
with an ExternalLink, but I want to show an information message if the URL
is not entered in the database.
I can't get that done with an ExternalLink, so I used a Link instead. Well,
that gives the possibility to display info messages, but then I have to open
the URL myself by something like:
public void onClick() {
String docRef = getRefFromDb();
if (docRef == null) {
info("Please supply wiki-url first");
return;
}
RedirectRequestHandler redirectRequestHandler = new
RedirectRequestHandler(docRef);
RequestCycle.get().scheduleRequestHandlerAfterCurrent(redirectRequestHandler);
}
Obviously I leave my page when the link is clicked, so I added
onBeforeRender() in which I add PopupSettings if the url is found, so at
least I have a new window for the wiki-page (but I want a new tab). And if
not, I have to nullify the PopupSettings...
This is very awkward.
Please, anyone, a simple solution?
Btw, I'm (still) using Wicket 1.5.4.
Regards, Hans

if (condition) {

} else {
activate JS-popup-opener
}
And furthermore, I need to pass data to the popup-page, so I would have to
stick that in the Session?

This doesn't work. The condition has to be checked every time the link is
clicked, so within the onCLick().
setPopupSettings(null) gives the current page as popup.
Maybe this information is relevant: The link is part of a row in a repeater
(within the populateItem of a ListView).

setResponsePage(thePopupPage);
}
};

Re: Wicket and JPA: please a simple way to go
Tom, I couldn't agree more, you hit the spot. Indeed it's all about balance, don't over- (nor under-)architecture things. My application will be used by maybe 5 people, and requires some very simple CRUD-implemetations on a database table with maybe 100 rows (eventually). Here's what I will do: stick the EntityManagerFactory in the WicketApplication's subclass as Igor suggested (OK, without injection, but never use injection for injection's sake); same goes for UserTransactions for the CUD-part; make a DatabaseFacadeThing with all the necessary actions; that thing uses the WicketApplication's subclass and will be used by the Wicket components when needed. As a matter of fact, I already did make it, and it works fine. And there's only the JPA-obligatory persistence.xml, no other configs, components, and whatsoever. Igor, thanks again for your 'dry swum code sample'. Btw: em.close() is not allowed in a container-managed entity manager (JPA 5.9.1). For all the other suggestions (not JPA): thank you, I will look at them, just out of curiosity, because my company is a big, fat, obese insurance company, and big, fat, obese creatures don't move a lot and don't like to move. So it is JPA, and it will be so for ever and ever, in line with the company's daily definition of 'ever and ever'.

Re: Wicket and JPA: please a simple way to go
Igor, Josh suggested CDI as an alternative, in that respect it's the same as other approaches I've tried: to cumbersome, to complex for my goals, so in respect to what I want I don't think it's great. I'll look into the wicket-jee module in wicketstuff, but it is yet another extra 'thingy' you need for something that's so simple and basic... I wonder if anyone has ever coined the phrase 'boiler plate xml' or 'boiler plate components'. Maybe a quiz is a good idea. The Question is: fetch one row from a straightforward table in let's say an onclick of a wicket button, using jpa.

Re: Wicket and JPA: please a simple way to go
I looked at it, shortly. It's a perfect example of what I mean. I looked at a blog by Igor V. And there we go again: you have to do this; and than that. And then configure this. And don't forget to add a line in xml. And in the end, put it all together and it's so great. I don't think so. I think JPA has to make life easier, and it does for me when I'm not using Wicket: inject an EntityManager and do my db-stuff. That's how it should be, IMHO.

Re: Error 404: File not found: /bookmarkable/org.apache.wicket.markup.html.link.PopupCloseLink$ClosePopupPage
Just to get this out of my system: I spent hours and hours and hours trying
to solve this (Error 404: File not found:
/bookmarkable/org.apache.wicket.markup.html.link.PopupCloseLink$ClosePopupPage).
Nobody could help me here. Tried a quickstart, couldn't reproduce it there,
so obviously in my specific case Wicket decides to go left at some austere
point where it should go right.
And my usecase is so simple: press a button that closes a PopupPage. And it
worked fine in some older Wicket version.
This is so frustrating. Another example. Just this week I upgraded to Wicket
1.5.4, and all of a sudden all my Dropdownboxes generated warnings and
behaved differently (not showing the wright default value). I fixed this,
but again it cost me a lot of time.
And the 404... In the end I fixed that too:
public class WindowClosingButtonThatRealyWorks extends Button {
private static final long serialVersionUID = -8141558420171531381L;
public WindowClosingButtonThatRealyWorks(String id, IModel
model) {
super(id, model);
addClosingBehaviour();
}
private void addClosingBehaviour() {
this.add(new AttributeAppender("onclick", new
Model("window.close()"), ";"));
}
}

Re: Event or Notice when a ListView's Model changes
But when the event is processed, I'm not in an AjaxRequest.
Anyway, I have something working, now, I am able to update a version field
(by sending an inter-component event in the onBeforeRender() of the
ListView that has it's own Form; the Event is processed by another Form at
the top of the same Panel - that's where the version field is), but I still
need an AbstractAjaxTimerBehavior - now at 3 seconds - to make the updates
visible for the user. That worries me, I would like to have an update
interval of a second, or even less, but I wonder if this is wise. My
solution now on the receiving side looks something like:
add(new AbstractAjaxTimerBehavior(Duration.seconds(3)) { // add to the Fom
@Override
public void onEvent(Component component, IEvent event) {
if (event.getPayload() instanceof ProcessReadyNotfication) {
==> Update VersionField
super.onEvent(component, event);
}
}
@Override
protected void onTimer(AjaxRequestTarget target) {
// This can take up to 3 seconds!
target.add(VersionField);
}
});
Of course, I would like something like:
@Override
public void onEvent(Component component, IEvent event) {
if (event.getPayload() instanceof ProcessReadyNotfication) {
==> Update VersionField
target.add(VersionField);
super.onEvent(component, event);
}
}
But I don't have a AjaxRequestTarget there, and obtaining one by
AjaxRequestTarget.get() causes an IllegalStateException (As far as I can
remember).

I'm sorry if my writing is confusing. But there isn't a label that outputs the state, because the list shows /only/ finished processes.

Re: Event or Notice when a ListView's Model changes
But the List isn't updated by a user's action. There's a decoupling here: the user's action inserts a row that has a 'state-column' that's initialized with, let's call it 'unfinished'. The processes are executed asynchronously by another thread, that, after some minutes, updates the state-column to 'finished'. My ListView represents a list of finished processes, so you can never know when the selection on the database changes. So how do I know when an update has taken place?

Re: Migrating a ResourceStreamRequestTarget to a ResourceStreamRequestHandler (2)
Hello, Yes, I did, realizing that it's a bit of a coarse solution. As it happens, my application main function is to execute scripts for automated deployment on a WebSphere platform, so users work with a JEE-application they select from a wicket Ajax-textfield with application build versions that's connected with our Nexus repository (that at it's turn is populated with Maven-builds by Hudson). So, these users want to download builds, installation manuals, reports, and the like for inspection and reference. As a result, /any/ download is dynamically created at runtime, so there is no wish for caching, on the contrary, and it's not to be expected that it will be. Nevertheless, I will delve into the org.apache.wicket.request.resource.AbstractResource.ResourceResponse#setCacheDuration, because I like fitting solutions, and not over-sized ones: I tend to believe that that is what you are hinting at in your reply. I just have to figure out how the setCacheDuration can be applied to the AbstractResourceStreams that I use.

Migrating a ResourceStreamRequestTarget to a ResourceStreamRequestHandler (2)
I managed to pinpoint my issue. I'm starting a new topic in order to exclude
information I
now think isn't relevant anymore.
I don't think it's a caching problem any longer, but that is has to do with
a hanging
thread or something that's not closed properly, that is, when using Firefox
and Chrome.
In IE8: no problems, works as it did in 1.4.18 with the Wicket
ResourceStreamRequestTarget.
My code again:
Link downloadInstallationmanualButton = new
Link("downloadinstallationmanual", new Model()) {
@Override
public void onClick() {
if (user didn't supply any data) {
info("Please supply this and that");
return;
}
//create an subclass of AbstractResourceStream called
InstallationManualResourceStream
InstallationManualResourceStream theInstallationManualResourceStream
= new InstallationManualResourceStream();
if (theInstallationManualResourceStream.manualNotfound) {
info("No manual found for your input");
return;
}
ResourceStreamRequestTarget resourceStreamRequestTarget = new
ResourceStreamRequestTarget(
theInstallationManualResourceStream,
theFileName);
RequestCycle.get().setRequestTarget(resourceStreamRequestTarget);
}
(The underlying InputStream is closed properly, even in Firefox.)
The problem is in the last statement:
/RequestCycle.get().setRequestTarget(resourceStreamRequestTarget);/
This statement causes something to hang, so that in a new RequestCycle, the
onclick() isn't
fired anymore (and never again). When I omit this statement, the onClick()
fires each time.
I don't think I'm doing something wrong, certainly not after I discovered
that it works in IE8.
Maybe this is relevant: the underlying InputStream is part of a
ZipInputstream. Bij 'newing' my
InstallationManualResourceStream, the ZipInputStream is read until an
installation manual is found (hence
the /theInstallationManualResourceStream.manualNotfound()/ and it's info
message),
and then 'handed over' to the Wicket AbstractResourceStream.

Re: Migrating a ResourceStreamRequestTarget to a ResourceStreamRequestHandler
I will try these suggestions, but I't is quite frustrating that migrating
such a simple function causes so much problems.
In the meanwhile, I read the improvements in the caching mechanisms of
Wicket 1.5 on
https://cwiki.apache.org/WICKET/caching-in-wicket-15.html
It says:
/Caching is uniformly disabled now by sending the following HTTP response
headers:/
So I tried:
HttpServletResponse response =
(HttpServletResponse)getResponse().getContainerResponse();
response.addHeader("Pragma", "no-cache");
response.addHeader("Cache-Control", "no-cache, no-store");
response.addHeader("Expires", "Thu, 01 Jan 1970 00:00:00 GMT");
at various places.
I also put
((WebResponse) getResponse()).disableCaching();
in the body of the onClick,
But Firefox is still caching like a madman!!

Migrating a ResourceStreamRequestTarget to a ResourceStreamRequestHandler
I'm experiencing strange behaviour in migrating a ResourceStreamRequestTarget
to a ResourceStreamRequestHandler.

be downloaded
depends on the user's input. In some cases there isn't a manual, and so I

solution was a Link with
an onClick. in pseudocode:
Link downloadInstallationmanualButton = new
Link("downloadinstallationmanual", new Model()) {

public void onClick() {
if (user didn't supply any data) {
info("Please supply this and that");

IResourcestream theInstallationManualResourceStream = new
InstallationManualResourceStream();
if (theInstallationManualResourceStream.manualNotfound) {
info("No manual found for your input");
return;
}
ResourceStreamRequestTarget resourceStreamRequestTarget = new
ResourceStreamRequestTarget(
theInstallationManualResourceStream,
theFileName);
RequestCycle.get().setRequestTarget(resourceStreamRequestTarget);
}
As I mentioned, this worked perfect.
As part of the migration to Wicket 1.5.(2), I replaced the last two
statements by:
ResourceStreamRequestHandler resourceStreamRequestHandler = new
ResourceStreamRequestHandler(
theInstallationManualResourceStream,
theFileName);
RequestCycle.get().scheduleRequestHandlerAfterCurrent(resourceStreamRequestHandler);
When I click on the button after a server restart and opening of a fresh
browser, the onClick isn't
executed. Instead, the browser's (FireFox) save or open popup occurs, with
download-data of the
Session before the server restart, a sort of browser caching?
Only when I have pressed the browser's refresh (F5) twice, the onclick is
executed.
After that, it never executes again, and so the IResource isn't updated.
Shouldn't the onClick always be executed?
What am I doing wrong?
Thanks in advance, Hans Friederichs

Re: MIgration to 1.5.2 seems a disaster
I'm sorry, but my initial question was how to debug my migrated application. No matter what I do - for example I commented vast amounts of code, to reduce the scope of the problem - nothing works. One click: [ERROR] 2011-11-05 20:07:10 org.apache.wicket.request.cycle.RequestCycle:314 - Error during processing error message java.lang.IllegalStateException: Header was already written to response!

MIgration to 1.5.2 seems a disaster
Hello, I am trying to migrate from 1.4.18 to 1.5.2. I followed the suggestions on https://cwiki.apache.org/WICKET/migration-to-wicket-15.html I have a Wicket application with 6 tabs. After starting the server and a browser-instance, I get: [ WARN] 2011-11-05 17:00:26 org.apache.wicket.request.handler.render.WebPageRenderer:162 - The Buffered response should be handled by BufferedResponseRequestHandler. Just that. Then, on every action I try (click something, check a radiobutton), I get: [ERROR] 2011-11-05 16:51:51 org.apache.wicket.DefaultExceptionMapper:114 - Unexpected error occurred java.lang.IllegalStateException: Header was already written to response! at org.apache.wicket.protocol.http.HeaderBufferingWebResponse.checkHeader(HeaderBufferingWebResponse.java:64) at org.apache.wicket.protocol.http.HeaderBufferingWebResponse.sendRedirect(HeaderBufferingWebResponse.java:112) at org.apache.wicket.request.handler.render.WebPageRenderer.redirectTo(WebPageRenderer.java:136) at org.apache.wicket.request.handler.render.WebPageRenderer.respond(WebPageRenderer.java:266) And it keeps spawning these stacktraces... Furthermore, as might be expected form an 'Unexpected Error', there's no clue to the origin of this Exception in my application. Using development mode doesn't add information. When I don't try to do something on the opening tab, and choose another tab, I get: org.apache.wicket.request.handler.ComponentNotFoundException: Could not find component etcetera Everything worked perfect with Wicket 1.4.18, and now nothing does. Please, where do I start? Many thanks in advance -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/MIgration-to-1-5-2-seems-a-disaster-tp3993637p3993637.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: I just want the entered value of a WIcket DateTimeField...
I'm not sure what you mean by the popup being a separate issue, it is what my usecase is all about, a download of a dynamically created excel-file, for which I need a fromDate... Anyways, it surprise me that this is so complex, that there isn't a straightforward solution. I spend many hours trying to solve this. Thank you for your advice, but please could you - or anybody else - be more specific in providing a way to go?

Re: I just want the entered value of a WIcket DateTimeField...
Hello Martin,
I tried that, but at the end of the link's onClick there's the code to
download the excel-file:
IResourceStream resourceStream = new AbstractResourceStream() {
(all the necessary stuff here
};
String fileName = "DeployView.xls";
ResourceStreamRequestTarget resourceStreamRequestTarget
= new ResourceStreamRequestTarget(resourceStream, fileName);
RequestCycle.get().setRequestTarget(resourceStreamRequestTarget);
When I use an (ajax)button, the browser's download-screen (save or open)
doesn't pop up...

I just want the entered value of a WIcket DateTimeField...
Goodday,
I'm working on an Panel that has one function: downloading an excelsheet
that is a view to a database.
IN constructing the excel-sheet, I need a fromdate for a whereclause. There
are other clauses, but for simplicity's sake:
In a Wicket Form I have one DateTimeField fromDateTimePicker,
and one Link downloadSpreadsheetButton:
fromDateTimePicker = new DateTimeField("vanafdatumtijd", new Model());
fromDateTimePicker.setOutputMarkupId(true);
fromDateTimePicker.setModelObject(new Date());
add(fromDateTimePicker);
downloadSpreadsheetButton = new Link("download_spreadsheetbutton",
new Model()) {
private static final long serialVersionUID =
9179702662683794429L;
@Override
public void onClick() {
Date picked = fromDateTimePicker.getModelObject();
SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-
HH:mm");
System.out.println(sdf.format(picked));
}
};
downloadSpreadsheetButton.setOutputMarkupId(true);
add(downloadSpreadsheetButton);
No matter what I try, I never get the entered date, always the initial date.
I suspect that the datetime-model isn't updated because there is no
form-submit (?).
Please help.
Regards, Hans

Re: How to Handle ResourceStreamNotFoundException
Hi Dan, This is /exactly/ what I was looking for! A simple solution for a simple problem. I used a (subclass) of a WebResource before for another use case, and that worked fine, so I got blinded by wanting to reuse the same solution, at least that is what I think has happened. Whatever. Thank you very much for your interest and help.

Re: How to Handle ResourceStreamNotFoundException
Firstly, thank you very much for your advice, it helps to a certain extend, but it also raises new questions. Unfortunately, there's only one way to determine whether a zip-file contains an installation manual. Since the zip-file is on another server (where the nexus repository resides), I have to read it from an InputStream. If there isn't an installation manual, this reading can take up to 10 seconds. Initially - when there's not a user entry yet, I can disable the download-button. But once an application code is entered, I only render meta information from all the zip-file versions, so the user can pick a desired version (usually the most recent build). Only when the form is submitted, or the new download button pressed, the corresponding zip-file is read, and only then I can determine whether it contains an installation manual. But I have to enable the button if there is a user entry. That can be a very disapointing user experience. He/she starts the appication, the button is disabled. He/she then enters an application code, en presses the now enabled button, only to find out that there isn't an installation manual... One question that comes to mind is: is my use case so exceptional? A button for a resource is pressed, all I want is a nice feedback in case a resource isn't available... Personally, I'm not a great fan of disabling or 'invisibling' buttons. I adhere to the five-year-old-boy-philosophy concerning buttons: you should /allways/ be able to press them, that's what buttons are for. Your alternative (using the RestartResponseException) solves the 'white screen-problem', but there are a few drawbacks: - The URL of my application after pressing the button changes from http://localhost:9081/deploy/ to http://localhost:9081/deploy/?wicket:interface=:3:deploytabs:panel:deployForm:downloadinstallationmanual::IResourceListener::. I really like Wicket, but this is so annoying. Who wants this? I just want my original url back - and yes, I read all the posts on mount strategies. - What's worse, the user has entered an application code that generates other field values (like a dropdownlists for the versions). When the page is reloaded after a RestartResponseException, I want to initialize it with the afore entered data. I managed to do that using PageParameters (or the Session), but in that case the refresh button will always generate a 'prefilled' page, with the values of the lat entered application code.

How to Handle ResourceStreamNotFoundException
Hello to you all,
First of all, I apologise for submitting this post for the second time, but
the first didn't use the correct user group.
I'm adding a new feature to a Wicket application that manages
JEE-applications (I'm using 1.4.18). For example, it's possible to install
and configure a JEE-appliation on an Application server. If a user chooses
to do so, he enters a unique application code and submits: a zipfile
containing the application, it's documentation and configuration is
downloaded via http from a Nexus repository, and installed with
soap/jmx/mbeans on the application server.
What I have added, is a button that - once clicked - opens an installation
manual in msword that is part of the aforementioned zipfile. The general
idea is: take a zipinputstream, read it until the installation manual is
found, then hand the inputstream over to a wicket IResourceStream that
provides the getInputStream for a Wicket WebResource. I think it's a quite
elegant solution; it's all streaming, no temporary files etcetera.
And it works marvelously, that is, if the zipfile actually containes a
installation manual. My problem is twofold:
When pressing the button without entering an application code (so there is
no inputstream and no installation manual) wicket produces:
org.apache.wicket.WicketRuntimeException: Could not get resource stream
at org.apache.wicket.Resource.init(Resource.java:217)
at org.apache.wicket.Resource.onResourceRequested(Resource.java:117)
at
org.apache.wicket.markup.html.link.ResourceLink.onResourceRequested(ResourceLink.java:108)
... 36 more
That's to be expected, but the user is confronted with a white screen, and I
can't catch this Exception.
Secondly, if there is a zipinputstream, but no installation manual found in
it, all I can do is throw a ResourceStreamNotFoundException (see my code
below), but then again, I can't catch it, and again there is a white screen
for the user.
What is need, I think, is to override onResourceRequested() in Resource, but
that is a final method... And the onclick happens after
onResourceRequested()...
So what I want, is to handle the ResourceStreamNotFoundException in a
user-friendly way, by showing an info or error message in the wicket
feedbackpanel.
The code:
(So the user enters an application code an presses the new button:)
The button is counterparted by a ResourceLink in a Wicket-Form:
private Link downloadInstallationmanualButton = null;
...
final InstallationManualWebResource installationManualWebResource = new
InstallationManualWebResource(this);
installationManualWebResource.setCacheable(false);
downloadInstallationmanualButton = new
ResourceLink("downloadinstallationmanual",
installationManualWebResource);
downloadInstallationmanualButton.setOutputMarkupId(true);
add(downloadInstallationmanualButton);
The above mentioned
InstallationManualWebResource is a subclass of WebResource, and overrides
the usual methods:
@Override
public IResourceStream getResourceStream() {
installationManualResourceStream = new
InstallationManualResourceStream(getZipInputStream());
return installationManualResourceStream;
}
@Override
protected void setHeaders(WebResponse response) {
super.setHeaders(response);
if (installationManualResourceStream.getInstallatieHandleidingName()
!= null)
response.setAttachmentHeader(installationManualResourceStream.getInstallatieHandleidingName());
}
At it's turn InstallationManualResourceStream implements IResourceStream:
In it's constructor, the zipinputstream is read until an installation manual
is found. If so, a boolean installationManualFound is set to true, and
file-attributes are set (name, size, time). The implementation is
straightforward:
@Override
public void close() throws IOException {
zipFile.close();
}
@Override
public String getContentType() {
return "application/msword";
}
@Override
public InputStream getInputStream() throws
ResourceStreamNotFoundException {
if (!installationManualFound) throw new
ResourceStreamNotFoundException("No installation manual in zipfile");
return zipFile;
}
@Override
public Locale getLocale() {
return new Locale("nl", "NL");
}
@Override
public long length() {
return size;
}
@Override
public void setLocale(Locale locale) {
}
@Override
public Time lastModifiedTime() {
return Time.milliseconds(time);
}
