Re: Browser file download complete callback
hmm, seems like a bug. it looks like we now close the input stream
directly instead of using close() which allows users not to have to
keep a reference to the stream. #close() can probably be removed.
please open a jira issue.

Hi!

My problem is that I would like to be notified when the user is finished
downloading so that I can mark the downloaded item as downloaded in my

to do this by overriding the close() method. However, the close method of
the AbstractResourceStream never seems to be called.
The implementation of the getResourceStream() method of my WebResource
object:
public IResourceStream getResourceStream() {
return new AbstractResourceStream() {
ByteArrayInputStream bais;
public InputStream getInputStream() throws
ResourceStreamNotFoundException {
bais = getByteArrayInputStreamFromDB();
return bais;
}
public void close() throws IOException {
bais.close();
markByteArrayAsDownloadedInDB();
}
};
}
Why is it that the close() method is never called? Is there a better/other
way to do it? Is it at all possible to get a callback when a user is
finished downloading the bytearray?
Thanks in advance!

Re: Browser file download complete callback
Thanks for the reply!
So you're suggesting that the close() method of the IResourceStream should
be removed?
Isn't there a point in having the close() method? In my case, by overriding
the close() method, it would be possible to be notified when a download is
complete. Don't know how else I would accomplish that (any suggestions?).
Wouldn't it be a better idea to implement a close() method with default
close behaviour in the abstract classes implementing the IResourceStream
interface? That way, by extending one of these abstract resource stream
classes, you dont have to mind about the close() method if you dont want to.

Re: AjaxFallbackButton and setDefaultFormProcessing(false)
you could try nesting two forms - the inner form would then be the username
that gets submitted by the ajaxbutton.
if you then submit the outer form eventually the inner form gets resubmitted
as well ... AFAIK
and in case you're wondering: wicket supports nested forms (HTML doesn't)
and converts the inner form into a div ...
hope that helps,

I'm building a registration page for my wicket app, and I'm having trouble
getting an AjaxFallbackButton to work the way I would like it to. I have
several fields for the user to fill out on my registration page, including
email, password, desired-username, etc.
What I want is to have an AjaxFallbackButton next to desired-username to
see if it is available and then display a label saying whether it is or
isn't available. This works fine when AjaxFallbackButton's
setDefaultFormProcessing is set to true (as by default). However, this
runs the onSubmit() of the form, not just the onSubmit() of the button
itself as I want it to.
If I do ajaxFallbackButton.setDefaultFormProcessing(false) then it gets
nothing from the model.
When I have used non-Ajax buttons in the past with Wicket, I called
textField.updateModel() and then called textField.getModelObject(), which
made it possible to retrieve values with defaultFormProcessing set to
false and therefore did not run the form's onSubmit() method. However
when I do this with AjaxFallbackButton I get a null pointer execption :(.
If this is too incomprehensible, I can try to make a quickstart
demonstrating the problem. I'm really not sure what appropriate behavior
with these forms/buttons is to begin with though, so I would really
appreciate help. I have pasted my class which may help.
Thanks!

Re: How does serialization work?
I had a serialization problem (when redeploying the application in
Tomcat) that I can't understand... Basically, I had this on my
Page.onBeforeRender:
---
visitChildren(TextField.class, new VisitorTextField?() {
private static final long serialVersionUID = 1L;
public Object component(TextField? textField)
{
textField.add(new AjaxEventBehavior(onchange) {
private static final long serialVersionUID = 1L;
@Override
protected void onEvent(AjaxRequestTarget target)
{
if (mode == Mode.NAVIGATE)
{
mode = Mode.EDIT;
setupMode();
target.addComponent(buttonPanel);
}
}
});
setupValidators(textField);
return IVisitor.CONTINUE_TRAVERSAL;
}
});
---
The non-serializable class was the one created by new
VisitorTextField? () { ... }. Creating MyVisitor and replacing this
call solved the problem:
---
private abstract class MyVisitorX extends Component
implements IVisitorX, Serializable
{
private static final long serialVersionUID = 1L;
}
---
Why should a non-serializable Visitor could case this problem? Does
(why?) it get cached on the page?

Re: PageParameters in wicket 1.2.7 problem
This is what the 1.2 javadoc says about it:
protected WebPage(PageParameters parameters)
Constructor which receives wrapped query string parameters for a
request. Having this constructor public means that your page is
'bookmarkable' and hence can be called/ created from anywhere. For
bookmarkable pages (as opposed to when you construct page instances
yourself, this constructor will be used in preference to a no-arg
constructor, if both exist. Note that nothing is done with the page
parameters argument. This constructor is provided so that tools such as
IDEs will include it their list of suggested constructors for derived
classes.
So passing it down should not make any difference.
I've solved the problem using the cookies tip by the way, thanks for the
help.

I'm reading up on the session sharing, but from what I can see that is not

Hi Nino,
I don't link to the verification page from inside the application itself.
Instead, the link is send in an email to the user when he changes his email
adress. When they click the link, the page is opened. In a lot of cases the
users are still logged in on the application, meaning that a second tab is
opened. If that is the case, the url changes in the way that I described. If
there is no other tab with the application open when the user clicks the
link, the page works fine (meaning that the page parameters are being read).
Also, when the bug occurs it triggers an error message which tells that the
given code is incorrect, which means that the page parameters are read at
that point as well.

Hi Rik
Im not sure about this, it's been some months(if not years) since i've

instantiate the page with an other constructor..
Rik Overvelde wrote:
Hey everyone,
I'm having a problem with page parameters in wicket 1.2.7 when multiple
tabs are opened. I'm working on a verification system for email adresses,
which sends a mail with an url containing a guid to a user. I've mounted the
page using a queryStringUrlCodingStrategy which results in an address like:
http://page.com/verificatie?code=0572f18d-a9b1-4b92-bb89-7243b9e35d24.
When the link is opened while you're already logged in though, wicket
changes the url while loading in something like this:
http://page.com/verificatie?code=%5BLjava.lang.String%3B%4087bf0bwicket:pageMapName=wicket-0
From what I understand, this is a known issue with wicket 1.2 and is
solved in wicket 1.3. The application I'm working on however is already
fairly large and because of time constraints it is impossible right now to
migrate to 1.3 so I'm looking for a workaround for this.
One thing that I've been thinking about is to have the verification
link point you to a non wicket servlet, which writes the guid to its
session, then forwards you to a wicket page that retrieves the guid from the
other servlets session. Is there a way to get the other servlets session in
wicket?
If anyone has another suggestions for getting around this problem I'd
love to hear it.
With regards,
Rik Overvelde

Re: How does serialization work?
thats simple
what you there create is an inner class in an inner class...
so your textfield has a ajax behavior that is an inner class fo the Visitor
inner class so that behavior has a parent reference to the visitor..
make that ajax behavior his own class and your problem is solved

The non-serializable class was the one created by new
VisitorTextField? () { ... }. Creating MyVisitor and replacing this
call solved the problem:
---
private abstract class MyVisitorX extends Component
implements IVisitorX, Serializable
{
private static final long serialVersionUID = 1L;
}

Why should a non-serializable Visitor could case this problem? Does (why?)
it get cached on the page?

RE: Wicket 1.4 and Wicketstuff/Dojo/DragAndDrop
My work was for the wicket 1.4 trunk 6 months ago. Some things have changed since then. Actually I'm stuck into converting a huge wicket 2.0 Application to 1.4. It's a pain! I think I will get back to the Dojo project in 3 weeks. Then I will try to build a version for current wicket 1.4 trunk. For former development I will no longer trust in wicketstuff projects.

Problem using UTF-8 and QueryStringUrlCodingStrategy
Hello, I'm trying to use UTF-8 as the default encoding in a web application using Wicket and Spring. Although everything seems to be working properly, I'm facing a problem when dealing with a page mounted using the QueryStringUrlCodingStrategy. The application configuration * The html pages include the meta tag meta http-equiv=Content-Type content=text/html; charset=UTF-8 / * getRequestCycleSettings().setResponseRequestEncoding() returns UTF-8 as the encoding * I've configured the Spring CharacterEncodingFilter as the first filter in the web.xml filter filter-namecharsetFilter/filter-name filter-class org.springframework.web.filter.CharacterEncodingFilter /filter-class init-param param-nameencoding/param-name param-valueUTF-8/param-value /init-param /filter filter-mapping filter-namecharsetFilter/filter-name url-pattern/*/url-pattern /filter-mapping The problem If I have a page mounted as: mount(new QueryStringUrlCodingStrategy(/search/feed, SearchFeedPage.class)); and, in another page, a link to that one: BookmarkablePageLink(feed, SearchFeedPage.class, theParameters); where theParameters include, for example, a parameter with the value día The link is correctly encoded (using UTF-8) but, once it is clicked, it is not correctly decoded. Is there something missed in the configuration? is it a bug? If, instead of using QueryStringUrlCodingStrategy I mount the page as: mountBookmarkablePage(/search/feed, SearchFeedPage.class); everything works correctly Thanks -- View this message in context: http://www.nabble.com/Problem-using-UTF-8-and-QueryStringUrlCodingStrategy-tp20325317p20325317.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Browser file download complete callback
another problem with close is that you would have to internally keep a
reference to the inputstream(), and what if getinputstream() was
called more then once because for example you are generating a xls, a
csv, and a png all at once...then your close() has to keep track of
multiple references?

Re: How does serialization work?
we still have a last x pages stored on disk. it is just not a number of pages but it is how many pages fit in the default window size of the file on disk (1 file per pagemap) by default it is 10MB per pagemap and 100MB per total session. so by default you can hold 10 pagemaps of 10MB after that least used pagemaps are cleared. johan On Tue, Nov 4, 2008 at 12:48 AM, Igor Vaynberg [EMAIL PROTECTED]wrote: it is cleaned up when the session expires. it used to be that we only kept X last pages in the store, but now that we use disc that seems to be redundant. -igor On Mon, Nov 3, 2008 at 4:08 PM, Graeme Knight [EMAIL PROTECTED] wrote: Hi.

Couldn't find the answers from Tapestry in Action (I'm sure they are there if anyone can point me at a page). You might want to have a look at Wicket in Action :--) 1) Exactly WHAT is getting serialized and where and when? The page, which includes its whole Component tree. 2) What are the main classes in the framework responsible for serialization that I can look at (I have the source)? I guess I am after understanding the flow of logic. I find it easiest to start from Session.requestDetached(). There you have page.getPageMap().put(page); = SecondLevelCacheSessionStore.put(Page) = DiskPageStore.storePage(String sessionId, Page page) and there's already stuff about serialisation. I'm sure that someone can give you a more scientific answer :) 3) What happens if I make userIdField and passwordField scoped to the constructor only? Is it common not to have them as member objects and why? (I've not tried this yet, just wondered). In here add( userIdField ); add( passwordField ); you add them as children of the constructed component. You can always access them for example with a visitor, if needed, and holding references to them makes it harder to replace them if needed (though it shouldn't be a problem if they won't be replaced).

Re: Handling exceptions during render
Alex Objelean wrote: Can you be more specific? What kind of unexpected runtime exceptions are you talking about? I don't think I understood you correctly. It could be anything.. NPE (probably the most popular), IllegalArgumentException and its descendants, ArithmeticException, ClassCastException, IndexOutOfBoundsException etc... or a wrapper for a checked exception. It can happen in the application code or can be thrown from library code. As for the reasons.. again there are lots of possibilities: invalid input, buggy code, invalid data received from 3rd party, unhandled edge case, unavailable resource, high load, etc. Any runtime exception thrown by the wicket is caused by a programming error... there is no sense to catch it without fixing the problem in your code. That sounds foolish to me, unless you consider any failure to handle any of the situations described above, to be a programming error. And I disagree a LOT more about the second sentence: usually when an application is launched, it already passed some kind of testing which found everything to be working well, and the application works well for a while, then an unexpected exception happens. These exceptions in production are very good friends of Murphy and tend to follow several laws, such as: - Whatever can go wrong will go wrong, and at the worst possible time, in the worst possible way - Every non trivial program has at least one bug - If you perceive that there are four possible ways in which something can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop - If the input editor has been designed to reject all bad input, an ingenious idiot will discover a method to get bad data past it So anyway, when (not if) the unexpected exception is thrown in production code, what would you rather have the users see (whether there are 10, 1000 or 1000 users)? A big internal error page? Or a mostly-working page, but with one part missing or showing an error message? Especially if access to that same page is required in order to fix the problem! -- View this message in context: http://www.nabble.com/Handling-exceptions-during-render-tp20301737p20327592.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Moving from Tapestry to Wicket?
Honestly in our application (we have a roadmap for scalability) we are likely to get several hundred concurrent sessions per server with a few kb of state stored in the HTTPSession. Its not that much. That's definitively no problem for even a very modest setup. What I was more concerned about was Page storage and storage that I can't control (for example, if I couldn't control IModel storage I would be concerned). Well, when using any framework that abstracts stuff for you, you'll trade convenience for transparency. I believe Wicket's architecture is very open and it is easy enough to customize how it works for what you want, but the more you want to deviate from the default, the more work it'll be. I think you should just build the darn thing and optimize when you have proof (through load testing for instance) that you are hitting a bottle neck. :-) Do try to work with detachable models (LoadableDetachableModel is my favorite) where you can, because that will save considerably especially with complex domain models and avoid lazy loading problems with frameworks like Hibernate. We are unlikely to have spikes of traffic, but we are more likely to have dribs and drabs of users who potentially keep sessions open for perhaps minutes to hours. Not a problem at all. For our initial scaling the client will have an affinity to a specific server. We can control the number of users that we have on a server. We can then scale our servers horizontally if we hit a scaling issue on one of the servers. I'm starting not to worry about it too much. Yeah, with just a few hundred users clustering won't be much of a problem either. Once you start to hit tens of thousands of concurrent sessions you have to take this stuff more seriously, but until then in my experience you'll be tweaking your database and business logic etc way before Wicket gets to be in the way :-) Eelco - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Feedback/Error message.
Hey! Cool - add a feedback panel then set error - I like that! I didn't get to that part in the Wicket in Action as yet but I see how it works! Actually - my authentication method is very similar to the one on the book (again not got to that part yet), so I'm pretty psyched I'm heading in the right direction! I'm assuming if I wanted a panel with an icon and an error message I just create a component with a feedback panel and an image and populate accordingly?

Re: Moving from Tapestry to Wicket?
Hey Eelco! Awesome! Thanks for your answers - they really helped. I appreciate the time. BTW, Wicket in Action is a really well written book compared to others in the genre. Thanks to you and Martijn for the hard work! It came at the right time for me and we have decided to make the move from Tapestry. Let you know how it goes, and I'll be on the forums plenty I am sure!

Question about property expressions
Hi all,
if I have a class like this:
class SomeClass {
String getValue(String key);
}
...is there a way I can use a property expression to get values out of this
class? E.g. using an expression like value[myKey].
In other words, something very similar to if the class looked like this:
class SomeClass {
MapString, String getValues();
}
(of course, the expression would be values[myKey] in this case)
Unfortunately, in this instance the class isn't one that I can change. So,
is the former example possible with the property expressions that come with
Wicket? If not, what is the easiest way to extend these to do what I want -
overriding AbstractPropertyModel.getObject()?

Jan

Slogging through Wicket's guts
I'm trying to understand how Wicket's RequestCycle works in order to resolve the problem I explained in my previous post, Losing session information. I'm using Eclipse's debugger to step through the process, but I've hit a wall. I'm using Wicket 1.3.4, and I get stuck at RequestListenerInterface, line 183. At this point, Wicket calls method.invoke(..). The object method has IFormSubmitListener as its class and onFormSubmitted as its method name. This is apparently an important line, since it's the place where the submitted form values get transferred from the request to the session.

Looking for an example of Remember-me login functionality
I'm hoping to find a working example of a remember-me type login. I don't mean that the username is stored in a cookie, but rather the user doesn't need to go to a login page as they are authenticated through cookies immediately. I have struggled to try and piece together the code from this example: http://swik.net/User:go4info/go4blog/wicket,+acegi+and+remember+me+authentication/bmcu1 Wicket-Remember-Me-Authentication But i have never been able to put the fragments together to make a working demo. Acegi and Auth Roles is the way I am currently authenticating, but I am willing to drop the entire combo if there is an easier way. It also worries me a little that every url is filtered through acegi when they don't all need to be, but thats a different discussion altogether. So if anyone has accomplished this, or knows of a place with more information I would greatly appreciate it. -- View this message in context: http://www.nabble.com/Looking-for-an-example-of-Remember-me-login-functionality-tp20334450p20334450.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Slogging through Wicket's guts
it uses reflection to invoke the proper methods. the contract of the listener interface is that they contain a single void method that takes no arguments, this method is then invoked on the component via reflection. so since form implements iformsubmitlsitener its onformsubmitted() method will be invoked. -igor On Tue, Nov 4, 2008 at 4:35 PM, danelav [EMAIL PROTECTED] wrote: I'm trying to understand how Wicket's RequestCycle works in order to resolve the problem I explained in my previous post, Losing session information.

Re: Looking for an example of Remember-me login functionality
this kind of code needs to go into your authorization strategy. there instead of redirecting to login page you first check for cookies and if the proper cookie is found simply return true instead of redirecting to login page. you can use (webrequest)requestcycle.get().getrequest() to get to cookies. -igor On Tue, Nov 4, 2008 at 4:40 PM, fatefree [EMAIL PROTECTED] wrote: I'm hoping to find a working example of a remember-me type login.

Re: Question about property expressions
Sure. To explain a bit more why I'm asking: I have a table component that's
configured using property expressions as to what's shown in each column.
The types of objects to be shown in the table are not known in advance,
hence having a hard coded model for a specific type of class isn't really
desirable. Given this, do you think it would make sense to provide an
extended property model, so that it could cope with the type of example of
objects I showed below?
Thanks,
Jan

no you cannot use propertymodel, but you can easily write your own
model that calls the method directly.

Hi all,
if I have a class like this:
class SomeClass {
String getValue(String key);
}
...is there a way I can use a property expression to get values out of
this
class? E.g. using an expression like value[myKey].
In other words, something very similar to if the class looked like this:
class SomeClass {
MapString, String getValues();
}
(of course, the expression would be values[myKey] in this case)
Unfortunately, in this instance the class isn't one that I can change.
So,
is the former example possible with the property expressions that come
with
Wicket? If not, what is the easiest way to extend these to do what I
want -
overriding AbstractPropertyModel.getObject()?

Jan

PropertyColumn and generics
I'm writing a custom BooleanChoiceFilteredPropertyColumnT extends ChoiceFilteredPropertyColumnT (on 1.4-m3). When implementing @Override public void populateItem(final Item cellItem, final String componentId, final IModel model) I get a warning about Item and IModel needing to be parameterized. Makes sense. But if I parameterize it, I get: Name clash: The method populateItem(ItemICellPopulatorT, String, IModelT) of type BooleanChoiceFilteredPropertyColumnT has the same erasure as populateItem(Item, String, IModel) of type PropertyColumnT but does not override itBooleanChoiceFilteredPropertyColumn.java So it turns out that even though Item and IModel have been generified (as well as PropertyColumn), the signature of populateItem in PropertyColumn is still: public void populateItem(Item item, String componentId, IModel model) Shouldn't that be: public void populateItem(ItemICellPopulatorT item, String componentId, IModelT model) , the way it is in ICellPopulator? Am I smoking or misunderstanding generics?

Re: Looking for an example of Remember-me login functionality
Thanks igor, I looked into that and unfortunately the method that controls that is declared final in auth roles' AuthenticatedWebApplication (public final void onUnauthorizedInstantiation(final Component component)) What I came to realize is that by configuring acegi's standard remember-me processing filter, acegi will take care of looking for a cookie and using it to authenticate. The problem seems to be in creating the cookie for the first time, since I don't see how I can use acegi (which traditionally uses authenticationProcessingFilter, that seems to be url driven) to hook into a successful authentication and create the cookie. So my plan to remedy that was to inject the remember me service into the application, and create the cookie after the submission of the login form. I'll experiment with that tomorrow and share my results. But i appreciate the feedback igor.vaynberg wrote: this kind of code needs to go into your authorization strategy. there instead of redirecting to login page you first check for cookies and if the proper cookie is found simply return true instead of redirecting to login page. you can use (webrequest)requestcycle.get().getrequest() to get to cookies. -igor -- View this message in context: http://www.nabble.com/Looking-for-an-example-of-Remember-me-login-functionality-tp20334450p20335335.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Design question : accessing components between panels
Hello , I have an application which renders a page. This page has two panels , panel A and panel B Each panel has some components in it. Now I want to access some component in panel B from panel A. Can someone tell me how do I get a handle to panel B in panel A ? If I have an instance of the page, then I can do a *get(id of panel B)* to get the instance of panel B But how do I get the instance of the home page in panel A ? How can I acheive this scenarion in the best possible way? Can someone please help me as I have lot of cases with these scenarious ? Regards, Arun Wagle

I'm not entirely sure what setAuto does, I hope it doesn't break anything in this case. What does that exception mean anyway?

adding favicon using behavior
Hi, We have a behavior that is added to our main page (we use markup inheritance). In the behavior we add CSS links (and JS). We want to add a favicon as well. Here's what we did: response.getResponse().write(link rel=\SHORTCUT ICON\ href=\/resources/favicon.ico\/\n); Is this the best way?
