Re: TabbedPanel and model load...
because I use the domain objects directly,. without any DTO's, I have to use
the long conversation pattern. That means I have to store the domain object
somewhere in the session and let the loadabledetachable model retrieve it
from there?

then you have to use a bean, and on confirm apply changes from the
bean to the persistent entity. the only other alternative i know of is
to use the long conversation pattern which i am not really a fan of.

no don't introduce a transient field for that. (its not serialized but in memory its an extra slot) We could that by using the same field and compress it in detach.

Re: TabbedPanel and model load...
The order has methods createMemento():Memento and applyMemento(Memento
m). These are used to get objects that contain state. They can in
turn be applied to the order to set it back to that state at a later
point. So yes, you fetch the Order, detach it, call applyMemento() if
you have unsaved work, make additional changes to the order, call
createMemento(), and then put that in the session.

ok. never used memento, so I picked the book and read about it. I'm not sure
how to implement this. When do I retrieve a memento from the order? And in

changes?
Or do I for each add/remove/change the user makes:
- load the original order,
- apply any memento's present in a temp space (session)
- apply new changes
- create a memento
- discard changes to DB
2008/2/11, Scott Swank [EMAIL PROTECTED]:
The order has one or more order mementos (pre/post editing) and each
order memento has a collection of orderline mementos. The mementos
are completely opaque, and only the Order OrderLine are able to
inspect them and extract their content -- perhaps by implementing them
a static inner classes with private mutators.

I suggest using the GoF memento pattern here. You keep your changes
in one or more mementos, which can be kept in the session. Then you
push the changes back to the domain model when you are happy with
them. We use this approach for modifying hotel reservations --
particularly because we need to see the price before the change as

Re: TabbedPanel and model load...
that sadness is an artifact of how hibernate works. it is
easier/cheaper to create a bean than keep a disconnected session in
your http session, which can be quiet memory intensive. of course
which way you go is up to you.
in a lot of these cases i have noticed that the mapping isnt always
1:1 between what is in the domain model and what is in the ui anyways,
so a bean also makes your ui code a lot leaner.
just my two cents.

wicket-security, everybodyprincipal and only securepages
Hi, I'm fiddling around with wasp and swarm. I was wondering if it is possible to add an EverybodyPrincipal to the current session on session instantiation. The problem is the following: I'd like to let my BasePage (from which ALL pages in my app inherit from) extend SecurePage to be able to control the actions for all pages with the hive file. But as a SecurePage requires an authenticated session, I can't let my basepage extend SecurePage. So I thought, that I could just add a subject containing an EverybodyPrincipal on session creation. I.e. in the session's constructor or in the application's newSession method, sothat the session gets authenticated behind the scenes and the page gets rendered fine. Unfortunately this results in a Stackoverflow as the Session.get() method calls the login method and vice-versa... so what's the best way to handle that? thanks in advance (to maurice i think ;-)) regards Michael - Michael Sparer http://talk-on-tech.blogspot.com -- View this message in context: http://www.nabble.com/wicket-security%2C-everybodyprincipal-and-only-securepages-tp15413102p15413102.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: wicket-security, everybodyprincipal and only securepages
I was wondering if it is possible
to add an EverybodyPrincipal to the current session on session
instantiation.
After reading your mail again, trying to recreate the stackoverflow, i
realize you said the EveryBodyPrincipal, the whole time i was reading
is as AllPermissions. :-s
The EveryBodyPrincipal is kind of strange in the sense that you do not
need to add it yourself to a user. It is automatically assigned to
every user if your policy contains one or more
grant
{
.
};
blocks. Note the absence of the principal class and name.
So please don't use it yourself :)

TabbedPanel tab names
Assuming the typical tabbed panel example below - is there a good way to
grab the tab name from the page's properties file? What I need to do is
to internationalize the tab name. I guess I could do my own call to grab
it from the classpath + the property file name. Was hoping
List tabs = new ArrayList();

Re: wicket-security, everybodyprincipal and only securepages
First off i would like to see your code as it should not be possible
to create a StackOverFlow.
Second i am not entirely sure why you would want EVERY page to be a secure page.
For instance the login page should not be a secure page, also the
first page a user hits after logging in (usually the home page) is a
candidate.
Anyway since you probably want every page to extend BasePage why not
have a subclass that implements ISecurePage and have all your pages
that should be secure extend that page.
For the implementation of ISecurePage you can simply redirect all
calls to the SecureComponentHelper.
Another option to grant permissions to every user is to put them in a
grant block without a principal like this:
grant
{
//permissions here
};
Note that you do need a logged in user for this to work.
If this is not what you are looking for then how about a little example.

Hi,
I'm fiddling around with wasp and swarm. I was wondering if it is possible
to add an EverybodyPrincipal to the current session on session
instantiation.
The problem is the following: I'd like to let my BasePage (from which ALL
pages in my app inherit from) extend SecurePage to be able to control the
actions for all pages with the hive file. But as a SecurePage requires an
authenticated session, I can't let my basepage extend SecurePage.
So I thought, that I could just add a subject containing an
EverybodyPrincipal on session creation. I.e. in the session's constructor or
in the application's newSession method, sothat the session gets
authenticated behind the scenes and the page gets rendered fine.
Unfortunately this results in a Stackoverflow as the Session.get() method
calls the login method and vice-versa... so what's the best way to handle
that?
thanks in advance (to maurice i think ;-))

Re: ModalWindow with Page memory leak
Hi, More information about this memory leak problem. This problem doesn't happen in version 1.3 (Development/deployment mode) and only happens in version 1.3.1 (development/deployment mode). Thanks. Regards Boon Ping. On Feb 12, 2008 7:36 AM, Henrik Lundahl [EMAIL PROTECTED] wrote: Hi, In my current project we have a page with six AjaxLinks that open different ModalWindows. We had implemented sub-classes of ModalWindow which had field references to the content Pages (the source of the iframes in the ModalWindows) created by ModalWindow.PageCreators. The references were there to extract state from the Pages when the ModalWindows were closed. The Pages also had field references to the ModalWindows in order to call close on them. Using this design, the serialization/deserialization increased seemingly exponentially for every opened and closed ModalWindow, causing a gigantic memory leak. After opening and closing a number of ModalWindows, a single close could consume an additional ~70 MB of memory. Also, in some situations the Page.numericId was zero in Page.writeObject, causing a ClassCastException when the Page field references were deserialized. Since the numericId was zero, the wrong Page (the initial Page) got deserialized. As far as I have been able to understand what's happening, the problems arise because of the cycles between components and the fact that the Pages are deserialized using different ObjectInputStreams. I'm not sure how the numericId could become zero. Removing the references to the content Pages from the ModalWindow sub-classes and using simple Models instead seems to have solved both problems. Questions: What is happening in the serialization/deserialization when this behavior arises? How can the numericId become zero in Page.writeObject (and sub-sequentially in Page.readObject)? Is it generally problematic to have field references to Pages in Components (or objects)? What would the most decoupled approach (object graph wise), thus minimizing serialization, be to implementing this?

Re: TabbedPanel and model load...
I suggest using the GoF memento pattern here. You keep your changes
in one or more mementos, which can be kept in the session. Then you
push the changes back to the domain model when you are happy with
them. We use this approach for modifying hotel reservations --
particularly because we need to see the price before the change as
well as with the change to generate e-mails, faxes, etc.

StringResourceModel - how to pass method call instead of bean
I actually have a follow up question regarding StringResourceModel - the
tutorial shows this example, which makes sense:
add(new Label(greetings, new StringResourceModel(label.greetings,
this, new Model(user;
Now, if I want to call a method that returns a String instead, like
so...
add(new Label(greetings, new StringResourceModel(label.allAlbums,
this, new Model(getTotalAlbums(;
^^^
...with my properties file having this entry:
label.getTotalAlbums = All Albums: ${someReference}
Obviously, this doesn't work, since the new Model(xxx) call expects a
bean to be passed in. How can I do this with a simple method call? And
what would my someReference var be?
Hope this makes sense - I just want to avoid passing in/creating a bean.

Re: Block second click
Ah, thanks for clearing that up.
In my case the processing has to be done once and only once, so
setEnabled(true) need not be called. After successful processing
setResponsePage(..) is called. So this should still work just for me,
right? I'll try tomorrow. If that doesn't work, I'll look at JS solutions.
Thanks for all the help,

this code doesn't work at all.
the onclick method isn't called at the same time by 2 request (2 link

They are synchronized by wicket itself.
So what happens with the code below is that the first request sets the
enabled to false
then does the processing, then wicket blocks the second request in the mean
time
then the processing is finished, the link is enabled again. That request
does its processing rendering
after it is finished wicket will release the second request and that does
exactly the same thing as the first.
So the heavy stuff is always done twice, but it is done twice in sequence
If you don't want that then the only solution is to block the second click
in the browser using javascript magic.

Components are stateful, so maybe you could just keep the

@Override onClick() {

try {
setEnabled(false);
doSomeHeavyWeightProcessing();

This creates a little race condition but if you can produce

I'm not attaching the whole listing of VRCDatePage, but the key
points are:
form.add(new AjaxSubmitButton(okButton, form)
{
protected void onSubmit (final AjaxRequestTarget
target, final Form form)
{
updateDate();
modalWindow.close(target);
}
});
where updateDate() updates the date model. Indeed the model gets
correctly updated since I see the new value gets to the database. But
the label doesn't get updated. I supposes everything was with the
setOutputMarkupId() and eventually with the
setOutputMarkupPlaceholderTag(), but clearly I'm missing something else.

n^2 loop in MarkupContainer?
Hi all, I'm using DataView in wicket 1.3 and we have ~400 items that are returned by a data provider. I'd expect the adding of the items to be rather quick but it turns out that it's not and it looks like the culprit might be MarkupContainer.put. That method expands the children array 1 entry at a time which makes the loop of adding the items n^2. Is there a good reason for this loop to be n^2 (memory conservation perhaps)? Is there any easy way around it? Thanks, Meetesh

Load resource from anywhere on the HDD
Hello, I have a little question: my app lets the user upload some files on the server side. I would like to put them somewhere on the server hdd, out of the context of the application (let say on /dev/etc/uploads), so when I redeploy my war (update of the system), all the uploaded files aren't going to be deleted. I just don't know how to reference them, when they are not in any package (this files are images, swf, and other binary, and I need to display images swf in html). I searched for some ResourceReference, but none of them lookup out of the webapp. Need I to write my own ResourceLocator/ResourceReference to achieve that? Or is there something existant in wicket? Thank you vm ;) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Block second click
this code doesn't work at all.
the onclick method isn't called at the same time by 2 request (2 link
clicks)
They are synchronized by wicket itself.
So what happens with the code below is that the first request sets the
enabled to false
then does the processing, then wicket blocks the second request in the mean
time
then the processing is finished, the link is enabled again. That request
does its processing rendering
after it is finished wicket will release the second request and that does
exactly the same thing as the first.
So the heavy stuff is always done twice, but it is done twice in sequence
If you don't want that then the only solution is to block the second click
in the browser using javascript magic.

Components are stateful, so maybe you could just keep the
state in your Link?
@Override onClick() {
if (!isEnabled()) {
return; // this shouldnt happen though?
}
try {
setEnabled(false);
doSomeHeavyWeightProcessing();
} finally {
setEnabled(true);
}
}
This creates a little race condition but if you can produce
it you could try using a real lock mechanism.

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

private JButton btnStart = new JButton(Start);
private JButton btnStop = new JButton(Stop);
private Thread clock = null;
public GuiThreadRunnable() {
initGui();
}
public void initGui() {
setTitle(Runnable);
setDefaultCloseOperation(EXIT_ON_CLOSE);
setBounds(200, 200, 400, 400);
getContentPane().add(lblTime, North);
JPanel p = new JPanel();
btnStart.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (clock == null) {
clock = new Thread (new Clock());
clock.start();
System.out.println( clock.start() );
}
}
});
btnStop.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
if (clock != null clock.isAlive()) {
clock.interrupt();
clock = null;
System.out.println( clock end );
}
}
});
p.add(btnStart);
p.add(btnStop);
getContentPane().add(p, Center);
setVisible(true);
}
public static void main(String[] args) {
GuiThreadRunnable guiThread = new GuiThreadRunnable();
}
class Clock implements Runnable{
public Clock() {
super();
}
public void run() {
try {
while (true) {
lblTime.setText( + new Date());
System.out.println( run() );
Thread.sleep(1000);
}
} catch (Exception e) {
}
}
}
}
Fine, it worked.
Btw, can give me more guide how to implement for your solution given ?

Just make a normal threadpool wilt a normal runnable that gets your

so the page can use that to construct itself after that runnable is done

informed you about it
generate all the back end data in a thread
and then construct the report page in a normal request (poll with an ajax

There are numerous topics about this in on the wicket list please search.

On Feb 12, 2008 7:36 AM, Henrik Lundahl [EMAIL PROTECTED] wrote: Hi, In my current project we have a page with six AjaxLinks that open different ModalWindows. We had implemented sub-classes of ModalWindow which had field references to the content Pages (the source of the iframes in the ModalWindows) created by ModalWindow.PageCreators. The references were there to extract state from the Pages when the ModalWindows were closed. The Pages also had field references to the ModalWindows in order to call close on them. Using this design, the serialization/deserialization increased seemingly exponentially for every opened and closed ModalWindow, causing a gigantic memory leak. After opening and closing a number of ModalWindows, a single close could consume an additional ~70 MB of memory. Also, in some situations the Page.numericId was zero in Page.writeObject, causing a ClassCastException when the Page field references were deserialized. Since the numericId was zero, the wrong Page (the initial Page) got deserialized. As far as I have been able to understand what's happening, the problems arise because of the cycles between components and the fact that the Pages are deserialized using different ObjectInputStreams. I'm not sure how the numericId could become zero. Removing the references to the content Pages from the ModalWindow sub-classes and using simple Models instead seems to have solved both problems. Questions: What is happening in the serialization/deserialization when this behavior arises? How can the numericId become zero in Page.writeObject (and sub-sequentially in Page.readObject)? Is it generally problematic to have field references to Pages in Components (or objects)? What would the most decoupled approach (object graph wise), thus minimizing serialization, be to implementing this?

Re: TabbedPanel and model load...
ok. never used memento, so I picked the book and read about it. I'm not sure
how to implement this. When do I retrieve a memento from the order? And in
the meantime, while adding and removing lines, is the Order updated and
saved in the DB? If someone reads the database, will he see the intermediate
changes?
Or do I for each add/remove/change the user makes:
- load the original order,
- apply any memento's present in a temp space (session)
- apply new changes
- create a memento
- discard changes to DB
2008/2/11, Scott Swank [EMAIL PROTECTED]:
The order has one or more order mementos (pre/post editing) and each
order memento has a collection of orderline mementos. The mementos
are completely opaque, and only the Order OrderLine are able to
inspect them and extract their content -- perhaps by implementing them
a static inner classes with private mutators.

easier to create a bean imho.

Re: adding context on redirect - Wicket 1.3 on Tomcat behind Apache httpd
Hello again, I'm still really struggling to find why the extra context is being added to the path. Could anyone help? Does anyone have a Wicket 1.3.1 setup on Tomcat behind Apache2? Is there a recommended setup e.g. Jetty? Working my way through the debug for Wicket, it looks like the page requests for PageLinks and setRedirects are the same. DEBUG - Page - ending request for page [Page class = abcd.app.page.LoginPage, id = 7, version = 0], request [method = POST, protocol = HTTP/1.0, requestURL = http://www.abcd.com/abcd/app/, contentType = application/x-www-form-urlencoded, contentLength = 54, contextPath = /abcd, pathInfo = null, requestURI = /abcd/app/, servletPath = /app/, pathTranslated = null] DEBUG - Page - ending request for page [Page class = abcd.app.page.NewThingPage, id = 6, version = 0], request [method = POST, protocol = HTTP/1.0, requestURL = http://www.abcd.com/abcd/app/, contentType = application/x-www-form-urlencoded, contentLength = 54, contextPath = /abcd, pathInfo = null, requestURI = /abcd/app/, servletPath = /app/, pathTranslated = null] Please, any help would be appreciated.

Thanks, Tim Hi All, I have a Wicket 1.3 app running on Tomcat 6 behind an Apache httpd server. Most of the app works great but any redirects using Component#setResponsePage adds the original web context to the path e.g. www.abcd.com/app turns to www.abcd.com/abcd/app and Tomcat complains /abcd/abcd/app is not available.

different behaviour explorer/firefox windowclosedcallback
Hi all,
I'm using version 1.3.1
I have a ModalWindow and in its method setWindowClosedCallback I pass a
WindowClosedCallback and then in its method onClose
I replace a panel with another called newPanel and finally I call
target.addComponent(newPanel)
The code follows
box.setWindowClosedCallback(new WindowClosedCallback() {
@Overridepublic void
onClose(AjaxRequestTarget target) {if (ok){
try {
man.delete(dev); //this call changes the panel
GroupPanel newPanel = new GroupPanel();
GroupPanel.this.replaceWith(newPanel);
target.addComponent(newPanel);
} catch (Exception e) {
error(e.getMessage());}
}}});
In firefox the code works perfectly, but it does not in explorer, because the
panel is not updated
Has anyone ever found this same problem?
Thanks
Rik

ModalWindow with Page memory leak
Hi, In my current project we have a page with six AjaxLinks that open different ModalWindows. We had implemented sub-classes of ModalWindow which had field references to the content Pages (the source of the iframes in the ModalWindows) created by ModalWindow.PageCreators. The references were there to extract state from the Pages when the ModalWindows were closed. The Pages also had field references to the ModalWindows in order to call close on them. Using this design, the serialization/deserialization increased seemingly exponentially for every opened and closed ModalWindow, causing a gigantic memory leak. After opening and closing a number of ModalWindows, a single close could consume an additional ~70 MB of memory. Also, in some situations the Page.numericId was zero in Page.writeObject, causing a ClassCastException when the Page field references were deserialized. Since the numericId was zero, the wrong Page (the initial Page) got deserialized. As far as I have been able to understand what's happening, the problems arise because of the cycles between components and the fact that the Pages are deserialized using different ObjectInputStreams. I'm not sure how the numericId could become zero. Removing the references to the content Pages from the ModalWindow sub-classes and using simple Models instead seems to have solved both problems. Questions: What is happening in the serialization/deserialization when this behavior arises? How can the numericId become zero in Page.writeObject (and sub-sequentially in Page.readObject)? Is it generally problematic to have field references to Pages in Components (or objects)? What would the most decoupled approach (object graph wise), thus minimizing serialization, be to implementing this?
