Hi All,

But if i move the  to the enclosing page and specify the

Any reason why Panels cannot act as the Markup provider for fragments?

The fragment is accessed only from within the Panel and hence I wanted to
keep it there instead of moving it to the enclosing Page.

Re: [Wicket-user] ajax causes page to expire when 2 browser tabsare open with bookmarkable pages

[Eelco Hillenius]

There's a trick in Wicket that tries to match the window name and the
page map name. This works in many cases. You'll find the script in
class WebPage, and if you use links with popup specs and a proper page
map etc, or e.g. open a new tab and paste your current URL in, you'll
find it works in many cases.

ListView look is more generic so I still feel DataTable is nice for my
case, and that work great. Only I need to add the label to the link
instead of panel

add(new BookmarkablePageLink("href", pageClass, new
PageParameters(parameters)).add(new Label("label", label)));

How do I recognize that an instance of that page is currently active

Should I explore all page maps?

We need a default that works for most users and via options something
that works for all. If we have something that by default works for

No we as a framework should think about ALL users not MOST users.
And we have quit a lot OSGI users as far as i know. And we should work
in that environment as good as we can.
So we need to check jars. And besides that we don't know it everytime that
it is a jar..
It is just and url..

We need to address the needs  of *most* users.  And for most users
it doesn't make any sense to reload templates from JAR files.

No, because when you're developing, you turn on the development
version, e.g. by providing a system arg when starting up or putting in
that web-xml parameter.

They should be used for development only. If you want to run your site
in development mode, that's fine, but let's just not make it a
default.

The quickstart thing: that's fine, I don't care what you do with that.
I'm talking about the fact that Wicket itself by default runs in
development mode, which is just a bad idea (like I've argued before).

Well, now people have problems when they actually deploy! I rather
have them look a bit harder when they develop.

Yes. If nothing is set explicitly, Wicket defaults to deployment mode.
And I don't care about what is done with the quickstart project. That
is probably used for just some testing and learning, so defaulting to
development sounds fine to me.

Hi,

I have a "best practice" question: I have a page with several panels,
each of them having a few Labels. This page shows a summary of the
customer infos. Each panel has a "Change" link that opens a page to
change the data. Since the panels can be embedded in different pages, I
want to go back to the page I came from after submitting the page on
which I can change the data.
For example: I'm on the summary page, see a typo in the address, click
the "change" link within the address panel. A page that allows me to
change the address opens, I change the address, click "Save" and want to
end up on the summary page on which I clicked "Change" again. Of course
the contents of the address panel should show the updated address then.

What's the best way to do this?

Thank you!

Re: [Wicket-user] DropDownChoice question

[Igor Vaynberg]

ive ran into this a couple of times myself.

there are two options

pass in a list of ids as the model and have ichoicerenderer resolve the id
to the text string

or work with pojos and have the model perform the conversion from object to
id and from id to object

Hi everyone,
I'm new to wicket and have a simple question:

I want to display a dropdown choice but I don't want to bind the entire
list of objects in it. Is there a simple way to bind a key-value pair
and get into a property the selected Id and not the selected object
(like .Net dropdown)?

The solution that I'm using is implement an object called Option that
it's basically a key - value pair.

//properties
Option selectedUser

//DropDownChoice binding
List users = new ArrayList()
for(User user in UserDao.getUsers())
users.add(new Option(user.getId(), user.getName()));

DropDownChoice choice=new DropDownChoice("ddc", new PropertyModel(this,
"selectedUser"), users);

Is there a simpler way to do this? maybe I don't understand the whole
idea of wicket very well, but I really don't want to put big objects in
the model to display only a key - value pair.

Thanks in advance

We actually already do that. Maybe we could do it more obviously,

Re: [Wicket-user] Too many open files

[Flemming Boller]

I like this idea too.

Perhaps Wicket should also output in the logs something like..  developement
mode active, remember to switch to production mode when going live...

That way I think you guys have covered every chance to help users of wicket.

I'm also in favor of turning this off by default, but in a slightly
different way: I'd like Wicket to operate in production mode unless
explicitly configured to operate in development mode.

No, because when you're developing, you turn on the development
version, e.g. by providing a system arg when starting up or putting in
that web-xml parameter.

They should be used for development only. If you want to run your site
in development mode, that's fine, but let's just not make it a
default.

The quickstart thing: that's fine, I don't care what you do with that.
I'm talking about the fact that Wicket itself by default runs in
development mode, which is just a bad idea (like I've argued before).

Well, now people have problems when they actually deploy! I rather
have them look a bit harder when they develop.

Yes. If nothing is set explicitly, Wicket defaults to deployment mode.
And I don't care about what is done with the quickstart project. That
is probably used for just some testing and learning, so defaulting to
development sounds fine to me.

Because then you have to restart everytime you have altered a HTML,
css, js, or properties file. Another thing is that you loose any
debugging tools you have installed. Deployment is only needed when you
package into a war. The quickstart is mainly used for development, and
therefore it is very reasonable to make the default development, until
you package your application.

Making this seamless in the building procedure is something that we
can do, but hampering development just because of plain stupidity is
not something I would like to enforce. If you enforce deployment as a
default people will go around it, ask questions on the list and look
at other frameworks because we don't have an easy development mode.

So the proposal is: set development mode in the web.xml for
quickstart. If *no* mode is set, then the default will be deployment.
When the application is packaged for war, using maven (or ant?) then
we will filter the property and make it deployment.

This way we cover the basics: development from the IDE is still
development, and building the package (WAR) will choose deployment as
a default.

When your application is set to production mode wicket tags will get
stripped leaving just plain html.

[Wicket-user] WebResource URL?

[Jonathan Sharp]

I have a WebResource which generates a stylesheet (css). How can I get a url
for this resource to pass in to the HeaderContributor.forCss() ?

Cheers,

Re: [Wicket-user] Wicket Stuff / Wiki

[James McLaughlin]

I would suggest sticking with moin until we know for sure it can't give us
what we need. Also, I'm not sure we need to force the entire website on to
the wiki. Let's leave that to the individual maintainers.

I've added a rewrite rule to hide the /cgi-bin/moin.cgi under /wiki-stuff,
per Upayavira's suggestion. Let me know if you see any problems.

thx,
jim

Re: [Wicket-user] Wicket-Stuff: ProjectMantainers page updated

[James McLaughlin]

Sounds like a good idea. For now, let's put a link on the front page to each
projects wiki. I am going to make an effort this week to theme the wiki
similar to the current wicket-stuff. I am hoping to put a left panel in that
provides navigation to each projects wiki. I'll get a backup/restore going
too. For orphaned projects, I think we should send another mail to the list
regarding projects w/o maintainers. Once we have determined projects are
orphaned but still viable, let's ask for volunteers to take them over.

Hi James (sorry for the late answer.. I was abroad & not connected to
the internet) I agree with you: there are a lot of data to collect
and, overall, a lot of things to do.
I'm in favour of creating a single page for each project with all the
details we need *and* a todolist for each project. Each of this page
eventually might become the "official" page of the project, if we
decide to use the wiki as website.

I see also that there are a lot of projects whose mantainer is
unknown... I think we should clearly decide what to do with them,
because abandoned projects will rapidly become unusable with 1.3 and
2.0

No, no-one actually needs reloading from the jar. Reloading as it
works for most people is done via another connection. And we can test
on what kind of connection it is.

But why not make deployment the default. Really, that makes so much
more sense to me.

All users really need this when developing. We already have two modes
for operation: development and deployment. It is not that hard to
comprehend is it?

If you have to explicitly set it, what prevents you from deploying it
to production anyway?

We could add to the quickstart project's pom a filter that alters the
mode from development to deployment when a war is built.

Re: [Wicket-user] ajax causes page to expire when 2 browser tabs are open with bookmarkable pages

[Eelco Hillenius]

You should make sure those two tabs each have their own pagemap.
Wicket tries as much as it can to do this automatically, but it helps
if you do this manually as well.

I'm also in favor of turning this off by default, but in a slightly
different way: I'd like Wicket to operate in production mode unless
explicitly configured to operate in development mode.

Re: [Wicket-user] Databinder 1.0

[Mats Norén]

Ah, ok, so by configuring a LSFB in Spring I could use databinder 1.1
in conjunction with all my other spring configured services?

"This factory bean will by default expose a transaction-aware
SessionFactory proxy, letting data access code work with the plain
Hibernate SessionFactory and its getCurrentSession() method, while
still being able to participate in current Spring-managed
transactions: with any transaction management strategy, either local
or JTA / EJB CMT, and any transaction synchronization mechanism,
either Spring or JTA. Furthermore, getCurrentSession() will also
seamlessly work with a request-scoped Session managed by
OpenSessionInViewFilter/Interceptor"

Thanks for the pointer!

This issue is a real show stopper.  Several users have reported to
me with painful setting into production of Wicket apps.

IMO we should  disable the shaky code that  reloads templates from
JARs (shaky  not because of Wicket,  but because of the  JVM), and
provide a setting to *optionally* re-activate it for the few users
that really need this.

The old dev list is shut down. You should have received a message
stating this. Now that we're incubating Wicket, we moved the dev list
over to wicket-dev at incubator.apache.org (send an email to
wicket-dev-subscribe at incubator.apache.org to subscribe). The user
list will follow in due time.

How customize your cell table :
You may create a panel which contains only your link :




and in the populateItem:
MyPanel panel = new MyPanel(componentId);
cellItem.add(panel);

And in your panel constructor
MyPanel()
{
add(new BookmarkablePageLink(componentId, Edit.class, new 
PageParameters(map)));
add(new Label("mytext", "click here"));
}

If you wich to add several types of content in your cell (a link, an 
image, a blob, a form, ...), or if you wich to select a row and make 
actions, it may more interresting to use a ListView.

Hi all,

This problem has cropped up a couple of times on this list.

Do you think we should add it to the Gotchas section of the wiki?

[Wicket-user] Ending up on the page that holds the Panel with the link I just clicked on (how about that for a catchy subject?)

[Johannes Fahrenkrug]

Hi,

I have a "best practice" question: I have a page with several panels, 
each of them having a few Labels. This page shows a summary of the 
customer infos. Each panel has a "Change" link that opens a page to 
change the data. Since the panels can be embedded in different pages, I 
want to go back to the page I came from after submitting the page on 
which I can change the data.
For example: I'm on the summary page, see a typo in the address, click 
the "change" link within the address panel. A page that allows me to 
change the address opens, I change the address, click "Save" and want to 
end up on the summary page on which I clicked "Change" again. Of course 
the contents of the address panel should show the updated address then.

What's the best way to do this?

Thank you!

- Johannes

Re: [Wicket-user] Databinder 1.0

[Nathan Hamblen]

Databinder 1.1 will use sessionFactory.getCurrentSession() within all
models. The default behavior will be a ManagedSessionContext bound
inside DataRequestCycle, but you can turn that off if you want to use
JTA or Spring-managed transactions:

[Wicket-user] DropDownChoice question

[Beto Siless]

Hi everyone,
I'm new to wicket and have a simple question:

I want to display a dropdown choice but I don't want to bind the entire
list of objects in it. Is there a simple way to bind a key-value pair
and get into a property the selected Id and not the selected object
(like .Net dropdown)?

The solution that I'm using is implement an object called Option that
it's basically a key - value pair.

//properties
Option selectedUser

//DropDownChoice binding
List users = new ArrayList()
for(User user in UserDao.getUsers())
users.add(new Option(user.getId(), user.getName()));

DropDownChoice choice=new DropDownChoice("ddc", new PropertyModel(this,
"selectedUser"), users);

Is there a simpler way to do this? maybe I don't understand the whole
idea of wicket very well, but I really don't want to put big objects in
the model to display only a key - value pair.

Thanks in advance
Beto

[Wicket-user] wicked wicket words :)

[Francisco Treacy]

Hi, I just wanted to know if it's indeed possible (and how) to change wicket 
control generated words such as
:wicket:interface: , and all other *wicket* stuff all over the place (I've 
already stripped out wicket html tags and attributes).

Eg. to put :application:stuff: instead. Because I shall not want to expose to 
the end-user I'm using Wicket. Although I'm aware it's a good propaganda 
strategy :)
I know it was discussed a couple of days ago, but I didn't get precisely how to 
change it. What should I override?

Thanks again,
Cheers,
Francisco

Just get another issue about having custom cell at DataTable.

If I just like to format the output, it is can be done using custom
AbstractColumn like

private static class WhenClosedColumn extends AbstractColumn {
public WhenClosedColumn() {
super(new Model("WhenClosed"), "WhenClosed");
}
public void populateItem(Item cellItem, String componentId,
IModel model) {
final Order order = (Order) model.getObject(cellItem);
cellItem.add(new Label(componentId,
Formatter.format(order.getWhenClosed(;
}
}

However, if I like to display a link, I will not work if I just add a
BookmarkableLink like


private static class OrderIdColumn extends AbstractColumn {
public OrderIdColumn() {
super(new Model("OrderId"), "OrderId");
}

private static final long serialVersionUID = 1L;

public void populateItem(Item cellItem, String componentId,
IModel model) {
final Order order = (Order) model.getObject(cellItem);
final Map map = new HashMap();
map.put("orderid", order.getOrderId().toString());
cellItem.add(new BookmarkablePageLink(componentId,
Edit.class, new PageParameters(map)));
}
}

It just display a text call "[cell]". How can I solve this?

[Wicket-user] Too many files open (not related to the other one, my guess)

[Nino Wael]

So we have a problem here where something that maybe tomcat or wicket are 
opening too many handles.

 

The issue are triggered by:

*   An exception from wicket
*   Message from wicket that the page has expired
*   Usage of a specific component that uses AJAX (might be a exception in 
there somewhere)

 

Our application has around 950 open handles on startup and that goes a bit up 
when visiting misc pages. But when any of the above happens handles are 
increased until the server dies.

 

>From what I can see now I can replicate some of the problem on my local 
>machine which are windows xp, server are win 2003. On local machine handles 
>goes up but at some point are cut down(and goes up again), this does not 
>happen on server it just continues to rise until death occurs:-(

 

Does anybody have something that can help?

 

Regards Nino

Re: [Wicket-user] [Wicket-develop] [ wicket-Patches-1562130 ] File descriptor leak in URLResourceStream

[Johan Compagner]

So instead of opening a connection inside the jar we just open a connection
to the jar only.
That would work for the app servers that uses the jar url connection but it
won't help
for example WebLogic and others. Because they use there own kind of thing..

[I sent this mail to wicket-develop as well, but I have not seen it
there yet, is that list filtered?]. This is a workaround method for the
wicket developers to solve the problem with "Too many open files" that a
lot of people have been having. It's a bug in Sun's JarURLConnection (I
reported it). The workaround should solve the problems even in
development mode.

Hi,

When you open an URL connection to an entry in a jar, you get a
JarURLConnection. The JarURLConnection in the package
sun.net.www.protocol.jar has an internal field

/* the url connection for the JAR file */
private URLConnection jarFileURLConnection;

which you cannot access in any way. When you ask for the last modified
time, the JarURLConnection will ask for the header field
"last-modified", which in turn will ask the jarFileURLConnection for the
that header field, which in turn will cause the initializeHeaders() call
in FileURLConnection, which in turn calls connect() and opens the file
(even though for the last modified header that is quite unnecessary).
The way to close the file is to call getInputStream().close() on the
jarFileURLConnection field, but unfortunately you can't since it is
hidden.

There is a very simple workaround though. In code:

URL url = new URL("jar:file:jarfile.jar!Entry.class");
URLConnection connection = url.openConnection();
if (connection instanceof JarURLConnection) {
JarURLConnection jarUrlConnection = (JarURLConnection)
connection;
URL jarFileUrl = jarUrlConnection.getJarFileURL();
URLConnection jarFileConnection =
jarFileUrl.openConnection();
long lastModified = jarFileConnection.getLastModified();
jarFileConnection.getInputStream().close();
System.out.println("last modified=" + new
Date(lastModified));
}

[note: you could probably do something like a while (connection
instanceof JarURLConnection) for jars in jars, but I haven't tested that
yet].

In other words, to get the last modified time of a jar file *entry*, we
just get the last modified time of the jar *file*.  (Note that in the
current Sun implementation that's what it does anyway). This makes sense
since you cannot change a part of the jar file without changing the jar
file itself. Now we do have the input stream to actual jar file, and we
can close it.

I'm sure there's an even better implementations that does not open the
jar file in the first place, but this should be fine for most purposes
and at least it kills the file descriptor leak.

Regards,
Sebastiaan

"last-modified", which in turn will ask the jarFileURLConnection for the
that header field, which in turn will cause the initializeHeaders() call
in FileURLConnection, which in turn calls connect() and opens the file
(even though for the last modified header that is quite unnecessary).
The way to close the file is to call getInputStream().close() on the
jarFileURLConnection field, but unfortunately you can't since it is hidden.

There is a very simple workaround though. In code:

URL url = new URL("jar:file:jarfile.jar!Entry.class");
URLConnection connection = url.openConnection();
if (connection instanceof JarURLConnection) {
JarURLConnection jarUrlConnection = (JarURLConnection)
connection;
URL jarFileUrl = jarUrlConnection.getJarFileURL();
URLConnection jarFileConnection =
jarFileUrl.openConnection();
long lastModified = jarFileConnection.getLastModified();
jarFileConnection.getInputStream().close();
System.out.println("last modified=" + new
Date(lastModified));
}

[note: you could probably do something like a while (connection 
instanceof JarURLConnection) for jars in jars, but I haven't tested that 
yet].

In other words, to get the last modified time of a jar file *entry*, we
just get the last modified time of the jar *file*.  (Note that in the
current Sun implementation that's what it does anyway). This makes sense
since you cannot change a part of the jar file without changing the jar
file itself. Now we do have the input stream to actual jar file, and we
can close it.

I'm sure there's an even better implementations that does not open the
jar file in the first place, but this should be fine for most purposes
and at least it kills the file descriptor leak.

[Wicket-user] ajax causes page to expire when 2 browser tabs are open with bookmarkable pages

[Nili Adoram]

Hi all,

I have a 'Item editing' page containing a form. When the form is 
submitted I want to return to the 'Item List' page but with fresh data.
In order to do that, after the form is submitted I look for the last 
instance of the Item List page in the page map, retrieve some of its 
page parameters (sorting, filtering, paging params) ,
and call setResponsePage with this page class and page parameters. This 
constructs a bookmarkable page with fresh data.
In addition this page contains an AjaxEventBehavior that refreshes some 
of the page components once a minute.
This all works great if only one browser tab is open.

However, if two browser tabs are open simultaneously things go wrong:
I open the Item List page in both tabs.
I open the Item page in one tab and submit the form.
I open the Item page in the second tab and submit the form.
When ajax tries to refresh the first tab it fails to find the page 
(inside DefaultRequestTargetResolverStrategyresolveRenderedPage()) and 
'page expired' page is displayed.

getCallBackScript of AjaxEventBehavior is called with false for  
recordPageVersion and false for onlyTargetActivePage.
If I modify onlyTargetActivePage to true one of the tabs stops 
refreshing after the aforementioned scenario.

Any ideas how to avoid this page expired problem ?

Thanks,
Nili

Re: [Wicket-user] Can I set the DropDownChoice to String[] or List instead of String?

Thanks, and just found out one cool feature of ListMultipleChoice is
that if the list I press into the constructor is not List, it
will persist the type.

However, if you use this API carelessly and think the List return from
the form is always List. Then you will get strangle null
pointer exception when you operate with the list instead of
ClassCastException as when I expect, as java will surpress the
ClassCastException sliencely and just return null to caller.

Not sure if the above information help anyone using this API
