I use an AjaxFormComponentSubmittingBehavior onblur for each field -
so it triggers the submission processing behaviour (including
validation) for the given field - although it updates the model. You
could use an applicable Ajax behaviour and then call the component's
validate() method if you wanted to avoid the model update.

Whats the best way to do a form component validation?

2009-04-23 Thread Jason Wang


Hi all,

I have a form with a couple form components, most of which have 
validators attached. For example, the mobile number input field has a 
patternValidator attached:


mobile.add(new PatternValidator("^[1-9]([0-9]{8,14})"));

I have hooked all the validation actions with "onblur" events using this:

AjaxFormValidatingBehavior.addToAllFormComponents(signUpForm, "onblur", 
Duration.ONE_SECOND);


But unfortunately all the validations are triggered as soon as the focus 
leaves any of the form component.


Is there a way to hook the validator(like the patterValidator) with the 
event(onblur for example) on the form component(the mobile filed) rather 
than the whole form?


It would be nice that the AjaxFormValidatingBehavior class could provide 
the option to trigger the validations on events on every components.


Thanks.

Jasonw

Here's the link to the quickstart:
http://www.nabble.com/file/p23208312/myproject.zip myproject.zip 

Some notes:
1) This won't work as written in Jetty. Jetty uses an unmodifiable map for
request parameters so to make it work in Jetty, one would need to change the
rewrite rule to set a request attribute instead of a request parameter.

2) I had to include the jar for the 3.2.0 version of the URL Rewrite filter
as it isn't in the central Maven repo yet. 

3) Instead of launching to the start page of the app I would recommend going
straight to "http://localhost:8080/whateveryouwant/testpage1";. Replace 
"whateveryouwant" with anything. That's the value that will be rewritten out
of the URL and set as a request parameter with the name "organization". 

4) I'm using the HybridUrlCodingStrategy for URLs. You should be able to use
any URL coding stratgy, but since this is what I'm using in my main app,
it's what I've configured the rule for.

How to handle multiple choices?

2009-04-23 Thread Major Péter


Hi all,

I'm quite new to Wicket, and I really started to liking it. ;)
But now I have a problem, which I don't know how to solve:
In my application there are groups, users, and memberships. Every 
membership has an entitlement (member, group leader, pr_manager and so 
on), which is used for authorization information at other pages.
I need to make a page where these entitlements can be easily managed by 
the group leader (for example: add an entitlement, remove an entitlement 
- a member can have multiple entitlements at the same time and an 
entitlement can be belong only to one member).

Is there some tool, which could make this to a little simpler problem?
(I was thought about ListView with RadioButtons, where the RB's are 
interpreted by columns, but I didn't found an example to do this)

Please help me.
Thanks in advance.

Best Regards,
Peter Major

RadioGroup and nested ListView

2009-04-23 Thread c c

Hi all, I am new at this so please be gentle.

I would like to use a RadioGroup to select one "element" among a list
of elements organized in groups.
I have two nested ListView, the outer looping over the groups, the
inner one looping over the elements of each group.
Each element of the inner listview has a Radio.

I have tried the following but I get the error:
WicketMessage: Component radio must be applied to a tag with 'type'
attribute matching 'radio', not 'null'
probably because the radio are in the items of the inner ListView
while the outer ListView is added to the RadioGroup.


Form form = new Form("form");
add(form);  
final RadioGroup radioGroup = new RadioGroup("radioGroup", new Model());

ListView listviewGroups = new ListView("listviewGroups", groups){

@Override
protected void populateItem(ListItem groupItem) {
SubCategory group = (SubCategory) groupItem.getModelObject();
groupItem.add(new Label("group", group.getName()));

ListView listviewElements = new ListView("listviewElements",
 service.getElementsForGroup(group.getId())) {

@Override
protected void populateItem(ListItem elementItem) {
Element element = (Element) 
futureItem.getModelObject();
elementItem.add(
new Label("element", 
element.getName()));
elementItem.add(
new Radio("radio", 
elementItem.getModel()); 
}   
};
groupItem.add(listviewElements);
}
};
radioGroup.add(listviewGroups);
form.add(radioGroup);

/*- and this in the html ---*/

















Many thanks in advance for any help!

Use a WebMarkupContainer and either:

Ajax timer behavior not updating component in IE, Chrome and Opera

Hello,

I am sorry I am not going to be very specific here, because the error
I am experiencing is not very deterministic.

The scenario: I am using 1.4-rc2, and I have a page with several (six,
to be precise) panels which load its contents by using a subclass of
AbstractAjaxTimerBehavior, which polls the server until the data for
each of them is ready and if so returns a Panel with the adequate
content. I cannot use LazyLoadPanel because I need their data
obtention to be concurrent, and LazyLoadPanel would serialize their
requests.

This page works perfectly in Firefox, but sometimes I get some weird
behaviour in other browsers. The one most affected is Chrome, but
Opera 9.6 also fails sometimes, and the same goes for IE7.

So, I have this piece of HTML in my page:

ITALY

...being "row248" a wicket-generated markup id, and of course a unique
identifier in the page.

I can see in the "Wicket AJAX Debug" window that the panel containing
the data is correctly retrieved...

INFO:
INFO: Initiating Ajax GET request on
?wicket:interface=:220:test2:content:rows:0:row::IActivePageBehaviorListener:0:-1&wicket:ignoreIfNotActive=true&random=0.6747844972740807
INFO: Invoking pre-call handler(s)...
INFO: Received ajax response (226 characters)
INFO:

INFO: Response parsed. Now invoking steps...
INFO: Response processed successfully.
INFO: Invoking post-call handler(s)...
INFO: Calling posponed function...
INFO: last focus id was not set
INFO:

...but *that is never updated in the page's DOM*, and I never get
to see it. The symptoms are exactly the same in the three mentioned
browsers, and it only happens "sometimes".

And I don't get any errors in the javascript console...

Any clues?

Thank you,
Daniel.

Re: Problem with ListView embedded in another ListView

is the link repainting the entire listview? in that case all values
will be lost because they are not submitted. either use
ajaxsubmitlink, or only repaint the new row. there is an article on
wicketinaction.com that shows how to do it.

Re: datatable columns shuffle

datatable does not support changing columns, something on a todo list
to fix in 1.5. for now you can just recreate the datatable itself.

Re: Exceptions after Tomcat restart

looks like tomcat is trying to save sessions to disk and restore them
on restart. this should be turned off while developing because you
change the structure of objects and they cannot always be loaded back.
this is a tomcat setting.

Problem with ListView embedded in another ListView

2009-04-23 Thread Thierry Leveque

Hi

I have a ListView that is embedded inside another ListView. Both ListView
are dynamic: Both have an Add and a Remove button.
The ietms in both ListView are a series of form fields.

The problem I have is only with my second ListView when I add more than one
item without submitting the form. The fields lost their content. i.e. If I
click on my Add button a new row with fields appear. I put some values in
those fields. I click again on my Add button, the new row appear but the
values I just enter before are lost!
And yes I put my getReuseItems() to true.

The same thing is working fine with the ListView at the first level. The
values in the fields are not lost.
The problem is only with the embeded one.

Any idea??

datatable columns shuffle

2009-04-23 Thread Alfredo Aleandri


Hi,
I'm a wicket beginner.
I'm trying to shuffle the columns of a datatable using an 
AjaxFallbackLink, this is my code (only relevant part):


my WebPage content:

   private AjaxFallbackDefaultDataTable usersTable;
   private List> userColumns = new ArrayList>();
   private UserProvider userProvider = new UserProvider();

   public QueryPage() {
  
   userColumns.add(new PropertyColumn(new Model("First 
Name"), "FIRSTNAME", "firstName"));
   userColumns.add(new PropertyColumn(new Model("Last 
Name"), "LASTNAME", "lastName"));
   usersTable = new AjaxFallbackDefaultDataTable("users_table", 
userColumns, userProvider, 20);

   usersTable.setOutputMarkupId(true);
   add(usersTable);
  
   add(new AjaxFallbackLink("users_shuffle") {

   @Override
   public void onClick(AjaxRequestTarget target) {
   Collections.shuffle(userColumns);
   usersTable = new 
AjaxFallbackDefaultDataTable("users_table", userColumns, userProvider, 20);

   if (target != null) {
   target.addComponent(usersTable);
   }
   }
   });

   }

my html page content:

   Shuffle!
   [table]


When I click the ajax link the "onClick" is executed, the userColumns 
list is shuffled but the page rendering is always the same as defined in 
the constructor of the WebPage.

I've tryied also using a standard Link (no ajax) getting the same result.
I'm using Wicket 1.4rc2.

Thank you

Alfredo

Wicket doesn't do anything with native stuff—we're doing pure Java.
Either you did something strange, or there's a bug in WebSphere or the

Two points:

1 - really long lists are nearly always bad for users

2 - can't you just do this with CSS?  put a div around the list and

Re: How to send data to server - form submission

2009-04-23 Thread Juan G. Arias

I don't see why having multiple ways to send information is reinventing the
wheel.
My point was that form submission is a standard for send information. Is the
classic way.
Ajax doesn't require this. You are able to send information on any
javascript event. And maybe someone had implemented that.

I agree is simpler to have only one entry point. And has consistency, seems
robust.
Wicket triggers the same "conceptual" event, form submission. No matter how
this is triggered, regular sumit or ajax.

Finally, I will add the form component and send info using the standard way.

Thanks!
Juan

Re: Registering 'global' Ajax listeners?

2009-04-23 Thread Peter Ertl


Maybe these help...

- you can override WebApplication.newAjaxRequestTarget(Page page)
- you can use AjaxRequestTarget.addListener() to add listeners

AW: Pagemap locking issue

2009-04-23 Thread Tokalak Ahmet

Thanks for your feedback Martijn. 
Yes, you're right. I will solve this issue using threads.

Von: Martijn Dashorst 
An: users@wicket.apache.org

Betreff: Re: Pagemap locking issue

Why would you want your users to wait for 1 minute to get results? On
what planet and time/space continuum do you expect users to wait for
that?

Don't do the computation in the request thread. Compute the stuff in a
separate thread, process or whatever and subscribe the user's
session/page/whatever to a future outcome of that thread, and then
rendering that directly.

Sounds more like an application design issue than anything related to wicket.

Normal rendering, but as I mentioned later in the thread, even though it was
Wicket issuing the redirect, it was somehow being caused by my attempts at
URL rewriting and the redirects do not occur if the URL manipulation is
disabled.

Re: QueryStringUrlCodingStrategy not encoding "te?t" - is this correct?

Unless I'm reading the RFC wrong,  the behaviour of
QueryStringUrlCodingStrategy is correct...

http://labs.apache.org/webarch/uri/rfc/rfc3986.html#components

The query component contains non-hierarchical data that, along with
data in the path component, serves to identify a resource within the
scope of the URI's scheme and naming authority (if any). The query
component is indicated by the first question mark ("?") character and
terminated by a number sign ("#") character or by the end of the URI.

   query   = *( pchar / "/" / "?" )

The characters slash ("/") and question mark ("?") may represent data
within the query component. Beware that some older, erroneous
implementations may not handle such data correctly when it is used as
the base URI for relative references (Section 5.1), apparently because
they fail to distinguish query data from path data when looking for
hierarchical separators. However, as query components are often used
to carry identifying information in the form of "key=value" pairs and
one frequently used value is a reference to another URI, it is
sometimes better for usability to avoid percent-encoding those
characters.

 In FF it doesn't happen.
 in IE6 it doesn't happen as well.

 I looked in the mailing list and couldn't see something about it.

 Was it fixed in 1.3.5 ?

Re: Exceptions after Tomcat restart

Our  Eclipse users have varying issues with Tomcat, and I've picked up
a couple myself today in Intellij cause by half-assed deployments,
although I suspect that's more a Maven issue. /tangent.

In Eclipse, for us, it seems to be caused by resources from a earlier

Re: How to set content of an ajax enabled link?

By content you mean the text yeah? Create your link (We use
AjaxFallbackLinks for Ajax links, but there's others), and then create
a label with an appropriate model, and add the label to the link.
You're markup would look like so:

How dynamic a content you're after really depends on what you're
doing. If you're not using a dynamic model (I'm a big fan of property
models over domain objects) you could easily change the Model of the
linkContent label in the ajaxLink's onUpdate method. Just make sure
you add the link to the ajaxRequestTarget to see it update.

If you want a more specific model behaviour, not too hard to knock up
a class implementing IModel that does what you need.

Liam Clarke

Native memory leak using wicket-1.2.6 / IBM JDK 1.4 / Windows 2003 Server SP1

2009-04-23 Thread Basak, Prasan (TCS)

Hi,

Our web application use following configuration for development, and it
frequently gives Java core dump without enough load.
We contacted IBM support, who, after analysing dump file, has found that
some of the html files of our app have been stored in the native memory
space ( not heap memory) , presumably by wicket.

Did any other user of wicket 1.2.x experience similar issues?

Env:
JDK = IBM JDK 1.4
OS = Windows 2003 Server SP1
Application Server = Websphere Process Server 6.0.2x
Web application = Is a pure java app
Wicket Version = 1.2.6

Thanks
prasun

 browsers are asynchronous, so you might have a race codition. eg
 browser requests the data url and you press the refresh button, so now
 there are two urls in the queue: the data and the page. if page is
 processed first then the data url will fail because when the page is
 first constructed you have a loading panel in there. makes sense?

 take a look at wicket's ajaxlazyloadingpanel, it might have a way to
 handle this.

How to set content of an ajax enabled link?

2009-04-23 Thread HHB

Hey,
Is there a way to set the content of a link 
dynamically (the value is coming from model object)?
The link has to be Ajax enabled for sure.
Thanks.

Exceptions after Tomcat restart

2009-04-23 Thread Wicket Newbie Wicket Newbie

Hi everybody,

our wicket application behaves in a strange way. After restarting Tomcat server 
in Eclipse everything works fine. But after restarting Tomcat server in Eclipse 
for the second time, Page Expired is shown. Several Exceptions appear in log 
file, but I don't know, how to get rid of them. After the next restart 
everything is fine again. The problem does not just appear in combination with 
Eclipse.


Hope, anybody can help.

Betty


These exceptions occur the most:

I don't think it's the same issue, but I had some trouble with loading
a Flash stream and IResourceListener

 Now I know what is happening more in detail. It is not easy to
 explain, sorry for the long text:

 I have:

  - DataPanel: a panel with data I want to show.

  - LoadingPanel: a panel which just shows a "loading..." image.

  - PanelLoader: a Panel with an inner panel called "content", which
 is loaded initially with LoadingPanel, and sets an AjaxTimerBehavior
 which polls the server until the data is ready, and then creates the
 DataPanel, replaces the inner "content" with this DataPanel, and stops
 the timer behavior.


 All this works perfectly until I use a subclass of DataPanel called
 FlashDataPanel which, for showing data, shows a flash object which in
 turn has to make a request from the browser to get its data. I offer
 this data to the flash object as a resource, by making this subclass
 of DataPanel implement IResourceListener, and implementing its
 "onResourceRequested" method. The URL I add to the flash object is
 obtained like:

        CharSequence dataPath =
 RequestCycle.get().urlFor(FlashDataContainer.this,
 IResourceListener.INTERFACE);
        return RequestUtils.toAbsolutePath( dataPath.toString() );

 The problems seems to be that *sometimes, and only sometimes* (maybe
 once each 50 correct loads or so), the "onResourceRequested" method
 gets called on the LoadingPanel instead of the DataPanel... which is
 something strange to my eyes (unless there is something I don't
 understand, of course). The URL is created passing the
 FlashDataContainer.this object, so I cannot understand how it gets
 called on a LoadingPanel, which of course does not implement
 IResourceListener, and thus provokes this exception.

 Regards,
 Daniel.

Re: Random exception at ResourceListenerInterface

By the way, in case this gives you more information, my "DataPanel" is
very similar to the "OpenFlashChart" Panel class defined in
http://cwiki.apache.org/WICKET/open-flash-chart-and-wicket.html, as in
fact my flash object is Open Flash Chart (I am loading many charts in
the same page in an asynchronous way).

Daniel.

QueryStringUrlCodingStrategy not encoding "te?t" - is this correct?

2009-04-23 Thread Antoine van Wel

Hi all,

using 1.3.5 :
mounted a bookmarkable page using the QueryStringUrlCodingStrategy, now I'm
passing in a page parameter with key "search" and value "te?t" -- the target
url is

?search=te?t

tracing this, turns out the QueryStringUrlCodingStrategy just applies UTF-8
encoding (or whatever has been set on the application level).

Are this behavior and the constructed URL correct? I would expect a URL like

?search=te%3Ft


regards
Antoine
