Re: [Wicket-user] alternatives to set locale without using session?

2007-05-04 Thread ywtsang

Sorry that I am new to Wicket and may not know what the greatest values of
wicket are supposed to be.

We are evaluating different web frameworks right now and Wicket is one of
them.

One good and attracting point of Wicket to us is that it can separate
html/design and logic at a good way.
The usage of Wicket is simple and efficient.

But when looking more details of Wicket, we find that session is created for
every request.

This introduces another concern about the performance problem as our website
needs to serve a large volume of traffic.

As we find that it seems wicket 1.3 or 2.0+ are supporting no-session
pages, this fits our needs.

Since the handling of html/logic is attractive to us, we are trying to
seek possible solutions for session handling rather than just dumping out
wicket from our list just because of without session, can't get the most
benefit from wicket.

Or do you suggest we should look at wicket 1.3 or 2.0+ rather than wicket
1.2.6?

Wing

Our website will have different language. Customers can choose for
different
languages by clicking links like:

e.g.
/en/... (show english content)
/jp/... (show japanese content)
/kr/... (show korean content)
/zh/ (show chinese content)

Therefore I can deduce the language from the request link, it would be
nice if we can configure locale without the need of session creation.

Re: [Wicket-user] alternatives to set locale without using session?

2007-05-04 Thread Igor Vaynberg

1.3 is what i would look at, the current trunk in our svn. we just had a
1.3.0-beta release in apache incubator. 1.2.x doesnt have stateless support.

there are numerous threads on this list that try to disprove the session is
evil myth. so i would search the list for those first, before i made the
decision that my app needs to be stateless. wicket-1.3 also has a
second-level-session store which stores old pages to disk, further reducing
the session size. just my 2c.

Re: [Wicket-user] alternatives to set locale without using session?

2007-05-04 Thread Johan Compagner

in 1.3 you still can use getSession() and set the locale
But then you need to set it everytime because the session is created
everytime
if the pages are all stateless. So then you still can work with the normal
Wicket session object
Creating a wicket session object doesn't mean you create a http session
object. That only happens
if there are pages that need to go into the session.

Re: [Wicket-user] Good Tutorial on core wicket

2007-05-04 Thread Timo Rantalaiho

Also remember to have the wicket source code attached to
your IDE (easy with e.g. mvn -Declipse.downloadSources=true
eclipse:eclipse or idea:idea), and to have wicket-examples
project open in another IDE window. With this + working on a
real live project and with a little help from my friends and
these mailing lists, I've been getting on pretty well.
Anyway learning to use any framework is more about solving
real problems by coding on it than reading stuff.

I also subscribe to the user, dev and commits mailing lists
and try to read the messages at least cursorily. The most
problematic things (such as working with models :)) come up
a lot and often with realistic examples.

 Is it possible to ask understood community members to divide papers

 And therefore we might have some good data to compile into a nice

 With a good paper like that one, the goal would be to auto-answer questions

 Is it possible to use setMarkupStream to assign html to a web

 This is a question regarding inner workings, because the Answer is

 Wicket is Awsome, this should be written on some paper showing

 Creating a wicket session object doesn't mean you create a http session

Yes. When a client is not bound to a *HttpSession*, Wicket creates a
temporary *Wicket Session* object for every request. This is not kept
in memory, so when the request is done, the objects are free to be
garbage collected.

Does anyone know what is going on with this, or is there a pre-built jar

[Wicket-user] Updating textfield model in ajax onchange

2007-05-04 Thread Tauren Mills

I have a text field called 'dateField' on a form that has an
associated DatePicker control.  When someone selects a date in the
picker, I want to do an ajax call to refresh another component on the
page.  I need the dateField model to be updated in the ajax call.

I originally assumed the model would be updated automatically to the
new value, but it doesn't seem to be.  Now I'm thinking that is
because the form hasn't actually been submitted yet, which makes
sense.

So, how do I get the current value of the dateField inside an
onEvent() handler?  What is the best way to update the dateField's
model with the current value?  I've tried the following, but the model
value remains the same:

dateField.add(new AjaxEventBehavior(onchange) {
  protected void onEvent(AjaxRequestTarget target) {
// Refresh the ListView
 Logger log = Logger.getLogger(getClass());
 log.debug(Date Changed -- refreshing report);
 setSelectedDate((Date)(getComponent().getModelObject()));
 ListReportRow availList = createReportList();
 AvailabilityReportPanel arp = new
AvailabilityReportPanel(availReport, availList);
 ReportForm.this.availReport.replaceWith(arp);
 ReportForm.this.availReport = arp;
 target.addComponent(ReportForm.this.availReport);
   }
});

Note that setSelectedDate() is the setter for the dateField's model.
Also, createReportList() uses getSelectedDate() in an HQL query to
build the List.

What is the proper way to deal with this? Is there a way to indicate
that the form should submit during ajax calls?

Thanks!

this is a general html form thing. when you have a single textfield and you
press enter, the form is submitted. sometimes it happens even when you have
more then one textfield. to fix it you need to capture the enter keypress on
the field and return false so the event is discarded.

[Wicket-user] How may I access a Panel A from another Panel B (Ajax)?

2007-05-04 Thread Francisco Diaz Trepat - gmail


Hello, I have two panels, one that is mostly a form for login (user/pass
+button) and the other panel is just a link (onClick==logou).

Now I changed the button for the login form to an ajax button. Everythig
works fine.

The thing is that I had a code something like this in the logout panel.



@Override
public boolean isVisible(){
   return getMyWicketSession().isUserLoggedIn();
}

this code made every round trip evaluate whether the user was still logged
in and if so then render the appropriate option to logout.

how could I add to the target, the logout panel, do I need to pass it
through the constructor :


private final logoutPanel;
public LoginPanel(String id, LogoutPanel panel){
  logoutPanel = panel;

}

AjaxonSubmit(target...{
   target.add(logoutPanel)
}
??

Or could I just set in the constructor of the LogoutPanel
setOutputMarkupId(true) and then call on it from the onSubmit AJAX button?

I am a bit lost on this. Or could I just add a simple JavaScript 
document.getElementById('logoutPanel').style.visibility = visible;

Re: [Wicket-user] Using AJAX wicketSubmitFormById like a method call

2007-05-04 Thread James Renfro

Igor,
I had a feeling that was the situation. I'll take a closer look at my 
code with that in mind and if I can come up with a clear follow up 
question, I'll post some relevant excerpts.

Thanks very much for your help,
James.

Igor Vaynberg wrote:
 the short answer is: you cant do that. javascript is asynchronous, so 
 the request will start _and_ your function will continue running. 
 usually what is done is that you create a request object, and then 
 register success and failure handlers that are executed after the 
 request is done.

 you can do that using iajaxcalldecorator, or what you tried...calling 
 ajaxtarget.appendjavascript() should work as well.

 if you show us some more code/try to describe your actual usecase we 
 can probably help you more, right now its all very abstract.

 Hi,
 I'd like to do something slightly unusual and wrap the
 wicketSubmitFormById call in another javascript function -- I'm
 able to
 do this with no problem by overriding
 AjaxFormSubmitBehavor.onRenderHeadInitContribution and calling
 JavascriptUtils.writeJavascript on a wrapped getEventHandler. I
 can stop
 the normal attribute for 'onclick' or whatever from appearing
 inside the
 component tag by overriding onComponentTag. And by using text input
 boxes, I can pass 'arguments' to my method on the server inside using
 FormComponent.getConvertedInput. So far so good.

 The problem I have is that I'd like to actually 'return' a value back
 from the server in that Javascript function... so my function ends up
 looking just like a normal function call inside of my Javascript and
 returns the value that the server provides.

 I can see inside of wicket-ajax.js that there are three special tags:
 component, evaluate and header-contribution, each with their
 appropriate purpose -- I tried messing around with
 AjaxRequestTarget.prependJavascript so I could pass something through
 the 'evaluate' tag, but my javascript isn't sufficient to the
 task. Then
 I tried using AjaxRequestTarget.addComponent to modify another
 TextField
 and return the value through the DOM tree -- that works fine
 except for
 the fact that the order is wrong, so my method returns _before_ the
 component is updated.

 Then I noticed this interesting Wicket.Ajax.invokePostCallHandlers()
 call, which makes me wonder if there is already some nice clean
 mechanism in place for updating javascript variables thru wicket's
 java
 code.

 Apologies if this all makes no sense, but any advice or suggestions
 would be much appreciated. The basic requirement is just that I
 make a
 call in Javascript and get data back from the server as a 'returned'
 variable on the client.

 Thanks,
 James

Re: [Wicket-user] How may I access a Panel A from another Panel B (Ajax)?

2007-05-04 Thread James McLaughlin


Passing it in the constructor works, but you would have to call
setOutputMarkupPlaceHolderTag(true) on the logout panel otherwise it won't
be in the dom before the user logs in, and therefore can't be updated. This
is also why toggling the css attribute with script client side won't work
with isVisible false on the wicket side. If you do it by toggling an inline
stylesheet, then leave isVisble true on the wicket side. This doesn't really
mesh with the wicket way, however.

Since these two components operate together I would enclose them in a panel
together, something like

class SessionPanel extends Panel {

public SessionPanel(String id) {
 add(new LogoutPanel(logout));
 LoginPanel lp = new LoginPanel(lp);
 add(lp);
 lp.add(new AjaxSubmitButton(sb) {
 onSubmit(target) {
 target.addComponent(SessionPanel.this);
}
 });
}

}


best,

jim


That way you don't need to worry about what is in the client dom. But there
are a million other ways to do it :)

Re: [Wicket-user] How may I access a Panel A from another Panel B (Ajax)?

2007-05-04 Thread Gerolf Seitz


since you probably don't want to show the login form after a successful
login,
you could replace the login panel with the logout panel (and vice versa)
this could look something like the following:

// constructor of class LoginPanel
public LoginPanel(final String id) {
   super(id);
   this.setOutputMarkupId(true);
   Form form = new Form(form);
   form.add(new AjaxSubmitButton(login, form) {
   protected void onSubmit(AjaxRequestTarget target, Form form) {
   Panel panel = new LogoutPanel(id);
   panel.setOutputMarkupId(true);
   LoginPanel.this.replaceWith(panel);
   target.addComponent(panel);
   }
   }.setOutputMarkupId(true));
   add(form);
   }

any comment on this approach?

Re: [Wicket-user] Using AJAX wicketSubmitFormById like a method call

2007-05-04 Thread James Renfro

So although clearly AJAX is supposed to be mostly asynchronous. it looks 
like the underlying XMLHttpRequest object _can_ be synchronous.

If I modify wicket-ajax.js and set 'Wicket.Ajax.Request.async' to 
*false* -- suddenly my code works... i.e. I can code an 
AjaxFormSubmitBehavor.onSubmit so it takes a value from one 
FormComponent (the argument to the function), modifies it (in this case 
toUppercase), and sends it back to another FormComponent, whose node I 
can grab from the DOM tree and return inside my function.

So I guess my question is -- am I going to break something fundamental 
by doing this? It seem to work fine in my test case.

Javascript_function

script type=text/javascript id=onTestMethod1!--/*--![CDATA[/*!--*/
TestMethod1 = function () { 
var wcall=wicketSubmitFormById('form', 
'/portal/tool/52480496-d4f6-4278-0002-e65fdefcc0ef/?wicket:interface=wicket-247:0:form:-1:IUnversionedBehaviorListenerwicket:behaviorId=0wicket:ignoreIfNotActive=true',
 null, function() { }, function() { }); 
return document.getElementById('form_result').value;;};
/*--]]*//script

/Javascript_function

AjaxFormSubmitBehavior.onSubmit
@Override
protected void onSubmit(AjaxRequestTarget target) {

 The problem I have is that I'd like to actually 'return' a value back

 I can see inside of wicket-ajax.js that there are three special tags:
 component, evaluate and header-contribution, each with their
 appropriate purpose -- I tried messing around with
 AjaxRequestTarget.prependJavascript so I could pass something through
 the 'evaluate' tag, but my javascript isn't sufficient to the
 task. Then
 I tried using AjaxRequestTarget.addComponent to modify another

 and return the value through the DOM tree -- that works fine
 except for
 the fact that the order is wrong, so my method returns _before_ the
 component is updated.

 Then I noticed this interesting Wicket.Ajax.invokePostCallHandlers()
 call, which makes me wonder if there is already some nice clean
 mechanism in place for updating javascript variables thru wicket's
 java
 code.

 Apologies if this all makes no sense, but any advice or suggestions
 would be much appreciated. The basic requirement is just that I
 make a
 call in Javascript and get data back from the server as a 'returned'
 variable on the client.

2007-05-04 Thread Igor Vaynberg


if you change wicket-ajax.js in the way you showed below then all ajax
requests will become synchronous. while you wont break anything foundamental
you will make parallel ajax requests impossible. not a good thing imho. i
guess we need to add a parameter so that you can set the request to
synchronous just for that one call.

or do what i suggested and add a success handler that will execute the rest
of the function.

2007-05-04 Thread James Renfro

Good point. What I'm planning on is to inject my own ResourceReference 
version with the async set to false, but only for the one page where I 
need it to be synchronous. Since I'm overriding 
onRenderHeadInitContribution, I can just choose not to call super and 
the default .js files won't get included. But it would be much cleaner 
to be able to just set it programmatically, so I'd be very happy to see 
that parameter get worked into a future release.

Unfortunately, the spec I'm trying to implement (SCORM) requires that I 
expose a bunch of javascript methods with synchronous behavior, 
otherwise I would definite go the success handler route in this case.

Thanks very much,
James.

[Wicket-user] loading message for i18N from other sources

2007-05-04 Thread ywtsang


Wicket's i18n is nice and I can follow the example easily here:
http://cwiki.apache.org/WICKET/i18n-and-resource-bundles.html

Is it possible to have Wicket load i18n messages from sources like DB or
etc? As we want the messages to be dynamically updated for real time if
necessary.

I have looked into something like IResourceStream, but got no hint to go on. 

Thanks for your answer.

Re: [Wicket-user] How to remove a Behaviour?

2007-05-04 Thread Jonathan Locke



remove is a good addition, but what about isEnabled()?  that might be a nice
way to conditionally apply a behavior instead of removing it.

Re: [Wicket-user] Sessionless Wicket?

2007-05-04 Thread Jeremy Thomerson

Should I be concerned that the numbers in the following URLs jump so much?
This is on a page signed in as an admin, where I do have some callback links
that are stateful.

On one page view, here is an admin link:
http://www.texashuntfish.dev/thf/app?wicket:interface=:12492:list:posts:0:postSummary:delete::ILinkListener
I refresh (no other page views in between), and it changes to:
http://www.texashuntfish.dev/thf/app?wicket:interface=:13999:list:posts:0:postSummary:delete::ILinkListener

That's an increase of 1500 in a single page view... I am concerned that
somehow this means that I have 1500 components going into memory for a
single page? Is that number changing so drastically something to be alarmed
about?

Thank you!
Jeremy

Thanks to everyone for their help - I'm starting right away to convert

If you're only working with stateless pages, you don't detachable
models as those pages won't be stored to start with. But if you want
to reuse the models and components in stateful pages, it is better to
have that.

Eelco, I am curious about your statement when you have no callbacks,
you're
page will be stateless and not kept in memory... Most of my pages have
no
callbacks (by callback, I'm assuming that you mean a link that would
have
reference to wicket components in the URL, meaning that it is storing
the
state of that component so that it can further interact with it).

Yep. Normal Links, Forms, ajax requests etc.

I have
taken great care to control the URLs of the application, so almost every
page has only components that have standard URLs, with no references to
any
components, etc. The forms will obviously have a call back, and certain
links (particularly if you are signed in as an administrator - a lot of
links appear to edit and delete content that are all direct callbacks
with
obviously no direct URL encoding / decoding so that you can not use them
outside of your session).

Not sure what you're getting at...

So, how do I know if it's storing the pages in memory? Is there
something I
can do to tell it not to?

Yeah, you can give provide a HINT that they shouldn't be stored (that
they are stateless) by overriding getStatelessHint on the components
you put on the page. Note that if there is just one stateful component
on the page, that'll trigger the page to be marked as stateful UNLESS
you explicitly mark the page itself stateless (which is a bit cheaper
by the way, as it won't iterate over it's children to find out whether
it is stateless).

The method where this all happens is Page#isPageStateless.

Also, if you want to keep track of when user sessions are created,
create a custom session store by overriding newSessionStore on
Application and let your custom store extend HttpSessionStore or
SecondLevelCacheSessionStore and then override onBind which will be
called when (new) sessions are bound to the HttpSession.

that is actually the page id not component id. so either you create 1500
pages in between, or stateless pages generate random ids - which it didnt
look like from the code...
