Strip header contributors from Ajax response.

[Apple Grew]

I have a component which contributes Js headers. This component is also
rendered by AjaxRequestTarget. The problem is that when rendering ajax
response the Js codes too are getting rendered. These Js codes were already
contributed when this component first rendered (in non-Ajax mode).

To fix this what I initially did was that in the onBeforeRender method of
the component I was checking if the response NOT isAjax then add the header
contributors, else, remove them. This was working fine, but problem is if I
want to implement this is other components I would have to copy n paste the
codes. So I decided to implement a behavior. I added all the header
contributors to that behavior and it was supposed to do the job of adding n
removing the header contributors. But we can't modify hierarchy from
beforeRender of behavior so I am now stuck. Furthermore, this approach is
not capable of removing JS contributed by super calsses of the componenet.

Please suggest.

Thanks and regards,

Re: Back-button friendly ajax wizard navigation

[Brian Laframboise]

Thanks Edward. I was hoping for some means of doing this in a
redirect-after-post kind of way so that the javascript response to the
client actually caused the browser to request the next wizard page via a new
url, creating a back-button history entry. I guess generating that URL for a
non-bookmarkable page during an ajax form submission and causing the client
to redirect is not doable.

In my particular case,  I have a wizard step with a single radio group and
no default option. Here I expect many users to simply click 'Next' and I was
hoping to save them the full page submission just to display the error
message. Unfortunately, here the "onblur" approach clearly won't work and I
can't think of another event handler onto which I could attach it.

However, it still sounds useful for my other form elements and I'll try it
out there.

Thanks again for the help.

Re: Which form componnent had focus when form was submitted?

[Igor Vaynberg]

you can create a subclass of hiddenfield that would add the necessary
javascript for you and you will end up with a nice reusable component.

Ajax call gives up

[Martin Grigorov]

Hi,

I'm facing a nasty problem in my app.

Submitting a form with Ajax (wicketSubmitFormById) makes the Ajax call
back to the backend and after that immediately closes the connection for
some unknown reason. The backend successfully process the request but at
the end fails with "Broken pipe".

Debugging wicket-ajax.js shows that xhr.readyState is 2 (not 4) and soon
after that it makes full page reload (window.location=...) which
completely breaks the single-page model for our application.

Google returns
http://www.mail-archive.com/wicket-u...@lists.sourceforge.net/msg25940.html 
that looks very much like my problem. Unfortunately I cannot find what was the 
solution provided by Matej.

Anyone else ever experienced something similar ?

CSS not loading on WebMarkupContainer refresh

[taygolf]

Hey guys. I have a page that contains 4 panels. In one of these panels I
have a listview that is inside a WebMarkupContainer.

The user click on an ajax link which opens up a modal. The user fills out
the form and clicks submit. On submit the new information is added to the
list view and the WebMarkupContainer is refreshed and the new information is
displayed in the panel

All of this is working just fine.

The problem that I am running into now is that I want to add a tooltip to
the data that is in the listview. I have done this by adding a
AttributeModifier to my code and then adding the css file to my html code.

FOr some reason this will not work unless I refresh the entire page. So when
the new data is added to the listview the css does not work. After I click
the page refresh button it works prefectly.

How can I get it to work when the WebMarkupContainer is refreshed?

Thanks

T

Re: String Resource Loading from DB

[Josh Glassman]

Not sure what you mean about implementing a unique class... any class which
inherits from Component can call getString(String key), which will call your
custom IStringResourceLoader.  Additionally, you can set the locale on any
MarkupContainer or the Session, and Components will use their parent's
locale falling back to the Session's.

You can also use the wicket:message tag directly in your markup, which uses
whatever locale it's associated class uses.

What we do is set the locale on the Session, and use that and a resource key
to pull the string from the database.  We use DB caching, and turn off the
built-in resource string caching that wicket does (see below, goes in
WebApplication.init()).

getResourceSettings().setLocalizer(new Localizer() {
   @Override
   protected void putIntoCache(String cacheKey, String string) {
  // Do nothing... no caching desired, since our DB layer caches
   }
});

Simple TextField Override and A SubmitLink Question

[Brian Mulholland]

I am a Wicket n00b.  Just learning and writing a demo app to evaluate
Wicket vs a few other MVC solutions which are having demos written by
other developers in the group.  I am having two issues.

Issue 1 involves me trying to write a custom TextField to demo the
idea of overriding a control and outputting custom HTML to support it.
 The plan was to override the onRender and write out plain text when
the control is disabled instead of writing out a textbox with the
enabled flag set to false (which is the default behavior).

So I wrote a TextField with the following onRender:

@Override
public void onRender(MarkupStream stream)
{
  if(this.isEnabled())
super.onRender(stream);
  else
  {
getResponse().write(getModelValue());
this.renderNext(stream);
  }
}

I read about the renderNext on nabble, which resolved one exception I
got, but now it throws exceptions saying that it cannot find the
component as if I declared it in html, but did not add it to the
hierarchy.  I know the code outside this render is fine because if I
change the code to keep the super.onRender() call, but merely surround
the super with a span tag with display:none, it works fine.

But I really wanted this style to work as a proof of concept of
overriding the onRender to output whatever HTML we need.  Customizing
components to put our custom HTML seems to be Wicket's greatest
feature.  But clearly there is some aspect of the onRender contract
that I am missing.  The super must be taking care of something that I
am not aware that I am required to take care of.  Any Ideas?

Issue 2: Same page.  When the page is in readOnly mode, I set a
readOnly flag, set all my controls to disabled, and change what links
show.  I am using SubmitLinks.  When the page loads the first time one
set of actions is enabled (such as a Modify link) and upon hitting
modify, I set the controls to enabled, and display Save and Cancel
links while hiding the others.  But upon getting to the modifiable
mode, none of the SubmitLinks work.  I even tried showing all the
links all the time and once I have run a request through the app, none
of the links respond anymore.

However, I found that if I eliminate the code that iterates through my
controls, the links work.  I wrote a simple setEnabled method that
uses the IVisitor interface like so:

@Override
public Object component(Component comp)
{
  MyBasePage page = (MyBasePage) comp.getPage();
  if(FormComponent.class.isAssignableFrom(comp.getClass()))
comp.setEnabled(!page.isReadOnly());
  return IVisitor.CONTINUE_TRAVERSAL;
}

Thus each page will inherit from MyBasePage and just change the
readOnly flag.  I don't want to disable every Component since I want
some of the links and other things to work.  I may have to make this
method smarter in the future, but for now this is pretty close to what
I want...except for the small detail of not actually working.  I know
that the links are never getting disabled by this code because I
debugged through it, and also echoed out the isVisible and isEnabled
after the fact.  However, when I don't do this, my links refuse to
respond on the 2nd request.  Further, the request they stop working on
is when I am ENABLING the controls.

So why if the links are not disabled, might they not be responding
when I click on them.  The onSubmit() method of the form never gets
control.  I've tried to provide all the information I know.  Anyone
have ideas?  Even if you don't know what might be wrong, if you can
suggest an avenue of investigation that would be helpful.

Also, what resources do you suggest for a Wicket noob?  I've been
looking at the javadoc and the Wicket wiki and the examples on the
apache site.  But they all seem fairly light.  The javadoc often has
insufficient detail (see the onRender issue), the wiki has large
important sections simply labelled "TODO", and the examples seem
mostly slanted toward things that don't really show off the good
stuff.  Are there other good resources that I should be using?

Re: Which form componnent had focus when form was submitted?

[Warren Bell]

Thats what I am currently doing. It just felt to much like something I
used to do in Struts. I don't know if there is much call for this, but
it would be nice to have an onSubmit for a text field or other form
components that would get fired off if that component was in focus when
the form was submited, or maybe a Form onSubmit(Component
componentInFocus). Just a thought, I end up doing a lot of this.

Re: OnChangeAjaxBehavior and other form components

[Steven Haines]

I finally got everything working... Here is what I did for anyone that comes 
across this problem..

I added an onComponentRendered() method to my AjaxFormSubmitBehavior in that 
method I added the new Wicket.ChangeHandler (I saw the code in the 
OnChangeAjaxBehavior class):

@Override
protected final void onComponentRendered()
{
Response response = getComponent().getResponse();

final String id = getComponent().getMarkupId();

response.write( JavascriptUtils.SCRIPT_OPEN_TAG );
response.write( "new Wicket.ChangeHandler('" + id + "');" );
response.write( JavascriptUtils.SCRIPT_CLOSE_TAG );
}

So here is my final zipcode field:

zipcodeField.add( new AjaxFormSubmitBehavior( form, "onchange" )
{
private static final long serialVersionUID = 1L;

@Override
protected void onSubmit( AjaxRequestTarget target )
{
 // Access your objects through the form bound in your 
CompoundPropertyModel
 myModel.getZipcode();
 myModel.getStreet1();
}

@Override
protected void onError( AjaxRequestTarget art )
{
// Called for things like validation errors ...
}

@Override
protected IAjaxCallDecorator getAjaxCallDecorator()
{
return new AjaxCallDecorator()
{
private static final long serialVersionUID = 1L;

@Override
public CharSequence decorateScript( CharSequence script )
{
// Only return the script (which means that it will be 
executed) after the
// user enters the 5th digit (or more)
return "if(this.value.length >= 5){" + script + "}";
}
};
}

  @Override
protected final void onComponentRendered()
{
// Creates a new Wicket.ChangeHandler for immediate 
notifications of
// change events
Response response = getComponent().getResponse();
final String id = getComponent().getMarkupId();
response.write( JavascriptUtils.SCRIPT_OPEN_TAG );
response.write( "new Wicket.ChangeHandler('" + id + "');" );
response.write( JavascriptUtils.SCRIPT_CLOSE_TAG );
}
} );

Re: Back-button friendly ajax wizard navigation

[Edward Zarecor]

Since you are changing the DOM dynamically using Ajax, the browser --
correctly I would say -- isn't considering this a page change, so the
back button should take you back to the page prior to the wizard.

The browser history will be immutable from JavaScript, so that's not an option.

To achieve the user experience you want, I think the best alternative
is to validate your fields via Ajax onblur, but move between wizard
steps using a form submit.

Hope this helps.

Ed.

Back-button friendly ajax wizard navigation

[Brian Laframboise]

I have a Page with a Wizard component. Currently using the next and previous
buttons perform full-page (non-ajax) form submissions which has the
necessary side-effect of being back-button friendly.

I implemented an ajax version of the Wizard in order to get faster
validations. That part works great - however, back button support is broken.
(Clicking the browser back button brings the user to the page before the
wizard page, instead of going back one page in the wizard).

Is there a way I can use Wicket's ajax form support to have these faster
validations while not breaking the back button? I tried doing:

protected void onSubmit(AjaxRequestTarget target, Form form) {
if( target != null ) {
...
setRedirect(true)
}
}

to redirect the response in order to create a browser history entry. It
didn't work, so clearly there's something fundamental here that I don't
understand.

Any suggestions? Thanks!

Re: Which form componnent had focus when form was submitted?

[Igor Vaynberg]

you have to keep a HiddenField component and populate its value using
javascript.

Which form componnent had focus when form was submitted?

[Warren Bell]

Is there a way to figure out in a forms onSubmit which text field or
button had focus when the form is submitted. I have done something in js
to achieve this, but wanted to see if there was something already built
in Wicket. I am limited to using form submit only no Ajax. Windows CE is
having problems with some of the Ajax I tried to use.
 
Thanks,

Re: Example for presenting pdf in modal window

Just one idea: check that your IDE is not filtering *.pdf files with
the side effect that the file is not available as a resource.

And fyi, I'm using wicket 1.4.6.

My use case is this: I would like to have help pages displayed in my system

outside of my application and just load them whenever a user clicks on a

On your e-mail test.pfd which is not exactly the same as test.pdf?
Maybe that's what is happening? I wrote this longtime ago... So, I

wcall=wicketAjaxPost('?wicket:interface=:1:gettingStartedPanel:step_1:zipcode::IBehaviorListener:0:',
 wicketSerialize(Wicket.$('zip')),function() { }.bind(this),function() { 
}.bind(this), function() {return Wicket.$('zip') != null;}.bind(this));}">

Should I look at submitting the entire form via Ajax when my conditions are 
met? Or any other ideas about how to add a form field to the callback?

Here is what I added to my WebPage:

// Street 1
final TextField street1 = new TextField( "street1" );
street1.setOutputMarkupId( true );
street1.setMarkupId( "address1" );
form.add( street1.setRequired( true ) );

final TextField zipcodeField = new TextField( "zipcode" 
);
zipcodeField.setOutputMarkupId( true );
zipcodeField.setMarkupId( "zip" );
form.add( zipcodeField.setRequired( true ) );

zipcodeField.add( new AjaxFormComponentUpdatingBehavior( "onChange" ) {
private static final long serialVersionUID = 1L;

@Override
public void onUpdate( AjaxRequestTarget target ) {
System.out.println( "Street 1 (final): " + street1.getValue() );
TextField street1f = ( TextField )form.get( 
"street1" );
System.out.println( "Street 1 (form): " + street1f.getValue() );
System.out.println( "Zipcode value (form component): " + 
getFormComponent().getModelObject() );
}

@Override
protected IAjaxCallDecorator getAjaxCallDecorator()
{
return new AjaxCallDecorator()
{
private static final long serialVersionUID = 1L;

@Override
public CharSequence decorateScript( CharSequence script )
{
// Only return the script (which means that it will be 
executed) after the
// user enters the 5th digit (or more)
return "if(this.value.length >= 5){" + script + "}";
}
};
}
});


...and on another note, I had the same code with an OnChangeAjaxBehavior and 
the callback was made when the 5th character was typed, but with the 
AjaxFormComponentUpdatingBehavior the callback was made when the component lost 
focus .. 

Thanks
Steve

Some of them are already implemented, other have a comment below
forwarding to a solution provided somewhere else (e.g. ImageBundle)

an interface for page ?

[Joseph Pachod]

hi

I need to create some page factory where some page should extend some 
specific interface.


Ideally, I would like to be able to request for  
with MyInterface implementing the page interface


however, currently, Page is a class.

Would it be thinkable (for example for wicket 1.5) to have an interface 
for page, which would be used as well in setResponse(..) ?


thanks in advance

Strange error

Hi!
My application uses wicket-1.4.7. I've noticed recently in logs the

No Redirect to login page

[Kruff]

Hi to all,

i am in my second try with swarm to get an secure web application. After the
first example which works fine i started my real application. I use to have
a none secure start page (extends WebPage) which links to some
SecureWebPage. But when i click on the Link to get to the SecureWebPage the
server delivers the page without any authentication. So no login page is
shown and the secure content is shown to everybody. 

I done following steps:

1. Extend App to SwarmWebApplication
2. Create an hive file and register (content see on footer)
3. Extend Secure Pages to SecureWebPage
4. Create a login page and register to application (getLoginPage)

At the moment there is no error message or anything else to hint me why no
login is shown for the securewebpage.

Hope someone can give me a hint to get a step further.

Best regards

Kruff

hive content:

grant principal
org.apache.wicket.security.hive.authorization.SimplePrincipal "admin"
{
permission ${ComponentPermission} "my.web.SourceControl", "inherit,
render";
permission ${ComponentPermission} "my.web.SourceControl", "enable";
};

RE: Wicket DatePicker memory leak during ajax rerender?

[Jomar Lorentzen]

Bumping this.

Have anybody experienced memory leaks on the client when rerendering 
datepickers using wickets AjaxRequestTarget#addComponent()?

Subject: Wicket DatePicker memory leak during ajax rerender?

Hi,

we are using the DatePicker in a panel that is rerendered through ajax at a 
certain interval, and we have noticed
that the DOM reporter in firebug reports that a new function is added each time 
the DatePicker is rerendered. As none
on our team are really into javascript we're wondering if anybody could say if 
this is a potential memory leak?

Each time the DatePicker is rerendered a new random javascript function of the 
type initdateXXX is added to the page. Are these
initXXX references a potential memory leak on the browser, or would they be 
cleaned up by the browser if firebug had not been running?

initdate838 = function() {
Wicket.DateTime.init( ... );
};


if (wicketCalendarInitFinished) {
// when a DatePicker is added via ajax, the loader is already finished, so
// we call the init function directly.
initdate838();
} else {
// when page is rendered, all calendar components will be initialized after
// the required js libraries have been loaded.
wicketCalendarInits.push(initdate838);
}

Re: AbstractDefaultAjaxBehavior - getCallBackUrl

[Arie Fishler]

I don't get the difference - Wicket's ajax calls work just fine - they are
all on the page with the wicketAjaxGet() function - the first parameter
which is the URL has the jsessionid

when I generate my JS function which is only used to call the ajax
*

function* myFunction(){

*var* wcall=wicketAjaxGet('${ajaxCallUrl}' , *function*() { }, *function*()
{ });

}

I generate the ajaxCallUrl with getCallbackUrl(*true*) of the behavior

The result is something like

?wicket:interface=:0:homePagePanel:promotionsPanel::IActivePageBehaviorListener:10:&wicket:ignoreIfNotActive=true

With no jsessionid when actually required (cookies not enabled on the client
browser)

The full code of the behavior's onBind that does it

@Override

*protected* *void* onBind() {

Component comp = getComponent();

markupId = comp.getMarkupId();

Map scriptParams = *new* HashMap();

scriptParams.put("ajaxCallUrl", getCallbackUrl(*true*).toString());

scriptParams.put("functionName", getGeneratedFunctionName());

*if* (paramName == *null*)

getComponent().add(*new* ScriptHeaderContributor(AjaxJSFunctionBehavior.*
class*, "ajaxfunction.js", scriptParams));

*else* {

scriptParams.put("paramName", paramName);

getComponent().add(*new* ScriptHeaderContributor(AjaxJSFunctionBehavior.*
class*, "ajaxParamFunction.js", scriptParams));

}

*super*.onBind();

}
