Authorization and

[Wilhelmsen Tor Iver]

We have an app with three "user types" and two "user levels" (read  or 
read-write in effect). We want to use these in authorization, and thought about 
an approach using annotations. However, at the point of the Wicket auth. 
interface methods, only class-targeted annotations are visible, and that will 
lead to excessive subclassing (especially since Java does not let you annotate 
anonymous inner classes).

Would it be a better approach to use "behaviorless Behavior" objects that we 
add to the relevant components and look for in isActionAuthorized()?

modal in a modal problem

[Martin Asenov]

Hello, everyone!

I experience a problem when triggering a modal window from another modal 
window. When a removal icon is clicked in the first modal, there's a 
confirmation dialog, that pops up. Although I've set everything up, the 
windowClosedCallback gets activated only when I confirm removal twice. I have 
no idea why it happens this way. The confirmation dialog works fine for all 
RepeaterHoldingPage-s I have, excluding the one I have placed in another modal. 
Here's the code of the conf dialog:

   public ConfirmationDialog(String question, final ModalWindow parent, 
final RepeaterHoldingPage page, final Object entry) {

 System.out.println("confirmation dialog called");

 questionLabel = new Label("question", question);
 yesButton = new AjaxButton("yes_button", new 
Model(getString("yes"))) {

private static final long serialVersionUID = 1l;

@Override
protected void onSubmit(AjaxRequestTarget target, Form 
form) {
   System.out.println("yes button clicked");
   parent.setWindowClosedCallback(new 
ModalWindow.WindowClosedCallback() {

  private static final long serialVersionUID = 
1L;

  @Override
  public void onClose(AjaxRequestTarget target) 
{
page.removeItem(entry, target);
System.out.println("removal supposed to 
be called");
  }
   });

   parent.close(target);
}
 };

What happens is that I trigger the conf dialog, press the 'yes' button and in 
the console the following gets printed:
confirmation dialog called;

RE: modal in a modal problem

[Martin Asenov]

I forgot to mention that the first time I click yes, I get:

confirmation dialog called
yes button clicked

in console, and the conf dialog closes itself. when I open it for second time, 
I get
confirmation dialog called
yes button clicked
removal supposed to be called

and the item really gets removed, but why triggering it twice?

Thanks in advance!

Re: quickstart POM has wrong artifactId for jetty maven plugin

[Martijn Dashorst]

It works perfect for 6.x releases. You changed the version to 7 your
self, so it is your responsibility to change the other stuff  too.
When we upgrade the version we'll be sure to modify the plugin
accordingly.

Re: jdbc

[Ivan Dudko]

For example..
class Honey {
int id;
int milkid;
String name;
// getters and setters
}
class Milk {
int id;
String name;
// getters and setters
}

and my query:
SELECT honey.id ID, honey.milkid MILKID, honey.name HONEYNAME,
milk.name MILKNAME FROM honey, milk
WHERE  honey.milkid=milk.id;

And i want to display table with these fields.

Which object i must use?

Re: Authorization and

[Daniele Dellafiore]

I am facing authorization problems this days, as you see in onother message.


when I started to deal with this problem I were also uncomfortable at the
idea to use annotation on components or even specific class (like
SecureComponent). Too much noise in the code and too much interference of
authorization stuff in the operational code.

I wanted to move everything in the AuthorizationStrategy to keep the
panels/page code almost authorizazion unaware.

Actually I think that that target could be achieved only for some simple
situation. My advice is to try using the wicket component.setMetaData. You
can put there you access authorization key and check for it in
AuthorizationStrategy.

This is easy to understand and keep the code clean.

Re: jdbc

[James Carman]

You could create a reference from Honey to Milk, since you have a
"milkid" field there.  Then, you'd use a list of Honey objects and
you'd display these properties:

id
milk.id
name
milk.name

 Yeah, but this doesn't give them an example of how to get the results
 out of a JDBC result set.  This is based on a static, in-memory list
 of Contact objects.  What I would recommend is to look at a
 Hibernate-based example and come up with the JDBC analog.  Here's an
 example from my Advanced Wicket talk I gave a while back:

 http://svn.carmanconsulting.com/public/wicket-advanced/trunk/src/main/java/com/carmanconsulting/wicket/advanced/web/story3/page/Home.java

 At the bottom, there's a data provider which talks to a "repository"
 to get its data.

How to disable AJAX call on ModalWindow close

[zkn]

Hi,

I'm using 

Wicket.Ajax.registerPreCallHandler(showBusyScreen);
Wicket.Ajax.registerPostCallHandler(hideBusyScreen);
Wicket.Ajax.registerFailureHandler(hideBusyScreen);

to show and hide a busy screen on the page while executing AJAX calls. But it 
also shows up when I click the close button of a modal window even though I 
don't need to do anything on the server side.
Is there are way to disable this AJAX call on modal window close?

I forgot to mention that the first time I click yes, I get:

in console, and the conf dialog closes itself. when I open it for second time, 
I get

and the item really gets removed, but why triggering it twice?

Subject: modal in a modal problem

Hello, everyone!

I experience a problem when triggering a modal window from another modal 
window. When a removal icon is clicked in the first modal, there's a 
confirmation dialog, that pops up. Although I've set everything up, the 
windowClosedCallback gets activated only when I confirm removal twice. I have 
no idea why it happens this way. The confirmation dialog works fine for all 
RepeaterHoldingPage-s I have, excluding the one I have placed in another modal. 
Here's the code of the conf dialog:

   public ConfirmationDialog(String question, final ModalWindow parent, 
final RepeaterHoldingPage page, final Object entry) {

 System.out.println("confirmation dialog called");

 questionLabel = new Label("question", question);
 yesButton = new AjaxButton("yes_button", new 
Model(getString("yes"))) {

private static final long serialVersionUID = 1l;

@Override
protected void onSubmit(AjaxRequestTarget target, Form 
form) {
   System.out.println("yes button clicked");
   parent.setWindowClosedCallback(new 
ModalWindow.WindowClosedCallback() {

  private static final long serialVersionUID = 
1L;

  @Override
  public void onClose(AjaxRequestTarget target) 
{
page.removeItem(entry, target);
System.out.println("removal supposed to 
be called");
  }
   });

   parent.close(target);
}
 };

What happens is that I trigger the conf dialog, press the 'yes' button and in 
the console the following gets printed:
confirmation dialog called;

No point using a submit link if you are going to override onclick with

Palette selected item

[Josh Chappelle]

I have a Palette component that I need to be able to fire an event when an
item on the right side(selected side) has been clicked. Additionally I need
to know what item was clicked because I'm going to be populating another
panel based on that click. 

 

I have created my own component called SelectableOptions that extends
AbstractOptions and implements IOnChangeListener. Then I took the
implementing code that is in DropDownChoice(since it is a good example of a
component that implements IOnChangeListener) and put it in my component. 

 

I am able to receive the onSelectionChanged event and I'm able to pass the
object that the user clicked to that method. However, when you click the
option and the event is fired, a full post back happens and all the items on
the right side of the palette is lost. Basically the component is
re-initialized. 

 

Can anyone help guide me in the right direction? I have posted the code
below:

 

public class SelectableOptions extends AbstractOptions implements
IOnChangeListener

{

public SelectableOptions(String id, Palette palette, IModel
selectionModel)

{

super(id, palette);

setModel(selectionModel);

}

 

protected void onComponentTag(final ComponentTag tag)

{

checkComponentTag(tag, "select");

 

CharSequence url =
urlFor(IOnChangeListener.INTERFACE);

 

Form form = (Form)findParent(Form.class);

if (form != null)

{

RequestContext rc =
RequestContext.get();

if (rc.isPortletRequest())

{

// restore url back to real
wicket path as its going to be interpreted by the

// form itself

url =
((PortletRequestContext)rc).getLastEncodedPath();

}

tag.put("onchange",
form.getJsForInterfaceUrl(url));

}

else

{

// TODO: following doesn't work with
portlets, should be posted to a dynamic hidden

// form

// with an ActionURL or something

tag.put("onchange",
"window.location.href='" + url + (url.toString().indexOf('?') > -1 ? "&"
: "?") + getInputName() + "=' + this.options[this.selectedIndex].value;");

}

 

super.onComponentTag(tag);

IValueMap attrs = tag.getAttributes();

 

String onFocus =
getPalette().getSelectionOnFocusJS();

if (onFocus != null)

{

attrs.put("onFocus", onFocus);

}

//  tag.getAttributes().put("ondblclick",
getPalette().getRemoveOnClickJS());

}



protected void onComponentTagBody(MarkupStream markupStream,
ComponentTag openTag)

{

final AppendingStringBuffer buffer = new
AppendingStringBuffer(128);

Iterator options = getOptionsIterator();

IChoiceRenderer renderer =
getPalette().getChoiceRenderer();

 

while (options.hasNext())

{

final Object choice = options.next();

String id = renderer.getIdValue(choice,
0);

Object displayValue =
renderer.getDisplayValue(choice);

Class displayClass = displayValue ==
null ? null : displayValue.getClass();

String value =
getConverter(displayClass).convertToString(displayValue, getLocale());

value = getLocalizer().getString(id +
"." + value, this, value);

 

buffer.append("\n").append(value).append("");

 

}

 

buffer.append("\n");

 

replaceComponentTagBody(markupStream, openTag,
buffer);

}

 

 

@Override

protected Iterator getOptionsIterator()

{

return getPalette().getSelectedChoices();

}

 

public final void onSelectionChanged()

{

Iterator iter = getOptionsIterator();

System.out.println("Still here");

while(iter.hasNext())

  

BookmarkablePage with PageParameters

[Pierre Goupil]

Good evening,

I have a BookmarkablePage which may need PageParameters or not, depending on
the business workflow. I used to mount it under /page but now that we do use
the PageParameters-providing constructor I have a problem which forced me
not to mount the page in my Application class anymore.

When I mounted the page explicitly, the PageParameters constructor call used
to gave such an URL: /page/param/0. So when asking for a resource on that
page, it gave me this error message: "URL fragment has unmatched
key/valuepairs, responding with 404".

If I don't mount the page, the URL generated is of the form:
/bookmarkablePage?class=foo¶m=0. Which is good regarding the parameter
retrieval.

My question is: is there any way to have the best of both world, I mean such
a pretty URL as /page (no Java class name in the URL) and the parameters
using the classical '?' and '&' symbols? Which would give this URL:
/page?param=0. I guess that if I don't have any trailing slashes in the URL,
the "URL fragment" message should be avoided, isn't it?

Thanks in advance and regards,

Pierre

Scroll to Anchor on Form Submit

[Tony Wu]

Is there a way in Wicket for Button form onSubmit to refresh the page and
scroll to a particular anchor? For example if I have 3 separate forms with a
FeedbackPanel in each, if I click the submit button for the final form and
there's a validation error, when the page refreshes the error messages are
at the bottom. It's not apparent to the user anything happened unless they
manually scroll down. It would be great if there's a way to scroll to
href="#someanchor". I think there's a setAnchor function in wicket, but
that's only for Links. Is there anything that works for Buttons/Form
submission?

I think you're exactly right to use the

In firefox it works well and when i try to save it, i get the image as 'png'.

Someone know what should i set for explorer to know the type of the image ?


When it renders the image tag has this format:



So i guess the problem is in the 'src' attribute


Any help will be appreciated..

Re: Scroll to Anchor on Form Submit

[Riyad Kalla]

Tony,

I'm not sure if you can mess with the URL (e.g. append a #errors) from
within Wicket without causing a redirect (and loosing your errors from the
request and form state) -- someone smarter than me can address that -- but
if you wanted to get creative, maybe in the onError handler your can
contribute a behavior of some 'window.onload' JavaScript to the body of the
page that does a 'window.location=#errors' or somethig like
that, so as soon as the page comes back up, the JS "redirects" to the exact
same page but an anchor on it.

Not sure if that would cause a redirect or not...

RE: quickstart POM has wrong artifactId for jetty maven plugin

[Russell Morrisey]

Martijn,

I encountered this error without making ANY changes to the POM generated by the 
quickstart archtype command, when running mvn eclipse:eclipse 
-DdownloadSources=true. The artifact it is having trouble with is the maven 
jetty plugin, not jetty itself. The POM has jetty.version 6.1.4 defined at the 
bottom. If I have some other environment setting that is specifying the plugin 
version, I'm not aware of it. Maybe you could give me some direction on where 
to look? I'm not a very experienced maven user.

It works perfect for 6.x releases. You changed the version to 7 your

When we upgrade the version we'll be sure to modify the plugin
accordingly.

OnChangeAjaxBehavior: nth character

[Steven Haines]

Hi,

I
would like to add AJAX behavior to an application that sends an update
to my application after a certain number of characters have been typed.
For example, if the user is entering a zipcode, I would like a callback
to my application to be made after the user enters the fifth character.

I've
written code using OnChangeAjaxBehavior that sends messages back to my
application after every character has been typed, such as the following:

final TextField zipcodeField = new TextField( "zipcode" );
form.add( zipcodeField.setRequired( true ) );
OnChangeAjaxBehavior zipcodeUpdated = new OnChangeAjaxBehavior() {
  @Override
  protected void onUpdate( AjaxRequestTarget target ) {
System.out.println( "Zipcode value: " + 
zipcodeField.getDefaultModelObjectAsString() );
  }
};
zipcodeField.add( zipcodeUpdated );


I
could check to see the size of the zipcodeField (in this example), but
it makes my application more chatty than it needs to be. I also tried
using onblur, which works fine, but does not satisfy my business
requirements:

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

  AjaxFormComponentUpdatingBehavior zipcodeOnBlur = new 
AjaxFormComponentUpdatingBehavior( "onblur" ) {
  @Override
  protected void onUpdate( AjaxRequestTarget target ) {
  System.out.println( "Zipcode value (form component): " + 
getFormComponent().getModelObject() );

Prior
to using Wicket (which I'm currently prototyping for my company), we
would handle this logic in JavaScript (observe changes to the field and
when the user enters the fifth character then we made an AJAX call back
our Struts 2 application.) 

What is the best way to achieve the same end using Wicket?

Thanks, in advance, for your help!
Steve

P.S.
I started using Wicket as part of an article series (because of all of
your passion for it) and I have to say all of you are doing incredible
work - I love it.. Here's the link to the article series in case any of
you are interested:

Re: OnChangeAjaxBehavior: nth character

[vineet semwal]

you can do the same thing with wicket ie. on 5th char typed,make a
ajaxcallback to wicket,

1)you need to add behavior to component and implement it's respond method
the way it suits your need.
2)in the js part you  will make a callback on 5th char typed,callbackurl you
will get from the behavior you
added to the component.
take a look at

results of WebApplication.getConfigurationType() should be cached to avoid synchronization

[Nikita Tovstoles]

Below stack trace indicates that getConfigurationType() is called a lot. It,
however, consults a Hashtable, thereby hitting a synchronized block every
time. Note the resulting wait time (in seconds).

My fix is to cache the value in my WebApplication subclass (and populate
this tiny cache eagerly during app's init()):

/**
 * caches results because by default wicket consults System properties
(ie
 * hits a synchronized block in hashtable)
 */
@Override
public String getConfigurationType()
{
// not making this method synchronized because we'll call it during
init
// to cache the result

if (configurationTypeCache == null) {
configurationTypeCache = super.getConfigurationType();
}
return configurationTypeCache;
}

Using 1.4.3

Re: OnChangeAjaxBehavior: nth character

[Riyad Kalla]

Vineet is exactly right, just to further flesh it out:

You want to add a subclass of AbstractDefaultAjaxBehavior to your page, this
automatically contributes the wicket-ajax.js file to your page which exposes
these JavaScript methods for you:

===
function wicketAjaxGet(url, successHandler, failureHandler, precondition,
channel)
and
function wicketAjaxPost(url, body, successHandler, failureHandler,
precondition, channel)
===

(paraphrased from Wiki)

The part I'm not clear on is which URL do you call with the JavaScript and
which method on the server side is intercepting the GET (or POST)?

That information seems to be missing from the wiki unless it's easier than I
realize and I'm overthinking this...

Re: OnChangeAjaxBehavior: nth character

[vineet semwal]

Riyad,
1)url is callbackurl you will get from
abstractdefaultajaxbehavior.getcallbackurl()
2)method you need to implement is the abstractdefaultajaxbehavior's respond
method

Re: OnChangeAjaxBehavior: nth character

[Igor Vaynberg]

you can use an iajaxcalldecorator to add javascript before the call is
made and interrupt it by simply "return true" until fifth character
has been pressed.
