Re: add form components via ajax

[Riyad Kalla]

setMarkupId(true) is used to ensure there is a placeholder generated
in the HTML where the addition of the  (or whatever) will take
place.

You don't set this typically on the form itself, but on a placeholder
inside the form that you probably replace with a MarkupContainer of
some kind with the same name that contained the new form elements that
you wanted to inject.

Re: expecting different behavior from form validation - potential bug?

[Riyad Kalla]

Antoine,

I think this was discussed 3 days ago in the thread titled
"Form#anyComponentError change in 1.4 breaks validation" (Russel
Morrisey), basically noting that in a recent release of Wicket, the
form "onError" behavior was changed to checking for errors on ANY
component in the form, to just Form-based components.

Related JIRA Issues:
http://issues.apache.org/jira/browse/WICKET-2202
http://issues.apache.org/jira/browse/WICKET-2026

And eventually this issue created:
https://issues.apache.org/jira/browse/WICKET-2734


Hope that helps incase you wanted to jump in on any of that.

Resource authorisation scenario: dealing with non-application wide permissions

[Daniele Dellafiore]

Hi.

Imagine this scenario: a webapp that allows creation of groups of people.
There is the owner, the administrator and the normal user for every group.
Like google groups, yahoo groups, facebook groups, a chat... a lot of
examples :)

If we define permission as string concatenation, I can have "group:delete"
as permission.
In this scenario the permission is not application wide, but "group
specific". Is related to the entity of my domain: Group.

Unfortunately I have no idea how to solve my problem in AuthStrategy, where
I can just access the user, not his particular Role in the specific group of
my webapp, I do not have enough information. I can't know in
isActionAuthorized method what is the group to ask authorization access for
"group.delete" permission.
If I know which is the group (domain entity) I can ask the user for the role
he has in the group, and see if it's role has "group.delete" permission.
Or any similar implementation, the point is that I miss an information.

What can be a nice way to solve this problem with Wicket
AuthorizationStrategy?

I have just read a recent article about how to integrate shiro and wicket:
http://blog.tauren.com/2010/01/using-wicket-with-shiro-for.html

My point with that solution is that as far as I know, overriding isVisible()
is a discouraged practice. More over, the visibility control for
authorisation access has better room in the AuthorizationStrategy and if I
remember fine, what change is the isVisibilityAllowed().

I can just figure out to to put that information (the role of the subject in
the group) in the Action, but I have to learn how. Do you think should be a
nice idea? Or maybe I am making my life harder for nothing and setting
visibilityAllowed (or even override that method) would be fine enough?

I think I can save a lot of "ifs" or a lot of override if I Can figure out a
way to implement it the way I described.

I will sleep on this :)

AjaxCallThrottlingDecorator breaks the precondition of AjaxFormSubmitBehavior

[Russell Morrisey]

I ran into a problem with wicket's ajax call throttling in wicket 1.4.5. It 
seems like the AjaxFormSubmitBehavior's precondition script isn't working the 
way it's intended when a throttling call decorator is supplied. It's causing a 
one-off side effect problem in my application in IE7.

 I created a JIRA issue, with a quickstart to demonstrate the bug in FireFox 
(where the symptoms of the problem are easier to understand and debug), and a 
suggestion on what I think the fix should be.

quickstart POM has wrong artifactId for jetty maven plugin

[Russell Morrisey]

I'm using the quickstart maven command generated by 
http://wicket.apache.org/quickstart.html, and then running 'mvn eclipse:eclipse 
-DdownloadSources=true'. I have the wicket version set to 1.4.5.

The build fails:
Unable to find resource 
'org.mortbay.jetty:maven-jetty-plugin:maven-plugin:7.0.0.pre5'.

Consulting my local .m2 repository, I figured out that the artifactId is 
'jetty-maven-plugin'; the quickstart pom says 'maven-jetty-plugin', and I had 
to change it manually in the POM to make it build successfully.

make your button setusedefaultformprocessing(false) and trigger

it has nothing to do with nested forms. regular links do not submit

Hook Before Form Validation on a Button

[Tony Wu]

For form submission I can override onSubmit to do my own processing, but is
there anything I can override that happens BEFORE the form validation? I
need to for example, based on which Button they press, .setRequired(false)
on some components before the form processing kicks in.

I tried @Override validate() to temporarily do nothing, but the form
validation still kicks in. And validateValidators() is final so can't be
overwritten.

Any ideas?

add form components via ajax

[wic...@geofflancaster.com]

I'm trying to add form components to a form using ajax. i've set
"setMarkupId(true);" on the form but when I run it, i get an error saying
"cannot update component that does not have setOutputMarkupId property set
to true. Component: [MarkupContainer [Component id = realTimeForm..."

So basically when someone moves 1 or more selections from the available to
the selected side of the palette, i want it to add another palette to the
form.

Code Snippet:

List valueList = new ArrayList(); // this actually has values 
IChoiceRenderer renderer = new ChoiceRenderer();
Palette palette = new Palette("palette", new Model(new ArrayList()), new
Model(valueList), renderer, 5, false){
@Override
protected Recorder newRecorderComponent() {
Recorder rec = super.newRecorderComponent();
rec.setRequired(true);
rec.add(new AjaxFormComponentUpdatingBehavior("onchange") {
@Override
protected void onUpdate(AjaxRequestTarget target) {
Palette newPalette = new
Palette("newPalette",new Model(new ArrayList()),new Model(new
ArrayList()),renderer,5,false);
target.addComponent(newPalette);
}
});
return rec;
}
};

public Constructor(){
Form form = new Form("realTimeForm");
form.setOutputMarkupId(true);  //enable ajax on the form
form.add(palette);
add(form);
}

Re: images not under the context root directory

[Daniele Dellafiore]

Hi.
I am facing the same problem: user upload images and I want to access
from wicket.
Of course, user resources are not going to stay under the webapp context.
I would prefer also to put this images wherever I want in the file
system, not under the container folder as well.

I have taken some more decisions:
1. user upload in a user subfolder. So I have a main pictures folder
and then pictures/user1, pictures/user2 and so on.
2. I do not want to use an external servlet or ask apache. Maybe there
are good reason to to that, but I can just think at performance
reasons.

Too get images from a custom folder in wicket I found only one way: to
subclass DynamiImagerResource. I override:

protected byte[] getImageData() {}

and there I can access any folder I want on my filesystem with
standard java API.
I would write almost the same code in a custom servlet. But with a
servlet that serve and image if called, say, to:

localhost:9090/myApp/pictures/user1/pic1

would expose an interface to directly access the image, while all
resource access code stay "in wicket" so I have a security issue. This
is also the reason I can't use the solution François Meillet expose,
even if I find a very nice one if one does not have my privacy issue.

My only problem now is that I can't figure out how to get a nice URL
with DynamicWebResource but is the less important of all requirment.

What is your opinion about that? What are potential problems in using
DynamicImageResource to serve an image that is not dynamic, is just
stored in a user related folder?

Re: Wicketstuff versions

[Jeremy Thomerson]

Wicket stuff is a free-for-all with little documentation.  I think
1.4.2-SNAPSHOT was accidentally left in the pom after one of the versioned
builds (because that's what maven defaults to).  But the idea is that
wicketstuff-core modules should match Wicket - so 1.4-SNAPSHOT **should** be
what it's set to right now.

Re: jdbc

[Ivan Dudko]

Thank you.
I already do simple things with hibernate and spring ioc.
Now i want to use plain old jdbc.
I already get the datatable wich works with one pojo (table).
Now i am in trouble.. how i can get table for two joined tables, for example?

Re: jdbc

[James Carman]

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.

expecting different behavior from form validation - potential bug?

[Antoine van Wel]

hi,

In a nested form the onValidate() is overridden.
It sets an error message on a component inside this form - so not on
the form itself.

However the submit on the form itself is executed as if no error
exists. What I see when debugging is that hasErrorMessages on the
inside nested form returns false. Is this correct? Should I explicitly
set an error on the form, or something else to indicate the form
itself has an error?

..using 1.4.6


Antoine.

Re: Form validation without a form component

for the archive-searchers :)

simply override onValidate in the Form class, check your listsize
there & call error() when applicable

TextArea in repeater doesn't update it's model

[Rubén khanser]

I have an AjaxFallBackLink that executes an update in a service, but i need
the textArea of the same row to be updated. I have wasted all morning but i
can't still make it work.

I reached this point:

 DataView dv = new DataView("dataView",ldp) {
 private static final long serialVersionUID = -3315693391867601086L;

@Override
protected void populateItem(Item arg0) {
Label pagina;
 final Label codi;
final TextArea valor;
AjaxFallbackLink link;
 final StringBuffer vBuffer = new StringBuffer();
 final AccTextosWrapper tWrapper = (AccTextosWrapper)arg0.getModelObject();
pagina = new Label("pagina", tWrapper.getPagina());
 codi = new Label("codi",tWrapper.getCodi());
codi.setOutputMarkupId(true);
 valor = new TextArea("valor", new PropertyModel(tWrapper,"descripcio"));
valor.add(new AjaxEventBehavior("onblur") {
 @Override
protected void onEvent(AjaxRequestTarget arg0) {
 String val = valor.getModelObjectAsString();
vBuffer.delete(0, vBuffer.length());
 vBuffer.append((val == null)?"":val);
 }
 });
valor.setOutputMarkupId(true);
link = new AjaxFallbackLink("link") {
 private static final long serialVersionUID = 3439293533625966929L;

@Override
public void onClick(AjaxRequestTarget arg0) {
 String c = codi.getModelObjectAsString();
 adminService.updateTextDescripcio(c,vBuffer.toString());
  }
};
link.setOutputMarkupId(true);
  arg0.add(pagina);
 arg0.add(codi);
arg0.add(valor);
arg0.add(link);
 }
};

If i don't use validate() and updateModel() i get the same string i had at
the start otherwise i get null.

All works fine but the TextArea model.
Thank you very much for your help

Wicketstuff versions

[Charles Deal]

I'm a little confused about the versioning for Wicketstuff.  I am currently
using inmethod-grid, jquery, and yui.  All three projects now have a
1.4-SNAPSHOT and a 1.4.2-SNAPSHOT version and (inmethod-grid and yui both
have a 1.4.1 release version).  What is the difference between the two
SNAPSHOT versions?  I tried searching on it and looking at the Wicketstuff
Wiki, but could not find an explanation.  Which should we be using?

Wicket MashUpContainer

[Martin Makundi]

Hi folks!

In web development, a mashup is a web page or application that
combines data or functionality from two or more independent components
or sources to create a new view or service.

The term mashup implies easy, fast, snap-on integration. If the mashup
sources are from independent applications, integration can be done via
open APIs or data sources. However, if the mashup sources are native
to the development framework, native interfaces can be used.

Mashups are used to allow producing results that extend the original
purpose of producing the source component, service or data.

The actual ”mashign up” can occur at runtime or at compile time.
However, the more flexible it is the moer ”mashup style” it is. One
well known example of mashups is Google Maps: the map is an
independent source and one can mash-it-up with various labels, pins,
position indicators, route indicators, etc.

Few mashup articles on the web:
* http://en.wikipedia.org/wiki/Mashup_%28web_application_hybrid%29
* http://www.esri.com/software/mapping_for_everyone/api/mashup.html
* http://code.google.com/intl/fi-FI/gme/

As a simple example of creating a mashup using wicket, I will use
simple web page layout. As sources we will have components such as
header, menu, footer, and content.

The mashup will be introduced onto a page that aggregates these
contents "on-demand".

Here goes the example, and ofcourse discussion about the pros and cons
of the approach is welcome!

In addition to the snipplet posted here, full source code is available
at http://code.google.com/p/wicket-mashup/

:::

public class HomePage extends MashupWebPage implements IHeaderContributor {

/** */
private static final long serialVersionUID = 1L;

public void renderHead(IHeaderResponse headerResponse) {
  headerResponse.renderString(" div.content {
margin: 20px; height: 250px;   }");
}

public HomePage() {
add((Panel) new HeaderPanel(GID));
set(1, (Panel) new StyledMenuPanel(GID) {
@Override
public void setSelectedTabPanelContent(Panel newInstance) {
  HomePage.this.set(2, newInstance);
}
});
add((Panel) new FooterPanel(GID));
  }
}

:::

Awaiting for feedback, discussion, and suggestions for improvement,
Martin
:)
