catch jquery event at AjaxEventBehavior

[Lurtz Nazgul]

Hi; 

I used jquery dialog. I can open and close jquery dialog box. I represent 
jquery 
dialog as a panel at wicket side.

My question is how can i catch jquery close event ? 

I tested like below but it doesn't work

dialogConfirmation.add(new AjaxEventBehavior("close") {
  @Override
  protected void onEvent(AjaxRequestTarget target) {
  System.out.println(" closed" );
  }
}) ;

Thanks.

Re: Scala DSL for Wicket

[Gary Thomas]

I've written some Scala utilities as well, but instead of a DSL I'm 
using implicit conversions via traits, which I've found to be a really 
nice fit with Wicket.


An example:

import org.apache.wicket.model.IModel
import org.apache.wicket.model.LoadableDetachableModel
import org.apache.wicket.model.PropertyModel

trait WicketConversions {
   // transparent PropertyModel conversion
implicit def tuple2model[T](tuple: (AnyRef, String)): 
PropertyModel[T] = {

new PropertyModel[T](tuple._1, tuple._2)
}

// transparent function/closure to LoadableDetachableModel conversion
implicit def function2model[T](f: => T): IModel[T] = {
new LoadableDetachableModel[T] {
def load: T = f
}
}
}

Usage:

class MyPanel extends Panel("id") with WicketConversions {

// transparent PropertyModel conversion using article.rating):
add(new RatingPanel("rating", article -> "rating") // so pretty

// transparent LoadableDetachableModel conversion (expects 
IModel[Boolean]):

add(new AjaxCheckBox("selected", { dao.get(id).isAdmin }) {
def onUpdate(target: AjaxRequestTarget) { ... }
})
}


I have more code as well for Spring integration, etc.
If anyone is interested, I could add mine to this or to a new GitHub 
project.



Thanks,
Gary

Bruno,

Yet another idea for the dsl:

def ldm[R, ID](id: ID = null, f: (ID) =>  R) = {new
LoadableDetachableModel(id) { override def load() : R = { f(id); } } }

P.S. Not tested.

Thanks Martin,

There was only a small little problem in your code. The correct syntax

is:


def label[T](id: String, model: IModel[T] = null): Label = { val label
= new Label(id, model); add(label); label }

The suggestions were updated on Gist.

Idea for simplification: use named parameters.
For example
def label[T](id: String, model: IModel[T]): Label = { val label = new
Label(id, model); add(label); label }
would become
def label[T](id: String, model = _ : IModel[T]): Label = { val label =
new Label(id, model); add(label); label }

this way you'll have just one declaration of label function which will
handle the current three

additionally you may add a pimp:
implicit def ser2model[S :<  Serializable](ser: S): IModel[S] =
Model.of(ser)

now even when you pass String as second param to label() it will be
converted to IModel

Hi

actually for testing , i tried using the new kryo-serializer from wicket

IT DOES NOT WORK, actually it has many more errors than the default one,
actuallly it cannot serialize a JdkDynamicProxy which is the basis for

Re: serialization problem with spring

[Joe Fawzy]

Hi

i am living on the edge ,using wicket 1.5RC5.1 (the latest)
and also using the newly released Spring data-jpa project for data access

i do not use or reference PersistenceExceptionTranslationInterceptor
directly, actually i never know it is there  till i saw that error

based on its name it is an interceptor which translate the jpa or jdbc
exception to spring's counterpart

in AccountManager there is an instance of AccountDAO which use this
persistence technology

i thought it might be a solution to use kryo serialization as it does not
require the object to be serializable, but the site does not recommend using
it in production as it is in its early stages and not yet stable

Any help please?

Thanks

Joe

Re: Manually Rendering a DataGridView

[Pedro Santos]

The char sequence is returned by mockResponse.getText()
Sure, there are no public methods and would be a good idea to
refectory the code and move the mock response logic to other place.
You can use an IVisitor to visit cells in you component tree,  create
a mock response to render them and use its text, i.e.
mockResponse.getText(), to fit your needs

Re: serialization problem with spring

[Dan Retzlaff]

Hi Joe,

Based on the depth of that serialization stack, I doubt it's your
AccountManager proxy that's giving you problems. I usually just breakpoint
NotSerializableException and walk up the stack to find the culprit. Any
change your CreatePage uses a method on AccountManager that returns an
object with PersistenceExceptionTranslationInterceptor, then holds a
reference to it? If so, that'll be a problem since Wicket doesn't know to
proxy that one.

Re: Scala DSL for Wicket

[Bruno Borges]

This is an excellent piece of code.

What I had was similar, but in a trait as a method:

def ldm( loadF() => T ): IModel[T] = {
   ...
}

I guess breaking the DSL will make it easier to maintain. :-) And your
approach is much better

Re: serialization problem with spring

[Bruno Borges]

What version of Wicket are you using?

On older versions you must declare your field as transient.

Newer versions don't required this anymore.

serialization problem with spring

[Joe Fawzy]

Hi
i have a serialization problem with spring
My CreatePage class looks like:-

public class CreatePage extends WebPage{
@SpringBean
AccountManager accountManager;
}

as i am using @SpringBean , it should handle creating a serializable proxy
for me BUT

i got the following exception



ERROR - JavaSerializer - Error serializing object class
com.app.view.account.CreatePage [object=[Page class =
com.app.view.account.CreatePage, id = 1, render count = 1]]

 Hi,

 this is just a wild guess but in your code you have line that calls
 "item.remove(listChoice);" under certain conditions and the listChoice
 instance is bound to the category identifier which does not seem right to
 me.

 As far as I understand ListViews the associated markup block is created for
 each item. If you remove the listChoice from an item then Wicket has no
 object to associate the markup with. So I think you cannot remove the 
 choice
 that way.

 I have a similar use case where I also add and remove objects to and from
 ListViews via Ajax and it was sufficient to just remove the object from the
 collection that the ListView relies on and add the wrappign container to 
 the
 ajax target.

 Since the listChoice is the only thing you add to an item I figure that
 could also be feasible for your case but as said before this is just a
 hunch.

Re: on the fly components

[ramazan pekin]

I removed "item.remove(listChoice);" from code and I just changed
ListView definition, I used PropertyModel, and every thing working
well...

listView = new ListView("categoryList", categories) {
-> I changed this line as below
 => listView = new ListView("categoryList", new
PropertyModel>(this, "categories")) {

Re: Updating a Component from anywhere

You're thinking about it the wrong way: you should ask how do I let
this label (or panel) know about an ajax event happening?

Queue wicket 1.5's event mechanism:

Re: on the fly components

[ramazan pekin]

Actually, as you said, when I add new bounded object to the collection
new listChoice has been added to page, but whenever I tried to remove
object from collection, related listChoice is not being removed from
page. I have added wrapping container and I specified as target
component to listChoice's onchange action. As result, I have added
"item.remove(listChoice);" to code but this time, exception raised.

I think I am using ListView wrongly, main problem looks like ListView
related model object. This is my current markup file content.

Re: Updating a Component from anywhere

[eugenebalt]

Essentially what I'm asking is, is there an easy way to find a component,
among the entire current tree of all components included or cross-included
in the final page, from anywhere in the code.

Updating a Component from anywhere

[eugenebalt]

I have a Panel containing a Label that shows how many items are in the
shopping cart right now.

The Label should be updated (via Ajax) from within any number of pages,
forms, and panels throughout the application. Various sub- and
sub-panels/forms/etc. may have the "Add To Cart" link that should update
this Label, so the Ajax update can come from various points.

The Panel with this Label is always displayed at the top of every page.

My question is, is there an easy way to save as a "global variable" this
Label component (or, the containing Panel) so it's available to everybody
all the time? Thanks.

Re: Form Model Not Available for AjaxFallbackLink

[vineet semwal]

second suggestion is good too ,you will have to specify the js event
say onchange/onblur for ajaxformcomponentupdatingbehavior
when that even will be fired,your model will be updated with the new
value,you dont have to use ajaxsubmitlink in that case..

 it depends on which way you want to do..

The first suggestion worked. Thanks. 

Regarding AjaxUpdatingBehavior, yes my component was Ajax, but the data was
not binding to the model at the time of the click because we weren't
submitting the form. I needed to read the value entered for one of the
components and it wasn't available at that time.

Re: on the fly components

[Christian Huber]

Hi,

this is just a wild guess but in your code you have line that calls 
"item.remove(listChoice);" under certain conditions and the listChoice 
instance is bound to the category identifier which does not seem right 
to me.


As far as I understand ListViews the associated markup block is created 
for each item. If you remove the listChoice from an item then Wicket has 
no object to associate the markup with. So I think you cannot remove the 
choice that way.


I have a similar use case where I also add and remove objects to and 
from ListViews via Ajax and it was sufficient to just remove the object 
from the collection that the ListView relies on and add the wrappign 
container to the ajax target.


Since the listChoice is the only thing you add to an item I figure that 
could also be feasible for your case but as said before this is just a 
hunch.


HTH, Chris

Re: on the fly components

[Rodrigo Heffner]

Hi Ramazan,

I'm also very new to wicket, and I've came across a similar situation too.

I solved my situation by using different panels with the same markup
id. Something like (inside the populateItem method):

if (condition == true) {
item.add(new SomePanel("sameId"));
} else {
item.add(new AnotherPanel("sameId"));
}

In this way, in your markup you'd have something like



and you could have completely different panels.

Let me know if this helps or if you find a better way

Yes,

In IE 8, using Wicket 1.4.9, even with javascript enabled, I get a POST

have broken ajax (because of the transport), but I also don't get a fallback

I'm thrilled if the fault lies with me, because that's presumably easier to
fix. But what am I (not) doing that breaks this?

Ajax sort-of works: the the Wicket Debug "window" doe show up, and when
the

This looks like the same bug as reported in
https://issues.apache.org/**jira/browse/WICKET-3887and
https://issues.apache.org/**jira/browse/WICKET-1432.
It's apparently fixed in
1.5, but while bug 3887 is claimed to be fixed in 1.4.18, the latest
snapshot exhibits the same behavior as 1.4.17.

Re: Form Model Not Available for AjaxFallbackLink

[Rodrigo Heffner]

I had the same question last week. This is probably what you want:
http://wicket.apache.org/apidocs/1.4/org/apache/wicket/ajax/form/AjaxFormComponentUpdatingBehavior.html
.

Add this to your component and it's model will be updated without submitting
the form.

Form Model Not Available for AjaxFallbackLink

[eugenebalt]

I have a TextField and an AjaxFallbackLink. The AjaxFallbackLink, when
clicked, must read the value of the TextField. But that value isn't
available yet, because there has been no form submit and no model binding
yet.

Both getInput() and getModelObject() return NULL at the time of the
AjaxFallbackLink's click. Any ideas how to solve that?

Thanks

Re: Manually Rendering a DataGridView

[Matt Schmidt]

So after calling tableParser.parse(myDataGridView), how do I get the the
char sequence? Or iterate over each row to get the char sequence for each
cell? I don't see any public methods for that.

Re: RFC: Ten things every Wicket programmer must know?

[samket]

Knowing what my co-workers are like, these are the most important things that I 
say to them. So this list is directed towards them in particular.

1. When receiving parameters in a constructor or method, a model (an instance 
of IModel) is almost always the right choice instead of a raw model object. 
Almost everyone here has mentioned this rule in different words (probably most 
better than mine).

2. Apply your generic object-oriented programming skills to web page 
programming. When dealing with pages and panels, know when to use inheritance 
and when not to. Inheritance is something you should usually try to avoid and 
use composition instead. Inheritance might save you a couple lines of code but 
it tends to make the code crazy difficult to understand. Having said that, it 
must be mentioned that there are plenty of situations where using inheritance 
is justified. I just think the cost of using inheritance in the wrong place is 
so high that it deserves to be feared.

3. A page's markup must be kept very clean. It should never be no more than 50 
lines, or so. Use panels to separate parts of the page. A (positive) result of 
this is that the page's java file is probably clean too. The main reason for 
this rule is that it should always be easy for everyone to get an idea of the 
general structure of a page.

4. When a markup contains a wicket:id, the corresponding java file should 
probably contain a corresponding add-method invocation. I.e. the corresponding 
add-method invocation shouldn't be located in some other (unrelated) java file. 
For understandability's sakes.

5. Don't be afraid to refactor source codes. Even those that were originally 
made by someone else. There are plenty of reasons why this is important. One of 
them is that nobody makes perfect code the first time. You shouldn't even try 
to make perfect code the first time. It's usually fine if you make monolithic 
panels (not pages), use plenty of inner classes and make inefficient code. They 
will be refactored later if they are modified often and if people adhere to 
this rule.

6. With Wicket as the web application framework you rarely if ever need to 
create servlets. File downloading is possible with resources and it's possible 
to create bootstraps too. Okay, this rule doesn't deserve to be in the top 10, 
but I seriously don't want to see more servlets being made - EVER! :)

7. It's pretty important to learn about all the different types of models. They 
may be a little more difficult concept to understand than components.

8. WebMarkupContainer is a simple yet useful component that does nothing unless 
you program it do something. WebComponent is equally simple but less often 
useful because it can't be a parent to other components.

Hello all,

 I'm writing an article for a Java magazine and would like to include in it
a list of "ten things every Wicket programmer must know". Of course, I have
my list, but I'd be very curious to see what you think should be on that
list from your own experience. Or, put another way, maybe the question
would be "what I wished I knew when I started Wicket" - what tripped you up
or what made you kick yourself later?

 Please reply back if you have input. Please note that by replying, you
are granting me full permission to use your response as part of my article
without any attribution or payment. If you disagree with those terms,
please respond anyway but in your response mention your own terms.

Best regards,
