[Wicket-user] Creating Panels inside of Loop (Wicket 2)

[Stefan Lindner]

I have a Panel that looks like this (html)
 


 
 Place menus here
 



Now I want to generate Panels for wicket id "menu" like this
 
  new Loop(this, "menus", menus.size()) {
   private static final long serialVersionUID = 1L;
   @Override
   protected void populateItem(LoopItem item) {
final int index = item.getIteration();
final Menu menu = MenuBarPanel.this.menus.get(index);

new MenuPanel(?, "menu", menu.getModel(), menu.getMenuItems());
 
I can't use the item for ? because it's not a markupContainer. So, what is 
the correct MarkupContainer for the panels?

[Wicket-user] Fw: Shades phonebook example complete

[Geoff hendrey]

Hi Everyone,

I just finished implementing the phonebook example using Shades. I really like 
the way the phonebook example abstracted everything so I could just plug shades 
in. How can I contribute back the code?

Also, would it be possible to update the phonebook example to HSQLDB 
1.8.0.2.jar? (The LIMIT syntax described in the HSQLDB docs does not work with 
the older version of HSQLDB that is distributed with the phonebook example).

I am loving the way Shades works with Wicket. I think the Serializable 
DatabaseSession in Shades could provide some significant performance 
improvements for Wicket applications beyond what is possible with JDO apps, 
because of the fact that the jdo PersistenceManager is not serializable (thus 
forcing queries by ID when sessions are deserialized).

Anyway, "nice job" to the guys who built the phonebook example. I whish the JDO 
compatibility test kit had had something like it, which would have insured the 
use cases were "real world".

Re: [Wicket-user] ajax refresh on date picker

[samyem]

I could trace my problem to a recent change in wicket-ajax.js. In the
defination of processNext, it used to be that the run was called on a
timeout like window.setTimeout(run, 1);. Now this is only called for
isKHTML, and there is a direct call to run() otherwise. This for some reason
gave the recursion error for me. When I reverted this line and use the
timeout version, the recursion error disappeared. I am not sure about the
big picture of what's going on, but that gave me a dirty fix for now.

Same here. I am getting too much recursion in places I didn't have problem
earlier as well. Looking at the generated source, it is clear that the java
script gets included more than once, not just once in the header.

I'd love to see a menu bar for Wicket.

I've been researching the topic and I found these solutions

Re: [Wicket-user] ajax refresh on date picker

[Pierre-Yves Saumont]

I am afraid there is still a problem. I tested the fix in the quickstart 
I had made and it worked fine. However, in my application, selecting a 
date in the datepicker cause a Javascript error. FF reports this error as:

Erreur : too much recursion
Fichier source : 
http://localhost:8080/ceagrap/app/resources/wicket.extensions.markup.html.datepicker.DatePicker/calendar.js
Ligne : 1796

Date.prototype.__msh_oldSetFullYear = Date.prototype.setFullYear;
Date.prototype.setFullYear = function(y) {
   var d = new Date(this); <<< line 1796
   d.__msh_oldSetFullYear(y);
   if (d.getMonth() != this.getMonth())
 this.setDate(28);
   this.__msh_oldSetFullYear(y);
};

In IE6, the error message is "not enough stack space". The same line 
number is reported, but the next line is highlighted:

Date.prototype.__msh_oldSetFullYear = Date.prototype.setFullYear;
Date.prototype.setFullYear = function(y) {
   var d = new Date(this);
   d.__msh_oldSetFullYear(y); <<< line 1796
   if (d.getMonth() != this.getMonth())
 this.setDate(28);
   this.__msh_oldSetFullYear(y);
};

If I reload the page, the error disapears.

Re: [Wicket-user] question

[Patrick Angeles]

I realise  is very simple and meant just for convenience, but
it's awfully convenient.

Would it make sense to have the concept of a base package? For example:


   HomePage.html This is com.mycompany.web.HomePage 
   login/LoginPage.html This is com.mycompany.web.login.LoginPage 
   some/other/package/IndexPage.html This is
com.mycompany.web.some.other.package.IndexPage 


For that matter, I think a 'mount' method that traverses a base package
would be nice, for example:
WebApplication.mountAllSubPackagePages (String baseDir, PackageName
basePackage)

So a call to:
webApplication.mountAllSubPackagePages ("/base", PackageName.forClass
(com.mycompany.web.HomePage.class))

Would mount the following bookmarkable URLs:
contextname/app/base/HomePage
contextname/app/base/login/LoginPage
contextname/app/base/some/other/package/IndexPage

Re: [Wicket-user] progress indicator

[Pierre-Yves Saumont]

I use to experiment first and read only after. I remember few years ago 
(in the pre mp3 era) I needed sound streaming in an applet so I wrote a 
GSM decoder. Only when it was up and running, I searched the web and 
found it was already available in JavaSound. (But of course, mine was 
much better ;-) )

Re: [Wicket-user] progress indicator

[Korbinian Bachl]

well, my experience is: if you put anything online, someone will come and
try to skrew it up :/ 

because of that, I see anything client side just as a "gimmick" and regard
all data coming from it as potential dangerous... 

but helping users is also ok :P

Re: [Wicket-user] progress indicator

[Pierre-Yves Saumont]

Well, technically, you're right. However, I think we are speaking of 
different use cases. My use case is a fair user wanting to click on an 
link and not aware that he has to wait for the result. So he might click 
a second time if he's waiting too long. For this use case, we often see 
a message that says "Wait for the answer. Do not click twice or your 
order (or whatever) will be processed twice".

In that use case, I think "Ajax" can help. (By the way, it is client 
side processing. Nothing to do with Ajax).

Your use case is more an unfair user trying to screw the system. In that 
case, I will of course try to install protections on the system side, 
but I will not try to protect the user. ;-)

OK, So I did the upgrade manually, but it keeps throwing an exception when
it attempts to open a wicket editor.  I have rolled back to 0.3.0.  The

Re: [Wicket-user] progress indicator

[Nino Wael]

I do agree, but this is a usability question first of all. 

Secondly I agree that I might have the class that are generating the report 
wrapped as a thread and then having some ajax come ask if the thread is done 
until it is done and then generate the link to the temporary storing url, and 
showing it on the page. This would also allow a cancel button to be added

This way the user could be shown a revolving gif until a ajax call replaced it 
with the link.

Re: [Wicket-user] progress indicator

[Nino Wael]

Completely correct. 

As we generate a report when the user clicks the submit button, and while the 
page are loading we dont want the user to play around in the mean while. 

I've been thinking of combining some of the ajax stuff. Like having the ajax 
modal window plus the progress indicator. 

Basically when the user clicks the generate report button, a AJAX modal pops 
up(panel version) in the modal there are the ajaxlink with an progress 
indicator. So when the user clicks it or maybe on panel load? It Generates the 
report and url to the report so that the user can save it.


BTW if user disables JAVASCRIPT they will not be able to use the system, and 
gets a nice error page telling them to enable it or wait till they do:) I guess 
these days its pretty hard not having javascript in your web applications, well 
at least if customer wants them fancy and glittery.


Regards Nino

Re: [Wicket-user] progress indicator

[Korbinian Bachl]

it wouldnt work to prevent the user from doing sth. -  even if he has JS
enabled, he might abuse it... ajax has always be treatet as unsecure... and
the basic problem the thread started with, cant be solved by ajax, it has to
be solved by the server checking the current state of the process thats
going on...

[Wicket-user] Dependent detachable models

[Leszek Gawron]

Hello,
I have a question:

Suppose I have a detachable model which loads master instances (say 
leagues entities using hibernate)

add( new ListView( "leagues", new UserLeaguesModel( this.leagueService ) ) {
 @Override
 protected void populateItem( ListItem listitem ) {
 League league = (League) listitem.getModelObject();

 listitem.add( new Link( "leagueLink" ) {
 @Override
 public void onClick() {
 System.out.println( "link clicked" );
 }
 }.add( new Label( "leagueName", league.getName() ) ) );

 listitem.add( new ListView( "matches", new 
LeagueLastMatchesModel( leagueService, league, 10 ) ) {
 @Override
 protected void populateItem( ListItem newsItem ) {
 // populate match info here
 }
 } );
 }
} );

Both UserLeaguesModel and LeagueMastMatchesModel are the instances of 
LoadableDetachableModel. What bothers me here is the fact that I need to 
  create the dependent model with 'league' parameter (which might be 
large so I do not want to keep it attached).

I do not want to pass league.id only as my whole business layer is 
strongly typed and uses entities as parameters.

Questions:

  - does it change anything if I passed listItem.getModel() ?
  - if the former is also not a good idea how can I assure full 
detachability (means no League object gets serialized to session)?

Re: [Wicket-user] progress indicator

[Korbinian Bachl]

Hi,
 
i dont understand what you mean? - how can a disabled 
onSubmit button stop the user from changing selected values?? if you plan it 
ajax like, how can u be secure that the user has JS activated and doenst 
deactivate it or ignore parts of it (like you can do with certain browser 
plugins) ?
 
basically, a check on a user side (in the browser) is a 
toy, but not a check - you can help the user to fill out forms and tell him he 
shoud do this and that, but you cant force him nor be sure that the data hes 
sending is trustful in any way...
 
Regards

  Hi
   
  We have a form where we would like

  selected values and we would like to display a progress meter(it does not have 
  to show the actual progress just a gif like the AJAX examples). I have been thinking of the 
  AJAX examples but I guess that since we somehow would like to stall the 
  browser it’s not really a good solution, we would have to add all for 
  components again just disabled and then on the end of the ajax call add them 
  all again enabled?
   
  Whats your 2 centavos on 
  this?

Hi Nino,

You can use the IndicatingAjaxLink, but I do not use it because I had 
developped my own WaitingAjaxLink before I discovered this one ;-)

AFAIK, IndicatingAjaxLink add a progress indicator at the right of the 
corresponding control.

My WaitingAjaxLink as a script before that make a transparent div laying 
over the form visible so that the user can't click on anything. It also 
changes the pointer image to something showing that clicking is 
forbidden. (You migh use an animated gif for this). Of course, another 
script is run after link execution to make the div invisible and restore 
the pointer.

Probably not the best solution since I desgined it knowing really not 
much about wicket, but it does the job.

By the way, disabling everything during Ajax call is making those calls 
synchronous, which is a little strange with Ajax. (Shouldn't it then be 
called Sjax ;-) )

Re: [Wicket-user] Optional confirmation when cancelling/leaving a form

[Nino Wael]

The wicket phonebook has
an example on howto do this or at least something similar..

confirmation when cancelling/leaving a form



 

Hi,

 

I am trying to implement a mechanism where a
confirmation dialogue is raised if the user leaves a form either via the cancel
button, or selecting to navigate to another page. I only want this dialogue to
appear if the model has changed so that the user knows that they have changed
the data but not saved it. The dialogue will allow the user to select
‘yes’ to navigate to their next page or ‘no’ to stay on
the current page.

Has anyone implemented something similar or have an
idea how it can be done. 

 

The idea I have had is to intercept the onChange event
on all the controls changing the forms model. This would switch the buttons to
versions which contain a SimpleAttributeModifier which adds the _javascript_
confirm dialogue on the onClick event. This all seems very messy so any simpler
solutions would be gratefully received.  

 

Thanks in advance, 

 

Jeremy

Can I use CheckGroupSelector with CheckBox (instead
Check) ?
Because I want to be notified when a selection was
changed (CheckBox.onSelectionChanged)?

Thanks,
Decebal
