Re: [Wicket-user] i18n and SimpleFormComponentLabel

[Erik van Oosten]

Hi Rüdiger,

Although at the end of your e-mail I thought "yes, he's right!" there is 
one thing you missed: the label does not have to have the same text as 
the name of the field.

For example, in my current application I have the following components 
on a search form:
Component:label-housenumber  [field-from] [field-till]
Text/fieldname:House number[housenumber from] [housenumber till]

The label is coupled to the first field. As you can see the label is 
different from the name of the first field.
The only thing is, it is a bit weird I need to set a resource model on 
the field to get the text in the label.

Still, it would be nice to default to what you described. You could 
create an issue for it (with code to have it more quickly).
You can find Jira here: http://issues.apache.org/jira/browse/WICKET

Regards,
 Erik.

Re: [Wicket-user] i18n of booleans and enums

[Matej Knopp]

Actually I would do this using a custom converter. Then you don't have 
to decorate it.

You can have a
public class BooleanLabel {
...
IConverter getConverter() {
return new IConverter() {
...
}
}
}

In your converter decide how to display the value.
I don't think there is anything wrong with your model, just that the 
custom components like this are IMHO easier to use.

Re: [Wicket-user] ListChoice changes appearance from dropdown to listbox

[TH Lim]

I came to the same conclusion as Nino. What I have observed was this,

1. For,

ListChoice selection = new ListChoice("disciplineSelection", new Model(),
disciplines)

, a list box is created in the web page.

2. For, 

ListChoice selection = new ListChoice("disciplineSelection", disciplines)

, a dropdown box is created in the web page.

3. For, 

ListChoice selection = new ListChoice("disciplineSelection",
disciplines);selection.setMaxRow(8);

,  a list box is created in the web page.

I find it strange because I used ListChoice instead of DropDownChoice but
yet it shows a dropdown box instead of a list box for case no. 2. Is it a
bug or am I missing something? Btw, there are 2 items in my discipline list.
Thanks

[Wicket-user] Wicket Shared

[Renan Camponez]

I am trying to use the same page instance for different tabs in a Panel, so
I can make an ajax request in one to update the fields of the other
Is there any "wicket-way" to do this?

[Wicket-user] leprosy professionalism

[Crow Ottilia]

I still think the size of the team needs to be as small as possible, even to 
the point of emaciation.
This RSS file is offered to individuals and non-commercial organizations only.
Or, if this isn't what Mark was getting at, then it does at least clarify my 
own thoughts on the matter. But I also didn't agree with him.
But the example does give a clear starting point.
Obviously using simple triangulation, etc. These are the bits that produces the 
magic slightly transparent background.
But I also didn't agree with him.
Mark's example focuses a lot on interface generalization but there's much more 
to REST, and the web, than this.
Prentice Hall Publishing sent me a copy of a book I did a technical review for 
some time ago. I can agree with Mark that REST does a great deal more to 
separate concerns compared to SOAP and WSDL but I'd say this goes far beyond 
fuzzy notions of generic interfaces. They said it had gone missing. It's a good 
read but it's also a bit confusing. Once such a precipitous cliff is identified 
it can be carefully avoided it and all is well again.
I have a hard time imaging any way to effectively manage a group of people that 
size working on a single project in any industry.
This article explains how to achieve this functionality.
I still think the size of the team needs to be as small as possible, even to 
the point of emaciation.
This assumption is also the source of the nausea. I understood just what Mark 
he was saying but the words didn't really compute.
This assumption is also the source of the nausea. Both will probably survive.
Thrid and the point of this post is can the old BBS days trick of Wardialing to 
find connections help in a war? Big Bang projects always seem to attract huge 
budgets and massive headcount, but there are few companies out there who could 
even field such a large workforce and invest so many billions. Both will 
probably survive.
This fixes things up.
This RSS file is offered to individuals and non-commercial organizations only.
This erroneous assumption leads to the broken example and his strange notion of 
generalization.
Which operations invalidate which resources; which PUTs are idempotent, etc. 
"They were moving slowly over the houses," she said.
This assumption is also the source of the nausea. But say this out loud and 
there's a definitely an uncanniness that hangs in the air. So, programming 
language is not a set of features, it is a set of restrictions".
This assumption is also the source of the nausea. But the example does give a 
clear starting point. He talks about how he is pleased with Sun's decision and 
how they're implementing it and how he thinks that Kaffe, GCJ, etc will 
continue to thrive. The important question is whether REST does separate 
concerns and, if so, precisely how it achieves such separation.
But the example does give a clear starting point. It's been explored by many 
people in many places at many times. But after the feeling of vertigo induced 
by Mark's essay it occured to me that perhaps there's still something here.

[Wicket-user] i18n of booleans and enums

[Logi Ragnarsson]

Hello everyone,

I'm relatively new to wicket, but I'm building a web application where several 
forms are backed by compound models with boolean and enum constituent models. 
The straight-forward implementation of this would display true/false values, 
and the names of the enum values in the code, which is generally not very 
user friendly (peopel say "yes" and "no" and they don't generally put choices 
in all upper case) and not internationalized, so Something Must Be Done.

I'd like to show my solution, with input from Igor Vaynberg, for comment and 
perhaps re-use. I've only got the boolean case implemented, but the enum case 
is basically more of the same with more localization resources needing to be 
loaded.

The simplest case (and one not worth all this effort) is when displaying a 
boolean value in a ListView:
  new Label("active");
which becomes:
  new Label("active", new I18nBooleanModelDecorator(item.getModel()));
where the (attached) I18nBooleanModelDecorator has been applied to the model. 
This will display "yes" or "no" for the boolean values unless those strings 
have been replaced by setting the I18nBooleanModelDecorator.TRUE and 
I18nBooleanModelDecorator.FALSE licalization strings to something else.

Usually on a form you'd use a check-box for setting boolean values, such as 
this:
  new CheckBox("active");
but for illustrative purposes suppose we have this text field instead:
  new TextField("active");
The following will work if the component's compound model has been set before 
the form is populated with fields and will not be changed later:
  new TextField("active", new I18nBooleanModelDecorator(getModel()));
but in reality getModel() is likely to return null or to return a model which 
is later replaced with another in response to user or application events, so 
the text field would now either have no underlying model or an out-dated one.

For this I wrote a ComponentModelDelegator which takes a Component and 
delegates all model operations to the current model of that component like 
so:
  IModel model = new ComponentModelDelegator(this)
  new TextField("active", new I18nBooleanModelDecorator(model));

This works like a charm and you can write "nei" in my Icelandic locale to set 
the value of the active property of my underlying model to false... before 
you then change the code back to using the much more reasonable CheckBox 
class.

Is there anything terribly wrong with this? Would this be useful for other 
wicket users, probably in combination with the similar decorator for 
enumerations?

[Wicket-user] i18n and SimpleFormComponentLabel

[Rüdiger Schulz]

Hello everybody,

I just wanted to dive a little into wicket i18n, and stumbled upon this:

Say I have page with this simple form:

Form form = new Form("form");
add(form);

FeedbackPanel feedback = new FeedbackPanel("feedback");
form.add(feedback);

TextField tx = new TextField("text");
tx.setRequired(true);
form.add(tx);

and corresponding properties file for the page:

form.text=FormTexti18n

When I submit the empty form, I get the message:

field 'FormTexti18n' is required.

So, my label from the properties is used for the validation message. So
far, so good.

Now I'd like to have a label for the TextField, displaying the same
string from the properties. Also, a normal Label is not enough for me,
I'd like to change its CSS style depending on having an error.

So I start with this:

SimpleFormComponentLabel label =
new SimpleFormComponentLabel("textLabel", tx);
form.add(label);

Now I get an error:

java.lang.IllegalStateException: Provided form component does not have a
label set. Use FormComponent.setLabel(IModel) to set the model that will
feed this label
 at
wicket.markup.html.form.SimpleFormComponentLabel.(SimpleFormComponentLabel.java:46)

Okay, this error tells me what to do, and I could do a

tx.setLabel(new ResourceModel("form.textLabel"));

And everything works fine. But ... :-)

Is this really necessary? This ResourceModel is only required for the
SimpleFormComponentLabel, I already have label through the properties!

The JavaDoc FormComponent#getModel() says

"The value will be made available to the validator property by means of
${label}."

Which it does, but I'm wondering why SimpleFormComponentLabel can't do
this the same way as the validator? Or is this one of those issues which
will be gone with the changes in 2.0?

greetings,


Rüdiger

Re: [Wicket-user] updating page contents before and after long process

[Eelco Hillenius]

You could do the processing in a separate thread, and return the page
immediately with the progress component that polls (e.g. using Ajax,
though doesn't have to) for the progress. Or like Igor said, put your
progress bar on the page to begin with, make your form submit an ajax
submit, on the submit start that other thread and make the progress
component visible (and it will thus automatically start polling).

Re: [Wicket-user] SortableDataProvider, size() & iterator(int first, int count), Correct execution order?

[Igor Vaynberg]

no its not possible there is logic that ties the return call of size() to a
few things that need to happen before the call to iterator()

all it takes is your own subclass that i have shown you, i dont think its a
big deal.

Re: [Wicket-user] updating page contents before and after long process

[Jaime De La Jara]

Thanks, though I'm not sure if this is what I need, maybe I didn't explained my 
problem clearly. First, some code may help :

The html :
..
..


  
var bar1= 
createBar(300,15,'white',1,'#215dc6','#428eff',85,17,3,"");

 
.
 . OK SubmitLink

Java :

... Page constructor
 
 final WebMarkupContainer bar = new WebMarkupContainer("progressBar");
 final Label msg = new Label("msg", "Processing Vendors Load");
 bar.add(msg);
 add(bar.setVisible(false));
...
add(new SubmitLink("okLink")
{
  public void onSubmit()
  {
// Here I should make the progressBar visible and it should be displayed
 bar.setVisible(true);  (*)
 // This is the process that takes some time (~ 15 sec)
 getVendorDao().loadVendors(); (*)
// Here I should display a message informing the load results
// Here I should make the bar invisible again.
 bar.setVisible(false);
  }
}
.

The problem is, that the page is not reloaded until (*) is completed so the bar
is not made visible before the loading process begins. 
Any hints are greatly appreciated, 

Jaime.

[Wicket-user] Show a disabled ImageButton

[NickCanada]

I have an ImageButton used to submit a form. I extended the
RenderedDynamicImageResource class so that I have a transparent background
but now I want to show the button in a disabled state. 
It seems when the FormComponent class launches onDisabled(ComponentTag tag)
my ImageButton is not drawn at all.

Is there a way of rendering an alternative dynamic image resource that would
allow me to render a disabled button look? (The Button class does this by
default)


Any help appreciated.
Thanks 

Nick

Re: [Wicket-user] Sortable Headers - Default sort

[Igor Vaynberg]

SortableListViewHeaderGroup has a protected setSortedColumn so if you
subclass it and create a public method that calls this one you should be
good to go

something to keep in mind is that that particular example was created before
the repeaters package, so i think it is pretty much deprecated. see
repeaters/datatable example for something that works nicer.

Hi

I am using the classes SortableListViewHeader, SortableListViewHeaders and
SortableListViewHeaderGroup for doing my sorting in my webapplication.

But the sorting only works, when I click on the header of my table.
Is there a way to set the sorting without clicking on the header of my
table?

The background is, that I want to remember what column was sorted last and
when the user goes back to the overview page, the sorting should be the same
as when he left the page.

Thanks for any help

[Wicket-user] Wicket Stuff SVN repository change

[Martijn Dashorst]

Sourceforge has changed the connection policy. If you work on a Wicket
Stuff project, please follow these instructions:

= taken from [1] =
Users new to the SourceForge.net Subversion Service should skip this
section, it only covers changes that affect users who have been using
Subversion prior to the switchover date

On November 31, 2006 the access method for Subversion changed. This
document reflects those changes. The old method had numerous problems,
including spurious 50x error messages and other issues that kept it
from functioning fully. This newly documented access method solves
many, if not all of the issues with the old mechanism.

Users of the old method
(https://svn.sourceforge.net/svnroot/PROJECTNAME) should switch to the
new access method
(https://PROJECTNAME.svn.sourceforge.net/svnroot/PROJECTNAME) using
these steps:

Make a copy of your local working copy.
Run 'svn info' at the root of the repository content, it should
display a line that appears similar to: URL:
https://svn.sourceforge.net/svnroot/PROJECTNAME/trunk
Run the following command at the root of the working copy: svn switch
--relocate https://svn.sourceforge.net/svnroot/PROJECTNAME/trunk
https://PROJECTNAME.svn.sourceforge.net/svnroot/PROJECTNAME/trunk

at wicket.util.concurrent.CopyOnWriteArrayList.size (
CopyOnWriteArrayList.java:152)
at wicket.feedback.FeedbackMessages.messages(FeedbackMessages.java:258)
at wicket.feedback.FeedbackMessagesModel.onGetObject(
FeedbackMessagesModel.java:101)
at wicket.model.AbstractDetachableModel.getObject (
AbstractDetachableModel.java:104)
at wicket.Component.getModelObject(Component.java:990)
at wicket.markup.html.panel.FeedbackPanel.updateFeedback(FeedbackPanel.java
:234)
at wicket.Page$2.component (Page.java:372)
at wicket.MarkupContainer.visitChildren(MarkupContainer.java:744)
at wicket.Page.renderPage(Page.java:368)

.

by default feedbackMessages utilize
wicket.util.concurrent.CopyOnWriteArrayList . But it internally use an
transient Object[] array_ without checking null and lazy initialization.

anyway, I may try simpler wicket  application for evaluating terracotta...
It's hard to figure out what's going on for deep objects graph.

[Wicket-user] Sortable Headers - Default sort

[Robert Thullner]

Hi

I am using the classes SortableListViewHeader, SortableListViewHeaders and 
SortableListViewHeaderGroup for doing my sorting in my webapplication.

But the sorting only works, when I click on the header of my table.
Is there a way to set the sorting without clicking on the header of my table?

The background is, that I want to remember what column was sorted last and when 
the user goes back to the overview page, the sorting should be the same as when 
he left the page.

Thanks for any help
Robert

[Wicket-user] Lazy mans fix for a cancel button

[Nino Wael]

Hey



Sometime ago we discussed that I needed a cancel button. The need was there 
because of a certain page had long loading times, not because of wicket though. 
We talked about a worker thread so I could start the report generation and then 
the wicket page could come and ask the worker thread once in a while if it were 
done, if the user in the mean time had pressed cancel we could just cancel the 
worker thread. While pretty easy to describe in theory it does require some 
effort to create and theres a lot of stuff to take in consideration(could we 
really stop the report generation and if we forced a stop what would our 
backend server say? ++ more).



As by default im pretty lazy. So I'll call this the lazy mans fix for a cancel 
button.



So since wicket has a singular model for page requests processing per session 
this requires that we go out side of wicket, to a pretty simple jsp page that 
invalidates the session and then returns the user to what ever page the user 
came from (or as close as it can be if it's a wizard, with some effort you 
could get the user back to the correct page).



So to recap:



1.  Wicket Page that has cancel button forwards to an JSP page
2.  JSP page invalidates session and forwards back to wicket page
3.  Wicket interprets the user as being a new user(since the other users 
session are invalidated) and processes request as normal.



Do note that the original page(the page that the user pressed cancel on) will 
still have to be processed, since the page thread aren't cancelled.





Regards Nino

Re: [Wicket-user] Terracotta open source and tested with wicket-examples

[Ingram Chen]

hhmm as Wicket always check serializable, I think my app's session does
not refererence to non-serializable WebApplication. but  the stack trace
shows:


com.tc.object.ClientObjectManagerImpl.lookupOrCreate(ClientObjectManagerImpl.java:306)

com.tc.object.tx.ClientTransactionManagerImpl.fieldChanged(ClientTransactionManagerImpl.java:507)
com.tc.object.TCObjectImpl.objectFieldChanged(TCObjectImpl.java:272)
wicket.Session.__tc_setsessionStore(Session.java)
wicket.Session.getSessionStore(Session.java:900)
wicket.Session.getAttributeNames(Session.java:881)
wicket.Session.visitPageMaps(Session.java:753)
wicket.Session.init(Session.java:581)
wicket.RequestCycle.prepare(RequestCycle.java:911)
wicket.RequestCycle.step(RequestCycle.java:986)
wicket.RequestCycle.steps(RequestCycle.java:1084)
wicket.RequestCycle.request(RequestCycle.java:454)
wicket.protocol.http.WicketServlet.doGet(WicketServlet.java:219)
javax.servlet.http.HttpServlet.service(HttpServlet.java:689)

I use Wicket 1.2.3 so Session.java:900 is

public class Session {

   protected ISessionStore getSessionStore()
   {
   if (sessionStore == null)
   {
   sessionStore = getApplication().getSessionStore();  // line no
900
   }
   return sessionStore;
   }
}

it looks like terracotta intercept assignment "sessionStore = " and add a
setter

wicket.Session.__tc_setsessionStore(Session.java)

but sessionStore referenced by Application

Re: [Wicket-user] Terracotta open source and tested with wicket-examples

[Eelco Hillenius]

Why would you put a reference to the application in your session
anyway? You can get the current app like Application.get(). Otherwise,
you can make the field transient, though when it gets deserialized,
you'd have to set the field yourself somehow.
