I've created a FormComponentPanel that wraps three text fields, to mimic 
a phone number.  I created a custom validator, which I have added to the 
panel.  When I submit the form, the validator does not seem to be fired. 
 If I attach the validator to another form component, it fires without 
a problem, which leads me to believe that the FormComponentPanel has 
problems with it.  Is there some trick, or is this a bug?

Re: FormComponentPanel and Validators

did you properly override convertintput() on the formcomponentpanel to
generate an object based on the 3 children? by default it returns null and
validators do not run on null values...

Re: Page.detachModels() not working like it used to

2007-10-04 Thread Dan Syrstad

Actually, Page.detach() is not callable from a JUnit test that uses
WicketTester in 1.3.0beta3. It throws an exception:

org.apache.wicket.WicketRuntimeException: No RequestCycle is currently set!
at org.apache.wicket.Component.getRequest(Component.java:1443)
at org.apache.wicket.Page.onDetach(Page.java:1406)
at org.apache.wicket.markup.html.WebPage.onDetach(WebPage.java:360)
at org.apache.wicket.Component.detach(Component.java:899)


In 1.2.6, you could call Page.detachModels() and the test would run fine.

-Dan

Here's my test:

-
import junit.framework.TestCase;
/*
//1.2.6
import wicket.Component;
import wicket.Page;
import wicket.model.LoadableDetachableModel;
import wicket.util.tester.WicketTester;
*/

//1.3
import org.apache.wicket.Component;
import org.apache.wicket.Page;
import org.apache.wicket.model.LoadableDetachableModel;
import org.apache.wicket.util.tester.WicketTester;

public class WicketDetachTest extends TestCase {
public WicketDetachTest() { }

public void testDetach(){
WicketTester tester = new WicketTester();
Page page = tester.startPage(Wicket12Page.class);

tester.debugComponentTrees();

Component c = tester.getComponentFromLastRenderedPage
(listView:0:labelWithDetachableModel);
LoadableDetachableModel childModel =
(LoadableDetachableModel)c.getModel();

// Child currently attached due to rendering
assertTrue(childModel.isAttached()); // Attached

// Detach children
//page.detachModels();  // 1.2.6 - Does not detach child models in
1.3
page.detach(); // 1.3  FAILS - not in request cycle

assertFalse(childModel.isAttached()); // Not attached

// Cause attachment
c.getModelObject();
assertTrue(childModel.isAttached()); // Attached
}
}

  The thing is that  In beta3, Page now just acts like a Component as far
 as
  detachModels() is concerned and Component.detachModels()/detach() does
  notdetach all of the child models.
  Component.detach(), in fact, calls detachChildren() which is an empty
  method.
 

 detachChildren() is overriden by MarkupContainer which does detach its
 children
 (see below). So there must be something wrong with your unit test.

 void detachChildren()
 {
 // Loop through child components
 final Iterator iter = iterator();
 while (iter.hasNext())
 {
 // Get next child
 final Component child = (Component)iter.next();

 // Call end request on the child
 child.detach();
 }
 super.detachChildren();

Re: RequestCycle?

2007-10-04 Thread Sam Hough


I think it is setup with ThreadLocal so you can get it easily with
RequestCycle.get(). You can also provide your own version from
Application.newRequestCycle which might be more what you need to hook in
start/end events.

Re: FormComponentPanel and Validators


I take it back.  It is the validator itself that isn't functioning as expected. 
 In my panel, I did not override convertInput(), as expected.  The JavaDoc 
suggests that I call setConvertedInput() from within convertInput(), except 
that setConvertedInput() does not exist.  Has this been replaced with 
setModelValue(), and just not reflected in the JavaDoc?

DateTimeField problem

2007-10-04 Thread giladgaron


Hi,

I'm new to wicket, and I will appreciate if could help me!


I'm having problems using DateTimeField, i'm getting the following
exception:

WicketMessage: Unknown tag name with Wicket namespace: 'panel'. Might be
you haven't installed the appropriate resolver?

I've tried to google it, but no luck... I also tried looking for some docs
on the Wicket-Datetime, but no luck...
I'm sorry if this is a newbie question... :)

Source Code:

Adding a label when I add a FormComponent.

2007-10-04 Thread Clay Lehman

Hey Everyone,

 

I want to create a subclass of a Form Component (Let's use TextField for
this example) which takes a String in the constructor, and automatically
adds the HTML for a Label before the field.  I want to provide all the
default functionality of a TextField (like adding behaviors, and
validators), so I don't think a Panel will work for me.

 

 

I found a post where it mentioned (as a hack)to override onRender to add
HTML for the label directly, but this runs into problems when you
include the Component in an AJAX page (whenever you re-add the
component, it calls onRender, and you add the HTML for the label
multiple times.

 

Is there a way to do this using SimpleFormComponentLabel, or some other
construct?

 

Could I use  FormComponentPanel? Or is there some configuration and
functionality in AbstractTextCompnent and TextField which I would lose
by using a FormComponentPanel?

 

Thanks for any advice!!

Re: Graceful handling of ajax after session expiration

2007-10-04 Thread leok

I looked into this a bit more, and it looks like
WebRequestCycleProcessor.resolve(RequestCycle, RequestParameters) always
checks to see if an Ajax request is being made before a Page gets to be
instantiated and stored in the session. If the Page doesn't exist in the
PageMap, the request simply redirects to the Session Expired page. It seems
like the Page could be created if its information were encoded in the Ajax
request.

Is there a reason why an AjaxLink couldn't encode a stateless URL a la
BookmarkablePageRequestTargetUrlCodingStrategy s.t. the Ajax'ed component
and its containing page could be created if the page didn't exist in the
PageMap?

leok wrote:

Thanks for the response! I'm not sure if this solves my problem though, or
if I understand this correctly. Even if I use HybridUrlCodingStrategy to
mount the page, I will still get redirected to a Session Expired page if
I try to use any ajax-enabled component.

A second problem emerges when I get redirected to the Session Expired
page, hit the back button, and attempt to invoke the ajax-enabled
component again. This time Wicket thinks I'm sending the ajax request to
the Session Expired page and redirects me to a plain old error page with a
stack trace.

It'd be nice to be able to register Wicket ajax components in some state
that persists beyond a single user's session.

Martijn Dashorst wrote:

1.3 has a new URL encoding strategy that would make this somehow
possible: iirc it is the hybrid url coding strategy, and is for
instance used at http://thoof.com

The url becomes bookmarkable, and has the page nr and version number
encoded in the url, but wicket will use the bookmarkable part when
there is not session.

Hi there - I'm trying to add some graceful handling of ajax behavior

Ideally, Ajax calls would continue to function after session expiration.
I've scanned the list regarding this issue, and I think it makes sense
for
certain types of ajax requests, e.g. ajax requests that resemble

form interaction. Is there a way to hack this sort of behavior with
Wicket?

Null values in Lists question

2007-10-04 Thread Doug Leeper


I am sure there is a more elegant way than what I am doing so I thought I
would throw out the following question.

I have a List that displays a date in one of its columns.  If that date is
null, nothing is displayed...fine and dandy.  However, when applying a style
to the table, aka border to that cell, nothing will show up because the td
element has nothing in it.

Currently I am placing nbsp; before and after  tags to ensure that the td
element has something in it.

Is there a more elegant way to do this, i.e. Wicket way?

Thanks

Re: Threading wicket

 how can I force from a middle of the loop, which may run up to few
 minutes to update a component's value?
 I am manipulating a lot of files and I would like to let the user know
 how much of the processing is already done.
 I would like to start processing the files when user reaches certain
 page and on this same page I want to display statistics of the process.
 As an example I tried to use a Clock from your ajax example, but I
 cannot manage it to update during running of the loop. I thought of
 achieving it somehow with threads, is this right direction?
 What is the correct way to do it?

Check out 
org.apache.wicket.extensions.ajax.markup.html.form.upload.UploadProgressBar.
It's not exactly what you want, but it should give you some ideas.

Cool, thanks Martijn, learned something useful today!

(which is a pleasant escape from my philosophy homework where I have to 
try understand what stuff like It follows that trying to give tensed 
thoughts or sentences non-token-reflexive truth-conditions, tensed or 
tenseless, always leads to contradiction means...) :-))

I am sure there is a more elegant way than what I am doing so I thought I
would throw out the following question.

I have a List that displays a date in one of its columns.  If that date is
null, nothing is displayed...fine and dandy.  However, when applying a style
to the table, aka border to that cell, nothing will show up because the td
element has nothing in it.

Currently I am placing before and after  tags to ensure that the td
element has something in it.

Is there a more elegant way to do this, i.e. Wicket way?

Thanks

In your application class:

@Override
public RequestCycle newRequestCycle(Request request, Response response)
{
return new WebRequestCycle(this, (WebRequest)request, response)
{
@Override
protected void onBeginRequest()
{
// open session
}

@Override

};
}

If you use Spring for instance, you could just configure the hibernate

Going back after save or cancel method?

I have a classic list and edit page setup. You select an object that you 
then pass to the edit page. My hang up is how to I return the user to 
the list page, if the list page took a constructor parameter so it knows 
what to list? In other words the list page has a constructor parameter, 
so how can I just send the user back to the list page in it last state?

More on Wicket/Hibernate...

2007-10-04 Thread Neil B. Cohen

I suspect I'm biting off more than I can chew conveniently but maybe 
someone can push me in the right direction...


I'm attempting to build a fairly simple web application with Wicket, and 
I'd like to use Hibernate to manage the database access (although other 
frameworks like Cayenne have been suggested and I'll look at them too...)


I think I've figured out the basic application structure, and how to map 
my data to an html page. But I don't think I understand the 
relationships between web sessions, hibernate sessions, DAO objects etc. 
I need to open a mysql db, read a set of objects from a table, and 
display them in a (paged) table on the screen. I've looked at several 
examples but they are using in-memory databases, or Spring along with 
Hibernate and I can't get a handle on what needs to be done to whom and 
by whom


Anyone have a really simple MySQL example like that? Or an online 
tutorial that I could follow?

Re: More on Wicket/Hibernate...

It's really very simple. I'm doing the same thing here. You simple use 
the HibernateUtil example that is in the Hibernate documentation. Then 
you simple create a custom RequestCycle by overriding this method in 
your application. With the request cycle you can open and close 
Hibernate seesion. Then with a custom RequestCycle you can get it from 
anywhere, it uses thread local, and us it to access your database. 
Here's some example code:

##
   @Override
   public RequestCycle newRequestCycle(Request request, Response 
response) {

   return new RequestCycleImpl(this, request, response);
   }
##
public class RequestCycleImpl extends WebRequestCycle {

   private Session hibernateSession;

   public RequestCycleImpl(Application application, Request request, 
Response response) {

   super(application, (WebRequest) request, response);
   }

   @Override
   protected void onBeginRequest() {
   this.hibernateSession = 
HibernateUtil.getSessionFactory().openSession();

   }

   @Override
   protected void onEndRequest() {
   if (this.hibernateSession != null) {
   this.hibernateSession.close();
   }
   }

   public Session getHibernateSession() {
   return hibernateSession;
   }
}
##
public class AllDivisionModel extends LoadableDetachableModel {

   protected Object load() {
   Session session = ((RequestCycleImpl) 
RequestCycle.get()).getHibernateSession();

   Transaction tx = session.beginTransaction();
   try {
   @SuppressWarnings(value = unchecked)
   ListDivision results = (ListDivision) 
session.createCriteria(Division.class)

   .addOrder(Order.asc(name))
   .list();
   tx.commit();
   return results;
   } catch (Exception e) {
   Logger.getLogger(getClass()).error(e);
   tx.rollback();
   }
   return new ArrayList();
   }
}
##
   private boolean isLoggedIn(String username, String password) {
   Session session = ((RequestCycleImpl) 
getRequestCycle()).getHibernateSession();

   Transaction tx = session.beginTransaction();
   try {
   SysUser user = (SysUser) 
session.createCriteria(SysUser.class)

   .add(Restrictions.eq(username, username))
   .add(Restrictions.eq(password, password))
   .uniqueResult();
   if (!user.isLockout()) {
   return true;
   }
   tx.commit();
   } catch (Exception e) {
   Logger.getLogger(getClass()).error(e);
   tx.rollback();
   }
   return false;
   }
##

All that said, I'm pretty new my self, so I'm sure it can be improved. 
This seems to work so far for me.

RE: Adding a label when I add a FormComponent.

2007-10-04 Thread Clay Lehman

I implemented a simple IComponentBorder, and anything I put in the
beforeRender gets added again every time I try to update the component
with AJAX.

My IcomponentBorder has: 
public void renderBefore(Component component)
{
Response resp = component.getResponse();
resp.write(Label);
}

To update the input box using AJAX I have a behavior:

Input1.add(new AjaxFormComponentUpdatingBehavior(onchange)
{
protected void onUpdate(AjaxRequestTarget target)
{
theItem.name=new value;
target.addComponent(input2)
 }
});

When I do target.addComponent(input2), the renderBefore adds Label
again, so the HTML looks like:

Label Label input wicket:id=input2/

Am I using IComponentBorder wrong?

Thanks for any help!

 Hey Everyone,



 I want to create a subclass of a Form Component (Let's use TextField
for
 this example) which takes a String in the constructor, and
automatically
 adds the HTML for a Label before the field.  I want to provide all the
 default functionality of a TextField (like adding behaviors, and
 validators), so I don't think a Panel will work for me.





 I found a post where it mentioned (as a hack)to override onRender to
add
 HTML for the label directly, but this runs into problems when you
 include the Component in an AJAX page (whenever you re-add the
 component, it calls onRender, and you add the HTML for the label
 multiple times.



 Is there a way to do this using SimpleFormComponentLabel, or some
other
 construct?



 Could I use  FormComponentPanel? Or is there some configuration and
 functionality in AbstractTextCompnent and TextField which I would lose
 by using a FormComponentPanel?



 Thanks for any advice!!

 with AJAX.

 My IcomponentBorder has:
 public void renderBefore(Component component)
 {
 Response resp = component.getResponse();
 resp.write(Label);
 }

 To update the input box using AJAX I have a behavior:

 Input1.add(new AjaxFormComponentUpdatingBehavior(onchange)
 {
 protected void onUpdate(AjaxRequestTarget target)
 {
 theItem.name=new value;
 target.addComponent(input2)
  }
 });

 When I do target.addComponent(input2), the renderBefore adds Label
 again, so the HTML looks like:

 Label Label input wicket:id=input2/

 Am I using IComponentBorder wrong?

 Thanks for any help!

Can we chain WebRequestCodingStrategies (CryptedUrlWebRequestCodingStrategy and an SSL coding strategy)

2007-10-04 Thread Chris Lintz


Hi,
Can we chain WebRequestCodingStrategies?  I want to use the
CryptedUrlWebRequestCodingStrategy and an SSL coding strategy as seen on
http://cwiki.apache.org/WICKET/how-to-switch-to-ssl-mode.html#HowtoswitchtoSSLmode-CreateNewResponseStrategy

Is this possible to use multiple WebRequestCodingStrategy objects?

Re: Adding a label when I add a FormComponent.

2007-10-04 Thread ChuckDeal


If you are going to have to add extra containers anyway, you could try it the
way we do it on my project.

In the html, we add both a label and input element with wicket ids.  to keep
it simple, the label's id is the same as the related component's id with
label appended to it.

Then, we have a createLabel method that takes the Component and it
automatically adds the label with the proper id.

TextField message = new TextField(message);
message.setLabel(new Model(Message));
add(message);
createFieldLabel(this, message);


protected FormComponentLabel createFieldLabel(final MarkupContainer
container, final FormComponent formComponent) {
FormComponentLabel label = new FieldLabel(formComponent.getId() + 
Label,
formComponent); 
container.add(label);
return label;
}

I don't know that 1.1 has a tar.  My project uses maven, so it was a snap to
add the Databinder bits to our pom.

Here is the page that gives the databinder snapshot repo info:
http://databinder.net/site/show/faq#updates

If you don't use maven, I could always send a 1.1-SNAPSHOT directly to
you...

FYI, The databinder site has some examples that help with learning how to
use and adapt the code to your own project.

 Yeah, I think Wicket is very suitable for what you want to do.
 
 So, I need a heavy component oriented framework, and Wicket seems to be
 suitable.
 But, for what I understood, Wicked is driven by pages. I would instead
 drive
 the presentation by some action (i.e.
 www.mycms.com/view/MyEntity/id/123),
 look into information system, find the suitable html page and then render
 it.
 
 You can implement that just the same. Replace your idea of actions by
 pages, and use a custom URL mapping to achieve that. There's multiple
 ways to do it.
 
 Learn how bookmarkable pages (would be your actions) work, and how to
 dynamically construct Wicket pages (investigate panels).
 
 Eelco
 
 

Thanks for your reply, that's what I think after reading better this forum.

And thanks to you all for remembering me that ever exists a better way to do

OOP passion and my Web programming needs.
Hope I can follow this way like I would.

  To update the input box using AJAX I have a behavior:

  target.addComponent(input2)

  When I do target.addComponent(input2), the renderBefore adds Label
  again, so the HTML looks like:
 
  Label Label input wicket:id=input2/
 
  Am I using IComponentBorder wrong?
 
  Thanks for any help!

   Hey Everyone,
  
  
  
   I want to create a subclass of a Form Component (Let's use TextField
  for
   this example) which takes a String in the constructor, and
  automatically
   adds the HTML for a Label before the field.  I want to provide all
 the
   default functionality of a TextField (like adding behaviors, and
   validators), so I don't think a Panel will work for me.
  
  
  
  
  
   I found a post where it mentioned (as a hack)to override onRender to
  add
   HTML for the label directly, but this runs into problems when you
   include the Component in an AJAX page (whenever you re-add the
   component, it calls onRender, and you add the HTML for the label
   multiple times.
  
  
  
   Is there a way to do this using SimpleFormComponentLabel, or some
  other
   construct?
  
  
  
   Could I use  FormComponentPanel? Or is there some configuration and
   functionality in AbstractTextCompnent and TextField which I would
 lose
   by using a FormComponentPanel?
  
  
  
   Thanks for any advice!!

Re: Adding to response header (filename)?


This works:

getWebRequestCycle().getWebResponse().setContentType(text/csv);
   
getWebRequestCycle().getWebResponse().setHeader(Content-Disposition, 
attachment;filename=\export_ + 
formatFile.format(Calendar.getInstance().getTime()) + .csv\);
   OutputStream cout = 
getWebRequestCycle().getWebResponse().getOutputStream();

   cout.write(out.toString().getBytes());
   cout.flush();
   cout.close();

But I get this in the logs. How can I do this better?

16:31:45,391 ERROR WebResponse:190 - Unable to redirect to:

How to NOT cause a hot redeploy with Jetty when HTML files change

2007-10-04 Thread Jason Mihalick

I have been successfully developing a Wicket application with Eclipse, Maven,
and the Maven Jetty plugin with hot redeploy enabled. However, I don't want
Jetty to do a hot redeploy of the application when I make a change to my
HTML files. I assume that Wicket will pick up these changes automatically
when running in Development mode, so there should be no need to reload the
whole app.

I have both Eclipse and Maven compiling classes to the same directory
(target/classes) so that when I make a change to a class in eclipse, Jetty
picks up the change and does a hot redeploy. This is a good thing. Since my
HTML files are located along side my classes, my HTML files are also
automatically copied by eclipse into my target/classes dir structure. This
should be a good thing too, but read on...

The problem is that whenever an HTML file changes and eclipse copies it to
my target/classes dir, jetty picks this up and reploys the application.
I've tried adding a ScanTargetPatterns section to my jetty plugin
configuration, but it doesn't work. Here is what I added:

scanTargetPatterns
scanTargetPattern
directorytarget/classes/directory
excludes
exclude**/*.html/exclude
/excludes
/scanTargetPattern
/scanTargetPatterns

Has anyone else got this to work, and if so, how? Your help is much
appreciated.

Re: webpage instance scope?

 I think I understand your explanations yet I struggle to see how scenario I
 was describing is optimization-only. Consider these scenarios:

 Shopping w/o signing in.
 1.I go to amazon.com and fill my shopping cart with stuff without signing
 in.
 2.I navigate away to somewhere else and short time later ( HttpSession
 timeout) type in 'amazon.com' to go back. At this point I'd still expect to
 see my cart's content.

 My Home Page is a portal
 1. My home page is my.yahoo.com. When I launch my browser I get
 authenticated via a previously-stored cookie.
 2.During the course of the same browser session I can navigate away to
 another site and then hit CTRL+H to go to my home page again.
 3.As I land on my.yahoo.com seems that I am *not* re-authenticated from a
 persistent cookie - instead a cookie issued in #1 is used to locate my
 server-side state.

 In both of these scenarios NOT retrieving state from steps #1 is not merely
 a non-optimization - but
 unexpected behavior. Do you agree?

No I don't. This is where bookmarkable pages are meant for. In both
cases you would use cookies, and these bookmarkable pages read the
cookies to determine what's in the cart.

Re: Wicket Meetup Amsterdam: a proposal

2007-10-04 Thread Erik van Oosten


Excellent! That is only 4 blocks from where I work :)

Also, all those dates are fine by me.

Just an opinion: I do not expect any presentations; just a get together 
for a couple of hours is nice.

Do you think the dates and location I suggested will work?

These are the dates I made a reservation for:

Friday November 23rd
Monday November 26th
Friday November 30th

I didn't book any rooms yet, I just called the venue to ask which dates are 
still open and block them in the meantime. When we say GO for any of these 
three days, they'll book it for us. However, if someone has a better idea, 
please speak up! :)
The venue is right in the center of Amsterdam,

Best approach to localization

2007-10-04 Thread Cristina


Hello,

the *pub* example (http://wicketstuff.org/wicket13/pub/) shows how a
localized string can be retrieved from a properties file and then
dinamically inserted in a page. Still, with the exception of that string,
the remaining markup is kept static, which results in separated, localized
HTML files for each locale.

So is this the current best practice regarding localization in Wicket? Or
would it be better to replace all static UI labels with dynamic Wicket
labels such that their localized values are defined in the corresponding
properties files? I'm asking because the 2nd option, even though it allows
the production of a single HTML file for all locales, obviously has a higher
development cost... Would the benefit be high enough to justify that choice?

Thanks so much,

Cristina

Best way to go is probably to use wicket:message tags for static
blocks that need to be localized.
