At the moment though I'm creating a HashMap of values to put into
freemarker directly in the Filter (just for testing purposes), whereas I
really want to create a HashMap in the page I'm currently generating and
either pass, or make it available to the filter, but I can't think how I

So, how to I get data from the Page Class I have to the IResponseFilter?
All the examples I could find, just use data directly available from the

Re: [Wicket-user] Model for form with variable number of fields

2007-08-04 Thread Igor Vaynberg

dont use a compound model, that is just a shortcut for common cases.

create a model that keeps an index and a ref to the list model, and pulls
things in and out like that.

class indexedmodel implements imodel {
  private final imodel list;
  private final int index;

  getobject() { return list.getobject().get(index); }
  setobject(object o) { list.getobject().set(index, o); }
  detach() { list.detach(); }
}

and pass one of those to the dropdownchoice

 Hello,

 I have a process that reads a CSV data file.  The data contains lists
 of people, but the number of fields, the order and the type of fields
 can vary from one CSV to another.

 Because the data in each column is unknown, a form is displayed with a
 preview of the data in a table.  The table column headers contain
 dropdown list of possible field types for each column in the csv file.
 I'm using a RepeatingView to generate the headers.

 The problem is, I'm unclear how to design the CompoundPropertyModel
 for the form.  I assume my model needs to contain a collection of some
 sort since I have a varying number of field.  But how do I map the set
 of RepeatingView-WebMarkupContainer-DropDownChoice objects to the
 model as a collection?

 Here's the code:

 preview = importer.previewImport(new FileInputStream(dataFile),10,2);
   ...
 RepeatingView headers = new RepeatingView(header);
 form.add(headers);
 int numFields = preview.getRecords()[0].getFields().length;
 for (int j = 0; j  numFields; j++) {
   WebMarkupContainer cell = new WebMarkupContainer(headers.newChildId());
   headers.add(cell);
   cell.add(new EdiCriteriaDropDownChoice(criteria).setRequired(true));
 }

 And the markup:

 table cellspacing=1
   tr
 th wicket:id=header
 select name=select
 wicket:id=criteria/select
 /th
   /tr
...
 /table

 What kind of model would work with this?

 Thanks,
 Tauren

Re: [Wicket-user] DownloadLink for an external URL

whatever streams that external file has to set a

 I see that DownloadLink can be used to stream a File.

 What I want to do is use DownLoadLink to redirect to  an external URL
 that should be streamed (i.e. File Save box should pop up).

 I can't use ExternalLink as the external URL's location is not pre
 determined,
 also the external URL's location lookup is a costly so I don't want to do
 it unless
 the User clicks on a link.

 So in my case I do some thing like

 class DownloadUrlLink {

 onClick() {

   URL externalUrl = getExternalURL(); //this is a costly operation, so I
 don't want to do it unless user clicks the Download link.
 getRequestCycle().setRequestTarget(new RedirectRequestTarget(url.toString
 ()));

 }

 }

 The URL points to a rather large gzipped XML file about 11MB in size.
 But instead of popping up a File Save dialog, the browser starts to
 display the XML file.
 and CPU usage jumps up to 100%, on account of the file being this large.

 Is there a way to force the browser to pop up a FileSave dialog when using
 RedirectRequestTarget

Re: [Wicket-user] How to set a date on backing model obj from contents of drop down lists?

2007-07-31 Thread Igor Vaynberg

if you really want something that binds to the Date then create 3 models,
each adjusting the specific portion of the date, for example:

class YearModel implements IModel {
 private final IModel date;

  Object getObject() {return date.getObject().getYear();}
  void setObject(Object o) { date.getObject().setYear((Integer)o); }
   void detach() { date.detach(); }
}

 One suggestion: what about having a date pojo like:

 public class MyDate
 {
   get/setMonth()
   get/setDay()
   get/setYear()

   public Date getDate()
   {
  // translate object state into a Date object
   }
 }


 Then use PropertyModel to get/set the individual fields:

 Component myComponent = new WhateverComponent( id, new
 PropertyModel( myDate, fieldOfDate );


 That should work.


 Maybe more experienced people know of a more elegant way, though this
 way's not so bad.


 Cheers,
 Dave

  Hi all,
 
  Sorry for the potentially noobish question, but I'm not sure how to
  go about this in Wicket...
 
  I need to set a Date on a form's model object by way of three drop
  down lists.  The drop downs look something like this:
 
  Drop down 1 contents:  Month, January, February, ..., December
  Drop down 2 contents:  Day, 1, 2, ..., 31
  Drop down 3 contents:  Year, 2007, 2006, ..., 1907
 
  Clicking the Submit button on the form will save a single
  java.util.Date object on the form's backing model object based on the
  aggregate values of the three lists' selections.
 
  Thanks for any suggestions,
 
  Justin

use ajax submit button

Re: [Wicket-user] onBeforeRender on every Request?

2007-07-30 Thread Igor Vaynberg

onbeforerender() works recusively

lets look at your code

protected final void onBeforeRender()
{
   super.onBeforeRender();
org.apache.wicket.markup.html.WebMarkupContainer tabPartRepeater = (
org.apache.wicket.markup.html.WebMarkupContainer)this
.get(tabPartRepeater);

tabPartRepeater.removeAll();
this.populateTabParts(tabPartRepeater);
this.setupContentPanel();
}

the problem here is you call super.onbeforerender(), then create more
components - so onbeforerender() wont be called on those newly created
components because it would cascade in super.onbeforerender().

to fix all you need to do is move super.onBeforeRender() to the end of the
method.

On 7/30/07, Flavius [EMAIL PROTECTED] wrote:

Greetings.

I have a page that uses the new OnChangeAjaxBehavior. When values
are typed into the text field, it updates a RepeaterView. It works
with the first key press but, almost always, it doesn't fire the
onUpdate()
event on subsequent key presses, but only on FireFox (I'm using 2.0.0.5).

It works fine with IE 7. To make sure I didn't configure anything
incorrectly,
I copied the OnChangeAjaxBehaviorPage sample to my project and ran it.
That works fine for both IE and FireFox. Since I can reasonably eliminate
environment, it seems like the probable issue has something to do with
the repeater code, or its container. In looking at the AJAX DEBUG window
it looks like the ajax is completing successfully.

I'm using the wicket 1.3.0-beta2 build. I also tried now with the
snapshot from today (561103). The same results.

I put up a test page at http://24.248.103.44/pages/TestAjax. The
page has the java code on it.

IE works fine, but FF fails after the first key press.

I also have the sample from examples too:

http://24.248.103.44/pages/OnChangeAjaxBehaviorPage

That works for IE and FF.

I'd appreciate any insight into what I may be doing wrong.

 Is it possible that I am missing something on logout action?
 Is it enough to do session.invalidate()?

 Note, it works properly the first time, only after I log out and then go

 Hi all,

 On my development box, the following code works fine (I'm using a Wizard):

 if (getProduct(validatable.getValue()) == null) {

 If I enter an invalid code, the error message is correctly displayed,
 and the log correctly shows the message in the FeedbackMessages list.

 However, when I deploy the application the Validator is still called,
 and the both LOG lines appear, but the FeedbackPanel never renders on
 the page.

 I've tried running locally in DEPLOYMENT mode, and in both Tomcat and
 Jetty but it has made no difference - it always works fine on my
 computer and fails on the live servers.

 Has anyone come across this problem before - or can someone suggest a
 place to look to start fixing this?

Re: [Wicket-user] RequestCycle goes null after using WicketTester within Wicket page

because of all the threadlocals you should probably run wickettester in a
separate thread:

onclick() {
 final String[] output=new String[1];
 Runnable gen=new Runnable() {
   run() {
  WicketTester tester=new WicketTester();
  tester.startPage(new MailPage());
  output[0]=tester.getoutput();
 }
   }
   Thread thread=new Thread(gen);
   thread.start();
   thread.join();
   // output available in output[0]
 }
}

 Essentially, I'm trying to use WicketTester to hit a page in order to get
 the page's final rendered HTML (so I can use it in an email). It works,
 but
 within the process the object in RequestCycle.current disappears for some
 reason. The initial page that is being processed explodes. Is there
 something I can do to prevent this? I tried instantiating a new
 WebRequestCycle, but it resulted in an infinite loop (perhaps I
 constructed
 it poorly, though)...


 A snippet:

 class SomePage extends WebPage {
   public SomePage() {
 CaptureApplication app = new CaptureApplication();
 WicketTester tester = new WicketTester(app);
 tester.startPage(AnotherPage.class);

 //Everything's fine through here...but after...ASSPLODE!
   }



   class CaptureApplication extends WebApplication {
 public Class getHomePage() {
   return null;
 }

 protected IRequestCycleProcessor newRequestCycleProcessor() {
   return new InterceptingCycle();
 }

 class InterceptingCycle extends WebRequestCycleProcessor {
   public void respond(RequestCycle requestCycle) {
 StringResponse emailResponse = new StringResponse();
 WebResponse originalResponse = (WebResponse)
 RequestCycle.get().getResponse();
 RequestCycle.get().setResponse(emailResponse);

 super.respond(requestCycle);

 System.out.println(emailResponse.toString());

 RequestCycle.get().setResponse(originalResponse);

Re: [Wicket-user] Wicket 1.3, use of getElementById and Wicket.$() and the preservation of ids

2007-07-26 Thread Igor Vaynberg

the general problem here is that hardcoding ids into wicket markup is mostly
dangerous because things are so reusable.

if you put an id into a repeater then it will be repeated all the time -
causing multiple elements with the same id - which will lead to invalid
html.

hardcoding an id inside a panel or a fragment will lead to the same problem.
it isnt something obvious until you start reusing code and then it gets
nasty all of a sudden. so my two cents are to discourage this.

however, as a workaround for cases where you _must_ do this we have
component.setmarkupid(string) in trunk - you can use that to force any id
you want.

Yeah, they were listed in the thread that is mentioned in the issue:

http://www.nabble.com/Re%3A-getMarkupId-doesn%27t-return-the-id-from-the-markup-p11294903.html

I don't really know what to do with it tbh. I hope someone else has
some suggestions.

I'm a little surprised this isn't more of a high priority item... I
know Repeaters et al might need some special casing, but could the
usual cases do what the coder probably expects, i.e. if you specify
in html markup, that id is preserved (and therefore usable in
javascript's getElementById ??)

Or... I'm not sure what else might depend on that Id as it gets spit
out into what's finally sent to the browser, but maybe there could be
a some kind of mapping function in javascript,
.getElementByWicketId(id)? and
getRepeaterElementByIdAndIterationNumber(id,num)
(I tend to make my function names a bit long :-)

As a thinking point, my group has come up with 3 possible workarounds
until the real solution appears:
* temporary, awful hack bandaid currently in use: our javascript
getElementById added a 6 to the id... the fragile nature of this
fix is not lost on us
* go through some function along the lines of getElementByPrefixOfId()
, so we can get what was specified
* every form has a hidden field like input type=hidden
name=OUR_ID value=XYZ, and then we have a specific
getFormByOurId()

Again, I'm not sure what getMarkupId(Component) is called by, if it's
mostly wicket internal use or what... most of what I've talked about
here is javascript workarounds, though i guess the underlying Java
equivalents should be obvious.

 if you're writing custom javascript (in this case an arbitrary form
 element that needs to submit a hidden form for an ajax interaction),
 is there a way that preserves the id as set in the .html
 wicket:id=XYZ as the HTML element's id? In this case, when the .html
 is processed by Wicket, the resulting id is something like XYZ6

 Googling on
   wicket getElementById
 it seems that might be deprecated for javascript inside Wicket,
 there's that Wicket.$(id) syntax instead? But I couldn't find
 documentation on that, and both getElementById() and Wicket.$() worked
 with XYZ6 but not the original XYZ.


tbh, you are not meant to use anything inside wicket-ajax.js directly.

Pointers to the documentation I wasn't able to find appreciated as

Re: [Wicket-user] FormComponentPanel with setRequired

2007-07-26 Thread Igor Vaynberg

i just made formcomponent.checkrequired() none final.

i think most implementations of formcomponentpanel will want to override it
and always return true. that way required validation will be performed on
formcomponentpanel's convertedinput rather then raw http post input. makes
sense?

 For example I made a FormComponentPanel made of three DropDownChoice to

 But if i make this FormComponentPanel required it never get validated,
 because its input is always null..

 I tried to overload isInputNullable for returning false, but didn't

 a good way to me..

 Any hints?

 I have a Panel that I'd like to be able to either render as a

 At first, I thought this would work:

   WebMarkupContainer formHeader =
   new WebMarkupContainer( FORM_HEADER_ID );
   add( formHeader );
   formHeader.setVisible( form == null );

 but then I realised that this won't work, since only the form header (or

 and closed).

 I can think of a few hacks to make this work, but can somebody suggest a
 more elegant solution to this?

Re: [Wicket-user] Wicket customizability

2007-07-25 Thread Igor Vaynberg

sounds to me like what you need is indirection

something like

IComponentFactory { Component newComponent(String id, IModel model); }

then you can configure these in whatever context (in your case spring) and
inject those into pages/panels/etc and let them create children.

this is essentially the same as osgi or anything else would work. a named
component factory is an osgi service/spring bean/plugin/whatever

 Hi all,

 I have just created my first wicket app: a simple JCR (jsr-170)
 browser/editor with a tree showing nodes on the left, a
 form for editing node properties on the right, and a menu with some
 actions (add, delete, save etc.) on top.
 All 100% Ajax, it just works!

 As a side note: I started from scratch (completely new to wicket), and it
 took me two weeks to learn wicket and build
 the application. Needless to say that I'm a definite a convert, thank you
 guys for creating this wonderful thing called
 wicket!

 Now for my question(s):

 What my shop actually needs is a customizable gui. We develop a core
 module and users can write plugins for it, think
 eclipse, firefox etc.

 I know of Pax Wicket which is an An OSGification of the Wicket web
 framework. It sounds very interesting and reading
 the documentation it looks like exactly the thing we need. However
 creating a 'Pax Wicket' application is something very
 different from an ordinary Wicket app. I have the impression that 'going
 OSGi' is a decision comparable to 'going J2EE'
   and should not be made overnight, but I might be wrong there.

 I would prefer a simpler way of going this. Therefore I did some
 experimenting and tried to inject a wicket Component (a
 Label) with wicket-spring, but found that injecting Wicket Components
 doesn't work. The proxy will try to access a
 protected method on Component and fail. My guess is that that is a Good
 Thing because you're not supposed to inject
 wicket Components this way, but I may be wrong there, am I? Is there
 another way?

 What I did manage with just base Wicket was a custom
 ModalWindow.PageCreator that dynamically loads a Page (using
 Class.forName) in it's createPage() method. That works, and because the
 class name is stored in the Model (it's a
 property of the selected node in the tree) I now have a 'dynamic' modal
 window whose implementation (java + markup)
 depends on the selected treenode and can be plugged in by adding a jar
 file to the project.

 However, extensibility 'just' through popup dialogs is not enough, and as
 far as I understand it is not possible to do
 the same trick for 'inline' (on the main Page) Components. Or is it?


 I guess that my question boils down to this: Am I on the right track or
 should I stop doing this and go to my boss and
 tell him that we should go OSGi (and Java 5 btw. currently we are strictly

Re: [Wicket-user] Custom session not working...

Thanks Eelco, that did the trick.

Couple of follow up questions/comments that anyone can field:
1) I understand why you would want a stateless application, however I
don't
understand why you would ever want your session to be regenerated on each
request if during the request you specifically set a session value. It
seems like once you set a session value, the session should become bound.
Is there a logical reason this isn't the case, or is it just a
technological/implementation reason? I'm just trying to understand this
better.

after you set the value on the session did you call session.dirty() to let
wicket know you have done that? i think dirty() will bind the session as
well.

-igor

2) The location quoted for the live examples
(http://wicketstuff.org/wicket13/) is the one I was looking at, however
for
the specific example stateless, it is not possible to view the source
code
and/or page files live. Not sure how the site is maintained, but
perhaps
a download link could be added on the examples page to the build that the
live examples demonstrate, by default. I've got the files now however, so
thanks again!

Best regards,

Spencer

Eelco Hillenius wrote:

I have a custom session class that inherits from WebSession. I have
overridden the newSession method in my Application class. The session
is
getting used during the request, because I initialize some of its
values
in
its constructor, and they show up when I attach a label to them in a
page.
A new session gets created with every request, however, which obviously
is
not the desired behavior. For instance, I have an Integer, and I
initialize
it to 1 in the constructor, and increment it before each page
display. I
always get back a 2 on the page.

It sounds like your page is stateless, and the session instances are
temporary. As long as a session is not 'bound', you'll get a separate
instance per request and Wicket won't hold on to heap memory. You can
force the creation of a session by calling Session#bind, which I think
you should be able to call from your constructor as well.

Related to this, can someone provide me a download link to the 1.3
examples?
The live examples page does not allow you to view the source for the
stateless example, which seems like it may have some relevant code in
it,
and I cannot find a download link for the 1.3 examples. The 1.2examples
do
not have that particular example, from what I can tell.

Use http://wicketstuff.org/wicket13/ to look at the examples. The
wicket-examples site is stale.

As for downloading the examples for 1.3.0, at this time you can best
get them from SVN directly, or download them from our maven repo at

http://wicketstuff.org/maven/repository/org/apache/wicket/wicket-examples/1.3.0-SNAPSHOT/

So, this means that I can't repaint a DataTable by row and I also can't

Excellent!

Now, is the issue I describe above worthy of attention? Since I can now
repaint a row, this problem won't affect me, but it still seems valid.

 Both suggestions are good. As far as I know,

yep, setoutputmarkupplaceholdertag() was actually created just to make a

often added just to have an always-visible tag in markup to repaint.

Re: [Wicket-user] Modal Window and Page Expired - SOLVED

2007-07-20 Thread Igor Vaynberg

On 7/19/07, Laurent Brucher [EMAIL PROTECTED] wrote:

 Ok, my bad...
 Cutting out the details, the page that included a ref to the modal window
 had a piece of javascript, which generated an IMG tag with a src
 attribute
 starting with a '#' (this is some code ported from a JSF version of the
 application). The browser was then trying to fetch the page again looking
 for the (inexistent) bookmark, hence the double hit to the page.

 Now, I'm wondering if it is normal that the framework evicts the page when
 removing one of the 2 versions of that page from the access stack since
 the
 other version is still there and may be referenced again. But I don't know
 wicket enough to make a valid statement on this.


well, the idea here is that we can evict it because it is no longer
reachable via the browser. for example you go to page A then go to page B,
then click back and go to page C. you can no longer access page B via the
browser, so wicket evicts it from pagemap since at that point its just
wasting space. however when you have the kinds of problems you have it
becomes a pita to figure out whats going on.

 Subject: [Wicket-user] Modal Window and Page Expired.


 Hi all,

 There was a post last December about the same problem that I'm facing
 right
 now, which is getting a page expired error page after I close a modal
 window.
 The post was called Firefox and ModalWindow and seemed to talk about the
 issue for FF only.
 I've encountered the problem first with FF (2.0.0.4). After reading the
 post, I tried with IE7 and it worked ok (that was this afternoon).
 This evening, neither IE7 or FF work anymore. Darn! Clearing cookies and
 stuff don't change a thing.
 Oh, and of course, the Ajax ModalWindow example works just fine (my code
 is
 heavily inspired from that example)...
 I'm using Wicket 1.2.6, Tomcat 5.5.20, Jdk1.6u2.

 Have you guys shed any light on this issue at all?
 I've tried to trace the code, but as I'm rather new to Wicket, I couldn't
 really figure out what's going on...

 Anything I can do to help address this?
 Below is the code I use, just in case.

 Reagrds,
 Laurent.


 // Page containing the modal window
 public class MainPage extends WebPage {
 public MainPage()
 {
 ...
 add( new PreferredStationsDialog(prefStationsDialog) );
 ...
 }
 }

 // The modal window impl.
 public class PreferredStationsDialog extends ModalWindow {
 public PreferredStationsDialog(String id)
 {
 super(id);

 setTitle(xyz);
 setCookieName(prefStationsDialog);
 setPageMapName(prefStationsDialogPageMap);
 setPageCreator( new ModalWindow.PageCreator() {
 @Override
 public Page createPage() {
 return new
 PreferredStationsDialogPage(PreferredStationsDialog.this);
 }
 });

 setCloseButtonCallback(new ModalWindow.CloseButtonCallback() {
 public boolean onCloseButtonClicked(AjaxRequestTarget target)
 {
 return true;
 }
 });
 }
 }

 // The content of the modal window, as a Page
 public class PreferredStationsDialogPage extends WebPage
 {
 public PreferredStationsDialogPage( final PreferredStationsDialog
 dialog
 )
 {
 super();

 add( new AjaxLink(button.save) {
 @Override
 public void onClick(AjaxRequestTarget target) {
 dialog.close(target);
 }
 }.add( new Label(text, Save)) );

 add( new AjaxLink(button.cancel) {
 @Override
 public void onClick(AjaxRequestTarget target) {
 dialog.close(target);
 }
 }.add( new Label(text, Cancel)) );
 }
 }

he problem here is specifying the charset, properties factory is global so

Re: [Wicket-user] Question regarding dropdownchoice

2007-07-19 Thread Igor Vaynberg

On 7/19/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote:

 Hello to all!

 I'm beginning to learn how to use wicket and I have a question regarding
 DropDownChoice: I have a POJO that is serving me as the model for my
 page, so my form is bind to the properties.
 My problem with the Dropdownchoice in this case is: even if the property
 in the POJO is filled exactly with the same string as the dropdown, I
 never have the proper value selected. It is always selecting that
 Choose One option. So , the question really is: what I need to do to
 have this working properly?


 Follow below the source code for this situation:
 public class User {
private String userName;
private String userType;

   public User() {
   this.userType = General User;
   }

 /* getters/setters */
 }

 Now, I'll create a page and bind this POJO in the interface:
 HTML:
 html
 headtitleTest Page/title/head
body
 form wicket:id=testForm
   User Name: input type=text wicket:id=userNamebr
  User Type: select wicket:id=userType
 optionDemo 1/option
 optionDemo 2/option
/select
/form
   /body
 /html
 JAVA:
 public class TestPage extends WebPage {
private String[] options = new String[] {new String(Test User), new
 String(General User)};
private List OPTIONS = Array.arrayAsList(options);
 public TestPage() {
  User user = new User();
 CompoundPropertyModel userModel = new
 CompoundPropertyModel(user);
  Form testForm = new Form(testForm, userModel);
  TextField userName = new TextField(userName);
  DropDownChoice userType = new DropDownChoice(userType, new
 PropertyModel(userModel,userType), OPTIONS);
 testForm.add(userName);
testForm.add(userType);
   add(testForm);
}
 }


set a breakpoint in abstractsingleselectchoice.isselected() and see why it
is returning false

futher, since you are using a compound model this

 DropDownChoice userType = new DropDownChoice(userType, new
PropertyModel(userModel,

 userType), OPTIONS);



can be changed to

 DropDownChoice userType = new DropDownChoice(userType,OPTIONS);

Re: [Wicket-user] Repaint single row of a DataTable

2007-07-19 Thread Igor Vaynberg

this is tricky because datatable encapsulates a lot of this stuff so it will
probably need something exposed for this usecase. if you create a quickstart
that has a datatable, some bogus data, and some links in columns that should
trigger a refresh i can play around with it and see what needs to be done.

-igor


On 7/19/07, ChuckDeal [EMAIL PROTECTED] wrote:


 I searched for answers to this problem, but most responses were to repaint
 the whole table (or more specifically, the container holding the table).

 I am trying to make an editable grid.  In addition to that, when some cell
 contents change, other cells may need to be repainted (they might contain
 computed values based upon values of one or more other cells).  For
 performance, I don't want to repaint the entire table on each keypress,
 but
 repainting the single row won't be so bad.

 What could I do to repaint a single row of a DataTable?  Don't use
 DataTable?  but I think I still want a repeater and ultimatley it is the
 repeater's fault that I can't repaint because the MarkupFragmentFinder
 can't
 grab the markup because it uses the component's id to match up to the
 markup it finds and the id of repeater children will never match.  It
 would
 need to know that it is a repeater child and use it's parent it to match
 the
 markup.  Component.renderComponent is final and new MArkupFragmentFinder
 is
 hardcoded in there, so it doesn't look like I can create a custom
 MarkupFragmentFinder impl for this special case.

 Maybe I am seeing this from the wrong perspective?  Could someone suggest
 an
 alternative to this approach?  Basically, I like Datatable because it
 allows
 me to define each cell (and any number of them), but I want the ability to
 repaint only PART of the table...

 Thanks

what you should do is instead of returning an iterator directly first copy

 Any thoughts?


first try 1.2.6 branch. i know this is a problem that happens somewhat

what does your strategy do? it redirects right? you do that with throw new
RestartResponseException - you can do the same from your constructor once
you check your model. it isnt that much later that you would fail - only

True you can't do setModel(foo) and expect your instantiation check

work. Which imho is perfectly logical if you want to use your model
 in
the instantiation check you need to pass it in the constructor.
   
As for the example
We have a search page for students, uppon clicking on one of those
students, you go to a detail page for that student. that page also
contains several tabs to go to other relevant pages for the student
(like it's school grades). on these pages we made a quicksearch
function with contains amongst other things 2 buttons to navigate
forth and back between the searchresults of the search page, while
keeping the same view. Suppose i have sufficient rights to see the
detail pages of all students but only enough rights to see the
 grades
of my own students.
   
So if i make the search wide enough to get all students and then
select one of my own, going to the grades. That's fine. But if i
 then
navigate to another student i am not allowed to see the grades
(creating a new instance of the grades page in the process) i need
 to
know if the page in combination with the student is allowed, because
the page itself is basically allowed.

2007-07-18 Thread Igor Vaynberg

i am -1 on this

first of all there are already too many exception to this: it wont work if
its a wrap model, it wont work if its icomponentassignedmodel, blah blah
blah.

if i construct my component with new Component(id, foo) and foo is not
null then it is very clumsy that sometimes in the auth strategy it is all of
a sudden null and other times is not even though the exact same line is
executing. i bet a lot of people will be filing bug reports.

also i really wish we would limit passing around instances of not fully
constructed objects to users. we already do it in some places where it is
very strictly necessary, but we should not do this lightly.

i do not wish something like this introduced just to make maurice's life a
little easier, sorry maurice nothing personal.

 I don't think I agree with that.

 MyComponent c = new MyComponent(); c.setModel(foo) wouldn't work for
 starters, and you can even set models mutliple times. Not to mention
 the other problems you mentioned in this thread. And finally, it would
 just invite people to go crazy with this functionality.

 But give us a good example of where using the model to determine an
 access restriction would actually be useful?

Re: [Wicket-user] Nesting AjaxTabbedPanels when using AjaxLink

2007-07-18 Thread Igor Vaynberg

On 7/18/07, Jeff Pierce [EMAIL PROTECTED] wrote:

 I am new to Wicket and just getting my feet wet and looking for some
 advice.  I have an app I am building that contains a main row of Ajax tabs
 across the top.   Each tab's panel will have the following layout.  A set
 of
 menu's on the left and a set of tabs on the right for part of its content
 area.  I want the menu's to be Ajax links and the tabs to be Ajax tabs.
 When the user clicks on a menu choice, the content area should reload with
 a
 different set of ajax tabs.

 My question is what is the best way to hookup the ajax links to change the
 portion of the page that contains content area which includes a different
 set of tabs depending on the menu choice (stuff in red below)?  I have the
 tabs and subtabs loading OK, but not sure how to go about hooking up the
 ajax menu choices to change the subtab panel.

 Here's the basic layout:

 -
 Page header area
 -
 | *MainTab1* | MainTab2 |
 -
 |*Menu1* |
 | Menu2  || *Menu1Subtab1* |Menu1Subtab2|
 | Menu3  ||
 | Menu4  ||
 |||  Menu1Subtab1 Tab panel Content Area
 ||
 -
 Page footer area
 -


you have to replace the entire tabbedpanel that holds the menu1subtab links.

so menu1link.onclick(target) {
ajaxtabbedpanel newone=new menu1tabbedpanel(...);
menutabbedpanel.replacewith(newone);
menutabbedpanel=newone;
target.addcomponent(newone);
}

 Sounds to me like you have alternative ways to implement this, for
 instance, construct what's on your page according to what can be

 intermediate page that functions like a switch. Also, if you really
 want to follow your approach and IComponentInstantiationListener is
 not rich enough, consider using AOP, which should give you all the
 freedom you wish for.


i think its time for you to build something that uses aop and get it out of

Re: [Wicket-user] Overriding ID attributes

2007-07-18 Thread Igor Vaynberg

On 7/18/07, mperham [EMAIL PROTECTED] wrote:


 We are migrating our existing application from UI framework XXX to Wicket
 and
 we have a boatload of UI automated tests which depend on the ID attribute
 of
 our form inputs to drive the tests.  I'm trying to figure out how to get
 Wicket to use the exact same IDs when it generates the HTML as with our
 old
 system.  Here's an example of the generated HTML where I have a DropDown
 within a Form:

 td class=label
 divlabel for=form_selBusinessServiceBusiness
 Service/label/div
 /td
 td class=input
   select name=selBusinessService id=form_selBusinessService
 option selected=selected value=Choose One/option
 option value=http://www.test-sdk/sdkl#Fetch_COB;Fetch COB/option
 option value=http://www.test-sdk/sdkl#Status_Visibility;Status
 Visibility/option
 option value=http://www.test-sdk/sdkl#Claims_Submission;Claims
 Submission/option
   /select
 /td

 Now the actual ID of the select should be selBusinessService and that's
 the wicket:id of the component in Java but Wicket prepends the component
 hierarchy, I guess, when auto-generating the id attribute in HTML.  Now I
 can use an AttributeModifier to adjust the value of the ID but the
 SimpleFormComponentLabel does NOT reflect that change in the for
 attribute.

 Is it possible to do this?  Can I completely override Wicket's ID handling
 and just have it use my specified ID?


not right now, but creating setMarkupId() wont be very difficult. please add
a jira request.

i dont remember how similar the markup id handling code is between the two

/**
 * Sets this component's markup id to a user defined value. It is up to
the
 * user to ensure this value is unique.
 * p
 * The recommended way is to let wicket generate the value
automatically,
 * this method is here to serve as an override for that value in cases
where
 * a specific id must be used.
 * p
 * If null is passed in the user defined value is cleared and markup id
 * value will fall back on automatically generated value
 *
 * @see #getMarkupId()
 *
 * @param markupId
 *markup id value or null to clear any previous user defined
 *value
 */
public void setMarkupId(String markupId)
{
if (markupId != null  Strings.isEmpty(markupId))

throw new IllegalArgumentException(Markup id cannot be an empty
string);

the view doesnt keep the iterator, it just iterates over it once when it

 The gist of it is, that a whole bunch of users will be reading all the

 progress through the Vector ...

 The only actions I performed on the vector is adding to it.  I am
 thinking,
 once the iterator is retrieved from getItemModels() does RefreshingView
 store the iterator within itself for the duration that its being
 displayed?

Re: [Wicket-user] Setting up project - images and stylesheets

2007-07-18 Thread Igor Vaynberg

simply do this

have your images be relative

img src=images/logo.png/

in runtime wicket will rewrite them to be relative to context root

in devel time put this into head

wicket:remove
base href=../../../path/to/your/webapp/folder/
/wicket:remove

so at devel time your images will also be relative to context root.

...and I run the application, the image will reference
web/images/logo.png.
However, if I just quickly view that HTML file, it will reference
src/java/package/images/logo.png and the image link will be broken.

Is there a good way to set up the project besides keeping duplicate images
and stylesheets both in the source code dir and the web dir?

I realize if I move the HTML files to the web directory the problem will
be
solved but I'm trying to stick with the Wicket way of doing things for now
(.HTML right next to .java in the source)

Re: [Wicket-user] Disabling Validation, but keeping updateFormComponentModels()

2007-07-17 Thread Igor Vaynberg

On 7/17/07, Fisher, Brice A [EMAIL PROTECTED] wrote:

 An additional question.  Trying to do things the brute force way, I
 implemented the following in my form:


 @Override
 protected void validate() {
 Button b = findSubmittingButton();
 if (b == updateButton) {
 super.validate();

 // Additional validations...
 } else {
 updateFormComponentModels();
 }
 }


 If the else branch is taken, then the fields from the form are null.
 If I switch my RequiredTextFields to TextFields and force the if
 branch, then the form fields are correctly populated.  So, apparently
 there is more happening in super.validate() than is covered by
 updateFormComponentModels().

 However, if I look at super.validate(), it includes:

 validateRequired();
 validateConversion();
 validateValidators();
 validateFormValidators();

 None of which are available in the inherited class.

 So, should I plan on re-implementing the contents of one or more of
 these functions in my class or is there another method I can call to
 correctly populate the form elements?


you cannot update models without validation. a simple example:
you have TextField(number, Integer.class); and the user enters a.
obviously you cannot put a into a model that expects an Integer.

 defaultSystemLanguage.setNullValid(true);

 CompoundPropertyModel:
 private String defaultSystemLanguage; (with gets/sets)

 onSubmit:
 public void onSubmit() {
System.out.println (LANGUAGE BY DEFAULT: +
 userInformation.getDefaultSystemLanguage());

 This causes the following error:

 wicket.WicketRuntimeException: No get method defined for class: class
 java.lang.String expression: languageID

 What I'm doing wrong? If I specify a CompoundPropertyModel with one
 property
 with the same name as the DropDown, isn't supposed to be mapped directly
 there?


your model object is of type String as it maps to the String
defaultSystemLanguage. your renderer however expects an object it can call
getLanguageName() and getLanaguageId() on - as you have defined. so make
defaultSystemLanguage your Language object instead of just a string.

Re: [Wicket-user] AjaxRequestTarget.addComponent for a child of ListItem

2007-07-17 Thread Igor Vaynberg

Hello, I've seen the posting that refers to this wiki page
http://cwiki.apache.org/WICKET/how-to-repaint-a-listview-via-ajax.html How
to repaint a ListView with Ajax but my problem is a little different and
I'm hoping there's a solution. I'm using wicket-1.2.6

I've got a ListView that renders some dashboard icons. Each ListItem of
the
ListView contains a BookmarkableLink which contains WebMarkupContainer
representing a div which contains another WebMarkupContainer representing
an
img. The model object backing the div can change state which should
result
in a change of the img source (ie: change from warning.png to error.png).
Each div is given a unique markupId (via a SimpleAttributeModifier) that
matches the model object's primary key in the database.

There's an AbstractAjaxTimer registered on the ListView who's onTimer
method
iterates through the ListView's children and drills down to the div
component. If the div's model object has changed state, I call
target.addComponent passing in the div component and the div's unique
markupId.

With this methodology, I can't get an individual div to refresh. I put a
div container around the ListView and I can get the entire ListView to
refresh as the wiki page suggests but I'd like to get a tighter
granularity
of refreshing since there may be hundreds of icons on a dashboard. Am I
doing something wrong or is there no way to ajax refresh individual
ListItem
(or their children) components?

any errors in wicket ajax console? also try repeatingview - it is more
stable then listview in the sense it doesnt try to recreate its hierarchy
on every request.

Thanks,
Mike

 Thank you again.

 But I'm not very sure of what you are talking about... I declared the
 DropDowns that way so they are able to change the content for every
 language
 with every localization change. But as part of a Form with assigned
 CompoundPropertyModel, I supposed it should be easy to just map the
 selected
 value in the property with the same name.

 The strange is that I have exactly the same code for a different Dropdown,
 and I can retrieve the value correctly:

 Page class:
   membershipLevels = new DropDownChoice (membershipLevel,
 new LoadableDetachableModel() {protected Object load() {return
 getMembershipLevels();}},
 new ChoiceRenderer (membershipLevelName,
 membershipLevelID));

 Compound Property:
 private MembershipLevel membershipLevel;

 Submit:
System.out.println (MEMBERSHIPLEVEL: +
 userInformation.getMembershipLevel().getMembershipLevelID());

 So yes, you are right, I think I don't understand how it works...


i guess if you can paste thecode to where you createte the model and its
object it might be easier.

there is a good wiki page which goes over how models and compound models
work you might want to read.

dont think @out makes sense anywhere. the ui is/should be a consumer only,
so it shouldnt be contributing back to the context. also scoping out

is a mismatch for seam's scopes.

Re: [Wicket-user] confusion about Wicket models and serialization

2007-07-16 Thread Igor Vaynberg


On 7/16/07, David Rosenstrauch [EMAIL PROTECTED] wrote:



My over-arching question at this point is:  Is it a requirement that a
model's target object be Serializable?



no



1) I tried to use a LoadableDetachableModel, partly as a way to avoid
making my data object Serializable.  But I'm wondering if that's not
correct.  Take for example a data object with gettters and setters for
the following fields:  id (int), foo (string), and bar (string).  Using
  LoadableDetachableModel, I can load the object on demand by id - and
so all I need to do is hold the id in the LoadableDetachableModel, and
can discard the object itself.  Thus the object doesn't need to be
serializable.



correct

However, lets say that a form submission by the user sets

the foo property to foo, and bar property to bar.  And let's say
further that foo is a valid value, but bar fails validation for some
reason - which will keep the user on the same form page.  In this case
won't a logic error result?  Since I'm not retaining (or serializing) my
instance of the data object, but rather loading it fresh from the
database each time, won't the foo value disappear?  Because when the
model needs to access the target object, it wouldn't be accessing a
working copy that had the value set to foo, but rather a pristine
copy from the database that had an old value?



if validation fails the models are not updated, wicket will hold on to input
for you and redisplay it in the form. model updates are atomic in regard to
validation. so you are ok. the only thing to worry when using db backed
beans directly is locking. martijn has a  great example on how to handle
optimistic locking in the form on his blog.

2) How am I to handle the situation where I want to use a new (not yet

saved) instance of a data object as the target for a model?  Since the
object is not yet saved to the database, I can't use a
LoadableDetachableModel to load it fresh from the database every time.
And I can't just have the Model create a new instance each time either,
since it looks like repeated form submissions would wind up discarding
old values?  Is there any way to handle this situation without making my
model target serializable?



see above answer. you can use an ldm and in load() return new instance every
time. also consider creating a simple serializable bean for wicket form that
maps onto your object.

I'm fairly certain that I won't be deploying

Wicket with clustering (or at least not session clustering like with
Tomcat or Terracotta - I might cluster at the database level) so why
should I need to be forced to make all my data serializable?



there are other reasons why you need to make things serializable. first -
everything you put into httpsession - where wicket stores pages - must be
serializable. that is a requirement of the servlet spec.

second, wicket versions your objects to make backbutton work - that means
taking snapshots of objects - which means serializing them.

third, for efficiency wicket takes snapshots of pages and stores them to
disk - which you guessed it, requires serialization.

IModel is in part to allow the dto beans to not be serializable if you do
not want them to.

Re: [Wicket-user] setVesible for the component after onEvent

2007-07-16 Thread Igor Vaynberg


in that case you have to call setvisible, but add the parent of the
component to the ajaxrequesttarget instead

totally stupid question, but i am using wicket.* but there seems to be

why are there two different versions? i am getting my wicket and

1.2.6 is hosted at sf.net and is in wicket.*

wicket moved to apache - which requires the package to be
org.apache.wicket.*

version 1.3 will be the first apache release - so 1.3 beta and snapshots are
in org.apache.wicket.*

ContextImage only exists in 1.3 version, in 1.2.6 you can use
servletresponse to reconstruct the absolute path yourself.

im not even sure you need the hiddenfield stuff, you might be able to do it
directly on textfield/textarea wicket components. just add both of them.
afaik if the tag is hidden via javascript it will not submit its value - so
it should work automagically as long as you display:none one of them.

i dont mind that it is a netbeans project, but i do mind that it doesnt have

quickly.

the idea way to build a quickstart is to use the new maven archetype in svn,
or checkout wicket-quickstart. once you do that modify it to reproduce the

Hey guys,

Ive been reading the apidoc for RepeatingView, and there is one thing that

As taken from the API



http://wicket.sourceforge.net/wicket-extensions/apidocs/wicket/extensions/markup/html/repeater/RepeatingView.html


It says  A repeater view that renders all of its children, using its body
markup, in the order they were added.

Example:

Java:

RepeatingView view = new RepeatingView(repeater);
view.add(new Label(1, hello));
view.add(new Label(2, goodbye));
view.add(new Label(3, good morning));

Yet the code yields, according to the APIdoc

Yields:

  ulligoodbye/lilihello/liligood morning/li/ul

I was under the impression it would be
ullihello/liligoodbye/liligood morning/li/ul??

Done. I called it NonCachingDummyWebApplication.

Re: [Wicket-user] Navigator customization

2007-07-12 Thread Igor Vaynberg


On 7/11/07, nazeem [EMAIL PROTECTED] wrote:



I have the same case where I wanted to customize the navigation toolbar to
add few action menu items as well. So I have written my own version of
AjaxFallbackCustomDataTable by just copying the
AjaxFallbackDefaultDataTable
code in to my package and renaming. There I have commented all addition of
toolbars and I am adding them at the time of declaring it.


public AjaxFallbackCustomDataTable(String id, final IColumn[] columns,
SortableDataProvider dataProvider, int
rowsPerPage)
{
super(id, columns, dataProvider, rowsPerPage);
setOutputMarkupId(true);
setVersioned(false);
//addTopToolbar(new AjaxNavigationToolbar(this));
//addTopToolbar(new AjaxCustomNavigationToolbar(this));
//addTopToolbar(new AjaxFallbackHeadersToolbar(this,
dataProvider));
addBottomToolbar(new NoRecordsToolbar(this));
}

During declaration,

AjaxFallbackCustomDataTable table = new
AjaxFallbackCustomDataTable(employeesAjax, columns, dataProvider, 7);
AbstractToolbar navigationTB = new AjaxCustomNavigationToolbar(table);
navigationTB.add(new Label(newSpan));
table.addTopToolbar(navigationTB);
table.addTopToolbar(new AjaxFallbackHeadersToolbar(table, dataProvider));
AjaxPagingNavigator pgNav = new AjaxPagingNavigator(paging, table);
add(table);

From the above code, it is clear that I have customized the
AjaxDefaultNavigationToolbar to AjaxCustomNavigationToolbar. The markup
html
is also copied and renamed to the same..html. So the problem here is that
I
am trying to add some action menus to the navigation toolbar, at
declaration, but it doesn't work.
navigationTB.add(new Label(newSpan));

I have also modified the markup to contain wicket:id=newSpan.

wicket:panel
tr class=navigation
td wicket:id=span
div class=actionmenu style=float: left; width:
50%;
lt;span
wicket:id=newSpangt;lt;/spangt;

/div
div style=float: left; padding-right:
20px;[navigator-label]/div
div style=text-align: right;[navigator]/div
/td
/tr
/wicket:panel


But I am getting the error that

[2007-07-12 10:24:11,453] [ERROR] [btpool0-2]
[wicket.RequestCycle.step(1043)] - Unable to find component with id

if you look at your markup your newspan is in toolbar.span.newspan not in
toolbar.newspan. so you need to create your own version of toolbar by adding
all the pieces yourself instead of trying to add them to the toolbar so you
have full control of composition.

make your form action point to a bookmarkable page. give that page a

there

Re: [Wicket-user] TabbedPanel tabs instanciation

2007-07-12 Thread Igor Vaynberg


On 7/12/07, Xavier Hanin [EMAIL PROTECTED] wrote:


Hi,

When debugging my application which uses a TabbedPanel, I realized that
one tab was unnecessarily instanciated. After some investigation the reason
is simply because I call setSelectedTab based on the parameters of my page,
but since the instanciation of a TabbedPanel call setSelectedTab(0), the
first tab is always instanciated, even though I don't need to render it.

Do anyone know a workaround for this?



i guess tabbedpanel will have to be rewritten to call setactivettab(0) in
onattach if no explicit call has been made. patch is welcome

Re: [Wicket-user] Is it possible to test Wicket templates out-of-container?

2007-07-12 Thread Igor Vaynberg


On 7/12/07, mraible [EMAIL PROTECTED] wrote:



Is it possible to use Tapestry's parser in tests to verify that template
syntax is correct?



probably yes, wicket also has a pullparser implementation you can use, or
any other html parser. our tests compare string buffer of httpservletrequest
to a prerendered string which isnt ideal, but works for us.

I'd like to run tests (like you do when doing a JSP pre-compile) to verify

syntax w/o having to start the app and find out at runtime.



yeah, see how our tests work.

Also, is it possible to adjust Wicket's template caching strategy? In other

words, is it possible to make it like JSP where there's a timestamp check
to
see if a page has been updated?


I realize I can turn off page caching, but does that make Wicket slower than

a JSP-based solution? Can I provide my own implementation (or configure
the
existing one) to check every 2 minutes?



like eelco said, in devel mode this is the default for markup only. if you
want class reloading there is a reloadingwicketfilter, or whatever its
called. in production reloading templates is rarely necessary. for cases
that require them there are a few solutions: you can do what eelco said and
implement your own markup cache which will change globally how all template
caching works, if you have a requierment where only certain pages/components
need to be reloaded while the app is  deployed you can let them implement
imarkupcachekeyprovider and override the cache key.

Re: [Wicket-user] ListViews dynamic Forms

2007-07-11 Thread Igor Vaynberg


if you enable listview.reuseitems(true) your values should stick. make
addbutton.defaultformprocessing(false).

the idea here is that reuseitems will cause the comeponentpath of textfields
not change - which will cause their name attribute not to change also -
which will cause them to pick up the submitted value from last request. make
sure that all addbutton.submit does is add a value to the ened of the
listview's model.

That URL gets a 404 error. That long name is actually the package and
the class where the css file is stored, that is not an error being so
long.

Also, 'es_ES' is added to the filename, how to remove?

Thanks.



so your main.css is under
classes/es/bytelecom/bujero/web/pages/common/css/main.css ? from the looks
of it thats where it should be.

dont worry about es_ES in the name, since the url is pointing to a wicket
resource instead of the file itself wicket will cascade search:
main_es_ES.css, main_es.css, main.css and should find the last.

media=screen
 /
  wicket:link
  /wicket:head
 
  Also tried with:
 
  wicket:head
  link wicket:id=CSSMain rel=Stylesheet type=text/css
  href=css/main.css media=screen /
  /wicket:head
 
  But in both cases i get this in the code of the response page:
 
  link

href=/Bujero/test/resources/es.bytelecom.bujero.web.pages.common.BaseWebPage/css/main_es_ES.css
  rel=stylesheet type=text/css media=screen/
 
  That URL gets a 404 error. That long name is actually the package and
  the class where the css file is stored, that is not an error being so
  long.
 
  Also, 'es_ES' is added to the filename, how to remove?
 
  Thanks.

 so your main.css is under
 classes/es/bytelecom/bujero/web/pages/common/css/main.css ?
 from the looks of it thats where it should be.

 dont worry about es_ES in the name, since the url is pointing to a
wicket
 resource instead of the file itself wicket will cascade search:
 main_es_ES.css, main_es.css, main.css and should find the last.
