Not all values will be overwritten, and if you don't check for
concurrent updates (your users will try to modify the same object at
the same time!) you are in for some hefty support calls.

And if you disable a field, its value will not be part of the form
processing, also something to take into consideration.

Hibernate and JPA use optimistic locking by introducing a version
field. The first person to save the update 'wins'. The second will not
be able to update (the version has been upped, effectively changing
the logical key for the object, so the update will not find the
record). This version can be stored in your model or even in your form
[1].

Also, how are you going to resolve the relations? Person - Address?
Are you going to create those as well?

I think your approach is novel, but may need some thorough thinking.

 Hi all,

 I'm migrating a spring-mvc project to wicket. In this project domain objects
 are directly exposed to the ui (without DTOs in between). The objects are
 validated using the spring bean validation framework (part of
 springmodules). This module creates a unique Validator (a spring interface)
 from annotations given in the fields/properties of every validatable object.
 Then you inject this global validator to your controllers (in the case of
 spring-mvc) so they can validate their form/command (the bound object). The
 result of validation is an Errors objects, with field errors and global
 errors (more precisely, error codes to be resolved against a messages
 resource). It's pretty easy to map these errors from bean properties to
 wicket component ids. This should be done inside onSubmit(), once the object
 is bound (for example, using a CompoundPropertyModel). So, to recap: domain
 objects directly exposed to the ui, Validator created from annotations in
 validatable domain objects, domain objects bound by PropertyModels, domain
 objects validated by injected validator during onSubmit. Up to this point
 I'm pretty happy with the results, validation is almost trivial with the
 annotations and the valang dsl, and I like it being inside the domain
 instead of tied to the ui components.

 One problem I have due to avoiding DTOs is that most of the time I don't
 want to serialize my form models, because they are (often big) entities with
 lazy loaded associations. So in principle I would use an
 LoadableDetachableModel to load the entity from the repository each time the
 model is reattached. But suppose I'm updating a UserProfile. The first time
 it would be ok to populate the model from the persistent profile to be
 updated. But once the form is submitted there's no point in loading the
 profile from the repository again because its properties would be
 overwritten from those coming from the form anyway. So I'm tempted to
 subclass AbstractDetachableModel so that it loads the profile from the
 repository upon creation, but instantiates a brand new profile to be
 populated from the form upon reattachment. Is there a better pattern for
 this? Anyone has run into the same problem?

 Cheers,
 Carlos

[Wicket-user] Internationalization and DropDownChoice

2007-03-29 Thread Toscano


Hello,

I had the following: one extended DropDownChoice with different languages
and some fields in a form. When the user changes it, I get success in
getting the translation of everything in the page, and also Wicket maintains
whatever the user wrote in the fields, so it's nice. But I have a problem
with one DropDownChoice which cointains countries.
By default, it show the english names of all the countries in the world. In
the onSelectionChanged of the languages DropDownChoice I reload the country
names from the database, and make the following:
 
 countries  = new DropDownChoice(country, getCountries());
 userInformationForm.replace(countries);
 
It works, at the same time I change the language, I get the country list in
that language, but if the user selected one country, I can't maintain his
selection... 

Any ideas? It should be easy as long as the ID of the country is the same...

Thank you very very much for your help,
Oskar

Emne: SV: [Wicket-user] Radio.getValue?


Ok, let me try to explain another way. 
 
If you create a page where you use the radio component. The radios represent 
various kinds of datasets(OLAP cubes in this case but it does not really 
matter). 
 
On monday the 1. march you record with jmeter your test case(jmeter only 
records the http requests). In your test case you must select the retirement 
dataset (which has the value radio5 on the html page).
 
Some time has passed now and you want to run your jmeter test, but on your page 
some of the datasets has been removed (they wasnt needed or was not allowed to 
be shown). So now the page no longer contains the radio with the value radio5, 
and your jmeter test will fail because wicket cant find the radio(another error 
scenario would be if the radios changed order). 
 
So if radio component allowed the use of Ichoicerenderer, it could generate the 
value based on the id of the ichoicerenderer for the particular dataitem. This 
would bring better persistance to the radios. At least when testing with jmeter.
 
Did I do a better job explaining?:) 
 
Some could argue that it's not issue, but it would be very handy to have the 
ability to use the ichoicerender with every component that makes use of the 
value attribute in inputs(havent thought it through though). Because it would 
make it easier to use tools as jmeter.
 
I would suggest that to avoid nameclashing we could use the components 
name.getIdValue as value attribute. I am aware that this would bring in a 
possible vuernability, if duplicate items are inserted and that could cause 
problems i guess?

 Hi

 We are doing some extensive Jmeter testing, and have run into a technical 
 problem regarding radios, which are the following:

 If you had 5 radios on a page at a given time, their value would have been 
 radio1, radio2.. radio5.

 If you then pulled out radio number 4 then the list would be this, radio1, 
 radio2 .. radio4.

 Now only the one previously called radio4 should not have been selectable. 
 This renders our jmeter test pretty vuernable if some of the stuff no longer 
 are available. Im not sure if I can use a ichoicerenderer, looking at the 
 code from getValue, it's pretty hardcoded am I correct?

 If possible i'd like to just use the IChoiceRenderer's getId instead, that 
 should fix the problem.

Re: [Wicket-user] Binding and validating domain objects


Hi Martijn,

Not all values will be overwritten, and if you don't check for

concurrent updates (your users will try to modify the same object at
the same time!) you are in for some hefty support calls.



Concurrent updates won't be common because most of the updated info will be
per user, and only one session could be opened per user. Anyway, in case
they do happen, I will use optimistic or pessimistic locking depending on
the particular scenario (most often pessimistic because concurrent editings
won't be frequent); and it's not always that I care about application-level
transactionality: you and me can start editing A, then you commit A', then I
commit A'', not serializable behaviour, but it would acceptable sometimes.



And if you disable a field, its value will not be part of the form
processing, also something to take into consideration.



Yep, in this case I would use LoadableDetachableModel to load the entity
every time. But it's not that often that my forms show just fragments of the
entire entity. I'm not proposing/asking for a one-size-fits-all solution,
just one that fits a use case like that described for the UserProfile.

Also, how are you going to resolve the relations? Person - Address?

Are you going to create those as well?



Exactly. It's the thing most people do with spring-mvc I guess. There your
request parameters are bound to fresh objects by default (although you could
override formBackingObject() to change that). The associated objects are
created in albis during construction of the main one, and so on recursively.
Binding is then done up to arbitrary nesting levels.


Regards,
Carlos

override formBackingObject() to change that). The associated objects are
created in albis during construction of the main one, and so on recursively.
Binding is then done up to arbitrary nesting levels.



To state this more precisely: relationships that are more of a component
kind (and that will possibly be stored as dependants along the same table as
the main entity) will be created in blank (of course, assuming you're in
fact editing them from the form); combo-like stuff will be brought back from
the database from id each time. I was doing the second using entity--id
PropertyEditors in spring-mvc, still don't know how to get the same with
wicket but I suppose it won't be hard.


Regards,

Carlos

  Hi all,
 
  I'm migrating a spring-mvc project to wicket. In this project domain
 objects
  are directly exposed to the ui (without DTOs in between). The objects
 are
  validated using the spring bean validation framework (part of
  springmodules). This module creates a unique Validator (a spring
 interface)
  from annotations given in the fields/properties of every validatable
 object.
  Then you inject this global validator to your controllers (in the case
 of
  spring-mvc) so they can validate their form/command (the bound
 object). The
  result of validation is an Errors objects, with field errors and
 global
  errors (more precisely, error codes to be resolved against a messages
  resource). It's pretty easy to map these errors from bean properties
 to
  wicket component ids. This should be done inside onSubmit(), once the
 object
  is bound (for example, using a CompoundPropertyModel). So, to recap:
 domain
  objects directly exposed to the ui, Validator created from annotations
 in
  validatable domain objects, domain objects bound by PropertyModels,
 domain
  objects validated by injected validator during onSubmit. Up to this
 point
  I'm pretty happy with the results, validation is almost trivial with
 the
  annotations and the valang dsl, and I like it being inside the domain
  instead of tied to the ui components.
 
  One problem I have due to avoiding DTOs is that most of the time I
 don't
  want to serialize my form models, because they are (often big)
 entities with
  lazy loaded associations. So in principle I would use an
  LoadableDetachableModel to load the entity from the repository each
 time the
  model is reattached. But suppose I'm updating a UserProfile. The first
 time
  it would be ok to populate the model from the persistent profile to be

  updated. But once the form is submitted there's no point in loading
 the
  profile from the repository again because its properties would be
  overwritten from those coming from the form anyway. So I'm tempted to
  subclass AbstractDetachableModel so that it loads the profile from the
  repository upon creation, but instantiates a brand new profile to be
  populated from the form upon reattachment. Is there a better pattern
 for
  this? Anyone has run into the same problem?
 
  Cheers,
  Carlos

[Wicket-user] using fragment inside of form


Hi,

I have a fragment inside of form:
Form form = new Form( form );
Fragment fragment = new Fragment( fragmendId, markupId );
form.add( fragment );

and markup:
form wicket:id=form action=

wicket:fragment wicket:id=markupId
...
/wicket:fragment
/form

It fails with WicketMessage: Markup does not contain a fragment with
id=markupId;. Though using new Fragment( fragmendId, form:markupId ) it
works. Is it a bug?

Re: [Wicket-user] Internationalization and DropDownChoice

2 things:

1. Probably you should use an IChoiceRenderer in addition to your current list.
2. you *replace* the component, and with it the selected value, better
to use a lazy model to retrieve the list of countries, instead of
pushing it to the component

ad 2:

new DDC(countries, new Model() { public void getObject(...) { return
getCountries(); } }, new CountryChoiceRenderer());

 with one DropDownChoice which cointains countries.
 By default, it show the english names of all the countries in the world. In
 the onSelectionChanged of the languages DropDownChoice I reload the country
 names from the database, and make the following:

  countries  = new DropDownChoice(country, getCountries());
  userInformationForm.replace(countries);

 It works, at the same time I change the language, I get the country list in
 that language, but if the user selected one country, I can't maintain his
 selection...

 Any ideas? It should be easy as long as the ID of the country is the same...

 Thank you very very much for your help,

Re: [Wicket-user] using fragment inside of form

Where the fragment is defined is different from where it is used. You
define the fragment outside the form (just as you would do a panel,
but that is in another file). The fragment is then instantiated and
added to the place where it will render itself, in your case: the
form.

Well, if I put the fragment outside the form form:markupId makes sense. So
it seems like markupId must always be the full path from the form.

 If you have nested forms it will fail. Nested forms are not supported

 If you need separate form in modal window in 1.2, the safest bet is to
 use a page inside modal window.

You mean WicketTester? I suppose that you need to know the
wicket component paths to use it. As Igor said, you can
deduce them from the markup, but if there is any confusion,
you can also get your table Component

Component table = wicketTester.getComponentFromLastRenderedPage(table:path);

and then inspect its children with the debugger of your IDE.
This should clear any doubts of the actual paths (which, in
the case of repeaters, have confused me as well).

Till now I am using httpunit to test tables but I would like to test
the wicket component by itself and, more over, the WebPage stays in a
Modal Window and I do not know how to test a page in a modal window
via httpunit.

How's it going with HttpUnit?

As I haven't advertised the Selenium RC integration of
Wicket Bench in several weeks, here goes again:

http://svn.laughingpanda.org/svn/wicket-bench/trunk/wicket-bench-test/src/test/java/test/DictionaryPanelTest.java

I find it to nicely complement WicketTester (of 2.0), and
like the fact that Selenium uses a real browser, unlike
HttpUnit and friends.

[Wicket-user] Calling document.getElementById after refreshing the calling component

2007-03-29 Thread ChuckDeal

I have a scenario where I want to perform an action on the server prior to
issuing a jsform.submit() on the client. I had been using SubmitLink, but
the timing was wrong because I need to tweak some data on the client BEFORE
submitting. I finally got the idea to combine AjaxLink and SubmitLink. I
get the onClick action on the server when the user clicks the button and I
planned on using an AjaxCallDecorator to decorateOnSuccessScript to put the
javascript code to submit the form (from SubmitLink). I believe that I have
it correct now, but I am experiencing JavaScript problems.

I put together this quickstart (minus lib folder) to show the simplified
scenario: http://www.nabble.com/file/7527/quickstart-ajaxcalldec.zip
quickstart-ajaxcalldec.zip

calling document.getElementById('form_id') returns null when the success
script fires. Based upon the quickstart that I put together, I think it is
because I am refreshing the component that is firing the event to begin
with. Could someone with more experience in this give it a looksee?

Also wicket-examples source code should be open in another

Re: [Wicket-user] Ajax error handling: deployment vs developmentmode

2007-03-29 Thread Apaar Trivedi


It appears that the patch is only for versions 1.3 and 2.0, and we are
using 1.2.4, hence it won't apply correctly.

The failure handler you mentioned works quite well, thank you for that,
but it only seems to work in development mode.  Basically here is what
is happening for me:

In development mode, I can only handle my errors using the failure
handler
In deployment mode, I can only handle my errors using the re-direct to
the error page via RequestCycle.

What I would like is to be able to use both in either mode in Wicket
1.2.4.  Is this possible?

Thanks

 I understand that  if my app is in deployment  mode then all run

 request  will be  caught by  my RequestCycle.onRuntimeException,
 and this is working fine.  But how can I replicate this behavior
 during  development  mode?   During  development  mode  my  ajax

 not forward to the error page.

This is fixed already, see:

Use standard exception handling in AjaxRequestTarget
http://issues.apache.org/jira/browse/WICKET-313

However I didn't notice  different behavior between deployment and
development when I had this problem.

 Also, how  can I conceivably  handle these errors on  the client
 side, say for instance I experience an ajax runtime error during
 some request and  I would like to display a  friendly message in
 my window, instead of forwarding to the error page, how can this
 be done?

Just define wicketGlobalFailureHandler() JS function in your document.

Re: [Wicket-user] Binding and validating domain objects

 One problem I have due to avoiding DTOs is that most of the time I don't
 want to serialize my form models, because they are (often big) entities with
 lazy loaded associations. So in principle I would use an
 LoadableDetachableModel to load the entity from the repository each time the
 model is reattached. But suppose I'm updating a UserProfile. The first time
 it would be ok to populate the model from the persistent profile to be
 updated. But once the form is submitted there's no point in loading the
 profile from the repository again because its properties would be
 overwritten from those coming from the form anyway. So I'm tempted to
 subclass AbstractDetachableModel so that it loads the profile from the
 repository upon creation, but instantiates a brand new profile to be
 populated from the form upon reattachment. Is there a better pattern for
 this? Anyone has run into the same problem?

Sounds like that could work. Btw, you can still just use
LoadableDetachableModels. Something like this?

class SomeModel extends LoadableDetachableModel {

  protected Object load() {
return new Foo();
  }
}

new SomeModel(anotherFooThatWasLoaded);

The thing I want to point out here is that you can just initialize the
LDM with the object you loaded from the database, for the first
request, and then implement load like this to get fresh instances on
next requests.

Re: [Wicket-user] Radio.getValue?

 Ok, let me try to explain another way.

 If you create a page where you use the radio component. The radios represent 
 various kinds of datasets(OLAP cubes in this case but it does not really 
 matter).

 On monday the 1. march you record with jmeter your test case(jmeter only 
 records the http requests). In your test case you must select the retirement 
 dataset (which has the value radio5 on the html page).

 Some time has passed now and you want to run your jmeter test, but on your 
 page some of the datasets has been removed (they wasnt needed or was not 
 allowed to be shown). So now the page no longer contains the radio with the 
 value radio5, and your jmeter test will fail because wicket cant find the 
 radio(another error scenario would be if the radios changed order).

 So if radio component allowed the use of Ichoicerenderer, it could generate 
 the value based on the id of the ichoicerenderer for the particular dataitem. 
 This would bring better persistance to the radios. At least when testing with 
 jmeter.

 Did I do a better job explaining?:)

I think I got ya :)

 Some could argue that it's not issue, but it would be very handy to have the 
 ability to use the ichoicerender with every component that makes use of the 
 value attribute in inputs(havent thought it through though). Because it would 
 make it easier to use tools as jmeter.

It would also use a bit more memory and make it's API bigger and thus
more complex I'm afraid. I'm not sure whether it is a good feature to
build in by default. An alternative could be to enable users to
provide their own implementation, i.e. by making getValue non-final.

Looking at that code, I don't understand why we even need:
private short uuid = -1;

as there is no code other than in getValue that changes the value, and
that value can just be recreated everytime it is needed (as it is
nothing more than a call to getPage().getAutoIndex()). Am I missing
something here?

WDYT?

yes, you are missing the fact that getautoindex() increments the index on
every call that is why we cache it in the uuid var.

WDYT?


personally i dont like making getvalue non-final. this will patch this
component for this kind of testing, but what about other components that do
not have a stable name? are we going to have to start opening implementation
details on all of them just because users want to test it with something
static like httpunit? just my 2c.

Re: [Wicket-user] Binding and validating domain objects



class SomeModel extends LoadableDetachableModel {

  protected Object load() {
return new Foo();
  }
}

new SomeModel(anotherFooThatWasLoaded);



Oh, cute! Or even:

 new LoadableDetachableModel(anotherFooThatWasLoaded) {
   protected Object load() {  return new Foo(); }
 }

I thought that load would be called even the first time.

Regarding validation, I'm feeling a tad too frustrated trying to integrate
the bean validation framework infrastructure.

The problem is that spring validators assume that the bean is already bound.
But in the cases where the bean comes from the repositories (inside a
session-in-view), at the time it has been invalidly bound only an exception
thrown inside a transactional context (for example a @Transactional
annotated service method) could avoid persisting an invalid bean.

So I could make onSubmit transactional itself resorting to some aop arcane,
or I could put the validation inside a service (but then I would face a
nightmare of errors/exceptions mapping), or I could get rid of my beloved
validators and learn to love wicket validators (which are fine except that I
don't like the tight tie that they have with the presentation components). I
could momentarily detach the entity before binding it also, but this is a
nono for entities with complex lazy-loaded associations.

This is the kind of dilemma that I usually solve up not going against the
framework (wicket in this case). But if someone has an idea about how
validation could happen after binding inside a [EMAIL PROTECTED] context
without incurring the risk of persisting an invalid entity, and without
losing the ability to simply map errors to ui components, please let me
know.

Cheers,
Carlos

Re: [Wicket-user] Binding and validating domain objects


and if a user just refreshes the page? or you use it as a response

page somewhere else? then suddenly everything is empty?



If the user refreshes the page the previous request parameters will be
reposted and will overwrite the fresh form model object properties, so he
will see the page as was before his last non-submitted changes. That seems
fine to me. What I'm not sure is about what will happen if the first page
(the one previous to any submission) is reloaded. Will wicket reinstantiate
the form so the contents will be correctly reloaded from the repository? Or
will it reuse the form stored in the session whose model will now return a
blank object?

Cheers,
Carlos

  One problem I have due to avoiding DTOs is that most of the time I
don't
  want to serialize my form models, because they are (often big)
entities
 with
  lazy loaded associations. So in principle I would use an
  LoadableDetachableModel to load the entity from the repository each
time
 the
  model is reattached. But suppose I'm updating a UserProfile. The first
 time
  it would be ok to populate the model from the persistent profile to be
  updated. But once the form is submitted there's no point in loading
the
  profile from the repository again because its properties would be
  overwritten from those coming from the form anyway. So I'm tempted to
  subclass AbstractDetachableModel so that it loads the profile from the
  repository upon creation, but instantiates a brand new profile to be
  populated from the form upon reattachment. Is there a better pattern
for
  this? Anyone has run into the same problem?

 Sounds like that could work. Btw, you can still just use
 LoadableDetachableModels. Something like this?

 class SomeModel extends LoadableDetachableModel {

   protected Object load() {
 return new Foo();
   }
 }

 new SomeModel(anotherFooThatWasLoaded);

 The thing I want to point out here is that you can just initialize the
 LDM with the object you loaded from the database, for the first
 request, and then implement load like this to get fresh instances on
 next requests.

Re: [Wicket-user] nested DataView is not updating model

2007-03-29 Thread changdt2


this is what I have

public  class MyRadioChoice extends RadioChoice

public MyRadioChoice(final String id, final IModel model,List
choices)
{ super(id,model,choices);}
public boolean wantOnSelectionChangedNotifications(){return true;}
}

public void populateItem(final Item item) 
{

 QuestionModel questionModel = (QuestionModel)item.getModelObject();
 item.add(new MyRadioChoice(question,new
PropertyModel(question,question)),lisOfYesNo);

 ResultDataProvider rdp = new ResultDataProvider(); 
 MyResultDVO rdvo = new MyResultDVO();

rdvo.setResultDVO(questionModel.getSubQuestionModels());
rdp.setResultDVO(rdvo);


 DataView dataView = new DataView(CommonConstants.FOLLOWUP_QUESTION ,
rdp)
 {

protected void populateItem(final Item item)
{
Question question = ((QuestionModel)obj).getQuestion();
TextFirld ft = new TextField(subQuestion, new
PropertyModel(question,question), type) 
ft.setRequired(true);
item.add(ft);

 item.add(dataView);

}

basically the model seems not attached.  I do not see the field high lighted

Only if the request was from a form and when you are not using the
render-to-buffer strategy.

Re: [Wicket-user] nested DataView is not updating model


if you use dataview in a form you have to set the proper itemreusestrategy
so dataview doesnt discard items and rebuild them on every request

see dataview.setitemreusestrategy and reuseifmodelsequalstartegy

Re: [Wicket-user] Binding and validating domain objects


Only if the request was from a form and when you are not using the
render-to-buffer strategy.


Sorry Eelco, would you be so kind as to explain this, I'm new to wicket and
still a bit ignorant of its internals.
I see two access points to the form page:
1) First time you enter the page.
2) Resubmissions due to validation errors.
I'm assuming (maybe incorrectly) that during (1) a new form instance will be
instantiated, so a new model will be created with it that will return a
model object from the repository. Then, during (2), form contents will be
posted and bound to a fresh model object which was created from the
deserialized LoadableDetachableModel. Under this assumptions I see no
problem regarding reloads of the page in state (1) or in state (2).
But maybe you mean that the model is instantiated when you create the page
(not the form) so there will be just one moment satisfying (1) during the
entire session. Sorry if this is all too obvious but take into account that
I'm coming from a different controller/action mindset where the session is
barely used.

Cheers,
Carlos

 If the user refreshes the page the previous request parameters will be

he
 will see the page as was before his last non-submitted changes.

Re: [Wicket-user] Binding and validating domain objects

if you do a submit and validation erros happening then no new pag is
created but the page is reused. but you dont have a problem then
because the form will have all the values posted.But if the user does
a refresh then in default wicket setting, you dont do a new post, one
a page request to the current page because we use redirect_after_post
(in a special wicket way)

Re: [Wicket-user] how to unselect a dropdownlist ?

Don't make the drop down choice required when a null value is valid.

Re: [Wicket-user] Binding and validating domain objects


You forget the redirect after post, or even when nothing is submitted.
First render of the page refresh...



I have been reading about the redirect after post pattern (of which I wasn't
aware) here
http://www.theserverside.com/tt/articles/article.tss?l=RedirectAfterPost and
now I understand your point.
Will wicket always work in this mode? Is this configurable?
Another thing that I asked before in this thread and of which I'm still not
sure is about page creation. When will pages be created? Every time they are
accessed or just the first and then serialized into the session? This is
relevant to form model management because if my model discriminates between
the first time the form is entered and other times (for example after
resubmission), things won't work as expected if the model is instantiated
just once along the entire session (instead of once every time I enter the
form page for a new, say UserProfile, update).

Cheers,
Carlos

   Sorry Eelco, would you be so kind as to explain this, I'm new to
wicket
 and

   I see two access points to the form page:
   1) First time you enter the page.
   2) Resubmissions due to validation errors.
   I'm assuming (maybe incorrectly) that during (1) a new form instance
 will be
   instantiated, so a new model will be created with it that will
return a
   model object from the repository. Then, during (2), form contents
will
 be
   posted and bound to a fresh model object which was created from the
   deserialized LoadableDetachableModel. Under this assumptions I see
no
   problem regarding reloads of the page in state (1) or in state (2).
   But maybe you mean that the model is instantiated when you create
the
 page
   (not the form) so there will be just one moment satisfying (1)
during
 the
   entire session. Sorry if this is all too obvious but take into

 that
   I'm coming from a different controller/action mindset where the
session
 is
   barely used.

Re: [Wicket-user] Binding and validating domain objects

yess the rendering strategy is configurable. But do you really want to
resubmit always?   i already told you when a page is created or
reused. Its .created once (bookmarkable or by your sellf
setResponsePage(ne MyPage());) then with a form submit it will reuse
that instance from the session

It is configurable. Read up in IRequestCycleSettings#RenderStrategy
(ONE_PASS_RENDER, REDIRECT_TO_RENDER or the default
REDIRECT_TO_BUFFER).

 Another thing that I asked before in this thread and of which I'm still not
 sure is about page creation. When will pages be created? Every time they are
 accessed or just the first and then serialized into the session?

Bookmarkable pages accessed by their bookmarkable URLs will be created
every time. Everything else is created when you do, and then kept in
memory for later use. Depending on the session store (ISessionStore)
implementation you are using, they may be serialized only to be
de-serialized when users push the back button and the version they
want cannot be found anymore in memory. Otherwise, just the instance
as you put it there will be used. Note 'detachement' though.
Components and models are detached at the end of requests to enable
you to clean up temporary state and possibly optimize the ammount of
memory that is needed for the long term.

 This is
 relevant to form model management because if my model discriminates between
 the first time the form is entered and other times (for example after
 resubmission), things won't work as expected if the model is instantiated
 just once along the entire session (instead of once every time I enter the
 form page for a new, say UserProfile, update).

So, you cannot depend on the model being created on every request.
However, you can depend on your model being detached on the end of a
request, and if you combine that with lazily attaching like
LoadableDetachableModel does (easy to implement yourself too), you can
achieve the same thing as if you would have the models recreated on
every request.

Read: http://cwiki.apache.org/WICKET/render-strategies.html

 Another thing that I asked before in this thread and of which I'm still not
 sure is about page creation. When will pages be created?

A page is created when:
 - you do new MyPage()
 - someone requests a bookmarkable url (a link, the homepage, refresh
of such a page)

All subsequent requests will retrieve that page (and version) from the
page store (can be the session, filesystem, database), and work on
that instance.

[Wicket-user] XSD / Validation

2007-03-29 Thread Johannes Schneider


Hi,

I am new to Wicket and want to use XHTML and validate the files. I use 
IntelliJ Idea but I could not succeed in validating. I run into two 
problems:
- I did not find any wicket.xsd? I just found a DTD, but I don't know 
how I should use it.
- How can I switch the file extension to xhtml (at the moment Wicket 
only searches for .html). This would allow me to easily set up 
IntelliJ to validate only the *.xhtml files.



Thanks for your help.

Johannes Schneider
