[Wicket-user] localization problem
I'm developing a localized web application, where the use can change the language he wants the content to be displayed. However, if the localized message doesn't exist in the currently locale file (e.g. file.ro_RO.properties) wicket will not fall back to the default localized message which is in a 'file.properties' file. Is this the desired behavior or I may be missing something ? --- This SF.Net email is sponsored by the JBoss Inc. Get Certified Today Register for a JBoss Training Course.

[Wicket-user] Re: ComponentFeedbackMessageFilter
Does anyone know if it is at least possible to make a custom
FeedbackPanel which displays messages only for a specific component?
I want to make an extended FeedbackPanel which only shows messages for
Component fc.
See code below. But when I display my panel I see the feedbackmessages
for ALL of the components that are invalid.
I checked the toString() for fc:
[MarkupContainer [Component id = integerProperty, page = No Page,
path = inputForm:integerProperty.RequiredTextField]]
which I think means it's the required textfield
Does anyone know what I am doing wrong?
public class FXTooltipFeedbackPanel extends FeedbackPanel
{
/** The message filter for this indicator component */
private ComponentFeedbackMessageFilter filter;
/**
* @param id Component id
* @param fc formcomponent to display messages for
*/
public FXTooltipFeedbackPanel(String id, FormComponent fc)
{
super(id);
filter = new ComponentFeedbackMessageFilter(fc);
}
/**
* @return Let subclass specify some other filter
*/
protected IFeedbackMessageFilter getFeedbackMessageFilter()
{
return filter;
}
protected String getCSSClass(FeedbackMessage message)
{
return feedbackTooltipERROR;
}
}

Re: [Wicket-user] There must be some docs somewhere?
Yeah, partially you are just seeing my frustration at the framework evaluation process. I know struts backwards and forwards, but the deficiencies of that framework are all too well known. The same goes for webwork. I really want to use a component based framework, but echo/echo2 just doesn't have enough community support/active developers, and it has issues with maintaining too much state between requests. Tapestry puts too much logic in the templates and has an obnoxious syntax for the template logic. However, it is a mature product with solid docs and even a book or two written about it, not to mention the support of the jakarta universe. Even rumour I've heard about wicket screams to me that it is the framework I want, but every time I try to dig in, i find it incredibly frustrating. Generally, I'm as good at picking up new technology, especially web development technology, as any developer I've come across, so if I'm having this much trouble getting up to speed with wicket, then what about the rest of my team once they have to begin trying to write code. Simple apps from the examples are easy enough, but the complexity of the examples gets exponentially incomprehensible as the sophistication of the app increases, often making great big leaps of complexity between one exmaple and the next. We don't have the luxury of adding sophistication incrementally, so we have to be able to maximize the value of the framework almost immediately, and that is very difficult given the current state of the docs. Browsing javadocs, hoping that the name of the class that provides the functionality I'm looking for will be sufficiently obvious to jump out at me doesn't really cut it when there is a team of 12 developers being held up while we guess as to a solution. The more I explore, the more I want to use wicket, but the less I think I can actually afford to. My only option is to assume that I can come up to speed fast enough to stay one step ahead of my team, writing the relevant docs and style guidelines before they need them, but I don't have any confidence I'll be able to do so. That leaves me looking at Tapestry (or some model 2 framework, god forbid), which I find very frustrating. In short, first impressions count for a lot in the kind of analysis I'm trying to perform, and Wicket does not yet cut the mustard on that score. It reminds me of Zope, circa mid 1999. Super easy to do the simplest things, but add a little sophistication, and you'd better know exactly how everything works internally or it'll be like beating your head against a wall. Should I wind up using it (currently, I doubt it), I'll be sure to submit any docs I write back to the various projects. --sam On 11/16/05, Eelco Hillenius [EMAIL PROTECTED] wrote: Yeah, the fact that is tells you to check out the wicket-stuff module is bad.

the code which uses the proxy trys to catch an Exception thrown by the

I was just thinking of an easy way to configure the static instance
gotten
from SpringInjector.getInstance(). So I thought that
SpringInjector.getInstance() would call
ApplicationContext.getBean(SpringInjector,SpringInjector.class) and if
there is none return the singelton instance.
but then you have to make the bean name configurable, what if someone has
two injectors or wants a different name. it will never end. creating a
custom one is trivial because the base class is very simple. a few lines
of
code later you can have one that works great for you.
An alternative could be that there is a generic injector which loads a
list of IFieldValueFactories from the WebApplication.
once again, i think this is better done in a custom way. its very easy to
have something like this:
class InjectorLocator { public static Injector getInjector() { // create
and
return injector here } }
then instead of using springwebpage create your own that uses the static
lookup from injectorlocator to get the injector as opposed to using the
default springinjector. this can even allow you to do unit testing on
your
pages, just have some flag in getInjector() that returns a noop
implementation.

Re: [Wicket-user] There must be some docs somewhere?
But how do we know what kind of documentation to write when we don't know what you are looking for? Component reference is there. Wiki contains several good docs on the inner workings, spring, hibernate, creating custom components. If you and other users to be don't ask for specific documentation, how should we be able to provide you with what you need/want? Just saying: there is no documentation, or not enough doesn't cut it. So, please, tell us before you either leave us, or before you know Wicket too good, what do you need, what are you looking for?

Re: [Wicket-user] Re: ComponentFeedbackMessageFilter
Well, it's little more complicated. FeedbackPanel doesn't use the filter
directly. It uses FeedbackMessagesModel to feed the ListView, and that
model uses the Filter.
Nevertheless, overriding getFeedbackMessageFilter worked well for me.
Which version of wicket are you using? I'm using 1.1 and I'm having no
problems with it.

Re: [Wicket-user] Preserve form state
Well, having to do validation in model seems like a step backwards from
what I have now. There are already validators that can be attached to
objects, no to mention, that I would have issues with feedback, etc.
I still don't think layered model is a way to go. Currently, I have a
solution, that works well form me. But it has two drawbacks.
1. It's really hacky.
2. It uses the invalidInput property of form components to store
temporary values. When clicking on an ImmediateButton, all form
components are marked invalid (so that they remember the values in
invalidInput) and all feedbackMessages are supressed. So after clicking
immediateButton, all feedback messages are hidden (even the valid one).
The advantages are that validation works as usual.
I'm attaching the source code in case anyone needs this. It seems that
this behavior (not implementation) won't have enough support to get into
wicket.
-Matej
Johan Compagner wrote:
first of all we are talking about 2 problems here!
Matej's and Laurent problems are completely different.
I still believe that Matej should use a temp model (in between model)
And the validations shouldn't be on the component level but between the
between model and the real (strong typed) model.
I really believe this is the best way. Any thing i can currently think
of will result in something like that anyway.. The values Need to be
stored somewhere!!
So having something like a model:
Model(Model realModel)
{
Hashmap values;
getObject(Component comp) return values.get(comp);
setObject(Component comp, Object value) values.put(comp, value);
public void saveToReal()
{
Object realObject = realModel.getObject(null);
while( Iterate over the values maps keys)
Component key;
String stringValue;
Object value = converter.convertToType(stringValue);
validator.validate(key,value)
String id = key.getId() // or get some kind of binding
see BoundedCompoundPropertyModel
Objects.setValue(id,realObject,value,null);
}
}
this is just a rought idea how a in between model should or could work.
Laurents problem is completely different, He doesn't want to hold the
data (and do nothing with it) over multiply pages.
He just wants portions to be validated and portions to be kept for one
request only but not validated.
I think this is now already possible with the
Button.defaultFormProcessing boolean
Then the buttons must have a list of components which he must be
validated before he does process everything.
then he can call FormComponent.validate() and if that goes ok
FormComponent.updateModel() (and so on on the complete List)
I think we are then where we are. You just need a special button that
has a list of FormComponents to be validated...

I don't think it's a good thing storing the temporary values in
model
(at least in my case), because model is typed. The temporary values
should only be strings (get from Http request).

Tnx for clariffying that, im using the CVS version currently, but I

is there any example which uses this, or a simple peice of code example

Re: [Wicket-user] Preserve form state
Thanks a lot for having sent the source code. I'll check it ASAP (but not before next week, I fear), because I'm *very* interested in encapsulating the behaviour you're talking about in a reusable package. I already have some ideas under the cover, but I'm far to having good knowledges of Wicket internals, and I guess your code will help me delve into those internals. In short, my idea, if feasible, would be to create a kind of SmartForm that could be a border around other FormComponents, and even embed other SmartForms. And a SmartForm validation will be bound to a set of Buttons/Actions explicitly added to the SmartForm using something like SmartForm.validateOnButton/Action(Button/Action). And you could also cascade validation : if a SmartForm b is embedded in another SmartForm a, you can choose on the SmartForm b if validation of the parent SmartForm (a) will cascade the validation to the SmartForm b. So you then have a SmartForm b, attached to a validation button bButton, and the SmartForm a, attached to a validation button aButton If b declares that validations cascade through it, then the following use cases will be as follows : - user presses bButton : only the validations of the b SmartForm are done (and also updates of the b models). The values entered by the user on the other formComponents of the a SmartForm are preserved (and here your code is of some interest to me). - user presses aButton : the validation occurs on all the formComponents inside the a SmartForm, and also on all the SmartForms that accept validation cascading, so formComponents of b SmartForm are also validated. Another interesting use case that is solved by this solution is the use case where in the same form you have some formComponents needed for the creation of something, and associated to a Create Button, and some other formComponents that display the contents of (editable) already created somethings (for bulk updates). Then you create 2 SmartForms : one SmartForm (lets call it createForm) for the formComponents needed when the user hits the Create Button (that then *need* to be validated), and one SmartForm for the formComponents of the rest of the page (lets call it updateForm, and say that it's bound to the global submit button of the page). And to end the settings of your components, you call some createForm.setCascadeValidation(false). Then when the global submit button of the page is called on the global updateForm, if the createForm is embedded in the updateForm, then validation will not occur on the createForm SmartForm (and that's good !). A last interesting use case for this : in all the pages of you application, you have a little box that allows the user to sign in. A user hits a page where he can enter some values in some fields. And before validating the page, he decides to log in. What I want is that after having logged in, the page still presents the values entered in its body by the user. So the need to : - have a single form for all the data of the page - use a concept like my SmartForm in order to separate the formComponents dedicated to the user login action (presumably login/password :-) from the formComponents of the main purpose of the page at hand (some blog entry formComponents, ... whatever ...). Without the use of a concept like SmartForms and changes in Components as those mentioned by Matej, it will be very difficult, verbose, and error prone to have this *simple* and *basic* (user friendly centered) behaviour on all the pages of an application ... But yet, it is still all in my head, I have nothing to present yet (but I hope it will come soon).

Re: [Wicket-user] Preserve form state
Okay, so if I understand you correctly, you suggest changing default
form processing like this?
- immediate button submitted:
validate();
if (hasError(); {
markFormComponentsInvalid();
onError();
}
updateFormComponentsFakeModel();
// this is executed even if form has Error. But the model of all
// components has to be a special two layer model and must know
// whether to update the real model or only the fake model.
This seems doable, the little complication I'm aware of is to ensure
that all form components are having this special model.
Another thing is that maybe two kind of model wrappers will be needed.
One implementing ICompoundModel and one not. I'm not quite sure here.
Say you have a form and set it's model to something like
DoubleLayerCompoundModelWrapper. (it's a wrapper implementing
ICompoundModel).
All form components will inherit it. So far, so good. But if I have a
form component with it's own model (say PropertyModel), could I just
wrap the model with DoubleLayerCompoundModelWrapper too, even if it's
not compound model?

Re: [Wicket-user] Preserve form state
why use a non default process button? (immediate?)
If you have a in between model then all youre buttons can just be normal once that just doe simple validation (or non)
to the in between model
Then have one (or more) buttons that knows about that in between model
And if that button is pressed it calls a method like processModel() on the inbetween model
Then that model will do the real validation and pushes data to the real model (just like form does now)
All feedback can still be set then if something goes wrong. I don't see a problem doing that or do i miss something?
I still think that this is for youre specific case a pretty clean solution. But maybe i am missing something.

I still believe that Matej should use a temp model (in between model) And the validations shouldn't be on the component level but between the between model and the real (strong typed) model.
I really believe this is the best way. Any thing i can currently think of will result in something like that anyway.. The values Need to be stored somewhere!!
So having something like a model: Model(Model realModel) { Hashmap values;
getObject(Component comp)return values.get(comp);
setObject(Component comp, Object value) values.put(comp, value);public void saveToReal(){
Object realObject = realModel.getObject(null);
while( Iterate over the values maps keys)
Component key;
String stringValue;
Object value = converter.convertToType(stringValue);
validator.validate(key,value)
String id = key.getId() // or get some kind of binding see BoundedCompoundPropertyModel
Objects.setValue(id,realObject,value,null);} } this is just a rought idea how a in between model should or could work.
Laurents problem is completely different, He doesn't want to hold the data (and do nothing with it) over multiply pages. He just wants portions to be validated and portions to be kept
for one request only but not validated. I think this is now already possible with the Button.defaultFormProcessing boolean Then the buttons must have a list of components which he must be
validated before he does process everything. then he can call FormComponent.validate() and if that goes ok FormComponent.updateModel() (and so on on the complete List)
I think we are then where we are. You just need a special button that has a list of FormComponents to be

Martijn Dashorst wrote: But how do we know what kind of documentation to write when we don't know what you are looking for? I think part of the problem is that the documentation is not as easily found as I for one would like. For instance, from the front page of the Wicket site, if I want to find the New User's Guide, I would have to look at the Documentation section and decide that since nothing else looks likely, I'll check out the Wiki. There, in the documentation section, I'll find a link to the (quite incomplete) guide. As a new user, I don't care that the documentation is maintained in a wiki, and I might not want to go hunting through a wiki to find what I want. So just choosing to click that link is a leap of faith. Had there been a link from the front page to the New User's Guide, I wouldn't have hesitated to go to it. Similarly, for quite some time, even though I'd looked at the wicket-examples often, I'd always gone in looking for something specific, and never even noticed that there was a good Component Reference. Once again, if this were linked to from the home page, it would be much quicker to find. Or take the whole CVS issue. We all know that Sourceforge's CVS can get very annoying. I've been able to download the wicket-contrib modules that I know about, but I've never been able to get a comprehensive list of such modules. SF always tells me that the list is not available, but I've never found the whole list. Eelco's message in this thread is the longest list I've seen, and I doubt it's complete. What I would prefer would be a Documentation page linked off the front page which contains and organizes links to all the known resources. But for now, the documentation menu lists only Vision, FAQ, Javadoc, Wiki, and Dependencies. Plus there is the getting started menu, which has Examples and Download. The FAQ is minimal (which might be a good thing.) Vision is interesting, but doesn't tell me anything about *how* to do anything. Javadoc is great once you're going, but isn't usually helpful in getting going. The examples are good, but there aren't many. One specific example of my own process is that I needed to have a class with some markup and child classes with their own embedded markup. I didn't exactly want a border or a panel. It was only because I'd been reading this list and seen the phrase markup inheritance that I knew what to look for, and even then I found it with Google and not from any of the obvious documentation sources. I eventually found my way with Google and this mailing list, but the process might have been much quicker if the New User's Guide were more complete, and if these other resources were easier to find. I'm hoping in the next several weeks to be able to contribute a little to these, but I am still too far from being an expert to be very sure of myself in any of this. -- Scott --- This SF.Net email is sponsored by the JBoss Inc.

Re: [Wicket-user] Preserve form state
Because I want form components to do the validation, not the model.
I want the form code to be as close to an ordinary wicket form as
possible. That means that components themselves do the validation, not
the model.
If I used the default process button, the action (like showing Choose
screen) wouldn't be executed unless all entered data is valid.
It seems that I will play a little with the idea of double layer models
and see, if it's better than my current solution.

Johan Compagner wrote:
why use a non default process button? (immediate?)
If you have a in between model then all youre buttons can just be normal
once that just doe simple validation (or non)
to the in between model
Then have one (or more) buttons that knows about that in between model
And if that button is pressed it calls a method like processModel() on
the inbetween model
Then that model will do the real validation and pushes data to the real
model (just like form does now)
All feedback can still be set then if something goes wrong. I don't see
a problem doing that or do i miss something?
I still think that this is for youre specific case a pretty clean
solution. But maybe i am missing something.

Okay, so if I understand you correctly, you suggest changing default
form processing like this?
- immediate button submitted:
validate();
if (hasError(); {
markFormComponentsInvalid();
onError();

updateFormComponentsFakeModel();
// this is executed even if form has Error. But the model of all

This seems doable, the little complication I'm aware of is to ensure
that all form components are having this special model.
Another thing is that maybe two kind of model wrappers will be needed.
One implementing ICompoundModel and one not. I'm not quite sure here.
Say you have a form and set it's model to something like
DoubleLayerCompoundModelWrapper. (it's a wrapper implementing
ICompoundModel).
All form components will inherit it. So far, so good. But if I have a
form component with it's own model (say PropertyModel), could I just
wrap the model with DoubleLayerCompoundModelWrapper too, even if it's
not compound model?

custom one is trivial because the base class is very simple. a few lines of code later you can have one that works great for you. An alternative could be that there is a generic injector which loads a

Certainly, it is an attempt to generalize this solution. But you're

I'll try to code some things and then come back to the list with it.
I would like to be able to have such functionality by coding this as a
SmartForm user:
MyPage.html
form wicket:id=globalForm ..
!-- Login logical form --
span wicket:id=loginForm
input type=text wicket:id=login/
input type=password wicket:id=password/
...
input type=button wicket:id=loginButton/
/span
!-- Search logical form --

input type=text wicket:id=searchCriteria/
input type=button wicket:id=searchButton/
/span
!-- Main body logical form --
input type=text wicket:id=globalField/
...
input type=button wicket:id=globalButton/
/form
MyPage.java
MyPage() {
SmartForm globalForm = new SmartForm(globalForm);
add(globalForm);
SmartForm loginForm = new SmartForm(loginForm);
add(loginForm);
SmartForm searchForm = new SmartForm(searchForm);
add(searchForm);
// ... form configuration as usual, maybe use a CompoundPropertyModel ...
loginForm.add(new TextField(login));
loginForm.add(new TextField(password));
loginForm.add(new Button(loginButton, Log In));
// Indicate that the loginForm will not participate in the Global
Form validation process
// So just the loginButton will have a validation/model update
action on the loginForm
loginForm.setPropagateValidation(false);
// ... same for search Form
searchForm.add(new TextField(searchCriteria));
searchForm.add(new Button(searchButton), Search);
// SearchForm do not participate in global validation
searchForm.setPropagateValidation(false);
// Main page form
globalForm.add(new TextField(globalField));
...
globalForm.add(new Button(globalButton, Submit page entries);
}
This would allow great validation units of work power, while keeping
it as simple as it is now for common use cases.
What do you think about it ?

Re: [Wicket-user] Wicket for tapestry users
A lot of tbd :) I think if you want to compare, there's nothing that beats taking a look at code. Wicket has e.g. a hangman example and a component reference (part of wicket-examples); if you take a look at that code, and maybe try something yourself, you should get a fairly good idea. Some of the main differences: * Wicket is not a managed framework. That means that you - the programmer - are in charge of component creation yourself. You do this with javacode opposed to doing it declarative. Pro: gives you flexibility/ you wont be limited by what the framework builders thought up/ you don't have to learn how the framework manages and how the declaring language (xml) works. Con: harder to integrate with other frameworks somethimes/ wicket internals sometimes difficult. * (like Igor said) Wicket purposefuly does not support scripting like features in your markup. Pro: everything stays very clean and it is easier to guess how things should be done. Con: harder for people that are used to a 'php/jsp way of doing things' and you need programmers that at least understand the basics of OO Java programming. Pro: clarity and cleaneness. Con: some things are more work with Wicket and you have to keep your java component tree in sync with the markup nesting. * With Wicket every component is truly stateful. Every property you define is part of it's state, and there is a flexible undo mechanism you can use to support any advanced backbutton support you might want. No need for a rewind mechanism. Furthermore, wicket component can be nested and can take part of any collaboration you want in the same fashion you could do in e.g. Swing. Pro: flexibility and very easy to do complex things if you know your Java. Con: sometimes easy to end up with unoptimized spaghetti like code if you take too many short cuts (much like you could have with Swing). * Creating custom components with Wicket is super easy. Just extend from an existing one (or from base class WebComponent or WebMarkupContainer), make it available in your classpath and your done. There's no extra configuration (libraries) and magical strings (ids) involved. For advanced component initialization, you can use IInitializer.

[Wicket-user] performance problem - urgent
Hi all, I've deployed my first application with wicket. However, I have a BIG annoying performance problem with it, and it is visible just in production. We have a pretty big picture on the top of the page, a 200k gif, which is LOADED again and again on every page, it's not cached. On every other sites we've developed, even the big pictures after they were loaded and cached first, they work fine, they are not downloaded every time. In this case, it seems that all the pictures are downloaded every time. The site in case is: http://www.ceramicamaria.ro/ just in case you want to check it live. As you will see, the experience is lousy as you need to wait tons of time for each page loading Anybody has a clue why this is happening ? Any suggestions are greatly appreciated, I assure you.

Re: [Wicket-user] Preserve form state
do you really want that seperating also in the html?
(with all those spans?)
Looking at youre example and guessing what the smartform (and the button in it does)
IT is the same, the smart form is just the holder of the components just as i said my List object inside a button would be.
It is just a bit different composition of things.
I do see something in this (don't know how manu people would really use this but it would be nice)
What i don't like is that you also has to specify it in html. I would like to do that pure in java.
(so a smart form is not a Wicket component)

On every other sites we've developed, even the big pictures after they were loaded and cached first, they work fine, they are not downloaded every time. In this case, it seems that all the pictures are downloaded every time. The site in case is: http://www.ceramicamaria.ro/ just in case you want to check it live. As you will see, the experience is lousy as you need to wait tons of time for each page loading Anybody has a clue why this is happening ? Any suggestions are greatly appreciated, I assure you.

Re: [Wicket-user] performance problem - urgent
But you don't have the wicket servlet mapped to the images url, so it has no way to affect the images. Another thing that comes to my mind is that maybe you have a servlet filter that can cause this, but it doesn't seem probable to me. Could you send your web.xml? -Matej Dorel Vaida wrote: Dorel Vaida wrote: Matej Knopp wrote: Hi. Wicket is hardly responsible for the headers, that come with your (static) images.

Re: [Wicket-user] performance problem - urgent
The image is served by the http server (apache), but is seems to be obtained through tomcat connector, so it's provided by tomcat. Neverthelles, the result is, that for some reason, the image lacks the Last-Modified http header. Therefore the browser always checks and downloads it, because it doesn't know that the image hasn't changed. -Matej Alexandru Popescu wrote: #: Matej Knopp changed the world a bit at a time by saying on 11/17/2005 8:28 PM :# No, he is not using resource reference.

Re: [Wicket-user] There must be some docs somewhere?
OK, I'll try to be more helpful in my criticism... Having finally found wicket-stuff, I was able to spend some time looking at the code that addresses my needs (hibernate integration most specifically), and I'm feeling a little more comfortable. More importantly, I'm going to have to write sample/framework code and documentation for my team in order to bring them up to speed. If I do so, I will certainly be contributing them back to be integrated into the documentation in some way. Off the top of my head, here are some of the things I would like to see: A suite of examples that build upon each other in gradual steps, introducing concepts in a logical order in order to build an increasingly complex application in an attempt to reduce the slope of the learning curve. Ideally, the final examples should be a fairly usable application, using all the functionality available and demonstrating best practices. That's basically the structure of the ... in Action books from Manning, whgch has always worked well for me. Not trivial to generate, of course, but it seems like whoever does would be a srong candidate for authorship of WIcket in Action which is a nice resume bullet point. The widespread use of anonymous classes in all of the example code make life needlessly difficult for newcomers. I'm still having trouble understanding how and when some of the model objects get updated, although the wicket-stuff code started to clear some of that up. Personally, I think the use of anonymous classes should be saved until after a reasonable understanding of the functionality has been achieved. Database integration is fundamental to the vast majority of web applications, and yet it is totally unaddressed by the current documentation. I kept finding reference to tight integration with Hibernate, but could never find examples or even a description of it. That stuff should be put front and center in the core docs. It was the piece I started looking for first, in order to evaluate wicket, and I was unable to find it for days. The nice thing is that if examples use a fairly generic DAO abstraction, it should be possible to provide nice examples that aren't dependant upon any particular suite of technologies. Just describe the DAO interface and then use those them to access standard POJOs. Obviously, most folks will probably be doing a Hibernate/Spring thing, so addressing best practices for combin ing those technologies with Wicket is enormously valuable, but it should be secondary to providing generic best practices for dealing with DAO access, detachability, etc. One of the issues I'm still having is that I know nothing about Spring. Since every example I've found uses Spring inversion of control, they can be difficult to comprehend the flow. By using a generic DAO interface, it would be easier to understand the relevant wicket concepts, and I could then separate hibernate from spring and wicket. Another fundamental change - make sure ALL of the examples are listed on the website, even if they don't all have nice descriptive documents. I read through the examples on the home page (hellow world, navomatic, guestbook, and stockquote), and assumed that that was all that was available from the examples. I didn't happen to click on the link to see the wicket-examples in live action, which would have exposed all the other available examples, including the all important component reference. There is no direct link to the component reference from the wicket home page. You have to click on a link describe merely as 'live action' versions of the examples listed on the same page, in order to discover it. In my case, I didn't discover it until I installed the wicket-examples into my own container and pointed my browser at it. The descriptive documentation for wicket-stuff really needs to be improved. I hate to say it, but I'm pretty old school. I edit my java code in vi in a terminal window. I use CVS from the command line. I compile my projects with ant. I can't stand eclipse (it just eats up desktop real estate and forces me to use the mouse all the time). As such, randomly discovering that all of the instructions on the wicket-stuff website were incorrect is more than a little difficult and frustrating. Just cleaning up the instructinos and providing a decent description of what I can expect to fnd for my trouble would be REALLY handy. I still don't know what the wicket quickstart project is or does. I don't know use any of those IDEs and there is very little descriptive text. If I knew what it provided, I might motivate to install eclipse to check it out, but given the lack of usefulness of other examples and documentation, I figured it would be similar, so I never bothered to investigate that far, since it would have been a large PITA. Actually, I just watched the video and it doesn't provide any info about writing wicket code, beyond how to insert a label, which is covered by hello, world. So,

OK, now I have a first attempt to submit. It is what could be considered as a cleaner way to address Matej's initial problem.

It is too late tonight for me to explain what I did, so please for the moment take a look at the 2 new classes versions : wicket.markup.html.form.Form wicket.markup.html.form.FormComponent or the diffs files if you prefer. And I've joined 2 very basic test files (markup class) In short : in the new version, on formSubmitted(), child form components are told that a new user input is available (method FormComponent.newUserInputAvailable()). In this method, the FormComponent stores the user input in a rawInput field. This rawInput is then available for re-rendering for both use cases : when data is invalid and when model is not up to date (for example when returning from another page as in Matej's use case, the form will be rendered again with the rawInput, and not the model).

[The tradional example has been the pet shop, but nowadays, I think a blogging system is a nice worked example for a web framework.] I haven't had a chance to look at Igor, et al's new Spring integration, but here are a few bits of advice from my experiments with Wicket/Spring/Hibernate: - If you're using Spring to manage your DAOs, you don't need to look at wicket-contrib-hibernate. - Spring and Hiberate already integrate together really easily. Take a look at org.springframework.orm.hibernate3.LocalSessionFactoryBean. They should have plenty of examples, but if you need a more complete spring.xml, let me know and I'll send you one. - To map Hibernate sessions to requests, Spring AOP's OpenSessionInViewInterceptor makes everything automatic. Here's what I use: !-- The openSessionInViewInterceptor is for Wicket requests; the HibernateInterceptor is for business objects -- bean name=openSessionInViewInterceptor class=org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor property name=sessionFactoryref bean=sessionFactory//property property name=flushModeNamevalueFLUSH_AUTO/value/property /bean - For an example of Transaction Templates, take a look at http://blog.exis.com/colin/archives/2004/07/31/concise-transaction-definitions-spring-11/ - If you can get to the DAOs from your pages or models and your Sessions are managed correctly, using them with Wicket is very easy. - I'm not yet sure what the best practice for detatching is. If you have relatively small objects and plety of RAM, you could use hibernate's lock() function to attach to the current Hibernate session. Most likely, though, having your models keep the id of the object and loading them from the DAO maks the most sense. Good luck, Dan --- This SF.Net email is sponsored by the JBoss Inc.

Re: [Wicket-user] There must be some docs somewhere?
irt spring+hibernate+wicket: Dan is absolutely correct when he says that wicket should never touch hibernate directly. all the hibernate-related logic should stay inside spring and be exposed directly through a dao object or through a service facade. i think wicket-contrib-data and wicket-contrib-data-hibernate should be taken out of cvs as they do not display good programming practices in general. i thought Phil was going to do that, but i guess he never got around to it, are you reading Phil? take a look at wicket-phonebook in wicket-stuff, its an extremely simple crud application that uses the above technologies. it also has excellent javadoc thanks to Gwyn. irt general dao: if you are talking about pulling out data from the database to display, such dao already exists and is documented. look up: IDataProvider in wicket-extensions. it is used by the DataView component which is also in the extensions. to see a demo of these look in wicket-phonebook or wicket-examples - repeaters. the repeater examples build upon each other from a simple looping view to a fully database driven datatable component. irt spring integration: spring integration doesn't come easy with a framework like wicket. unlike servlets which are fairly static singletons wicket applications consist of a lot of volatile objects with varying life cycles. this makes keeping dependencies difficult especially because objects are often serialized. there are basically two approaches: simpler approach is to keep all your dependencies in wicket's singleton Application object and let everything else look up dependencies from there, the other approach is more sophisticated - it involves creating proxies for dependencies that can be serialized and retain enough information to be able to look up the dependency when they are deserialized (possibly in another vm). i recently wrote up an article on this in the wiki that describes the two ways: http://www.wicket-wiki.org.uk/wiki/index.php/Spring i haven't had much time to spend on it so its rough around the edges. people should feel free to fix it, it is a wiki after all. irt detaching: the whole idea of detaching objects is to reduce session state. if you have a pretty big object that you are using as a model, why keep it in session when you can only keep the id and load the object when it is fist accessed. if you are using the object as a model for the form, then you don't need to reattach/lock it, just use hibernate merge instead of saveorupdate. see wicket-phonebook for both use cases. irt trail tutorial: if someone can come up with a scope/spec for a small wicket+hibernate+spring application / trail breakdown i can put one together as long as other people promise to write documentation, some javadoc, and dress up the html templates. -Igor On 11/17/05, Dan Gould [EMAIL PROTECTED] wrote: Sam Gendler wrote:...

Re: [Wicket-user] There must be some docs somewhere?
Martijn and I are writing Wicket In Action currently. We're not using the gradual examples thing like e.g. Tapestry In Action has because we don't like it that much. Maybe Martijn more than me, but I thought such a book-wide example is too far fetched to be useful. Personally, I am much more charmed about 'Programming Ruby The Pragmatic Programmer's Guide' that has a lot of small but focussed examples. Anyway, if I had more time I would definitively want to write a more elaborate example like a blog. The cdapp example that you can find in wicket-contrib-examples is my try of an application with Hibernate CRUD and some extra's. Please check that one out too. Eelco A suite of examples that build upon each other in gradual steps, introducing concepts in a logical order in order to build an increasingly complex application in an attempt to reduce the slope of the learning curve. Ideally, the final examples should be a fairly usable application, using all the functionality available and demonstrating best practices. That's basically the structure of the ... in Action books from Manning, whgch has always worked well for me. Not trivial to generate, of course, but it seems like whoever does would be a srong candidate for authorship of WIcket in Action which is a nice resume bullet point. --- This SF.Net email is sponsored by the JBoss Inc.

Re: [Wicket-user] There must be some docs somewhere?
Oh, and one of the by products we plan for us writing Wicket In Action is a useable reference manual. Something that doesn't conflict our interests with Manning of course, but that serves as a good point of finding how to do things in Wicket. Re looking for support: I am currently thinking setting up a support company for Wicket. I would need it for several things, giving official Wicket support being one of them. If demand is large enough, such a company can be fact in a few months from now. Eelco On 11/17/05, Eelco Hillenius [EMAIL PROTECTED] wrote: Martijn and I are writing Wicket In Action currently.
