Re: form validation question
I'll throw in my endorsement for (1). Often, we programmers get too
wrapped up in try to use some clever framework feature for every
minute detail ... when sometimes, it's simpler just to write a few
lines of code.
A listener which first performs validation before processing is easy
to write, easy to read, and extremely flexible. I'm not saying it's
the best way to do everything; it's just an option people often
overlook.
Here's a more complete example:
@Bean( value=ValidationDelegate.class )
public abstract IValidationDelegate getValidation();
@Component(
type=TextField, id=email,
bindings = { value=email } )
public abstract TextField getEmailComponent();
public abstract String getEmail();
public abstract void setEmail(String value);
@Component(
type=TextField, id=password,
bindings = { value=password, hidden=true } )
public abstract TextField getPasswordComponent();
public abstract String getPassword();
public abstract void setPassword(String value);
public IPage logIn()
{
if(isBlank(getEmail()))
getValidation().record(
getEmailComponent(),
Please enter the email address for your account.);
if(!matchPassword(getEmail(), getPassword()))
getValidation().record(
getPasswordComponent(),
Sorry, this is the wrong password.);
if(getValidation().getHasErrors())
{
// take action to prevent commit if necessary
return this;
}
// --- Success ---
// ... do work ...
// ... commit work ...
return successPage;
}

You can either:
1) Do all the validation in your listener (on the Java side), or
2) Write your own client-side valdation code in JavaScript.
The server-side validation would look like this:
ValidationDelegate delegate = (ValidationDelegate)getComponent
(delegate);
if (!getCheckbox()) {
String firstName = getFirstName(); // @Text component bound to
firstName
if (firstName == null || firstName.length() == 0) {
delegate.setFormComponent((IFormComponent)getComponent

Listener delegating causes NullPointerException
The basic problem: one page's listener calls another page's listener
(after activating the other page). The other page records a
validation error, and that causes a NullPointerException deep in
Tapestry's guts.
The details:
I have two pages (Subscribe and SubscribeAlternateLink), both of
which involve the user entering/selecting a URL. Once the URL is
entered, they share the same logic -- and I want either one of them
to end up on the Subscribe page in case of an error.
So I have this page delegate its subscribe() listener to the other page:
public abstract class SubscribeAlternateLink extends MyBasePage {
...
public IPage subscribe(String url) {
Subscribe subscribePage = getPage(Subscribe.class);
subscribePage.setUrl(url);
getRequestCycle().activate(subscribePage);
return subscribePage.subscribe();
}
...
}
And the other page has a URL field, which will show the URL the user
entered, with an error:
public abstract class Subscribe
extends MyBasePage {
@Bean( value=ReaderValidation.class )
public abstract IValidationDelegate getFormValidation();
@Component(type=TextField, bindings = {
value=ognl:url,
validators=validators:required } )
public abstract TextField getUrlField();
public abstract String getUrl();
public abstract void setUrl(String url);
public IPage subscribe() {
if(getFormValidation().getHasErrors())
return this;
try {
// ... do subscription ...
} catch(SubscriptionException e) {
getFormValidation().record(getUrlField(),
e.getMessage()); // ***
return this;
}
// ... follow-up stuff ...
}
}
When submitting from the Subscribe page, errors get recorded fine.
When submitting from the SubscribeAlternateLink, I get an exception
on the line marked ***:
java.lang.NullPointerException: Parameter fieldName must not be
null.

It looks like the URL component on the Subscribe page isn't fully
initialized. Is this a bug? Or do I need to do something more to
initialize the Subscribe page?

Right. And just to be clear: the .xhtml is not necessary for XHTML, not just for Tapestry, but in *any* content -- and I don't think the text/xml mime type is necessary either.

However, when I do this, Tapestry gives a PageNotFoundException. It

Re: Google Web Toolkit
Horrible, horrible, GridBagLayout I loathe it. What an awful mess. CSS is so many thousands of times nicer for doing layout I am sympathetic to the applets not Javascript argument, though. Applets with CSS layout would be especially nice. But applets don't integrate well with the flow of the web: like Flash- based sites, you can't bookmark them, search engines can't index them, etc. There are limits to what they're good for. If there were a good way to attach Java to a page's DOM, then we'd be cooking. I wonder how limited GWT is in this respect? Tapestry works very hard to respect the client's control of their browser.

Re: Google Web Toolkit
I completely agree with about 90% of what Todd writes. This is definitely not a flash in the pan, and the idea of using an intermediate language (Java, in this case) that compiles to client- side code is a brilliant and revolutionary one. Finally, there was nothing wrong with the original MVCs. Swing (or any other traditional MVC) worked. Actually, I think Swing kind of sucks, and looked good when it came out only because MFC, X, and AWT were so much worse. Swing ain't no Cocoa. And honestly, I still kind of miss Metrowerks Powerplant. But my real concern about GWT is that it appears to bring us back to the world where everything is just a mess of one-size-fits-all widgets. Konstantin is right, of course -- there is no web text editor than can compare to a dedicated text editor rich GUI. The reason for that, however, is because people took a *lot* of time to work out all the minutiae of making a good UI for editing text. By contrast, most desktop apps stick their domain into existing widgets (one of which is a text editor) instead of going to the enormous trouble of build a new, highly specialized UI with custom graphics. DHTML+CSS is quite expressive, but much lower cost, than build a custom desktop UI component pixel by pixel. Right now, GWT seems to lead away from some of that flexibility, and put us back in the world of predefined widgets. Note that this concern does *not* depend on GWT's fundamental architecture, which is quite promising. Rather, it's a complaint about GWT's emphasis on widgets and widgety UIs. One need only look at Google Maps to see that GWT does not imply ultra-modal widget overload hell But will GWT really lead us to fine apps like that? Or will it lead us to apps that look like the config dialogs for Word (bleah)? Regardless, it's exciting to live in a world where all these great technologies are pushing and learning from one another. Compare that to the stagnant software world of ten years ago! Cheers, Paul On May 20, 2006, at 4:12 PM, Todd Orr wrote: This isn't really a Tapestry vs GWT thing. This is the latest (greatest?) push to remove the application-web disconnect. If this means that other frameworks are rendered less effective by comparison, then so be it. This is evolution at work. Some posts seem to indicate that this is just some flash in the pan technology, but there is far more at work here. The development time may be able to be accelerated to very a large degree thanks to the traditional java based GUI paradigm being exploited here. This technology also has the backing of google. At the end of the day, this is more than just an ajaxy flash in the pan. Look around you. Apps utilizing this technology are on a very sharp incline. Not because they are flashy, or at least not just for that reason. These ajaxified components allow developers to make better use of available bandwidth at the same time as building more responsive GUIs. Yes, tacos (and others) have been enabling this, but the leap here is in the learning curve, time to market, and testability. These are where GWT seems to be able to shine. Whether you like the ajax stuff or you prefer the old webapp view is immaterial. It is happening. It will likely shape the web 2.0 world. How you make use of these components is up to you, but there hasn't been anything like this available in such a clean package with such a major player backing it ever before. If you do not want to leverage these types of (maybe rehashed) technologies, that's fine. There are a lot of apps out there that do and there're not all just desktop app imitators. Check out http://techcrunch.com. There are many, many very interesting projects that are more than just desktop app wannabes. Most of these wouldn't be what they are without the aid of ajax and related technologies. GWT is compelling and doesn't sit well with devs that have finally mastered framework X. Sure, it is encouraging a change in design paradigms. That's the best part. I see the same convo popping up on many forums. Will there be competitors? Maybe, yes, who cares. IMHO, one of jee's shortcomings is the lack of focus, but that's another debate altogether. This is here. It's only in beta and it rocks already. It hits at an ideal time when development focus is on writing more efficient and more responsive, and more flashy apps. Few other frameworks are addressing this. As good as Tacos is, it's clunky by comparison. The code in java ideal is the next logical step. I remember how hard it was for my coworkers to deal with the abstractions that Tapestry offered over dealing with the servlet api directly. Eventually, these same people came to appreciate this. The technique that GWT employs is the same level of shift. We're not only going to isolate you from the servlet, we're going to isolate you from the web. This is a logical evolution.

Re: component that will get localized resources from database?
There is no obligation to use Hivemind if it is not appropriate to your problem. Hivemind is useful for decoupling parts of the system, and for making aspecty customization that cut across the framework. If you don't need decoupling, and don't need to customize across the whole framework, perhaps you don't need to bother with Hivemind. So there may be a Hivemind way to inject a different message worker into only certain classes, but I would guess overriding getMessages() is probably just fine. Did you try it? Does it work? Is it simple? If so, no worries!

In a plain Java application, you could just write your own implementation of ResourceBundle, that could take the messages from anywhere, e.g., a database, and use that instead of PropertyResourceBundle. With Tapestry, it seems to be more complicated, though. If I understand correctly, the AbstractComponent is enhanced by an InjectMessagesWorker, as defined in tapestry.enhance.xml. The InjectMessagesWorker will inject a getMessages() method that will return the result of ComponentMessagesSource.getMessages(IComponent). Now, that's not what I want... A straight-forward approach would be to override getMessages() in my own component. Would that work? To me it seems to collide with the Hivemind enhancement/injection approach. Alternatively, I could probably change the InjectMessagesWorker to something of my own liking. But that would affect *all* components (that inherit from AbstractComponent), while I would like the modified behaviour just for my own. Plus, I don't really want to mess with the tapestry.enhance.xml, since it is part of the packaged Tapestry distribution. So what would be the proper way to do it?

Just for fun (man I need a life), I tried out integrating JCaptcha (jcaptcha.sourceforge.net) into my tapernate-example application. If anyone's interested in the code, it's available via SVN at: www.carmanconsulting.com/svn/public/tapernate-example It defines a new validator type for input fields called captcha and a JCaptchaImageService engine service for rendering the CAPTCHA images. Enjoy! James p.s. I'll probably make this a component library and make it available at the tapestry-javaforge project. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] _ Piano music podcast: http://inthehands.com Other interesting stuff: http://innig.net - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [Tapestry]
Filter on the List-Id header (it should be users.tapestry.apache.org). I'd rather not have the [Tapestry] prefix, since the header is there.
