Re: java.util.ConcurrentModificationException in portlet when trying to show ArrayList
No idea of the exact cause in your case, but in general, this exception means that you modified a collection while iterating over it. In your case, it looks like collection returned by getNewslist() is somehow getting modified. Try returning this instead: return Collections.unmodifiableList(newslist); ...and then you'll get an exception at the point when the collection is modified, which will help you find the source of the problem.

Re: JSF-style bean access (JBoss) via HiveMind ?
I don't know whether it works, but I presume you tried this:

This works, but is a bit cumbersome:

And this fails:

While I'm not surprised by the failing example, I do wonder: what
are the rules for the @InjectObject annotation? Can we use OGNL
(or ognl-like) expressions within its parameter? The docs state
that the value is a "HiveMind object reference". So, rephrasing
the question:
How do I bind the results of something like the ognl expression:
"infrastructure:context.getAttribute('RoleModule')" to an HiveMind
object? What's the hivemodule.xml incantation?

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;
}
Cheers, P

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?

I expected that adding this annotation would allow me to name the
template "Foo.xml" instead of "Foo.html":
@Meta("org.apache.tapestry.template-extension=xml")

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

Tomcat's deploy / undeploy tasks are quite speedy, but I've found that Tomcat starts going haywire after a few dozen hot deploys like that -- usually it runs out of memory; sometimes the old instance doesn't undeploy cleanly, and holds on to DB connections ... sometimes, it gets into a confused internal state where new deploys fail with mysterious errors, and I have to delete its temp directories. For some reason, the hot deploy seems to work flawlessly for some and fail for others. I'm in the latter group -- I find that I have to restart Tomcat every hour or so.

Re: best development server for Tapestry
I've had good luck developing with Jetty 6. Unlike Tomcat, it's quite easy to set up an "ant jetty" target which launches a server, then just kill the process and run ant again for the next dev cycle. Tomcat's hot deploy ought to make this easy, but I've had too many resource leak, out of memory, and general "Tomcat goes haywire" issues with the hot deploy to make it good for development. I'm much happier with Jetty's clean restart approach. That's not necessarily an endorsement / criticism of either in production, of course.

Adding form elements with Javascript
Sorry to interject an actual Tapestry question into all the exciting talk about logos and GWT! I have a form with a bunch of text fields inside a @For. I want my page to have a "new item" link that uses Javascript to add a new element to the form. My Javascript works great on the client -- new TextFields appear just fine. But this adds unexpected components to my form, and of couse I get a stale link error. How do I prevent the stale link? Do I use Javascript to manually modify the hidden field that lists the components in the form? i.e. use Javascript to turn this: ...into this: value="items,Hidden,TextField,Hidden,TextField,Hidden,TextField,Submit"/ > ...? Yuck! Is there a better way? I'm sure this must have been covered on the list or in the docs, but I searched and couldn't find it. Any pointers in the right direct would be welcome.

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!

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. The Web is just another view technology. I should be able to work wi
Re: Google Web Toolkit
For people writing single-page Ajaxy apps that look like Swing, GWT may well be the death knell for other frameworks. For other types of apps, I'm not so sure. And I'm not so sure that the former type of app is something I want to see more of. I don't necessarily like the trend toward the single-page Ajax app that resembles a desktop app. Why? Desktop apps generally suck. They attempt to stuff any sort of data structure, any sort of interface semantics, into the same set of widgets provided by the platform. The result is a sort of widget soup, lots of dialogs with subdialogs, all highly modal (excessive modality being a bad thing.) See the Windows network config dialog for an extreme example. Something I love about webapps is that they've broken the shackles of the widget set: people use creative markup to represent their data structures in all sort of inventive ways. Granted, many web UIs suck, but on the whole, I prefer the average webapp's UI to the average desktop (well, Windows) or Swing UI. So don't get me wrong; it's still very, very cool -- but I have mixed feelings about GWT. Will it encourage a step backwards in UI design, back to the dark days of modal widget soup? Perhaps not, but such is my misgiving. Cheers, Paul On May 20, 2006, at 11:35 AM, Todd Orr wrote: The more I use the GWT, the more impressed I am. This could be the killer framework java has needed.

This may be heresy, but as much as Tapestry was an improvement over Struts (and many other MVCs), it seems that GWT (IMO) is that much further towards the ideal solution over Tap. Don't get me wrong, I love Tapestry for what it has done and the impression it has made in the community. I fondly remember the feeling of freedom from moving away from Struts.

Voting on the logos
At the risk of opening yet *another* can of worms -- yes, I apologize in advance -- can we please use a Condorcet method for tallying the votes if we do have a logo contest? Here are lots of technical details for those who don't know the term... http://en.wikipedia.org/wiki/Condorcet_method http://condorcet.org/rp/index.shtml ...but the bottom line is that Condorcet voting methods work *much* better than a normal plurality (vote for one) or instant runoff vote -- especially when there are many choices, as there clearly will be in this contest. Debian and Gentoo have both been using Schultze's method, which is a type of Condorcet method, quite successfully for some time now. Free software is available for tallying the votes.

Re: new logo for Tapestry
Hate to break it to you, but management has *no* idea what the Apache feather looks like or means. Sorry! I do think the "tryout factor" for developers is a good point. However, I think the more common approach of placing the Apache logo alongside ours serves all the purposes you mention, without burdening the logo. And it *does* burden the logo. The Apache project logos attempting to integrate a feather generally don't look as good, IMO. Geronimo? Eh. Boring. Didn't even see the feathers until I was looking for them. Spamassasin? Tomcat? Ant? Slick! Looking sharp!

I'd wager that we would have easily twice the try-out factor if the Apache refernce was clear rather than not, which would benefit Tapestry (and us) in the end. Then again, it doesn't have to be the feather, it might be tricky to integrate in the "T" design tat forms the base of most proposals.

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? Can I override the "inject-messages" command from "tapestry.enhance.xml" for my own components? How?

Re: I do not like the new tapestry logo
Actually, Medieval tapestry was the first thing that came to mind when I saw the new logo. I do agree, however, that it's a little odd -- something about the proportioning, the position of the horn, or the pose of the unicorn...? It almost seems to be tipping backwards, out of balance or bent awkwardly. I do, however, prefer something evoking the "heraldic imagery" to the bland old T, which was fine but boring. The concept seems good to me. Then again, is that why Tapestry is named Tapestry? I think the idea is that it weaves together all these components to make a page.

Re: Page files or annotations? [was: Validation]
I think Sam has it right: it depends. In my development, I never write page files -- but we don't have any separate person devoted to the page design. That seems like the only compelling case left for the page files, but it is somewhat compelling: it keeps as much as possible out of the page file, so the designed can focus on the HTML and not have to tiptoe over so much extra baggage. (One can of course use annotations to achieve that, too, but it requires declaring tons of getXyzComponent() methods that clutter up classes.) However, without the separate designed role, I find the annotations approach keeps things much cleaner. Unless you're keen on keeping the templates as pared-down as possible, then, I'd recommend that. In Tap 5, it sounds like things are moving towards annotations only. Hopefully 5 will reduce the verbosity of some of the common cases.

I think it depends on the size of your team and complexity of your app. With a fairly large team, including one person devoted to layout, I prefer to keep all component declarations in .page files, so that the layout templates are as clean as possible and least likely to get screwed up by someone making edits without a clue about how tapestry works. I've generally got nothing but jwcid attributes in my templates. A simple macro in just about any editor will make it easy to switch between .page and .html files in a single keystroke or mouse click, so the complaint about having to switch files really isn't valid, to my mind. We also attempt to keep components in the same order in the .page file as they are used in the .html template. It is a couple of minutes of developer time per page at the end of any release cycle on any pages that have gotten out of whack and it keeps things easy to find. In fact, I have a macro in vim which will switch to a .page file and go to the same location as I am currently at, as a percentage of the file length, with two keystrokes. Odds are usually good that I can see the component that I am looking for as soon as the other file is visible, and both files are so much more readable as a result. The only thing I hate is when informal parameters are important to the function of the component, since, as far as I know, they must appear in the html file. I really wish there were a way to bind informal parameters to a component from within a .page file, overriding any informal parameters of the same name that are in the .html template which may be necessary for layout in the unrendered page. That way, I could put ALL of my parameter bindings in the .page file. --sam - 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 to generate mails ?
I am interested in your EmailService, and I'm sure others would be, too. Your point about dynamic content is a good one: it's quite likely that an email would contain ExternalLinks, PageLinks, and perhaps even stateless DirectLinks -- and it would be nice to generate those in the email exactly as we generate them in a page. Cheers, Paul On May 8, 2006, at 4:36 PM, Henri Dupre wrote: I don't agree on this... Also I don't see really differences between "static" email and interactive HTML. In the emails we generate, there is lots of dynamic content although there is no form handling, we use the same components plus many other tapestry features. Velocity is fine, but not when you start to have complex emails. What makes tapestry great for this task are the templates. In addition, I rather not add another technology to our project, Velocity is simple, but just *more* to learn and manage for our other developers. And I'll give you a very usefull usage of sending html pages: for exceptions, we send the tapestry error page by email (in tapestry 3) while we give to the client a friendly error page. Logging is fine but it doesn't give you all the detailed info of an error. I've been working on an EmailService for T4, you can inject it in any page and the interface is quite simple. It takes a list of properties (for email headers, from/to/subject), a page (String or object) and eventually an object map if you want to call the external interface of your page. It is working 90% now and it is relying on a fresh request cycle, so it will be possible to thread the whole thing. Getting a fresh request cycle requires quite a bit of hacking, I may need to write a specific engine object. I can post the code on the wiki once I'm done if anyone is interested.

A probably controversial attempt at improving template readability
I decided that I've had it up the wazoo with typing (and looking at)
"ognl:" all the time. Probably my least favorite things about
Tapestry is the eye-bending verbosity of its template files -- the
previewability is fantastic, but it comes at a *high* price in
keystrokes and readability, IMO.
I have a new approach I'm somewhat happier with, and thought I'd
share it so that everyone else can either try it out or decry my
foolishness, as they see fit.
I added this to my hivemodule.xml:
id="tapestry.bindings.OGNLBindingFactory"/>
id="tapestry.bindings.MessageBindingFactory"/>
id="tapestry.bindings.LiteralBindingFactory"/>
id="tapestry.bindings.AssetBindingFactory"/>
id="tapestry.bindings.BeanBindingFactory"/>
id="tapestry.bindings.ListenerBindingFactory"/>
id="tapestry.bindings.ComponentBindingFactory"/>
id="tapestry.bindings.StateBindingFactory"/>
id="tapestry.bindings.HiveMindBindingFactory"/>
This makes allows me to write ":value" instead of "ognl:value" ...
which seems like a very small thing until you see how it cleans up
template files! It also creates one-letter prefixes for all the other
bindings. (Specific choices here are a matter of taste -- I like the
caps so that I don't have to twiddle the shift key back and forth to
type quote - prefix - colon, but one could easily change this.)
Unfortunately, Tapestry is one step ahead of me, and actually seems
to intentionally to prevent what I'm doing. (Sorry, HLS, if you are
gritting your teeth as you read this!) In BindingSourceImpl:
public IBinding createBinding(IComponent component, String
bindingDescription,
String reference, String defaultPrefix, Location location)
{
...
int colonx = reference.indexOf(':');
if (colonx > 1)
{
String pathPrefix = reference.substring(0, colonx);
...
In other words binding prefixes are customizable, but they must be at
least two characters.
Soo, I just overrode the default binding factory:
id="tapestry.bindings.BindingFactories"/>
public class InnigBindingSourceImpl
implements BindingSource
{
private List contributions;
private Map factoriesByPrefix = new
HashMap();
public void initializeService()
{
for(BindingPrefixContribution c : contributions)
factoriesByPrefix.put(c.getPrefix(), c.getFactory());
}
public IBinding createBinding(IComponent component, String
bindingDescription, String reference,
String defaultPrefix, Location
location)
{
String prefix = defaultPrefix;
String path = reference;
int colonx = reference.indexOf(':');
if(colonx != -1)
{
String pathPrefix = reference.substring(0, colonx);
if(factoriesByPrefix.containsKey(pathPrefix))
{
prefix = pathPrefix;
path = reference.substring(colonx + 1);
}
else
throw new ApplicationRuntimeException(
"Unknown binding prefix \"" + pathPrefix + "\"
in expression \"" + reference + '"');
}
return factoriesByPrefix.get(prefix).createBinding
(component, bindingDescription, path, location);
}
public void setContributions(List
contributions)
{ this.contributions = contributions; }
}
(Note that this code explicitly requires the use of "literal:" or
"-:" if a binding contains a colon. This prevents me from having a
literal accidentally turn into some other kind of binding in a future
upgrade.)
Combined with this, I've abandoned the use of as a generic
"Tapestry-only" tag, and am now using for @If, for @For,
and for @Insert.
Before:
parameters="ognl:article">
value="ognl:article.title">Article Title
After:
parameters=":article">
Article
Title
It's still not as concise as Velocity or Rails's ERB, but it *is*
still code-free (unlike ERB) and browser-previewable (unlike both).
I'm definitely happier with it. I still don't like the redundancy of
, and don't like the verbosity of the @Insert
Cheers,
Paul
