Re: Tapestry HiveDoc generation
There is a non-official maven plugin as well: http://issues.apache.org/jira/browse/HIVEMIND-164 Although I haven't tried it yet... BR: Norbi Jesse Kuhnert írta: I did sit down and figure this out finally. Hivemind has an ant task you can use to read in registry files and output them into one main registry.xml file. From there it can be transformed with xsl into whatever you want.

Re: Re: Number translator message in 4.1
I disagree with your points regarding validation errors targeting a developer audience rather than end user. First, validation errors are not likely to be the result of a programmer error, although yes, if you do supply the wrong mask, it might prove useful. More importantly, previous versions of Tapestry messages were end-user friendly enough to be used as-is AND they were already internationalized into a number of useful languages. It is pretty unlikely that there aren't large numbers of users using the default messages, precisely because they used to be more than up to the task. Again, the issue is an UNNECESSARY change in behaviour on a point release without any kind of backwards compatibility mode. And on that point, most commerical and many open source frameworks most certainly do go out of their way to provide such stability across releases. Traditionally, version numbering itself was intended to be used to indicate this. API changes generally are reserved for major version changes. The importance of adhering to this is that even the non-technical members of a development team understand this point, so it is always surprising to them that there is as much work involved in upgrading from 4.0 to 4.1 as there is. Incidentally, no one is asking open source to be free. I've been building software based on open and closed software packages for 15+ years (soft. architect or senior developer at Cisco, Akamai, Software.com/Openwave, Dreamworks, Valueclick, the UN, developer at various others), and I am well aware of what open source offers compared to commercial packages. In fact, when I was choosing Tapestry over various and sundry other frameworks, one of the things that drove me to Tapestry was the maturity and stability of the codebase. I went out of my way to look at the differences between 3 and 4 specifically so I could see what I could expect during a major version upgrade, and I liked what I saw. The API remained largely consistent, the changes in the API were well documented and, more importantly, well-justified. And perhaps most importantly, it seemed to have a supportive _community_ of developers who use it, which, as we all know, is usually the single most important factor in the usability of an open source package since the documentation is almost always greviously deficient in open source projects (although tap is better than most in that regard). As a member of that community, I think it is our responsibility to express our opinion of the direction the product is taking. HLS and other developers don't have to pay us the slightest bit of attention, of course, but if the community doesn't express a preference, what we wind up with is a framework that caters only to the unique needs of the developers which can often be fairly out of sync with what a more 'average' user requires, specifically because the developers have such deep familiarity with the API. The 'feature' in question is a nice example. It benefits a small number of users at the expense of what I imagine is the majority. So yes, I see Tap 4.1 as something of a 'Jesse special' which provides some of the changes he most wants to see, potentially at the expense of general usability of the framework for others. That's his perogative, of course, so long as the other developers agree, and I don't read the developer list often enough to be even slightly aware of what the developer process is like on Tap. Unfortunately, I don't have the cycles right now to jump in and start hacking on the tapestry source myself right now, especially 4.1, since I'm not using it. However, as a potential user, I certainly want to speak up and attempt to be heard so that 4.1 can be the best possible upgrade for Tapestry users of all stripes. Open source may not promise a no-cost platform for users, but the concept of an application development framework should promise a certain amount of stability, since its entire reason for being is to ease the development process. When was the last time the gnu C library released an API that wasn't source compatible with previous versions? What about the JDK? I actually think that a framework like Tapestry benefits by not adhering to old api in every case. The benefits of the change often outweigh the cost. But this isn't one of those cases. Not only are the benefits questionable for many users, but it shouldn't be difficult to provide support for users the old api as well. Trading application complexity for an unstable framework isn't a useful tradeoff for anyone, unless you are able to abandon development of projects built on older versions. Forking the framework source is just as inefficient as building your own framework and simply living within its limits isn't often a viable solution for long term devlopment. Listing projects that got stuck on old platforms due to platform instability doesn't support your argument. It reinforces mine. I'm sure the folks at the companies you listed would prefer
Re: Custom validator not called when value is empty?
Why not just build the set of validators for the field dynamically? Assuming you can determine whether the field should be required by the time the field rewinds (rather than being dependant on something not yet rewound), then you can include the required validator in the list only if it is actually required. However, since the 'required' validator is obviously called whether the field has a value or not, I would suggest taking a look at the source for that validator to determine where you have gone wrong with yours. It is clearly possible. Without seeing your source, that's about the best I can suggest. --sam On 12/2/06, Malin Ljungh [EMAIL PROTECTED] wrote: Good evening! I have written my own validator which works excellent - as long as a value is submitted in the field to be validated. Have I missed something here? What should I do?

Re: Re: Popup window with parameter
In general, if you want to construct a URL in Tapestry, it is best to
create an instance of ILink and then get the URL from that. Assuming
the service for which you have instantiated the iLink takes
parameters, it should be fairly self explanatory how to get the Link
to include those parameters in the URL. The classic case of creating a
redirect which will pass parameters to the external service for a page
looks like the following:
ExternalServiceParameter param =
new ExternalServiceParameter(getPageName(),
redirectExternalParams(params));
ILink link = getExternalService().getLink(false, param);
_log.debug(redirecting to: + link.getURL());
throw new RedirectException(link.getURL());
Every instance of ILink takes some parameter object which encapsulates
the entire set of parameters that can be passed. In my example,
redirectExternalParams just returns an array of Objects which will be
passed to the activateExternalPage() method when the page is loaded
via the URL created.

Re: replace @InjectPage by a page specification
I don't know for sure, but I'd try using 'IPage' as the type, which would hopefully tell hivemind to resolve the object as a page name. You might also try looking at the source for the InjectPage annotation, see how it resolves the page, presumably via a hivemind service of some kind, and then inject it via the hivemind binding, if that's possible. There is also a list of bindings at http://tapestry.apache.org/tapestry4/UsersGuide/bindings.html but I have no idea if that is the canonical list. You might try looking at the tapestry.bindings.BindingFactories configuration point. You could always contribute your own 'page' binding which would do the same thing as the InjectPage annotation does in order to load a page instance. When you figure it out, please post it back here. I don't know that I'll ever use it, but I'm sure someone will search for it at some point. --sam On 12/2/06, Cyrille37 [EMAIL PROTECTED] wrote: Hello, It's me again ...

information about trapping exception
Hello,
I'm still learning Tapestry, and generally Java Web Application ...
Now I can understand a beat about Tapestry and create little working
project.
Here is the time for me to learn how to manage errors, like trapping an
underground exception in the view layer.
The following example is from the Kent Tong 's book source code: the
shop example.
There is a page to view shop's products details:
ProductDetails(.html,.page,.java).
In ProductDetails.java there are accessors for a product details like :
public String getName() {
return lookup().getName();
}
public String getDesc() {
return lookup().getDesc();
}
public double getPrice() {
return lookup().getPrice();
}
The lookup method to get a Product is :
private Product lookup() {
return Catalog.getGlobalCatalog().lookup(getProductId());
}
In ProductDetails.page there are components like :
component id=name type=Insert
binding name=value value=name/
/component
component id=desc type=Insert
binding name=value value=desc/
/component
component id=price type=Insert
binding name=value value=price/
/component
How can I catch an exception throwed by
Catalog.getGlobalCatalog().lookup(getProductId()) when a ProductId is
not valid (does not exists) ?
I would like to display a nicer page than the default Tapestry's
Exception page.
The problem is that the exception occurs while parsing the
ProductDetails's specification page (ProductDetails.page) where
components are binded.
Have you got any idea or method on how to manage that kind of problems ?
thanks a lot for your experience share.
Cyrille.

RE: Number translator message in 4.1
Thanks for the reply, Jesse. I think my original intention was to change some of the default error messages to give more specific information about the format that we want the input to be in. Rather than just saying your input sucks, try again and having them randomly type stuff in until they get it right. I haven't looked at the messages for the other validators, but I think the old message here was pretty clear. ... must be a numeric value doesn't seem to leave much to the imagination. Perhaps ... must be a number is a little clearer. Format is #. doesn't really enhance anything, to me. If I didn't know what a numeric value was, I sure as hell am not going to know what Format is # means ;-) Perhaps the messages need to be looked at a little more closely on an individual basis, or ideally find some way to translate # type number format patterns into a more human friendly message ? Well, while I'm all for improving the user experience, I never really saw a problem with the old validator messages. Given that the new message breaks a bunch of integration tests I have, I'm even against the change ;-) Having said that, if there really was a usability issue with the old ones, I think there is merit in investigating better messages. But, keep in mind that most people will not override these strings, so I'd leave developer help messages out (or have a debug mode toggle). -- Kevin Menard Servprise International WebReboot -- Remote Reboot Without Pulling the Plug 800.832.3823 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Number translator message in 4.1
Sure, I can see the validity in the particular case of a simple number format for numeric values. (except of course what will happen when they input 3.14 ?) As I've run out of time to really properly play with these for 4.1.1 I may have to just revert to the old messages for now, but this is definitely not the last you've heard of these kinds of changes. ;) We have a sort of skunkworks project taking hold in the confines of the dojo foundation to help attack usability (for end users of applications) in general, so it's something I'll be attempting to incorporate into Tapestry when possible. I know very little about the area comparatively, but the others involved in the project are really the best the industry has to offer - so it'll be an exciting time in the next few releases.

The discussion isn't really about the message changes. It was just sparked by them.

Re: information about trapping exception
In hivmind.xml:
contribution configuration-id=tapestry.InfrastructureOverrides
property name=exceptionPageName value=CustomExceptionPage/
/contribution
In your template for the custom exception:
span jwcid=exception/
will render the exception if you have the following in your .page file:
component id=exception type=ExceptionDisplay
binding name=exceptions value=ognl:exceptions/
/component
You can also use the following to render the request
component id=request type=RequestDisplay /
My class looks like this:
public abstract class CustomExceptionPage extends StaticBasePage
implements PageDetachListener {
public abstract void setExceptions(ExceptionDescription[] exceptions);
private static Logger log = Logger.getLogger(CustomExceptionPage.class);
public void setException(Throwable value)
{
log.error(value, value);
ExceptionAnalyzer analyzer = new ExceptionAnalyzer();
ExceptionDescription[] exceptions = analyzer.analyze(value);
setExceptions(exceptions);
}
}
I don't remember where I got all that from, but it was either Kent
Tong's book or the user guide on the Tapestry website. There is a
small chance I found it in Tapestry in Action which is the Tap 3
book.

binding name=value value=name/
/component
component id=desc type=Insert
binding name=value value=desc/
/component
component id=price type=Insert
binding name=value value=price/
/component
How can I catch an exception throwed by
Catalog.getGlobalCatalog().lookup(getProductId()) when a ProductId is
not valid (does not exists) ?
I would like to display a nicer page than the default Tapestry's
Exception page.
The problem is that the exception occurs while parsing the
ProductDetails's specification page (ProductDetails.page) where
components are binded.
Have you got any idea or method on how to manage that kind of problems ?
thanks a lot for your experience share.
Cyrille.

Re: information about trapping exception
I believe that also gets covered on the website:
http://tapestry.apache.org/tapestry4.1/developmentguide/exceptionpages.html

In hivmind.xml:

property name=exceptionPageName value=CustomExceptionPage/
/contribution
In your template for the custom exception:
span jwcid=exception/
will render the exception if you have the following in your .page file:
component id=exception type=ExceptionDisplay
binding name=exceptions value=ognl:exceptions/
/component
You can also use the following to render the request
component id=request type=RequestDisplay /
My class looks like this:
public abstract class CustomExceptionPage extends StaticBasePage
implements PageDetachListener {
public abstract void setExceptions(ExceptionDescription[] exceptions);
private static Logger log = Logger.getLogger(CustomExceptionPage.class);
public void setException(Throwable value)
{
log.error(value, value);
ExceptionAnalyzer analyzer = new ExceptionAnalyzer();
ExceptionDescription[] exceptions = analyzer.analyze(value);
setExceptions(exceptions);
}
}
I don't remember where I got all that from, but it was either Kent
Tong's book or the user guide on the Tapestry website. There is a
small chance I found it in Tapestry in Action which is the Tap 3
book.

Hello,
I'm still learning Tapestry, and generally Java Web Application ...
Now I can understand a beat about Tapestry and create little working
project.
Here is the time for me to learn how to manage errors, like trapping an
underground exception in the view layer.
The following example is from the Kent Tong 's book source code: the
shop example.
There is a page to view shop's products details:
ProductDetails(.html,.page,.java).
In ProductDetails.java there are accessors for a product details like :
public String getName() {
return lookup().getName();
}
public String getDesc() {
return lookup().getDesc();
}
public double getPrice() {
return lookup().getPrice();
}
The lookup method to get a Product is :
private Product lookup() {
return Catalog.getGlobalCatalog().lookup(getProductId());
}
In ProductDetails.page there are components like :
component id=name type=Insert
binding name=value value=name/
/component
component id=desc type=Insert
binding name=value value=desc/
/component
component id=price type=Insert
binding name=value value=price/
/component

Catalog.getGlobalCatalog().lookup(getProductId()) when a ProductId is
not valid (does not exists) ?
