T5 br troubles
I might be wrong, and for sure it's not critical but I found out the following behavihour when including br tags in my component: component output result br/ br parsers warn that br is not properly closed br none Tapestry wisdomely throws an exception Tag neds end tag /br none Tapestry misses de point and complains on certain div Just in case someone else has found the same behavihour...Tapestry 5.0.11 Thanks -- View this message in context: http://www.nabble.com/T5-%3Cbr%3E-troubles-tp17289805p17289805.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: EventLink and context from page
You understood me very correcltly :) But I have loop with products and each product has 'add to cart' link. AFAIK it's not possible to use ActionLink in loop, cause every ActionLink must have unique id and when I don't know how many items will be in the loop it's hard do write methods connected to each AcionLink. PageLink, which you mentioned. seems to be created to different purposes... so problem is still unresolved :) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: EventLink and context from page
Stick in a single action link. It will take care of uniquifying its id. Then write a single handler. Put the instance-specific information in the context for the action link, and then your handler can accept that info as method parameters.

Re: Question about select component
Hey,
Assuming you are using version 5.0.11, you can add: blankoption=never to
the component definition.
See details here:

how can I call a web url from actionlink
Hi,
I would like to have a link, where on click first some cleanup action will be
done,
like for example closing a database connection etc, and then finally redirekt
the
user to some absolute URL in the web.
How can I accomplish this?
I have something like this:
a href=# t:type=actionlink t:id=quitGameQuit/a
@OnEvent (component=quitGame)
Object onQuit(){
memory.quit();
// more things to do before quitting
return ?? // go to http://www.someOtherWebspace.com;;
}
thank you!

Little confused
Hi, here is my problem. I have a bean on my java page, but i am not using the beaneditorform component to create a new one. Acording to Alexander book, the beaneditorform component can handle the initialization of the bean, so you dont have to create one. As i am not using this component, should i define the bean with a sentence like this: private Matafuego matafuego = new Matafuego(); or should i create the new instance on the onActivate method? I tryied the first approach, but the bean is always the same (i guess because of the page pooling mechanism). What is the right approach to this? Thanks very much.
Re: Little confused
I would probably use a lazy getter with a @Persist attached to the field.
Something like:
@Persist
private Matafuego matafuego;
public Metafuego getMetafuego()
{
if (null == metafuego)
{
metafuego = new Metafuego();
}
return metafuego;
}
The page instance is guaranteed to be accessed by only a single thread at a
time, so that should be safe for you.

Re: Little confused
Thanks for your answer, but i still have the same issue. Maybe i am not
explaining the problem ok. I have a page with a link, when i press the link
the application goes to the new Matafuego page, where i am using a hand
made form (i mean not using beaneditorform tag). The first time i do this,
everything works fine, i complete the date press Save and the application
redirects to the main page again. But the second time i press the link to
add a new Matafuego, the form has the data i complete on the first one. The
behavior i am looking here, is that each time i access the form, i create a
new Matafuego, i mean a clean form and a new Matafuego instance.
Thanks in advance.

Set your private variable to null in your onSuccess function.

Re: Little confused
Hi Ned, the onSuccess methos is executed before the onSubmit, so that would
not work for me because i am doing the model logic on the onSubmit. I tryed
setting my variable in null after executing my businnes logic, but i still
have the same issue. My private variable should not be cleaned by Tapestry
pooling mechanism?
The only thing i can think to fix this, is to set my variable to null after
the bussines logic, and then on the onACtivate method check if its null, the
i create a new one, if its not null then i do nothing.
Thanks, and still waiting for an elegant solution to this ;)

Re: Little confused
It doesn't really matter where you clear it. Just clear it when you're done with it. As for the lifecycle question, you have to clear it because you @Persisted it. If you didn't @Persist it, you wouldn't have to clear it, but you'd likely lose your data when working with the form, depending on your workflow. This should work fine. I do it all the time. -- Kevin On 5/17/08 12:34 PM, Manuel Corrales [EMAIL PROTECTED] wrote: Hi Ned, the onSuccess methos is executed before the onSubmit, so that would not work for me because i am doing the model logic on the onSubmit.

Re: Using t5-components
looks like the jars not copied in your WEB-INF/lib directory
2008/5/17 Toby Hobson [EMAIL PROTECTED]:
Hi
I'm looking at the t5-components project and I am trying to use the
PagedLoop component. I've added the commons and contrib dependencies and the
repo to my pom.xml and they are now on my classpath. But when I try to use
li t:type=t5components/PagedLoop source=images value=photo
${photo.name}
/li
Tapestry complains that it can't find a component called
t5components/PagedLoop. Do I have to somehow tell T5 where to find the new
components?
Thanks
Toby

Re: Little confused
Ok, thanks. Probably this is some stupid begginer mistake, but i cant make
this work. My class is this:

@Component
private Form nuevoMatafuegoForm;
@Component(id = nroAparato)
private TextField nroAparato;
public SelectModel getTiposDeMatafuego() {

}
public Matafuego getMatafuego() {
return matafuego;
}
public void setMatafuego(Matafuego matafuego) {
this.matafuego = matafuego;
}
void onActivate() {

return this;

}
}
As you can see, the matafuego instance is not @Persist, so i really do not
undestand why is not being cleared. Also if instead of doing Matafuego
matafuego = new Matafuego(); on the declaration, i dont initialize it, then
when i try to save it, it is null in the onSubmit method.
Any suggestion?

}
@OnEvent(value = submit, component = nuevoMatafuegoForm)
Object onSubmitNuevoMatafuegoForm() {
MatafuegoFacade facade = new MatafuegoFacade();
try {
facade.guardarMatafuego(matafuego);
matafuego = null;
return MainMatafuegos.class;
} catch ( ConstraintViolationException e) {
nuevoMatafuegoForm.recordError(nroAparato,
messages.get(matafuegoDuplicado));
return this;
}
}
}
As you can see, the matafuego instance is not @Persist, so i really do
not undestand why is not being cleared. Also if instead of doing Matafuego
matafuego = new Matafuego(); on the declaration, i dont initialize it, then
when i try to save it, it is null in the onSubmit method.
Any suggestion?

It doesn't really matter where you clear it. Just clear it when you're
done
with it. As for the lifecycle question, you have to clear it because
you
@Persisted it. If you didn't @Persist it, you wouldn't have to clear
it,
but you'd likely lose your data when working with the form, depending on
your workflow.
This should work fine. I do it all the time.

Re: T5: Exception Handling
Hi Leon,
How to override server error pages depends on what server you're using.
As far as I'm aware it's unfortunately not possible to use Tapestry
pages as server error pages - if I'm wrong here, I'd really like to know
how to do it. :)
What I mean by turning the RequestExceptionHandler into a pipeline is
that I've overridden the original service with my own that uses a pipeline.
http://tapestry.apache.org/tapestry5/tapestry-ioc/pipeline.html
So I define my filter:
public interface RequestExceptionFilter {
void handleRequestException(Throwable exception,
RequestExceptionHandler handler)
throws IOException;
}
Then I create a new RequestExceptionHandler as a pipeline:
public static RequestExceptionHandler
buildImprovedRequestExceptionHandler(
ListRequestExceptionFilter configuration,
@InjectService(RequestExceptionHandler) RequestExceptionHandler
requestExceptionHandler,
PipelineBuilder builder,
Logger logger
) {
return builder.build(
logger,
RequestExceptionHandler.class,
RequestExceptionFilter.class,
configuration,
requestExceptionHandler
);
}
I then contribute this to AliasOverrides to replace the default
RequestExceptionHandler:
public static void contributeAliasOverrides(
ConfigurationAliasContribution configuration,
@InjectService(ImprovedRequestExceptionHandler)
RequestExceptionHandler requestExceptionHandler
) {
configuration.add(AliasContribution.create(RequestExceptionHandler.class,
requestExceptionHandler));
}
I can then contribute filters to the pipeline like this:
public static void contributeImprovedRequestExceptionHandler(
OrderedConfigurationRequestExceptionFilter configuration,
RequestExceptionErrorFilter requestExceptionErrorFilter
) {
configuration.add(Error, requestExceptionErrorFilter);
}
Where RequestExceptionErrorFilter looks like this:
public class RequestExceptionErrorFilter
implements RequestExceptionFilter {
private final RedirectService redirectService;
private final SecurityService securityService;
private final Logger logger;
public RequestExceptionErrorFilter(RedirectService redirectService,
SecurityService securityService, Logger logger) {
this.redirectService = redirectService;
this.securityService = securityService;
this.logger = logger;
}
public void handleRequestException(Throwable exception,
RequestExceptionHandler handler)
throws IOException {
if (securityService.isProductionModeEnabled()) {
logger.error(Exception during request, exception);
redirectService.sendRedirect(ErrorIndex.class, false);
}
else {
handler.handleRequestException(exception);
}
}
}
RedirectService and SecurityService are my own classes. They just make
some things easier for me. As you can see I show an error page when I'm
in production but invoke the next filter in the pipeline if I'm not. You
could contribute more filters if needed.
I've been wanting to contribute a strategy filter before this one
allowing to do different things depending on the type of exception
thrown, but haven't had the time nor need to do so yet.
http://tapestry.apache.org/tapestry5/tapestry-ioc/strategy.html
Anyhow, hope this helps - if not, you know where to ask. :)

Thanks Peter,
Your original question in the post is also what I would like to know.
Do you now know how to override server error pages(404, 505 etc)?
And I don't understand what Flip means with :I've turned the
RequestExceptionHandler service into a pipeline.
Can you show me some code of how to do this?

Hi Leon
I posted a number of questions to the list about this topic, but got
only a few perls. One of them was this post, particularly Filip's answer:
http://www.mail-archive.com/users@tapestry.apache.org/msg21914.html
Also see this page, for how to override Tapestry's error page with
your own friendly error page:
http://wiki.apache.org/tapestry/Tapestry5ExceptionPage
I am not sure what you are trying to do, but would suggest you
familiarize yourself a bit more with Tapestry's error reporting
mechanisms, which imho are incredibly powerful and easy to use.
Hope this helps,
Peter

Subject: T5: Exception Handling
Hello
What is the best way to handle exceptions in Tapestry 5?
I want to show some kind of general error page, when an exception occurs.
At the moment I have a onException method in my BasePage class. But
for some reason the Error page is not returned.
What is the way in T5 to handle exceptions?
Object onException(Throwable cause) {
return new Error();
}
Re: EventLink and context from page
What he said. So you do this:
Page class:
@Property
private Product product;
public ListProduct getProducts() {
// return the products you want to show
...
}
// or onAddToCart(Long productId) if you feel like using EventLink
Object onActionFromAddToCart(Long productId) {
// load the product and do whatever you need to do with it
...
// redirect to shopping cart or wherever
}
Page template:
t:loop t:source=products t:value=product
!-- display the product --
t:actionlink t:id=addtocart t:context=product.idAdd to
cart/t:actionlink
...
/t:loop
Hope that helps.

Stick in a single action link.
It will take care of uniquifying its id.
Then write a single handler.
Put the instance-specific information in the context for the action
link, and then your handler can accept that info as method parameters.

You understood me very correcltly :)
But I have loop with products and each product has 'add to cart' link.
AFAIK it's not possible to use ActionLink in loop, cause every
ActionLink must have unique id and when I don't know how many items
will be in the loop it's hard do write methods connected to each
AcionLink.
PageLink, which you mentioned. seems to be created to different
purposes... so problem is still unresolved :)

Re: Little confused
Hi,
I've found the following pattern to work very well - at least I use it
everywhere on several sites in production with no problems. :)
@Property
private Item item;
// I have a form in my template with t:id=add
void onPrepareFromAdd() {
if (null == item) item = new Item();
}
void onSuccessFromAdd() {
// go about my business with the item
...
// I'd normally return here, but since you need
// something done in onSubmit...
}
Object onSubmitFromAdd() {
// do what you need to do
return ...;
}
I sometimes persist the item if needed.
Hope this helps.

Hi, here is my problem. I have a bean on my java page, but i am not using
the beaneditorform component to create a new one. Acording to Alexander
book, the beaneditorform component can handle the initialization of the
bean, so you dont have to create one. As i am not using this component,
should i define the bean with a sentence like this:
private Matafuego matafuego = new Matafuego();
or should i create the new instance on the onActivate method?
I tryied the first approach, but the bean is always the same (i guess
because of the page pooling mechanism). What is the right approach to this?
Thanks very much.

Re: Javascript error in datefield component
I upgraded my project to 5.0.11 and I still have this problem. On Firefox 2, the datepicker is visible, but is not aligned closely to the datefield - it appears on the far left corner of the browser. On IE 7 it errors out, and does not show. For my project, all I did was download the t5demo war file from http://code.google.com/p/tapestry4nonbelievers/downloads/list, and then removed the 5.0.10 files from the lib folder and added the 5.0.11 files.
