Hello Thank you all for your great support! I am using Tapestry 5.2.6. I just found out something what causes this issue. I use a breadcrumb component with a BreadCrumbDispatcher see https://github.com/argoyle/tapestry-breadcrumbs When I don't use this breadcrumb mechanism, everything works fine. When I use this component, I get the error only after I have cleared my web history (cache, cookie etc) and I guess also when my session has expired.

This also works... and now we don't have to set the previousPage to null.
public static ReferrerRequest fromUri(final String uri, final Request request)
{
if (uri == null) {
return null;
}
final String serverRegexp = ^.*:// + request.getServerName() + (: +
request.getServerPort()
+ )? + request.getContextPath();
if (!uri.matches(serverRegexp + .*$)) {
return null;
}
final String path = uri.replaceFirst(serverRegexp, );
int index = path.contains(;jsessionid) ? path.indexOf(;jsessionid)
: path.length() - 1;
return new ReferrerRequest(path.substring(0, index), request);
}

Hi,
I have had the same issue with the Breadcrumb component.
The problem is that the referrer contains a ;, which comes from

decodePageRenderRequest doesn't like the ;

I just check the string for ; and set previousPage to null if is true. I've

Hello Thanks for your answer. At the moment I am working with Blocks and a t:delegate to=activeBlock/ I think it is almost working, but I want to handle the change event and update the activeBlock when changing the value in the select box. How can I do that? Why do I need a Zone to handle the change event? Because I want to be free in using zones or not. In my case the zone div breaks my page layout... On entering the page, the activeBlock is working fine. Now I only need to handle the change event from the select.

For input fields (such as TextField) you can add a parameter translate
of
type FieldTranslator which translates between the object (e.g.
BigDecimal)
and the String representation in the input.
See:
http://tapestry.apache.org/current/tapestry-core/ref/org/apache/tapestry5/corelib/components/TextField.html
You can also define your translator globally by contributing to
TranslatorSource.

I tried to use a zone, but the zone div is automatically moved to the top of the page and I don't want that. How can I show/hide tr elements based on the value I have selected? regards, Leon tr class=even thType/th td select t:type=select t:id=typeSelect value=type/ /td /tr t:block id=blockHighLow tr class=odd thHigh/th td input type=text size=50 / /td /tr tr class=even thLow/th td input type=text size=50 / /td /tr /t:block t:block id=normalBlock tr class=odd thNormal/th td input type=text size=50 t:type=textfield t:id=usageInput value=energyBill.consumption.value / /td /tr /t:block
Re: How to implement nested components?
Thanks for your reply!
Actually, I want to know how to implement nested components. I will show you
my scenario:
1. Requirment: A wizard that include some step to guide users complete a
task, e.g. a sale order
2. Current Implementation: I implemented two components Wizard and
WizardStep, and use them like this:
t:wizard steps=[step1,step2,step3]
t:wizardStep name=step1
step1 content
/t:wizardStep
t:wizardStep name=step2
step2 content
/t:wizardStep
t:wizardStep name=step3
step3 content
/t:wizardStep
/t:wizard
// wizard class
@Property
private WizardStep[] steps;
in this way, I need to pass WizardSteps as Property. But I want to use them
as follows:
t:wizard
t:wizardStep name=step1
step1 content
/t:wizardStep
t:wizardStep name=step2
step2 content
/t:wizardStep
t:wizardStep name=step3
step3 content
/t:wizardStep
/t:wizard
//wizard class
@Inject
private ComponentResources resources;
private WizardStep[] steps;
@SetupRender
private viod setupRender(){
//initialize steps by iterate child components
steps = initSteps();
}
//I want to use ComponentResources to get WizardSteps ids then use
getEmbeddedComponent() to get WizardStep instance.
private void initSteps() {
ListString stepIds =
resources.getComponentModel().getEmbeddedComponentIds();
//Why stepIds is empy! so the follows codes will never execute!
steps = new WizardStep[stepIds.size())];
int i = 0;
for (String stepId: stepIds){
steps[i++] = resources.getEmbeddedComponent(stepId);
}
}
I am really confused, what's wrong with my second implementing?
Any suggestion? Thanks!

All components are nested, so I don't know what you're asking. A non-page
component instance doesn't exist outside a page, which is almost the same as
a component, so all components are nested.
I tried to inspect the component in debug model, but they're all null
objects, I'm using IDEA 10, I don't know if is caused by IDE or Tapestry
IoC.
This is not caused by the IDE or Tapestry-IoC, but by Tapestry(-core)
itself. It was already solved for 5.3-SNAPSHOT.
So how could i trace a component's lifecycle?

How to implement nested components?
Hi all,
I have a requirement to implement nested components, it like this:
t:comA
t:comB/
t:comB/
t:comB/
/t:comA
I have created components, but I can't access embedded components in comA:
public class comA {
@Inject
private ComponentResources resources;
void setupRender() {
ComponentModel model = resources.getComponentModel();
ListString embeddedIds = model.getEmbeddedIds();
// The problem is that embeddedIds.size() is 0!
}
}
So, Is this a wrong way? I'm so confused.
Any idea? thanks!

Re: [T5] 5.0.17 URLEncoderImpl.decode error
He Martijn,
The URL is not really generated. I was playing with Freemarker (Java
template engine).
I tried it to send a mail...
The URL is in the mail template and the email param is replaced by
freemarker:
a href=http://localhost:8090/tapestry/test/user/${user.userEmail}/
My test was to send an email with freemarker with a link in it. I want
to be able to click that link and show the email on the screen.
So for me it is not handy that the URL encoding has changed, because I
can not use the org.apache.tapestry5.internal.services.URLEncoderImpl
inside my template.
Any ideas how I can solve this?
greetz,
Leon
Martijn Brinkers wrote:
I guess the URL is generated outside of Tapestry? because if you

You can probably use the default encoder implementation if you want to

Re: What's the easiest way to implement two dependent select lists ?
Indeed I agree with Hugo.
I had this use case a couple of times and solved it in the same way as
Hugo did.
I also hoped there is an easier way to implement dependable selects,
using zones...
Also filling selects with objects is not really easy. I need to
implement a selection model and a value encoder.
I have the feeling that things are more complicated than they should be.
For example, it would be easier to add a select into my page and bind a
list with objects to it with setting the labelField and idField to
object properties.
So like this;
select t:type=select t:id=productSelect model=productList
labelField=name, idField=id value=selectedProduct /
I get the feeling that sometimes tapestry 5 is doing things to complicated.

Here's how i'm doing this now:
On the source select i'm using the OnEvent mixin to fire the change
event:
select t:id=operator t:type=select t:mixins=commons/onEvent
t:event=change t:onCompleteCallback=onCompleteOperatorChange .../
The event listener method is then responsible for querying the
database for
the value to be set in the destination select:
@OnEvent(component = operator, value = change)
public JSONArray onChangeOperatorEvent(String value) {
JSONArray jsonArray = new JSONArray();
for (Plaza plaza : getDestinationSelectValues(value)) {
JSONObject jsonObject = new JSONObject();
jsonObject.put(value, plaza.getId());
jsonObject.put(label, plaza.getDescription());
jsonArray.put(jsonObject);
}
return jsonArray;
}
Finally, the onCompleteOperatorChange javascript function has to
parse the
return JSON and update the select input options:
function onCompleteOperatorChange(response) {
selectElement = $(entryPlaza);
responseJSON = response.evalJSON();
while (selectElement .options.length 0) {
selectElement .options[0] = null;
}
for (index = 0; index responseJSON .length; index++) {
selectElement.options[index] = new Option(responseJSON
[index].label, responseJSON [index].value);
}
Tapestry.ElementEffect.highlight($(entryPlaza));
}
It would make things a little easier if the selects weren't inside a
form
because then my event listener method could return the component
instance
itself and then on the client i would just have to replace the current
element with the new rendered one.

I'm curious how a Tapestry expert would handle it.

Maybe i'm missing something.

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. :)

) {
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.

Hello
I found this example:
new JSONArray([['a', 'value a'], ['b', 'value b'], ['c', 'value c'],
['d',
'value d']]));
The JSONArray contains information for my select box, with a value -
label
pair.
But in my case, I want to make a new JSONArray filled with properties
from
my List of Groups.
So for example something like this:
for(Group group : ListGroup groups) {
jsonArray.put(group.getId, group.getName());
}
The problem is that a put operation only allows put(Object value) and
put(int index, Object value);
How can I add the group.getId and group.getName() as a value-label pair
to
the JSONArray?

Re: T5 + JSON + key name
Hi Sven,
I only see that they get the value by using the key name.
For example this:

data.name; //prints Violet.

But in my case, I don't know the key name, so I can't get the value.
Is there a way to get the key names of a JSON Object?

The only thing is that the order of groups in the select is gone.
I know for sure I put them in the correct order in the java jsonObject.
I think the var jsonObject = response.evalJSON(); or the for(var key in

ProductCategory category =
ProductCategory.getProductCategoryByName(value);
groups = characteristicDAO.findGroupsByProductCategory(category);

for (CharacteristicGroup group : groups) {

One option would be to add a change handler to the input field that

T5: JPA EntityManager + Tapestry Injection
I have added an JPA entity manager to my AppModule, in the same way this
is done for an HibernateSessionManager/Session in the tapestry-hibernate
project.
See the code below for some details.
I inject this entity manager with the @Inject into my DAO object.
@Inject
private EntityManager entityManager
In my DAO method I use the injected entityManager to build queries like
this:
entityManager.createNamedQuery(findProductsByCategory).setParameter(productCategory,
ProductCategory.Lamps).getResultList();
But the problem is that the entityManager is null. It seems that the
entityManager is not correctly injected into my DAO class.
Because when I use the entityManager directly in my Java Page class and
execute the same code, everything works well.
Java Page code:
public void onActivate() {
// this results in an null pointer exception.
products = productDAO.findAllByCategory(ProductCategory.Lamps);
//this is working.
products =
entityManager.createNamedQuery(findProductsByCategory).setParameter(productCategory,
ProductCategory.Lamps).getResultList();
}
What do I need to do so I can use my DAO classes?

How can I add multiple context values to an actionlink? For example a productId and a categoryId? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
T5: onActivate() called twice
Hi, I noticed that my onActivate() is called twice. I solved the problem by changing onActivate() into onActivate(Object[] parameters). Now it is only called once. But is this the way to do this or is there a better way? greetings, Leon - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5: onActivate() called twice
Hi Davor,
Indeed, I have a BasePage that implements the public void onActivate()
{}method.
In my subpage I also have implemented the public void onActivate() {}.
The code in onActivate() of my subpage is executed twice.
BASEPAGE:
public void onActivate() {
String pageName = resources.getPageName();
breadCrumbHolder.checkBreadCrumbForRemove(pageName);
}
SUBCLASS:
public void onActivate() {
logger.debug(OnActivate );
products = productDAO.findAllByCategory(ProductCategory.Books);
if (logger.isDebugEnabled()) {
logger.debug(Nr of products: + products.size());
}
}
This is the logging when I acces the page:
[DEBUG] Products OnActivate
[DEBUG] Products Nr of products:: 43
[DEBUG] Products OnActivate
[DEBUG] Products Nr of products:: 43

you have to be more specific,
same OnActivate method will not be called more than once in normal
circumastances,
but overriding onActivate from a base class I belive can cause this ...
some code would be useful.

RE: T5: onchange event from a select
I want to be able to update a second select, based on the value in the first select box. So I want to process it on the server-side, or with AJAX. Is there a way to catch the onchange event in my java page? JP Date: Sun, 23 Sep 2007 23:37:52 -0700 From: [EMAIL PROTECTED] To: users@tapestry.apache.org Subject: Re: T5: onchange event from a select Do you want it to be processed on the server side, or on the client side? For javascript, you should be able to just add an onchange attribute. If you want to add AJAX support, I'm not sure how to do that yet.

t:type=loop problem
I have a problem with the t:type=loop component in my Menu Component
Every link that is generated gets the id of the first Category. So the html
source looks like this:
ul
li
a href=/mercado/start.layout.menu.category/1 id=categoryCategoryA
| 1/a /li
/ul
ul
li a href=/mercado/start.layout.menu.category/1
id=category_0CategoryB | 70/a/li
/ul
ul
li a href=/mercado/start.layout.menu.category/1
id=category_1CategoryC | 110/a/li
/ul
Every categoryId is 1. (and it generates to much ul tags).
When I click a category link the application thinks I always click the first
category link.
This is what is in Menu.html
ul t:type=loop source=categories value=category
li
t:actionlink t:id=category context=${category.id}${category.name} |
${category.id}/t:actionlink
/li
/ul
And this is what is in Menu.java
@Inject
@Service(categoryService)
private CategoryService categoryService;
private Category category;
Object onActionFromCategory(Long categoryId) {
System.out.println(Category + categoryId + has been clicked);
categoryDetail.setup(categoryId);
return categoryDetail;
}
public CollectionCategory getCategories() {
return categoryService.getRootCategories();
}
public Category getCategory() {
return category;
}
public void setCategory(Category category) {
this.category = category;
}

Integration of T5 with the domain model
Just wanted to share how I hooked up T5 with my domain model.
I'm using jpa for persistence, so the thing I needed was injection of
the EntityManager into the objects providing access to my top level
domain objects.
And for just that simple IoC, Spring is way too overkill. Guice on the
other hand was quite nice for it.
I integrated it like this:
The access object
public class BlaBlaJPAQuery implements BlaBlaFinder {
@Inject //the guice inject annotation
private EntityManager _entityManager;
//Code...
}
the JPAUtil
public class JPAUtil implements ProviderEntityManager {
private static final EntityManagerFactory _entityManagerFactory;
private static ThreadLocalEntityManager _entityManagerContainer;
static {
_entityManagerFactory =
Persistence.createEntityManagerFactory(POB);
_entityManagerContainer = new ThreadLocalEntityManager();
}
public static void createEntityManager() {
_entityManagerContainer.set(_entityManagerFactory.createEntityManager())
;
}
public static void closeEntityManager() {
EntityManager entityManager = _entityManagerContainer.get();
entityManager.close();
}
public EntityManager get() {
return _entityManagerContainer.get();
}
}
Another filter before the T5 filter that does this:
public void doFilter(ServletRequest request, ServletResponse
response, FilterChain filterChain) throws IOException, ServletException
{
try {
JPAUtil.createEntityManager();
filterChain.doFilter(request, response);
} finally {
JPAUtil.closeEntityManager();
}
}
The Guice module:
public class POBGuiceModule extends AbstractModule {
public void configure() {
bind(EntityManager.class).toProvider(JPAUtil.class);
}
}
And the T5 module:
public class POBTapestryModule {
private static final Injector _injector;
static {
_injector = Guice.createInjector(new Module[] { new
POBGuiceModule() });
}
@Lifecycle(value=perthread)
public static BlaBlaFinder buildBlaBlaFinder() {
return _injector.getInstance(BlaBlaJPAQuery.class);
}
}
And offcourse the page:
@Inject //T5 inject annotation
private BlaBlaFinder _blablaFinder;

load modules with jettylauncher without a jar
Ok, I'm doing something wrong here. I'm working on a T5 project where I have a T5 module. I made a manifest file which is in the META-INF folder that is in the classpath (m2 resource folder, that is added as a source folder under eclipse). I'm running jettylauncher to test the project, but the module isn't loaded by Tapestry. What am I doing wrong? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: load modules with jettylauncher without a jar
Thanks for the quick reply. I resolved it by adding a .jar with only the manifest file as library in eclipse. I have an m2 project setup with inheritance where all code (and then with manifest file) is built into jars anyway which are then included in the war. So for the integration and test servers I didn't have a problem anyway. The 'manifest jar' is just for running jettylauncher and is only present in that environment. -Oorspronkelijk bericht- Van: Howard Lewis Ship [mailto:[EMAIL PROTECTED] Verzonden: woensdag 11 april 2007 16:16 Aan: Tapestry users Onderwerp: Re: load modules with jettylauncher without a jar Servlet class loaders do not look for META-INF/Manifest.mf inside the WAR. I believe you could place it WEB-INF/classes/META-INF/Manifest.mf. From what you describe, I'm not sure that the manifest file is showing up in the right place. I would not rely on the manifest approach for a web application, but instead rely on how T5 loads the application module, as demonstrated in the quickstart Maven archetype.
