Re: Jasper Reports integration module-GSOC 2010
Welcome on this list Charith. So what exactly are you planning to do? What will your integration look like? Please discuss your more concrete ideas. Just saying "I'll do a JasperReports integration because JasperReports is nice" just is not enough. You should think of how the integration is supposed to work, what components you are planning to implement and think of what problems you might encounter on your way.

Embed an installation application in your tapestry 5 application
Hi, For Tapestry developers who are interested in a easy way to build a configuration wizard for their Tapestry 5 applications, we have started a new project called 'tapestry5-installer' that allows to load the 'real' application after the configuration is finished. This solution is currently under test with wooki. http://github.com/spreadthesource/tapestry5-installer/ http://spreadthesource.com/2010/04/create-your-web-installation-wizard-for-your-tapestry-5-applications/ -- Regards, Christophe Cordenier.

AjaxFormLoop and Radio button
Hi, I'm trying to use an AjaxFormLoop for rows that have a textfield and a radio button. Outside the AjaxFormLoop I have a RadioGroup component to "contain" all the Radio. But when I click the addRowLink I have an error because RadioContainer is not in the environment (which is normal because RadioGroup doesn't get rendered in the addRow event...). Is there a way to accomplish this or a RadioGroup with its Radio MUST be rendered all together?

Zone updating / caching
Is there a convenient way of ensuring a zone updates from the server upon browser back or is something hackish in onLoad required? I found this previous related query below but don't want to completely abandon the browser cache for multiple pages / image heavy areas etc.. http://www.nabble.com/T5---Zone-update-annoyance.-tp22680692p22708410.html The context is a menu component that can be used in many places that references a variable held at SessionContext to get an idea of where it is in the menu hierarchy. Is there something that can be set at block / zone level that will force a zone show / update / etc? Would be grateful to head how other users have worked around this. Regards, Jim.

[Tapestry Central] Meta-Programming Java with Tapestry
A significant amount of what Tapestry does is meta programming: code
that modifies other code. Generally, we're talking about adding
behavior to component classes, which are transformed as they are loaded
into memory. The meta-programming is the code that sees all those
annotations on methods and fields, and rebuilds the classes so that
everything works at runtime.
Unlike AspectJ, Tapestry does all of its meta-programming at runtime.
This fits in better with live class reloading, and also allows for
loaded libraries to extend the meta-programming that's built-in to the
framework.
All the facilities Tapestry has evolved to handle meta-programming make
it easy to add new features. For example, I was doing some work with
the Heartbeat enviromental object. Heartbeat allows you to schedule
part of your behavior for "later". First off, why would you need this?
A simple example is the relationship between a Label component and a
form control component such as TextField. In your template, you may use
the two together:
The for parameter there is not a simple string, it is a component id.
You can see that in the source for the Label component:
@Parameter(name = "for", required = true, allowNull = false,
defaultPrefix = BindingConstants.COMPONENT) private Field field;
Why does for="email" match agains the email component, and not some
property of the page named email? That's what the defaultPrefix
annotation attribute does: it says "pretend there's a component: prefix
on the binding unless the programmer supplies an explicit prefix."
So you'd think that would wrap it up, we just need to do the following
in the Label code:
writer.element("label", "for", field.getClientId());
Right? Just ask the field for its client-side id and now all is happy.
Alas, that won't work. The Label component renders before the
TextField, and the clientId property is not set until the TextField
renders. What we need to do is wait until they've both rendered, and
then fill in the for attribute after the fact.
That's where Heartbeat comes in. A Heartbeat represents a container
such as a Loop or a Form. A Heartbeat starts, and accumulates deferred
commands. When the Heartbeat ends, the deferred commands are executed.
Also, Heartbeats can nest.
Using the Heartbeat, we can wait until the end of the current heartbeat
after both the Label and the TextField have rendered and then get an
accurate view of the field's client-side id. Since Tapestry renders a
DOM (not a simple text stream) we can modify the Label's DOM Element
after the fact.
Without the meta-programming, it looks like this:
@Environmental private Heartbeat heartbeat; private Element
labelElement; boolean beginRender(MarkupWriter writer) { final Field
field = this.field; decorator.beforeLabel(field); labelElement =
writer.element("label"); resources.renderInformalParameters(writer);
Runnable command = new Runnable() { public void run() { String fieldId
= field.getClientId(); labelElement.forceAttributes("for",
fieldId, "id", fieldId + "-label"); decorator.insideLabel(field,
labelElement); } }; heartbeat.defer(command); return !ignoreBody; }
See, we've gotten the active Heartbeat instance for this request and we
provide a command, as a Runnable. We capture the label's Element in an
instance variable, and force the values of the for (and id) attributes.
Notice all the steps: inject the Heartbeat environmental, create the
Runnable, and pass it to defer().
So where does the meta-programming come in? Well, since Java doesn't
have closures, it has a pattern of using component methods for the same
function. Following that line of reasoning, we can replace the Runnable
instance with a method call that has special semantics, triggered by an
annotation:
private Element labelElement; boolean beginRender(MarkupWriter writer)
{ final Field field = this.field; decorator.beforeLabel(field);
labelElement = writer.element("label");
resources.renderInformalParameters(writer); updateAttributes();
return !ignoreBody; } @HeartbeatDeferred private void
updateAttributes() { String fieldId = field.getClientId();
labelElement.forceAttributes("for", fieldId, "id", fieldId + "-label");
decorator.insideLabel(field, labelElement); }
See what's gone on here? We invoke updateAttributes, but because of
this new annotation, @HeartbeatDeferred, the code doesn't execute
immediately, it waits for the end of the current heartbeat.
What's more surprising is how little code is necessary to accomplish
this. First, the new annotation:
@Target(ElementType.METHOD) @Retention(RUNTIME) @Documented @UseWith( {
COMPONENT, MIXIN, PAGE }) public @interface HeartbeatDeferred { }
The @UseWith annotation is for documentation purposes only, to make it
clear that this annotation is for use with components, pages and
mixins ... but can't be expected to work elsewhere, such as in services
layer objects.
Next we need the actual meta-programming code. Component
meta-programming is accomplished by classes that implement the
ComponentCl

Re: ServiceOverride recursion issue - T5.2
FWIW, when I got back to the override issue after a few days of
unrelated work (mostly expanding the registry with a few unrelated
services), suddenly this started to work:
@SubModule( { ServicesModule.class })
public class AppModule {
public static void contributeServiceOverride(
MappedConfiguration, Object> configuration,
@Local ISiteService siteServiceOverride) {
configuration.add(ISiteService.class, siteServiceOverride);
}
public static ISiteService buildXyz(IDataService dataService) {
return new MySiteService(dataService);
}
}
A different order of service loading or a typo in the old build method
name... Hard to say now.

Ok, not very specific, but I found what you are referring to.
Unfortunately @Local annotation on the override itself doesn't help.
It seems like I have to define local versions of all dependencies,
which is something I'd really like to avoid for stateless services.
A similar structure of services worked with Hivemind and T4, so I
wonder if there's a way to make it work in T5 as well? (other than
binding concrete service implementation at the app level to avoid
overrides)

I have tried the developer tools but only came to the conclusion that something is leaking memory, which didn't get me very far. I also spent some days with trying tapestry 5.2, hacking tapestry.js, trying to rephrase bits of code that looked suspicious to me, but without much success. Today I also tried the new prototype RC, but the results were comparable to the 1.6.1 one. Today I stumbled upon a ticket in the prototype bugtracker [1], and after applying parts of the appended patch and playing around, I am now sure, that it is definitely related. Unfortunately, that patch increases the CPU usage considerably, mostly due to the CACHE=CACHE.without(element) line. I haven't yet made up my mind whether to completely remove the CACHE parts (which seem to be needed for IE only, which I don't care about for that project) or spend more time to find a better way, but I thought I'd share my findings.

Re: submit form on Safari and Opera doesn't work
You're complicating your implementation beyond needed. What you're trying is to do two requests in sequence: one to submit the form, other to handle an event. This is very error-prone, as it relies on the ordering of the arrival of the. Just use a LinkSubmit: the form will be submitted and the selected event will be triggered in the same request. Well, LinkSubmit didn't works for me. But you are right that my problem was in ordering of click events. So I got rid off action on click and all my logic I put to "submitForm" handler. Type of action I send as a hidden field. It starts finally work even in Safari and Opera.

- *Proyect*(idProyect, name, city,)
- *Member*(idMember, idUser, idProyect, ...)
I want to* make a select using user.name as label and member.idMember as
value.*
I took a look to:
http://wiki.apache.org/tapestry/Tapestry5HowtoSelectWithObjects
Now, I have the following:
- *MemberCTO(idMember, name)*, with a public Constructor, and getters &
setters for idMember, name
--
On the page (.tml) I have:
--
On the page (.java) I have
...
@Persist @Property private memberCTO memberCTO;
private GenericSelectModel membersCTO;
public GenericSelectModel getmembersCTO(){
return membersCTO;
}
void setupRender() {
membersCTO = new GenericSelectModel
(memberDao.findUsersInProyect( fase.getProyecto().getIdProyecto()),
memberCTO.class, "name", "idMember", _access);
}
The source code of GenericSelectModel was obtained from:
http://wiki.apache.org/tapestry/Tapestry5HowtoSelectWithObjects
I try to load the page, and I get an error (you can see it at the end).
I debugged the code, and I can say:
- membersCTO contains an ArrayList with the data obtained form
the DB.
- GenericSelectModel, establish (at the Constructor):
- idFieldAdapter...: PropertyAdarptedImpl. name='idMember'
- labelFieldAdapter: PropertyAdarptedImpl. name='name'
(I think its correct)
- List getOptions() {} (Inside GenericSelectModel class)
for (T obj : list) {
optionModelList.add(new OptionModelImpl(nvl(labelFieldAdapter.get(obj)),
obj));
}

Particularlly: labelFieldAdapter.get(obj) doesnt work:

problems with client validation Internet Explorer 8 - no background images
Hello, I have set the form parameter: clientValidation=true and defined validations for the fields, like this:txtRowsPerPage-required-message=You must provide a value for: rows per page! when the validation fails the following div appears:You must provide a value for: rows per page! Using Internet Explorer 8: only the message appears no background images. I guess I have to redefine one or more of the following css entries:html > body div.t-error-popup spanhtml > body div.t-error-popupdiv.t-error-popup div.t-error-popup span Could somebody write me which and how exactly? thanx in advance Izolda
Re: Unit testing with tapestry 5.1 and spring

It looks annoying but it is kind-of useful because it makes sure you are testing with a context value and helps avoid your features working when there is no context and then breaking when there is one (only likely to happen for low-level URL mangling features though). I have looked at connecting the Spring layer into tests and it is quite hard to do. The tapestry-spring integration doesn't provide hooks that allow it to work outside a web container - it could do with some refactoring to allow this :-) In case it helps, here's what my projects are doing: we do acceptance testing using Fitnesse with a full Spring container and the tests start just below the web UI. Then we unit test Tapestry components with Testify and integration test the whole lot with a small number of Selenium tests. We also use Selenium for any rich UIs with Ajax or Javascript.
