Re: T5:how to inject slf4j service?
I checked slf4j sourcecode,there has a Logger interface
implement:org.slf4j.impl.Log4jLoggerAdapter
but how to bind them together and make a inject? need improve
AppModule's function?
I don't know why tapestry hadn't done it for user? need help too...

Logging of Tapestry Components and Pages
Tapestry makes extensive use of SLF4J to log details about the
creation and operation of your page and component classes.
The default configuration for logging uses Log4J as the logging
toolkit, though this can be changed.
but this can be changed page link is invalid.
somebody help me?give me example to fire a light in my darkness. :)

Re: Accessing page context from a component
Chakra words reminds me of the interesting idea for components to have their independent activation context. That page is not aware of. In this case the component encapsulates the knowledge about specific url parameters that it needs. And can be reused on different pages without altering them. For example imagine a custom pager component that needs parameter pageNum. I use a somewhat similar solution using @Environmental inside Mixins that stores data in request parameters.

public Object onLeague(Object[] in) {

JSONObject json = new JSONObject();
json.put(content,);
json.put(script, alert('hi'););
return json;
}
and I'm alwasy getting an zone-update which shows me the json-onject-literal

What's wrong there?

Re: Avoiding recursion detection in ajax situations.
Ok, got it working. The end result was that I created the following in order to do this: 1) A custom service which I use to retrieve the block from the injected page. While retreiving the block, I have to tell this service what the real form component should be, essentially. 2) An outbound url rewriter, that uses that custom service to convert form links pointing to the injected page to the page doing the ajax. 3) A mixin which setupRender/cleanupRender wraps AbstractField. WHat I do is I slip in my own FormSupport into environment for any AbstractField (the most base class of form fields), so that I can intercept the store() method, in which I return the ajax page's component instead of the injected pages component, so that t:formdata hidden field 'points' to the ajax page's form and not the injected one. Not alot of code, but a ton of work and investigation. ownedthx wrote: I tried url rewriting the outbound action attribute to match the component form, instead of the form from the injected page. It causes the event to raise now in the right form... but all the form field data are sent to the form in the injected page, because that big nasty hidden input field that tapestry injects in ever form, once decoded, tells Tapestry to send the form field data to that other form. I always wondered what that hidden data was doing. I guess, in this circumstance, I can not use the field in my own form (which is null) but instead decode the hidden field data in my component using ClientDataEncoder, retrieve the form from the injected page by ID, and then grab it's values... Seth Robert Zeigler wrote: The problem is that even though there is no recursion in the / rendering/, per se, there is recursion in the structure. All recursive routines (and even having A = B = A is a recursive structure) have to have a stop condition; the problem is that the stop condition for rendering is only known when rendering, and tapestry can't know it when building the /structure/ of the page. Ergo, the strict structure requirements. I think you were on the right track with the injected page trick, although I would probably have taken a slightly different track, using component source to retrieve the page and corresponding component. Also, if there's a Form in A, and your including A = B = A, does that mean you have a nested form?? With a bit more information about the specific details of what you're trying to accomplish, the list might be able to propose a solution that will work for you.

I guess, though, that the zone has to have my component defined (which however would cause the recursion detection to fire), because I get an error on initial page load, complaining that the zone does not define the component. At this point, I think this is a bug in Tapestry, because the recursion detection logic shouldn't necessarily use what's in t:block. I understand the whole reason it's there is to avoid infinite loops, but at the same time I should be able to do this, since I'm not actually doing recursion.

However, there is a situation where, say in component A's template, that I want to define a block which has a reference to component A--but I'll only call that component in a Zone update via Ajax. In other words, there isn't actually recursion going on, because in a full page refresh, the block isn't rendered, and when the zone is updated with Ajax, the component is rendered but that's OK because it's parent isn't being rendered. Regardless, Tapestry get's mad, warning me about recursion if I put that block in the page. Ok, fine, so I try to get around that. I have an approach that works ... almost: I made a 'worker' page, which has nothing but a block defined--the block with the component A. I then inject that page into my component, (using @InjectPage) and then on Ajax request to my component, I use a public getter to retrieve the block from this injected page, and return that. I'm having some sort of issue though; if that block from the injected page contains a form, and I then submit that form, tapestry throws

[Tapestry Central] No Fluff Just Stuff Seattle Roundup
It was a huge pleasure to be speaking at a No Fluff Just Stuff
conference again, it's been much too long. This was a good show with a
lot of folks coming down from Vancouver, BC to attend.
This was an odd show for me, as we didn't do any Tapestry talks at all.
However, all three of my talks (an introduction to Cappuccino, and two
talks on Clojure) were well attended, with good questions and some fun
discussions between sessions. I'm looking forward to doing these same
sessions, with a number of improvements, in the Spring when NFJS starts
back up.
Interestingly, I was busy writing Clojure code almost continuously in
the back row of other speaker's sessions ... but this didn't stop me
from appreciating Scott Davis's great talks on Grails, and
on deconstructing Web 2.0. Also, I had a lot of interaction with
Brian Goetz (are all web application's broken). As usual, as soon as
you mix Java with concurrency, it's a bit sobering. Tapestry helps
here, but is not a complete panacea against some of the nightmare
scenarios that may become more commonplace as the number of CPU cores
increases.
I'm getting more adept at advanced Clojure; I've been busy adapting the
concept of parameter destructuring to pulling data out of the request
path and query parameters.
(defaction increment-count {:path count/increment} [env]
[count :int] ; destructure the value after /increment as an integer
(send-redirect env (link env show-counter [(inc count)])))
This defines a Cascade action, mapped to the count/increment path. A
number is expected to follow (i.e., /count/increment/4) and the job of
this action is to increment that value and redirect the user to the
show-counter view.
Cascade actions are still functions, thus the [env] (Cascade actions
always take a single parameter, a map called the environment that
provides access to Cascade values as well as Servlet API objects).
The path destructuring follows: [count :int] which destructures the
first extra path value as an integer. There's a number of built-in
parsers referenced by keywords such as :int, or you can supply a
function that takes a string and returns a value. If another pair of
values is given, that applies to the next value in the path.
I'm finding this a pretty elegant way to express this secondary aspect
of mapping URLs to view and actions; there's additional syntax for
destructuring query parameters instead of path values. I may extend
this further, to handle default values for missing terms in the path.
I try to capture some of this in my Clojure talks; the idea of growing
the language up, adding the new features you need. From one
perspective, this is just a domain specific language, but in the Lisp
world, that concept is so deeply entrenched that there isn't even a
word for it beyond programming. This is one part of the overall
Clojure picture that gets me very excited, and I'm continuing to
struggle with how to express this to people for whom even the Lisp
syntax is alien and off-putting.

I don't know how you would get the component tree.
But, if the annotation was in a page, I would implement a
ComponentClassTransformer. This is an example that I hope it gives you a
clue:
public class TapestrySecurityWorker implements
ComponentClassTransformWorker {
public void transform(ClassTransformation transformation,
MutableComponentModel model) {
if (transformation.getAnnotation(NeedsLoggedInUser.class) !=
null) {
model.setMeta(TapestrySecurityConstants.NEEDS_LOGGED_IN_USER_METADATA_KEY,
true);
}
}
}
The important trick here is the MutableComponentModel.setMeta() method.
Then, in a dispatcher, I can check the meta information:
String pageName = extractPageName(request);
if (pageName != null) {
final ComponentModel pageModel =
componentModelSource.getPageModel(pageName);
final String loggedInMetaValue =
pageModel.getMeta(TapestrySecurityConstants.NEEDS_LOGGED_IN_USER_METADATA_KEY);
...
}
private String extractPageName(Request request) {
String pageName = null;
final ComponentEventRequestParameters componentEventParameters =
linkEncoder.decodeComponentEventRequest(request);
if (componentEventParameters != null) {
pageName = componentEventParameters.getContainingPageName();
}
if (pageName == null) {
final PageRenderRequestParameters pageRenderParameters =
linkEncoder.decodePageRenderRequest(request);
if (pageRenderParameters != null) {
pageName = pageRenderParameters.getLogicalPageName();
}
}
return pageName;
}

Re: T5:how to inject slf4j service?
You need an implementation of slf4j, there are a lot. I use
slf4j-log4j12.1.5.2 (it's a bridge between slf4j and log4j)
Check this blog:

Re: Obtaining a reference to the component tree of a page while Dispatching
Thiago,
Thanks for your quick response. Security checking on the page level is
all fine and works great. It is good to see that my implementation
overlaps yours a lot. (Difference is that I don't use the setMeta, but
check for the annotation in the Dispatcher itself)
I was hoping to be able to actually annotate a component and reject page
access based on the most restricting annotated component on the page.
I'll keep trying. any further pointers would be appreciated.
Thanks,
Joost

Hi,
Hi!
I am looking for a way to get a hold of all components Class'es on a
page while in a dispatcher. I want to know if any of the components
on the page are annotated with my custom @SecuredContent annotation
but have no clue how to figure out what components are loaded on a
page when I only have access to the page.
I don't know how you would get the component tree.
But, if the annotation was in a page, I would implement a
ComponentClassTransformer. This is an example that I hope it gives you
a clue:
public class TapestrySecurityWorker implements
ComponentClassTransformWorker {
public void transform(ClassTransformation transformation,
MutableComponentModel model) {
if (transformation.getAnnotation(NeedsLoggedInUser.class) !=
null) {
model.setMeta(TapestrySecurityConstants.NEEDS_LOGGED_IN_USER_METADATA_KEY,
true);
}
}
}
The important trick here is the MutableComponentModel.setMeta()
method. Then, in a dispatcher, I can check the meta information:
String pageName = extractPageName(request);
if (pageName != null) {
final ComponentModel pageModel =
componentModelSource.getPageModel(pageName);
final String loggedInMetaValue =
pageModel.getMeta(TapestrySecurityConstants.NEEDS_LOGGED_IN_USER_METADATA_KEY);
...
}
private String extractPageName(Request request) {
String pageName = null;
final ComponentEventRequestParameters componentEventParameters =
linkEncoder.decodeComponentEventRequest(request);
if (componentEventParameters != null) {
pageName = componentEventParameters.getContainingPageName();
}
if (pageName == null) {
final PageRenderRequestParameters pageRenderParameters =
linkEncoder.decodePageRenderRequest(request);
if (pageRenderParameters != null) {
pageName = pageRenderParameters.getLogicalPageName();
}
}
return pageName;
}
linkEncoder is an instance of the ComponentEventLinkEncoder service.

Re: New Tapestry Website - Final review
I find that dynamic menus that slide down (or in any direction) slow me down. You need to wait a part of a second or maybe even one whole second til it slides, while with a static menu I would already be inside the page I wanted. But this is true only if everything can be easily fitted on one page, so that's why I would recomment to have an automatically updated sitemap. For me, sitemaps are a nice solution for fast way of navigation. You need one click to open it and after a short glance you will see what you need and in which context it is located.

Concerned about the future of Tapestry
Hi Howard, All The following sound bites seem to paint a pretty bleak future for Tapestry. 1) Interestingly, I was busy writing Clojure code almost continuously in the back row of other speaker's sessions .I've been busy adapting the concept of parameter destructuring to pulling data out of the request path and query parameters. - HLS, today. Writing what sounds like the groundwork for a new web application framework, presumably better than Tapestry. 2) I'm using my improved freedom to pursue other important technologies * beyond* Tapestry, such as Clojure, Cappuccino, and CouchDB - HLS, August 27 Despite what appears to be a healthy community, a solid code base and set of hard working committers I am still inclined to believe that the driving force behind the innovation in Tapestry is still you Howard. In my mind your move to different technologies signifies a loss of faith in Java and implies a sense of frustration with the limits of what is possible with T5. Can anyone set my mind at ease with some real facts about the future of Tapestry? I have invested a year or more in learning the framework and applying what I know to creating a web application with it but as a developer I need to know that my code won't just be another rewrite waiting to happen. The alternative, JSF, may be clunky but at least I can be certain that it will be around and evolving in 5 years time. Regards Steve

I have invested a year or more in learning the framework and applying what I know to creating a web application with it but as a developer I need to know that my code won't just be another rewrite waiting to happen. Several years ago I posted something about Ruby and there was a flurry of posts: Is Howard abandoning Java? Guess what ... I didn't. I'm committed to Tapestry even beyond what it represents as a revenue stream. I expect to see more releases like 5.1 ... compatible, with new features that seamlessly plug into existing applications. More importantly, I want to make the documentation better (in book form, and online). In fact, if I never committed another line of code to Tapestry but JUST wrote a definitive book on it, that would do more to extend the life and acceptance of Tapestry than anything else I could possibly do! The alternative, JSF, may be clunky but at least I can be certain that it will be around and evolving in 5 years time. Yes, they may have gotten through one round of improvement by then :-) Regards Steve Steve, I'm afraid you misunderstand how innovation occurs ... it doesn't happen by locking someone in a basement so they can focus on only one thing. Innovation comes from learning different ideas, different languages, different technologies and expanding your mind around them. The Pragmatic Programmers emphasize learning a new language every year and I like to learn a new technology more often than that. Many of the innovations you see in Tapestry are ideas that came from other areas, in other guises. So don't worry, I'm going to have my fingers in a few different pies ... and I'm going to learn new things and adapt them back into Tapestry.

---Service Builder Methods---
Sometimes just instantiating a class is not enough; there may be
additional configuration needed as part of instantiating the class.
Tapestry 5 IoC's predecessor, HiveMind, accomplished such goals with
complex service-building services. It ended up being a lot of XML.
T5 IoC accomplishes the same, and more, using service builder methods;
module methods that construct a service. A typical case is when a
service implementation needs to listen to events from some other
service:
public static TranslatorSource
buildTranslatorSource(ComponentInstantiatorSource
componentInstantiatorSource,
ServiceResources resources)
{
TranslatorSourceImpl service =
resources.autobuild(TranslatorSourceImpl.class);
componentInstantiatorSource.addInvalidationListener(service);
return service;
}
Module methods prefixed with build are service builder methods. The
service interface is defined from the return value (TranslatorSource).
The service id is explicitly TranslatorSource (that is, everything
after build in the method name).
Here, Tapestry has injected into the service builder method.
ComponentInstantiatorSource is a service that fires events.
ServiceResources is something else: it is a bundle of resources
related to the service being constructed ... including the ability to
instantiate an object including dependencies. What's great here is
that buildTranslatorSource() doesn't need to know what the
dependencies of TranslatorSourceImpl are, it can instantiate the class
with dependencies using the autobuild() method. The service builder
then adds the new service as a listener of the
ComponentInstantiatorSource, before returning it.

related to the service being constructed ... including the ability to
instantiate an object including dependencies. What's great here is
that buildTranslatorSource() doesn't need to know what the
dependencies of TranslatorSourceImpl are, it can instantiate the class
with dependencies using the autobuild() method. The service builder
then adds the new service as a listener of the
ComponentInstantiatorSource, before returning it.

Re: T5:how to inject slf4j service?
I got the answer! It's so easy...thank all of my helpers and opensource!
my problem's solution:add this function in AppModule class:
public Logger buildLogger(final Logger log){
return log;
}
I'd read this
article:http://java.dzone.com/news/tapestry-5-ioc-binding-and-bui,and
learned what's the secret key in there:
---Service Builder Methods---
Sometimes just instantiating a class is not enough; there may be
additional configuration needed as part of instantiating the class.
Tapestry 5 IoC's predecessor, HiveMind, accomplished such goals with
complex service-building services. It ended up being a lot of XML.
T5 IoC accomplishes the same, and more, using service builder methods;
module methods that construct a service. A typical case is when a
service implementation needs to listen to events from some other
service:
public static TranslatorSource
buildTranslatorSource(ComponentInstantiatorSource
componentInstantiatorSource,
ServiceResources resources)
{
TranslatorSourceImpl service =
resources.autobuild(TranslatorSourceImpl.class);
componentInstantiatorSource.addInvalidationListener(service);
return service;
}
Module methods prefixed with build are service builder methods. The
service interface is defined from the return value (TranslatorSource).
The service id is explicitly TranslatorSource (that is, everything
after build in the method name).
Here, Tapestry has injected into the service builder method.
ComponentInstantiatorSource is a service that fires events.
ServiceResources is something else: it is a bundle of resources
related to the service being constructed ... including the ability to
instantiate an object including dependencies. What's great here is
that buildTranslatorSource() doesn't need to know what the
dependencies of TranslatorSourceImpl are, it can instantiate the class
with dependencies using the autobuild() method. The service builder
then adds the new service as a listener of the
ComponentInstantiatorSource, before returning it.
