Re: [T5.1] Obtaining The Page Name In A MarkupRendererFilter
Hello,
Following a suggestion from a fellow T5 user (cheers Nicolas!) I've
changed my page name injecting strategy. I now have a
ComponentClassTransformWorker which adds a Mixin to every Page
component. This Page Mixin (in the afterRender() method) then injects
the page name as a comment in the Document model.
This has the benefit of injecting the name of the rendered page as
oppose to the name of the requested page. The important difference is
that on error pages (http 404 and 500) I now inject the names of the
error pages and not what the user originally asked for.
What I'd like to know now, is there a nice way, in the
ComponentClassTransformWorker to check if I'm transforming a page?
Both of the following work, but neither seem particularly pleasant:
@Inject
private ComponentClassResolver resolver;
try {
resolver.resolvePageClassNameToPageName(transformation.getClassName());
} catch (IllegalArgumentException e) {
// not a page... goodbye!
return;
}
... or...
if (!transformation.getClassName().contains(.pages.))
// not a page... goodbye!
return;
Any ideas?
Cheers,
Steve.

Re: [T5.1] Obtaining The Page Name In A MarkupRendererFilter
Yeah, exceptions are expensive to create and throw and never should
really be caught as part of the normal flow code (*). The example was
really just an ineffective way of pointing out I know the
ComponentClassResolver exists and I know it holds map of page names to
page class names.
The thing is, it always assumes the input strings (page / component /
mixin names) to be valid but doesn't provide a way for me to check
them before hand. I was just wondering if there's some other service
or transform method I've overlooked.
use this one, but changing contains by
startWith(full.name.of.package.pages.);
Nice, but I'm turning it in to a component for reuse. Besides, no
one's ever going to put a pages subpackage in their component
package! (Sorry, what's that you say about 637K and Bill Gates?)
Steve.
(*) speaking of which, has anyone ever created their own Integer
parser? Or do we all just catch the NumberFormatException?

Btw, i responded by mistake directly to you instead of responding to the

I may use this one, but changing contains by
startWith(full.name.of.package.pages.);
But the tradeoff is that you will not transform pages outside the scope of
your project (such as ExceptionReport)
Any ideas?

Re: Noob problem with Guessing Game tutorial
Not sure what the current T5 deal is with putting .tml files in the
WEB-INF, but I'm certain it's not recommended.
Again, as Sergey and I have suggested, place your .tml files in the
same package as your java / class files.
With your current maven setup, that would be:
src/main/resources/org/apache/tapestry5/tutorial/pages

you must provide a matching event handler method in the component or in

Can someone tell me what I am doing wrong?

Re: Noob problem with Guessing Game tutorial
Hi Phil, Now you've made me do the tutorial... (D'Oh) and yeah, it's not quite as accurate as I expect it once was. But fundamentally, the principles are sound. So again, starting from scratch, I generate the archetype. For the record, I'm using Maven 2.2.1 (as given by mvn -version) and by default (i.e. pressing [enter]) it creates the tutorial in the package : org.apache.tapestry : so we'll go with this. Now org.apache.tapestry is important, it means all your page code and your page templates go in to org.apache.tapestry.pages So your Index.java and Guess.java go in to: /src/main/java/org/apache/tapestry/pages and Index.tml and Guess.tml go in: /src/main/resources/org/apache/tapestry/pages The important thing is, that once compiled, all your .class files and your .tml files end up in the same place. Following our example this would be: /target/classes/org/apache/tapestry/pages Note how org.apache.tapestry.pages is used throughout. I cut'n'paste'ed the java files from the tutorial and they give the wrong java package of org.apache.tapestry5.tutorial.pages but follow the eclipse hint to change it to org.apache.tapestry.pages The tutorial .tml files are fine. The generated web.xml is fine also, so no need to touch that. Despite the tutorial saying otherwise I would stick to using mvn jetty:run for now to prevent further complicating your set up. (In fact I use nothing else and still get live class re-loading but my setup is probably a little more advanced.) In fact, start using mvn clean jetty:run just to make sure no stray class files are hanging around. And that's it - it works on my machine! From there it's all about cut'n'pasting bits of code and not whole pages. And once everything is in the correct directory it should largely, just work. By the way, org.apache.tapestry is not a special package, you can use what ever you want - just make sure everything is the same. i.e. if use the package foo.bar.t5 then .java files go in: /src/main/java/foo/bar/t5/pages .tml files go in: /src/main/resources/foo/bar/t5/pages so your .class and .tml files end up in: /target/classes/foo/bar/t5/pages and make sure the tapestry.app-package param-value in your web.xml is set to foo.bar.t5 I don't think I can say much more than that. But to be honest, if Java, Eclipse, Maven and Web Apps are all new to you, then I suspect you're in for rough ride and a steep learning curve whatever platform you try out. Good luck! Steve.

Each time I re-create my project, I follow the tutorial and actually use the exact command you specified. (Discovered the create error in the tutorial (deprecated function) after a couple of hours). It creates a project for me and going to the URL works great. I see the time-of-day function and clicking on refresh works great. I continue to follow the tutorial example and import the new, working project into my Eclipse. (that's when the .tml files get separated from the .java files). Going to the URL at that point reveals the index.tml page and all looks good until you click the link. Nothing works beyond that. I checked my web.xml and did have tutorial instead of tutorial5, however, making the change ended up with the same error, but gave me a new branch in my directory along with two new .class files. I'm losing steam... I feel like I should not proceed to other samples, examples, if I can not get this very simple one working. I'm considering dropping this altogether and giving other paradigms a try. I've seen appFuse and echo Web but was under the impression that tapestry was more settled and would be easier to learn.

Re: URLRewriting and tapestry.force-absolute-uris
Hi Christian, If you are just looking to change incoming legacy requests and don't care about URLs once the user has entered the system, have a look at: Url Rewrite Filter - http://tuckey.org/urlrewrite/ It's a servlet filter than alters the URL before Tapestry sees it, allowing you to convert legacy URLs into T5 friendly ones. It supports Forwards Redirects, regex and wildcards and I think even lets you run java code for more complicated transformations.

[T5.1] Obtaining The Page Name In A MarkupRendererFilter
Hello, I'm looking at ways to automatically insert the name of the page being rendered into each page (so my selenium tests can check the correct page was finally rendered). This was done using a component I placed on each page but I'm looking for a more elegant solution. I've tried contributing a MarkupRendererFilter to add my tag via writer.getDocument(). The only way I know to get hold of the current page name is through ComoponentResources.getPageName(). But ComoponentResources wasn't in the Environment and doesn't seem to be Shadowed either. Is MarkupRendererFilter the right object to contribute for this? And if so, where would I get the current Page name from?

Re: AjaxFormLoop: property changes have no effect
Excellent - I'm really happy I found this email for I to, fell into
the same trap.
I entered the world of ValueEncoders after playing with Field
Translators and TypeCoercers and thought maybe they did the same
thing. I also (wrongly) thought that as I supplied the AjaxFormLoop
with a source List, Tapestry would be able to back track through the
list and set the properties for me (much the same as it read them in
the first place).
Anyhow, it all works now and I just thought I'd keep this thread
relevant in case anyone else has the same problem.

How do I advise the ClassNameLocator service?
If I add the following advice method to my AppModule ...
@Match(*)
public static void adviseEverything(MethodAdviceReceiver receiver) {
System.out.println(receiver.getInterface());
}
Only the following interfaces are advised ...
interface org.apache.tapestry5.ioc.ObjectProvider
interface org.apache.tapestry5.services.AliasManager
interface org.apache.tapestry5.services.ApplicationInitializer
interface org.apache.tapestry5.services.UpdateListenerHub

interface org.apache.tapestry5.services.RequestGlobals
interface org.apache.tapestry5.services.LocalizationSetter
interface org.apache.tapestry5.services.ComponentSource
interface org.apache.tapestry5.internal.services.RequestPageCache
I can debug and step into the ClassNameLocator so I know it's been
created but I'm not given an opportunity to override its return value.
To give context, I am trying to use tapx-templating to generate
customer receipts (which are exported into pdf files via Flying Saucer
and iText).
It all works brilliantly when run from unit tests but fails miserably
when I make the same call from within an Eclipse RCP application. It
fails due to the ClassLoader of the RCP app returning URLs in the form
of :
bundleresource://1/com/bushmasters/admin/templating/pages/
which the Tapestry ClassNameLocator service doesn't understand.
I'm happy to override the ClassNameLocator and return some hard coded
defaults (as I have few pages and components) but am not sure how...?
Any help is much appreciated.
Steve.

Re: [T5.1] How do you advise ClassNameLocator?
Thanks. The following gives me the same list of interfaces as advising:
@Match(*)
public static T T decorateEverything(ClassT serviceInterface, T
delegate, String serviceId) {
System.out.println(serviceInterface.getName());
return delegate;
}
ClassNameLocator not being one of them.
I have fudged a fix by supplying my own
org.apache.tapestry5.ioc.internal.services.ClassNameLocatorImpl and
ensuring it's further up the classpath than Tapestry's but that's far
from perfect!
The Decorator documentation mentions:
Note: It is not possible to decorate the services of the TapestryIOCModule.
The ClassNameLocator just happens to be an IOC internal class.
The Advice documentation mentions:
Note that some services, especially those built-in to Tapestry IoC, are
marked as not subject to decoration, this applies to service advice as well
as service decoration.
The whole TapestryIOCModule is annotated with
@PreventServiceDecoration so that explains why I can't override it.
Might it be an idea to just annotate individual dangerous services
rather than a blanket ban on overriding all IOC services?

Have you tried decoration instead of method advising? The resulting code

2009/4/24 Blower, Andy andy.blo...@proquest.co.uk: Any time a message, of any category, is added, Blackbird will popup (by design). This surprises me, I also assumed that (since it's a development/debugging tool) the console would be disabled in production mode. I'd be very interested to hear other people's opinion on this. What this means to me, is that after I've carefully constructed all my debug logging calls I have to go and delete them before the code goes live. It's like hunting down System.out's all over again! For lower level logging calls (say debug and info) I don't see why you would want the console popping up in production mode.

[T5.1.0.4] Distinguishing Between Internal and Scripts when Combining
Hi,
If you add a script with an external url then script combining is disabled.
From DocumentLinkerImpl :
public void addScriptLink(String scriptURL) {
...
// If a script with an external URL is added, we can't combine the
scripts after all.
if (combineScripts !scriptURL.startsWith(fullAssetPrefix))
combineScripts = false;
...
}
Would it not be possible to have two buckets of scripts, one for
internal scripts and the other for external? The internal scripts
could then combined into a virtual asset and the external ones
rendered as separate script tags.
The script combining and virtual assets were working wonderfully until
I added script link to Google Analytics on all my pages.
renderSupport.addScriptLink(http://www.google-analytics.com/ga.js;);
I don't want to loose this cool feature of T5 and I would imagine
adding Google Analytics to sites (in the manner above) would be a
rather common thing to do.
Regards,
Steve.

Re: [T5.1.0.2] / [T5.1.0.3] Combining JavaScript Libraries in IE 6
Hi,
We use Jetty 6.1.14 and this happens regardless of whether deployed to
Windows or Linux. We've not noticed this behaviour in Firefox or IE 7,
but it's consistent on IE 6. However, when you refresh the problematic
page then all works fine.
It's almost as if the virtual script is being downloaded after the
Tapestry initialization - hence on page refresh the script is already
cached and all works smoothly. But that does not explain why
everything works when the scripts are not combined. The only obvious
difference to the browser would be the length of the virtual js
filename.
No stack traces are being produced on the server so I was guessing
it's a quirk with IE 6 script loading but wasn't sure if it was down
to our skewed IE 6 or not.
Steve.
P.S. It's a great idea - are there any plans in the pipeline to do
similar with stylesheets?

I've experienced this too, and some others in the list.
The underlying issue is that the combining / gzipping dies in the server
side - the page is loaded but the javascript asset is never delivered to
the browser. However, tapestry includes initialization in the page which
dependes to the asset, which gives error Tapestry does not exist.
Hunt down the stack trace from production and attach it here. Do you also
have tomcat, and develop in windows + deploy to linux?
- Ville
Ps. We're experiencing this randomly, and for us this is not browser
dependent.

[T5.1.0.2] / [T5.1.0.3] BlackBird Info Logging
Hiya, The Tapestry js object has debug, warn and error logging methods to BlackBird but no info logging. Is this due to design because the logging methods are only supposed to be used by Tapestry internal components (and hence not yet required)? Or maybe an wee oversight? Personally, I'm excited at the idea of having BlackBird bundled with T5 and would love to utilise it fully. On a related note, when I send messages to BlackBird via the js Tapestry.debug() method it seems to pop up the BlackBird console window regardless of whether I'm in productionMode or not. Is this the desired behaviour? Or again, am I not supposed to use the Tapestry js logging methods myself?

Re: Problems Deploying T5 Apps with Component Modules in Jetty
Hi Chris, You are correct and I agree with everything you say, no buts. You are even right in your assumption that I'm not aware of the @SubModule annotation. I don't recall seeing it mentioned anywhere, but will look it up in a minute. To address your specific points (...of my inadequacy - ulp!) 1) However which way my Eclipse environment was set up (with disparate projects, maven plugins, etc...) the component module's manifest wasn't being picked up. (I suspect the compiled class folders were on the classpath and not the .jar itself - I never investigated.) As a dirty hack to get both modules loaded, I extended the module class. Wrong, I now know. 2) My thinking was thus; the only reason to enhance / add to an existing app's module would be for creating a test version of your app. I presumed that extending the module class was the only way to do that. I guess that, knowing T5 is still in alpha and not knowing the its code base, when something goes wrong and I've been bashing my head against it for some time, I'm not sure if I've done something really dumb (which has been the case) or if it's a problem yet to be addressed. If it helps redeem me any, I've been an avid follower of Tapestry since v3 and advocate it to all and sundry. And I am truely impressed with the clean design of T5. Regards, Steve.

One of the main bonuses of having component libs is to specifically avoid this rigid coupling. However even if you wanted that, this is what @SubModule is for. Except for maybe adding extra configuration for a test version of an application I can't think why you'd want to extend the module class. 2) Again, extending the module class is (IMO) the Wrong Way(tm) of doing this. I do this kind of testing/demoing for my component lib and have such a test version of an app module. In the test version I simply use @SubModule to 'include' the usual app module.

[T5] Component Module Templates Not Rendering
Hello, The templates in my component module are not being rendered when I deploy my app in a standalone version of Jetty via the webapps dir. All is fine when deployed with the Jetty Launcher in Eclipse. If I add a BeforeRenderTemplate method to the component I can see it being called, so I assume Tapestry knows of the template. I can even add elements to the writer from this method and they are rendered fine. Also, I don't know if this is related or not, but image (possibly all binary?) assets from the component module are served up corrupted. Stylesheet (text) assets are served up fine.

Problems Deploying T5 Apps with Component Modules in Jetty
Hello,
I have a number of T5 web apps that all use a common component module.
In the component's module class (as defined by the
Tapestry-Module-Classes property in its jar's MANIFEST.MF) there is a
simlpe build method:
public static AssetFinder buildAssetFinder(@InjectService AssetSource
assetSource) {
return new AssetFinder(assetSource);
}
All is well whilst developing in Eclipse using the Jetty Launcher but
when I try to deploy in a standalone Jetty instance by copying the war
into its webapps folder I get the following exception:
java.lang.RuntimeException:
Service id 'AssetFinder' has already been defined by
com.alienfactory.websitetags.WebsiteTagsModule.buildAssetFinder(AssetSource)
(at WebsiteTagsModule.java:28)
and may not be redefined by
com.alienfactory.websitetags.WebsiteTagsModule.buildAssetFinder(AssetSource)
(at WebsiteTagsModule.java:28).
You should rename one of the service builder methods.
It's as if the MANIFEST.MF and hence my module class is being parsed
more than once. I've checked the .war and that module class does only
exist the once.
I've also tried autobuilding with the public static void
bind(ServiceBinder binder) method and receive a similar message.
I've done the usual searches (tapestry website, google, mailing lists)
and not found any mention of anyone having deployment problems outside
of Tomcat. Are there any known gotchas with respect to deploying
component modules?
Regards,
Steve.

Re: Problems Deploying T5 Apps with Component Modules in Jetty
Hi,
have you tried explicitly setting the id?
No I didn't try explicitly setting the service id for I only have the
one service which I only define the once. (Will try it tonight
though!)
So, there's no chance that you have a copy of the common module lib on
the general classpath and in WEB-INF/lib?
Nope. It's a brand spanking new install of jetty 5.1.x fresh from the
.zip from the mortbay ftp site. All I've done is copied the .war into
the webapps dir and run start.jar. That's when the exception occurs
and the app never starts up.
I get the same message on fresh installs of Jetty 5.1.9, 5.1.5, 5.1.2
and even Jetty 6.1.6.

Auto binding assigns the class name as the service id, which is logical.
However if you have colliding names then you need to specify unique ids.
The fact that you're seeing this problem in deployment but not
production smells a bit off though. Does there happen to be two copies
of your war lying around? It sounds like that builder method is being
called more than once (very odd), or that another part of the app is
contributing a service with the same name - but if that were the case
you'd probably know it.
