Re: integrating T5 a login form with Spring Security?
You have to provide the login-processing-url to your template file. Look into nu.localhost.tapestry5.springsecuritytest.pages.LoginPage and the respective LoginPage.tml in the webapp of the sample. It's artefact is dependency groupIdnu.localhost.tapestry5.springsecurity/groupId artifactIdtapestry-spring-security-sample/artifactId version1.0.0-SNAPSHOT/version /dependency There will be a final 1.0.0 later this day since Howard announced the final 5.0 for T5. Further you could also use Tapestry Spring Security and exclude the dependency for Spring 2.0 in your pom and include your 2.5 Spring dependencies instead. Visit [1] for an idea about it or read the excellent free book Better builds with Maven [2]. Michael [1] http://maven.apache.org/pom.html#Exclusions [2] http://www.exist.com/better-build-maven Jean Luc schrieb: Hello, I've been trying to integrate T5 and Spring Security (2.0.4, not the older Acegi) but haven't succeeded in making the two work together. The standard way to specify a form login with Spring 2.5 is like below. See the form-login element which specified the login page (Login) and what URL Spring will intercept (the standard j_security_check). b:beans xmlns=http://www.springframework.org/schema/security; http form-login login-page=/Login default-target-url=/Start authentication-failure-url=/Login?login_error=1 login-processing-url=j_security_check / /http I have a typical Login.tml (labels and cosmetic stuff removed for brevity) t:form t:id=loginForm tabletrtdinput type=text t:id=j_username t:type=TextField t:value=j_username//td/tr trtdinput type=text t:id=j_password t:type=PasswordField t:value=j_password//td/tr trinput type=submit value=Log In//td /tr /table /t:form What happens is that the POST that occurs when submitting the form goes to the Login.onSubmit() instead of j_security_check. While it is possible to add code there to call Spring's AuthenticationManager, I would end up duplicating what Spring Security does (the logic to redirect to different pages if the login succeeded or not and so on). I'd like to use Spring since it already implements this. Is it possible to submit the login info to j_security_check instead? Or to forward the request from within Login.onSubmit() to /j_security_check? I went through the Tapestry 5 book by Alexander Kolesnikov, but didn't find this info. Also, I am aware of the tapestry5-acegi extension ( http://www.localhost.nu/java/tapestry5-acegi/) but this one seems under development and for such a simple thing I didn't want to add a dependency on another jar. As you can tell, I'm new to T5. I've had some exposure to T4 and an older version of Spring (2.0) but there things were quite different, both in Tapestry itself and in how Acegi is configured in Spring.

I know how to encode the parameters in the URL and use the onActivate context, but in this case, the data being passed from the external application will exceed the URL length limit so I need to use post. Can anyone advise how to do this? You have to look at the generated HTML fro your page, grab the t:formdata form parameter and (hard)code it into your app which will post to T5, obviously you have to use the appropriate parameter too. Of course you will tie together with that particular version of T5. This way it'll do the job. Yep i know it's no more then an hack but is the only way to do that right now, maybe (i think so) in the future T5 will have more RESTfull features to facilitate this but for now you have to be satisfied.

Re: Layout Border component problem
What happens is that TeacherMode is mutable, and hence leaks state between
different users. You are *not* given a fresh instance on each request.
Instead, instances are pooled and reused.
(Starting with 5.0.17, it is forbidden to have initial values on page
member variables in order to prevent bugs like this.)
One way to handle this situation is:
*...@persist
*private TeacherMode teacherMode;
public void *setupRender()* {
if (teacherMode == null) {
teacherMode = new TeacherMode(); // This will be a private instance per

Hi Jonathan,
thanks for your quick response.
As you asked I uploaded classes I hit the problem in.
Small description: One of my sub-application is Teacher (should be able to
provide a word in foreign language and accept user's answer checks wheather
it is correct)
When user logs in, clicks teacher link is redirected to AvailabaleSets
(which is wrapped by TeacherBorder).
T5.zip file uploaded and it contains:
- Border.java
- Border.tml (pagelinks to all stuff provided by my app)
- TeacherBorder.java
- TeacherBorder.tml (contains all links to navigate my Teacher
sub-application - i.e. TeacherMode - resposnible for 'asking question',
registering results etc)
- AvailableSets.java
- AvailableSets.tml (displays available sets containg words)
- TeacherModePage1.java
- TeacherModePage1.tml (lets user to choose the word's set and decide
about
the questioning mode (mingled or the sequence of words had been added to
the
set) )
- TeacherModePage2.java
- TeacherModePage2.tml (displays questions and lets to type in answers)
TeacherModePage1.java contains the following line:
private TeacherMode teacherMode = new TeacherMode();
I belived that when new page would be displayed (whe user clicks
TeacherMode
in TeacherBorder) a brand new TeacherMode instance would be returned but is
not. And is not because all the classes are already instantiated and T5
gives them back to the user for efficiency.
Please keep in mind this is just the beggining of the work, so not
everything is like it should be from architectural point of view (i.e.
@Persist will be replaced by onPassvate and onActivate). I just wanted to
see how it works.
If any more details are reqiured let me know.

Yes I already tried that.
Also in debugging mode I can see that the AbstractEventMixin.onInternalEvent()
method returns a List with the JSONObjects.
Then the javascript code is called, but the response argument is undefined
I have no clue what causes this problem. I had this working in a previous

Re: Tapestry 5.0 Final Release - 5.0.18
Great news! Knowing this framework is in production use for months now, is there a list of success stories? I think Howard once asked on this list for such stories and the format in which they should be reported. Cheers, Borut
Re: [T5]: query regarding streaming data
Thanks Olle,
However, reading the docs I see that the Streaming applies to
components. In my situation I need to open a new window, which I
currently do with JavaScript (in this example I'm obviously opening a
local file, but as I said, in the real version it needs to come from
the DB):
e.g.:
pa href=javascript:openPdf('file:///c:/DMR2008.pdf')Open a PDF/a/p
which is so I can auto-close the window:
function openPdf(url)
{
windowprops = left=10,top=10,width=1000,height=1100;
if (ChildWin)
{
return false;
}
ChildWin = window.open(url, ChildWin, windowprops);
ResetTimer();
if (TimeOut RefreshRate)
{
setTimeout(CheckClose();,RefreshRate * 1000);
}
}
I really need the streaming to be coming from a URL I am opening and
as far as I can see that won't work as StreamResponse applies to
Components only.
Hmmm. !
p.
Quoting Olle Hallin olle.hal...@gmail.com:
Yes, there is.
Let your handler method return a StreamResponse object.

[T5] onException event
I am using T 5.0.18. In my page class I have an method to catch exceptions:
public Object onException(Throwable cause) {
LOG.info(onException(Throwable cause); cause instanceof +
cause.getClass());
if(cause instanceof OnRequestOnlyException) {
return onRequestOnly;
}
return null;
}
The method is never called.
Is this feature currently broken?

Hello,
I've been trying to integrate T5 and Spring Security (2.0.4, not the older
Acegi) but haven't succeeded in making the two work together.
The standard way to specify a form login with Spring 2.5 is like below. See
the form-login element which specified the login page (Login) and what URL
Spring will intercept (the standard j_security_check).
b:beans xmlns=http://www.springframework.org/schema/security;
http
form-login login-page=/Login
default-target-url=/Start
authentication-failure-url=/Login?login_error=1
login-processing-url=j_security_check /
/http
I have a typical Login.tml (labels and cosmetic stuff removed for brevity)
t:form t:id=loginForm
tabletrtdinput type=text t:id=j_username t:type=TextField
t:value=j_username//td/tr
trtdinput type=text t:id=j_password t:type=PasswordField
t:value=j_password//td/tr
trinput type=submit value=Log In//td /tr
/table
/t:form
What happens is that the POST that occurs when submitting the form goes to
the Login.onSubmit() instead of j_security_check. While it is possible to
add code there to call Spring's AuthenticationManager, I would end up
duplicating what Spring Security does (the logic to redirect to different
pages if the login succeeded or not and so on). I'd like to use Spring since
it already implements this.
Is it possible to submit the login info to j_security_check instead? Or to
forward the request from within Login.onSubmit() to /j_security_check?
I went through the Tapestry 5 book by Alexander Kolesnikov, but didn't
find this info. Also, I am aware of the tapestry5-acegi extension (
http://www.localhost.nu/java/tapestry5-acegi/) but this one seems under
development and for such a simple thing I didn't want to add a dependency on
another jar.
As you can tell, I'm new to T5. I've had some exposure to T4 and an older
version of Spring (2.0) but there things were quite different, both in
Tapestry itself and in how Acegi is configured in Spring.
Advice is appreciated,

Re: Tapestry 5.0 Final Release - 5.0.18
Congratulations Howard and all contributors for making our lives as web developpers, architects, project managers, ... easier ! Best Regards Stephane Howard Lewis Ship a écrit : Apache Tapestry 5.0 final release (5.0.18) After nearly three years of development, the final release of Apache Tapestry 5.0 is now available for download. Apache Tapestry 5 is a total rewrite of the Tapestry web application framework, bringing forward Tapestry's core concepts: reusable components, true encapsulation, readable templates, well thought-out localization/internationalization, and easy management of server-side state. Tapestry 5 builds on top of this with a host of new features: * True POJO component classes: no base classes to extend, no interfaces to implement. * Live class reloading: no need to redeploy to see code changes. * XML templates with namespaces. * Minimal configuration via naming conventions and annotations. * Integrated Ajax support, built on top of Prototype and Scriptaculous. * Automatic client-side form input validation. * High performance via pooled objects (and by avoiding the use of reflection). * Automatic REST-style URLs. * Built-in integration with Hibernate and Spring. * Best-of-breed exception reporting. * Built-in extensible mega-components: BeanEditForm, BeanDisplay and Grid (to edit and display any JavaBean or collection of JavaBeans). Tapestry organizes your application into pages, and components within pages; pages and components are ordinary POJOs: not singletons (like servlets). Tapestry combines pages, page templates, components, component templates, and other resources together for you, managing server-side state, the creation of URLs and the dispatch of incoming requests. You build your application in terms of the methods and properties of your objects, not in terms of URLs or the Servlet API. Tapestry features great exception reporting to keep you on track, and live class reloading to keep you agile. Tapestry templates are XML documents, using a namespace for Tapestry-specific elements. Tapestry is designed to be easy to develop, using any standard IDE with an XML editor. Tapestry is simple, sensible and fun. It keeps you productive by freeing you from the boring, mechanical aspects of web application development. You can stay focused on what makes your application interesting and unique, and let Tapestry handle all the ugly plumbing. Tapestry is made available under the Apache Software License 2.0. Tapestry is free to download, free to use, free to redistribute and free to modify. Tapestry 5.0.18 * Project page: http://tapestry.apache.org/tapestry5/ * Download: http://tapestry.apache.org/download.html * Release Notes: http://tapestry.apache.org/tapestry5/release-notes.html * Upgrade Notes: http://tapestry.apache.org/tapestry5/upgrade.html * Via Maven: dependency groupIdorg.apache.tapestry/groupId artifactIdtapestry-core/artifactId version5.0.18/version /dependency
T5: How to initialize page members
Hi,
Beginning with 5.0.17 is is forbidden to have initial values on page
members, in order to prohibit state leakage between sessions.
This is fine, since it prevents bugs that can be very tricky to isolate.
On the other hand, it leads to clumsy code.
Instead of
*private Foo foo = new Foo();
*
you have to write
*...@persist private Foo foo;
void setupRender() {
if (foo == null) {
foo = new Foo();
}
}
*
This contradicts to the Tapestry principle *the simplest choice should be
the correct choice.*
IMHO it should be ok to initialize the member in the declaration if it can
be guaranteed that the value is immutable.
Therefore, I propose that classes that are known to be immutable
(java.lang.Integer etal) and classes that are annotated @Immutable should
be allowed as initializers.
See http://www.jcip.net/annotations/doc/net/jcip/annotations/Immutable.html.
The package is available at the Maven repo (group:net.jcip
artifact:jcip-annotations version:1.0), and it's license (
http://creativecommons.org/licenses/by/2.5) is AFAIK compatible with
Tapestry's.

Tapestry 5 page persistence design issues
Hello, I must say first that I really like the design concept of the Tapestry 5. It's component oriented design and IoC supporting it are really promising. But could somebody please explain me the logic behind Tapestry 5 page persistence handling. I just do not get it. I think that I have a pretty common use case where there is a page with a list of items with links to the item detail page. Users usually open many different detail pages for further investigation (in a new tab or in a new window). A real world example of this is eBay, where you can open several action items to view detailed information. Let's imagine that the detail page has to hold it's state somehow. Now the situation gets really weird. As far as I understand (please tell me that I'm wrong), Tapestry 5 keeps only one copy of the persistent state per page and session, no mater how many instances of the same page are actually created by the user on the client side. Good example of this misbehavior is Tapestry 5 grid component. Put it on the page, create two instances of the page and use the column sorting feature and look what happens. You might say that you can use the client side persistence strategy, but there is another and bigger problem. The persistence strategy must be set on the field level and not on the page level. Honestly, please tell me one use case where this is needed? This design fault disables the possibility to change grid component persistence strategy to match the page strategy. I would like to suggest also some possible solutions for the further discussion. First, a default persistence strategy should be set on the page level (with the annotation). When not set, it will default to the session strategy (or to omething that is appropriate). Now, when there is really a need for a different strategy for one field, then and only then this should be set on the field level. The second thing would be a new persistence strategy, that will keep one state per one page instance. It is quite tricky to archive because an unique id should be generated and tracked per page instance. The hardest part is to make sure that every component will include this id with it's conversation with the server side.

Re: [T5]: query regarding streaming data
It works fine.
Try something like this:

return new PDFStreamResponse(dao.getPDF(id));
}
public Link getPDFLink() {
return resources.createActionLink(pdf, false);
}
}

byte[] pdf;
public PDFStreamResponse(byte[] pdf) {
this.pdf = pdf;
}
public String getContentType() {
return application/pdf;
}
public InputStream getStream() throws IOException {
return new ByteArrayInputStream(pdf);
}
public void prepareResponse(Response response) {
}
}

Thanks Olle,
However, reading the docs I see that the Streaming applies to
components. In my situation I need to open a new window, which I
currently do with JavaScript (in this example I'm obviously opening
a local file, but as I said, in the real version it needs to come
from the DB):
e.g.:
pa href=javascript:openPdf('file:///c:/DMR2008.pdf')Open a
PDF/a/p
which is so I can auto-close the window:
function openPdf(url)
{
windowprops = left=10,top=10,width=1000,height=1100;
if (ChildWin)
{
return false;
}
ChildWin = window.open(url, ChildWin, windowprops);
ResetTimer();
if (TimeOut RefreshRate)
{
setTimeout(CheckClose();,RefreshRate * 1000);
}
}
I really need the streaming to be coming from a URL I am opening and
as far as I can see that won't work as StreamResponse applies to
Components only.
Hmmm. !

Re: [T5]: query regarding streaming data
Do you mean a data stream?
Since you mentioned a PDF I assume this to be the case... simply return a
StreamResponse... you can use a page or eventlink, see:
http://tapestry.apache.org/tapestry5/apidocs/org/apache/tapestry/StreamResponse.html
For example:
return new StreamResponse() {
public String getContentType() {
return application/pdf;
}
public InputStream getStream() {
return stream;
}
public void prepareResponse(Response response) {
response.setHeader(Content-Disposition,
attachment; filename= +
fileName);
response.setContentLength(docLength);
}
};

RE: [ANN] t5components 0.5.18 is now available for Tapestry 5.0.18
Hi,
I use the @OnEvent mixin to create dependent selects:
I use it like below. But the problem is that the onCompleteOperatorChange

response object is undefined
Any ideas how this is possible. The javascript function is called, but the
response is undefined
@OnEvent(component = operator, value = change)
public JSONArray onChangeOperatorEvent(String value) {
JSONArray jsonArray = new JSONArray();
for (Plaza plaza : getDestinationSelectValues(value)) {

jsonObject.put(value, plaza.getId());
jsonObject.put(label, plaza.getDescription());
jsonArray.put(jsonObject);

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++) {

You're correct about static final. Didn't think of that .
But still I think there is room for improvement:
Consider this use case that is quite clumsy to implement as it is today:
public class APageThatContainsAGrid {
@Persist private int rowsPerPage = 10; // forbidden!
void onAction(int rows) {
this.rowsPerPage = rows;
}
}
and in the template a t:grid rowsPerPage=rowsPerPage .../ and a couple of

You're right.
This contradicts to the Tapestry principle *the simplest choice should be

I don't think so. You have to remember that Tapestry polls page instances, so,
after one request, Tapestry must restart the page fields values. And that the
value of a non-primitive field is a reference to an object, not an object
itself.
IMHO it should be ok to initialize the member in the declaration if it can be
guaranteed that the value is immutable.
IMHO, the best way to declare a field that is immutable is to make it final and
static (i.e. constant) for it, not a private field. ;)

Re: Layout Border component problem
Ok found an answer to my second question,
some info is provided here:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/rendering.html
but still would be happy if you could answer to my first question.
cheers

Olle,
thanks a lot. I knew what was wrong but had no idea how to deal with that.
I am gonna check it out at home 'cause now I am at work.
But I have some questions to the resolve you suggetsed:
- Starting with 5.0.17, it is forbidden to have initial values on page
- what does it mean it is forbidden? I did not notice any repoerts during
runtime and no during compilantion neither.
- what is setupRender() method? it will be called automatically ?
thanks again

Hi Jonathan,
thanks for your quick response.
As you asked I uploaded classes I hit the problem in.
Small description: One of my sub-application is Teacher (should be able
to
provide a word in foreign language and accept user's answer checks
wheather
it is correct)
When user logs in, clicks teacher link is redirected to AvailabaleSets
(which is wrapped by TeacherBorder).
T5.zip file uploaded and it contains:
- Border.java
- Border.tml (pagelinks to all stuff provided by my app)
- TeacherBorder.java
- TeacherBorder.tml (contains all links to navigate my Teacher
sub-application - i.e. TeacherMode - resposnible for 'asking question',
registering results etc)
- AvailableSets.java
- AvailableSets.tml (displays available sets containg words)
- TeacherModePage1.java
- TeacherModePage1.tml (lets user to choose the word's set and decide
about
the questioning mode (mingled or the sequence of words had been added to
the
set) )
- TeacherModePage2.java
- TeacherModePage2.tml (displays questions and lets to type in answers)
TeacherModePage1.java contains the following line:
private TeacherMode teacherMode = new TeacherMode();
I belived that when new page would be displayed (whe user clicks
TeacherMode
in TeacherBorder) a brand new TeacherMode instance would be returned but
is
not. And is not because all the classes are already instantiated and T5
gives them back to the user for efficiency.
Please keep in mind this is just the beggining of the work, so not
everything is like it should be from architectural point of view (i.e.
@Persist will be replaced by onPassvate and onActivate). I just wanted
to
see how it works.
If any more details are reqiured let me know.

Re: Tapestry 5 page persistence design issues
Hi! This discussion was already made in this mailing list. There's a very nice archive at http://www.nabble.com/Tapestry---User-f340.html. Search for conversation scope (http://www.nabble.com/forum/Search.jtp?query=conversation+scopesort=datelocal=yforum=340) or Seam integration. Em Mon, 15 Dec 2008 09:28:45 -0300, kristjankelt kristjank...@hotmail.com escreveu: Hello, I must say first that I really like the design concept of the Tapestry 5. It's component oriented design and IoC supporting it are really promising. But could somebody please explain me the logic behind Tapestry 5 page persistence handling. I just do not get it. I think that I have a pretty common use case where there is a page with a list of items with links to the item detail page. Users usually open many different detail pages for further investigation (in a new tab or in a new window). A real world example of this is eBay, where you can open several action items to view detailed information. Let's imagine that the detail page has to hold it's state somehow. Now the situation gets really weird. As far as I understand (please tell me that I'm wrong), Tapestry 5 keeps only one copy of the persistent state per page and session, no mater how many instances of the same page are actually created by the user on the client side. Good example of this misbehavior is Tapestry 5 grid component. Put it on the page, create two instances of the page and use the column sorting feature and look what happens. You might say that you can use the client side persistence strategy, but there is another and bigger problem. The persistence strategy must be set on the field level and not on the page level. Honestly, please tell me one use case where this is needed? This design fault disables the possibility to change grid component persistence strategy to match the page strategy. I would like to suggest also some possible solutions for the further discussion. First, a default persistence strategy should be set on the page level (with the annotation). When not set, it will default to the session strategy (or to omething that is appropriate). Now, when there is really a need for a different strategy for one field, then and only then this should be set on the field level. The second thing would be a new persistence strategy, that will keep one state per one page instance. It is quite tricky to archive because an unique id should be generated and tracked per page instance. The hardest part is to make sure that every component will include this id with it's conversation with the server side.

Re: T5: How to initialize page members
You're correct about static final. Didn't think of that [?].
But still I think there is room for improvement:
Consider this use case that is quite clumsy to implement as it is today:
public class APageThatContainsAGrid {
@Persist private int rowsPerPage = 10; // forbidden!
void onAction(int rows) {
this.rowsPerPage = rows;
}
}
and in the template a t:grid rowsPerPage=rowsPerPage .../ and a couple
of action links for modifying rowsPerPage.
Why is it prohibited to initialize rowsPerPage in the declaration? An int is
definitely immutable. It's not even an object...

Re: [T5] Handle post from external application
I was talking about posting from another web application to a Tapestry page, but it really shouldn't matter where the post is coming from (i.e. Java application, Perl script, etc). My goal is to have a page that operates normally for Tapestry requests or REST URL requests from onActivate contexts, but also have the same page be able to respond to posts from other applications. Thiago, can the approach you propose coexist with an onActivate context for Tapestry requests or are they mutually exclusive? In what page method does getting the request parameters happen (e.g. onActivate?) ? Thanks!

In addition to onActivate and setupRender, you should also look at

I tend to just set id's in onActivate and leave heavier loading for
onPrepare/setupRender. Having said that, I think that the
tapestry-hibernate integration does primary key encoding to allow the use

[T5 5.0.18] - How to 'turn on' dynamic validation
Hi Guys, I have a following piece of code in my *.tml file: t:form input type=text t:type=textfield t:value=toCreate.name t:validate=required/ input type=submit t:type=submit t:id=cancelButton value=Cancel/ input type=submit t:type=submit t:id=nextButton value=Next/ /t:form As you can see I added two submit buttons and a validation to a textfield. The problem is that I would like to 'turn on' this validation only when user clicks Next button. Currently when the textfield is empty and Cancel button is clicked the T5 says that field cannot be empty. Probably this is possible on server side only but maybe I am wrong. Thanks in advance kawes -- View this message in context: http://www.nabble.com/-T5-5.0.18How-to-%27turn-on%27-dynamic-validation-tp21020626p21020626.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: T5: How to initialize page members

Why is it prohibited to initialize rowsPerPage in the declaration? An int
is definitely immutable. It's not even an object...
True, but then the question arises will it become more confusing and appear
inconsisant? Especially for new users still learning Tapestry, they may get
confused as to why primitives can be initialized but not Objects?

Subject: Re: T5: How to initialize page members
You're correct about static final. Didn't think of that .
But still I think there is room for improvement:
Consider this use case that is quite clumsy to implement as it is today:
public class APageThatContainsAGrid {
@Persist private int rowsPerPage = 10; // forbidden!
void onAction(int rows) {
this.rowsPerPage = rows;
}
}
and in the template a t:grid rowsPerPage=rowsPerPage .../ and a couple
of action links for modifying rowsPerPage.
Why is it prohibited to initialize rowsPerPage in the declaration? An int
is definitely immutable. It's not even an object...

Hi,
Hi!
Beginning with 5.0.17 is is forbidden to have initial values on page
members, in order to prohibit state leakage between sessions.
This is fine, since it prevents bugs that can be very tricky to isolate.
You're right.
This contradicts to the Tapestry principle *the simplest choice should be
the correct choice.*
I don't think so. You have to remember that Tapestry polls page instances,
so, after one request, Tapestry must restart the page fields values. And
that the value of a non-primitive field is a reference to an object, not an
object itself.
IMHO it should be ok to initialize the member in the declaration if it can
be guaranteed that the value is immutable.
IMHO, the best way to declare a field that is immutable is to make it final
and static (i.e. constant) for it, not a private field. ;)

Re: Which annotation to be used in page class?

Instead of use

It works well.
Does the @Id annotation can't be used in a page class?

Hi All,
I have a fairly straight forward bean edit form on a page. Its a
create new user form so, I want to check the user doesn't already
exist and that the two password fields match. I do this validation in
the onSubmit method but I am struggling to use the error reporting
mechanism to inform the user.
How do I get access to the form component to generate the proper error
messages?

PageLinkTarget, where did it go?
I am in the process of updating our application from Tapestry version 5.0.15 to 5.0.18 and it looks like PageLinkTarget has disappeared. We have been following the Unit testing as outlined http://tapestry.apache.org/tapestry5/guide/unit-testing-pages.html which uses the PageLinkTarget when testing a page with a context. I looked around and can't find the class or any documentation on what its replacement is. Any help is greatly appreciated.

The injection of the form and the field and the error message recording
are correct, but your suggestion of using the onSuccess() method isn't
correct
Validation should be done at onValidateForm() (VALIDATE_FORM event), not
at the onSuccess (SUCCESS event). The SUCCESS event is meant to be fired
only if validation was ok.

No, you can't. But you can add more modules (each one with its pages,
components, mixins and base packages).
To build a module, follow this steps. The examples are taken from the
Tapestry CRUD package (http://www.arsmachina.com.br/project/tapestrycrud)
1) Create a class and add this method to it. I'll call it
TapestryCrudModule:
public static void
contributeComponentClassResolver(ConfigurationLibraryMapping
configuration) {
String prefix = crud;
String rootPackage = br.com.arsmachina.tapestrycrud;
configuration.add(new LibraryMapping(prefix, rootPackage));
}
2) Add it to your application through Tapestry IoC. There are two options,
and you can use both if you want:
1. In your AppModule, add the @SubModule annotation:
@SubModule({TapestryCrudModule.class, AnyOtherModuleClass.class})
public class AppModule {
...
}
2. Package your classes inside a JAR file and add this line to the
MANIFEST.MF file:
Tapestry-Module-Classes:
br.com.arsmachina.tapestrycrud.ioc.TapestryCrudModule
This option has a very good advantage: you don't have to configure your
module: it is loaded automatically by Tapestry-IoC. Just include the
package JAR in the classpath and that's all. :)

Re: T5: a default notification page
It is a major pain with Tomcat IMHO. As Andreas points out if you stop Tomcat nothing will run, if you run Apache in front then Apache uses the directive 'ErrorDocument' that allows you to override a '503 Service Unavailable' error displaying your custom page. If you don't run Apache in front and simply stop the application, Tomcat will show its standard 503 page which can *NOT be overridden without fiddling with Tomcats internals, as Tomcat uses embedded code to generate 503 pages on the fly, why it does it for 503 pages and not the other is a mystery. The one thing you could do though if your configuration allows, is override the 404 page in Tomcats root (not your application) and use undeploy instead of stop before doing your changes. cheers, Peter - Original Message - From: Andreas Andreou andre...@gmail.com To: Tapestry users users@tapestry.apache.org Sent: Tuesday, 16 December, 2008 2:16:21 AM GMT +02:00 Athens, Beirut, Bucharest, Istanbul Subject: Re: T5: a default notification page if you shutdown tomcat, tapestry app wont be running ;) If you have apache setup in front of tomcat, you can add redirect rules to a static html page see http://significantbits.wordpress.com/2007/03/15/setting-a-maintenance-page-in-apache-2/ or similar posts On Tue, Dec 16, 2008 at 1:50 AM, Thiago H. de Paula Figueiredo thiag...@gmail.com wrote: Em Mon, 15 Dec 2008 19:41:19 -0300, Angelo Chen angelochen...@yahoo.com.hk escreveu: Hi, Often I need to shutdown tomcat in order to do some maintenance work, is there a way to define a page in a T5 application so that all links to the application goes to that page? thanks.

IMO it is recommended to do a cold start of Tomcat after *each* redeploy of webapps. Else you will sooner or later run into mysterious problems, caused by memory leaks and such. This will also verify that Tomcat is able to start after a power outage. (In development mode, this is of course not necessary.) So I'd advice you to put an Apache in front, and let it redirect to the static service page when you take Tomcat down. This will also give you freedom to do maintenance on Tomcat itself. Olle 2008/12/16 Peter Stavrinides p.stavrini...@albourne.com It is a major pain with Tomcat IMHO. As Andreas points out if you stop Tomcat nothing will run, if you run Apache in front then Apache uses the directive 'ErrorDocument' that allows you to override a '503 Service Unavailable' error displaying your custom page. If you don't run Apache in front and simply stop the application, Tomcat will show its standard 503 page which can *NOT be overridden without fiddling with Tomcats internals, as Tomcat uses embedded code to generate 503 pages on the fly, why it does it for 503 pages and not the other is a mystery. The one thing you could do though if your configuration allows, is override the 404 page in Tomcats root (not your application) and use undeploy instead of stop before doing your changes. cheers, Peter - Original Message - From: Andreas Andreou andre...@gmail.com To: Tapestry users users@tapestry.apache.org Sent: Tuesday, 16 December, 2008 2:16:21 AM GMT +02:00 Athens, Beirut, Bucharest, Istanbul Subject: Re: T5: a default notification page if you shutdown tomcat, tapestry app wont be running ;) If you have apache setup in front of tomcat, you can add redirect rules to a static html page see http://significantbits.wordpress.com/2007/03/15/setting-a-maintenance-page-in-apache-2/ or similar posts On Tue, Dec 16, 2008 at 1:50 AM, Thiago H. de Paula Figueiredo thiag...@gmail.com wrote: Em Mon, 15 Dec 2008 19:41:19 -0300, Angelo Chen angelochen...@yahoo.com.hk escreveu: Hi, Often I need to shutdown tomcat in order to do some maintenance work, is there a way to define a page in a T5 application so that all links to the application goes to that page? thanks. I haven't tested, but maybe you can decorate ComponentClassResolver.resolvePageNameToClassName() and ComponentClassResolver.resolvePageClassNameToPageName() to always return your application-out-of-order page. The AOP possibilities in Tapestry 5 are almost endless . . .
