Re: how to let actionlink to open another page like target=_blank?
Enjoy :)
As you can see, this is accomplished with only a few lines of actual code.
Of course, it is easy to extend with parameters to open up event type,
window attributes and so on... So far, I don't need anything like that.
PopupPageLink.java:
@IncludeJavaScriptLibrary(PopupPageLink.js)
public class PopupPageLink {
@Inject
private ComponentResources resources;
@Environmental
private RenderSupport renderSupport;
@InjectContainer
private ClientElement container;
@Parameter(required = true, defaultPrefix = BindingConstants.LITERAL)
private String page;
@Parameter
private Object[] context;
void afterRender() {
Link link = resources.createPageLink(page, true, context);
renderSupport.addScript(new PopupPageLink('%s', '%s');,
container.getClientId(), link);
}
}
PopupPageLink.js:
var PopupPageLink = Class.create();
PopupPageLink.prototype = {
initialize: function(id, link) {
this.element = $(id);
this.link = link;
Event.observe(this.element, 'click',
this.onclick.bindAsEventListener(this));
},
onclick: function() {
var width = 800;
var height = 600;
varname = 'dialogWindow';
var win = window.open(this.link,name,'width=' + width + ',height=' +
height +
',resizable=yes,scrollbars=yes,menubar=no,screenX=0,screenY=0,left=0,top=0'
);
win.focus();
}
}

Re: Tapestry 5.1: Wait for Page
Beyond that, the behavior can be changed by monkey-patching the JavaScript and the CSS. The trouble with that is when you change Tapestry's JavaScript you also need to be mindful of these patches and maintain them between releases. Why not use a property on the link to switch it off?, IMHO it just makes more sense that the use of effects and such remains optional. So you could have something like: t:actionlink disableEffect=list,of,effects,to,remove / Regards, Peter - Original Message - From: Howard Lewis Ship hls...@gmail.com To: Tapestry users users@tapestry.apache.org Sent: Friday, 6 March, 2009 20:37:56 GMT +02:00 Athens, Beirut, Bucharest, Istanbul Subject: Re: Tapestry 5.1: Wait for Page It only affects Ajax links; they must explicitly add an onclick event handler attributes.

Tapestry-Hibernate Rollback
Hello, i've using tapestry-hibernate with the latest snapshot but i am
having issues with transaction rollbacks.
I am using Derby and Hibernate configured with autocommit=false, but
if i throw a RuntimeException the transaction is never rolled back. In
the stack trace i can see that the HibernateTransactionAdvisorImpl is
throwing back exception, what means that the transaction is being
aborted, but in my database i still can see the data.
This is the stack trace i get:

Re: Tapestry-Hibernate Rollback
Ok, the transaction is being rollback, but then there is something i
don't get about @CommitAfter.
What happens if a @CommitAfter method calls a different @CommitAfter
method? Are the transactions nested? would the whole transaction will
only be committed after the first method returns? or would there be a
different transaction for each of the methods?
Thanks

Re: problem tapestry-spring-security plugin: UserDetailsService implementation not found
As the name says, the sample application does declare the
UserDetailsService. Look at
nu.localhost.tapestry5.springsecuritytest.services.TestsecurityModule
there you'll find the build method
public static UserDetailsService buildUserDetailsService( @Inject
PasswordEncoder encoder, @Inject
SaltSource salt ) {
return new MyUserDetailsService( encoder, salt );
}
This module is in fact using the SpringSecurityModule like you'll
probably do.

It does not find the UserDetailsService implementation though I

It looks it up via Tapestry-IoC. Actually, this error messages is
given by T-IoC, not Tapestry-Spring Security yourself. Just make sure
you declare your UserDetailsService implementation as a service in
your AppModule class (or any other Tapestry-IoC module).
Yes, you're right adding this interface-implementation mapping to
AppModule made it work.
But I wonder why it works in the sample application from the
tapestry-spring-security module, which has no AppModule defined. I
guess then some tapestry magic comes in place (maybe scanning for
implementors of interfaces...).

Re: [T5 5.0.18] java.lang.IllegalStateException: Cannot create a session after the response has been committed
I have a filer to trim off the long jsession IDs from url
You can do so, but IMHO that should never be necessary, the session id is
encoded into the URL only once, and then removed by the container (that is if
you have cookies enabled in the browser). It provides a backwards compatibility
mechanism and support for devices that can't support cookies. The only other
reason that it might be encoded request after request is if you are creating a
new session with each request (a configuration problem that can happen for
instance when you have a problem with your front end - Apache mod_rewrite),
which is not mapping your cookie correctly to your back end (Tomcat / Jetty
etc).
Returning true is interpreted as a terminator for the request by your
container, false allows the request to continue naturally, so if you call
something like session.invalidate(), immediatly after call return true; to
terminate, invalidate acts like a finalize on the request, so anything that
trys to do something with it will cause an IllegalStateException.
The problem I was having the other day related to lazy loading, after an
invalidate, I could not initialize a new page because a new session could not
be instantiated at that point, simply setting the property before the
invalidate fixed that, the second issue was the use of the Response Tapestry
service rather than HttpServletResponse, where the later cannot be tracked by
Tapestry so there is a timing issue (like a race condition), hence using the
first was the solution.
Cheers,
Peter

Re: generics and pages, components and edit blocks
Although you can't use generics directly, I presume you can define a
subclass that inherits from a given generic superclass.
For instance,
class CrudPageT {
// Stuff with T
}
class CustomerCrud extends CrudPageCustomer {
}
Would this work? I suppose if you used a generic service, then you would
have to also instanciate it before using it:
class CrudServiceT { /* stuff */ }
abstract class CrudPageT {
protected abstract CrudServiceT getCrudService();
}
class CustomerCrudService extends CrudServiceCustomer { }
class CustomerCrudPage extends CrudPageCustomer {
@Inject
private CustomerCrudService service;
protected CustomerCrudService getCrudService() { return service; }
}

Given that the language keeps changing/moving forward, this seems like an

eventually want to consider techniques that wish to leverage Generics.
Obviously, registering something like DataServiceMovie.class is illegal

Obviously from a page/component standpoing, there'd have to be a new

And Services (interfaces and implementations) would be a completely

[T5.1.0.0] Loop in Form problem introduced in T5.1.0.0
Hi, I have a loop in a form displaying non form information. An ajax call can update the source of the Loop. When the loop has less, or different items in it during submit then when the form was initiated, the following exception is thrown. Loop.RestoreStateFromStoredClientValue() seems to be causing this problem. My question; Why does the form care about restoring state of a Loop not containing any FormItems?

T5: passing a form in the URL?
Hi,
I have a page which has a form like this:
t:form t:id=search
input t:type=select t:id=category model=categorySelectModel
t:value=category /
input t:type=textfield t:id=name t:value=name /
input t:type=submit name=Submit t:id=Submit /
/t:form
in the onSuccess event I'm doing:
@InjectPage
private ShowResults showResults;
Object onSuccessFromSearch() {
showResults.setlst(lst);
return searchResults;
}
Instead of InjectPage, is there a way to push the form to ShowResults in the
URL, something like what Google is doing:
http://www.google.com/search?hl=enq=TapestrybtnG=Google+Searchmeta=

cross field validation with empty fields
Sorry to ask for this again, but I have seen no answer. I will get no answer again I will stop asking for this, of course. TIA Hello, we are using T4.1 We have to validate a form and we don't want to do it client side. Let say we have three text fields. The validation should implement the following rule: if (fielda=) (fieldb= || fieldc=) then throw new Exception(); The problem is that we cannot link the validation to neither field because they can be empty and the custom validator we are trying to implement is nevere called if the field is empty. We tried to follow the Identity validator but it is also not called when the field to which is associated is empty. Is there another way to accomplish cross field validation ? It seems to us that in T4.1 lacks a validator attribute for the form component. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Tapestry JSONObject : no 'function' type, any workaround ?
toString method of JsonObject would double quote our value.
One way is to create some data type extends jsonobject to encapsule your data
and override the toString method. I haven't tried it yet.
public String toString() {
return Element.show;
}

Re: T5: passing a form in the URL?
Whether or not you can do this, I would be very very careful about
where you do this. Passing form data on the url is one of the easier
entry-points to a cross-site request forgery (CSRF) attack. While for
something like a search (or any read-only operation) this isn't an
issue, but if you are changing state, especially users' state, such as
their contact e-mail address or password, this is how request pages
get hijacked. Just a point to keep in mind. CSRF isn't impossible
with a form post, but it's slightly harder to execute.

Shoud I really use (and only this) instead?
classpath:net/sourceforge/tapestryjfly/dojotapestry5/dojo-1.2.3/dojo/dojo.js
I guess it should be classpath:/net (note the slash), so you
don't have problems with relative paths.

Nile,
do re-read the T5 docs (e.g.
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/ActionLink.html
,
), I think what you're trying to accomplish with your remotelink
mixin is
already being accomplished w/ zones:
t:actionLink t:id=foo t:zone=barZoneAjaxy goodness/t:actionlink
t:zone t:id=barZone
!-- the stuff here will be updated with the content of the block --
/t:zone
t:block t:id=updateBlock
!-- this is the stuff that you want to show up when you click on the
link in the barZone --
/t:block
then, in your code:
@Component
private Block updateBlock
public onActionFromFoo() {
return updateBlock;
}
Cheers,
Alex Kotchnev

you can simple use

My first question is : what should ajax action return? json? html

One of t5's benefit is you can use dreamweaver edit the tml”.
In example code, pagelink work fine. because it return html. but
actionlink is not perfect.
My seconde question is : how to return html fragment in action.

RE: cross field validation with empty fields
Ivano,
I'm pretty sure what you want to do is provide an onValidate method in
your page class. That method gets called expressly for doing more
complicated validation. If you have more than one form, you'll have to
further specify it e.g. onValidateFromMyFormName (or use @OnEvent
annotation). Here's some abbreviated code:
@InjectComponent(fielda)
private TextField fieldaComponent;
@InjectComponent
private Form formComponent;
...
Object onValidate() {
If (fielda == null)
formComponent.recordError(fieldaComponent, Example error
message for fielda);
if (fielda==) (fieldb== || fieldc==)
throw new RuntimeException();
return null; // this will keep you on the same page
//return NewPage.class; // this will goto the NewPage page, etc.
etc.
}
You may just want to provide a validation message. I've shown an
example using fielda in the preceding code.
Read the docs on the Form component, and see the examples in the user
guide.
Cheers

Subject: cross field validation with empty fields
Sorry to ask for this again, but I have seen no answer.
I will get no answer again I will stop asking for this, of course.
TIA
Hello, we are using T4.1
We have to validate a form and we don't want to do it client side.
Let say we have three text fields.
The validation should implement the following rule:
if (fielda=) (fieldb= || fieldc=)
then throw new Exception();
The problem is that we cannot link the validation to neither field
because they can be empty and the custom validator we are trying to
implement is nevere called if the field is empty.
We tried to follow the Identity validator but it is also not called
when the field to which is associated is empty.
Is there another way to accomplish cross field validation ?
It seems to us that in T4.1 lacks a validator attribute for the form
component.

Inherit prefix in templates
Hi all,
Prior to 5.1 in places I used the prefix inherit: in my templates which
seemed to work quite well. Although it is not listed as a standard binding
prefix, it is used as a special case... a mention of it is made here:
http://tapestry.formos.com/nightly/tapestry5/guide/parameters.html
In 5.1 it seems that it no longer working as I expected, I get the feeling I
should no longer be duplicating the property in parent and child, but I have
looked through the release notes but could not find any clue as to what may
have changed.
I also noticed this:
http://tapestry.apache.org/tapestry5.1/apidocs/org/apache/tapestry5/annotations/Component.html#publishParameters(),
so I am wandering what the correct approach is now.
Here is an example for clarity. In my containing component is the following
method, which is also duplicated in the child component:
@Parameter(name = contextVariables)
private List? contextVariables_;
And then I have for example in my tml:
t:header contextVariables=inherit:contextVariables/
So I could propagate these parameters... I also use a custom annotation to bind
these parameters whenever I need them, for example I have a bread-crumb
component that uses them as follows:
@Target(TYPE)
@Retention(RUNTIME)
@Documented
public @interface ContextVariables { ... }
Any help on fixing this would be greatly appreciated!
Thanks,
Peter

Re: Inherit prefix in templates
Looks like this is related to:
https://issues.apache.org/jira/browse/TAP5-487
See the bottom of this page:
http://tapestry.formos.com/nightly/tapestry5/guide/parameters.html
for more details.
However, if, in fact, inherit is no longer functional, that would
still represent a regression, and you should submit a bug report,
attaching, at a minimum, a sample project that illustrates the problem.

But the Tapestry complains with java.lang.IllegalArgumentException Input string 'amFuZXpuOu47TZYaxgNZ297XcGQFHLQ=' is not valid; the character '=' at position 32 is not valid. which I can understand as it decodes the link automatically Stack trace * org.apache.tapestry5.internal.services.URLEncoderImpl.decode(URLEncoderImpl.java:143) * org.apache.tapestry5.internal.services.ContextPathEncoderImpl.decodePath(ContextPathEncoderImpl.java:70) * org.apache.tapestry5.internal.services.PageRenderDispatcher.process(PageRenderDispatcher.java:88) What is the cleanest solution?

Re: cross field validation with empty fields
I'm not familiar worth T4.1 but it seems to me that you could put something
in the submit or success handler that validates.
Take a look here -
http://tapestry.apache.org/tapestry5/guide/validation.html and find the
following snippet:
public class Login
{
*String onSuccess()
{
if (!authenticator.isValid(userName, password))
{
form.recordError(passwordField, Invalid user name or
password.);
return null;
}*
return PostLogin;
}
Oddly enough, it is NOT the validation handler I want to bring to your
attention to (here on this validation.html page :) and again, obviously,
this is Tapestry 5 - but notice how authentication is done in the SUCCESS
handler. I would try to do something similar (albeit validation) to look at
the fields you are processing.

Ivano,
I'm pretty sure what you want to do is provide an onValidate method in
your page class. That method gets called expressly for doing more
complicated validation. If you have more than one form, you'll have to
further specify it e.g. onValidateFromMyFormName (or use @OnEvent
annotation). Here's some abbreviated code:
@InjectComponent(fielda)
private TextField fieldaComponent;
@InjectComponent
private Form formComponent;
...
Object onValidate() {
If (fielda == null)
formComponent.recordError(fieldaComponent, Example error
message for fielda);
if (fielda==) (fieldb== || fieldc==)
throw new RuntimeException();
return null; // this will keep you on the same page
//return NewPage.class; // this will goto the NewPage page, etc.
etc.
}
You may just want to provide a validation message. I've shown an
example using fielda in the preceding code.
Read the docs on the Form component, and see the examples in the user
guide.
Cheers

Subject: cross field validation with empty fields
Sorry to ask for this again, but I have seen no answer.
I will get no answer again I will stop asking for this, of course.
TIA
Hello, we are using T4.1
We have to validate a form and we don't want to do it client side.
Let say we have three text fields.
The validation should implement the following rule:
if (fielda=) (fieldb= || fieldc=)
then throw new Exception();
The problem is that we cannot link the validation to neither field
because they can be empty and the custom validator we are trying to
implement is nevere called if the field is empty.
We tried to follow the Identity validator but it is also not called
when the field to which is associated is empty.
Is there another way to accomplish cross field validation ?
It seems to us that in T4.1 lacks a validator attribute for the form
component.

RE: cross field validation with empty fields
All very good comments Luther (np about the name :)) and everyone else.
Here is 4.0 code that does the same thing:
public void onFormSubmit(IRequestCycle requestCycle) {
IValidationDelegate delegate = getDelegate();
// this checks if the automatic validations you have on your
// fields (like required) have recorded any errors;
// if they have you can skip your manual logic
if (!getDelegate().getHasErrors()) {
// whatever test you want to make on the field value
if (fielda == null) {
delegate.setFormComponent(getFieldaComponent());
delegate.record(Example error message for fielda);
}
// you can throw from here if you want
if (fielda==) (fieldb== || fieldc==)
throw new RuntimeException();
//
// you can use the requestCycle to forward to other pages
// or throw a RedirectException
}
}
I just thought the poster might still be pondering what to do in T4.

Elmer

Hi all,
Prior to 5.1 in places I used the prefix inherit: in my templates which
seemed to work quite well. Although it is not listed as a standard binding
prefix, it is used as a special case... a mention of it is made here:
http://tapestry.formos.com/nightly/tapestry5/guide/parameters.html
In 5.1 it seems that it no longer working as I expected, I get the feeling
I should no longer be duplicating the property in parent and child, but I
have looked through the release notes but could not find any clue as to what
may have changed.
I also noticed this:
http://tapestry.apache.org/tapestry5.1/apidocs/org/apache/tapestry5/annotations/Component.html#publishParameters(),
so I am wandering what the correct approach is now.
Here is an example for clarity. In my containing component is the
following method, which is also duplicated in the child component:
@Parameter(name = contextVariables)
private List? contextVariables_;
And then I have for example in my tml:
t:header contextVariables=inherit:contextVariables/
So I could propagate these parameters... I also use a custom annotation to
bind these parameters whenever I need them, for example I have a bread-crumb
component that uses them as follows:
@Target(TYPE)
@Retention(RUNTIME)
@Documented
public @interface ContextVariables { ... }
Any help on fixing this would be greatly appreciated!

a href=URLactivateZone/a
Generates:Javascript:
1) setup a ZoneManager against the div#zoneId
2) setup a click listener on the actionlink.. to fetch actionlink URL
from tapestry, (which calls the event listener which returns a Block,
and then tapestry renders block.. ), once the URL returns, it squirts
the contents of the results into the appropriate div#zoneId.
step 2 is basically what Tapestry.activateZone would replace.. so you
can do this without relying on an actionlink or form..

Re: [T5] Tapestry on GORM. It works!
Sorry, the direct link missed out the references on which I built, since they were only in the the teaser on the mainpage. I added them now to the top of the main article, too. Without this blogentry: http://www.rimple.com/tech/2009/02/25/building-standalone-gorm-applications-in-maven/ it would have been a real PITA. My main contributions are only the pointing out that you need to use tapestry-spring and the integration of the tapestry source package into the plugin config. Just setting the credits straight.

Re: [T5 5.0.18] java.lang.IllegalStateException: Cannot create a session after the response has been committed
Peter, returning true works, but it does not redirect the user to a
different page than they were on. Normally you want the user to be
sent to a different page if they are in a secure area of the site when
logging off.
I was just able to fix my problem with a similar situation. I was
trying to return my home page as a Class, but Tapestry did not like
initializing the page after the session had been invalidated. To
solve this, I injected the page using @InjectPage, and then used that
value in the method return. The key here seems to be getting the page
initialized before the session is invalidated.
Now for Harald's case, this might be difficult to implement. It looks
like he's got a dynamic start page that he wants a user to be returned
to. Somehow he's going to have to get an instance of the page and
return that, instead of returning a URL. I'm not quite sure how to do
that here, but maybe someone else can chime in.

Subject: Re: [T5 5.0.18] java.lang.IllegalStateException: Cannot create a

I have a filer to trim off the long jsession IDs from url
You can do so, but IMHO that should never be necessary, the session id is
encoded into the URL only once, and then removed by the container (that is if
you have cookies enabled in the browser). It provides a backwards
compatibility mechanism and support for devices that can't support cookies.
The only other reason that it might be encoded request after request is if
you are creating a new session with each request (a configuration problem
that can happen for instance when you have a problem with your front end -
Apache mod_rewrite), which is not mapping your cookie correctly to your back
end (Tomcat / Jetty etc).
Returning true is interpreted as a terminator for the request by your
container, false allows the request to continue naturally, so if you call
something like session.invalidate(), immediatly after call return true; to
terminate, invalidate acts like a finalize on the request, so anything that
trys to do something with it will cause an IllegalStateException.
The problem I was having the other day related to lazy loading, after an
invalidate, I could not initialize a new page because a new session could not
be instantiated at that point, simply setting the property before the
invalidate fixed that, the second issue was the use of the Response Tapestry
service rather than HttpServletResponse, where the later cannot be tracked by
Tapestry so there is a timing issue (like a race condition), hence using the
first was the solution.

[T5] Web Service
Hi There, I have a web application written using the Tapestry 5 framework. This allows users to view data stored in an SQL database. I want to write a client Java application that a user will be able to run on their local machine. I want this client side application to be able to communicate and retrieve data from my Tapestry application. (Something similar to an ASP.NET web service) I'm not sure what the best approach to this problem is. Socket programming? Essentially what I want is an interface so that I can access data from my client side Java application. This interface needs to start up with the Tapestry application. Some suggestions/advice/pointing in the right direction would be much appreciated (Connecting directly to the database is not an option).

Re: T5 ConcurrentBarrier / Deadlock
Hi Alex! Thanks for your answer. We run the app on different JVM's (all 1.6, Linux-64Bit, WindowsXP 32Bit, Mac-OS X 64Bit). I do not think this problem is related to a particular JVM version or an thread local problem at all. Maybe deadlock is the wrong word. Because of the fact that the thread which triggers the T5 reload mechanism never returned the whole application got frozen. None of the other threads can pass the ConcurrentBarrier while one thread is initiating the reload. It's not directly related to concurrency like two thread claim the same resources in different order. It's only one resource (T5-releod) but this one is never released as the request never finishes... Jens I also recall the deadlock issues manifested themselves on particular JVM versions which were fixed in the latest updates. Which Java version are you running ? Cheers, Alex Kotchnev On Thu, Mar 5, 2009 at 12:40 PM, mailingl...@j-b-s.de wrote: Hi! We encountered a small problem in the way tapestry detects changes of tml's and classes which causes a server crash: in our special case the request which detected changes used the ConcurrentBarrier write-lock to block all other threads. This is ok as long you guarantee the request will return. Due to a bug in the 64Bit VM concerning regex execution the regex parser went into an indefinite loop. This causes a break down of the tomcat as all other request where blocked when trying to pass the ConcurrentBarrier which was never unlocked as the responsible thread never finished. Same applies for example if you need to communicate to external systems and eg a network/socket problem causes the thread to freeze which also locks the whole server. Is it possible to move the lock/and rereading of tmls/classes to a different thread if changes exist? Means regardless if the request responsible for firing the update ever returns the tomcat remains accessible after rereading? You can argue chances for this are not high, but since SEP-08 we had this trouble two times in production... Before I forget: affected version is T5.0.13. we are currently moving over to T5.0.18, so maybe there is a solution yet?

Technically, you should be able to use the normal encoding of the form

Re: @Meta(tapestry.persistence-strategy=client)
Try providing a custom validation tracker to form.
Form creates one that is stored in the session by default.
I suspect this is where your session creation is coming from.
Note that for validation to work properly, you'll have to persist the
tracker in some form.

Hi,
I am trying to prevent session creation when using forms and in
general. I
searched the mailing list but can not explain why the session is
still being
created. I use 5.0.18.
Index.tml
html xmlns:t=http://tapestry.apache.org/schema/tapestry_5_0_0.xsd;
body
t:form t:id=myform
t:label for=cardNumber/:
t:textfield t:id=cardNumber value=cardNumber
size=20/
input type=submit value=Submit/
/t:form
div${cardNumber}/div
/body
/html
Index.java
@Meta(tapestry.persistence-strategy=client)
public class Index {
@Property
@Persist
private String cardNumber;
}
Even when I remove the @Persist annotation from the cardNumber
property, the
session is still being created. Until I remove the Form from the
template.
I am monitoring session creation with a class in my same test project:
package bb.test.session;
import java.util.Date;
import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;
public class MyHttpSessionListener implements HttpSessionListener {
public void sessionCreated(HttpSessionEvent se)
{
HttpSession session = se.getSession();
System.out.print(getTime() + (session) Created:);
System.out.println(ID= + session.getId() +
MaxInactiveInterval=
+ session.getMaxInactiveInterval());
}
public void sessionDestroyed(HttpSessionEvent se)
{
HttpSession session = se.getSession();
// session has been invalidated and all session data (except
Id)is
no longer available
System.out.println(getTime() + (session) Destroyed:ID= +
session.getId());
}
private String getTime()
{
return new Date(System.currentTimeMillis()).toString();
}
}
and with
listener
listener-classbb.test.session.MyHttpSessionListener/listener-class
/listener
in my web.xml.
Of course Firefox extension FireCookie is of help.
So, is this a bug?
Regards,
Borut

Re: [T5 5.0.18] java.lang.IllegalStateException: Cannot create a session after the response has been committed
Looks like this is a bug in 5.0.18 that has been fixed in 5.1.0.0. See
http://issues.apache.org/jira/browse/TAP5-413 for details.

Peter, returning true works, but it does not redirect the user to a
different page than they were on. Normally you want the user to be
sent to a different page if they are in a secure area of the site when
logging off.
I was just able to fix my problem with a similar situation. I was
trying to return my home page as a Class, but Tapestry did not like
initializing the page after the session had been invalidated. To
solve this, I injected the page using @InjectPage, and then used that
value in the method return. The key here seems to be getting the page
initialized before the session is invalidated.
Now for Harald's case, this might be difficult to implement. It looks
like he's got a dynamic start page that he wants a user to be returned
to. Somehow he's going to have to get an instance of the page and
return that, instead of returning a URL. I'm not quite sure how to do
that here, but maybe someone else can chime in.

Subject: Re: [T5 5.0.18] java.lang.IllegalStateException: Cannot create a

I have a filer to trim off the long jsession IDs from url
You can do so, but IMHO that should never be necessary, the session id is
encoded into the URL only once, and then removed by the container (that is
if you have cookies enabled in the browser). It provides a backwards
compatibility mechanism and support for devices that can't support cookies.
The only other reason that it might be encoded request after request is if
you are creating a new session with each request (a configuration problem
that can happen for instance when you have a problem with your front end -
Apache mod_rewrite), which is not mapping your cookie correctly to your
back end (Tomcat / Jetty etc).
Returning true is interpreted as a terminator for the request by your
container, false allows the request to continue naturally, so if you call
something like session.invalidate(), immediatly after call return true; to
terminate, invalidate acts like a finalize on the request, so anything that
trys to do something with it will cause an IllegalStateException.
The problem I was having the other day related to lazy loading, after an
invalidate, I could not initialize a new page because a new session could
not be instantiated at that point, simply setting the property before the
invalidate fixed that, the second issue was the use of the Response
Tapestry service rather than HttpServletResponse, where the later cannot be
tracked by Tapestry so there is a timing issue (like a race condition),
hence using the first was the solution.
Cheers,
Peter

I'm also getting an exception after a session.invalidate() from an
ActionLink and can confirm that it works in Jetty but fails in Tomcat.
It would be nice to know if there is a workaround. Here's the
exception:

Re: [T5.1.0.0] Loop in Form problem introduced in T5.1.0.0
Hi, In your case, why not have a try on AjaxFormLoop component, but I haven't tried this component yet and don't have much experience. Loop component in form is a bit tricky. Set volatile='true' means you need have your source object unchanged. But you have deleted one row during process, so exception happens.

I added the param but now get a new Exception (see below). The exception still only happens when elements are removed from the Loop through AJAX, adding all works fine. This whole volatile concept is a bit fuzzy to me and scanning the source of the Loop component does not clear things up to me. Do you have any further pointers?
