Hi Peter,
Thanks for that. To try it I guess I have to upgrade to 5.0.17 ?

Ironic that you are pointed to yahoo for a solution when the advice they
advocated to the community is to load scripts after markup, all for the false
hope of a performance increase, which is ultimately incorrect and is creating
these types of problems... your markup (hence actionlinks etc) should never be
allowed to render until the scripts have loaded and the DOM is available.
See http://www.quirksmode.org/js/placejs.html at the bottom of the page:
Quote: Placing scripts in the head makes sure that any functions are loaded
before the buttons, links or other things that call them are loaded. If you put
your scripts at the very end of a page, it is possible that a user already sees
part of the page including a button with a JavaScript function call, while the
rest of the page hasn't loaded yet. Result: user pushes button and gets
JavaScript Error Message Alerts, because the browser can't find the script
(yet). Unless there's a good reason to do otherwise, place your scripts in the
head
Fortunately this is now configurable in Tapestry.
public static void contributeApplicationDefaults(
MappedConfigurationString, String configuration) {
configuration.add(SymbolConstants.SCRIPTS_AT_TOP, true);
}
And I bet your problem goes away.
Peter

Russell,
I you look at YUI's event model I belive it handles this better.
YUI Event - http://developer.yahoo.com/yui/event/ will allow you define
events before DOM Ready and queues them until after.
This should be a good way to solve this problem.

RE: T5 5.0.15 possible bug with forms with context on secure pages?
Still, this sounds like a potential problem, because the page will not have been activated, so it's hard to expect it to passivate itself. Does this mean I should raise a JIRA about this? More importantly shouldn't a form on a https page have https as the protocol in the action (that would solve the problem completely since there would be no need to redirect and therefore no need to create an onPassivate event to create a page render link)? I'm not sure what your response means: are you acknowledging a bug in the t:form component and the RequestSecurityManagerImpl and saying that 5.0.16 hides it a little so that there is no exception?

T5 5.0.16 @Paramerter and @Property on same field
Hi, With the change in 5.0.16 that means it fails fast if you have both @Property and getter and setter for a field we have removed quite a few @Property annotations as we realize some fields were silently ignoring the existing getters and setters (which sometimes have a tiny bit of logic in). The odd thing is that now we are getting an exception. Does @Parameter transform a field into a final field now? I don't see any reference to same in the release notes. The exception has at its root: Caused by: org.apache.tapestry5.ioc.internal.util.TapestryException: Binding LiteralBinding[cssClassName: slotCta] is read-only. at org.apache.tapestry5.internal.bindings.AbstractBinding.set(AbstractBindi ng.java:45) at org.apache.tapestry5.internal.structure.InternalComponentResourcesImpl.w riteParameter(InternalComponentResourcesImpl.java:329) I am was advising the team in general not to use @Property any more due to the nature of the gotchas but this would rather put a hole in that. I prefer handcoded getters and setters to simplify unit testing... Any ideas? Many thanks is advance Russell

T5: component gets access to Page Context
Hi, If I have a component in a page and I want to get to the pages context is the ONLY way to have the page pass the pertinent context information to the context as a parameter? What if there component is nested further down the tree? Will a context info I need to be passed through parent components? Even if it is irrelevant to them, or is there some direct way of accessing the containing page's activation context (without injecting the request and hacking it out of there)? Cheers Russell

RE: Deep linking to tapestry pages from jps. Conversion
Hi Borut, We are migrating a Struts app at the moment so if you have any specific questions about stuff then fire away as we _may_ have solved one or two problems that you might face already. Such a guide would be a good idea: it is ideal to start a nice new app with a nice new framework but in the real world most people are working on legacy applications and migration is the normal use case. If T5 wants any real penetration then thinking about migrating users from Struts to T5 is a must. Although it is essentially a marketing problem and most developers struggle with marketing.

Regards, Borut 2008/10/24 Howard Lewis Ship [EMAIL PROTECTED] For deep linking purposes, could you pass the information as normal query parameters? You could then @Inject the Request object to retrieve those values. You can also use the ContextValueEncoder service to decode them to appropriate types.

I would really appreciate it if someone could indicate the rules which are used when forming these urls or if someone could suggest an approach to generate these urls. Possibly a reverse @Inject of the relevant Tapestry object into my Spring service where I could call a method to convert the context values. Thanks, Ian -- Howard M.

RE: T5: class used as value in t:loop must implement serializable?
Answered my own question: further up the stack is a t:form component. This component has found itself nested in a t:form component so in this instance then the answer would seem to be yes. Thing is, right, unless you *know* for a fact your component won't be nested in a t:form somewhere down the line you must make sure that your component nests a t:loop that everything within the loop is serializable? Is that right?

RE: tapestry 5 without sessions
One thing to notice is that a form component has a validation tracker
and that is persisted in session behind the scenes. To avoid this we
provide a new validation tracker to every form like this:
Tml:-
t:form tracker=validationTracker t:id=mySessionlessForm
t:blah/
/t:form
Class: -
/**
* This is essentially a hack to stop the session from being
created. HLS told us to return a new
* [EMAIL PROTECTED] ValidationTrackerImpl} per request
*
* @return
*/
public ValidationTracker getValidationTracker() {
return new ValidationTrackerImpl();
}
public void setValidationTracker(ValidationTracker
validationTracker) {
// NO OP
}
That is the one tip I can offer apart from don't use persist, use
onActivate and onPassivate (as other poster said).
If you do come across any other scalability gotchas please post them. I
will do likewise if we discover any as we move forward with our
development.

Subject: tapestry 5 without sessions
I'm about to start a large project and intend to use tapestry 5 but want
to
avoid using sessions due to scalability. The only issue I can see is
losing
form data when the validation fails because of the redirect after the
post.
I've noticed the property
tapestry.suppress-redirect-from-action-requests
but in general I prefer this behaviour so I'd rather not use this if
there
is an alternative. Plus the documentation says 'This option should be
used
with care' which makes me nervous about using it at all.
The only time I don't want a redirect occurring is when validation fails
and
form data needs to be presented back to the user without being
persisted. Is
there a way to do this because being forced to use session just for this
reason doesn't seem worthwhile.
I'm wondering what other peoples thoughts and approaches were to this
problem.
Has anyone used tapestry5 without sessions?
Cheers,
Jack

T5: Access Page context from sub component
Hi, When I have an action link in a sub component I notice that the query string ?t:ac=some/context/stuff/from/the/page is appended to the link target. I'd like to manipulate that very context in my component and so far I have been passing its elements down through a nest of components. Is there a way to access it programmatically without directly injecting the request and grabbing it from there? Cheers Russell

Thanks. I have already. The docs say Allows a render variable of the component to be read or updated. Updated how, when? What is a render variable? A variable in a template without a corresponding property? But I want to SET a property of my component from the template... As far as I can see it is only of use in a loop in which case it is set at the start of the iteration.

RE: T5: equivelent of c:set ?
Ok...an example
In jsp
c:forEach items=${someList} var=myItem
varStatus=counter
c:if test=${!empty someVar}
somemarkup attr=$someVar}/
/c:if
someothermarkup/
c:set var=someVar value=${myItem.myProperty}/
/c:forEach
So in the above example I have a variable available called someVar
that is set to the value of the previous myItem's myProperty value. But
with T5 and the var binding I get THIS iterations value. The SCOPE of
the VAR binding is not wide enough for me. So is there an equivalent in
Tapestry or do I have to create a component and call it like this
t:loop source=someList value=myItem index=counter
t:if test=someVar
somemarkup attr=${someVar.value}/
/t:if
someothermarkup/
t:mypackage.set value=${myItem.myProperty} t:id=someVar/
/t:loop
And then have code like
@Component(id=someVar)
Private MySetComponentType someVar;
And the MySetComponentType is just
Public class MySetComponentType {
@Parameter
@Property
Private String value;
}
But there just has to be a better way. Right?
Cheers for taking the time

Subject: Re: T5: equivelent of c:set ?
if you use the var: prefix in your template you do not need a
corresponding property in your page/component. and you
can use this variable in your template multiple times (as in the
loop example). tapestry will generate a property on the fly
during rendering for this variable.
if you declare your components purley in your template
you can also pass in the parameters it accepts as well.
and it should work with var: variables as well.
eg.
ul
li t:type=loop source=1..10 value=var:index
t:actionlink context=${var:index}link/t:actionlink
/li
/ul
AFAIK you cannot access the value of the var: variables in your
pages or components.
hope this helps... maybe you can post an example... as posted by thiago

You can do that in Tapestry, but you just do it in a different way.
Remember that the page class properties are always available to the
template.

You don't need to create a component from that, just stop thinking JSP

In Tapestry, all the logic is implemented in pages classes, with no

in templates. And this is a very good thing, as the logic is easily
tested
when implemented in classes. ;)
Not tested, but hopefully it will give you an idea on how to do that:
YourClass.java:
private ItemType item;
@Property /* so we don't need to provide the getter and setter, as they
don't have any logic */
private ItemType lastItem;
public ItemType getItem() {
return item;
}
public void ItemType setItem(ItemType item) {
lastItem = this.item;
this.item = item;
}
public List getList() {
return ...; // list to be iterated
}
public boolean isNotEmpty() {
return lastItem != null; // or any other logic
}
YourTemplate.tml:
t:loop source=list value=item
t:if test=notEmpty
somemarkup attr=${lastItem.myProperty}/
/t:if
someothermarkup/
/t:loop
If you don't get it, tell us. :)

Russell,
Are you using a main class to start your app?
If so you need the line
// Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{-org.mortbay.jetty.plus.jaas., org.mortbay.jetty.});
In your class - see http://wiki.apache.org/tapestry/Tapestry5RunViaMain.
The reason is Jetty thinks slf4j is a 'server' class and in line with
the J2EE specification is stops it 'leaking' into web application
classloaders. This line tells it to let it through.
THis only effects T5 pages/components when you are using the
runViaMain method. It won't effect your non T5 classes as they are
loaded in the system classloader. Whereas the enhanced T5
pages/components load in the web class loader.
Thanks

Not sure if this is totally a T5 issue but I am just seeing if anyone has
seen this. I have a page that uses the Form component but when I call the
page I get a ClassNotFoundException for org.slf4j.Logger. Now I know that
the class is on the classpath as I have Struts app running in the same
container and Calling Class.forName(org.slf4j.Logger, true,
this.getClass().getClassLoader()) in a struts action yields a class but the
toClass method in
org.apache.tapestry5.internal.services.InternalClassTransformationImpl
throws a ClassNotFoundException.
If I change the code in that class to use the parent of the parent class
loader then the class is found.
Any ideas? Is this a bug, is there some way to make Tapestry's class loader
aware of the Class?

Now I know that the class is on the classpath as I have Struts app running in the same container and Calling Class.forName(org.slf4j.Logger, true, this.getClass().getClassLoader()) in a struts action yields a class but the toClass method in org.apache.tapestry5.internal.services.InternalClassTransformationImpl throws a ClassNotFoundException. If I change the code in that class to use the parent of the parent class loader then the class is found. Any ideas? Is this a bug, is there some way to make Tapestry's class loader aware of the Class?

RE: [T5] loading tapestry configuration from properties file?
You can write a Property File based symbol provider implementation (or that is what I did). Mine just takes an array of strings (which are properties files on the class path) and loads them into a map. Then your imp los SymbolProvider.valueForSymbol(String) is just yourSymbolMap.get(String). To keep it all Tapestry 5esque I call .toLowerCase() on all my keys before I put them in the map and toLowerCase() on the symbol I am looking up.

Hi, I know Tapestry5 really pushes the convention-over-configuration approach, but lets face it - in every non-trivial application you eventually need to configure stuff. If not directly tapestry-related properties, then at least your application. By default, Tapestry seems to suggest that everybody should start using web.xml for all such configuration purposes. At least that's the impression that I get when looking at http://tapestry.apache.org/tapestry5/guide/conf.html. However, I don't particularly like the overly-verbose web.xml style of configuring plain-simple properties - I'd rather use (the much more concise) properties file syntax for that. Is it possible to tell to Tapestry: please load all properties from WEB-INF/myapp.properties? If not, can someone give some pointers on how to implement it? (it would also be a welcome out-of-the-box addition to Tapestry5) Rgds, Neeme - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I still think you need to T5-alize it and make it case insensitive. And why oh why oh why bury your exceptions and just log them? Why not let them bubble up so that they are thrown?

What 'it'? You mean symbol names? Well the 'it' was the class, or moreover the approach but that does result in specifically the symbol names in this instance, so: Yes that it, or they. Because That's the Way I Like It! :-) Seriously, I struggled with myself about this and decided that in my case it's better to have the application start up and fail later IF a missing symbol is requested. Fair enough then. I did it differently (since I'd like to know at start up if my app is miss-configured), I guess the solution needs to fit the requirements.

RE: T5: testing using PageTester and EasyMock
Hi Alex,
Testing pages as POJOs is quite simple. You can roll your own very,
very, very simple service injector and inject EasyMock services into the
pojo. I have done it using reflection. So I have a class that takes the
page instance being tested in the constructor (and the test class too)
and for each field annotated with @Inject it creates a strict mock and
sets the field to that value. It also adds the mock to an internal List
if mocks. Then the class provides convenience replay, reset, verify
methods that iterate over the whole list. The test class also has fields
that use a custom annotation (@Mock) these are injected with the same
values as those added to the page under test. So you end up with a test
class with populated mocks, a page class with populated services and a
helper class with the same mocks held in an iterable fashion for
convenience.

Subject: Re: T5: testing using PageTester and EasyMock
I was grappling with this issue myself, I still don't have a good answer
to
it. Because T5 is so heavily annotation driven (with the IoC and the
framework doing a lot of the magic heavy lifting behind the scenes),
testing
the pages as POJOs (e.g. setting some properties, performing an action,
inspecting the state of the page) is not immediately obvious.
I've looked through some of the T5 unit tests (w/ EasyMock), and often
times
a page has a special (e.g. package private) method to inject services
that
otherwise the framework would inject. So, for example, if the page used
to
have an :
@Inject
FooService fooService
@Inject
BarService barService
Then, the page class would usually have a package private method like
this :
void setServices(FooService fs, BarService bs) {
this.fooService = fs;
this.barService = bs;
}
Anyway, there certainly is room for improvement, most advanced web
framework
have a way of testing pages/components as Pojos. Although the solution
above
works OK (and if you think about it, it's still pojos), it certainly
isn't
the first thing to think of once you get used to having Tapestry
injecting a
bunch of things into your pages. From a conceptual point of view, when
you're *unit *testing a page, you really DON'T want to have the real
services injected, and you'd probably just want to have
mocks/stubs/fakes in
their place that return the data needed to unit test the page. Now, if
you
were doing more of an integration type of test (e.g. where you test
how
the page works with the *real* service), then it's a different ball
game,
you do need the real services injected (for which you can still use the
above approach and not depend on the IoC to do it for you).
I guess the alternative would be to have a test context for binding
test/mock instances of the dependent services and somehow ask T5 to
inject
them into the page being tested. But then, it wouldn't really be unit
testing as the tests would depend on a whole bunch of things other than
the
unit being tested.
Let's keep this discussion rolling, we certainly need a little more info
on
testing in T5.

Thanks for that. That is just normal EasyMock testing isn't it? I don't see

the classes and you are creating the instance of the class under test aren't
you? Where is the PageTester and Tapestry IoC and all that (or have you missed

What I meant was this:- In the src/main/java tree I have MyAppModule which has
some services like
Binder.bind(MyService.class, MyExpensiveExternalImpl.class)
But in my src/test/java tree I have
@SubModule( { MyAppModule.class })
MyAppTestModule
public static MyService buildMyService () {
return EasyMock.createMock(MyService.class);
}
(In the actual App the MyService Impl will be provided by Spring but that is by
the by)
So that when I use PageTester in my tests I can go
MyService myMockService = pageTester.getRegistry().getService(MyService.class);
EasyMock.expect(myMockService.expensiveExternalMethodCallToCreditCardGatewayIdontReallyWantToTest(myCardNumber)).andReturn(authCode);
But the problem is...the registry returns a Proxy that contains a
JustInTimeObjectCreator so EasyMock won't have no truck with my mock service.

Yeah. I think that the approach you outline may well work but is
unworkable (if you know what I mean). I hold out for some way of
stripping the proxy from my mock service (using reflection to fire the
Object Creators create method and using the un proxied mock).
The problem with training the mock in the test case is that you don't
get the mock from the registry, you get a proxy wrapped mock.

Hi Kristian,
From your post I inferred that you have integrated Spring Web Flow and

tapestry 5 pages as the views but still using Spring WebFlow FormActions
for the actions? Did you have to write a custom View Resolver? Did you

integrate launching and ending a flow from a Tapestry request?

hi lubor,
IMHO, there is a much simpler and more elegant solution:
in order to save my data in a conversation state object i wrote
a decorator for the PersistentFieldManager intercepting every

define an own persistence strategy @Persist(conversation)
as well :)
I'm no native speaker but ApplicationStateObject is quite fine for

Re: T5: ApplicationStateObject is misleading
Hi Geoff,
I absolutely agree with you that concept of ASO objects and persistent
properties is one of few downsides of current Tapestry implementation. I
came across this type of problems recently when I was experimenting with
Tapestry Spring Web Flow integration.
One of the issues that I had to solve was to find simple solution how
from
tapestry pages access objects stored in different webflow scopes. To
achieve
this goal I couldn't use neither persistent properties nor ASO.
Persisted
properties can't be shared between different pages in the same flow and
ASO
objects require additional configuration if you want to use non default
persistence strategy (to complicated solution). Therefore I was forced
to
develop my own solution which is based on my custom ScopeWorker that
allows
page properties to be annotated by my custom @Scope annotation:
public class MyPage {
@Scope(SESSION)
private User user;
@Scope(FLOW)
private Facility facility;
...
}
@Scope annotation can be used with different scope types (APPLICATION,
SESSION, CONVERSATION, FLOW, FLASH, PAGE, REQUEST, etc.) to access
objects
stored in these scopes (when object is not found in the scope it's
automatically created).
I think that it would be good idea to find (in some future Tapestry
release)
simple generic solution for scoping page properties that would replace
currently used ASO and Persist strategies (these could be marked as
obsolete
and kept for backward compatibility reasons).
Regards
Lubor

One term that I believe many people find misleading is
ApplicationState.
The problem is that it implies it will make an object available
across
the
whole application, ie. application-scoped; which is not its purpose.
The doco says that ASOs are unique to an individual user, not
shared
between users, which is not quite right, either.
The standard usage is to tie an object's scope to that of a web
session,
so
maybe we should put session in the name? Eg.
@SessionScoped
@SessionShared
@ShareAcrossSession
It is important to understand that the term session here is NOT a
reference to the persistence mechanism, but a reference to the
scope.
Alternatively, let's keep it really obvious with this:
@StateObject
with the understanding that the default persistence strategy is
session.
What do others think? Are you happy with ApplicationState?

RE: pageLink and a context
Do you not just need to use literal: prefix on your string? Otherwise Tapestry assumes it is a property.

So, what I was doing here was something like: .../project?create .../project?search But - I'm guessing I shouldn't even be doing this. I should just go to project/create and project/search and then piece together the components. I shouldn't even try to share things like a controller because it just doesn't work that way.

I really haven't given much thought to the topic, as it seems that it's quite far away in the future. Also, not to diminish the importance of the index; however, at this point, it is not very clear exactly what the printing options for the book are going to be (e.g. purchase on lulu, print a pdf on your own), and it's not even a proper technical book yet (e.g. no publisher or anything like that). So, once again, the index is very much in the future.

The Kolesnikov Tapestry book has one of the worst indexes I've ever come across and stands as a good example of how not to do it. Having a good index is a very important part of any successful technical book. Indexing a book well is a non-trivial matter and shouldn't just be a last minute thought. I'd also suggest a good set of Appendices - one, at least, should list the components and what parameters they take. Anyway, something to think about. p. Quoting Alex Kotchnev [EMAIL PROTECTED]: I've created a new project for the proposed book at http://code.google.com/p/tapestry5-book , and posted the proposed table of contents at http://code.google.com/p/tapestry5-book/wiki/ProposedTableOfContents . Now that I'm looking at it, it's a little disappointing as the TOC doesn't really have anything new in it (e.g. some of it is covered in tutorials, other is in the project docs, etc). However, I guess that the content really can't be all that different - it's all about building web apps, covering the same materials as the other documentation. In the end, I think that the book will be different from the other existing documents based on its style and breadth of content, and not so much in the topics it covers. Anyway, I would like to create a mailing list and add everyone who has expressed an interest in contributing to the book. Unfortunately, Google Code doesn't have mailng lists, so I'll probably have to look around for that (Nabble, maybe?). Any suggestions would be welcome here. In terms of moving the proposed TOC forward, here are some of my next steps : 1. Attribute the main sections of the project documentation into possible chapters in the book. 2. Discuss feedback from this list on the content of the proposed TOC : e.g. any alternative ideas on how to organize the book, changes to the proposed chapter titles, order, etc. It would be great if there are any volunteers to investigate some of the issues that were discussed previously in the thread below, I'll probably post the needed tasks somewhere on the wiki as well. When we get our mailing list set up, I think that individuals or groups of individuals can claim ownership of each chapter (and thus get voting rights on the TOC, chapter layout, further modifications, etc. Cheers, Alex Kotchnev On Thu, Aug 28, 2008 at 4:59 AM, Hugo Palma [EMAIL PROTECTED] wrote: inline Alex Kotchnev wrote: Would there be any value to having a top-level domain for the book (e.g. tapestry-book.org or something like that), or can we find it a home for the book somewhere under the Tapestry namespace ?

Then, we can collect a first set of volunteers for people take ownership of each chapter. After the initial set of volunteers, the chapter owners will vote on addition of new chapters and giving ownership of chapters to new contributors (if needed). Shouldn't the outline be already created in a tapestry-book wiki ? We could decide on where to host it and then move the discussion to the dedicated list and use its wiki for the outline. On whether the book would cover additional libraries (e.g. chennilekit, t5components): I think that after we get to a good place where we have enough content on the core we can probably spend some time on those as well, possibly with contributions from the project owners.

RE: T5: Service disambiguation
Thanks. That isn't what I originally implemented but it will do the job
just as well.
My problem is/was that SecureCookiesImpl uses the Cookies service as a
delegate (the constructor expects Cookies as a parameter) but doesn't
extend CookiesImpl...although it could. That would be one solution. I
wanted a SecureCookies service and a Cookies service, but the IoC sees
that as two Cookies services.
Like I said, I just de-OO'd it (no interface inheritance, no
relationship, SecureCookies is a separate unrelated interface and
SecureCookiesImpl is unrelated to and no longer delegates to Cookies and
I just inject *both* services) I would still like to know if this sort
of thing is possible. I think the autobinding of PersitantLocaleImpl is
the problem. Is there any way for me to disambiguate which Cookies
service it requires in its constructor?
However this is an academic issue now since both of the solutions above
(mine and Filip's) satisfy my requirements.

Hi,
You have to alias the Cookies service.
public static void bind(ServiceBinder binder) {
binder.bind(SecureCookies.class,
SecureCookiesImpl.class).withId(SecureCookies);
}
public static void
contributeAliasOverrides(ConfigurationAliasContribution configuration,
@InjectService(SecureCookies) SecureCookies secureCookies) {
configuration.add(AliasContribution.create(Cookies.class,
secureCookies));
}
SecureCookies extends Cookies, SecureCookiesImpl extends CookiesImpl and
implements SecureCookies.
I just tried it out and it worked for me on Tapestry 5.0.13.
Hope this helps.

RE: Class not found exception
Hi,
I asked about this a few weeks back and Ben Gidley pointed me at the
wiki with these words
What is happening is Jetty hides 'server' classes from the web
application unless they are also in WEB-INF/lib. When you run in the IDE
you don't have a WEB-INF/lib so it can't find the slf4j classes as they
are loaded by Jetty as server classes.
You are starting Tapestry inside your IDE using a Run class - you need
to add a line into your startup class saying
// Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{-org.mortbay.jetty.plus.jaas., org.mortbay.jetty.});

Hi,
I asked about this a few weeks back and Ben Gidley pointed me at the
wiki with these words
What is happening is Jetty hides 'server' classes from the web
application unless they are also in WEB-INF/lib. When you run in the IDE
you don't have a WEB-INF/lib so it can't find the slf4j classes as they
are loaded by Jetty as server classes.
You are starting Tapestry inside your IDE using a Run class - you need
to add a line into your startup class saying
// Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{-org.mortbay.jetty.plus.jaas., org.mortbay.jetty.});
see http://wiki.apache.org/tapestry/Tapestry5RunViaMain for more
details.
Hope that helps

I see this has been raised before and is supposedly a Jetty Error.

RE: Class not found exception
I don't think run jetty run supports configuration by a jetty.xml. The
author says in his Usage instructions
There aren't many options, just the web application directory, the
context and the port. I intentionally keep it basic so that it will be
easy to use and maintain; if you need anything more fancy, use one of
the other Eclipse app server plugins, or do what I often do: create a
start up class in your project.
Not sure where that leaves you. Sorry I can't be more help. The basic
problem is the same. You need to tell Jetty that you don't want it to
hide the slf4j server classes. One way of doing that is setting the
ServerClasses property as Ben did below. How you set that property with
run-jetty-run is beyond me. Sorry.
If you look at the wiki post linked to in my post you can just cut and
paste the code into a run class and you will be up and running very
quickly indeed. I agree with your shoulds...but maybe ditching
run-jetty-run would help.
Cheers

Russell,
I think this is a Jetty issue. Try running the application via mvn
jetty:run
- if this works then the problem is Jetty is hiding SLF4J from the
beanEditForm class loader.
What is happening is Jetty hides 'server' classes from the web
application
unless they are also in WEB-INF/lib. When you run in the IDE you don't
have
a WEB-INF/lib so it can't find the slf4j classes as they are loaded by
Jetty
as server classes.
You are starting Tapestry inside your IDE using a Run class - you need
to
add a line into your startup class saying
// Remove slf4j from list of classes not exposed to webapp
webapp.setServerClasses(new String[]
{-org.mortbay.jetty.plus.jaas., org.mortbay.jetty.});

PageTester class as described in the documents here
(http://tapestry.apache.org/tapestry5/tapestry-core/guide/unit-testing-pages.html)
when I try to create a new Instance of PageTester.
The stack trace is as follows:--

These lines in PageTestContext seem to be the culprit
public PageTesterContext(String contextRoot)
{
_contextRoot = new File(TapestryTestConstants.MODULE_BASE_DIR,
contextRoot);
}
I looked in the jar and the svn repo and this class (TapestryTestConstants)
is absent.
Any ideas?
Cheers
Russell

Hi All, New to Tapestry 5. I have read the Building Web Apps Tapestry 5 book by Alexander Kolesnikov and am working through the documentation and Wiki too and I have a functional little web app at the moment that took me all of a few hours to build and test so I am very pleased with the productivity. I haven't found how to redirect to an external url though. I think my mind is stuck in Strruts MVC groove after all these years. So I have a Page class and what I want the page to do is check for the presence of an @ApplicationState property and redirect to an external url. In struts I'd have the logic in the execute method of an Action. In Tapestry 5 do I put this code in the onBeforeRender method? And how exactly do I do a redirect to an external url please? I know I am thinking in the action-forward-to-view way and that the relationship between a page class and a page template is not exactly analogous...I think this is conceptually where I am stuck. Not all web apps are about pages so what metaphor is there for requests that aren't page based? My practical problem above stems from current failure to grok the pattern Tapestry 5 implements. Many thanks in advance if you can help (with either my practical or conceptual problem).

Hi Russell,
I do this in the SetupRender phase.
@Inject
private org.apache.tapestry.services.Response _response;
void setupRender () throws Exception
{
if (/* condition satisfied */)
_response.sendRedirect( http://example.com; );
}

Service Configuration, ApplicationDefaults and String parameter in constructor
Hi Again,
Now I have a Service that I want to configure with a string parameter
and an int parameter. I add a couple of values to the
ApplicationDefaults like this:
configuration.add(my.long.key.string-value,
aStringINeedInMyService);
configuration.add(my.long.key.int-value, 180);
And in my service I have a constructor like this:
private final int intINeedInMyService;
private final String stringINeedInMyService;
public MyNewServiceImpl (@Value(${my.long.key.int-value
})
final int cookieAgeInDays,
@Value(${my.long.key.string-value })
final String cookieName) {
this. intINeedInMyService =
intINeedInMyService;
this. stringINeedInMyService =
stringINeedInMyService;
}
}
This seems to work except that the value of stringINeedInMyService is
always the Service's Service Id. I verified this by changing the Id of
the service in the AppModule by calling binder.bind(MyNewService.class,
MyNewServiceImpl.class).withId(MyDifferentId) and behold the value
injected into the String constructor parameter for the MyNewServiceImpl
was the new service Id. Is this expected behavior (IE have I miss
understood how to configure my service)? Or is there something else
going on? Has anyone configured a service this way before?
Many thanks
Russell

RE: Service Configuration, ApplicationDefaults and String parameter in constructor
Ok,
Sorry all. Scratch that. I RTFM. Here
http://tapestry.apache.org/tapestry5/tapestry-ioc/service.html#Injecting
%20Dependencies at the bottom of the page it says
Every once and a while, you'll have a conflict between a resource type
and an object injection. For example, the following does not work as
expected:
It doesn't work because type String always gets the service id, as a
resource (as with the serviceId parameter). In order to get this to
work, we need to turn off the resource injection for the alertEmail
parameter. That's what the Inject annotation does:
Sorry all
Cheers
