Is the Select component's VALUE_CHANGED event out of the scope of user sessions ?
I'm using v5.4-beta-17 and I'm facing an issue. I have an object persisted using the @Persistent annotation. And then I have a Select component on the page. While handling the Select component's VALUE_CHANGED event method, it seems I can't access the persisted object, its always null although I've initialized it in the Form's PREPARE event (This event is fired whenever the form containing the Select component is preparing for rendering\submission) *-* *Muhammad Gelbana* http://www.linkedin.com/in/mgelbana

Exactly. I was thinking of a *submit*. But now that I thought about it, a
submit may not be needed. But I tend prefer having every possible option
available for me to handle whatever scenario I may face. I'll go with the
ajax option. Thank you.

Re: [t5.4-beta-6] Page class member variable scope
Sorry, that sounds very odd to me. "refresh the page without refreshing it"
sounds like a contradiction!
Your Select has made an AJAX request. Why wouldn't you want an AJAX response,
ie. a partial render? If you return the whole page then any other changes on
the client-side will be overwritten, by a server that doesn't know what was
there except for the value of the Select and any context.
Your question is making me think what you really want is to trigger a submit of
the enclosing form when the Select value changes. That way the server-side will
get the whole picture and be able to do a suitable non-AJAX response.

Re: [t5.4-beta-6] Page class member variable scope
Its ok to use Ajax, but is it the only way to update the page after a
value is changed in a Select component ? If yes, wouldn't it be an
improvement to be able to refresh the page without refreshing it and
losing its state ?

Re: [t5.4-beta-6] Page class member variable scope
By returning "this" you're doing a page refresh, which is an HTTP 302 redirect,
instead of an AJAX response.
The redirect causes the browser to issue a second request - a fresh page
request - which will be freshly rendered by your stateless page class without
any knowledge of the value you set in the previous request. You can see the 302
response and the second request with the browser's web inspector or firebug.
Here's a working example:

[t5.4-beta-6] Page class member variable scope
I hope I selected a valid subject !
When I handle a VALUE_CHANGED event for a Select component. I receive the
current value for the Select component as an event handler method parameter.
I use this parameter to set a member variable in the page's class.

What I'm facing there is that *this.parameterType* is always null and never

I understand there could be other ways to achieve the same behavior but why
isn't this behaving as I expect ?

Hello I'm looking to build a service where I would be Injecting a hibernate
session as well as synchronizing a few methods for multi threading. I'm
confused as for when I should be using the PERTHREAD scope.
Scope(ScopeContants.PERTHREAD)
public class MyServiceImpl.class implements MyService {
private static final Object lock = new Object();
private final Session session;
public MyServiceImpl(Session session) {
this.session = session;
}
public void getLogicMethod(String value) {
synchronized(lock) {
//session do something
}
}
}
//Stateless Impl Example
public class MyServiceImpl.class implements MyService {
private final Session session;
public MyServiceImpl(Session session) {
this.session = session;
}
public synchronized void getLogicMethod(String value) {
//session do something
}
}
If I were to use the second example, would the getLogicMethod be
synchronized across threads while being called from another service?
Thanks Guys,
Re: @Scope PerThread may cause PermGen errors?
Yes, as I said the annotation was just there by accident.
But thanks for making it clear.
I guess using ObjectLocator.proxy has the same effect? One has to be careful
not to misuse this feature.
Well, Howards, thanks for taking the minute :-)
I already had a peek at the latest 5.4 code and even got a small test-app
running without problems so far. Great job!

Re: @Scope PerThread may cause PermGen errors?
Per-thread scope means to create a new implementation, via the builder
method, once for every request: buldUserCacheSupport() is invoked the first
time any method of UserCacheSupport is invoked.
EnvironmentalBuilder creates a proxy class and instance, and is intended to
only be invoked once per service; that is, a singleton service. Since it
is being invoked multiple times, it is creating one proxy class after
another, and these are accumulating in PermGen.
There is no need to make UserCacheSupport per-thread, since everything in
the Environment is already per-thread.

@Scope PerThread may cause PermGen errors?
Hi everone,
today I found the reason for a recent memory leak and I thought I'd ask what
you think of it:
Rather by accident I annotated one of the EnvironmentalShadowBuilder-methods
with @Scope(PERTHREAD)
@Scope(ScopeConstants.PERTHREAD)
public UserCacheSupport buildUserCacheSupport() {
return environmentalBuilder.build(UserCacheSupport.class);
}
(UserCacheSupport is just a custom environmental)
So I removed the annotation and everything is ok again.
But: Isn't that strange? Is that a known behavior? Using jhat I found thousands
of undead UserCacheSupport classes tied to a PlasticClassLoader. So Plastic
creates one class per request (i.e. per thread) and.. somehow keeps it. Without
the explicit @Scope setting there should also be one new object per thread, but
it does not cause a leak (since there's not a new class for each request, I
guess). I'm wondering if it's actually a bug in Tapestry?

Tapestry/Hibernate/Quartz/Perthread scope
Gratefully wondering if someone could validate my hunches about Tapestry. By way of background, I've got a Tapestry app that manages some training data for a machine learning process. The training process is time consuming, so I want to do that outside of the request/response cycle. I intend to have "training data changed" events dropped onto a message queue (just a shared, thread-safe queue) to a Quartz job. It wakes up from time to time, checks the queue, and returns the results of its calculations the same way (via a different queue). My sense is that the right way to go about this is to inject the HibernateSessionSource into my quartz bean, but manage transactions and close the session manually. Via tapestry-quartz, I could use Tapestry IoC to get the HibernateSessionSource into my quartz bean, but using @CommitAfter within my quartz bean is pointless since nothing will be setting up the quartz threads with Hibernate sessions, nor cleaning them up afterwards. Alternately, I'm wondering if there's some way to enrol quartz worker threads in Tapestry's notion of 'work-doing' threads, in a way that would cause whatever existing plumbing (e.g Hibernate) to work magically. Is this what PerthreadManager.run() is about? Can I just hand it a Runnable and (by virtue of the existing configuration provided by tapestry-hibernate) those runnables can @Inject a Session?

I wouldn't worry about it; there's a lot of caching going on inside AssetSourceImpl.

PerThread Scope and Assets
Hello, first of all i am very glad to go back to work with T5 :) I was missing the mailing list. :) I know the PerThread scope service are created per request, but i don't want the object to be created for every asset that is loaded, i only needed for the PageRender cycle.

Re: @Scope
Tapestry's style of injection is somewhat orthogonal to Spring's. Tapestry will want to create a proxy and, with a contribution like Thiago says, instantiate a new instance for each method invocation. That's probably not what you want, in which case, you should use an explicit factory service, so you can ask for a new instance when it makes sense.

Re: @Scope
Hi, you can inject ObjectLocator and call 'autobuild' to create a new instance when needed. So instead of @Inject private MyService myService; ... myService.doSomething(); you would have @Inject private ObjectLocator locator; locator.autobuild(MyService.class).doSomething(). However I am not sure if your design is correct - do you need really to save state in the service? It does not look like a proper service.

@Scope
I have a service, that I need a new instance of every time it is referenced. In ScopeConstants I see DEFAULT, and PERTHREAD. I really need a new instance every time I request this particular service because it saves state, and yes, there are some occasions where I need several of these in the same thread (web request). For now, I can change all of my references to the service to a new instantiation of the implementing class, but that really isn't ideal. Does anyone have any idea how difficulty this type of change might be, and if it might be possible to get it into a 5.3-beta?

Re: component scope service with injected messages
As a side note: in 5.2 you CAN inject a Messages object at the service
layer ... this Messages object provides access to the application's
global message catalog (i.e., WEB-INF/app.properties). It's a proxy
Messages that internally determines the current Locale and delegates
to the correct localization of the global message catalog.

Hi all, I am aware that there is something special about tapestry services/resources such as Request, Messages etc which are only available in the context of a component render. I need to create a service which makes heavy use of the messages store and is available only in the scope of a component render. Can someone explain how I can configure this service correctly so that I can create it with the appropriated Messages object each time it is used?

Re: Tapestry IoC: Bean Scope
Unfortunately, Tapestry is not Spring :-) The proxy you get back from a direct or indrect call to getService() is always global, though in the case of the perthread scope, that core service implementation is ... another proxy that manages and delegates to the per-thread instance. I think you need to use an explicit factory if you want to control when new instances are created. In fact, for ordinary beans, you can get the BeanModelSource, get a BeanModel for a class, and use its newInstance() method. However, that's roundabout, because newInstance() gets the ObjectLocator (which can be injected into any service) and invokes autobuild() on it ... so it's a very generic factory.

Tapestry IoC: Bean Scope
Hi all, is it possible to have services bound with Bean scope? I'm using Quartz scheduler and my jobs are actually services bound in AppModule with all dependency injection and so on. But i want different instances of jobs. So every time i call ServiceResources:getService(..., Job.class) i want new instance back. I remember it was not possible to implement with Hivemind, how about Tapestry-IOC? Thanks.

Advising a Scope PerThread Services with Context
Hello everyone. I'm new here, so let me just say hello. I'm rektide, I've been using Tapestry 5.1 since July 2010. Been mostly great, with the main caveat being trying to figure out how to coax my app into having enough context when I run Ajax requests. The component model is awesome, the IOC engine works great, the JS integration is like nothing I've seen & has proved time & time again quite flexible. Good stuff, thanks all. At present, I'm trying to build a MethodAdvice implementation that modifies the behavior of a PerThread Scope'd service. The MethodAdvice needs access to the public members of the Service to perform this advising. I cant find any way to get the Service instance from inside the MethodAdvice. The module that fires the MethodAdviceReceiver can be injected in to, but this is a one time initialization action: it rebuild the MethodAdvice per-request. I've tried various injection annotations in the MethodAdvice itself, but havent had any luck. Is there some programatic means of requesting a Service that I can run inside the MethodAdvice to pull out the current instance of my Service? As a note, it would be awfully handy if Invocation had a getThis() method! Or if the advise method had a second parameter to provide that context! Any suggestions for now, on how to get the Service being advised from within the MethodAdvisor?

Re: RenderSupport Scope
If you want to declare a global function from within Tapestry.onDOMLoaded, you
can simply add it to the windows object:
window.myGlobalFunction = function() {
doCoolStuff();
}
You can then access that function from anywhere if you prefer to do things this

Re: T5: Testing service scope
Thanks anyway :)
I guess integration tests on a real registry will be put on hold for now
then, since the only viable solution is to implement stubs for some
services, which makes me unable to mock and verify their behaviour, which
limits my tests quite a bit...
I find integration testing in Tapestry 5, both pages, components and
services, to be quite hard in general. Our system has a lot of spring beans
injected as well as T5 IOC services, so there is a lot to take care of in my
test registry before I can actually get some testing done on my pages. Lots
of database and filesystem stuff that needs to be mocked/stubbed in a
meaningful and mantainable way. But I'll continue trying to find an approach
that makes sense :)

Re: T5: Testing service scope
Ah - OK. I don't think there's an easy way to do this at the moment. The
obvious way is to either use the registry with real dependencies or else
create a TestModule to fake the dependencies (but you have already
discounted this approach).
I've been toying with this kind of functionality for Testify, but there
are no easy hooks into the registry creation process that would let me do
it. I do have another ingenious idea though :-)

That's what I'm already doing. This time I wanted to test that the perthread
scope of my service worked like it should, that's why I need to do an

Re: T5: Testing service scope
Hi Inge,
Testify doesn't support overriding services actually within the repository
(currently, it make components check for overrides before going to the
registry - hence the annotation name @ForComponents).
However, would a simple unit test of the service do the trick for you? In
other words, just create the ModuleOrderProvider by hand, passing in the
mocked/faked dependencies :
ModuleOrderProvider u = new ModuleOrderProviderImpl(settingsFacade);

Re: T5: Testing service scope
Ok, so now I need to mock one of the dependencies of a service I'm testing.
I realized that I don't know how to do that when I manually created my
registry. I don't want to have a "TestModule" that builds fakes for my
external dependencies, in this case it is enough to just mock the service
that provides configuration values.
Then I tried using testify, like below, but Mockito claims that my
"settings" service is not a mock, so I guess testify isn't built to support
this kind of mocking... Any ideas?
@Mock
@ForComponents
private SettingsFacade settings;
@Test
public void settingValueIsCachedInThread() {
when(settings.get(MODULE_ORDER)).thenReturn("module1,module2");
ModuleOrderProvider u = tester.getService(ModuleOrderProvider.class); //
This service dependes on the SettingsFacade service
u.getOrder();
u.getOrder();
verify(settings.get(MODULE_ORDER), times(1));
}

Querying the registry for the same service from different threads should yield different instances when using the perthread scope. Just test that.

Re: Why does Registry.get(Class, AnnotationProvider) ignore @Scope?
Well, actually it does compile - if the class is written in Groovy. :-) Have
to investigate this further. Anyway, I now understand that @Scope is allowed
on a service implementation class, but not on its fields. Thanks for the
clarification!
Cheers,
Peter

Re: Why does Registry.get(Class, AnnotationProvider) ignore @Scope?
Hi!
The @Scope can't be used in fields: it wouldn't compile (@Scope is
defined with @Target(value={TYPE,METHOD})). In addition, each service
has only one scope, defined in its builder method. From
http://tapestry.apache.org/tapestry5/tapestry-ioc/service.html:
"Each service has a lifecycle that controls when the service
implementation is instantiated."
"Service lifecycle is specified using the @Scope annotation, which is
attached to a builder method." When this annotation is not present,
the default scope, "singleton" is used."

Why does Registry.get(Class, AnnotationProvider) ignore @Scope?
I'm using Registry.get(Class, AnnotationProvider) to find matching services
for fields of an object that is not under Tapestry's control. Everything
works fine, except that annotating a field with @Scope("myOwnScope") has no
effect. Is this a bug? If not, what can I do to obtain a service with the
requested scope? (Annotating the service builder method with
@Scope("myOwnScope") works as expected, but isn't appropriate in this case.)
Cheers,
Peter

I'd do that with the help of quartz. The third-party component library Chenillekit has support for it IIRC. Also search the list archive (tapestry.markmail.org), there has been some discussion about Tapestry and Quart in the past. And also, I was looking at the ajax documentation. It didn't state whether if the ajax supported is secured or not. I only wanted authenticated user to be able to call the ajax. Is this possible with Tap5 at the moment? Sure. Use the if component and only render ajax-enabled components if the user is authenticated.

T5: tapestry-ioc scope problem in a standalone program
Hello, every one. I met the following problem when trying to use
tapestry-ioc
in a standalone program. According to the tapestry official site, a
service
builder method should be invoked multiple times, if it is annotated with
@Scope("perthread") and the service is used in multi threads. So I wrote
the
following program, trying to demonstrate it. In the program, ServiceA is
used in two threads, but the builder method is invoked only one time. Why?
public class Main {
public static void main(String[] args) {
RegistryBuilder regBuilder = new RegistryBuilder();
regBuilder.add(ModuleA.class);
final Registry reg = regBuilder.build();
final ServiceA a = reg.getService(ServiceA.class);
a.print();
new Thread() {
@Override
public void run() {
ServiceA aInAnotherThread =
reg.getService(ServiceA.class);
aInAnotherThread.print();
}
}.start();
}
}
public class ServiceA {
public ServiceA() {
System.out.println("A new instance of ServiceA is under
construction!");
}
public void print() {
System.out.println(this);
}
}
public class ModuleA {
@Scope("perthread")
public static ServiceA builder() {
System.out.println("Building a new instance of ServiceA ...");
return new ServiceA();
}
}

As I understand it I need to provide a way for Tapestry to convert my DateeeMatch object to a string. The DateeeMatch is too complex to serialise directly in to the page. Is there some way, I can store it in the session, then use some type of ID to retrieve the correct object from the session. I could then just put the ID in the actually URL. Is there some standard way of providing this type of Coercion in tapestry or do I need to implement all storing to and retrieving from the session functionality my self. According to the docs there's a standard Object -> String coercion in built in, I am currently trying to find the source of that to see if that will give me any pointers. Is this the best approach to Coercion of more complex objects (not single data objects like Strings)? Thanks again for the help.

Re: T5: A Hopefully Simple Question About Action Link Scope
The problem is that you must give action link something
to identify your object.
in the page you mentioned you have only one instance of
the MatchInfo component that get's rendered multiple times with different
data.
So when your action is called, you have the last element passed as
parameter.
you shoud link it like this:
Changed Your
Mind
public void onActionFromChangedMind(Long id)
{
//load match from database by the id
System.out.println(match.getName());
}
-
if in you AppModule you make following TypeCoercers :
String->DateeeMatch
and
DateeeMatch -> String
above code can look like this:
Changed Your
Mind
public void onActionFromChangedMind(DateeeMatch match)
{
//load match from database by the id
System.out.println(match.getName());
}

Thanks for your reply however, I don't think was very clear about what
I'm trying to do.
I was trying to avoid posting code from lots of different files but. I
think I can find the relevant snippets, which should make things
clearer.
So here goes:
>From Start.html:
>From Start.java:
@Persist
private List matches;
@Persist
private DateeeMatch currentMatch;
matches is filled from a long DB query.
The action link in MatchInfo.html:
Changed Your Mind
>From MatchInfo.java
@Parameter(required=true)
private DateeeMatch match;
public void onActionFromChangedMind()
{
System.out.println(match.getName());
}
My problem is when you click the action link on any of the MatchInfo
components on the start page. The console shows the name of the last
match not the one clicked on. The MatchInfo component also correctly
displays lots of info from the match parameter, so that is defiantly
OK.
Can anyone shed some light on this for me?

T5: A Hopefully Simple Question About Action Link Scope
Hi All I am currently experiencing a problem which seems to contradict the model of how action link works. I have a page called start.html. It has a for loop which for every iteration contains a custom component, called MatchInfo. This renders a box containing the info about the match. MatchInfo has an action link tag and event method, which does something with the match. The method called by the action link uses the persistent field which stores the actual Match object which the component gets data from. However when ever I use the page and click the action link, its as though the action link is clicked on the last MatchInfo component, even when I click the action link on a different MatchInfo component. I thought the action link would call the method of the component object that generated it not just the last object. I am not sure if this is a bug or a "Feature"? Can anyone shed some light on this for me. Charlie M - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Persisted Object with session scope is getting lost between the pages.
Thanks again. I am trying to implement Master-Detail pages ( Order List -> Item List). On oder List, I am trying to implement Edit/Add/View and Item List button. On clicking item list button, I am displaying Item List. On Item List I am implementing Add/Delelte/View/Edit Item. On Order Page, I am trying to edit only few fields. Could you please suggest any example? Thanks. Srini.

Re: Persisted Object with session scope is getting lost between the pages.
Actually the situation you are describing is not completely clear to me it
seems you might want to do another
getOrder() on form rewinding and merge the additional/showed fields with the
previously persisted fields or add hidden input field components for the
remaining fields but your case is not completely clear to me.

Yes is exactly the same, I quoted 4.1 documentation just because I'm

Re: Persisted Object with session scope is getting lost between the pages.
Hi Martino,
Thanks for the reply. I am using Tapestry 4.0.2. Is ASO
exist in 4.1+?
Thanks.

Re: Persisted Object with session scope is getting lost between the pages.
properties persisted on a page (being client or session persisted) are
persisted just for that page (it's called "persistent PAGE properties").
Just to give you an idea the key of the session attribute named used to
store the property contains the page name . It's intended to be so.
Usually if you want to implement a shopping cart you'd have to use
Application Stato Objects, ASO, see documentation about ASO at
http://tapestry.apache.org/tapestry4.1/usersguide/state.html
basically you just create whatever object you want to persist (e.g. your
shopping cart) , configure it as an ASO using
tapestry.state.ApplicationObjects and then you can easily inject it
with an annotation in whatever page you need it.

Re: Injecting services into application scope ASO
I think what you need is an initialize-method. setConfig cannot be called before the Manager constructor. See http://hivemind.apache.org/hivemind1/hivemind/BuilderFactory.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Injecting services into application scope ASO
Half way there...
Using Hiveutils I managed to write this, but in the Manager ASO
constructor the config is null. The setter for the config is never
called. The Manager is instantiated by a Border component when method
ping() is called. I can use spring provided config in Border component
just fine. What did I miss?
### hivemodule.xml ###
and
### Manager.java ###
public class Manager implements StateObjectFactory {
// Commons Configuration
private Configuration config;
/**
* Manager is an application scope ASO (Application State Object). This
* class is instantiated lazily - when first page injects it.
*/
public Manager() {
logger.info("config: " + config); // <<<<<< THIS IS NULL
String address = config.getString("person.address");
}
public Object createStateObject() {
return this;
}
public String ping() {
return "pong";
}
public Configuration getConfig() {
return config;
}
public void setConfig(Configuration config) { // <<<<<<< never
gets called
logger.info("SETTING CONFIG: " + config);
this.config = config;
}
}
### applicationContext.xml ###
class="org.springmodules.commons.configuration.CommonsConfigurationFactoryBean">
class="org.apache.commons.configuration.XMLConfiguration">
value="classpath:posting-config.xml" />
class="org.apache.commons.configuration.reloading.FileChangedReloadingStrategy"/>
factory-method="getConfiguration"/>
### Border.java ###
public abstract class Border extends BaseComponent {
@InjectState("manager")
abstract public Manager getManager();
@InjectObject("spring:configuration")
public abstract Configuration getConfig();
public void finishLoad()
{
logger.info("person.address: " +
getConfig().getString("person.address")); // correctly print the value
logger.info("manager.ping:" + getManager().ping()); // invokes Manager
}

Re: RE: Re: how to retrieve an Application State Object (ASO) with an application scope from the ServletContext ?
Thanks Ben,
That's what I did and it works great !
Best regards,

2007/1/4, Ben Dotte <[EMAIL PROTECTED]>:
Crap.. I forgot about that dependency on the web request. That never
made sense to me for the case of application-scope ASOs.
In any case, here is a wild idea. If you can capture and hold onto the
Hivemind-created instance of the ASO, you could then give out access to
it through a static getter, similar to a regular old singleton.
To do this you would need to wire up the ASO through a
StateObjectFactory.
So in hivemodule.xml:
In MyAppObjectFactory you can instantiate the object you want to use as
an ASO:
public class MyAppObjectFactory implements StateObjectFactory
{
public Object createStateObject()
{
return new MyApplicationObject();
}
}
Then in MyApplicationObject you could store the instance that gets
created:
public class MyApplicationObject
{
private static MyApplicationObject instance;
public MyApplicationObject()
{
instance = this;
}
public static MyApplicationObject getInstance()
{
return instance;
}
}
Then in your ServletContextListener you can just call
MyApplicationObject.getInstance().
Not the prettiest solution but I believe this would work.

Re: how to retrieve an Application State Object (ASO) with an application scope from the ServletContext ?
I have used the following piece of code to retrieved
an
application ASO in a
HttpSessionListener.sessionCreated method.
It might work in ServletContextListener as well.
// context is the servlet context
Registry registry = (Registry) context
.getAttribute(ApplicationServlet.REGISTRY_KEY_PREFIX_PUBLIC
+ "(the name of
ApplicationServlet given in
web.xml");
ApplicationStateManager manager =
(ApplicationStateManager)
registry.getService("tapestry.state.ApplicationStateManager",
ApplicationStateManager.class);
MyApplicationObject myASO =
(MyApplicationObject)manager.get("myApplicationObject");

Re: how to retrieve an Application State Object (ASO) with an application scope from the ServletContext ?
Hi,
how about using an InjectState annotation:
@InjectState("MyApplicationObject")
public abstract MyApplicationObject getMyApplicationObject();
Maybe this works.
