Tapestry 4.1.2 LinkSubmit issue
Hi all, I know that LinkSubmit implementation was changed in the last snapshot of 4.1.2. Now javascript method call, which submit the form pass from href attribute to onclick attribute of the link. I have custom javascript method, which i want to call as a handler of onclick event before form submit. How can I add my method as a handler of onclick event? -- View this message in context: http://www.nabble.com/Tapestry-4.1.2-LinkSubmit-issue-tf4047483.html#a11496848 Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T5 IoC: How to invoke a decorator method after the service method invoked
Thanks for the reply Howard. What I'm trying to achieve here is to
create a declarative transaction. So before the service method is
invoked, I want to begin a transaction, and commit when the service
method is finished.
I'm going to try out the explanation you have given me. But I think
I'm still far off from creating an interceptor with javassist.
Another question: Is the SampleInterceptor.foo invoked from the
decorator method?
PS: I think you need to add a reference regarding on creating custom
decorator here just to prevent others asking the same question like I
did. :-D

The interceptor has the same interface as the service.
The decorator is passed the service, which it can then provide to the
interceptor. It's called the "delegate" (because it may not be the
service, it may be another interceptor, but that's actually not
relevant).
So, the interceptor has the same methods as the service, and a
do-nothing interceptor would just re-invoke each method on the
service.
Example:
public interface Sample() {
String foo(String bar);
}
A hand-assembled interceptor would look like:
public class SampleInterceptor {
private final Sample _delegate;
public SampleInterceptor(Sample delegate) { _delegate = delegate; }
public String foo(String bar) {
// Logic before delegate invocation here.
String result = _delegate.foo(bar);
// Logic after delegate invocation here.
return result;
}
}
Of course, we don't use hand-written interceptors often, we instead
brew up the interceptors on the fly inside decorator methods, using
JDK dynamic proxies, or Javassist (ClassFactory and friends).
Notice the two comments; you see that you can add logic before
delegating, even to the point of changing method parameters before
re-invoking. In theory you could even invoke a different method on
delegate, or not invoke the method, or invoke a method on some other
object.
Likewise, you can have logic after invoking the method. You could
even but a try ... finally arround the call to _delegate and trap
exceptions.

(T4.1.2) Ajax enabled Table componet in T.1.2.
Hi Group, Forgive me if the answer is obvious, but I have searched using Google and have not found anything helpful. I am using Tapestry 4.1.2 on my first Tapestry project and I would like to use the table component but with Ajax updating. Ideally I would like to say something like async="true" and updateComponents="myTable" with the table components like with all the other tapestry components. Can someone point me in the right direction or let me know that this is not possible. Thanks, Jon - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: T4.1.2 Survey: Is Selenium working for you?
Thanks, Jun, but are you using client-side validation AND Selenium TestRunner (as opposed to Selenium RC or Selenium IDE)?

Re: [T5] Optional constraint in Validator?
The fact that optional parameters worked in the past was unintentional. However it seems like a good idea, I'm just trying to think of the best way to implement it. I'd rather not add another method to the Validator interface, if possible ... in fact, I'm thinking of simplifying it (putting more of the information gathered from the interface into a contribution to the service) ... go ahead, an an issue, but bear in mind that the API will likely change a bit.

Re: T5 IoC: How to invoke a decorator method after the service method invoked
The decorator creates the interceptor.
The interceptor has the same interface as the service.
The decorator is passed the service, which it can then provide to the

So, the interceptor has the same methods as the service, and a
do-nothing interceptor would just re-invoke each method on the
service.
Example:
public interface Sample() {
String foo(String bar);
}
A hand-assembled interceptor would look like:
public class SampleInterceptor {
private final Sample _delegate;
public SampleInterceptor(Sample delegate) { _delegate = delegate; }
public String foo(String bar) {
// Logic before delegate invocation here.
String result = _delegate.foo(bar);
// Logic after delegate invocation here.
return result;
}
}

Hi all,
Sorry for the long subject :-D.
Ok straight to the point. I'm currently building a decorator for a
Service. But the problem I'm facing is, the method inside the
decorator is only invoked before the service method is invoked. What I
want is the decorator method to be invoked before and after the
service method is invoked. How do I get this? I saw the logging
decorator method is invoked before and after, but I just still can not
get the idea. Perhaps there should be a reference on building custom
decorator? :-D

Re: T5 - Changing Locale
Your code worked for me, except I replaced ThreadLocale by PersistentLocale
@Inject
@Service("PersistentLocale")
private PersistentLocale persistentLocaleService;
then it works using e.g.
persistentLocaleService.set(new Locale("fr"));
