Re: t:form cannot be created?

[Howard Lewis Ship]

This is quite odd; I'd check your compiler settings ... Tapestry 5.2
is a bit sensitive about JDK version, sometimes 1.6 throws it for a
loop (that's the Javassist bytecode library, which has been sidelined
in Tapestry 5.3).

Re: Specifying several event constants for the @OnEvent annotation?

[Howard Lewis Ship]

-1

Thiago had the right solution.  Further, the second event
("fromMyAjaxEvent") will occur after the "activate" event itself
(assuming that the Ajax-request originating component is on the same
page).

It is very much an exception to the rule to have multiple events
handled by the same method. It is occasionally useful to have a single
method handle events from multiple component ids (by exploding the
"from" portion of the method name).

Look around line 90 in your AppModule
(com.packtpub.services.AppModule$1.service(AppModule.java:90)) and see, if
you can get a clue. If not, please post your AppModule's code and we'll see,
if we can find an error.

You could implement one method that is called by your two event handlers.
E.g.

@OnEvent(EventConstants.ACTIVATE)
final void callEventHandlerFromActivate() {
 this.doTheWork();
}

@OnEvent("yourAjaxEvent")
final void callEventHandlerFromMyAjaxEvent() {
 this.doTheWork();
}

private final void doTheWork() {
...
}

Hi

I also had this error message some time back when I created a non

Re: Netbeans and Tapestry integration

[Alex Kotchnev]

The live reloading doesn't depend on anything eclipse specific - it's a
tapestry feature. As long as your compiled classes end up in a container
that supports it (e.g. in the past, I've had problems w/ live reloading and
Tomcat), you should be OK.

The "Compile on Save" feature in NetBeans is something that you definitely
want to enable in your project properties - this is what compiles the
classes and would put them where the servlet container needs them (make sure
that you don't do "Deploy on Save" as that completely removes the need for
tapestry live reloading as it uses integration w/ the servlet container) .

Are you using native NetBeans projects or are you working w/ NetBeans and
Maven projects (btw, both should work, but probably slightly differently)  ?


Cheers,

Alex K

I am on holidays, and trying to use some Tapestry awesome features, as the 
inyection.

But I do not understand some issues, and cannot find the answer in the wiki or 
somewhere, to the info is not enough clear for me, sorry.

This is very simple. In the Java part of a page I want to inject the DAO, so I 
use this code:

@Inject
private IAplicacionesDAO appDAO;

To have this code running I need to add the service implementation via 
AppModule and bind:

public static void bind(ServiceBinder binder)
 {
binder.bind(IAplicacionesDAO.class,AplicacionesDAO.class);

Two questions:

a) if I add a constructor to the first class, I have an error:
Class com.earroyoron.pages.VerAplicaciones was not transformed for use as a 
component; this can happen if it is an interface, or was not in a package 
subject to component transformation
and in the documentation I read the constructor was needed! But without it 
works and with it I have an error….
A constructor should not be used in a Page or Component class. Tapestry 
does a lot of work behind the scenes when deployed to transform these 
classes you write so they function nicely. Read up on the page 
lifecycle: http://tapestry.apache.org/page-life-cycle.html


I assume there is some initialization you would like to do on your page 
when it is rendered and displayed (which you may have thought belonged 
in a constructor), for this you would implement one of the render 
lifecycle methods.  http://tapestry.apache.org/component-rendering.html


For example

@BeginRender
public void loadUser(){
userId = 1;
appDAO.loadUser(userId);
}


b) Cannot Tapestry find the service without the bind? The infection in the DAO 
to use Hibernate does not need to say nothing to Tapestry, it works without any 
extra configuration in module.

You will need to do the binding so it can auto-bind your service for 
you. You could alternately write a build method to build the service 
yourself, but that would be more work and I'm assuming is not what you 
wanted. http://tapestry.apache.org/defining-tapestry-ioc-services.html

Netbeans and Tapestry integration

[earroyoron]

First, I am sorry this email was sent to dev@tapestry list too, it was my fault!

The message was:

Hi all!

I am starting to use Tapestry,… impressive framework!

I am developing an application, using eclipse, and I had some problems with 
DerbyDB. I prefer Netbeans to do some things, and I could resolve my "derby 
affair" with the NetBeansIDE.

But now I was still using NB and, I, … is my fault or the live reloading

Does the live reloading uses some eclipse "thing"?

T5.3: customize validation messages

[stephanos2k]

I'm running T5.3 and want to overwrite the existing validation messages. I
created my own file 'MyValidationMessages.properties' and tried to
contribute it.

But I only found references to the deprecated
'contributeComponentMessagesSource', or hints to
'contributeComponentMessagesSource' - but I don't quite understand how to
apply it to my case.

What's the correct way?

Cheers,
Stephan

If the handler methods for two different events are same, then you probably
need only a single event.

BTW: Firing activate event might cause unexpected behavior as activate is
already "reserved" by Tapestry.

Re: Can't call EventLink when ajax popup another page.

[Bo Gao]

Thanks very much.

Finally I found my problem. I have the following code on my page
Object onActivate(){
if(someSessionScopeObject==null){
return Index.class;
}
}

And on my Index page
Object onActivate(){
sessionManager.set(theSessionScopeObject.class, null);
}

And when I load the component using ajax, Tapestry call Index.onActive, clear 
the sessionScopeObject, 
Then if i click an eventlink on the first page, mypage.onActive is called. And 
I am redirected to Index page.

It's all my mistake.

Specifying several event constants for the @OnEvent annotation?

Hello,
I need for a method to be called upon several events (e.g. ACTIVATE and
ACTION).
I tried the following:

*@OnEvent(value = {EventConstants.ACTIVATE, EventConstants.ACTION})

jobPostings = service.loadJobPostings();
}
*
and it does not work/compile unfortunately. Am I missing something?
Can anyone please help?

[eray]

Hello everyone,

I am very new to Tapestry, so it can be that this is a silly question, but I
cannot find a way out of this situation. I am trying to apply the examples
in the Tapestry 5 book of A. Kolesnikov. I copy the error message and my

Thank you in advance.

Re: onActivate doubt

[David Canteros]

Hi, thank you both for the answers!

I know the problem of passing user&pass via url, but for the time being I
can't change it.  All pages ( except Login ) are protected by
@RequiresAuthentication annotation of tapestry-security framework thus they
are locked if you are not logged. Login page appear because I have defined
the following security symbols in the Module:

*configuration.add(SecuritySymbols.LOGIN_URL, "/login");
configuration.add(SecuritySymbols.DEFAULTSIGNINPAGE, "/login");
configuration.add(SecuritySymbols.SUCCESS_URL, "/Index");
configuration.add(SecuritySymbols.UNAUTHORIZED_URL,
"/Unauthorized");*

My doubt was the onActivate() method behavior. Why was the page loaded and
wasn't onActivate launched? Do you think the way that the page was invoked (
implicitly) causes the behavior?. I will try nillehammer's suggestion, and
I'll have a look at jumpstart as well.

Thank you again!

David
