Tristate property (true/false/null)

[Steph]

I try to handle a tristate property (true/false/null) with a radiogroup :

   
   true
   false
   not defined
   

but the selection of "not defined" set my property to true.
Is there a specific way to handle null values ?

Injection of Spring bean aliases as services in Tapestry pages

[Steph]

I can easily inject a service A defined in Spring like that :
   
in my tap pages :
   @Inject
   @Service("A")
   private MyObject a;
That works fine.

But if i declare in Spring an alias B on my bean A :
   
when i try to inject my bean B in my tap pages :
   @Inject
   @Service("B")
   private MyObject b;
Tapestry can't find this service  and i get the following exception :
org.apache.tapestry.internal.services.TransformationException: Error 
obtaining injected value for field 
com.cariboonetworks.ads.pages.MyPage.b: Service id 'B' is not defined by 
any module.


Any idea ??

T5 : Form with synchronous Submit and asynchronous components

[Steph]

How can a form in Tap 5.0.11 include asynchronous components (select, 
checkbox, ...) which update the form itself and a synchronous submit 
which redirects on another page in its onSuccess event ?

T5 : Dependant dropdown boxes

[Steph]

Has anyone already tried to implement dependant dropdown boxes with the 
Ajax features of Tapestry 5.0.11 ?
I would like to implement a component to get a user address (country, 
zipcode, city) and i would like to present the user the cities according 
to the zipcode and the country just filled.


Any ideas ?

Re: Event bubbling

[Steph]

Each time a piece of information is rendered several times in a page.
Say for example in a contact list. Each contact is displayed by a 
component including 'remove', 'update', 'details' links.
I already know what you will say ... "move the handler from the page to 
the component" ;-)


But, in the point of view of application architecture, i'm not sure that 
it is a good thing to split in different components the functions which 
manage the same piece of informations.
In the contact list sample, my component won't be able to manage the 
creation of a new contact. So i will end up with the CRUD functions of 
my contact split in the page displaying the contacts and the component 
displaying a contact details.


If i could handle all events in the page, my page would be able to 
encompass all the contact management functions ...

Re: how to access components pages ???

You just have to inject :

   @Inject
   private ComponentResources componentResources;

Then, you access page properties like this :

   componentResources.getPage().get

T5 : How to get a Page in a Dispatcher ?

[Steph]

Hi all,

I have implemented a Dispatcher based on the wiki solution provided by 
Chris Lewis in order to check the authentication of the users on several 
pages of my application.
But instead of check the access rights of a user based on the URL, i 
would like to check it against the Page instance (say on the presence of 
a @Private annotation put on the page).

Has anybody a clue to get the page instance in the dispatcher ?

Thanks in advance.

T5 : declaration of pages and components packages from a library

[Steph]

Hi all,

I need to import in my tap5 project a library which includes tap5 pages
and components.
But when i try to extend a page from the library in my project, i get
the following exception :

java.lang.RuntimeException: Base class com.mylibrary.pages.FramePage
(super class of com.myproject.pages.Start) is not in a controlled
package and is therefore not valid. You should try moving the class to
package com.myproject.base.

Should i declare the 'pages' and 'components' directories of my library
in the tapestry.app-package context of my web.xml ? If yes, what is the
syntax to do such a declaration ?

Thanks in advance.

Re: [T5] 5.0.7 - Help with log4j.properties file

How do you get your logger in your code ?
The injection
@Inject
private Logger log;
is only useable in Tapestry pages, components, ...
It will log nothing in your other classes managed by Spring, Hibernate, ...
Outside of Tapestry, you should use something like the line below to use
slf4j :
private final Logger log = LoggerFactory.getLogger(YourClass.class);
