Instead of using 2 onActivate() methods, you may also make use of
EventContext. It's often less verbose and better to read:

Object onActivate(EventContext eventContext) {
switch (eventContext.getCount()) {
case 0:
return NoContextPage.class;
case 1:

Notice that the custom function is only called _after_ validation

Well, if you want to do a custom JS, u can do a Zone Update of the Form,
then observe Tapestry.ZONE_UPDATED_EVENT, for doing some some custom JS!
But, that happens only after form submission and not before that!

* List _news = _session.createCriteria(RNews.class).list();*

}
}
When i run the actionlink, i get an NullPointer Exception at the bolder line
above (at the _session.createCriteria(RNews.class).list()).. Why does this
happen? Isn't this mean, @Inject is not working, hence the _session is not
initialized??

Your DBConnect object is probably not in one of the tapestry controlled
packages and thus inject doesn't work. You can inject the Session directly
into your page, or turn your DBConnect object into a tapestry service by
adding it to the services package, and changing the Session into a
constructor argument.
You can also declare DBConnect as a Tapestry service. Doing this, you can
@Inject DBConnect and the @Inject annotation inside it will work.
In your AppModule, add this method if you don't have it already:
public static void bind(ServiceBinder binder) {

Re: [newbie] EventListener in Tapestry 5 ?
Well, if you want Mouse and Text field (key press events), use Java Script on the client side, its very useful and efficient. If you're very particular, use DWR to map JS events to a Java Class @ server side, but with in-built ajax support, Tapestry doesn't require it though.

Help with t:loop
Hi, I'm currently trying to create looping structure in one of my pages. The source attribute is an object (an entity). The entity, has a value, which refers to the ID of the other Entity's reference. Its like i've a column - postedBy - this has UID (an Integer) from another entity. My question is, when i use a loop to generate the content. How do i refer to the other entity's other column, using this ID in this entity? - Ashwanth Kumar
Re: Help with t:loop

It is an object that must be an array or an Iterable (Collection, List,

The entity, has a value, which
refers to the ID of the other Entity's reference.
Why doesn't it have a direct reference to the other entity instead of using
its id? This doesn't sound object-oriented to me.

Remember classes don't have columns, they have fields and properties.
Suppose this other entity class has a name property.
Create a method getName() that returns the name and use ${name} to print it
in the generated HTML.

The Zone raises a JS event when is updated. This is explained in the
Zone documentation:
http://tapestry.apache.org/tapestry5/tapestry-core/ref/org/apache/tapestry5/corelib/components/Zone.html
After the client-side content is updated, a client-side event is
fired on the zone's element. The constant Tapestry.ZONE_UPDATED_EVENT
can be used to listen to the event.
You just need to provide a Prototype listener for that event in your page.

Some points: 1) Tapestry is a servlet filter, not a servlet. 2) There isn't a non-threaded version of HttpServletRequest, as it is created for every request received. 3) As far as I know, it's not possible to count the number of concurrent users without using the session, as HTTP is a stateless protocol. You'll need to count open sessions. To do that, you'll need a service to hold the number of open sesions and an HttpSessionListener.

Help with Tapestry i18n
Hey,
People, I've a problem using inbuilt, i18n support of Tapestry (I use
5.0.18). K, When i use persistentLocale and set it to Locale(hi), hi -
Hindi, its not picking up the page, Home_hi.tml or Home_hi.properties.
Instead, it uses any page like, Home.tml or Home_en.tml
Also, the same problem for the Indic lang., like Locale(ta), etc.
Is there any workaround for this?? I want my app, to read from the
Home_hi.tml and Home_ta.tml files while creating the markup.
I tired, removing the en from the Supported Locales, from the AppModule
Class, also.. My Lines are follows:
public static void contributeApplicationDefaults(
MappedConfigurationString, String configuration) {
configuration.add(SymbolConstants.SUPPORTED_LOCALES, ta,hi);
configuration.add(SymbolConstants.PRODUCTION_MODE, false);
}
For, the Home.java, here goes the code:
public class Home {
@Inject
private PersistentLocale persistentLocale;
private String locale;
public Home() {
persistentLocale.set(new Locale(hi)); //
setLocale(persistentLocale.get().getDisplayName()); // This text displays
the Name as Hindi, but renders the Home_en.tml or Home.tml page only
}
/**
* @param locale the locale to set
*/
public void setLocale(String locale) {
this.locale = locale;
}
/**
* @return the locale
*/
public String getLocale() {
return locale;
}
}

Help with i18n in Tapestry 5.0.18
Hey, I'm using Tapestry 5.0.18, and trying to add a localization to my app. I found, that, Tapestry supports Localization for only certain languages, like the static fields, in the Locale class. It works for Japanese, German, French, etc., But, does not support indic languages, like Hindi(hi) or Tamil (ta), etc.. Though i tired giving Index_hi or Index_ta *.properties, and *.tml files, both doesn't work. In both the cases, it searches only for Index_en or Index *.properties, and *.tml files.?? Is this a limitation of Tapestry or am i doing something wrong here? I also added the supported locales constants in the AppModule class, in the contributeApplicationDefaults method.
