how/where is tapestry.js included?
Hi all,
I recently figured out that 'tapestry.js', 'prototype.js' etc is only
included when you have at least one tapestry component within a tml.
I can't find where this logic takes place however.
I need to make use of prototype and tapestry js on a page which does not
have any tapesry components and want to figure out the simplest way of
including them.
Thanks, Paul.

Got it.
So as soon as you @Import a library, the stack comes down too.
Thanks.

It looks like Howard's example is like approach 1 here http://tapestry.apache.org/javascript.html
The @Import annotation when used with the element "library" as shown in his response is for js libraries. Same as "stack".
For use with a stylesheet, use the element "stylesheet"
http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/annotations/Import.html
Good question & answer for a Friday :)

Basically, when your code invokes most methods of JavaScriptSupport
(or, in older versions of Tapestry, RenderSupport) that triggers the
inclusion of the "core" JavaScriptStack. "core" is "tapestry.js" plus
supporting libraries such as prototype.js. This intent is that, if
you are not using JavaScript on a page, you don't force the browser to
load all that JavaScript.
So, for example, if you page has some JavaScript associated with it,
package that into a companion JavaScript file (I usually name it the
same as the Java class, but with a different extension), thus:
@Import("library=NiftyPage.js")
public class NiftyPage { ...
Now Tapestry's core stack, including prototype & scriptaculous, is
loaded as well as your JavaScript.
This is better than inline <script> elements, from a bunch of
performance and maintainability points of view.

I would look at the source code of the simplest tapestry component to see how it does it.

The inclusion by components is a side-effect. You can trigger the auto-inclusion without a component by using code that depends on the stack. In particular, if you call JavaScriptSupport.addInitializerCall, JavaScriptSupport.addScript, if you import a library (via annotation or directly via JavaScriptSupport.importJavaScriptLibrary), or you import another stack (by annotation of via JavaScriptSupport.importStack), tapestry will import the full tapestry stack (tapestry.js, prototype.js, etc.) for you.
