T5 included javascript libraries
Hi,
T5 adds several js libraries to the body, e.g. prototype.js,
scriptaculous.js and others.
Are they all required, or is there a possibility to affect
which libs are added to the body?
Thx && cheers,
Martin

Ouuups, sorry, my fault! There was still another form in our layout
template that didn't have the clientValidation="false" - now I've set
this and js libs are added to the body - really cool!
Thanx for your help,
cheers,

RE: T5 included javascript libraries

Thanx for this explanation, Adam!
I just set clientValidation to false for my form, however, the js files
are added to body. Is it somehow possible to tell T5 not to add
these libraries (or scriptaculous.js) to the body?
Otherwise, as a very ugly hack, it should be possible to replace the
js files by empty ones, as long as we're using none of them...
What do I have to add to the configuration in
contributeApplicationDefaults to specify the
"js/empty/scriptaculous.js"? Or where do I find documentation concerning
this question?
Thanx a lot,
cheers,
Martin

>From what I can tell only the Form component uses prototype and
scriptaculous when the clientValidation parameter is set to true (which
is the default). The tapestry.js that is added as part of the Form
component uses some of the element and event helper methods from
prototype and some of the effects from scriptaculous.
The way the scriptaculous library works is that when the base
scriptaculous.js is included in a page all of the various files for the
library (builder, controls, dragdrop, etc) are dynamically added as
additional script tags within the body of the HTML, no matter if the
individual components are used or not. This has the negative side
effect of making the rendered page code ugly (and difficult to
troubleshoot in firebug) as well as creating 5 additional server
requests.
I would suggest replacing the default prototype and scriptaculous
libraries with a minified (and compressed) version:
http://groups.google.com/group/prototype-core/browse_thread/thread/40e58
15f5bc5fba9
http://protoculous.wikeo.be/
Currently using one of these solutions that combines prototype and
scriptaculous is not possible with the Form component since it wants to
add a separate file for both prototype and scriptaculous. However
adding compressed versions for each works.

Are these js files used at all? I ask as they increase loading time
and I'd like to remove them if they're not used...
However, wait 5 days and I'll ask how to start with ajax in T5 ;)

You have some control, via contributions to the ApplicationDefaults
service configuration, over where the files come from, so you can use
a different version of prototype & scriptaculous than the ones
provided with Tapestry. However, we have yet to take a crack at an
abstraction layer that would allow you to replace p&s with some other
similar library, such as Dojo.
