[T4.1] Two beginner questions (Pageconfig / AJAX)

[Michael Wölm <mi...@net-m.de>]

Hi guys,

after a simple basic test application, I decided to use Tapestry now for 
a real-used office application.
I have one small and one general bigger question, hoping you can help me.

The first question is about configurating directory informations for 
pages. In the .application-file I can setup where to search for the 
.class files by default. But what is with the pages itself? I can 
declare each page or component seperately and his directory-path, but no 
default.
Especially if I have my pages in /WEB-INF/pages and my components in 
/WEB-INF/comps, is it possible to set these paths as default?

The second question is about AJAX. I have used the AJAX-concept much in 
PHP <-> JS[ with Prototype(/Behaviour)].
The tapestry-dev-page gives information how to change an Insertion-Field 
via AJAX. But if I want to change a complete div-component by link, that 
could especially a seperate tapestry-component (Like Ajax.Update() in 
Prototype.js). Is this possible with tapestry itself or do I need the 
tacos-extension? Is there an example source available how to do this or 
could anybody give me some initial "How-To"-information? Example: If a 
user chooses in selection-field account mmustermann, the 
tapestry-component accountdata should reload with all informations of 
mmustermann.

Thanks + Regards,
Michael Wölm

For the directory stuff I think people like to plug in their own
SpecificationResolver implementations (I think there are many in the
wiki) - but I've been wanting to add at least two additional
parameters to the .application file similar to the package classes for
where to find stuff under WEB-INF.

Right now (4.1.2 or later) it will also look for templates using
various component class + package names if it has to.  ie:

com.company.components.CustomComponent

would be (in the worst case) searched for under:

/WEB-INF/CustomComponent.html
/WEB-INF/components/CustomComponent.html
/WEB-INF/components/company/CusomComponent.html

I'm not sure if this has been done for pages yet though... (guess I
should do that)

As for ajax stuff - you can find a lot of information by reading up here:

http://tapestry.apache.org/tapestry4.1/ajax/index.html

For a prototype specific example see:

http://svn.apache.org/viewvc/tapestry/tapestry4/trunk/tapestry-framework/src/java/org/apache/tapestry/scriptaculous/
