Hi everyone.


 


I just have put an example how Ajax4jsf works 
with Facelets on the https://ajax4jsf.dev.java.net/  (at the bottom of the page). The live demo is here: http://livedemo.exadel.com/a4j-numberguess-facelets/


 




 


We have not too much for interaction the 
javascript code on the page yet (We just do not want to force end developers to 
use javascript on the pages more than enough). Only the reference to the event 
on the target component. Such as <a4j:support event="onmouseup"> . 
Internally, for the component development, we use javascript, namely 
prototype.js's  AJAX object and its API. (We use prototype.js instead 
of sexy Dojo. At least it is version 1.4, but not 0.3 ). So, from this 
point of view, Jacob is right. It is a higher level concept.


 


The primary ideas of Ajax4jsf are enhancing the 
existing JSF components adding AJAX capability to them and establishing and 
standardizing the process to create new JSF components with built-in 
AJAX support and other kind of richness. From this point of view 
<a4j:support> is an example of the first idea, but the 
<a4j:commandButton> is a prove ;for the second one. Also, everything 
should be fully integrated into the JSF environment including livecycle and 
event system&nbsp;(reusing the same validatiors, converters and renderers in 
AJAX mode the same way as in regular mode).


Actually, it were the ideas of Alexander Smirnov 
when he introduced his framework about one year ago ( http://smirnov.org.ru/en/ajax-jsf.html 
). We have added to it the resource manager (including generation resources 
on-the-fly with setting right content type) and skinning (predefined set of 
params to define look-n-feel). On the way to contribute to open 
source&nbsp;- Component Development Kit(CDK) and auto testing 
environment.


 


We like the idea of integrating existing 
JS widgets into JSF environment. The only question is how. Personally, I do 
not accept&nbsp;EBA ( http://developer.ebusiness-apps.com:8888/EbaJsfComboBox/ 
) way when the widget send the open URL to the server. This is what I 
call hack-my-bean-approach. Like this one:





At least, the Mabon ( https://mabon.dev.java.net/ ) secure 
mechanism is required here, but not only. JSF has events, such as value 
changes event. Why one more is need here. Converters, validators: as soon as it 
is an input controls, how the JSF works here.


 


JMaki ; ( https://ajax.dev.java.net/ &nbsp;) . Cool approach to involve the existing 
widgets. I have to look closely how the 
server-side intergation works in JMaki to understand my position about this 
approach.


 


JSON, sent as AJAX response: if it is for replacing 
the part of the page, I did not see the point why we have to duplicate the 
existing renderers. Ok, if we enhance the existing JS widget that works with 
JSON originally, it makes sense.


 


Idea about Ajax4faces foundation is 
great.&nbsp;Ajax4jsf can donate the first part of the project name already ). 
Seriously, it is a right time to concentrate our efforts. We have several 
solutions that are designed and developed independently, but pretty close 
to each other conceptly. So, it is a good sign that we are on the right way to 
establish the optimal approach&nbsp;for&nbsp;JSF-AJAX integration.

We are working on it now actually.

There was also 
discussion with Exadel (ajax4jsf) and IceFaces folks about collaborating on a 
solution.  Ajax4jsf is the closest to the solution we presented at J1, but 
it's too high level and we need an API which does integrate with other 
client-side coding, including JS widgets from Dojo or MyFaces.&nbsp; So work is 
being done to setup this foundation such that ajax4faces, etc can extend higher 
level concepts on top of it to make development even easier.

Hey Jacob- 

When are you, Ed and Adam 
going to release the Ajax-JSF framework (see message below)?&nbsp; Based on your 
javaone demo, I'm very interested.  Ed mentioned it was going to be a part 
of the jsf-extensions project on dev.java.net, but I don't see anything. 


I think that your approach or the ajax4jsf project that the exadel 
people have put together are clearly the leading contenders for simple JSF-Ajax 
integration.

For those that are interested:
