JSF and ajax using phaselistener approach
Hi,
Can anyone give me links to any resources/examples on Ajax with JSF using
the PhaseListener approach. I found it on the J2EE Blueprints but they work
only with Java EE 5. I am using myfaces 1.1.4 (J2EE 1.4). Does this approach
work with that too? Please give me some links/resources.
Any help is appreciated.
Thanks a lot.
Regards,
Aneesha

Right,
shale remote and mabon are designed to invoke backingbean methods. the
pattern is similar.
regarding ajax4jsf/dynaFaces, there is also PPR stuff in Tomahawk
Sandbox (dojo based) and Trinidad (iframe based)
one more note on mabon, it provides a client-api based on dojo.

Many of the JSF components in the BluePrints Catalog library[1] are built
using Shale Remoting, using it for two different purposes:
* Retrieving static CSS and JS files that are embedded in the
JAR file containing the component classes
* Mapping to an asynchronous callback handler by translating
a portion of the URL to a method binding expression
You can grab the sources for the components to see how this was done.
Further questions about using Shale Remoting to build your own components
would best occur on the Shale user mailing list[2].

Any idea how to use shale to write a custom ajax-enabled component? It seems
that it can work only with plain html, according to the introduction on
their page. So to use shale and make it ajax-enabled, I need to make my data
table manually with <table><tr><td> tags instead of using tomahawk
datatable?

You don't have to wait for a future version to get some relief. In JSF 1.2,
the UIComponent.invokeOnComponent() method was added, specifically to make
AJAX integration easier, especially when you want to operate on part of the
component tree instead of all of it. A lot of the current pain is due to
the fact that this wasn't there in 1.0/1.1.

Re: JSF and ajax using phaselistener approach

Oh I agree with you Jeff. Sometimes I wish there was something as simple as
doing <h:datatable ajaxenable=true> or writing JSF component tags from
javascript in a jsf page instead of html or something. It is really painful.
I'd much rather choose ajax without JSF over this, if I could. :-(

Ah, very interesting. Certainly seems like a cleaner alternative for
components that don't want to cause any side effects.

I just now read a bunch of articles/slides on this, mostly by Jacob
Hookom and Ed Burns. That does indeed sound neat - especially for
components like dataTable.
Even though we still have some pain using this stuff today, people are
coming up with clever solutions. Seems JSF is evolving in terms of
supporting stuff like AJAX, and hopefully the future promises even more
innovations.
Thanks for pointing these out to me guys.

Matthias,
I agree, more components does not make for a better spec. The place for
neat components are libraries such as Tomahawk. The last thing I want in
JSF 2.0 are some funky ajax-ified components, but rather more native
support for ajax across the board. I get the feeling that products like
ajax4jsf would have a lot fewer bugs if the JSF lifecycle provided
better hooks for what they are trying to do.
By the way, I noticed that Jacob refers to you as "the great Matthias."
Either you've been leading legions of soldiers to conquer neighboring
countries, or you're developing quite the reputation in the JSF world.
...then again, it could be the beer talking. ;)

I expect framework extensions from jsf6 (see [1]) and perhaps an
client side api.
But, please no random-components and no calendar and no xxx-components.
Let's work on the API / Framework, but on *blowing up* the sepc with
new components.

Re: JSF and ajax using phaselistener approach
Posted by Jeff Bischoff <jb...@klkurz.com>.
Sounds painful.
I really hope that a future version of the JSF spec integrates AJAX more
directly into the framework. For now, I am seeing more ajax components
showing up in Tomahawk/Sandbox and that at least is something.

RE: JSF and ajax using phaselistener approach
Posted by Michael Heinen <mh...@recommind.com>.
I had also the problem, that the datascroller did not work anymore:
I solved this with by using always the same ids for the links and not
the pagenr as id suffix.
Here are some tips:
DataScroller:
I created my own DataScroller with corresponding Tag and Renderer. All
those classes extend the corresponding HtmlDataScrollers from MyFaces.
It is important that encodeChildren does nothing and you have to call
scroller.getChildren().clear() in encodeEnd().
Otherwise links could be rendered two times.
I could fix the problem with the not working links by creating dummy
links for all pages in renderPaginator
Something like this:
//create dummy links until maxPages is reached. These links should
not be encoded!
//Otherwise the links are not executed after AJAX refreshs and data
model updates that result in more pages.
if (idCounter<maxPages)
{
for (;idCounter<maxPages;idCounter++)
{
if (scroller.getAjaxified())
{
// create an AJAX Link
this.getAjaxLink(facesContext, scroller, idCounter,
idCounter);
}
else
{
this.getLink(facesContext, scroller, idCounter, idCounter);
}
}
}
Note that these dummy links should not be encoded !
Then I patched the getLink methods:
It is important that the links keep the same ids after ajax refreshs
independent of the pagenr!!! Otherwise they are not executed.
MyFaces used the pagenr as id suffix for the links and this does not
work!
You have to use something like a linknr which starts always at 1 and
runs til maxPaginatorPages.
DataTable
- use a value binding for the first attribute of the datatable and
manage this property in your backing bean. e.g. set it to 0 if you sort
the table
- overwrite or extend
org.apache.myfaces.component.html.ext.HtmlDataTable
public void setFirst(int first)
{
ValueBinding vb = getValueBinding("first");
if (vb != null)
{
//vb.setValue(getFacesContext(), first);
return;
}
else
if (_preservedDataModel != null)
{
//Also change the currently restored DataModel attribute
_preservedDataModel.setFirst(first);
}
super.setFirst(first);
}
The above two points are important to get the right page visible in the
datatable for scrolling or sorting after datamodel updates.
Hope this helps,
Michael

Hi Michael,
Here is the description of my specific problem:
I got the datatable, sortheaders and datascroller working with Tomahawk.
Then I was trying to ajaxify the table loading on the basis of a drop
down. The table loads with ajax perfectly however, the datascroller and

tomahawk not work with Ajax4jsf?
Can anyone help me look into how to make this work?

In addition to the other references people have given, you might want to
look at the Remoting feature in Shale[1]. It includes a built-in phase
listener that tries to do all the hard stuff so you don't have to, and
an extensible Processor architecture so you can plug in your own
processing logic.
One important factor is that Shale Remoting assumes you do *not* need
access to the JSF component tree for the original page (thus eliminating
the overhead of saving and restoring it), or even that the client be a
JSF page at all. If you need that, you might want to look at
Ajax4JSF[2] or Dynamic Faces[3]. But, if you just need an easy way to
hook incoming requests to back end business logic, and like the ability
to use JSF's managed beans and expression evaluation capabilities,
Remoting might be useful to you.
(Incidentally, Shale Remoting is what many of the Blueprints AJAX
components are using under the covers to acccess static resources, or
connect to server side event handlers.)

You wanna look here
mabon.dev.java.net
that pretty much explains, why PhaseListeners can cause fun.
(no chance to "order" their execution; what happens, when other PL do
*wrong* stuff...)
