1.2 spec is not yet released; it's at "proposed finaldraft", and has been for many months.Indeed, no one can actually "release" a "General Availability" implementation of a JCP spec that is not final yet.  But that doesn't stop you from working on such an implementation, on the assumption that it will eventually go final (since JSF 
1.2 is part of JavaEE 5, I think that's a pretty good bet :-).I doubt very much if MyFaces will manage to release a 
1.2-compatibleversion in the next six months. Sun have made JSF 1.2 dependent on a newversion of the EL "_expression_ language" library, and on a new version ofJSP. Until those exist MyFaces can't even begin to implement much of JSF
1.2.And I'm not aware of any progress on implementing the next JSP versionby Apache Tomcat or other such projects. As far as I am aware, Sun isthe only one with an implementation of this near completion. That would,
in fact, prevent the official release of the spec for manyorganisations; it's common to require at least 2 successfulimplementations of a spec before it is considered ready for release. I'mnot sure that Sun works by those rules though.
MyFaces is intending to add some JSF1.2 type features into the current1.1-compatible release. Encrypted client-side sessions are already donefor example.In addition, there is still a lot of work to be done to stabilise the
current 1.1-compatible release. I personally would like to see effortput into this before moving on to the next spec version.One option for the MyFaces community to consider, with regards to JSF 
1.2, is to utilize some portions of the JSF 1.2 reference implementation, which (unlike the JSF 1.1 RI) is under the CDDL license.  The implementation of the new EL APIs seems like an obvious candidate for this.  In turn, though, this would require pushing on Apache to accept dependencies on CDDL-licensed code -- from my conversation with insiders, there seems to be no conceptual problem with CDDL's terms; it's caught up in a larger strategic initiative on dealing with non-Apache-licensed software.  If the MyFaces community wants to, this would be an obvious case where it would benefit the world.  I'd happily go advocate that scenario, if the MyFaces community felt that this was the right direction to go.
It isn't by any means required that such a dependency last forever -- if it makes sense to create your own implementation, that's perfectly fine.  Consider using the RI code a short term strategy to get a release out the door more quickly than would otherwise be possible.  If the code works, and does everything you need, then no harm in relying on it.  If it doesn't, replace it -- that's what open source is about.
But I need to reiterate a comment above, because it is not obvious to me that the MyFaces development community has figured out all the implications yet:* JSF 1.2 will be (when it is released -- trust me, that is not a long time away :-) a *required*
  API to be supported by any Java EE 5 server.* That means, any app server vendor who is planning on implementing Java EE 5 is going  to need to make a JSF technology choice sooner, rather than later.
* At the moment, there is only one viable JSF 1.2 implementation that I am aware of.  In the absence of any other choice, this will become the default selection.* Specific use cases -- if/when Geronimo and JBoss decide to implement Java EE 5,
  they are going to require a JSF 1.2 implementation.* Is the MyFaces community interested in being an option for app server vendors?  If so,  it's time to move quickly.  Once a particular app server chooses a particular implementation
  of a particular dependency, it's generally pretty difficult to affect that choice later.* If MyFaces is satisfied being a JSF 1.1 implementation, for non-JavaEE5 environments,  then none of the above matters.  ((In my personal opinion, that would be a poor choice,

The biggest problem I can see with making the default value for this

be backed by data loaded from an ORM tool such as Hibernate.  In this 
case, it would be very easy to run into LazyInitializationExceptions or 
equivalent.  Also, as pointed out, if the data is loaded from the

this, because in my experience when a user sees a new page load they 
expect the data to be the latest.  Making them have to hit an additional 
refresh button would just confuse them.

On a bit of a different note, something I've run into with DataTables 
that bugs me is the way JSF handles the Master-Detail pattern.  Using 
the traditional way of finding the object the user selected with the 
DataModel.getRowData() method is error-prone if another user adds an 
object that would appear in the table before the one the user is trying 
to drill-down on.  The user could wind up with an off-by-one error,

In addition, there is still a lot of work to be done to stabilise the

The SVN current version of AddResource allows non-faces classes to serve
resources from jars. However this functionality is NOT available in the
1.1.1 release.

There are some steps needed to enable non-faces code to use AddResource;
I haven't done this myself so I'm not entirely sure but I think it
involves writing your own (trivial) ResourceHandler class.

There is a hidden field in each form that is used to store the id of the
command component that caused the form to be submitted.

Each command component (commandLink, commandButton, etc) has javascript
attached to it which sets this hidden field to the command component's
id before performing the submit.

In the case of a commandLink in a table, the javascript rendered for
each row will set this hidden field to a slightly different value (ie
indicating the row).

After a submit occurs, the table does:
for each row: 
  set row index
  call decode for each child component

Therefore on each row the commandLink component looks for its id in the
hidden field - but this is only found when table rowIndex matches the
one that the user clicked on. When this occurs, the commandLink
component queues an event for later processing; this is intercepted by
the UIData component which wraps it in a custom event class that knows
about the current row.

When the event is executed, the custom event class ensures the UIData's
rowIndex is set to the appropriate row for the event before the
ActionListeners attached to the commandLink component are run. Result:
the code run by the ActionListeners can look at the parent table, and
see its rowIndex and rowData objects are set to the appropriate values
for the row containing the link that was clicked on.

All this *does work*; I use it - and with sorting enabled too.

Perhaps you're correctly sorting at the render phase, but are returning
the data in a different order during the "decode" phase?

Simon

link inside extendedDataTable

Can anyone explain to me how a link inside extendedDataTable whose
action is bound to a rowVar bean method gets executed?  I have a case
where I invoke a method binding on the rowVar bean in the table.  When
I click on the link the method is executed but not on the correct
row/bean in the table.  My problem began where I started sorting the
list return to data in the getData method.  I guess my sorting of the
list is not being propogated to the list data model.  The rows appear
in the order that is expected.  It is just invoking the link on the
correct bean in the unwind process that is not working.  I am using
myfaces 1.1.1.  Other things to note, the link isImmediate is true (I
also tried false) and FacesContext.renderResponse is called first in
the invoked method.  The invoked method also returns null because I
want to stay on the same view.

You might consider Struts Shale's remoting support for myfaces (http://struts.apache.org/struts-shale/shale-remoting/apidocs/index.html).  It allows an AJAX call into the JSF life cycle invoking an action bound method on a managed bean.  It assumes a URL convention where the managed bean name and method are specified as folders within the URL.
 
Consider the following example where “remoting$business”is the managed bean name and “cityAndStateForZip” is the method.: 
sendRequest("http://localhost:8080/struts-shale-usecases/" +    "dynamic/remoting$business/cityAndStateForZip.faces" +    ?zip=" + escape(zip),     processZipCodeSelection);

JSF 1.2 support/plans

[Balunas, Jay]

Hello all,

I have been lurking for some time, and have been investigating JSF for a new 
project at my company.  Please forgive me is this has come up already - I did 
search through several pages of archives and could not find a reference to 1.2 
support roadmaps

Because this will be a new project starting in about a month, and first release 
around end of summer (August -September) I have been investigating both the 
current 1.1.1 version of myFaces, and looking into what 1.2 JSF provides.  We 
are planning on using Ajax and from what research I have done JSF 1.2 has some 
hooks for making Ajax requests less of a hack into the life cycle.

We are also investigating Suns implementation, but I would prefer to stick with 
myFaces as the support and community seems stronger.

Thanks in advance,
Jay

Werner, are you sure it was an issue with jsf-spring and not with spring?
Remember when we talked about the jenia4faces/jsf-spring/jetty issue
with resolving references?  It turned out to an error in Spring, not
jsf-spring.

There's not a lot going on in the jsf-spring code.

Re: abt how to locate jsp file and the syntax of myfaces-config.xml

[Mike Kienenberger]

It's my understanding that the inaccessiblity of files placed in
WEB-INF is part of the servlet specification.

Thus, this is true if you're using Spring, JSF, Struts, WebWorks,
Click, WebObjects, or anything else.

What it does is makes it illegal to directly request any resource with
a URL that contains /WEB-INF/ in the path.

So, if you want to use

http://localhost/mywebapp/index.jsp
http://localhost/mywebapp/xxx.jsp

then your default *.jsp-processing servlet needs to either have a
method in the code to fetch the hidden page, or you need to move your
jsp files out of WEB-INF.

Note that I'm no expert in this area, so some of this information is
possibly incorrect.

RE: How to make Client Side JS validation working on form submission?

[Jeffrey Porter]

To start with look at…

 

http://www.exadel.com/tutorial/jsf/jsftags-guide.html

 

& the section…

 

Enter address:

 

 

required="true" will make sure the person enters some data in
to that field.

Also add in the line…

 

 id="messageList" styleClass="error" summaryFormat="{0} in {1}" />

 

That will print out the error messages.

 

Hope that gets you started.

RE: abt how to locate jsp file and the syntax of myfaces-config.xml

[wch zll]

Hi,

In Spring it says put jsp files in WEB-INF can protect
your files from direct access, but Spring has its own
lib, so in spring.xml file has

 
org.springframework.web.servlet.view.JstlView

/WEB-INF/jsp/
.jsp


So here it has "prefix" and "suffix", so the yyy.jsp
inside WEB-INF/jsp/ can still be access while
http://localhost/mywebapp/yyy.jsp

So i am just wondering in myFaces, is there any
configuration also this kind of functionality.



Thanks!

RE: Urgent: Collapsible Panel with data table not workingIllegalStateException: Client-id : _id3ToggleCollapsed

[Saurabh Rasinghaney]

Hi Simon,

Our requirement is not flexible enough to change the interface - though
I can use a different component but the functionality should be same.

Can I add other components such as Input and check box etc, to a tree
table component? Or can you suggest any component which can provide
single level drill down with component addition at parent and child
levels.

Also, can I use Oracle ADF with Apache MyFaces? I wanted to understand
if it will be feasible and wise to do that. I was looking at it and
thought we might need to do two different Faces Servlet configurations
and configure extns such that ".jsf" for Apache Myfaces and ".faces" for
Oracle ADF.

Thanks a lot for your help.

Best Regards,


Saurabh Raisinghaney

Hi Saurabh,

You can use subversion to look at the history of the CollapsiblePanel
component/tag/renderer classes and see what patches have been applied
since the last release. You'll need to figure out which bits are
suitable for applying to the 1.1.1 release and which are not.

I expect the irian site is running a nightly build, not an official
release.

Using c:foreach around JSF components is definitely not supported; it's
not at all surprising that problems have occurred.

However if I were you, I'd redesign the interface to avoid collapsible
panels entirely. It's the simplest solution!

Cheers,

Simon

I forgot about that! In that case a simpler pattern would work nicely:

preserveDataModel="true" always,

and

public DataModel getDataModel() {
return new LocalDataModel(.);
}

This will still cut out the database access during the Restore-View phase,
and would be sufficient for almost all cases.

For those who are really efficient conscious - my original pattern can still
be used (maybe with 'refresh' button for user to refresh the data). I don't
think there will be any significant differences between these two patterns
in real cases.

I think components that do not save its state are 'wrong'. JSF handles this
by calling the backing bean, while ASP.NET simply left them blank - but both
are wrong in their own way. 

In ASP.NET once a component is specified to participate in viewState then it
behaves like my first pattern. But there is no equivalent to the second
pattern. In ASP.NET you simply have to do refresh a dataTable manually.

I am really happy to find a frame of comparison between these two
frameworks. JSF does has its advantages - but it has been hard work trying
to figure out how to use it properly though.

Why is AddResource not usable outside myFaces?

[Juergen Melzer]

Hi,

I want to use the mechanism like myFaces to load javascript resources.
I use the class org.apache.myfaces.component.html.util.AddResource.
But when I want to use it I found in 1.1.1:
"For security reasons, only components member of the 
org.apache.myfaces.custom are allowed to add ressources"

In 1.1.x:
"expected a myfaces custom component class in package 
org.apache.myfaces.custom"


Is there is a reason to do this?

Juergen

RE: dataScroller

[Miller, John]

Not that I am aware of, however it would
be a simple change to add, I would recommend asking the dev community to add
this functionality. As a workaround you could add multiple scroller components
and only render the one you want passed on your page, this is sloppy but would
work: for example (sorry about the incomplete code I am at work and don’t
have time to give you actual working examples)

Is there an easy way to further control
the datascroller functionality – specifically, not display the
‘previous’ or ‘first’ control if on the first page of
data (and also not display the ‘next’ or ‘last’ control
if on the last page of data)?

DataScroller by default will not render if
there is only one page of data, however the facets will, you can turn this off
by simply adding the following attribute to your datascroller

 

renderFacetsIfSinglePage="false"

Another possible is that you set the
rendered attribute of the datascroller  to false or true at the point
where you get your list for the datatable in the backing bean.





e.g something like that in your backing
bean:





 





rowList is the result you will display on
the datatable. In my example a datascroller will only be displayed if the list
contains more than 5 items.





 





 if (rowList.size() > 5) {
dbAdminDto.setShowDatascroller(true);
   }
   else {
dbAdminDto.setShowDatascroller(false);
   }





 





 





in the JSP:











    rendered="#{dbAdminDto.showDatascroller}"





...





/>





 





I hope it's clear, what I mean...

Isn't this only a problem if the dataModel is directly backed by the
database, so that the database is accessed on each call of getDataModel()?

Hello

I have try to pass to myFaces 1.0.8 to 1.1.1 and with ADF faces ea19, 
component works but i have got a problem.
In final html page in navigator i have javascript error, because render 
component call javascript function, that is no insert in page, like 
getscrolling().


I build my configuration with your web site help and with simple 
application, but i don't see where i have wrong, some boby can tell me 
what is it wrong with my config , is it the listener in tld that is no 
call ??



thanks,

RE: How can I redirect from a servlet to a JSF page (that is backed by a bean)?

[Jeffrey Porter]

Hello all again.

I've messed around with the Tobago code for 5 hours now and have
achieved 1/2 what I want.

I can redirect to a JSF page & populate the backing bean, but...

I now have this problem with the redirect code...

The problem I have is when a commandButton on the JSF page is clicked it
makes another call to NonFacesRequestServlet servlet, rather than making
a call back into the servlet from MyFaces.

I'm sure this problem is to do with what I should be returning in the

  String getFromViewId() method. 

And what I should have in my  section of
faces-config.xml.


Does anyone have any ideas?

Thank you!
Jeff.

RE: An optimised pattern for using t:dataTable - please verify.

[Jesse Alexander \(KBSA 21\)]

in this direction. thanks for the hint.

Then come the other requirements as well:
- ability to render one record on more than one row
- dynamic col-spans according to different data-objects
- automatic datascroller
- sort and filter headers (multiple sort criterias)

Our users (read the developers here) are VERY creative...

But I still hope we find the cash to finance our inhous
infrastructure project... to make such components ;-)

Re: MyFaces + Shale + Facelets

[Alexandre Poitras]

Yes I agree with you but it would be great to be able to use the clean
EL syntax of JSF managed beans in the xml files. To refer aother bean
property in spring, you need to declare it using a special bean wich
is very verbose.

The mixing approach you talking about is because we confuse two
concepts here. Declarative programming and configuration. For
instance, declaring a bean stateful has nothing to do with the
configuration because if you change it to stateless your code need
some changes. A datasource url is a configuration and need to be put
in a centralized configuration. This changes has no impact on your
code. I think the confusion comes from the fact that a configuration
is declarative by nature.

In you're first email you said want to access..

In your second message, you said you want it to be protected.

So if you want yyy.jsp to be protected, then why are you trying to get
direct access to it?

I presume was you would want to use yyy.jsp as an include later on,
rather than direct access to it. For example...

<%@ include file="/WEB-INF/jsp/include.jsp" %>


I could be completely wrong about this. I've not used the spring frame

Why do you have the yyy.jsp under WEB-INF ?

Hi,

I have a standard web application, it's arranged in

  --some css files

the problem now is how I can launch the page by
http://localhost/mywebapp/index.jsp
http://localhost/mywebapp/xxx.jsp

but i can't launch http://localhost/mywebapp/yyy.jsp,
error is page not found. I know this error would occur
since yyy.jsp is in WEB-INF/jsp/,
but if I want launch this yyy.jsp, then how should I
configure web.xml or myfaces-config.xml? So can set

RE: An optimised pattern for using t:dataTable - please verify.

[Jesse Alexander \(KBSA 21\)]

I am milling around since quite some time on the subject of 
datatables.

In our app we have the case that hibernates fetches a few megabytes of
data, which will then be saved in the state and the hibernate-objects 
remain referenced -> no gc...

My current thoughts are about a datamodel that does not keep all data
but just a part of the data active and requests the missing data when
paging is requested...

But I still have the unfinished business of the optional validation for 
JSF 1.1 (without facelets)

if we find some developers that want to start on such a better table-
component... (without committer-rights) we can share the code on a
temporary base on the js-comp.sf.net project

regards
Alexander

Oh - and also that the user will never see any changes to the database
made concurrently by other users. That may be desirable, or maybe not.
Of course if it is desirable, then a read before each render has to be
done. 

However as you point out in (2), the model used for rendering really
does need to be preserved until the start of the next render phase for
consistency - and that saves one database read too.

I would love to see t:dataTable (and maybe h:dataTable) avoid fetching
the datamodel during validation when there are no input components in
the table; that would make a nice project for someone wanting to get
involved in MyFaces coding!

Cheers,

Simon

Re: MYFACES-27 JSCOOKMENU

[Bruno Aranda]

I've reopened the issue and fixed this in the SVN. Now, there is a new
attribute immediate for the jsCookMenu (note that defaults to false to
be consistent with UICommand, maybe some users may have to put
immediate="true" in their menus). I haven't tested this because there
is some problem now with the generation of the examples due to the
maven reorg, but will do as soon as I can. Thanks Igor,

Re: An optimised pattern for using t:dataTable - please verify.

[Simon Kitching]

Hi Yee,

Yes, I agree with this. I think you've put it all very nicely.

The only concern is that point (6) can be hard to get right.

NB: The default behaviour (no preserveDataModel) is flawed because it
doesn't get (2) right for datasets that may be changed by something
other than the viewing user.

Cheers,

Simon

An optimised pattern for using t:dataTable - please verify.

[Yee CN]

Hi, Below are some thoughts that came to me after months of trying to understand the dataTable. Please verify that it is accurate enough for Wiki.  1)    By definition the Restore-View phase should restores whatever that was being rendered in the Render-Response phase of the last request.2)    A t:dataTable that does not persists its data in viewState would have to call the backing bean to obtain the table data again during the Restore-View phase. If the data obtained is different from what was being rendered previously, it could lead to inconsistencies.3)    That explains tomahawk preserveDataModel="true" extension to dataTable component – to make ensure that (1) is upheld.4)    Given the above understanding, consider the code scriplets below.5)    preserveDataModel should be set to true base on the reasons given above. It will restores the backing bean dataModel using the setter method (*1), during the Restore-View phase.6)    If the backing bean action changes the database, then the dataModel should be invalidated (*2) so that it will be regenerated with the updated data.7)    However if the bean action is known to not doing any update to the database, the dataModel should be left alone.8)    This pattern will avoid the most hated and hotly discussed problems of JSF hitting the database twice on every request. This pattern is actually highly optimal – in that it will only hit the database again when you explicitly invalidate the dataModel. The price to pay is relatively small – which is saving the page of data in the viewState. --- The JSF --

  

 --- The Backing Bean -- public class myBean extends serializable { (*2) public String changeDbAction() {    // an action that changes the database. Invalidate the dataModel here    // so that the it will be regenerated during the Render-Response phase    this.dataModel = null;     …    return SOME_NAVIGATION_RESULT;} (*3) public String doesNotChangeDbAction() {    // action that does not change the database. So leaves the dataModel alone      // and the Render-Response phase will not result in hitting the database.    …    Return SOME_NAVIGATION_RESULT;}

 

(*1) public setDataModel(DataModel d) {    // t:dataTable will call this method to restore the table data    this.dataModel = d;} public DataModel getDataModel() {    // if the dataModel is being invalidated then regenerates it again    if (dataModel == null) {        dataModel = new LocalDataModel(…);    }    return dataModel;}

 

}

    

 

Best regards,

Yee

RE: How can I redirect from a servlet to a JSF page (that isbacked by a bean)?

[Jeffrey Porter]

Great page Mike! It was very useful.

I have another question leading on from it though.

I now have the servlet redirecting to the page I want, it populates the
bean on for the page. BUT (there's always a but)...

The commandButton's on the page now call in to servlet, instead of
calling the action that I'd expect.


Example of commandButton 



Does anyone have any ideas?
(I'll add notes on this to the wiki when I find the reason/solution)

Thanks
Jeff.

I personally love the EJB3 @Bean @inject @outject paradigm
very clean and tight.

I think things like bean definitions at least should have the optional
option of annotations, I do not thing blocking the xml way is good at
all, in many situations you need a centralized configuration of things.
But in many you do not need it, a mixed approach in this area might be
the best way to go.

It should, yes to my knowledge jsf-spring (although it did not work for
me in my last project) should allow the calling from jsf beans within
spring and vice versa thus you can scope beans over jsf.

Things will become easier however with spring 2.0 then you simply define
all beans in spring and have faces-config doing the rest.

(the xml syntax according to the spring devs, also will be cleaned up
and tighter, I have not looked into it yet though)


Have in mind that jsf-spring works quite well in many situations, but
some situations still are problematic with that lib, I recently (in fact
last night) ran into the situation of not being able to deploy an app on
websphere due to the fact that jsf-spring interfered with the WAS6 class
loader.
But at least if you go the one way route there are other fallback
options. So choose your binding technology with care upfront and do some
minimal testing.
