Re: GAE problem

[ken keller]

primefaces & richfaces teams seem to dismiss myfaces. Maybe the myfaces team
should get closer to these teams. Latest icefaces might not work w/ myfaces:

Re: java.io.InvalidObjectException: enum constant attributes does not exist in class javax.faces.component.UIComponent$PropertyKeys

[ken keller]

I've verified that if you set the cipher & MAC keys in web.xml, myfaces
works reliably on gae w/ client-side state saving. I've appended sample
settings.

http://wiki.apache.org/myfaces/Secure_Your_Application
"encryption* must be used in production* environments and disable it could
only be valid on testing/development environments."
myfaces doesn't enforce this.

Even if password field value isn't stored in ViewState or ViewState is
encrypted, password is sent in cleartext and thus vulnerable to MITM. That's
easier than rev-engr ViewState. If a black hat has physical access to the
browser, stealing a cookie is easier than rev-engr ViewState. Am I
over-simplifying?

I disabled encryption (see below), redeployed, & everything works--seemingly
it is much more responsive too.

What's the purpose of the encryption? When I View Source, ViewState field
looks like a long, hex string. Even if it can be reverse-engineered, the
values are likely to be the same ones sent in the http request. These are
vulnerable to MITM attack unless one uses https. Is JSF smart enough to
exclude a password field's value from ViewState?

Today all these URLs are behaving w/ client-side saving. Unfortunately
following deployment or when I haven't used the app in awhile:
* ViewExpiredException is thrown after an action. This is surprising since
I'm using client-side saving.
* Typing into hello-prime.jsf's Autocomplete tab's Autocomplete box hangs.

The reason I'm interested in appengine is it is the only auto-scaling cloud
I'm aware of. When you use AWS or the like, you must choose/manage the
OS/webServer/appServer, scale, & deal w/ data center failover. Having
managed 1,000 servers, I certainly appreciate the simplification which
clouds offer but language-specific clouds like Heroku & appengine yield
greater simplification.

Werner,

Thx for digging into this.

I think you're incorrect about how httpsession works. Here is an article
about gae httpsession:
http://blog.comtaste.com/2010/07/managing_session_data_in_gae_a.html
If you want a consistent behaviour you need to invoke setAttribute again
after having modified the Person object in the session.
http://code.google.com/appengine/docs/java/config/appconfig.html#Enabling_Sessions
Because App Engine stores session data in the *datastore and memcache*, all
values stored in the session must implement the java.io.Serializable
interface.

<http://blog.comtaste.com/2010/07/managing_session_data_in_gae_a.html>Thing
is I was getting the ViewExpiredException even w/ client-side state saving.
(I consider this option a great scalability advantage of jsf. wicket seems
to use httpsession.)

Here's a thoughtful article which recommends jsf2 over wicket because of the
active component libs:
http://www.theserverside.com/discussions/thread.tss?thread_id=60755

Re: java.io.InvalidObjectException: enum constant attributes does not exist in class javax.faces.component.UIComponent$PropertyKeys

[ken keller]

I use both of those.

I've started playing with wicket because Gavin recommends JSF or wicket
(both have component models). wicket doesn't appear to have active component
libs like richfaces, primefaces, icefaces.

I'm surprised that richfaces adores mojarra. The lists
http://java.net/projects/javaserverfaces/lists have low activity. Issues
http://java.net/jira/browse/JAVASERVERFACES/ seem to get resolved.

I can only dream of a framework:
* Reliable on gae.
* Several component lib developers conforming to an open look&feel std like
nimbus.
* Client-side validation first to avoid server load & bandwidth for silly
mistakes like not filling in a required field.

Re: myfaces popularity

[ken keller]

I don't see how CDI helps. I tried 3 ways:

X denotes the value of the ID.

1) Pass id as view param using h:link:

  

and bind to pseudo-property named idToLoad in edit_thing.xhtml:

  


2) Pass id as view param using h:commandLink:

  

Action method named edit() gets id from FacesContext:
FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("id");
If that isn't inconvenient, what is? :)

3) Pass id as EL param using h:commandLink:


myfaces complains:
java.lang.NoSuchMethodError:
javax.el.ELResolver.invoke(Ljavax/el/ELContext;Ljava/lang/Object;Ljava/lang/Object;[Ljava/lang/Class;[Ljava/lang/Object;)Ljava/lang/Object;
My action method is:
public String edit(String id) { ... }
My web.xml has:

  com.sun.faces.expressionFactory
  com.sun.el.ExpressionFactoryImpl


  org.apache.myfaces.EXPRESSION_FACTORY
  com.sun.el.ExpressionFactoryImpl

My pom.xml has:

   javax.el
   el-api
   2.2
   
   
   org.glassfish.web
   el-impl
   2.2
   
I don't know why this fails.

What's the best style?

Re: myfaces popularity

[ken keller]

My last startup is www.collectrium.com. We use AWS/py/django. This was my
first non-Java app & I missed strong typing. django's template language is
verbose & there's not much of a widget library. So I'm back to Java. AWS
avoids setting up a data center (as co-founder of IGN.com, I don't miss
managing 1,000 servers) but one still must manage the OS & scaling. So I'm
trying appengine.

jsf's attractions are validation, data binding, component model, component
libraries. Too bad it doesn't include safe HTML (ala
http://code.google.com/webtoolkit/doc/latest/ReleaseNotes.html#SafeHtml) but
it should be easy to wrap text components. Too bad the component library
suppliers won't rally around a standard look-&-feel so one could mix
components.

I like gwt but it doesn't have validation & SEO is too hard. I might use gwt
for editing functionality & a lightweight template language (which doesn't
require a servlet container or mock for unit testing) like freemarker for
browsing functionality.

My current startup is a productivity tool in the cloud. I hope it will be
used by many people of course.

I'm using IntelliJ & appengine 1.3.8. From my web.xml:

 
com.sun.faces.expressionFactory
com.sun.el.ExpressionFactoryImpl
  

>From my pom.xml:

  
   javax.el
   el-api
   2.2
   
   
   org.glassfish.web
   el-impl
   2.2
   

When I run the app, the log shows:

INFO: Either you haven't specified the ExpressionFactory implementation, or
an error occured while instantiating the implementation you've specified.
However, attempting to load a known implementation.

The app works but I wonder why.

I'm having trouble w/ primefaces too.

Finally, what's the correct way to implement an editor action? The managed
bean needs to be initialized before rendering it. So instead of invoking the
no-arg constructor, I want something like:
Foo(id)
to be invoked.

Re: myfaces popularity

[ken keller]

1Mpvs/day on which URL?

mojarra looks inactive:
http://java.net/projects/mojarra/lists
The richfaces team seems to prefer mojarra to myfaces. Given the effort
being devoted to richfaces & primefaces atop jsf2, one would think there
would be much more activity on the lists.

I've posted twice over the last few months about
javax.faces.application.ViewExpiredException
thrown on appengine but nobody replied.

http://www.irian.at/myfaces_support
costs $5,300/yr for basic support--$10,600 for advanced. My startup can't
afford this--especially without trying it first--perhaps a paygo option.

I haven't studied the source code to see if there's unit testing.

As compelling as jsf2 is, I'm scared to bet my startup on it.

myfaces popularity

[ken keller]

This mailing list isn't very active. Most of the messages seem to be about
component libs like Trinidad.

Is myfaces popular?

Wouldn't a searchable group be more convenient than a mailing list?

Re: java.io.InvalidObjectException: enum constant attributes does not exist in class javax.faces.component.UIComponent$PropertyKeys

[ken keller]

Yesterday evening I noticed java.io.InvalidObjectException stopped being
thrown. I don't know why but I hope it is related to switching from eclipse
to intellij & not due to gae. (I also learned facelets is built into jsf2 so
a separate jar isn't required.)

I have two new problems which only happen on live gae--not dev gae:

1) I'm testing jsf-basics.zip on
http://www.coreservlets.com/JSF-Tutorial/jsf2/code/.
* open bank-lookup.jsf
* fill in form
* click [Show Current Balance]
* the correct jsf page is displayed
* click chrome's Back
* javax.faces.application.ViewExpiredException is thrown (whether using
client or server state saving):

This doesn't happen if I submit the form with errors, fix them, & click
[Show Current Balance] button:
* open bank-lookup.jsf
* click [Show Current Balance] button
* validation errors are shown (post back)
* correct errors
* click [Show Current Balance] button
* click Back button

2) A simple use of  doesn't update:

I'm a JSF2/myfaces rookie. I have it working w/ Eclipse Helios & gae Eclipse

the log entry is appended to this message. It appears to be a session

inputHtml

[Ken McArthur]

Hi,

Has anyone successfully used Tomahawk  inputHtml with MyFaces
implementation 1.2.5, Tomahawk 12-1.1.9, and Facelets 1.1.15?

When I try something simple like:

   
...
   


When I put some data in the inputHtml box and click commandButton:
   valueChangeListener never gets called
   converter gets called with empty string
   pageContentDO.value setter method never gets called

This code worked fine with earlier release of MyFaces and Tomahawk so
I'm wondering when it went bad and how far back I have to go to get
inputHtml working again.  Maybe I'm attempting to use bad combination
of MyFaces and Tomahawk.  What is latest release combination of
MyFaces and Tomahawk is anyone seeing inputHtml work?

Thanks for any ideas you may have,
Ken

Martin,

Yea, I originally thought it must be tomahawk but then thought otherwise
because 1.1.6 worked fine with myfaces 1.1.5.  Anyway, new issue is
https://issues.apache.org/jira/browse/TOMAHAWK-1192

Thanks,
Ken

Martin,

That's very cool you found the problem.  I could not find myfaces project on
jira.codehaus.org.  Where do I need to go to open an issue?

Thanks,

inputHtml

[Ken McArthur]

Attempting to upgrade from myfaces 1.1.5 to 1.2.2 and all works great except
for inputHtml.

Using myfaces 1.2.2, tomahawk 1.1.6, facelets 1.1.13.

Get the following exception in the rendering facelets phases:

Caused by: java.lang.ClassCastException: java.lang.Class
at 
org.apache.myfaces.util.AbstractAttributeMap.put(AbstractAttributeMap.java:35)
at 
org.apache.myfaces.custom.inputHtml.InputHtmlRenderer.setThisPageAlreadyRenderedAnInputHtml(InputHtmlRenderer.java:107)
at 
org.apache.myfaces.custom.inputHtml.InputHtmlRenderer.encodeEnd(InputHtmlRenderer.java:93)
at 
javax.faces.component.UIComponentBase.encodeEnd(UIComponentBase.java:556)

Any ideas?

Thanks,
Ken

Re: javax.faces.ViewState contents?

[Ken McArthur]

Mario,

ViewStateDumper is awesome!  I get a large number of "#null?"s in output but
everything else is as expected.  In my situation bottleneck is bandwidth;
especially since ViewState is sent back to server and upload speeds are most
always much slower than download speeds.  Compressed ViewState by adding the
following to web.xml:

  
org.apache.myfaces.COMPRESS_STATE_IN_CLIENT
true
  

This cut ViewState down by about 1/5th.

Thanks again to all.  I think I have good temporary solution but will look
more into server side state saving.

Ken

Re: javax.faces.ViewState contents?

[Ken McArthur]

You mention what I believed to be true.  Since my simple page with a 70kb
ViewState is not requesting saveState for anything, I suspect it must be
something else that's being serialized.  Any ideas on what else it could be?

javax.faces.ViewState contents?

[Ken McArthur]

With client state saving, I was under the impression that only managed beans
in session scope or used in t:saveState would be serialized into the hidden
javax.faces.ViewState variable.  However, my application's creating
ViewStates in pages with very simple forms that are almost 70 kb long!

I'm thinking that if I serialized all managed beans in all scopes + resource
bundle, it might come to about that.

Do you know what specifically is stored in ViewState?  Put in other words,
what is best way to architect application to minimize size of ViewState
while still using client state saving?

Thanks, I appreciate any advice,
Ken

Re: Need to switch image depending on odd or even row in datatable

[Ken Clark]

It turns out that the component change would be too time-consuming (and risky
-- we are two days from code freeze, just trying to clean up a few things.)  

It should have been obvious to me at the beginning how to do this -- I just
added a simple method to the underlying DataModel implementation and then
referenced that.

In the next release we will switch to extending the Tomahawk datatable. 
Thanks for the assistance!

Thanks,
ken

Re: Need to switch image depending on odd or even row in datatable

[Ken Clark]

I think our problem is that we have build our own datatable extension that I
thought was based on the Tomahawk datatable but is actually based on the
MyFaces baseline datatable implementation.

Looking into switching that now...

Thanks for the quick reply.  

I tried that and got this error:
 
javax.servlet.ServletException: Failed to compile JSP
/order/viewOrdersTable.jsp
viewOrdersTable.jsp:17:14: This attribute is not recognized.
 rowIndexVar="_index"

We are using tomahawk 1.1.3 -- is there a version dependency for
rowIndexVar?

Need to switch image depending on odd or even row in datatable

[Ken Clark]

I have a t:datatable which is declared as:



The odd and even styleclasses work fine.  However, I have an image on each
row, and because the background color changes, I need to use 2 different
icons.

How can I go about defining the output such that it uses a different icon
depending on whether the row is odd or even?

Thanks,
ken

Re: [Solved] GraphicImage Question

[Ken McArthur]

Michael,

Here's another option you can try that I've used successfully.  Store images
in a database and create a PhaseListener to retrieve image and output the
content.

making an image object reference in the code running on the server, rather

Thanks, I'll try using my brain next time.

Re: t:inputHtml not working in IE

[Ken McArthur]

I've also experienced this.  It appears Kupu cleans up all the html you
enter here.  In some ways it's good because it makes it xml compliant.
However it also removes  tags. :(
Short answer - no.
If anyone else has a clean workaround for this, I'm all ears.

Need help in getting 'commandButton'

[ken carlino]

I have the following form. The whole form is displayed correctly,
include the input text field values are put out correctly.

But when I click the 'save' button, it does not submit.  It stays at
the same page.

And if I take out the following block(a label and an input text), the
submit works.

  
   
   
   


Can anyone please tell me what the problem? Again, the page is
displayed correctly with the right value. I have checked that
'myAgent' class has getter/setting for 'phone' class and 'phone' class
has getter/setting for 'no'.

Thanks for any help.


Here is my form:







   
   
   
   
   

  
   
   
   

   
   

   
   
   

How to use the inputfileupload component

[ken carlino]

All,


I am trying to use the  in myfaces.

Here is my html file:

   

   
   
   
   

And in my backbean, I have this :
private UploadedFile file;

public UploadedFile geFile() {
return file;
}

public void setFile(UploadedFile file) {
this.file = file;
}

But when I click the submit, the file property is null. I expect it is
popular by myfaces.

Can you please tell me what am i missing?

Thank you.

Common practice of using JSF to develop webapp

[ken carlino]

Hi,

i am going to develop a Java webapp from scratch.
What is the common/recommend practice of using JSF?

What i learn so far is:
* use facelet instead of jsp
* use hibernate for ORM (instead of the whole EJB stuff)
* run it inside servlet container instead of a full blown J2EE server

What are other common/recommend practice?
* Do I need Spring?
* Do I need Shale?
* Do I need Seam?

Problem in marking an InputText to 'readonly' and 'disabled'

[ken carlino]

Hi,

I have page using inputText in myfaces. It works okay. But when I try
to mark the username field to either 'readonly' or 'disabled' equals
to 'true'.

Like this:
  
  
  

the input field of the page in browser is not-changeable (as
expected).  But when i try to do a submit my form, I get this
error message 'This username (null) or e-mail address (null) already
exists. Please try a different username.'


Can you please tell why the username becomes 'null' when I try to
submit? If i remove the 'readonly='true'' the submit works (i.e. the
username is not null).


Thank you for any help.

minor inputHtml oversight

[Ken]

Hi,

Must thank you all for great product.  Through Tomahawk 1.1.3 I've
noticed a minor issue with inputHtml.  Tomahawk logs following
error:

- Unable to find resource resource/kupudrawers/kupublank.html for
component inputHtml.InputHtmlRenderer. Check that this file is
available in the classpath in sub-directory /resource of the
package-directory.

In fact, kupublank.html is in the resource directory.  When I copy file to resource/kupudrawers error message goes away.

What is best way for noncommitter such as myself to fix this problem for everyone?

jscookmenu nesting h:hiddenInput

We are trying to use jscookmenu to add some navigation to our web app...

However, we need to pass some data via an inputHidden tag (for a

available.

Our tests show that the h:inputHidden tag is not generated within the
jscookmenu's form.  

Is there any way to do this?

Try removing a couple of jar files from WEB-INF/lib of the application in webapp.I'm pretty sure one of them is commons-el-1.0.jar. Don't remember the other one but the MyFaces Tomcat configuration help page lists it.

when is form tag required?

[Ken]

Hi,Given commandButton, commandLink, and outputLink all render as html anchors, I only wrapped them with form tags when a form field was required (inputText, selectItem...).  Everything worked fine across multiple browsers in myfaces 
1.1.1.Now with myfaces 1.1.3 and tomahawk 1.1.2, I'm having a difficult time finding consistent behavior.  Does anyone know when the commandButton and commandLink tags require to be in a form (or require a form within it's page) in order to execute its action event?

I have built a very simple JSF web app and am having trouble trying to deploy

I have a simple .jsp with this tag:


The faces-config contains:

session


and the CalcBean class has methods getResult():String and
setResult(String):void

it all seems like it should work, but I get the error above.

I am using the MyFaces 1.1.2 release (core only) and Weblogic 8.1sp4.

It is a bit frustrating that the error that actually occurs does not show up
in the stack trace -- only its getMessage() value
"javax/servlet/jsp/el/FunctionMapper" which doesn't tell me much of
anything.

Any ideas?

problem getting 1.1.1 from svn

Re: ApplicationImpl Configuration Problem

[Ken Weiner]

Thanks for the reply, Martin.

I'm not really sure if I understand whether or not they are MyFaces
specific or not.  Some seem to be "standard" as they have
javax.faces in their ID's and come from a file called
standard-faces.config.xml.

These are the converter ID's for which FacesConfigurator tries to set the Converter configuration instance:

javax.faces.convert.BooleanConverter
javax.faces.convert.NumberConverter
javax.faces.convert.BigIntegerConverter
javax.faces.convert.DoubleConverter
org.lmb.faces.converter.bool.BooleanConverter
javax.faces.convert.FloatConverter
javax.faces.convert.IntegerConverter
javax.faces.convert.ByteConverter
org.apache.myfaces.convert.StringArrayConverter
org.apache.myfaces.custom.fileupload.UploadedFileConverter
javax.faces.convert.BigDecimalConverter
javax.faces.convert.ShortConverter
javax.faces.convert.CharacterConverter
javax.faces.convert.LongConverter
javax.faces.convert.DateTimeConverter
Since my Application is not an ApplicationImpl, then FacesConfigurator
doesn't inject the configuration into ApplicationImpl and then when
MyApplication delegates to ApplicationImpl, ApplicationImpl throws a
NullPointerException in this code because it has a registered converter
but not the corresponding configuration:

private Converter internalCreateConverter(Class targetClass) {

   
Converter converter = (Converter) converterClass.newInstance();

   
org.apache.myfaces.config.impl.digester.elements.Converter
converterConfig =
   
(org.apache.myfaces.config.impl.digester.elements.Converter)
   
_converterClassNameToConfigurationMap.get(converterClass.getName());

   
Iterator it = converterConfig.getProperties(); <-- a NPE is thrown
here because converterConfig is null

}

The result is this stack trace.  My application is "SpringApplication":

Caused by: javax.faces.FacesException: Could not instantiate converter: class javax.faces.convert.IntegerConverter
    at org.apache.myfaces.application.ApplicationImpl.internalCreateConverter(ApplicationImpl.java:556)

ApplicationImpl Configuration Problem

[Ken Weiner]

I have a custom ApplicationFactory that wraps the original
ApplicationFactory so that it can produce a custom Application that
wraps the original Application.  It is configured via
faces-config.xml:


    custom.MyApplicationFactory


As a result, the FacesConfigurator class is not able to properly
configure all the standard Converters (for Integer, Long, etc) because
it relies on setting instances of
org.apache.myfaces.config.impl.digester.elements.Converter on the
ApplicationImpl (and my Application is not an instance of
ApplicationImpl):

if(application instanceof ApplicationImpl)
{
    for (Iterator it = _dispenser.getConverterConfigurationByClassName(); it.hasNext();)
    {
    String converterClassName = (String) it.next();

    ((ApplicationImpl) application).addConverterConfiguration(converterClassName,
    _dispenser.getConverterConfiguration(converterClassName));
    }
}

Therefore this inner block of code is passed over in my
environment.  Is there any way that MyFaces can be changed so that
ApplicationImpl does not need to know about
org.apache.myfaces.config.impl.digester.elements.Converter
internally?  It would be nice if the FacesConfigurator could
configure any Application without relying on it being an
ApplicationImpl.

Assuming user logged in with an id, you could save this value as a

Apply Request value Phase:

Apply Request Values phase, or at the end of Invoke Application

events) that normally happens during Process Validations phase to occur during 
Apply Request Values phase instead.
If I have  or commandButton that has
immediate=true, the all their action listeners will be executed in
Apply Request Value phase before updating model. IF immediate=false,
all the action listeners will be executed after ACTION(Invoke

Re: JSF + Spring + Hibernate

[Ken Weiner]

The issue I was getting at was that knowing that your app has this lazy
loading capability, you may make different design decisions on what
methods go into your domain objects and what your domain object graph
looks like. I prefer to design the domain object graphs, keeping in
mind that the DAO layer would be responsible for completely loading the
graphs.  So if there are many Employees for a Company and you
don't always want to load the Employees when you load a Company, then I
probably wouldn't put a getEmployees() method on the Company
class.  I guess you could argue that it is okay to add the
getEmployees() method and document it so that sometimes it returns null
and sometimes it doesn't, but that seems undesireable to me.  I'd
rather leave off the method and add an extra method to a DAO that can
fetch the employees for a Company whenever I need them.

Re: JSF + Spring + Hibernate

[Ken Weiner]

I have a question about designing a webapp to use a DAO layer, lazily
loaded objects, Hibernate, and the OpenSessionInView technique.

Doesn't this strategy make it very difficult to reimplement the DAO
layer sometime in the future?  If you switched a DAO
implementation from Hibernate to let's say, Spring JDBC, then how would
all the lazy loading work?  There would be no equivalent
OpenSessionInView technique for Spring JDBC.  For this reason, I
have been shying away from designing my domain objects such that the
rest of the app expects them to lazily load data.

So, instead of a Company class having a getEmployees() method, I would
choose, instead, to have a CompanyDao.getEmployees(Company company)
method that must be called at the point my webapp needs all the
Employees for a Company.

Have any of you had the same concerns?  Or am I missing how a
webapp that relies on lazy-loaded object graphs can change DAO
implementations easily?

Re: h:commandLink with f:param not working with expired session.

[Ken]

FYI, Looks like there's a bug in JSF.  See
http://forum.java.sun.com/thread.jspa?threadID=549675&tstart=0

Hope this helps anyone else who may be running into this problem.

JSF has  and , but nothing I've
seen to convert Booleans to custom values.  Has something like
 already been written by anyone?  I have just
written one and would be willing to contribute it to MyFaces if there
is interest.

It is used like this:

Re: How to call a method in the backing bean from a JSF page

[Ken Weiner]

I am not sure if this is the best way, but one idea that could work is
to create a PhaseListener that acts after the view is restored.  In
this phase listener, you could check if the view being restored is the
view for which you want to call your backing bean method.  Then, you
could obtain a MessageBinding object for your backing bean expression
and use that to call your method.

Create YourPhaseListener and register it in faces-config.xml:

...

com.yourcompany.YourPhaseListener



public class YourPhaseListener implements PhaseListener {

public void beforePhase(PhaseEvent event) {
// Nothing to do
}

public void afterPhase(PhaseEvent event) {
FacesContext facesContext = event.getFacesContext();
UIViewRoot viewRoot = facesContext.getViewRoot();
String idOfYourPage = ...
if (viewRoot.getId().equals(idOfYourPage)) {
Application application = facesContext.getApplication();
String methodExpression = ...
Class[] params = ...
MethodBinding methodBinding =
application.getMessageBinding(methodExpression, params);
methodBinding.invoke(facesContext, ...);
}

public PhaseId getPhaseId() {
return PhaseId.RESTORE_VIEW;
}

}

Disclaimer: I haven't tried this code so I don't know if it would work
or even compile.

Re: How to call a method in the backing bean from a JSF page

[Ken]

Yes, commandLink and commandButton will render an anchor tag.  If you
don't want to do this you can do work in your properies getter method
when it gets called by outputText value and return an empty string. 
However, I don't believe there is any guarante as to call order. 
Putting your target outputText in the first line of your jsp file
doesn't mean it will get called before other getter methods further
down in the jsp file get called.

Re: How to call a method in the backing bean from a JSF page

[Ken]

Try h:commandLink or h:commandButton.
If your method returns a string that doesn't match any navigation-rule
in your faces-confix.xml then the same page you came from will be
rendered again.

h:commandLink with f:param not working with expired session.

[Ken]

I'm attempting to convert working Sun JSF RI application to MyFaces
containing many h:commandLinks with nested f:param tags.

For some reason most but not all of my commandLinks no longer execute
the action method when my session has expired.  I'm not sure why some
work and others don't anymore with MyFaces.  Can't determine the
difference but behavior is inconsistent even within the same h:form
tag.  Instead, framework goes straight back to the same jsp page for
many of my commandLinks without giving me a chance to do anything in
the action method.

I've tried various configurations of the type attribute (button,
submit).  Tried commandButton.  Also tried various
org.apache.myfaces.DETECT_JAVASCRIPT and
org.apache.myfaces.ALLOW_JAVASCRIPT parameter settings in web.xml.

What am I missing?  Anyone have any ideas why my action methods aren't
getting called after my session has expired?

Thanks,
Ken

Re: Questions on required="true" attribute

[Ken Weiner]

Thanks so much for pointing out that messages tag.  I was just about
to write something similar because I didn't know about it.  Is it
listed somewhere on the MyFaces website?  I don't see it here:
http://myfaces.apache.org/tomahawk/overview.html

Regarding your comment on it being specific to MyFaces:  Isn't it only
specific to the MyFaces extensions?  In other words, couldn't I use it
with the RI as long as I included the myfaces-extensions-1.0.9.jar and
referenced the taglib?

It seems like you could get the best of both worlds with an interface
and an abstract class that implements it.  Since this has been
well-vetted by the EG, I'll accept the reasons it was done without an
interface.

So, it sounds like the JSF implementation *does* get to choose whether
or not javax.faces.render.Renderer is an abstract class or in
interface since an "instanceof Renderer" check could be done for an
instance of either.  Am I understanding correctly?

Re: Why not reuse jsf-api.jar from Sun?

[Ken Weiner]

Martin, yes, I will file this as an issue in Jira and reference this
email thread.

Craig, thank you so much for your response.  I now understand the
relationship between a java spec and the physical API source code much
better.  You brought up an interesting point about JSF being different
in that there is more executable code than in other frameworks.  What
was the reason that classes like javax.faces.render.Renderer were
defined as abstract classes rather than interfaces?  In Section 8.2,
the spec refers to what an "instance" of Renderer should do.  Does the
word "instance" imply a class rather than interface or is it up to the
implementation?

Re: Why not reuse jsf-api.jar from Sun?

[Ken Weiner]

Thanks for the replies.  Do other specs from JCP behave this way?  I
don't remember ever seeing another situation where there are multiple
versions of the same exact (same fully-qualified name) class.

Here is an example of how my component would break if I switched
implementations:

Let's say I am coding a component that has children components.  My
component extends javax.faces.render.Renderer.  If I am using the RI,
I may be tempted to accept (not override) the implementation of
Renderer.encodeChildren() which simply iterates thought the children
and renders them as follows:

public void encodeChildren(FacesContext context, UIComponent component)
throws IOException {
if (context == null || component == null) {
throw new NullPointerException();
}
Iterator kids = component.getChildren().iterator();
while (kids.hasNext()) {
UIComponent kid = (UIComponent) kids.next();
kid.encodeBegin(context);
if (kid.getRendersChildren()) {
kid.encodeChildren(context);
}
kid.encodeEnd(context);
}
}

Now if I switch to MyFaces, none of my children would render because
the MyFaces version of javax.faces.render.Renderer.encodeChildren()
does not render the children.  It looks like this:

public void encodeChildren(FacesContext context,  UIComponent component)
throws IOException
{
if (context == null) throw new NullPointerException("context");
if (component == null) throw new NullPointerException("component");
}

So if I understand things correctly, my component would essentially
break because none of its children would render with MyFaces.  Does
that make sense?

I realize I could override the encodeChildren() method to be safe, but
don't you agree that it would be easy for someone to fall into a trap?
 Maybe, in this case, one of the implementations is not adhering to
the spec.

Why not reuse jsf-api.jar from Sun?

[Ken Weiner]

I am confused about the nature of the javax.faces sources that are
included in the MyFaces jar file.  They appear to have been written as
part of the MyFaces project.  Sun includes alternative versions of the
javax.faces classes in its RI distribution, placing those classes in a
seperate jar file: jsf-api.jar.  Why doesn't MyFaces reuse the
jsf-api.jar from Sun?  Shouldn't there only be one version of the API
classes, with Sun RI, MyFaces, and other supplying only the "impl" of
the API?

The way it is now, if I were to write my own, let's say
MyAbstractRenderer, and I extend javax.faces.render.Renderer, then my
components could break if I switch between the RI and MyFaces.  I hope
someone can help me understand the nature of the JSF spec, API
classes, and various implementations.  Thanks.
