RE: Custom renderer for h:outputText - possible?
Could be then that somehow MyFaces does not allow to overwrite the standard renderers. Why is so? Is there a page about it in the JSF spec so I could confirm it's right or not? would have to check the spec... but usually it works also for MyFaces... Maybe you should grab the MyFaces source and analyze it or debug the setup part of the applicaiton start. I'm a mere JSF user and I'd rather avoid delving into the MyFaces sources. I want to understand how jsf works first before doing so. If it's the last resort I'll follow the advice. Often it helps a) to understand the workings of JSF b) accelerate solutions for bugs by analyzing the stuff as a user and maybe even hint at possible solutions regards Alexander

RE: Selenium and badboy on JSF
Forcing ID's is not too expensive, if you start early with it. It's not only tools like Selenium and BadBoy that might need fixed ID's. Also LoadPerformance Tools depend on either name or id-attribute and if those attributes change between test-runs or (even worse) between page-views, then you can imagine that you get high bills from the team preparing and executing the tests... It would be nice though, if some setting would tell the JSF-impls to force ID's on all input- and command-related components. THEN the developer would automatically specify the IDs from the very beginnning. regards Alexander PS: I like Selenium, using JUnit-tests and Selenium-RC From: Yaron Spektor [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 06, 2007 3:06 AM To: MyFaces Discussion Subject: RE: Selenium and badboy on JSF Thanks Shawn and Rafa, I was actually hoping for a simple solution that does not incur code changes. and forcing the ID's may be too expensive.

I will have to profile your application to find out where your CPU bottleneck (if it's a CPU bottleneck) is, or where your network bottleneck is. Because JSF uses value binding which can do lots of things, any badly written/badly used bean can be at cause (like a bean loading 50.000 items for a database at each request). Simple suggestion: when you load a JSF page, go in a console to your solaris station and run a kill -3 JVMpid, this will dump to the jvm's stdout a stacktrace of all running threads. From there you could see where the code is waiting / busy. could it be some xml parser uses a xsd/dtd which is not available. If production server is firewalled, maybe the server is just trying to download the schema/dtd and finishes on a timeout of approx 4 seconds?

I will have to profile your application to find out where your CPU bottleneck (if it's a CPU bottleneck) is, or where your network bottleneck is. Because JSF uses value binding which can do lots of things, any badly written/badly used bean can be at cause (like a bean loading 50.000 items for a database at each request). Simple suggestion: when you load a JSF page, go in a console to your solaris station and run a kill -3 JVMpid, this will dump to the jvm's stdout a stacktrace of all running threads. From there you could see where the code is waiting / busy. could it be some xml parser uses a xsd/dtd which is not available. If production server is firewalled, maybe the server is just trying to download the schema/dtd and finishes on a timeout of approx 4 seconds? I am using Myfaces tomahawk 1.1.5, Weblogic 8.1sp4, Facelets 1.1.12. One application uses Oracle ADF and the other Ajax4Jsf/Richfaces. Thanks in advance for any pointers.

RE: Does MyFaces 1.2 require JSP 2.1?
No.. RI just makes a test on the JSP-version and disables certain stuff, when it detects a J2EE 1.4 environment (as in TC 5 and WLS 9.2). It then relies on facelets to provide certain functionality... Sounds like MyFaces is a bit harsher on the user here than the RI. OK... JSF 1.2 officially needs JEE 5. BUT... 1:0 for RI to allow for the gracefull degradation. Just set up a 1.2 RI-app in TC 5.x and watch the log when starting up. You will notice some entries like INFO: JSF1027: [null] The ELResolvers for JSF were not registered with the JSP container.

RE: why tab pane submits/validates all tabs
I wonder whether it would be possible to define a form inside each tab to force a partial submit. It just raises the question, whether the tabbed pane automatically adds a form around the complete tab-widget, or just on the clickable tabs,... From the usability I would argument, that the click on the tab automatically should throw away the form-content on the tab, because it is not a form-related button (which should be below the input-fields). And ALL links (which includes the tabs outside the input-form) should be considered as form-unfriendly navigation = not submitting the form... This would also make it possible to get rid of the Javascript on each link (no need to submit a form). regards Alexander -Original Message- From: Alexander Wallace [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 05, 2007 11:08 PM To: MyFaces Discussion Subject: Re: why tab pane submits/validates all tabs Ok... i guess that's then the expected behavior, just not what I expected... thanks!

how can I access a constant integer value within an el-statement.
I like to do something like:

And ACL is defined as:

Yes, it sucks but this is the JSF spec. Well, actually the JSF
spec says:
quote
The syntax of a value binding expression is identical to the
syntax of
an expression language expression defined in the JavaServer
Pages
Specification (version 2.0), sections 2.3 through 2.9, with the
following exceptions ...
/quote
where the exceptions are not relevant in this case. And the JSP
spec
says that a.b and a[b] are:
quote
used to access maps, lists, arrays of objects and properties of
a Java-
Beans object
/quote
See:
http://java.sun.com/javaee/javaserverfaces/download.html

http://java.sun.com/products/jsp/syntax/2.0/syntaxref207.html#1010522
Therefore to get access to static constants working, what is
needed is
to ensure that the data you want *is* a Java Bean Property
(read-only in
the case of constants). The ways to do this are:
1. add a getter method, getCONSTANT
2. add a getter method for a Map which provides access to the
constants
3. play clever tricks with a BeanInfo class.
If you want to solve it once and for all, consider implementing a custom
PropertyResolver to do the dirty work. The goal would be to translate
something like
#{foo.static.BAR}
into the value of the static constant BAR on whatever class foo resolves
to. The getValue() method for this custom PropertyResolver would need
to do something like this:
* If the property name is static, create some sort of proxy object
that is configured with the class of the base object and return that.
* Else if the base object is an instanceof the proxy class described
above,
treat the property name as the name of a static constant, use
reflection
to retrieve the value, and return that.
* Else delegate to the previous PropertyResolver instance.
Being able to customize the evaluation of expressions is very powerful.
Also, while the concept above refers to PropertyResolver and is
therefore relevant for JSF 1.1, the same concept works with ELResolver
in JSF 1.2 (with the added benefit that your custom resolvers are used
for JSP ${...} expressions as well as JSF #{...} expressions).

The Most important part, 50%, are not shown in your diagram. Also, because the renderView will, in the end, call your backing beans to display datas, you should check that the backing beans code are not your slowing part. Last but not least, you did not give background informations on what your app is doing. Are there lenghtly process that should take more CPU than the rendering in your design? (Remind yourself that picking datas to display from bean, is part of the execution of renderView) If most of the job of your app is to display datas, it's quite normal that the renderView take most of the time spend by your application.

to pack the component in a separate jar-file and to include

You also need to tell facelets to look at your custom-taglib:
Add to web.xml something like:
context-param

param-value/WEB-INF/custom-taglib.xml/param-value
/context-param
You can add more files to the param-value, just separate each file by

I think I see why I'm getting this problem, but I still don't know if
I have a fix for it. The HtmlRadioRendererBase class uses the
SelectItemsIterator to iterate through the list of child
UISelectItems. That class' hasNext() method has the following code:
public boolean hasNext()
{
.
if (_childs.hasNext())
{
UIComponent child = (UIComponent) _childs.next();
if (child instanceof UISelectItem)
{

else if (child instanceof UISelectItems)

//todo: may other objects than selectItems be nested
or not?

getPathToComponent(child) + : must be UISelectItem or
UISelectItems, is of type : +((child==null)?null:child.getClass
().getName()));
}
}
return false;

So, for my use case to work the else clause would need to continue
searching for other UISelectItem instances. Does anybody see any
issues with that approach? If not, I'll submit a patch if I can get
it going.

c:forEach items=${section.items} var=item
f:selectItem .../
/c:forEach
div
/td
tr
/c:forEach
/table
/h:selectOneRadio
The above did not render any radio buttons. I can only assume this
is because the first child component of the HtmlSelectOneRadio
component is not a UiSelectItem. It's just a bunch of HTML. (I
guess if I was using JSP instead of Facelets, maybe the above would
work since HTML is just template text and not part of the component
tree). The UiSelectItems *are* direct children of the
HtmlSelectOneRadio. It's not that they are nested too far down the
tree. It's just that they are siblings of some other components.
So I tried this instead:
table
c:forEach items=${sections} var=${section}
tr
td${section.label}/td
/tr
tr
td
div
h:selectOneRadio id=xyz...
c:forEach items=${section.items} var=item
f:selectItem .../
/c:forEach
/h:selectOneRadio
div
/td
tr
/c:forEach
/table
This appears to work at first. Since multiple selectOneRadio tags
share the same client id the browser treats them as a single group
of radio buttons. That's the desired behavior. But, it is
impossible to submit a valid form. Each selectOneRadio tag is a
separate component tied to the same value on the backing bean. So
if the forEach loop creates 3 of them, it tries to populate it 3
times. But only one of those will contain a selection, so a
validation error occurs on the other two.
Is this the way the UISelectOne and UiSelectItem components are
supposed to work? Should a UISelectOne tag refuse to render any
UISelectItem children if it has children that are not
UISelectItem? I know my 2nd approach is invalid because it is
creating multiple components with the same value binding -
something I don't want.
Any suggestions on how I can get this to work?
Thanks,
Greg
RE: Start project?
Hi Parts of SDF Faces have been donated from Oracle to the MyFaces project and become hte Trinidad subproject. Which to use? Difficult it completely depends on your UI-requirements.

Basically the way it was written it was almost working.
The problem
was that in order for the the link renderers decode method to be
called 1 additional parameter had to be supplied.
namely,
parent_form_client_id_SUBMIT=1
This seems to work since links need to be nested within a
form to work
anyway. It does not submit the form obviously (otherwise
javascript
would be needed), this is a normal GET request with the parameters

RE: ALLOW_JAVASCRIPT
Officially the only standard component that is allowed not to work anymore is the commandlink. In JSF 1.2 the JavaScriptlessness is part of the standard, because more and more applications must be accessable (== JS-free). Therefor we must check that as many components as possible can work with JS disabled. If they are not working without JS then the doc should say so... regards Alexander -Original Message- From: Mike Kienenberger [mailto:[EMAIL PROTECTED] Sent: Thursday, July 20, 2006 11:03 PM To: MyFaces Discussion Subject: Re: ALLOW_JAVASCRIPT On 7/20/06, ragsta [EMAIL PROTECTED] wrote: a simple question: does the ALLOW_JAVASCRIPT parameter work?

RE: [newbie] MyFaces or Barracuda ??
As others have said, maybe you should consider more of a stack than just an appserver and the UI-framework Spikesource has a nice picture of components for such stacks on their website. I have not tried their stacks... but to get an idea: http://www.spikesource.com/products/corestack.html The Spring framework tries to get all of it under one hood. And judging from the growing user-population it seems to do it well: http://www.springframework.org/ JSf and therefor MyFaces play a role because they are part of the official standardized JEE stack from version 1.5 onward... Spring, by the way, can play together with JSF Guess you have some reading ;-) And most probably some more questions... - Performance and J2EE? well a full-blown J2EE container usually can help in two ways: - distribute the load on a flexible amount of hardware by clustering - distribute the load on hardware by putting different layers of the app on different machines (JSF on one, EJB's on another one, DB on a third). AND it does it in a stadardized way... This layer-distribution can also be used for security. The UI-layer goes into the DM, the backend in a secure area, with a good firewall- admin this becomes a secure setup... hth Alexander -Original Message- From: Cyrille37 [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 12, 2006 8:38 PM To: [EMAIL PROTECTED] Cc: MyFaces Discussion; [EMAIL PROTECTED] Subject: [newbie] MyFaces or Barracuda ??

My 2 cents on your original question is that barracuda is not the way to go, mainly for the reason that very few people are using it. Support for it is probably minimal. JSF vs Struts or Spring Web is a better question. I'd go JSF, whether it be MyFaces or Sun RI, for the reason that you may be more comfortable with it coming from an M$ background. Correct me if I'm wrong, but I think a component based framework like JSF is closer to building Active X web controls than using some kind of action framework like Struts. My other recommendations would be Tomcat for the app server. If you need transaction management and persistence, I'd recommend Spring and Hibernate over JEE 5.

RE: OptionalValidator - Required validator - compound components
around this. I have no idea why JSF has the required attribute instead of a required validator. One reason might be that html does not send empty values to the server, therefor the validation mechanism has nothing to work on, the trigger mechanisms do not trap that one. The required flag is checked at another moment... But that's just a possible explanation... After looking more at the source code for the optional validator framework, it doesn't look to me like it will support data tables, trees and other complex comonents that render children multiple times. Cannot garantee... I am just trying to get back into the game... Have you tried it. or just looked at the code? If you can create a small testcase (complete but reduced webapp), we can use that as a testcase... and correct the behaviour of OptValidator. regards Alexander

Okay, I am having an issue for a non-standard configuration (go figure, I think I am in the 20% just about 80% of the time) and am looking for help. I think what I have to do is continue to the update model phase even when validation fails, but I'll tell you what I am doing in case anyone has a better idea. I have a register user form. It has three child tables (t:dataTable) one for each of: email addresses, phone numbers and geographic addresses. I have done it this way so that the user can enter multiple emails, phone numbers and addresses (for example, a work phone, a cell phone, etc). These tables are backed by Hibernate configured lists (so I have a FK child tables to store these records for the user table). In my view, I have Add and Delete buttons for the tables (and rows in the table). I don't care when the user clicks and add or a delete if components are invalid within the page (I only care when they click the Register for new users or Save for existing users). I tried marking the command links as immediate, but as those familiar with JSF would know, opened a can of worms. Since data tables do not support submitted values in child components, the user's data from the data tables disappeared when the view was re-rendered. So a no-go there. So I really need the update model phase to complete. (Yes one solution would be to enable AJAX for this project and only refresh the table row for the add or the delete, but that is beyond my scope for this project). Is there a way to let validation happen, but regardless of validation errors and warnings, to go ahead and update the model and execute the action? I suppose I could use a sub-form from the sandbox, but would that not cause the input fields in the other tables to loose their values anyways since validate and updating of the model does not take place for non-subform fields (I haven't tried the sub form out yet although it sounds like a good idea)? Another option may be to use a custom component that would update the value during the validation phase, but not stop the life cycle (so that the validation still occurs, and the values would still be kept for data table rows). I think that will work (didn't think it through fully yet), but it is messy (Basically a commandLink that doesn't use ActionEvent, but a custom event that does it's work during broadcast of process validators or apply request values). Anyone have a bright idea to get around this solution? Thank you -Andrew PS - also is there any way without partial page refreshing that inputSecret fields can not loose their value when the view is re-rendered (maybe by sending a static fake value down to the client that says to use the last value and then store that last value in the user's session?)?

I was wondering if we want to make MyFaces include support for facelets natively. This should be able to be done in such a way to prevent problems for those that do not use facelets. Option 1) Add everything to tomahawk.jar including the TagHandler classes and taglib.xml file(s). This is easiest, and will not cause issues since non-facelet users will not be using those classes, and therefore if they don't have facelets in their classpath, it shouldn't matter. Option 2) Create a new myfaces jar file (tomahawk-facelets-1.1.2.jar for example) that contains only the code and configuration necessary to plug tomahawk into facelets. This is possibly more elegant but more of a pain to setup. Option 3) Maintain all this at jsf-comp. This works, but new users may not know about jsf-comp and it is harder to stay in sync with facelet and myfaces version changes (since it is not tied into the release cycle). Since facelets hasn't changed the taglib.xml structure at all, facelet version should not be a major issue. This would also make issues like what tree2 had a mute point since we could include component handlers built in to translate any non-standard logic in the Tag classes. This methodology could be applied to the sandbox as well. Once there is some code in SVN I would think myfaces developers could easily maintain their configuration for their components as well since there would be examples from other components to learn from (so even developers without facelets experience shouldn't have any issues). What do you think? -Andrew [1] http://wiki.apache.org/myfaces/Use_Facelets_with_Tomahawk

RE: [OT] Storing files outside of the web context
You could use a web.xml centext-param to pass the absolute
path to the servlet.
In my experience the getRealPath()-method more often than
not returns null. If you want to server resources from
a jar then use weblets. If you want to serve them from the
filesystem use an absolute path configured via a
system-setting of a context-param.

Absolutely. You could hard

"text/plain"; } // Set content type response.setContentType(mimeType); // Set content size File file =
new File(filename); response.setContentLength((int) file.length());
//Set headers response.setHeader("Content-disposition", "attachment;
filename=" + filename); response.setHeader("Cache-Control", "max-age=600");
// Open the file and output
streams FileInputStream in = new
FileInputStream(file); OutputStream
out = response.getOutputStream(); // Copy the contents of the file to the output stream byte[] buf = new byte[1024]; int count = 0; while ((count = in.read(buf)) = 0) { out.write(buf, 0,

RE: Components disappearing!
HI ! I am trying to make a custom component, a sortable column which is a column with an output text and 2 command buttons at its header. I extends the UIcolumn component and put a htmlPanelGrid in it header. HtmlPanelGrid contains an output text and 2 command buttons. I am trying to a assign id to these component using View as FacesContext.getCurrentInstance().getViewRoot().createUniqueId(); Now it displays everything fine for the first time. But when I click any of these buttons, cells of the column disappears and I left with empty column. Does any one have any idea why this is happening. Not really an idea what's happening... but maybe an idea how to find it out... Have you set the logging in MyFaces to the highest level? MyFaces then logs the component-tree (with usefull info) to the log and in my components that tree-logging in restore- and render-phase have helped my a lot. You can activate the logging by adding the correct log4j options... in my xml-log4j-config I have these entries: category name=javax.faces priority value=all/ /category category name=org.apache.myfaces priority value=all/ /category hth Alexander With regards Amit ps: When I don't assign ids everything works fine except that I got a warning saying automatic id is assigned to these components.
RE: Architecture question
-Original Message- If an application has 3 tiers: presentation, business, backend - in which of those would you put the JSF Model (the Backing Beans?) Usual answer: depends... ;-) When I read through the www, I have to assume that it belongs in the business tier while the rest of the JSF stuff belongs into the presentation tier, right? I often subdivide the managed beans in two groups: - the usecase beans and - the model beans I allow the usecase beans to depend on javax.faces.**.* classes but the model beans must be kept clean. The usecase beans are used to control the flow within the usecase. The model beans are pure data-keeper. It has worked in a medium-complex application, but I consider it as just ONE working model... But if you want a good architecture - shouldn't there be some sort of interface or facade centralizing the business tier access? (Like: all requests go through one gate?) For this we request that all usecase-beans make requests from the backend (persistency,...) through facades. Those facades are not allowed to have framework-dependencies. They use services, which depend on the backend-frameworks to get at the actual data. Usually they return the model-beans from above... Does anyone have a good JSF based architecture in UML (easier to talk about a diagram instead of trying to describe it with words) Not yet ;-) hth (at least (new?) ideas...) Alexander

I'll reconstruct the code, for the moment I have bypassed the

Originally loginPerson(the field itself) itself was private, made it

I have also googled for this (perhaps with the wrong terms,
like JSF
and recursive variable resolving) but that didn't came up with
much. :-)
What I don't know is whether the Variabe Resolver was specified to
also resolve in that fashion in the first place.

Hi,
I have a Variable Resolver question.
To set the scene first:
Trying to follow good practice, I build up my model classes in
XXX.model.modelClass. e.g. XXX.model.Person
For the front end, there's a package XXX.web.beans e.g.
XXX.web.beans.LoginBean
In that LoginBean I had a field declared:
Person loginPerson;
-- In the JSF page I obviously tried:
Login: #{loginbean.loginPerson.lastName} (I declared loginbean
properly in the faces-config, session scope)
Yet this continues to give me errors. (of type conversion/validation
while updating model)
Which made me wonder whether the Variable Resolver was made for this
sort of schemas after all?
If not that would be a pitty I think.
I made it work by having LoginBean extend Person but qua design I
think
this is much less elegant.
(but still way better than copy all fields again in front-end
classes -
why make a model then?!)

Is there a way to disable/sidestep converters and validators while processing an ActionListener event? Further details are provided below. The situation: -- 1. Have a date input field 2. Have a link next to the input field that is used to set a default value in the date field. An ActionListener is associated with the link. 3. When the link is clicked, the form is posted and the ActionListener method is invoked. This method sets and default value in the date field and returns. 4. Since it is an ActionListener event, JSP redisplays the same page. A well known usecase... Problem: 1. If an illegal date format has been entered into the date field before clicking the link, the converter on the date field detects an error. JSF redisplays the page with the error message. 2. Even if the date field is empty or has a legal value, other fields on the form can have bad values such that their converter or validator will detect an error. Again, JSP redisplays the page with the error message. UI Goal: Have the link set the default value and ignore any illegal fields on the form. --- At this point in time, the user in interested in defaulting the date field, not validating fields. The fields will be validated when the form is submitted. Current Solution: - 1. The link has: immediate=true set. 2. ActionListener associated with link runs early in the JSF lifecycle. This method accesses the component and sets the date value by calling component.setSubmittedValue() 3 ActionListener method then terminates JSF lifecyle 4. JSF redisplays page. Since the date component's submitted value has been modified, the default value now appears in the date field. What we found is that some fields would not show the values the user had entered before... Why We are Looking for a Better Solution: - We have other situations where the ActionListener method needs access to several fields on the form. These fields are currently not available to the ActionListener since it is invoked early in the JSF lifecycle. If the converters/validators could be disabled, the ActionListener method could run at the normal place in the JSF lifecycle. It is understood that JSF could not do the data binding for any fields where the converter fails. But all other fields would be properly bound and accessible to the AtionListener method. You might have a look at the OptionalValidators described here: http://wiki.apache.org/myfaces/OptionalValidationFramework Comments, testcases and problem-reports are welcome. regards Alexander Thanks for your time.
