RE: FacesMessage with severity ERROR do not prevent calling an action method

[Madhav Bhargava]

Hi Volkar,

Thanks for your response. I will add that to the method so that it does not 
have to be explicitly done by the developers in their action methods.

RE: FacesMessage with severity ERROR do not prevent calling an action method

[Madhav Bhargava]

True, you are right.
The problem was that the first request goes as an AJAX request submitting on a 
part of the form. If there are errors, messages are shown. Now the user clicks 
on any other control which submits the rest of the page barring the one which 
was previously submitted. That caused the action to be executed as expected 
because that part of the page is never submitted.

Sorry for the confusion and thanks a lot for your response.

Madhav

FacesMessage with severity ERROR do not prevent calling an action method

[Madhav Bhargava]

Hi,

I am using myfaces 1.1, icefaces 1.8.1 on WAS 6.0

The controller (backing bean) action methods handle RuntimeException from the 
service layer. Depending on the exception an exception handler will put an 
appropriate message into FacesContext.
For that I have created a utility method:

public static void putMessage(String key, Severity severity,
String summary, String detail) {
FacesContext.getCurrentInstance().addMessage(key,
new FacesMessage(severity, 
summary, detail));
}

In the controller this method is used to put messages. When the page is 
displayed the messages appear properly. However when a user clicks on a 
commandButton then the control goes to the action method bound to the 
commandButton. This should not happen because there are FacesMessages with 
FacesMessage.SEVERITY_ERROR. I checked immediate="true" has not been set on the 
commandButton component.

Is my understanding not correct that if there are FacesMessages with Severity = 
SEVERITY_ERROR in the FacesContext then the invoke application phase will not 
happen and the control would come back to the current page in error?

Regards,
Madhav

No problems Jakob. I really appreciate the time you have already spent.

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

Sorry for the confusion. There was some problem with log4j configuration on WAS 
6 and therefore I was not able to generate DEBUG logs out of spring security. 
The issue turned out to be a ws-commons-logging.jar. Anyways back to the issue:

In the log it shows that the filter is actually getting called but with an 
older URL. So the spring security filter configuration is fine but now it’s the 
problem only with JSF. The  thing works fine as I am doing a 
forward from index.jsp to login.jsp

If you want the DEBUG logs then I can provide them.

Madhav

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

Sorry for the delay in response. The spring security filters are not invoked at 
all when a JSF forward happens.
What we have done as a workaround is that login page has now been made a simple 
non JSF JSP. We redirect from login page to another page which is just a dummy 
page. This redirect causes spring security to set up SecurityContext properly. 
So we are able to use spring security component level authorizations properly. 
However the URL level authorization is still an issue.

Madhav

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

Yes, I am not using facelets.
I had a look at the NavigationHandlerImpl and here is the excerpt from it:

Method: handleNavigation

if (navigationCase != null)
{
if (log.isTraceEnabled())
{
log.trace("handleNavigation fromAction=" + fromAction + " 
outcome=" + outcome +
  " toViewId =" + navigationCase.getToViewId() +
  " redirect=" + navigationCase.isRedirect());
}
if (navigationCase.isRedirect() &&
(!PortletUtil.isPortletRequest(facesContext)))
{ // Spec section 7.4.2 says "redirects not possible" in this case 
for portlets
ExternalContext externalContext = 
facesContext.getExternalContext();
ViewHandler viewHandler = 
facesContext.getApplication().getViewHandler();
String redirectPath = viewHandler.getActionURL(facesContext, 
navigationCase.getToViewId());

try
{

externalContext.redirect(externalContext.encodeActionURL(redirectPath));
}
catch (IOException e)
{
throw new FacesException(e.getMessage(), e);
}
}
else
{
ViewHandler viewHandler = 
facesContext.getApplication().getViewHandler();
//create new view
String newViewId = navigationCase.getToViewId();
UIViewRoot viewRoot = null;
if (isPartialStateSavingOn(facesContext)) {
viewRoot = viewHandler.restoreView(facesContext,newViewId);
} else {
viewRoot = viewHandler.createView(facesContext, newViewId);
}
facesContext.setViewRoot(viewRoot);
facesContext.renderResponse();
}

In the above code, redirect happens properly however for a forward there is no 
RequestDispatcher.forward or ExternalContext.dispatch called. So I do not know 
where a forward happens.

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

I had added spring security code in my workspace for debugging reasons and I 
suspected that how can a new page be shown when the URL passed to the filter at 
the server is old. So I put a dummy filter in front of spring security just to 
print out the URL that is getting intercepted by spring security filter chain.

So now I find that when a JSF forward happens via NavigationHandler then there 
is no URL that is actually intercepted by the spring filter. What I saw during 
debugging was not the correct picture.

SO I am back at the same problem. The filter for JSF forwards is not getting 
invoked at all.

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

Yes, I have made the appropriate configuration for spring security filters so 
that specially in the case that you have described below this property will 
make sure that the authentication is done again.

However I do not think that it has anything to do with a stale URL being passed 
to the filter at the server side. I can understand that the browser will have 
an old URL but at the server side the URL intercepted by the filter should not 
be stale. Moreover the control is being forwarded to the correct page and the 
page is visible as well so do not know how can a old ULR be passed at the 
server side and a new page be displayed at the client side.

Madhav

Yes,the request is properly forwarded to operationsLanding.jspx and I can view 
the page. I had put a breakpoint in one of the spring security classes and I 
could see the old URL which got successfully mapped against pattern 
/**/secure/** which should not have happened.

If I have a normal JSP application where there is no JSF then it works fine. I 
meant the navigation is not handled by JSF.

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

To add if you see the spring security application config, I have the following 
set:






The URL for the outcome to be forwarded to matches the second interceptor 
pattern which is "/jsp/operations/user/operationsLanding.iface"

However what the filter receives is "/jsp/secure/hprelanding.jspx" which is the 
old URL from where the control is being forwarded. This is not how it happens 
when using jsp:forward.

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

Hi Michael,

Following are the servlet mappings:


Faces Servlet
*.faces



Faces Servlet
*.jspx




Persistent Faces Servlet
*.iface


The navigation case in faces-config.xml is:



OPERATION_LANDING

/jsp/operations/user/operationsLanding.iface



This has been configured as per the icefaces documentation. If we disregard 
spring security filter issue the forward happens properly. Spring security 
filter gets invoked once after the return "OPERATION_LANDING" from within the 
action method has been executed. The strange part is that the URL is still the 
previous one.

It is strange because when using jsp:forward from index.jsp to login.jsp spring 
security filter gets both the URL's.

What could be the issue?

Regards,
Madhav

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

Thanks for your response Jakob.

What you have mentioned is already known to me. That is the reason I have put a 
FORWARD
For Spring security filter.

I should have made it a little more clear. Apologies for that. The forward from 
index.jsp to login.jsp is via . These are not JSF pages. This 
forward is captured by Spring security filter. However when a forward happens 
from within JSF via NavigationHandler then this forward is not caught by spring 
security filter. I am not sure why a jsp:forward forward will be caught every 
time and not when done via myfaces.

So essentially I not worried about browser showing me the previous URL because 
that is an expected behavior but the new URL is always caught by the filter 
which in my case is the exact problem.

Madhav

Spring FilterSecurityInterceptor not been called for myfaces forwards

[Madhav Bhargava]

Hi All,

I am using myfaces 1.1, icefaces 1.8.1, spring 2.5.6, spring security -2.0.5, 
WAS 6.0 (app server)

I have configured spring security for my JSF application along with SiteMinder 
as an external authentication mechanism. It works fine till a forward happens 
from within myfaces.

Here is my spring servlet filter chain declaration:


Spring delegating filter which will initiate 
the spring
security filter chain

springSecurityFilterChain
springSecurityFilterChain


org.springframework.web.filter.DelegatingFilterProxy




springSecurityFilterChain
/*
FORWARD
REQUEST


And in my spring application context I have followed the advice from spring 
forums and done necessary settings:
Excerpt is:














Now when I forward a request from index.jsp to login.jsp then the spring 
filters are called with the login.jsp URL even though the browser shows the old 
URL.

However when from within an action method a navigation case is handled then it 
is not intercepted by the spring filters at all. However if I give a 
 then it is properly intercepted with the correct URL as expected.

What can be the reason?

Regards,
Madhav

You might want to check on the following:

1.   Utilize HttpAnalyzer or any other similar tool to check what is the 
response received for every action. Since you have used Ajax in your page you 
need to check the response that you are getting back on each ajax call and 
whether it is only what should be returned.

2.   There are some optimizations that are listed on Ajax4Jsf site which in 
past has proven to be the guilty party for performance related issues.

3.   Check what is the size of the response. If the page is too large then 
you can consider introducing a gzipfilter to compress the response and thereby 
reducing the network bandwidth usage.

4.   Check if objects are not getting released. Some of the Ajax4Jsf 
components like a4j:keepAlive keep the objects in memory for longer period than 
expected.

5.   Also checked if there are too many session scoped beans and thereby 
slowly adding to memory usage and eventually affecting everything.

6.   There are other parameters in myfaces configuration like number of 
views in session. Try changing that as well.

7.   Check if the page is not heavy with different types of content 
(images, audio/video etc..). Go for incremental loading.

Madhav

pageIndexVar is set at request level for usage of child components within the 
datascroller component. IMO you will not be able to do what you wish to do.
It's the same as "var" attribute on t:datatable.

RE: GZipping JSF Response

Hi Cagatay,

I tried using the GZipFilter that comes along with ehcache as well. I 
configured the filter in web.xml and the mapping URL was just “*.jsf”. It used 
to give the same problem. Somehow the gzipped content is getting written to the 
IDE console instead of sending that to the browser.

Any pointer would be appreciated.

GZipping JSF Response

[Madhav Bhargava]

Hi All,

I have a heavy page and I am trying to reduce the response size by gzipping the 
Http Response going back to the client from the server.
Since I cannot install mod_deflate/mod_gzip on IBM HTTP server I have tried to 
use the GZipFilter (provided by ehcache) and I also tried to create my own 
custom filter.

The contents are getting zipped but when the filter writes the response, it 
prints the compressed response to the console instead of sending the compressed 
response to the browser. Can gzipping work with JSF pages?

Thanks & Regards,
Madhav

Feature to disable/enable components using JS

[Madhav Bhargava]

Hi All,

At present if you need to enable a disabled component then either you call an 
actionListener or make an AJAX call to re-render that component by changing a 
property bounded to the disable attribute of the component.

What this does is it makes a page a little heavy especially when you have many 
of such validations on a complex page. Is it not possible to have a feature 
where you can bind a JS function instead of binding a class level property to 
the disabled attribute of any JSF component?

Something like:


This will help in improving the response time of the page. If this is possible 
today then do let me know.

Thanks & Regards,
Madhav

RE: How to access session scope attributes via JSF EL

Hi Andrew,

Thanks for the response. I am setting a session attribute in custom

the property in session scope has already been set to either  true or false.

I am not sure why accessing the property is not yielding me the proper value.

Unless you set #{sessionScope.someBooleanProperty} to true it will return null,

Check if anything has been changed on the form

[Madhav Bhargava]

Hi All,

We are trying to fine tune the DAO layer where we are using Hibernate as our 
ORM. Since we have too many detached objects, every time we go and save which 
is quite often (because of implicit save) too many queries get fired and the 
application responds slowly. This happens even if nothing is changed by the 
user on the UI.

I was hoping to find a dirty flag setter in JSF where it can be checked first 
and only if the form has been changed will the call to other layers is made.

There are a couple of options that we considered:


1.   Using JS we iterate all the elements on the page and check if 
something has changed. However the JS gives an error if there are just too many 
elements on the page. Most of our pages are long and complex - don't ask me why 
- just a client requirement :(

2.   Attach value change listeners for every component that can be 
modified. What if nothing gets changed and therefore no ValueChangeEvent is 
queued. How will this be checked?

3.   Hack model update phase and try and set a dirty flag if anything is 
updated during that phase. Do not know how to do that either?

The solution needs to be light on performance. Any pointer would be really 
appreciated.


Thanks & Regards,
Madhav

Sun JSF RI 1.1_02
Tomahawk 1.1.7
Tomahawk-sandbox 1.1.7

I will create a simple JSF project and will try out the same thing and if I 
find the same behavior I will post a bug.

two radio buttons get selected

[Madhav Bhargava]

Hi All,

We have a data table (t:datatable) where the user has the ability to select 
only one row. The first column of the datatable is a radio button 
(s:selectOneRow). On selection of the radio button rest of the page is 
refreshed with values if the row selected was previously saved and has values. 
There are validations (numeric field validation, range validation etc..) 
defined on many such fields.

Here is the code for the data table:



<%-- Column for Radio button --%>












...
...

If the user adds a new row by clicking on a "Add" button, then a new row gets 
dynamically added to the data table shown above. This works fine.  The user now 
enters some invalid values for that row in the rest of the page. One toggle as 
seen in the code above, a A4J submit is made. This would mean that fields in 
the rest of the page will be validated as the current row needs to be saved on 
toggle even (implicit save functionality is a requirement).

The requirement is the save the current row and all its associated data on 
toggle. If there is an error then the selected row should be set back to the 
previous selection.

This requirement creates one problem. When there is a validation error then 
none of the action listener or action event will be invoked. The control will 
directly go from validation phase to render response phase. So when there is a 
validation error and the control returns back to the JSP then there are now 2 
radio buttons selected. This is because the model bean never got updated as it 
failed the validation.

We tried using JS to reset the radio button's selected value but we will not be 
able to set any backing bean's property using JS. So that was ruled out.

We also tried to disable the entire data table on error. All the columns get 
disabled but the radio button does not. It still receives focus, so this was 
also ruled out.

What can be a possible solution to avoid more than one radio button to appear 
selected on the UI?
Any help in this regard would be greatly appreciated.

Thanks,
Madhav

selectOneRow component issue

[Madhav Bhargava]

Hi All,

I am using selectOneRow component in a t:datatable. On some occasions I need to 
disable the group of radio buttons not allowing the user to toggle to any other 
row in the table.
There is a disabled attribute for this component but even if I explicitly set 
disabled="true" for this component then also it receives focus.

I found a similar issue being logged sometime back: 
http://mail-archives.apache.org/mod_mbox/myfaces-dev/200705.mbox/%3c29164240.1178678115593.javamail.j...@brutus%3e
I see the attribute now but it does not disable the component. I guess this is 
a basic flaw with the component.

I am using tomahawk 1.1.7 & tomahawk sandbox 1.1.7 along with Sun JSF RI 1.1_02

Any help would be appreciated.

Thanks & Regards,
Madhav

Your solution will not work for messages which get added to the FacesContext 
during the validation phase. Method isMessagePresent() will not be called. That 
is the reason I was looking at accessing the messages as an EL expression.
If there is a validation/conversion exception thrown then it will directly go 
to the render response phase after completing the validation phase.

I will try and use a scriptlet to get access to messages and see if that is 
going to work. Not the best way of doing things but I will have to live with 
that as of now.

Thanks for your response Simon.

Madhav

This might be an option i can consider at the moment if i do not want to
write a custom EL resolver. Also as matthias pointed out that method
invocations are going to be a part of JSF EL soon.

Thanks for your quick response. I will try it out and let you know if that
works for me. In case i come out with a cleaner solutions then i will post
it here.

Re: JSF EL does not allow method calls

[Madhav Bhargava]

You will not be able to use faceContext.messages because messages is not a
property in FacesContextImpl class. I am using Sun JSF RI and i cannot find
any property named messages/message and therefore when you invoke
facesContext.messages then it will throw a PropertyNotFoundException.

THanks,
Madhav

JSF EL does not allow method calls

[Madhav Bhargava]

Hi All,

I have a requirement wherein I have to disable UI components based on whether 
there are any error messages in the Message Queue (t:messages).
facesContext is an implicit object so I thought of using it like - 
#{facesContext.getMessages.hasNext} However when it was not working because you 
can only specify properties of a class and JSF variable and property resolver 
will then internally try and call the getter/setter of that property.

I find that rather limiting because I do not find the need to define a class 
level property when all I need is to process and output a Boolean. Is there any 
way apart from overriding the PropertyResolver/VariableResolver?

Thanks,
Madhav

RE: How to display popup using t:popup only on click of a link?

We made a custom control during that time, however I would suggest that you 
have a look at ContextMenu component from richfaces. It will hopefully satisfy 
your need.

RE: Using Ajax with MyFaces

[Madhav Bhargava]

What you can do is the following:

When the page loads show a loading gif using a status component from ajax4jsf 
which will then change to data table when the div in which the table is 
contained gets some data to be displayed. Either you can enclose the other 2 
data tables in a4j:outputPanel or just re-render them using support component.

I believe that if you have any further queries regarding a4j library then this 
will not be the correct forum to post your queries. Richfaces has better AjAX 
support than myfaces at present.

Your requirement is not clear. You can always pre-populate a backing bean which 
is associated to the page and then transfer control to that page.
Alternatively you can call a javascript on page load and then issue an AJAX 
submit. Put the data table in a4j:outputPanel. When the page is refreshed the 
data table will then have the data that you desire.

How to get hold of the event queue in JSF?

[Madhav Bhargava]

Hi All,

I am using Sun JSF RI 1.1_02, Tomahawk -1.1.6, tomahawk-sandbox-1.1.6, 
richfaces-3.1.6

I have a page where there is are 2 drop downs:













And there are 2 input text boxes: (Note: I am not using required="true" because 
there is a problem with Sun JSF RI with the way they handle messages on 
validation errors)











Now on change of the second drop down I need to refresh the values in the text 
boxes but not validate them. However I only need to validate them when an input 
button is clicked. Now I enclosed these text boxes in a  component. 
After which the validation errors were gone when the page got submitted using 
ajax4jsf support but since the subForm component was not submitted the 
processModelUpdates was not called for the components within the subForm. Upon 
re-render of a4j:support then show the older values.

I guess I will not be able to use s:subForm along with a4j:support. Is there 
any way I can get access to eventQueue so that I can check what are the events 
queued by the end of apply request phase. Looking at the events I can check in 
my validators whether to validate the field or not. That is the only solution 
that comes to mind right now.

However I am stuck because I do not know how to get hold of the event queue. 
Can anyone throw some light?

Thanks,
Madhav

s:subForm and a4j:support created re-rendering problems

[Madhav Bhargava]

Hi All,

I am using Sun JSF RI - 1.1_02, tomahawk 1.1.6, tomhawk-sanbox-1.1.5

Later versions of tomahawk include subForm component. However we are stuck up 
with the above versions and therefore we use s:subForm instead of t:subForm

We have a drop down. On change of that drop down we call a method via 
a4j:support and try and re-render different components on the page. The problem 
is that some of the components (part of re-render list) are inside another 
subForm and those components do not get re-rendered and for them update model 
is not been called, so they always show the last value.

How can I force an update model for the components inside the subForm so that 
when re-rendered they show updated values?

Thanks,
Madhav

Initially i tried doing that using a call to a method on click of a link but 
then i realized that it will still output the entire HTML including the left 
navigation, header and footer. I created a custom component to capture the part 
of the Page. I provided 2 attributes - targetPath - where to save the Html 
output and isCaptured - to conditionally capture

It works well. Thanks for all your help.

Madhav

Subject: Attach the current JSF View as an attachment

Hi All,

I have a rather unique requirement - On a JSF page I have a command button. On 
click of this button I want to capture the generated HTML for the current view 
I am on, truncate the left navigation, header and the footer. Extract the body 
HTML and open a save dialog box to save this HTML page with only body as 
attachment.

Any ideas of how it could be done using JSF?

t:inputCalendar component converter problems

[Madhav Bhargava]

Hi All,

I wanted to decorate the default converter that comes along with 
HtmlCalendarRenderer class for  component.

I was able to actual processing of converting string to Object to the 
HtmlCalendarRenderer class using the following code:

Method: getAsObject()
UIInput inputComponent = (UIInput)component;
inputComponent.setConverter(null);
String rendererType = inputComponent.getRendererType();
Renderer renderer = 
facesContext.getRenderKit().getRenderer(inputComponent.getFamily(), 
rendererType);
Object convertedValue = renderer.getConvertedValue(facesContext, component, 
value);

The converter in question is a generic converter and applies to any UIInput 
component. The problem is with getAsString method. The component nor its 
renderer does not expose any method through which I can delegate the conversion 
to String to the actual getAsString class. What I was looking for was access to 
the default converter for any component if none have been specified, but did 
not find a way to get hold of it.

Is there any way around if I need to have a generic converter for all UIInput 
type components to act as a decorator?

Thanks,
Madhav

Yes you are right. What I was talking about was a simple hack. For specific 
messages like the ones that are generated during the render response you do not 
add it to the FacesContext. Instead you maintain them into a separate list 
whose scope is say conversation scope rather than a request scope. When the 
page is rendered, onbody is called which will see if there are any messages. 
Component like t:messages will inherently read from FacesContext. You can 
create your own component extending say t:messages and read from a different 
source as well.

One quick solution can be to call a javascript function on onload. This 
function can do an ajax submit and re-render the status area of your JSP. If 
there are any error messages then that will displayed else nothing will be 
displayed. 
If you want more control then do not add the FacesMessage to the FacesContext, 
instead handle it yourself.

Madhav

component's strange behavior when used with Tiles and Sun JSF

[Madhav Bhargava]

Hi,

I am using Sun JSF 1.1_02, Tomahawk 1.1.6 and struts tiles and RSA 7.0 
(websphere runtime 6.0) as the development IDE.

I have the following code in my JSP:





I took the Messages.properties file from within jsf-impl.jar and overrode:
javax.faces.component.UIInput.REQUIRED=Validation Error: Value is required for 
{0}

When the JSP page gets rendered I submit the page leaving this required field 
as blank. As expected an validation error message is shown on the screen, but 
the bad part is that the component ID of the component is not displayed.

The following is displayed:
Validation Error: Value is required for {0}

As you can see the parameter should have been replaced by the ID of this 
component. This is rather strange.

Can anyone point out the problem here?

Thanks,
madhav

extend tomahawk sandox selectManyPickList

[Madhav Bhargava]

Hi All,

I have a requirement where I have 2 lists (left and right) and the following 
behavior is required:


1.   The user can only select one item from the left list to be moved to 
the right.

2.   The user can only choose one item either from the left or the right 
list. This will make sure that if there are any javascript events invoked the 
select value will only be a single item.

Tomahawk sandbox has a component s:selectManyPickList defined. It meets the 
basic requirement of a typical picklist however to my dismay it does not 
provide control to the user to allow multiple/single selection while moving 
elements between lists or selecting items from either list to invoke some 
external events.

The following HTML code gets generated by this component:

  Fertility Drugs
.

I would have been happy if the component user had control over setting of the 
"multiple" attribute.

I tried to find the code for sandbox components but was not able to locate it. 
I was thinking of extending this component and adding an additional attribute 
which will give me the required behavior.

Does anyone know if I can get the above mentioned behavior without extending 
the component in its current form? If that is not possible then it will be 
great if I can get some pointers to where I can find the sandbox code so that I 
can have a look at the component classes.

Thanks,
Madhav

Can tomahawk be used without myfaces

[Madhav Bhargava]

Hi All,

I am using the following JSF jars provided as part of websphere 6.0 server lib:

Jsf-api.jar - present in AppServer/lib
Ws-jsf.jar - present in AppServer/lib
jsf-ibm.jar - present in WEB-INF/lib

Since the JSF RI provided by Sun and IBM do not have inherent support for Tiles 
I thought of using Tomahawk JspTilesViewHandlerImpl. So I included tomahawk 
1.1.5 binary in the WEB-INF/lib

I changed the faces-config.xml to have  point to 
org.apache.myfaces.tomahawk.application.jsp.JspTilesViewHandlerImpl

Since I was still not using any of the tomahawk components I did not include 
the extensionFilter (org.apache.myfaces.webapp.filter.ExtensionsFilter) in 
web.xml.

When I tried deploying my application it gave an exception whose stack trace is 
attached with this mail. The same exception was thrown even after I had 
configured extensionFilter in web.xml

Can tomahawk (1.1.5 or 1.1.6) be used with the JSF RI provided as part of Sun 
and IBM? In other words can tomahawk be used without using myfaces as the RI? 
Ideally it should but I have noticed that in the JSF world of today things are 
far from ideal.

Any help would really be appreciated.

Thanks,
Madhav

RE: Running into NullPointerException when running Myfaces + tiles on WebSphere 6.0

Even if you make a custom classloader, would it really help because eventually 
the websphere will follow the delegation model of parent first to load the Sun 
RI jars first and then it will hand over the control to the custom application 
class loader.

Unfortunately the parent_last option also does not work at the module level.

WebSphere 6.0

Hi All,

I am using Myfaces 1.1.5, tomahawk 1.1.5, struts-tiles, ajax4jsf on Websphere 
6.0 and i am running into an exception (stack trace is attached with this mail)

I have already gone through the link 
http://wiki.apache.org/myfaces/Websphere_Installation and done loads of 
googling but nothing seems to resolve the problem.

Setting PARENT_LAST on Class Loader option at MODULE level does not solve the 
problem. Webshere still picks up the Sun RI jars (jsf-api.jar and ws-jsf.jar) 
that are bundled along with Websphere 6.0.

We cannot remove these jars because we have a shared production environment and 
there are other applications that are using the RI implementation instead of 
myfaces.

Any suggestions would greatly be appreciated. It is too late in the project too 
move to facelets :(.
If this problem cannot be solved then please suggest some alternate templating 
frameworks which will work well with JSF.

Regards,
Madhav

Re: Running into NullPointerException when running Myfaces + tiles on WebSphere 6.0

[Madhav Bhargava]

Hi Johannes,

If you read the article again you will notice that there are 2 sections -

One section contains the steps for making myfaces work after removing the
Sun RI jar files and using Parent First.
The other section contains the steps for making myfaces work without
removing Sun RI jar files and then using Parent Last.

As i have mentioned earlier on that option of removing the Sun RI jar files
is not an option as we have a shared production environment and therefore we
cannot go for option one.

thanks,
M

Re: Dependency Injection in Validators

[Madhav Bhargava]

Seam supports this kind of injection via @in and @out annotations
http://www.javabeat.net/jboss-seam/2007/06/jboss-seam-introduction/

Another way would be to integrate Spring + JSF.
Yet another way would be to manage business layer with Spring and then you
an instance of a bean which implements ApplicationContextAware to get you
any spring bean reference to any other bean not managed by Spring.

t:popup problems still persist

[Madhav Bhargava]

Hi All,

I am using myfaces 1.1.5, tomahawk 1.1.5 in my web application which runs on
IE 6. I have the following structure in my JSP:


   
   

Content for the popup

   



The problem is that the t:popup is not visible when it is nested inside a
popup. There was a similar discussion way back in 2005 on this list and i
was not able to see any solution coming out of that discussion. Here is the
thread:

http://mail-archives.apache.org/mod_mbox/myfaces-users/200512.mbox/[EMAIL 
PROTECTED]

Unfortunately the problem still remains un-resolved. Is there any solution
to this problem or we need to look at an alternative component?

Thanks for any help.

Regards,
Madhav

tomahawk inputFileUpload component times out for large files

[Madhav Bhargava]

Hi All,

Following is the environment i am working with:

Weblogic 8.1 sp4
myfaces 1.1.5
tomahawk 1.1.5
IE 6.0 SP2

In my application i am using inputFileUpload component which internally uses
apache commons FileUpload. For larger files the request times out and throws
the following exception:


11:04:45,622 ERROR MultipartRequestWrapper:96 - Exception while uploading
file.

org.apache.commons.fileupload.FileUploadException: Processing of
multipart/form-data request failed. Read timed out

at org.apache.commons.fileupload.FileUploadBase.parseRequest(
FileUploadBase.java:429)

at
org.apache.myfaces.webapp.filter.MultipartRequestWrapper.parseRequest(
MultipartRequestWrapper.java:85)
..

I google a bit for a resolution but did not find any concrete solutions to
the problem. I went into the tomahawk source code and i found that the
following peice of code causes that exception:


List requestParameters = null;
try{
*requestParameters = fileUpload.parseRequest(request);
*} catch (FileUploadBase.SizeLimitExceededException e) {

// TODO: find a way to notify the user about the fact that the
uploaded file exceeded size limit

if(log.isInfoEnabled())
log.info("user tried to upload a file that exceeded
file-size limitations.",e);

requestParameters = Collections.EMPTY_LIST;

}catch(FileUploadException fue){
   * log.error("Exception while uploading file.", fue);
*requestParameters = Collections.EMPTY_LIST;
}

I did not find any property in the component tld documentation that would
help me set a timeout and overwrite the timeout defined at the server.

Any help would be greatly appreciated.

Regards,

Madhav

extended ASCII characters not shown properly on JSF page

[Madhav Bhargava]

Hi All,

We have an application which supports extended ASCII characters.
For instance characters like: å, ö, Ç, (c) are a part of content.

I am using myfaces 1.1.5, tomahawk 1.1.5
There are different read only input text fields where content is displayed
to the user. Special characters are part of this content.

When the page comes up then the characters are garbled and a rectangular box
is shown for any extended character. I believe that the encoding is not
happening correctly. Got through the following link which lists down all the
HTML escape characters:
http://www.theukwebdesigncompany.com/articles/entity-escape-characters.php

Character: (c)  - Proper encoding should be © The value that comes up is
� which is rather strange.

I have tried setting the charset of the JSF to both ISO-8859-1 and UTF-8 but
things have not changed.

Any help would be greatly appreciated.

Thanks,
Madhav

Hi All,

Environment:

not always happens.

Following is the code in the JSP:

We have a label and an input text next to it. Place the cursor on the input

RE: disable input text box generated from t:inputFileUpload

Hi Andrew,
 
Thanks for the reply.Ideally we should have a feature similar to 
"disableOnClientSide" for t:inputFileUpload component. I am not sure about 
others but i feel that on many of the UI's the user is required to necessarily 
browse and not enter it manually to avoid user errors.
What you have suggested is a patch. I had tried implementing it but faced some 
problems.

input file is not stylable (IE lets you do a little). There are many
hacks out there to style it. Some involve putting an image over it,
and such. Just google for searches like "input file css style".

If you set the width small enough, the text box goes away. The problem
is that the font on the button can change per user and per browser
vendor, so it is near impossible to know how wide to make it.

disable input text box generated from t:inputFileUpload

[Madhav Bhargava]

Hi All,

I have a requirement where the user should not be given control to directly
type in the path of a file. The user needs to necessarily click the browse
button and then the path will then be populated in the "disabled on client
side" input text that gets generated via this component.

I could only find one disabled property on that component but that does not
do the trick.

Do you have any suggestions?

Thanks,
Madhav

set up myfaces to run in a clustered environment

[Madhav Bhargava]

Hi All,

We have already developed an application using JSF which is now going to be
moved to a clustered environment.
We have the following parameters set in web.xml:

1. org.apache.myfaces.SERIALIZE_STATE_IN_SESSION set to false
2. javax.faces.STATE_SAVING_METHOD set to server

What are the changes required to make myfaces work in a weblogic clustered
environment? I was unable to find any documentation on the net for the same.

Any help will be appreciated.

Re: How to implement a vertical splitter in a data table

[Madhav Bhargava]

Hi Adrian,

Couple of problems with using a t:dataList:

1. No sorting functionality available by clicked on column headers
2. Two data Lists will not be connected
3. Splitter can also be moved which is how it is normally implemented in
non-JSF world

Is there any other component/JSF library that has this feature?

How to implement a vertical splitter in a data table

[Madhav Bhargava]

Hi All,

I have a requirement in which i need to implement a vertical splitter in a
data table. This vertical splitter will divide the data table into 2 parts.
Each part of the data table will have a horizontal scroll. The user can keep
one side of the data table as it is and scroll horizontally on the other
side of the data table.

I am not sure if it can be implemented using t:datatable. Any help will be
appreciated.

I just cannot make InputSuggestAjax component work

[Madhav Bhargava]

Hi All,

Environment:
Weblogic 8.1
JDK 1.4.2.x
Myfaces 1.1.5
Tomahawk 1.1.5
Tomahawk sandbox 1.1.5

I have taken the lead from the example at http://www.irian.at which is again
present at http://wiki.apache.org/myfaces/InputSuggestAjax

Instead of an Address bean i have a KeyValuePair bean. This bean has 2
properties - key (String), value (Object). I want to display the values in
the drop down that would come up when the user starts typing something and
then the selected bean will then be passed to the model. Using the key field
of the selected bean i will then compose a query for the database.

JSP code:

   


Methods in Controller/Managed bean for inputSuggestAjax component:

   public List suggest(String prefix) {
   List matchingList = new ArrayList();
   Iterator iter = items.iterator();
   while(iter.hasNext()) {
   KeyValuePair bean = (KeyValuePair)iter.next();
   if (bean.getValue().toString().startsWith(prefix)) {
   matchingList.add(bean);
   }
   }
   return matchingList;
   }

   public String getLabel(Object selectedBean) {
   if (null != selectedBean && selectedBean instanceof KeyValuePair) {
   Iterator iter = items.iterator();
   while(iter.hasNext()) {
   KeyValuePair bean = (KeyValuePair)iter.next();
   if
(bean.getKey().equals(((KeyValuePair)selectedBean).getKey()))
{
   return (String)bean.getValue();
   }
   }
   }
   return null;
   }

Just to test i am populating the items List in the controller itself:
   public InputSuggestAjaxController() {
   items = new ArrayList();
   items.add(new KeyValuePair("1", "India"));
   items.add(new KeyValuePair("2", "US"));
   items.add(new KeyValuePair("3", "Russia"));
   items.add(new KeyValuePair("4", "China"));
   items.add(new KeyValuePair("5", "Indonasia"));
   items.add(new KeyValuePair("6", "Iran"));
   items.add(new KeyValuePair("7", "Uganda"));
   }

Custom Converter for this component:
   public Object getAsObject(FacesContext context, UIComponent component,
String value)
   throws ConverterException {

   if (null != value) {
   KeyValuePair bean = new KeyValuePair();
   bean.setKey(value);
   return bean;
   }

   return null;
   }

   public String getAsString(FacesContext context, UIComponent component,
Object value)
   throws ConverterException {
   if (null != value) {
   if (value instanceof KeyValuePair) {
   return (String)((KeyValuePair)value).getValue();
   }else if (value instanceof String) {
   return value.toString();
   }
   }
   return null;
   }

public class KeyValuePair implements Serializable {
   private String key = null;
   private Object value = null;
   //getter and setter methods...
}

The problem is that when the user starts typing nothing is suggested even
though the control goes to suggest method and a list is created properly.
getLabel method gets called and even the method in the converter gets
called. But somehow it does not show up.

Browser that i am using is IE 6

Any help in this regard will be greatly appreciated.

Regards,
Madhav

Re: t:navigationMenuItem with icon and label?

[Madhav Bhargava]

Yes, that is a problem with this component. I tried using the same to render
both the icon and the label but then it does not work as expected.

U can use t:commandNavigation2 component instead.

How to display popup using t:popup only on click of a link?

[Madhav Bhargava]

Hi All,

 

I have a requirement where I need to mimic the directory structure of
windows. The tree directory structure can be changed by right clicking
on one of the items, similar to what windows has.

What I have done is the following:

 

I have defined a tree structure using t:tree2 component. The only
problem with that component is that it does not restore open state as
the t:panelNavigation2 component does. Each of the facets in the tree
encloses just a t:commandLink component. This command link component is
wrapped with t:popup.

 

So now when the user hovers over a node in the tree (which is a link)
then a popup is displayed. All this is fine but I have a few problems:

 

1.  I want the popup to be displayed on click of the link and not on
mouse over event. How can I change the behavior of t:popup so that it
gets displayed on mouse click event and not mouse over event?
2.  Say if there is some way in which the first requirement can be
met then how do I pass the value of the node back to the backing bean?
It can be done by having a hidden variable and having an onclick event
on the node (since each node is also a link). But I was looking at using
t:updateActionListener and then passing back the value of the node and
setting a property in the backing bean. How do I access another
component's value and pass it on the click of a menu item (a command
button) in the popup.

 

To clarify point number 2:

 

Consider the following tree layout:

 

Root

   DummyNode1

DummySub1.1

   DummyNode2

DummySub2.1

DummySub2.2

DummySub2.3

 

Now when I click DummyNode2 then a popup with the following content
should be shown:

 

Add Sub Folder

Modify Folder Properties

Etc...

 

So now when the user clicks Add Sub Folder I need to pass DummyNode2 to
the backing bean. What is the best way to do this?

 

Thanks,

Madhav

Re: action not working in t:navigationMenuItem

[Madhav Bhargava]

My apologies. Was not in the correct frame of mind.
You can specify an outcome directly as the value for an action attribute.
Make sure that the action outcome is present in the faces configuration file
in one of the navigation rules.

Re: not displaying icon in t:navigationMenuItem

[Madhav Bhargava]

I am not sure what you are trying out here. I assume that you are using
navigationMenuItem inside t:panelNavigation2 component. If yes then the last
time i worked with this component i had major problems displaying icon along
with text in the menu. That is the reason i shifted to using
t:commandNavigation2 component instead of using t:navigationMenuItem

I am not sure what is the problem that ur facing unless you give me more
information.

A litle Help - building myfaces in eclipse using maven

[Madhav Bhargava]

Hi All,



I have followed the instructions @
http://wiki.apache.org/myfaces/Eclipse_IDE to build myfaces in eclipse.



"mvn install" and "mvn eclipse:eclipse" works fine and it builds all the
sub-projects successfully. The next step as per the documentation is to
include all the sub-projects individually. I import all the subprojects
by repeatedly pointing the root location to the subproject root. I have
installed a maven eclipse plugin as well and after importing all the sub
projects I enable them to use maven.

I have also specified the dependencies on shared libraries as per the
documentation in the same site.



When it starts building then it gives the following error:

3/23/07 1:55:28 PM IST: Project build error Cannot find parent:
org.apache.myfaces.maven:myfaces-master for project:
org.apache.myfaces.tomahawk:tomahawk-project:pom:1.1.6-SNAPSHOT

3/23/07 2:33:42 PM IST: Reading /myfaces-shared-core/pom.xml

3/23/07 2:33:42 PM IST: Local repository folder "" does not exist



There is a local repository - @ d:/maven/repository where all the
dependent libraries were imported at the time "mvn install" was run.



Am I missing something here? Please help.

Madhav

Re: Wierd behavior - valueChangeListener does not get called with selectOneMenu

[Madhav Bhargava]

Hi Mike,

Thanks for the reply. Yes you are right, i went thru the documenation again
right after i had posted this query . The javascript function that i need to
call is *_*submit()

If there is a subForm then only this requirement arises else you can simply
give onchange="submit()" and it will work.

I will check out the submitOnEvent component in sandbox.

Thanks again.

If possible, I'd replace "onchange=document.forms[0].submit();return
false;" with the submitOnEvent sandbox component.

My guess is that you need to use the javascript documented here:

http://myfaces.apache.org/sandbox/subForm.html

I've had no issues with a subForm, a selectOneMenu, a submitOnEvent, and a
commandButton triggering an action when an option is chosen from the menu.


The other possiblity to investigate is if validation is failing for some
other component on your page -- make sure you've got a t:messages component
for debugging.

Wierd behavior - valueChangeListener does not get called with selectOneMenu

[Madhav Bhargava]

Hi All,



Following is the JSP code:







x- Cut x   



















x- Cut x







In the above code we have a select one menu component. If the user
changes the selection then an onchange event is fired which will then
submit the form. Once the form is submitted then in process validations
phase the ValueChangeListener should be called.



Weird behavior:

With the above piece of code the value change listener does not get
called even when the user changes a selection in the drop down
component.

However if you add - immediate = "true" then the ValueChangeListener is
called.

I added  to the JSP to check if there were any validation
errors which would cause the JSF to skip directly to the render response
phase. But there are no validation errors.



There is another observation that I made:

If I remove  component, then with the above code the
ValueChangeListener is called as expected.



Is this a problem with  component?

Madhav

Thanks a lot Simon for the insight. I really appreciate it.
When is this //TODO going to be fixed/implemented?

Thanks a lot Simon for all the help. I will have to debug the component.
If I find something interesting then I will share with the list.

RE: how do you pass/set parameters upon ActionListener execution?-puzzled

[Madhav Bhargava]

Hi Simon,

The version of Myfaces that I am using is from a nightly build version
1.1.5.
Tomahawk version is 1.1.5 as well (some nightly build)

displayText is a String property and getter and setter have been
generated using Eclipse so I am sure that there is no problem with the
signature.

It should not be a problem with getter and setter as literal String
values are getting set properly in the backing bean.

Regards,
Madhav

RE: how do you pass/set parameters upon ActionListener execution?- puzzled

[Madhav Bhargava]

As I mentioned in point number 2 it works. displayText property in the
backing bean will get populated with "dummyValue"

The immediate inference of this result was that there is something wrong
with my EL expression. But then when I used  tag with the
same EL expression it outputted the correct value.

This means that there is nothing wrong with the EL expression. The key
is properly defined in the Messages.properties file as well.

RE: how do you pass/set parameters upon ActionListener execution? - puzzled

[Madhav Bhargava]

Hi Werner,

I double checked the jsp and the backing bean but it just refuses to
parse the EL expression.

This is what I have done:

Jsp Code:






In the backing bean I just defined a String property with the name
displayText.


Following is the observation:
1. The displayText in the backing bean is null. In other words the EL
expression does not get parsed resulting in a null value.
2. If a literal string is given in place of an EL expression then the
value is correctly populated in the backing bean.
3. Based on the result from point number 2 - I tried just outputting the
value of the EL expression using:  The same expression is now parsed
properly and the value appears on the page. This means that there is
nothing wrong with the EL expression.

I am not sure what is going on? Why will  refuse
to parse an EL expression that references a message bundle?

Madhav

Re: date in jenia calendar is off by one

Hi Andrew,

When you say user's locale do u also mean that the the tag will use the
timezone information from the user's browser instead of using the server
timezone?

could you throw some more light on it?

RE: how do you pass/set parameters upon ActionListener execution?

[Madhav Bhargava]

Hi Werner,

Yes, you are right. But I still cannot get the values in my backing
bean.

Jsp code:







BreadCrumbNavigator.java (managed bean named as per config file is
breadCrumbNavitatorBean)

private BreadCrumbParticipant participant = null;

public BreadCrumbParticipant getParticipant() {
if (null == participant) {
participant = new BreadCrumbParticipant();
}
return participant;
}

And there are setter method as well.

Now when I access participant in the action listener method
-updateBreadCrumb, then the participant itself is not null but the
displayText property set using t:updateActionListener is null.

Any ideas what is going wrong here?

Regards,
Madhav

how do you pass/set parameters upon ActionListener execution?

[Madhav Bhargava]

Hi All,



I have a requirement wherein I have to pass some values when an
ActionListener is invoked.

I am aware of 2 ways:



1.  f:param
2.  t:updateActionListener



The only problem is that both of the above only do what they do when an
action method is invoked. Since I want the values inside my
ActionListener method none of the above will work for me.

The only way left for me as of now is having a hidden field and writing
an onclick javascript which will then populate the hidden field with the
value that I want.

I am not sure whether having hidden fields to hold values is a good
solution.



Is there any other more elegant way to pass in values which can then be
accessed from inside the ActionListener method?



Rgds,

Madhav

RE: date in jenia calendar is off by one

[Madhav Bhargava]

It is not a problem with Jenia calendar. It is the timezone that is used
to convert the submitted value at the server side.

To make sure that the server JVM timezone is taken use
 tag. Now you can set the system timezone to anything
that you want.

It is obvious that the problem is not in jenia callendar

2007/3/6, raindogs <[EMAIL PROTECTED]>:


I'm attempting to implement the jenia calendar and, while it all seemed
great
at first, I now realize that I'm getting an off-by-one error on the day.
In
the test I just ran, I selected March 15th as the date. The input box
displayed "03/15/2007", but the value that actually gets passed into the
backing bean is "Wed Mar 14 19:00:00 CDT 2007".

I'm really scratching my head on this one, as I haven't heard of anyone
else
having this problem. All of the relevant info is below, any help would
be
much appreciated.

Thanks,

activeOnViewId attribute does not work as described in an earlier thread

[Madhav Bhargava]

Hi All,



I have left navigation menu ( and embedded
 components) and a breadcrumb component.

To keep both in synch I added activeOnViewId to the
 components. But when the breadcrumb is clicked
and the control is taken to another view ID then the previously
open/selected left navigation menu items do not change any state.



Say for instance my breadcrumb says - Home > Inbox

My left Navigation menu state - Message Center

  >> Inbox



Now when I click on breadcrumb "Home" link then the left navigation
should change to "Home" and the Message Center should close and be in a
not selected state. This does not happen even though I have added proper
view ID's to each of the links.



Any reason of why this will not work?



Rgds,

Madhav

Re: how does UICommand execute the action binding?

[Madhav Bhargava]

Thanks Mike,

So what i understand is that if only  is given, then
irrespective of the outcome the control will go to the view id specified.
For instance the folllowing rule is define din the faces config file:

  /bingo.jsp
  
#{sombean.someAction}
/tringo.jsp
  


Does the above rule mean that if someAction method is executed then
irrespective of the outcome the control will always go to tringo.jsp? If my
interpretation is correct then can you think of any place where this might
be used?

Now consider a second example:


  /bingo.jsp
  
#{sombean.someAction}
success
/tringo.jsp
  


Does it mean that only if the output after executing someAction is success
only then the control will go to tringo.jsp?
If that is the case then why not just give the , why is the
combination of both the tags is required?

Consider a third case:

  /bingo.jsp
  
#{sombean.someAction}
/tringo.jsp
  
  
success
/tringo123.jsp
  


Now if someAction method is executed and the outcome is success then where
will the control go? Will it go to tringo.jsp as defined by the first
navigation-case or will it go to tringo123.jsp as defined in the second
navigation case as both the cases are satisfied?

Re: how does UICommand execute the action binding?

[Madhav Bhargava]

Thanks Volker,

I figured that out, but still i cannot understand the usage of
.
I needed the above information because i needed to call an action method and
then transfer the control the navigation handler programmatically. I was
able to achieve the same by first creating a MethodBinding, invoking it,
getting the return value as an outcome and passing the same to the
handleNavigation method of the NavigationHandler.

It worked for me.

RE: how does UICommand execute the action binding?

[Madhav Bhargava]

One more thing:

 

Can anyone explain the parameters that are required in the
handleNavigation method. Why is fromAction and outcome both required?

Also to properly identify   also might be
required?

 

Does handleNavigation handle that implicitely and is therefore not
required to be a parameter?

Subject: how does UICommand execute the action binding?

 

Hi All,

 

HtmlCommandLink and HtmlCommandButton extend UICommand component class.

UICommand creates 2 MethodBindings - action and actionListener.

 

I was looking at the code for UICommand class and I could locate where
the registered actionListeners were getting executed - broadcast method
but I was not able to figure out where the action method was getting
invoked and how does NavigationHandler takes control from there on.

 

In NavigationHandler javadoc the following is mentioned:

public abstract void handleNavigation(javax.faces.context.FacesContext
context,
  java.lang.String fromAction,
  java.lang.String outcome)

 

Parameters:

context - The FacesContext
<http://java.sun.com/javaee/javaserverfaces/1.1/docs/api/javax/faces/con
text/FacesContext.html>  for the current request

fromAction - The action binding expression that was evaluated to
retrieve the specified outcome, or null if the outcome was acquired by
some other means

outcome - The logical outcome returned by a previous invoked application
action (which may be null)

 

Does it mean that if I create a MethodBinding out of an action EL
expression and then invoke the same, then will it execute the action
method and then automatically call the method specified above to
navigate to next view according to the navigation rules defined?

 

Any insight into this will be helpful.

Madhav

RE: how to avoid validation

[Madhav Bhargava]

You can have a look at:

http://www.irian.at/myfaces-sandbox/home.jsf

 

On the page you will examples for all the components of sanbox. You can
look at "SubForm - Partial validation and model update with SubForms
<http://www.irian.at/myfaces-sandbox/subForm.jsf> "

 

Other place you can look for example code is the source repository :
http://myfaces.apache.org/source-repository.html

You can browse the online source repo and check out the examples. These
will the same that are present at irian site given above.

how does UICommand execute the action binding?

[Madhav Bhargava]

Hi All,



HtmlCommandLink and HtmlCommandButton extend UICommand component class.

UICommand creates 2 MethodBindings - action and actionListener.



I was looking at the code for UICommand class and I could locate where
the registered actionListeners were getting executed - broadcast method
but I was not able to figure out where the action method was getting
invoked and how does NavigationHandler takes control from there on.



In NavigationHandler javadoc the following is mentioned:

public abstract void handleNavigation(javax.faces.context.FacesContext
context,
  java.lang.String fromAction,
  java.lang.String outcome)



Parameters:

context - The FacesContext
  for the current request

fromAction - The action binding expression that was evaluated to
retrieve the specified outcome, or null if the outcome was acquired by
some other means

outcome - The logical outcome returned by a previous invoked application
action (which may be null)



Does it mean that if I create a MethodBinding out of an action EL
expression and then invoke the same, then will it execute the action
method and then automatically call the method specified above to
navigate to next view according to the navigation rules defined?



Any insight into this will be helpful.



Regards,

Madhav

t:datatable with commandLink and parameter

Sending it again. For some reason the mail never got delivered.

Subject: RE: t:datatable with commandLink and parameter

Hi Craig,

According to the tutorial at the link:
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSFConfigure7.html

"The navigation criteria are defined by optional from-outcome and
from-action elements. The from-outcome element defines a logical
outcome, such as success. The from-action element uses a method-binding
expression to refer to an action method that returns a String, which is
the logical outcome. The method performs some logic to determine the
outcome and returns the outcome."


Does it mean that  will not execute the action method but
only derive the outcome of the action method?
If yes then what happens when the return String value is a result of the
computation that goes inside the action method?

And if it executes the action method then what is the difference from
using  as it is finally going to go to the outcome
produced by the action method.

Could you please throw some more light on  usage?

Rgds,
Madhav

where to find source code for trinidad breadcrumb

[Madhav Bhargava]

Hi All,



Can anyone point out the location where I can find the code for
Trinidadbreadcrumb component?

I have been looking for it for quite some time and I am unable to locate it.



There was a mail on the same non-availability of breadcrumb code and at that
time also the code could not be found.



Regards,

Madhav

Yes.
Unfortunately I am not able to locate the code for it in the svn for
Trinidad.

breadcrumb design

[Madhav Bhargava]

Hi All,



I am in the process of creating a component for breadcrumb generation
for my project.



I have following in mind:



1.  Create a custom component for breadcrumb, with a renderer and a
tag class.
2.  Create a model bean that will back this component and will
contain the latest breadcrumb links and their navigation outcomes. This
bean will be at the session level
3.  Create a breadcrumb event and queue that event in the decode
method of the renderer. This event will then be broadcasted to all the
interested listeners. In my case it will be the left menu which will
have to reflect where the user is.



Every page which requires a breadcrumb will have a breadcrumb tag
defined in the page.

There will be a hidden field on every page that will store the depth (or
the index of the last link) of the breadcrumb. Using this value the list
of links in the model will be updated.



Following are some problems that I am currently facing:



1.  There can be many links present all over the place which can
result in the page control going to some page else which means that
there will be a change in the breadcrumb as well. How do you capture
such events and make the breadcrumb change?
2.  How do you take care of the browser back button?



Regards,

Madhav
