FacesMessage with severity ERROR do not prevent calling an action method
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?

Madhav

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

Hi,
for clearification: does the click on the command button take place
AFTER the page with the error messages was rendered? Because if it is
so, this is the expected behavior. The messages in the FacesContext are
only available for the current request, which is the one producing the
error. If you click on a command button on this page a new request with
a new FacesContext is started. Unless this produces the same error the
messages will be gone.

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.

Hi Madhav,
the livecycle did not depend on messages in the context. To prevent
executing actions and direct skip to renderPhase you need to call
FacesContext.getCurrentInstance().renderResponse();
e.g. in your putMessage() method.

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards
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.

Hi,
as I understand you use a commandButton and as a result a different
page
(a
secured one) is rendered but spring security does not seem to intercept
the
url, is that right?
If so and if the solution used by you uses Facelets then this may be
the
problem.
When using Facelets as opposed to pure (older) jsf+jsp approach there
is
no forward when a new view is rendered that is a result of a navigation
case
forward. I've been investigating this recently. When JSP view handler
is
used it checks which view should be rendered next and does a forward to
this
new view which spring security can intercept. The Facelet view handler
however seems to load the view (xhtml) and render it without making the
actual forward. As a result no interception can happen and usually it
is
triggered with the next request.
You need to either use redirects or make GET requests to logically
separate
views - I know this is not natural with jsf versions prior to 2.0, but
this
new spec seems to change everything :-) - use can easily generate GET
requests with the new version.
Hope this helps ;)

could take a look at this log...
2010/1/18 Madhav Bhargava madhav_bharg...@infosys.com
Attached is the log file. Look for lined which have (URLInterceptor.java)
This will give you the URL that has been intercepted by the custom filter
which sits before any spring filter. Right now all it does is print out the
URL that it intercepted.
To refresh your memory here is the flow again in brief:
1. *http://localhost:9080/contextRoot/*http://localhost:9080/contextRoot/is
invoked and it internally it redirects it to the welcome page
(/index.jsp)
2. index.jsp does a jsp:forward to /login.jsp
3. User enters the credentials and as of now since we do not have
Siteminder for authentication the action attribute points to
/jsp/secure/hprelanding.jspx (first JSF page) so a redirect is send.
4. On hprelanding page an automatic click happens on a hidden command
button which calls a backing bean action method. Since I am using icefaces
the click of a button request is sent using the URL: *
http://localhost:9080/HPRE/block/**send-receive-updates*http://localhost:9080/HPRE/block/send-receive-updates
5. You will find many other URL's in between which is all caused by
icefaces.
6. The action method will do nothing but forward the request to
operationlanding.jspx page which should only be visible to users who have
ROLE_OPERATIONS however that URL never comes up. Instead the next URL of
importance is again hprelanding.jspx one.

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards
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.

I wrote a small test webapp and came to the following conclusion: JSF uses RequestDispatcher.forward(..) to render the second view. Thus the filter should be invoked for the forward. However, the filter is/was already invoked for the first request and it cannot be invoked twice for one request. Only for test reasons, remove dispatcherREQUEST/dispatcher from your filter config in the web.xml and the filter will be invoked for RequestDispatcher.forward(..), because it was not invoked for the original request. I know this does not solve your problem, but I think there is maybe a workaround for this.. I myself just don't know one..

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards
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. Regards, Madhav From: 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. Thanks, Madhav From: Michael Kurz [mailto:michi.k...@gmx.at] Hm, I thought the same first but he has attribute once-per-request set to false: security:http once-per-request=false... - Michael Jakob Korherr schrieb: Hi Madhav, I now know what the problem is. I wrote a small test webapp and came to the following conclusion: JSF uses RequestDispatcher.forward(..) to render the second view. Thus the filter should be invoked for the forward. However, the filter is/was already invoked for the first request and it cannot be invoked twice for one request. Only for test reasons, remove dispatcherREQUEST/dispatcher from your filter config in the web.xml and the filter will be invoked for RequestDispatcher.forward(..), because it was not invoked for the original request. I know this does not solve your problem, but I think there is maybe a workaround for this.. I myself just don't know one.. Maybe define the filter twice would solve the problem, but that's just a guess.

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards
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.

Hi Tomasz,
That's all correct! However, I don't think he is using Facelets, because he
mentioned JSP-pages...

Hi,
as I understand you use a commandButton and as a result a different page (a
secured one) is rendered but spring security does not seem to intercept the
url, is that right?
If so and if the solution used by you uses Facelets then this may be the
problem.
When using Facelets as opposed to pure (older) jsf+jsp approach there is
no forward when a new view is rendered that is a result of a navigation case
forward. I've been investigating this recently. When JSP view handler is
used it checks which view should be rendered next and does a forward to this
new view which spring security can intercept. The Facelet view handler
however seems to load the view (xhtml) and render it without making the
actual forward. As a result no interception can happen and usually it is
triggered with the next request.
You need to either use redirects or make GET requests to logically separate
views - I know this is not natural with jsf versions prior to 2.0, but this
new spec seems to change everything :-) - use can easily generate GET
requests with the new version.
Hope this helps ;)

Tom Pasierb

RE: Spring FilterSecurityInterceptor not been called for myfaces forwards
Thanks for your response Jakob. What you have mentioned is already known to me. That is the reason I have put a dispatcherFORWARD/dispatcher 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 jsp:forward. 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.

So if you are on index.jsp and hit for example a h:commandLink, you will get a request for index.jsp. However, after the action method on the server is finished, the server renders the new view, depending on the outcome of the action method, in your case login.jsp. But your browser still displays index.jsp in the address bar, because that was the page you requested. When you add redirect / in the faces-config, JSF will instead of just rendering the new view, redirect to it. Thus you have a second http round trip and your browser's address bar will display the new view. I hope this explains things.

RE: Performance issues with JSF
Shashi wrote: Hi All - We have built a J2EE application with JSF (MyFaces, Ajax4JSF) ,Spring and IBatis. What we find is, each of the screen takes lot of time to load. We find no performance issue with Spring or Ibatis (after verifying via JProfiler). Jprofiler shows the JVM memory is occupied b JSF objects. I found that the screen loading is taking time for two reasons. 1.The JSF screens (which has cook menu) take time to load. 2.The overall screen painting in the browser takes time to load. Our JSF screens are not too complicated and even the simplest screen takes time to load. Note that each of the screens always loads JSCookMenu. We visited apache site for tuning JSF. As per their suggestion we did the following 1. We set the State saving mechanism as server side. 2. Serialization of session objects was set to false. 3. Compression of objects was set to false. 4. Streaming Add Resource and t:documentHead were added. But none of these improved the performance. The overall screen takes time and I'm wondering if we should do effective caching of images,CSS and js files. I visited plenty of websites and tried to move all these client specific files under the head tag, loaded the images via CSS but nothing helps. We have high capacity machines and I dont think desktop config is playing a role. We thought the problem could be bcos of network traffic or slow performance of underlying platform websphere server. We checked other application running in the same envrironment and they are extremely fast. The only difference b/n our application and the other is JSF. I'm short of solutions. Any valuable input will be greatly appreciated. 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. Thanks, Madhav

Feature to disable/enable components using JS
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:
t:inputText id=someID value=#{someBean.someValue}
disabled=#{jsFunctionToDisable()}/
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.

The spec is clear that a ValueChangeEvent should only occur if
validation passes. I've got a copy of the JSF2.0 early draft handy, and
in section 3.2.6.3:
quote
EditableValueHolder is a source of ValueChangeEvent events, which are
emitted when the validate() processing of the Process Validations phase
of the request processing lifecycle determines that the previous value
of this component differs from the current value, and all validation
checks have passed (i.e. the valid property of this component is still
true).
/quote
However before you report a bug, please check whether this still happens
in a plain MyFaces environment. I see you are using tomahawk + sandbox +
a4j all together here, which is a complex combination.
And when you have questions, you should always specify what version of
MyFaces and what version of Java you are using. Neither of those
critical pieces of information are in your original email.

Apologies for not mentioning the JSF version. Here are the details:
Sun JSF RI 1.1_02
Tomahawk 1.1.7
Tomahawk-sandbox 1.1.7
Richfaces - 3.1.6
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.

Check if anything has been changed on the form
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 CAUTION - Disclaimer * This e-mail contains PRIVILEGED AND CONFIDENTIAL INFORMATION intended solely for the use of the addressee(s).

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.

You will not be able to use faceContext.messages because messages is not a

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?

RE: Using Ajax with MyFaces
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.

How to get hold of the event queue in JSF?
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:
t:selectOneMenu id=provTypCd style=width:163
value=#{durMaintenanceController.provTypCd}
f:selectItems id=selitms1
value=#{durMaintenanceController.providerList}/f:selectItems
a4j:support event=onchange
actionListener=#{durMaintenanceController.fetchRtsMdl}
reRender=rtsMdlkey,percentageVal,descrptn,texterlMdsLmt1,Limit1,texterlMdsLmt2,Limit2-AboveLimit1,
texterlMdsLmt3,Limit3-AboveLimit2,texterlMdsLmt4,Limit4-AboveLimit3,texterlMdsLmt5,Limit5-AboveLimit4,
texterlMdsLmt6,Limit6-AboveLimit5,texterlMinPctAbv6/a4j:support
/t:selectOneMenu
t:selectOneMenu id=rtsMdlkey style=width:163
value=#{durMaintenanceController.strdMdlKey}
f:selectItems id=selitms21
value=#{durMaintenanceController.earlyRefillAppliesList}/f:selectItems
a4j:support event=onchange
actionListener=#{durMaintenanceController.fetchEarlyRefillValues}
reRender=percentageVal,descrptn,texterlMdsLmt1,Limit1,texterlMdsLmt2,Limit2-AboveLimit1,
texterlMdsLmt3,Limit3-AboveLimit2,texterlMdsLmt4,Limit4-AboveLimit3,texterlMdsLmt5,Limit5-AboveLimit4,
texterlMdsLmt6,Limit6-AboveLimit5,texterlMinPctAbv6
/a4j:support
/t:selectOneMenu
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)
t:inputText id=percentageVal size=23 align=left
forceId=true
value=#{durMaintenanceController.lkupPercentage}
maxlength=5
f:converter
converterId=com.wellpoint.benefitbuilder.NullConverter /
custom:requiredValidator /
custom:validateDoubleRange minimum=0 maximum=100 /
/t:inputText
t:inputText id=descrptn size=23 align=left maxlength=100
forceId=true value=#{durMaintenanceController.description}
f:converter
converterId=com.wellpoint.benefitbuilder.NullConverter /
custom:requiredValidator /
/t:inputText
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 s:subForm 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
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?

RE: Attach the current JSF View as an attachment
Matt wrote : Hi Madhav, This is an interesting requirement. Off the top of my head I'd say you could probably make a custom component to wrap the section you want to capture. Then in that components renderer, in the encodeBegin method you switch the responseWriter to a StringWriter or some other writer. Then in encodeEnd you save the contents of the StringWriter somewhere you can use it later and set back the correct responseWriter, and if you still want to write the response you can do so. Also you need to override rendersChildren and have it return true. The code would look something like this. private ResponseWriter oldWriter; private StringWriter sWriter; // encodeBegin sWriter = new StringWriter(); HtmlResponseWriterImpl writer = new HtmlResponseWriterImpl(sWriter, text/html,utf-8); oldWriter = context.getResponseWriter(); context.setResponseWriter(writer); //encodeEnd StringBuffer sb = sWriter.getBuffer(); // do what you want with the sb context.setResponseWriter(oldWriter); // if you want to output it as well... oldWriter.write(sb.toString()); I think this may work for what you want to do. Matt 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.

t:inputCalendar component converter problems
Hi All, I wanted to decorate the default converter that comes along with HtmlCalendarRenderer class for t:inputCalendar 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?

RE: Displaying messages over the content - generated by the content?
felix.bec...@t-systems.com schrieb:
Hi,
I've got a JSF page divided in 2 parts - the status message area and
the content area. The content area is positioned under the status
message area. In the status area all messages for the user should be
shown - for example success messages, error messages and exceptions.
In my content area I've got a tr:dataTable
value=#{myBean.values}... When the method getValues() of myBean
throws an exception, I'm catching this exception. I want to display
this exception in the status message area - but this does not work -
apparently because the status area is already rendered when the
content el-methods are called. Is there any solution for this problem?
Is it possible to render the status area at last?
I can't think of an easy solution for this.
Output generated during rendering is (at least theoretically) sent over
the network to the remote browser as it is created. So as you point out,
your status area has already been written before you encounter the
exception. There is no TCP feature to unsend data.
One obvious option would be to move your status area to the bottom of
the page.
Or you could write out the status area at the bottom of the page, then
use CSS positioning rules to make it *appear* at the top of the page. Or
use javascript to move the generated messages block from the bottom of
the page to the top.
Note that JSF messages created during:
* conversion
* validation
* action-handling
are no problem. It is only exceptions during rendering that would be an
issue. I can't think why you would be getting errors during fetching of
rendered data; I've not had to deal with that before except when wanting
to display some kind of result set too large message. Maybe you can
move the fetching of this data up into the action method of your bean?
Regards,
Simon
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.

FacesMessage objects are attached to the FacesContext, not the view. And
a FacesContext is a request-scoped object. So AFAIK, a second request
will always see an empty messages list...
Regards,

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.

t:messages component's strange behavior when used with Tiles and Sun JSF
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:
t:messages/t:messages
t:inputText id=descrptn size=23 align=left maxlength=100
required=true forceId=true
value=#{durMaintenanceController.description}
/t:inputText
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
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:
select id=form:listValue_AVAILABLE name=form:listValue_AVAILABLE
multiple=true size=10
ondblclick=A4J.AJAX.Submit('_viewRoot','form',event,{'parameters':{'form:a4jDesc':'form:a4jDesc'}
,'actionUrl':'/BenefitBuilder/web/jsp/supervisor/drugListMaintenanceScreen.jsf'}
) style=width=25pc option value=9Fertility Drugs/option
.
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

RE: Can tomahawk be used without myfaces
Hi Pawel, What was the version of tomahawk and Sun RI libraries that you used? Thanks, M Hi, Although I'm not able to help you with websphere deployment, I can assure you that generally speaking, YES, it is possible to run Tomahawk without Myfaces implementation of JSF. In our projects we were forced to switch to RI implementation due to buggy myfaces libraries, but we didn't want to drop Tomahawk extensions and we went successful. The difference is, that we use Tomcat 6.x instead of websphere.

Re: Running into NullPointerException when running Myfaces + tiles on WebSphere 6.0
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 On Wed, Nov 19, 2008 at 9:15 PM, jhomuth [EMAIL PROTECTED]wrote: Hi Madhav, I don't know if I understand you wrong or you have make a mistake by reading the guide.

Re: Dependency Injection in Validators
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.

tomahawk inputFileUpload component times out for large files
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.

Hi All, We have a label and an input text next to it. Place the cursor on the input text and now move the mouse over the label. The popup showing the tooltip comes up. The problem is that on IE the blinking cursor is still shown on the tooptip. I did try and dig out if there was a JIRA raised and i found this: http://www.mail-archive.com/[EMAIL PROTECTED]/msg09075.html According to it was marked as closed. Ideally the fix should be present in tomahawk 1.1.5 and myfaces 1.1.5 which i am using at present. Please let me know if this defect is being again worked upon.

Hi All,
We have a label and an input text next to it. Place the cursor on the
input text and now move the mouse over the label. The popup showing the
tooltip comes up.
The problem is that on IE the blinking cursor is still shown on the
tooptip. I did try and dig out if there was a JIRA raised and i found this:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg09075.html
According to it was marked as closed. Ideally the fix should be present in
tomahawk 1.1.5 and myfaces 1.1.5 which i am using at present.
Please let me know if this defect is being again worked upon.
Thanks,

disable input text box generated from t:inputFileUpload
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.

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. Thanks, Madhav From: Andrew Robinson [mailto:[EMAIL PROTECTED] Sent: Fri 7/20/2007 6:41 AM To: MyFaces Discussion Subject: Re: disable input text box generated from t:inputFileUpload 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.

I just cannot make InputSuggestAjax component work
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:
s:inputSuggestAjax suggestedItemsMethod=#{ajaxsuggest.suggest}
itemLabelMethod=#{ajaxsuggest.getLabel} value=#{
ajaxsuggest.selectedBean}
f:converter converterId=inputSuggestAjaxConverter/
/s:inputSuggestAjax
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

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

Re: not displaying icon in t:navigationMenuItem
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.

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

A litle Help - building myfaces in eclipse using maven

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

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.

Madhav,
Well, people here seem to be quite sure that the
t:updateActionListener
is correct; I certainly don't *see* any problems with it, nor do I
*experience* any problems.
If you are going to say It should not be a problem with getter and
setter then I'm not sure that this list can be much more help. Looks
like you'll have to step through the updateActionListener with a
debugger - or build your own custom version with extra logging in it.

It should not be a problem with getter and setter as literal String

Sorry I didn't read the whole mail.
How exactly is msg defined?
I don't see here what version of Tomahawk you are working with. For
version 1.1.3 (which is what I have at hand) the value is fetched
just
using a standard call to getValue(), so there's nothing special
there.
However afterwards it tries to do some type-conversion:
Object v = getValue();
if (v != null
v instanceof String)
{
Class type = updateBinding.getType(context);
}
updateBinding.setValue(context, v);
If expression breadCrumbNavigatorBean.displayText doesn't reference
a
String property then there might be a conversion problem. Note that
exactly what defines a javabean property is slightly more complex
than
just having a setter method. For example, the setter must not be
static,
and there must not be a getter method with a conflicting signature.
You
could check by using java.bean.Introspector on this class and
verify
that it does agree that there is indeed a writeable String property
displayText. Ok, it's not likely that this is wrong but
t:updateActionListener is in wide use and there are no known
problems
with it so something odd is going on..

Simon

with my EL expression. But then when I used t:outputLabel tag
with
the

This means that there is nothing wrong with the EL expression. The

Ok, I looked at the LoadBundleTag class, and there is a nice comment
at
the start :-)
/**

This code is the same in Tomahawk 1.1.3 and trunk:
http://svn.apache.org/repos/asf/myfaces/core/trunk/impl/src/main/java/or
g/
apache/myfaces/taglib/core/LoadBundleTag.java
So there's the explanation. The f:loadBundle tag doesn't do anything
until the render phase, ie #{msg} is not valid during previous phases.
However the t:updateActionListener obviously must evaluate its
expression at update-model phase, so the message bundle has not yet
been
loaded.
As the comment says, what is really needed is for the f:loadBundle tag
to attach the name(s) of resource bundles to be loaded to the
component
tree (eg as attributes in UIViewRoot) and for these to be loaded
during
restore-view phase.

Madhav Bhargava wrote:
I guess I know what the problem is.
The EL expression that I have used is:
#{msg['breadcrumb.label.reminders']}
This expression refers to a key (breadcrumb.label.reminders) in the
message bundle(Messages.properties)
When this value goes to the updateActionListener tag's doStartTag
method
it tries to create a ValueBinding out of this EL expression. This is
where it returns null as the value binding cannot be created.
To circumvent this problem in the setter method for displayText I
added
the following:
...
...
ResourceBundle bundle = ResourceBundle.getBundle(resourceBundleName,
locale, getCurrentClassLoader(params));
this.displayText= Bundle.getString(key);
In the JSP I pass:
t:updateActionListener
property=#{breadCrumbNavigatorBean.displayText}
value=breadcrumb.label.reminders/
*Now it works!!*
I guess you cannot pass a EL that references a message bundle as a
value
for t:updateActionListener.
The only thing that I cannot understand is -
I have f:loadBundle basename=com.bingo.tringo.bundle.Messages
var=msg/ in the Jsp.
The same EL expression works when given as a value to
t:outputLabel
component but then it does not work when given as a value to
t:updateActionListener
If someone can throw some light then that will be great.

RE: how do you pass/set parameters upon ActionListener execution?
Hi Werner,
Yes, you are right. But I still cannot get the values in my backing
bean.
Jsp code:
t:commandLink value=Add Reminders styleClass=linkClass
action=#{reminderController.showAddReminderScreen}
actionListener=#{breadCrumbNavigatorBean.updateBreadCrumb}
rendered=#{!physicianHomeController.showRemindersMoreLink}
t:updateActionListener
property=#{breadCrumbNavigatorBean.participant.displayText}
value=#{msg['nav.msg.remiders']}/
/t:commandLink
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?

Madhav

Subject: Re: how do you pass/set parameters upon ActionListener

This is not quite true, the updateActionListener
sets the parameters bevore the invocation of the action
this is due to jfs lifecycle where the apply request values
is before the action, which phase depends on your immediate value:
I quote the original docs here:
Both the fetching of value and the updating of property occur in
the invoke-application phase unless immediate is set on the
ActionSource component in which case they both occur in the
apply-request-values phase. The update is guaranteed to occur before
the invocation of the method specified by attribute action on the
ActionSource (because all actionListeners are executed before the
action attribute).
so you basically already have the params available before you go into
the action.
so you do not have params per se in an action but you can push params
into your bean bevore invoking the action.

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

Sorry I didn't read the whole mail.
How exactly is msg defined?
I don't see here what version of Tomahawk you are working with. For
version 1.1.3 (which is what I have at hand) the value is fetched just
using a standard call to getValue(), so there's nothing special
there.
However afterwards it tries to do some type-conversion:
Object v = getValue();
if (v != null
v instanceof String)
{
Class type = updateBinding.getType(context);
}
updateBinding.setValue(context, v);
If expression breadCrumbNavigatorBean.displayText doesn't reference a
String property then there might be a conversion problem. Note that
exactly what defines a javabean property is slightly more complex
than
just having a setter method. For example, the setter must not be
static,
and there must not be a getter method with a conflicting signature.
You
could check by using java.bean.Introspector on this class and verify
that it does agree that there is indeed a writeable String property
displayText. Ok, it's not likely that this is wrong but
t:updateActionListener is in wide use and there are no known problems
with it so something odd is going on..
Cheers,
Simon

t:commandNavigation2 activeOnViewId attribute does not work as described in an earlier thread
Hi All, I have left navigation menu (t:panelNavigation2 and embedded t:commandNavigation2 components) and a breadcrumb component. To keep both in synch I added activeOnViewId to the t:commandNavigation2 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?

Re: how does UICommand execute the action binding?
Thanks Mike,
So what i understand is that if only from-action 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:
navigation-rule
from-view-id/bingo.jsp/from-view-id
navigation-case
from-action#{sombean.someAction}/from-action
to-view-id/tringo.jsp/to-view-id
/navigation-case
/navigation-rule
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:
navigation-rule
from-view-id/bingo.jsp/from-view-id
navigation-case
from-action#{sombean.someAction}/from-action
from-outcomesuccess/from-outcome
to-view-id/tringo.jsp/to-view-id
/navigation-case
/navigation-rule
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 from-outcome, why is the
combination of both the tags is required?
Consider a third case:
navigation-rule
from-view-id/bingo.jsp/from-view-id
navigation-case
from-action#{sombean.someAction}/from-action
to-view-id/tringo.jsp/to-view-id
/navigation-case
navigation-case
from-outcomesuccess/from-action
to-view-id/tringo123.jsp/to-view-id
/navigation-case
/navigation-rule
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?

I am not sure which version of tomahawk are you using?
Check out the TLD documentation at:

You will find actionFor attribute as part of both t:commandLink and

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 from-action 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 from-outcome as it is finally going to go to the outcome
produced by the action method.
Could you please throw some more light on from-action usage?
Rgds,
Madhav

Simon,
I don't have any JSF books handy. What's the difference between
from-action and from-outcome? I thought outcome was the string
returned from an action method?
You can use either or both.
* from-action describes the EL expression that triggered
calling your action. This is useful if you have multiple buttons
on the form, bound to different actions. (It's also legal to
have more than one command component bound to the same
action method ... for example, a next page or previous page
link at both the top and bottom of a long page.
* from-outcome describes the logical outcome returned by
whatever action was invoked. This is useful if you want to
go different places depending on what happened inside an action.
If you use just from-action, your navigation rule is triggered
whenever that action is executed, no matter what outcome was returned.
If you use just from-outcome, your navigation rule is triggered
when that outcome is returned by any action that was processed. Or,
you can use them together to define more precisely when this
navigation should be triggered.

Yep. The from-action value is meant to match the string *returned*
from
an action method. It is not an EL expression.
I suggest you find a good JSF book and read the section on
navigation.

Re: stateChangeNotifier does not work with t:commandButton properly
Hi Nako,
Thanks for the pointer.
I have to use a command button.
Is there anyway (apart from styling the command link as a button) to check
if there is a change in the form when the user tries to go some where else?
Thanks,

In the encodeJavascript method following line is present:

This will add a timeout of 500. However this setting does not have any
effect on command links. Moreover should not this value be configurable? If
someone does not want a timeout, rather wants to use to necessary choose
before moving ahead then he/she will not be able to do it.

*Subject:* stateChangeNotifier does not work with t:commandButton
properly
Hi All,
I have been looking for a component like s:stateChangeNotifier for quite
some time and I am glad that it is there is sandbox finally.
The problem with this component is that it does not work properly with
t:commandButton component.
Consider the following code:
s:stateChangedNotifier
confirmationMessage=There are changes in the form. You will
loose all data if you choose to leave the form. Do you want to cancel?
excludedIds=_patientRegistration_proceed,
_patientRegistration_reset disabled=false/
And then you have the following buttons:
t:commandButton id=_patientRegistration_proceed forceId=true
value=Proceed action=#{patientRegistrationWizardBean.proceed}
actionFor=patientRegistration/
t:commandButton id=_patientRegistration_reset forceId=true
value=#{msg['button.demographicdetails.reset']} action=#{
patientRegistrationWizardBean.reset}/
t:commandButton id=_patientRegistration_cancel forceId=true
value=Cancel action=#{patientRegistrationWizardBean.cancel}/
Now the problem is that when I click the Cancel button then the popup
only appears for 2 seconds and then it vanishes and the control goes to the
action method attached with the command button.
However, this problem is not there with the command link. I have
something like:
t:commandLink id=_patientRegistration_dummy forceId=true
value=dummy/
Now if I click this link then the modal popup stays there till you click
a link.
I have following questions:
1. Does this component only work with t:commandLink component?
2. If I have a datagrid and one of the columns in the datagrid is a link
View Details. Say if there are 20 rows displayed in one page and there are
other command buttons on the page to control navigation. Then will I have to
put all the ID's for all the links in the column to prevent the popup
appearing on click of any of the View Details link?
Rgds,
Madhav

valueChangeListener does not work in s:subForm component
Hi All,
I have a form which has a subForm for partial submits and validation.
This sub form has a drop down, following is the code:
x--- Cut ---x
s:subForm id=test
.
.
.
t:selectOneMenu id=selSites onchange=submit()
valueChangeListener=#{appointmentSchedulingWizardBean.detailsChanged}
value=#{appointmentSchedulingWizardBean.wizard.schedulingDetailsCapture
State.site} required=true
f:selectItem itemLabel=-Select- itemValue= /
f:selectItems
value=#{appointmentSchedulingWizardBean.wizard.siteList} /
/t:selectOneMenu
.
.
.
/s:subForm
x--- Cut ---x
Problem:
Value Change listener for the drop down does not get called. There is a
slight flicker on the page which suggests that the form is submitted but
I guess none of the values in the subForm are submitted due to which the
value change listener is also not called.
However if we take this piece of code for the drop down and put it out
of a sub form then it will call the value change listener for the
component.
How do you invoke the value change listener in case of a component
inside a subForm?
