[TRINIDAD] - Strange behaviour with NumberConverter
Hi, I'm facing a strange issue with NumberConverter on the client side in Apache Trinidad. On one side, using my local dev machine, everything works as expected; i.e. all the values entered by the user are converted to number/currency depending on how they're configured (for example, let's say it's currency, so the user enters 12 in the text box and it gets converted to 12,00 €). However, I just deployed the WAR file to a remote server and the behavior is really weird: when the user enters something in the same text boxes, let's say 12, the following messages appears: Cannot convert 12 of type class java.math.BigDecimal to class java.lang.Number As explained, both environments are similar (same JDK 1.6, same Tomcat, same WAR file), but locally is working fine and remotely looks like not. Even more funny is the fact that although you get the error message, the value is finally converted to currency, for example, so in the text box I end up having the proper converted value -- 12,00 € Anyone has a clue on what could be happening here? Apparently it's only working for me locally using my MacBook Pro with JDK 1.6 and Tomcat 6.0.x. BTW, this is Apache Trinidad 1.2.10. Thanks.
Re: [TRINIDAD] - Change tab in panelTabbed using a button
Thanks Matt, but finally I went the easy way using JS:
tr:commandButton text=Next
partialSubmit=true
onclick=document.getElementById('tab2').onclick()/

I imagine that your Java code will look something like this (do this
for each showDetailItem in the panelTabbed):
FacesBean facesBean = showDetailItem.getFacesBean();
FacesBean.Type type = facesBean.getType();
PropertyKey disclosedKey = type.findKey(disclosed);
if (disclosedKey != null)
{
facesBean.setProperty(disclosedKey, newDisclosedState);

MyFaces and Axis

Re: Need to use Spring
Hi,I totally agree with Fintan. The question would be whether to use frameworks on top of JSF, rather than be worried about the business part of your application. Remember JSF is a presentation MVC framework, so it can be used in conjunction with ANY business solution (call it Spring, Hibernate, JDO, JPA, EJBs, etc.). Regarding those complementary frameworks for JSF, take a look at Shale, Facelets, ADF Components, security issues like Acegi (requires Spring), etc ;-)Hope it helps.Regards,Enrique Medina.

I'm asking because we had some problems with session-per-conversation concerning objects that did not have clear conversation boundaries. I cannot clearly say, but to my knowlege you can have multiple conversations. The shopping cart szenario is somewhat different, because this is clearly a case for a session scope and not a limited conversation. So with a shopping cart you are better of with a session.merge instead of keeping the db session open. I only can talk as an outsider here, since I do not have any affiliation with Seam or the jboss guys. the way I see it the opensession in conversation is more suitable for szenarios where you load a set of objects and then do something within the same form or 1-2 subsequent forms, the typical crud szenario. That way you can gain the comfort of statefulness and not having objects out of a session during the lifetime of your use case. But I do not see any reason to have that in a shopping cart, because keeping a session open during the lifetime of a user session is a drain on resources. If you want to do that you do not have to use Seam or a dialog system simply keep an open session in your servlet session and use that one for all db access related stuff. But there is a reason why this approach is not used that often.__Do You Yahoo!?Tired of spam?Yahoo! Mail has the best spam protection around http://mail.yahoo.com

started. What we do now is load our data in controllers, then set the
data
in the BB manually.
Good
luck.

ExceptionHandling with JSF and Tiles
Thanks for your
answer.
I tried this and your
points 1) and 2) are working well.
But I can't get jsp
errors redirected to the error jsp.
The
ErrorHandlerServlet is called but the content of my error jsp is not displayed
in this case.
The tiles are still
partially rendered and the previous ServletException (s. mail below) is not
displayed anymore.
Where did you define
the errorPage directive ?
In the outer tiles
layout template or in the various included tiles definitions (e.g. in all
content jsps)?
Hmm, I tried both and
it is not working.
Thanks for your
help

We had the same
problem with exceptions inBB constructors...Our solution was not pretty,
but here it is:
Yes, the new page was
always partially rendered before we could catch the error in time. The
suggestions
I got from the forum
was to simply set the flush directive to false in tiles...but it never worked
properly.
1) We created a
servlet which simply redirects to a JSP error
page.
2) From an error in
aBB contructor error - we mapped it to the servlet via
web.xml
3) From a jsp parsing
error - we used the errorPage directive and mapped it to the same
servlet.
%@page errorPage=
/error/ErrorHandlerServlet %
An alternative
solution is to use a controller and have the controller execute the code which
might generate an exception.
(This is what we have
decided to do for the future.)
We are also
interested in alternative solutions.

MyFaces DiscussionSubject: ExceptionHandling with JSF and
Tiles
Hi
all,
I am still confused about
Exception Handling. I know that this has been discussed on many threads but
I don't know how to handle exceptions
outside Actions/ActionListeners.
My setup is MyFaces 1.1.1 and
Tiles with the JspTilesViewHandlerImpl.
I can create FacesMessages and
forward to any outcome page when an exception occurs in an
action/actionListener. This is working fine and no
problem.
I don't know how to handle
serious errors in BackingBean constructors or
setters.
I tried to catch them and
re-throw them as FacesExceptions but my error pages (defined in web.xml) are
not displayed.
Instead of the error page the
original requested tiles template is partly
processed.
A ServletException is displayed
in place of the tiles-part that caused the
error.
e.g. ServletException
in:/xxx.jsp] Cannot get value for _expression_
'#{ABackingBean.aValue}'
How do others handle exceptions
with myFaces and Tiles?
Are there any best
practices?
Any help would be greatly
appreciated.

Re: ajax form
Hi,I'm currently using Ajaxanywhere in my applications, and it's pretty cool. However, the nature of JSF doesn't allow me to use it when the portion to be ajax-refreshed is from a different URL.

Sebastien,Note that you will also have to deal with lazy loading (if you use it) for references or collections of references. This is easier as you only have to call session.lock(object, LockMode.NONE).This is a compulsory dependency when working with Hibernate lazy loading, due to the way it handles its own sessions (so you end by never having a completely independent presentation layer, as ideal architectures claim).

Re: MYFACES-703 (Have to manually specify renderer type for ExtendedDataTable)
Well, I was unhappy for the frustrating situation of upgrading to a new release, and see how my application was not working anymore. Then I realized that a bug about this problem had been commented in the JIRA list, and simply warned about this issue.
In other words: if the bug was detected after the release of version 1.1.1, then it is a bug and, as you comment, it has been solved. If the bug was detected prior to the release of version 1.1.1 and was not solved, then my warn was about this issue. I recognize I didn't have time to see whether the bug was prior or after to the release...
Anyway, my message was not to shout about my problem, because I know that bugs have to exist, and I know how to find them and provide a patch to solve them, but to emphatize the fact of being careful with regression problems when releasing new versions (if and only if the bug was prior to the release).

} So if you use the ExtendedDataTable through the HtmlDataTableTag, you will get: public String getRendererType() { return org.apache.myfaces.Table

1.1.1. Regards, Enrique Medina. 2006/2/26, Martin Marinschek [EMAIL PROTECTED]: Hi Enrique,

substituteSubmitButtonsBehavior. So other buttons would stay
For all2.jsf from the DEMO application it
would look like this :
ajaxAnywhere.substituteSubmitButtonsBehavior(true,[ajaxAnywhere.findForm().elements['mainForm:selectBoxBtn']]);
then, if you add a second command button
h:commandButton
action="" value=Calc No AJAX id=selectBoxBtn_nonAJAX
/
it would work without Ajax.
some doc is available here
http://ajaxanywhere.sourceforge.net/js_docs_out/AjaxAnywhere.html#substituteSubmitButtonsBehavior
Vitaliy.
PS. Indeed, there are several bugs discovered
here and I need to fix them. It should work when returning null from
getZonesToRefresh(), next release will fix it.
PPS. for the navigation to another page when
submitting with AA, did you try redirect parameter in JSF config? I'm not
sure but it should work, as response.sendRedirect() is interpreted as
location.href="" on the client side.

Re: Ajaxanywhere
And more testing...I have downloaded the DEMO from
the Ajaxanywhere site, and made a change on the facesFrame.jsp to make the
Calculate price button non-ajaxed. And it does not work; i.e. if I quit
the Calculate price from the ajaxed zones, then the action is never
executed. From my experience, Ajaxanywhere does not work with a
page combining ajaxed and non-ajaxed JSF actions.

Definetively,
I can't make it work. I've created a simple JSF page with two buttons:
one is a save for the form and the other just navigates to another page
(simulating a cancel action). The save button works great, but when I
press the cancel/exit button, then nothing happens. I've been
also doing some debugging, and when using Ajaxanywhere, the submit of
the non-ajaxed button does not update the parameterRequestMap used after
to decide whether it is an immediate request, etc.No idea of
what I'm doing wrong Emmanuel can you please help? Can you
provide some of your JSF pages? What version are you using? Are you
working with buttons?Thanks.

the common JSF button works, and obviously my ajaxed zone is ignored
and the page is completely refresehd; if I add it again, then the

It's clear the problem comes with the JS and how does
Ajaxanywhere handle the request...

again,I have tried the solution you prop
Re: Ajaxanywhere
Finally I solved all my problems ;-)Thinks to take into account:1) Return null should work (see the thread) -- For me it wasn't working due to a side-effect problem. If it doesn't then use an array to define buttons that must be ajaxed (see thread) 2) VERY IMPORTANT -- Define the AAFilter as being the first filter in your chain -- This was the cause of all my problems with NULL pointer exception -- At least it MUST be the first one when another ServletResponse wrapper is in the game (as was happening with the ExtensionsFilter response wrapper) 3) If you're using Firefox, download the script debugger to see what's happening with JS behind the scenes ;-) You will find lots of interesting stuff, like preprocessors to the Ajax request, for example ;-)4) Don't use redirect in the navigation rules, or the Ajax request will be simply bypassed Hope it helps to clarify the use of Ajaxanywhere with Myfaces.Thanks to anyone that has given me any kind of support with this issue, and thanks very much to guys like Vitaliy for giving us tools like this fantastic Ajaxanywhere :-) 2006/2/23, Enrique Medina [EMAIL PROTECTED]: Sorry, you were right...I've tried it and it works great, but there are some cases where I get a NullPointerException when clicking the ajaxed button. But then I click it again, and it works!!! Debugging through your code, I see that when the cause why the exception is thrown is due to a call to the internal writer object of your BufferedResponseWrapper class, which is null. But it is not null for the second request on the same button... I'm missing something... By the way, using your proposal, should I continue using the ajaxAnywhere.getZonesToReload? Thanks very much for your support ;-)2006/2/23, Vitaliy Shevchuk [EMAIL PROTECTED]: it IS the other way round ;) read carefuly my message ajaxAnywhere.substituteSubmitButtonsBehavior(true,[ajaxAnywhere.findForm().elements['mainForm:selectBoxBtn']]); // -- arrays of ajaxed buttons - Original Message - From: Enrique Medina To: Vitaliy Shevchuk Cc: MyFaces Discussion ; [EMAIL PROTECTED] ; [EMAIL PROTECTED] ; [EMAIL PROTECTED] ; [EMAIL PROTECTED] ; [EMAIL PROTECTED] Sent: Thursday, February 23, 2006 8:38 AM Subject: Re: Ajaxanywhere Hi Vitaliy,Then you mean that buttons that are not Ajaxed must be passed as argument to the substituteSubmitButtonsBehaviour?

No I am working mostly with commandLink and it works fine, i.e. combining ajaxed and non ajaxed actions is fine for me. Have you tried your test case with a link rather than a button (that might be a good test to make sure it is not an issue), are you sure that your js picks up the correct button id,
i.e that the correct zones are returned. Looks to me that the id might be wrong, try to add some js alert to make sure that the correct zones are returned (or null if the AA filter should be bypassed).

Hi,Has anyone successfully used Ajaxanywhere inside a JSF page with a piece of the page being ajaxed and the other piece not? Let me give an example: imagine a JSF page where the selection of a combo box must force the refresh of another combo box. This zone is ajaxed using aa:zoneJSF. But buttons to save or go to another page in the navigation are not ajaxed.
My problem is that the ajaxed zone works great, but then I have a button to save, and another one to navigate to another page, and those buttons don't seem to work. When I click them a request is sended, but none of their respective actions are executed, no error messages are shown (I have a global tag in the page). It seems like a request with an action returning simply null (not doing anything).
My _javascript_ for Ajaxanywhere looks like this:
ajaxAnywhere.getZonesToReload = function(url,submitButton) { if (submitButton.id.equals('myAjaxButton') return dataZone;

Dynamic multiple selection list with Javascript breaks JSF
Hi,I'm trying to do a simple multiple selection list where the user can add String values. The operation for adding these values is through a simple _javascript_ method, using the new Option mechanism.However, when the form is submitted, I always get a Validation error. Going through the code, I see that at some point the component expects the value to be a SelectItem object, but obviously it isn't, as it has been added dynamically using _javascript_. I was wondering whether this is the correct bahaviour or I am missing something, because I can't make a simple selection list work :-(Regards,Enrique Medina.
Re: Dynamic multiple selection list with Javascript breaks JSF
Hi Emily,You're right. Obviously the better way to accomplish it would be to make a request on each addition, in order to update the SelectItems list for the component. I'm going to try this, but with Ajaxanywhere, just to save the user from the page refresh each time she adds an item. Regards,Enrique Medina.2006/2/18, Emily Gu [EMAIL PROTECTED]: Since you have used _javascript_ to add options into the selection list, it only knows by the client not the server. You will have to put those added values in a hidden field, then getthem after the form submission instead of getting it from the selection list directly. That's one of workaround I used. I don't know whether there is any other way to do it.

Re: JSF+Hibernate
Ok. Then the problem is clear. As the pattern creates for you a new session in each request, the object you are trying to update is DETACHED, so unless you associate to a PERSISTENT instance in the current session, you will get the error. But as I can imagine this is not possible, you will have just to reattach the object to the current session, by using: session.lock(object, LockMode.NONE)in your backing bean.But I would suggest to make your backing bean session-scoped, and also to enable the second-level cache ;-) 2006/2/2, ::SammyRulez:: [EMAIL PROTECTED]: 1) yes2) request-scoped2006/2/2, Enrique Medina [EMAIL PROTECTED]: Some questions: 1) Do you use the Open Session in View filter pattern? 2) Is your backing bean request-scoped or session-scoped or application-scoped? 2006/2/2, ::SammyRulez:: [EMAIL PROTECTED]: Hi all I have a form for some data entry and a data table displaying the rows already entered in the same view.

Re: Dynamically refer to a component from another component
Hi Simon,Yes, that was exactly the point. It's as easy as adding all the children, and at the end of the tree component creation, call to getClientId().Thanks a lot for your support.
2006/1/19, Simon Kitching [EMAIL PROTECTED]:
I believe Volker's answer is exactly what you're looking for. UnlessI've misunderstood your question, method getClientId is what you want;you just need to make sure the component is attached to the view treebefore calling that method.
ie:UIOutput texto4 = createComponent(..);texto4.setId(texto4);// parent is expected to already be attached to the view tree.parent.getChildren().add(texto4);// do this only after adding to view tree. You'll then get the
// full final id of the component, eg form1:subview1:table3:texto4String texto4ClientId = texto4.getClientId(facesContext);// use texto4ClientId in _javascript_ emitted for some other component
If you need to find the texto4 client from some other renderer, youcan search for it:UIOutput text05 = createComponent(..);// find a component with the specified name within the same
// naming container as the component the find is invoked onUIOutput targetComponent = parent.findComponent(texto4);String targetClientId = targetComponent.getClientId();// use targetClientId in _javascript_ emitted for texto5 component
Note also that component ids starting with underscores are reserved forthe use of the JSF framework; any id you assign explicitly should *not*start with an underscore.Regards,Simon

[EMAIL PROTECTED]: Let me give a more detailed explanation of what I am trying to achieve..
In my application I need to work with data in a spreadsheet form, so I decided to use a PanelTabbed component, where each tab would contain a HtmlDataTable. All these would simulate an
Excel page, where I can change the actual tab, make some modifications to the elements in the table, go to another tab, modify, etc, so at the end
I would press the save button, and all the changes would be persisted to the DB. The big problem I had with defining this page was the
fact that all the data that was used to populate the tables in each tab was not known at compile time, as it depended on the values entered by the
user during the normal use of the application. So I had to create all the components dynamically through Java code. To accomplish this objective, I created a JSP file with
simply a PanelTabbed tag that I binded to a property in my backing bean, so whenever JSF called my setBindedTabbedPane method, I could create
all the tabs, tables, labels, inputs, etc, in code. Once done, everything was perfect, in the sense that my application was implemented to dynamically create all the components
needed to simulate an Excel worksheet; i.e. dynamic number of columns and rows, dynamic number of tabs, etc. On the other hand, I have also added DWR to my
application in order to use Ajax for particular purposes, like showing child data in a datatable, or simply validate some specific fields
without having to make a JSF request. So I decided to add a DWR Ajax validate process to my recently created Excel worksheet.
But the problem comes because when using DWR Ajax, I need to define a callback function in _javascript_ where I have to pass as a parameter the value that I want to be validated. As you
already know, I am generating all the components dynamically in code, within a loop that reuses temporal variable names for the sake of
performance and clearness. This means that I

ie:UIOutput texto4 = createComponent(..);texto4.setId(texto4);// parent is expected to already be attached to the view tree.parent.getChildren().add(texto4);// do this only after adding to view tree. You'll then get the
// full final id of the component, eg form1:subview1:table3:texto4String texto4ClientId = texto4.getClientId(facesContext);// use texto4ClientId in _javascript_ emitted for some other component
If you need to find the texto4 client from some other renderer, youcan search for it:UIOutput text05 = createComponent(..);// find a component with the specified name within the same
// naming container as the component the find is invoked onUIOutput targetComponent = parent.findComponent(texto4);String targetClientId = targetComponent.getClientId();// use targetClientId in _javascript_ emitted for texto5 component
Note also that component ids starting with underscores are reserved forthe use of the JSF framework; any id you assign explicitly should *not*start with an underscore.Regards,Simon

[EMAIL PROTECTED]: Let me give a more detailed explanation of what I am trying to achieve..
In my application I need to work with data in a spreadsheet form, so I decided to use a PanelTabbed component, where each tab would contain a HtmlDataTable. All these would simulate an
Excel page, where I can change the actual tab, make some modifications to the elements in the table, go to another tab, modify, etc, so at the end
I would press the save button, and all the changes would be persisted to the DB. The big problem I had with defining this page was the
fact that all the data that was used to populate the tables in each tab was not known at compile time, as it depended on the values entered by the
user during the normal use of the application. So I had to create all the components dynamically through Java code. To accomplish this objective, I created a JSP file with
simply a PanelTabbed tag that I binded to a property in my backing bean, so whenever JSF called my setBindedTabbedPane method, I could create
all the tabs, tables, labels, inputs, etc, in code. Once done, everything was perfect, in the sense that my application was implemented to dynamically create all the components
needed to simulate an Excel worksheet; i.e. dyna

Re: Dynamically refer to a component from another component
For those who might be interested...FInally I solved my problem. When the dataTable is being rendered, then it uses both the row number and the col number to generate the IDs, so I made use of the rowIndexVar and var properties of DataTable and UIColumns respectively to be able to access this information at runtime through EL. Then I created a simple _javascript_ function that replaced the ID I had at my code, with the extra information of rows and cols.
Works like a charmThanks very much again for those who have given me help and tips ;-)2006/1/20, Enrique Medina [EMAIL PROTECTED]

Re: unencode # encodings in javascript
Hi Mario,I have just implemented your workaround and it also works great for me.But shouldn't it be a more generic and straightforward mechanism to solve this problem? To the best of my knowledge, the problem is with the class HTMLEncoder, and particularly with this method:
public static String encode (String string,boolean encodeNewline,boolean encodeSubsequentBlanksToNbsp,boolean encodeNonLatin)
where this code is executed: default : if (((int)c) = 0x80) { //encode all non basic latin characters
app = # + ((int)c) + ;; } break;So my tildes in spanish are always encoded too.

don't know now) - however \u will be evaluated at parsing time, so youcant do something like alert(string.replace(#, \u)) nor \\u*) I have absolutely no clue why the \ stuff works, and here I had no
luck with it.So here is what I do now.There are only a handful places in our _javascript_ where we alertsomething to the user, I'll replace alert( by something like myAlert().In there, before passing the string to alert() I will convert the string
using the following simple script:/** * decodes all #nnn; in the given text to its corresponding character */function decodeHexEntity(text){var entitySearch = /#[0-9]+;/g;

On the other hand, I have also added DWR to my application in order to use Ajax for particular purposes, like showing child data in a datatable, or simply validate some specific fields without having to make a JSF request. So I decided to add a DWR Ajax validate process to my recently created Excel worksheet.
But the problem comes because when using DWR Ajax, I need to define a callback function in _javascript_ where I have to pass as a parameter the value that I want to be validated. As you already know, I am generating all the components dynamically in code, within a loop that reuses temporal variable names for the sake of performance and clearness. This means that I use the
FacesContext.getApplication().createComponent() to create every component, but reusing the same variable in the loop, as I don't know how many components will I have to create (i.e. how many inputs or datatables or tabs).
To better clarify, imagine that I want to add a _javascript_ call in the onclick method of an input text box. When creating the component dynamically, I could do: UIInput texto4 = (HtmlInputText)
FacesUtils.getApplication() .createComponent(HtmlInputText.COMPONENT_TYPE); texto4.getAttributes().put(styleClass, txt); texto4 .setValueBinding(

[EMAIL PROTECTED]: Let me give a more detailed explanation of what I am trying to achieve.. In my application I need to work with data in a spreadsheet form, so
I decided to use a PanelTabbed component, where each tab would contain a HtmlDataTable. All these would simulate an Excel page, where I can change the actual tab, make some modifications to the
elements in the table, go to another tab, modify, etc, so at the end I would press the save button, and all the changes would be persisted to the DB. The big problem I had with defining this page was the fact that all
the data that was used to populate the tables in each tab was not known at compile time, as it depended on the values entered by the user during the normal use of the application.
So I had to create all the components dynamically through Java code. To accomplish this objective, I created a JSP file with simply a PanelTabbed tag that I binded to a property in my backing bean, so
whenever JSF called my setBindedTabbedPane method, I could create all the tabs, tables, labels, inputs, etc, in code. Once done, everything was perfect, in the sense that my application
was implemented to dynamically create all the components needed to simulate an Excel worksheet; i.e. dynamic number of columns and rows, dynamic number of tabs, etc. On the other hand, I have also added DWR to my application in order
to use Ajax for particular purposes, like showing child data in a datatable, or simply validate some specific fields without having to make a JSF request. So I decided to add a DWR Ajax validate process
to my recently created Excel worksheet. But the problem comes because when using DWR Ajax, I need to define a callback function in _javascript_ where I have to pass as a parameter the value that I want to be validated. As you already
know, I am generating all the components dynamically in code, within a loop that reuses temporal variable names for the sake of performance and clearness. This means that I use the
FacesContext.getApplication().createComponent() to create every component, but reusing the same variable in the loop, as I don't know how many components will I have to create (i.e. how many inputs
or datatables or tabs). To better clarify, imagine that I want to add a _javascript_ call in the onclick method of an input text box. When creating the component dynamically, I could do:
UIInput texto4 = (HtmlInputText) FacesUtils.getApplication() .createComponent(HtmlInputText.COMPONENT_TYPE); texto4.getAttributes
().put(styleClass, txt); texto4 .setValueBinding( rendered, FacesUtils
.getValueBinding(#{puntuacionesBean.mapaScoreboardPuntuaciones[' + codigoGrupo + '].puntuacionColumna

.getValueBinding(#{puntuacionesBean.mapaScoreboardPuntuaciones[' + codigoGrupo +

texto4.setId(_input); Then this ID will be used as the last part of the HTML generated ID when rendering the page, so there is no way to know it when writing this code in the backing bean.
So in the end, my question was about how could I know that ID at runtime. I mean, I can use EL to bind values with my objects' properties, but could I also do something similar with component

Dynamically refer to a component from another component
Hi,I have a JSF page that is created dynamically in code. I want to use Ajax to validate that the value entered in some text box is correct, so for each input text component I create an HTML link that I want to refer to the value of the input text it refers to, so I can pass that value to the Ajax mechanism and validate it. Don't know if I have explained my problem well, but in the end, I would like to know if I can use EL to refer from one component to another, so in runtime one component can know the value of another one.Thanks.

Also take a look at: http://wiki.apache.org/myfaces/Working_With_DataTable_And_PreserveDataModel2005/11/22, Yee CN [EMAIL PROTECTED]: Hi, I noticed that if preserveDataModel=false, then JSF will attempt to fetch the table data twice – once during the apply request values phase, and once during the render response phase.

Re: HTTP re-post - another question.
Hi Jeffrey, I'm finally using a workaround based on the redirect after post pattern that consists of: 1) Always navigating using redirects in my navigation rules -- This solves the problem with refreshing and shows the correct URL on the browser (if not used, you always get the previous URL) 2) The problem with using redirect is that information is lost within the redirect process, like Faces messages (amongst maybe others). I posted a listener to avoid this problem. 3) In order to solve the problem with the back button, and always in combination with the redirect navigation, you can always include an script in the very first beginning of your page that does this simple function: script history.forward(); /script Hope it helps ;-) 2005/11/22, Jeffrey Porter [EMAIL PROTECTED]: Anyone? -Original Message- From: Jeffrey Porter [mailto:[EMAIL PROTECTED]] Sent: 21 November 2005 12:06 To: MyFaces Discussion Subject: HTTP re-post - another question.

BUT When I press F5 at this point, my page is re-submitted I get a Bean with the original values in, not an empty bean. I've seen people talk about the "redirect after post" pattern. Is this the correct path to follow? Or can I just make a call to removed the data when I redirect back to my original page? Jeff.
HtmlPanelTabbedPane Update Model
Hi, Is there a justification why the broadcast method of the HtmlPanelTabbedPane calls getFacesContext().renderResponse(), so the model doesn't get updated?

Why can't the change of a tab update the model? Is it something that I'm misunderstanding? Thanks for your support ;-)

The t:columns component, like dataTable is a subclass of UIData. The trick is that when t:columns renders a row it uses td instead

I mean, I only have one data model to populate the t:columns,

identifiers...2005/11/8, Mike Kienenberger
[EMAIL PROTECTED]:
There's no right answer; there are many solutions.It just has to besomething that you can use to look up the column value for the rowobject.From what you've said before, one possibility is to use a column data
model that contains the Integers 0 to 7 (or MaxPrivs-1).Then you can useObject row = rowDataModel.getRowData()Number indexNumber = (Number)columnDataModel.getRowData()Object row.columnValueAtIndex

You use a data model as value to the t:columns tag, and then that data
model is used to identify the column selected. So my question is: what kind of data model should I use so later any of my child objects can be identified? 2005/11/8, Mike Kienenberger
[EMAIL PROTECTED]: In my example, the columns were independent of the rows.
In your case, you'll have to first compute the maximum size.
Using my code, I'd do it something like this: == private columnList = null; public List getColumnList(){ if (null == columnList) {
List rowList = getRowList(); // iterate over the row list and determine the value for maxColumnCount columnList = createColumnListOfSize(maxColumnCount);
} return columnList; } public boolean getValueFor(Object rowObject, Object columnObject) { int columnIndex = columnObject.findIndex
(); if (columnIndex = rowObject.getColumnList.size ())return emptyObject; else return rowObject.getColumnList(columnIndex); } ==
Obviously, my model isn't a direct fit to what you're doing, but the basic logic is still the same. The first time you need it, compute the max-size column list. Then each time a row/column item is
accessed, return the column in the row if the row has that many elements, or return an empty object if it doesn't. -Mike On 11/7/05, Enrique Medina

[EMAIL PROTECTED]:My suggestion would be to adjust your column model so it always has 8
(or MAX) values for each row, and simply return empty (whatever thatmeans in your component) data for the remaining values. Alternatively, you could try:

I understand Mike :-) So if I have a collection of parent objects, which in turn each parent object has a collection of other child objects, then I can show a table where the first column is fixed and contains vertically the list of the parent objects, but for each row, the columns are dynamic and can show the collection of child objects for each parent.

Re: How to create component without binding?
The debug shows that:
1) The getter is only called every time the page is rendered coming
from another different page. If it is re-rendered (for example, because
you click on the tab), the getter is not called
2) The setter is called:
2.1) Just after the only time the getter is invoked
(I think this is the perfect point to create all the components)
2.2) Every time I click on the tab (simply return the parameter passed by JSF)
2.3) Sometimes when I navigate to another page (simply return the parameter passed by JSF - ignore it)
I also noticed then that I should always return null from the getter,
so every time this page is called, the components must be recreated, as
it is probably that the data has changed2005/11/4, Martin Marinschek [EMAIL PROTECTED]:
This won't work - on every request, your setter will be called by theJSF implementation. And on every request, you will get passed a newcomponent reference (except you do server side state saving, then thismight actually be the same) as it is serialized/deserialized from the
saved state.Can you debug in what happens with your get/set pair? You shouldeasily find out what is going out then...regards,MartinOn 11/4/05, Enrique Medina

2005/11/4, Martin Marinschek [EMAIL PROTECTED]: Well, for very easy situations, it is ok to create it in the getter, when it
is sure that your component will not change during the life-time of a view. For all other things, it is much better to provide a setter and initialize the component somewhere else so that you can dynamically
change the component and what it binds to. regards, MartinOn 11/4/05, Enrique Medina

But should be the best approach then? 2005/11/4, Martin Marinschek [EMAIL PROTECTED]
:What you want to do is do a binding for panelGroup and then add children to this panelGroup - with this you can createextra components.
code snippet (not compiled except in my head ;): public UIComponent getPanelGroup(){HtmlPanelGroup panelGroup = new HtmlPanelGroup();

Dynamic component creation
Hi,
I am trying to dynamically create some components inside my backing bean, but I can't get it to work right now...
Imagine I have to dynamically generate some tabs inside a
PanelTabbedPane, and one data table inside each tab, so I'll explain
what I am doing:
1) In my JSP I define the HtmlPanelTabbedPaneTag:
t:panelTabbedPane bgcolor=#F8F8F8 align=center
binding=#{puntuacionesBean.panelTabuladores}
and as can be seen, I bind it to my component in my backing bean (puntuacionesBean).
2) Inside my backing bean (puntuacionesBean), I declare a variable
named panelTabuladores with type UIPanel. Then I also declare a
getter and a setter for it.
3) When the page is rendered, the HtmlPanelTabbedPaneTag invokes the
HtmlPanelTabbedPane component, so my getPanelTabuladores method is
called. So:
3.1) I check whether my panelTabuladores variable
is null or not. If it is null, the I create myself the component, and
then I create all the components that will be the children of the
HtmlPanelTabbedPane (simulating tags inside tags):
if (this.panelTabuladores == null)
{
this.panelTabuladores = (HtmlPanelTabbedPane) FacesUtils
.getApplication().createComponent(
HtmlPanelTabbedPane.COMPONENT_TYPE);
UIPanel tab0 = (HtmlPanelTab) FacesUtils.getApplication()
.createComponent(HtmlPanelTab.COMPONENT_TYPE);
;
tab0.setParent(this.panelTabuladores);
tab0.setId(panelTab0);
tab0.getAttributes().put(label, Variable0);
UIData tabla0 = (HtmlDataTable) FacesUtils.getApplication()
.createComponent(HtmlDataTable.COMPONENT_TYPE);
tabla0.setId(tablaEdicionPuntuaciones0);
tabla0.setVar(puntuacion0);
tabla0.getAttributes().put(width, 100%);
tabla0.getAttributes().put(cellspacing, 1);
tabla0.getAttributes().put(cellpadding, 2);
tabla0.getAttributes().put(renderedIfEmpty, Boolean.FALSE);
tabla0.getAttributes().put(preserveDataModel, Boolean.FALSE);
tabla0.setValueBinding(value, FacesUtils
.getValueBinding(#{puntuaciones.listasPuntuaciones[0]}));
tabla0.setRows(10);
tabla0.getAttributes().put(rowClasses, impar,par);
tabla0.getAttributes().put(headerClass, apptblhdr);
tabla0.getAttributes().put(rowIndexVar, numFila0);
tabla0.getAttributes().put(rowOnMouseOver, tblOver(this));
tabla0.getAttributes().put(rowOnMouseOut,
tblOut(this, #{numFila0%2}));
UIColumn col1 = (HtmlSimpleColumn) FacesUtils.getApplication()
.createComponent(HtmlSimpleColumn.COMPONENT_TYPE);
col1.getAttributes().put(style, text-align: center;);
UIOutput texto1 = (HtmlOutputText) FacesUtils.getApplication()
.createComponent(HtmlOutputText.COMPONENT_TYPE);
texto1.setValueBinding(value, FacesUtils
.getValueBinding(#{mensajes.puntuaciones_Tramos}));
col1.setHeader(texto1);
UIOutput texto2 = (HtmlOutputText) FacesUtils.getApplication()
.createComponent(HtmlOutputText.COMPONENT_TYPE);
texto2
.setValueBinding(
value,
FacesUtils
.getValueBinding(#{puntuacion0.valor.minimo} -
#{puntuacion0.valor.maximo}));
col1.getChildren().add(texto2);
UIColumn col2 = (HtmlSimpleColumn) FacesUtils.getApplication()
.createComponent(HtmlSimpleColumn.COMPONENT_TYPE);
col2.getAttributes().put(style, text-align: center;);
UIInput texto3 = (HtmlInputText) FacesUtils.getApplication()
.createComponent(HtmlInputText.COMPONENT_TYPE);
texto3.setValueBinding(value, FacesUtils
.getValueBinding(#{puntuacion0.puntuacion}));
col2.getChildren().add(texto3);
tabla0.getChildren().add(col1);
tabla0.getChildren().add(col2);
tab0.getChildren().add(tabla0);
this.panelTabuladores.getChildren().add(tab0);
As can be
seen, I create every subcomponent and add it to the getChildren list of
the parent component.
3.2) I return the just initialized panelTabuladores variables as a HtmlPanelTabbedPane component
The problem is that the tabs are visible, but the data table seems to be absolutely ignored, as it doesn't appear in the page.
However if, instead of the data table, I simply create tab with a text
component inside it, then it is correctly displayed, so there must be a
problem I cannot see with my data table.
Any help would be really appreciated.
Re: Dynamic component creation
Hi Mike,
I've been taking a look to your code, and if I understand well, you
mean to do what you implement in the
RowAndColumnRelationshipsHtmlDataTable constructor, but within my
setter method inside my backing bean, don't you?2005/11/3, Mike Kienenberger [EMAIL PROTECTED]:
Enrique,Try a different approach.Put this code in your setPanelTabuladores() method. You don't needto create a HtmlPanelTabbedPane because this component is alreadycreated for you. All you need to do is create tabs and add them to
the table passed into the method. I think you should do this usingparent.getChildren().add(child) instead of child.setParent() as that'show I've always seen it done in the past.You can find a very old example I wrote of dynamically creating
components in a dataTable subclass as an attachment here. It mightbe of help.If so, the most interesting class isRowAndColumnRelationshipsHtmlDataTable as it does all of the creationwork.

EL Maps
Hi, I was trying to use an EL reference to a Map defined in my backing bean, but I always get null as a result. Doing some code reviewing I have seen that MyFaces uses the ELParserHelper class to invoke the Apache Commons library, but only gives support to arrays through its MyArraySuffix static inner class. Does this mean that no support for working with EL and maps in MyFaces is given? Am I missing something?
Re: EL Maps
Hi,
Yes I have both a getter for the map and a setter, which returns the whole map.
Let's put my example:
JSP EL _expression_ -- t:dataTable value=#{puntuacionesBean.listasPuntuaciones['2'].value}/
Bean PuntuacionesBean --
public Map getListasPuntuaciones()
{
// Imagin something like...
this.puntuacionesMap = new HashMap();
this.puntuacionesMap.put(new Integer(2), //someValue);
return puntuacionesMap;
}
public void setListasPuntuaciones(Map listasPuntuaciones)
{
this.listasPuntuaciones = listasPuntuaciones;
}
If I debug the code, the value binding returns null when getting the value for the data table...
2005/11/2, Stefan Gesigora [EMAIL PROTECTED]:
Hi Enrique,you always need a getter and a setter method for the map.Then you can use it with the EL in this way:h:inputText binding=#{test1Bean.map['t3']}/If you use a list:
h:inputText binding=#{test1Bean.list[1]}/regards,Stefan-Ursprüngliche Nachricht-Von: Rick Gruber-Riemer [mailto:[EMAIL PROTECTED]
