AW: Problem with PanelTabbedpane
I think an
instance of your TabSupport class is created every time you change the tab
(that's what I remember, I had a similiar implementation at the beginning). That
would explain why your selectedTabIndex property value does not reflect your
current index, but always the default value.
You may try to
create a separate Backing-Bean class to store the selectedTabIndex. And you can
update this property from theprocessTabChange method in another class (no
Backing-Bean) by looking up a reference to the Backing-Bean every time your
processTabChange methodis called.

PanelTabbedpane
Hi
I m trying to use the panel tabbed pane with the serversidetabswitch =
true. Therefore I have declared a tab change listener with the following
source code
public class TabSupport implements Serializable, TabChangeListener
{private static final long serialVersionUID = 1L;int
selectedTabIndex;public
TabSupport(){}public int getSelectedTabIndex() {
//System.out.println(" Property getSelectedTabIndex() accessed
" + selectedTabIndex);return
selectedTabIndex;}public void setSelectedTabIndex(int
selectedTabIndex) {//System.out.println(" Property
setSelectedTabIndex() accessed"); this.selectedTabIndex =
selectedTabIndex;}
public void processTabChange(TabChangeEvent
event){System.out.println("TabSupport:processTabChange()
called " + event.getNewTabIndex() + " " +
event.getPhaseId());this.selectedTabIndex =
event.getNewTabIndex();}}
When I change the tabthe listener is invoked which sets
selectedTabIndex value accordingly and I can see this through the system
message. But in the generated html the selectedtab content doesnt show
meaning selectedTabIndex is still 0. It hasnt been assigned to the new
valueor has been overwritten.TabSupport is in the session scope.

Betreff: Re: Re: problem with panelTabbedPane on winXP and IE6
Hi,
would be better if we fix that issue in the component directly. I will
have a look on that.
The server side switch does a round trip to server in every case when
you are switching to the next tab, this requires a post and so there
is the need of a button. Client side does the switch only via js, thus
no model update will take place.
If you have a look at the myfaces simple examples, there are two
tabbed panes on the page. The first comes with the setting
serverSideTabSwitch=false. Second is set to true, there you get the
problems with the button.
I am just wondering, if you don`t specify this attribute - default
should be client side - the button should not be displayed.

Hi,
Yes, you are right. This is only a missinterpreting issue with IE, and
only if you you set the panel to serverSide tab switch. Because you
have to do a post, the button is rendered.
You can easily access it with:
.activeTabClass input { ... }
This will also only affect the tab, and not the whole tab-page!

This applies the css to all inputs on the page and I only want the

I created a stylesheet class using the same properties as before.

}
and assigned it to all the different style class attributes
(activeTabStyleClass...) for the panelTabbedPane and panelTab tags.
I'm a newbie at css but I thought this should have worked but
it didn't.
Any one have any idea how I can assign this style sheet just the the
tab's input button and not the ones on the rest of the page?

AW: How does JSF associate a session?
To make sense of this behaviour, try to disable cookies first and see what happens. you'll see the jsessionid always, and you'll have your desired behaviour (if you open a new window, you'll get another jsessionid as well) Thanks. The problem was my approach of initializing Backing-Beans in an access controller Servlet and providing them to JSF by using the ServletContext. Bosch described this approach in his JSF book, but didn't mention that the Backing-Beans will then be shared by different sessions... No I changed this and use the standard constructors of the Backing-Beans, which will be called by JSF. Does someone of you know another approach for providing Backing-Beans to JSF from outside of a JSF request (non-faces request generates faces response)? -Matthias As soon as you enable cookies, the session will be round - it will stick, until the cookie is cleared again. regards, Martin On 3/23/06, Matthias Kahlau [EMAIL PROTECTED] wrote: How did you open a new browser?

I believe this is the dreaded converter timezone problem which can be

set stuff which is repeatable across the whole app (like a
converter=#{converterBean.converter}) and styles.

RE: multi-selection in selectOneListBox
Thanks for the
answer. I was trying to use this selectManyListBox but I got into troubles to
get the selected items.
Please would you mind
telling me what I am doing wrong:
-
I
initialized my list of trades:
protected
ListSelectItem allTrades = null;
allTrades
= xmlParse.getAllActiveDimensions("Trade"); //all
trades are correctly displayed in my jsp page
-
I
initialized my list of selected trades:
protected
ListString selectedTrades = null;
this.selectedTrades
= new ArrayListString();
-
I
have getters setters on them
public
ListSelectItem getAllTrades(){
return this.allTrades;
}
public
void setAllTrades(ListSelectItem
allTrades){
this.allTrades = allTrades;
}public
ListString getSelectedTrades(){
return this.selectedTrades;
}
public
void setSelectedTrades(ListString selectedTrades)
{
this.selectedTrades = selectedTrades;
}
-
I
add the code to display the trades in my jsp page:
td
style="width:150px"
h:outputText value="#{Fmsg.authorizedTrades}"
/:BR
h:selectManyListbox
id="trades1" value="#{MyClass.selectedTrades}" style="width:150px"
f:selectItems
value="#{MyClass.allTrades}" /
/h:selectManyListbox
/td
-
I write all the
selected trades in a file but none are written:
try
{
BufferedWriter out = new BufferedWriter(new
FileWriter("selectedTrades.txt"));
for (
String sel : this.selectedTrades)
out.write( sel );
out.close();
} catch (IOException ioe) {
System.out.println(ioe.toString());
}
But here the file is
created but nothing is written inside! What do I do
wrong?

Hi,
you may use the
selectManyListboxof the Standard HTML RenderKit Taglib. It displays all
options at the same time and allows the user to mouse select many
optionswhile holding the CTRL-Key.

safely
I know I am doing hacks because MyFaces does not display beautiful
messages in my case.
In a phase listener (after Model Update), I tried to remove
FacesMessage(s) with generated ID like "_idJsp123"
FacesContext context =
event.getFacesContext(); IteratorFacesMessage
itr = context.getMessages(); while (itr.hasNext())
{ FacesMessage message =
itr.next(); if
(message.getDetail().indexOf("_id") =0
)
itr.remove(); }
Removing was successful without error. But during Render Phase, an error
showed up. It seems that thereferenced FacesMessage isnot
found. I do not understand how it happens. If a FacesMessage is deleted from a
collection, and it is still ref erenced by others, it will not be gabage
collected.
Is there a way to remove FacesMessages safely? Thanks!

AW: JSF value Change Listener Problem
Hi again! Hi! Does that mean all listener happens BEFORE the update model phase? Include action listener No, the action listener fires after the invoke-application phase, which is after the update model. All this after and before ;-) In fact the action listener fires during the invoke-application phase. If the UICommand component is configured with immediate=true, the ActionEvent will be processed at the end of the Apply Request Values Phase. -Matthias Havent had some tee today thanks Dennis for keeping an eye on me :-) ! Ciao, Mario
AW: selectOneMenu and valueChangeListeners
Hi! Do you change the model properties of the other two selectOneMenus when you processtheValueChangeEvent of one selectOneMenu? This may cause firing new ValueChangeEvents, I can remember such a problem.You may try to comment out these changes and see, if the other methods are still called. An alternative might be the valueChangeNotifier component, which processes ValueChangeEvents after the Update Model Values Phase.

Problem with dataScroller images
Hi! I have a problem with the dataScroller contained in a tab of a tabbed pane. The images are shown correctly when the page is initially loaded, when I navigate between the tabs and when I perform an action the causes to display the same tab again. But when I leave the tab to a form not contained in the tabbed pane, and then return to it, only placeholders, and not the images are rendered, until I force the page to redisplay. Can you image what might cause this, and how to solve it? (I use the filter mapping described on the MyFaces Web page.) Matthias

AW: stateful/stateless JSF components
The classical example is a tabbed pane. With a server side rendered, you
trigger a request at every tab change going through all the hoops, with
a client side one, you have to do more loading upfront because you load
all the components and values, but in the best case that is it, even if
you switch the tabs 100 times you wont trigger any other request onto
the server until save is hit.
I think there's no difference between client-side and server-side
tab-switching of the MyFaces panelTabbedPane regarding the rendering
behaviour. I did expect that, when using server-side tab-switching, only the
active tab's content would be rendered, but looking at the HTML source
returned with the response showed me, that the content of all tabs is
contained. The contents of the inactive tabs are only made invisible by
using CSS.
I use MyFaces Nightly 20051130 - maybe it's a problem with this version
only.

Thomas DELHOMENIE schrieb:
Thank you Werner for your answer.
If I understand what you say, a stateless component doesn't
exist on the
server between 2 requests, that's right ?
And a component like h:outputText doesn't need to be stateful contrary
to a more complex component like a tree, am I right ?
well in certain situations it makes sense to have outputtext being state
aware but in many not, and that is the real problem.
In a classical rich client ui every component you use is state aware per
default without any costs, but adding that layer to a server side
rendered ui on top of a stateless protocol is a huge burden.
The main problem is where do you draw the boundaries of having to have a
stateful component and a non stateful.
h:outputText value=show this text/ for sure can be non stateful
with
h:outputText value=#{something dynamic}/ you already might have a
problem on your hands in some conditions.
(output text probably is a bad example nevertheless lets leave it)
So where do you draw the line and where can you draw it automatically.
I am not sure if it is a good idea to go entirely stateless, you would
lose the biggest advantage of jsf the programming model of a rich client
ui that way, you would end up with a simplified Struts.
I only see two solutions, give the users the opportunity to turn off the
stateful behavior on component level, and the one Adam Winer was
showing, improve the state saving on algorithmic level. (After reading
Adams blog, I see a huge potential here)
But at one point there always will be a tradeoff, but that tradeoff has
to be done manually on non stateful frameworks as well, with myriads of
hidden fields or session states kept around programmatically to keep the
ui states.
Becoming more dynamic on the client side also might be a reduction on
the burden, not because you reduce states that way (after all the ajaxed
and javascripted ui states have to survive a request cycle) but because
you can reduce server side load tremendously that way.
The classical example is a tabbed pane. With a server side rendered, you
trigger a request at every tab change going through all the hoops, with
a client side one, you have to do more loading upfront because you load
all the components and values, but in the best case that is it, even if
you switch the tabs 100 times you wont trigger any other request onto
the server until save is hit.
AW: AW: stateful/stateless JSF components
And if it is true what you say then the load savings due to the client side tab switching on the myfaces tabbed pane is even more, because you stream the entire data only once instead of at hitting the tab every time. You're right, but I think developers should make design decisions in favor of the user, if that's possible. And users with a slow network connection won't be happy if they have bad response times because of streaming the entire data of all tabs at once. Maybe users do not need the data of inactive tabs at all. Regards, Matthias -Ursprüngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Auftrag von Werner Punz Gesendet: Freitag, 3.

Do you have no idea? What can be wrong that a property value accessed by a
reference of a Backing-Bean after a lookup is not the same value than it is
in the accessor method of the Backing-Bean itself?
Please have a look at the example below. I can't find a coding error, so
your general ideas of what might be wrong could really help me...
(The lookup is normally not performed in the accessor method, it's only an
example that shows the value discrepancy. The property value retrieved by a
lookup of the Backing-Bean is 'null' in any case.)
Regards,
Matthias

I did some further investigations and could limit the possible
causes. The
Backing-Bean's selectedIndex property is 'null' only when a Backing-Bean
lookup is performed to read the property value (the Backing-Bean is in
session-scope!).
Example with logging output in the property's setter method
(please note the

Betreff: Re: Rendered markup of HtmlSelectManyCheckbox /
HtmlSelectOneRadio incomplete?
Hi Matthias,
Matthias Kahlau wrote:
Hi!
My HtmlSelectManyCheckbox with spread layout and a styleClass set is
rendered as follows:
table border=0
tbody
trtdinput type=checkbox name=Form:Frage_4 id=Form:Frage_4
value=1 class=surveyInput /#160;die zweite (Text)nbsp;/td/tr
trtdinput type=checkbox name=Form:Frage_4 id=Form:Frage_4
value=2 class=surveyInput /#160;die dritte (datum)nbsp;/td/tr
/tbody
/table
This does not comply to the Standard Html RenderKit
specification of JSF
1.1 for the HtmlSelectManyCheckbox renderer:
You're right, layout=spread is out of spec ;-).
Render a table element. If the styleClass is specified, render the
value of the styleClass attribute as the value of the class
attribute on
the table element. If the style, border attributes are
specified, pass
them thru. If the layout attribute is specified, and its value is
pageDirection, render the children elements vertically, otherwise
horizontally, in the table. If any of the children are an instance of
SelectItemGroup, render them as a nested table. Each of the children are
ultimately rendererd as follows. Render a label element. Inside of the
label, render an input element of type checkbox for each child
component. ...
The class surveyInput (set to the HtmlSelectManyCheckbox component) is
rendered only as attribute in the input elements themselves,
but not for
the table. Furthermore, the Tomahawk HtmlSelectManyCheckbox
renderer doesn't
render a label element around each input element. Why did
you choose a
different markup?
In contrast, the Tomahawk HtmlSelectOneRadio component's markup
(spread
layout) does contain label elements as required, but shows the same
behaviour regarding the styleClass attribute of the component:
table border=0tbody
trtdlabelinput type=radio name=Form:Frage_2 checked=checked
value=1 class=surveyInput /#160;die zweite
(Texteingabe)/labelnbsp;/td/tr
trtdlabelinput type=radio name=Form:Frage_2 value=2
class=surveyInput /#160;die dritte (nur
Ganzzahlen)/labelnbsp;/td/tr
/tbody/table
As Hans Bergsten describes in his JSF book, the label
elements should also
specify their for attributes, which isn't the case for the code snippets
shown (using MyFaces Nightly 20051130).
The label element is my lifesaver in changing the format of the radio
button labels, and I really need them for the checkboxes, too.
I don't know
how to change the format of the checkbox labels, because I
can't change the
table, tbody, tr or td elements per CSS globally, and applying a
style to the HtmlPanelGrid containing the checkbox controls is not
sufficient in my case because there's a global definition for the td
element which a must not change ...!
Do you have an idea of how I could change the checkbox label format?
not sure, but maybe you can use the descendant modifier of css:
http://www.w3.org/TR/REC-CSS2/selector.html#descendant-selectors
try:
--- [css] -
#panelGridId td {
// css for label tds here
}
--- [/css] -
Or even better:
Create a patch for this to accept a 'labelClass' attribute and rendering
the label tag for checkboxes also.

Volker

AW: Setting CSS Programatically
To get this to work for the entire row you will need to add the :

Yes, I already thought that way, but I think setting the column styles might
expose a different behaviour than setting the row style. Anyway, your

There's a use case where I encounter a problem with my solution.

outputLink modifies the specified value
Hi!
I use the following outputLink:
h:outputLink
value=#{UmfrManUmfrTabBacking.accessControllerNonPortalURL}#{row.id}
title=Kopieren und weitergeben fuer die Teilnahme
h:outputText value=Teilnahme styleClass=standardLink /
/h:outputLink
The JSF EL expressions in the value attribute of the outputLink evaluate to
the following URL parts:
#{UmfrManUmfrTabBacking.accessControllerNonPortalURL} =
http://localhost:/login_nonPortal?surveyId=
#{row.id} = 38
login_nonPortal is a URL pattern used for a Servlet.
servlet-mapping
servlet-nameAccessControllerNonPortal/servlet-name
url-pattern/login_nonPortal/url-pattern
/servlet-mapping
When the URL is displayed, the following URL is generated by JSF for the
outputLink:
http://localhost:/Umfragesystem/faces/Management/38
/Umfragesystem is the context path of the web application, /Management
is the path to the current JSF page.
Do you know why JSF modifies my outputLink value and how this can be
prevented?

Hi Volker! Thanks for your support. I'm not sure, but maybe you should try throwing a javax.faces.validator.ValidatorException in your validation method when your validation fails. I don't use a validation method. I use required=true, and when nothing is entered, a standard validation error occurs displaying the same view again. My tree structure depends on the survey that is shown to the user. In my example where the error occurred, there have been two data tables with some rows of radio buttons and other components for other question types, e. g. 2 HtmlSelectOneMenu, 4 HtmlSelectManyCheckbox, some HtmlInputText and HtmlInputTextarea. The components are all children of the one form used in the view. All works fine, except when a validation error had occured, so please try with a standard validation error.

The German language Locale format looks correct. f:convertDateTime dateStyle=short type=date / - German Locale: 25.01.2006 - English Locale: Jan 25, 2006 (- looks like medium format) Do you have an idea how to solve this?

AW: AW: Problem with evaluation of Tomahawk HtmlSelectOneRadio components inside UIData (programmatically created UI)
Hi Volker, many thanks, it works now. I already tested it with the HtmlSelectOneRadio components outside of UIData, but I got runtime errors because they hadn't been found for the related HtmlRadio components. That's why I added them as children to UIData, what solved the error, but the evaluation didn't work. Using the HtmlSelectOneRadio components outside of UIData and specifying absolute IDs in the for attribute did the trick... Now I can use a table with table headers for each column, what hadn't been possible with HtmlPanelGrid.

Tomahawk TLD - Why always rtexprvaluefalse/rtexprvalue?
Hi! I've a question related to the TLD of Tomahawk. Why are all attributes declared with rtexprvaluefalse/rtexprvalue, although some can be dynamically calculated at runtime by an EL expression? Sometimes I need to know if a specific attribute accepts a JSF EL expression, but how can I know that? Is there another information source available? Regards, Matthias
Problem with evaluation of Tomahawk HtmlSelectOneRadio components inside UIData (programmatically created UI)
Hi! I tried to use a Tomahawk HtmlDataTable to programmatically display a matrix containing questions in the left column and some radiobuttons in the other columns. I added a HtmlRadio component to each HtmlSimpleColumn instance. For each row, I added a HtmlSelectOneRadio component to the table. The HtmlRadio components for attribute uses a value-binding to the current row object of the data set, to get the ID of the related HtmlSelectOneRadio component. I don't know if I've followed the right approach. The table is displayed correctly, but the evaluation of the selected radiobuttons doesn't work. It doesn't matter was has been selected, I always get value=1 for each HtmlSelectOneRadio component. Maybe this is the wrong approach. Do I have to use only one HtmlSelectOneRadio component with a component binding, and process the selections by iterating over the UIData's data set, like it is done when using JSP?

AW: Tomahawk TLD - Why always rtexprvaluefalse/rtexprvalue?
rtexprvalue is meant for JSP-expressions, and not JSF expressions - and you cannot use JSP-expressions in tag-attributes. You can use JSF-EL in all attributes except ids, I believe. Correct me if I'm wrong. Thanks. That sounds good... If you're wrong, it would really be of help if there would be a way to recognize the rules...

When processing the user input, the HtmlSelectOneRadio components are
located by using the findComponent() method of the UIComponent class.
This works well. Then the submitted or local value is evaluated (taking the
one which is not null), and it's always the initially selected value, no

Applying style to radio button / checkbox labels
Hi! I have to add some style to the text shown with a radio button or checkbox (using HtmlRadio or HtmlCheckbox), not to the controls themselves. A HtmlSelectOneRadio or HtmlSelectManyCheckbox has a styleClass attribute, but the settings do only apply to the controls themselves, not to the labels. My radio buttons are rendered as follows: tdlabelinput type=radio name=Form:Frage_7_2 value=4 class=surveyInputRadioCheck /#160;d/label/td - There is a label element around each radio button, which is rendered implicitely. Is it possible to set a style to that label elements? My checkboxes are rendered as follows: tdinput type=checkbox name=Form:Frage_7_4 id=Form:Frage_7_4 value=2 class=surveyInputRadioCheck /#160;zweite/td - Unfortunately, there's no label element around the checkbox elements (Why not?). The class surveyInputRadioCheck doesn't affect the text of the control... So how can I apply some style to the control's labels? I can't define a global style for td or label elements - that could inadvertently destroy other layouts... The most important style I have to apply is a margin or padding to add space between multiple columns of radiobuttons or checkboxes. That would improve the usability of the UI... Regards, Matthias

With JSP, I only had a selectBooleanCheckbox in a column of the dataTable.
It had a component binding and I could access it after setting the rowIndex

In my current case, I need multiple radiobuttons (HtmlRadio components) in

what should I set the HtmlRadio components for attribute to? I have only

I wonder about that, because processing the user input after locating the

use (without UIData), e. g. by using
- only one HtmlSelectOneRadio component and some HtmlRadio components,

Has this sth. to do with UIData?

AW: Problem with evaluation of Tomahawk HtmlSelectOneRadio components inside UIData (programmatically created UI)
For UIData, not a thousand components represent thousand rows,
but only one.
But I didn't use only one HtmlSelectOneRadio component for all rows.
Instead, I use many HtmlSelectOneRadio components, one component for one
row.
Using one HtmlSelectOneRadio component for all rows had only been a
potential solution. Your explanation kills this idea for the moment, but I
think it doesn't explain why my current solution doesn't work...

Yes, it has somehting to do with UIData.

I wonder about that, because processing the user input after
locating the
components by using findComponent works for all the other
question types I
use (without UIData), e. g. by using
- only one HtmlSelectOneRadio component and some HtmlRadio components,
- only one HtmlSelectManyCheckbox component and some HtmlCheckbox

- only one HtmlInputText or HtmlInputTextarea
Has this sth. to do with UIData?

Ok,
I do think I know now what your problem is:
the findComponent will deliver a component which is not properly
initialized (it will return the stamp, but not the actual initialized
component for this row...)
So what you're really looking for is the functionality I implemented a
few weeks ago for findComponent, to return a properly initialized
component for this row.
But: I can't help you out with fixing this in the radio-renderer right
now, sorry. And you're in stress, too, to get your thesis finished,
right? So I really don't know how to fix this. no clue.
Anyone else able to help?

Hi Ali,
there are some things you made wrong:
First, and this seems to be a popular error: you can't add a component
to another by setting the parent of the child! use
parent.getChildren().add(child) instead.
Than: You dont neet to invoke encoding on every component, just create
then component tree and let jsf do the rest.
Try this :
public void encodeBegin( FacesContext context )
{
HtmlPanelGrid panelGrid = new HtmlPanelGrid();
panelGrid.setColumns(2);
List children = panelGrid.getChildren();
UIOutput labelName = new UIOutput();
labelName.setValue(Enter name: );
labelName.setId(nameId);
children.add(labelName);
UIInput inputName = new UIInput();
inputName.setId(inputNameId);
// UIInput needs a valueBinding
children.add(inputName);
UIOutput labelAge = new UIOutput();
labelAge.setValue(Enter age: );
labelName.setId(ageId);
children.add(labelAge);
UIInput inputAge = new UIInput();
inputAge.setId(inputAgeId);
// UIInput needs a valueBinding
children.add(inputAge);
this.getChildren.add(panelGrid);

How to set the width of columns in a panelGrid?
Hi! Is there a way to define the width of columns when using a panelGrid element? Regards, Matthias
AW: AW: AW: AW: Panel Grid custom component
Hi! So you are right, in this point UIData and panelGrid are similar, but i think this are not the headers you want. No, I see. I don't explicitely use columns in a panelGrid, so I can't add facets as children of column components, neither in JSP nor programmatically. It seems like I have to use HtmlDataTable, but this will be more complex than using a simple HtmlPanelGrid...

How to programmatically add a table header to a HtmlPanelGrid?
Hi! When using JSP and dataTable, I can add f:facet name=header.../f:facet within more than one column. But now I want to add a table header to a HtmlPanelGrid when programmatically creating the UI components. It seems there's no facet component to use, and I have to use panelGrid.getFacets().put(header, header); This looks like only one header facet can be added. But I need to add more facets. And I think I can't use a container component for the header component (e.g. another HtmlPanelGrid), because the cell borders of table header and body have to be aligned. Do you know a solution?

Essentially the navigation handler does the following things. Is is a redirect? If yes do a redirect via the external context. If no, call viewhandler create view, set the view id, call faces context set view root, and then render response. Long text, short message: try doing your own navigation handler.

The stables are not to bug ridden anymore like they used to be 1-2 years ago, huge improvements happened in this area.

Even if not for other reasons than that you have a clear reproducable tagged library version.
Problem with UIData access in session scope when UIData is transient because of serialization
Hi! I have the following problem: - Backing-Bean property of type UIData (component-binding) - Backing-Bean is in session-scope - Backing-Bean implements Serializable - Backing-Bean has deleteSelected() method to delete selected rows in the UIData - Backing-Bean has scroll() method to scroll the UIData after deletion - deletion is not performed immediately when processing the postback, but a confirmation dialogue is shown first - so deletion is performed after confirming the dialogue There are two scenarios: 1) Backing-Bean property of type UIData (component-binding) is transient - That's necessary to make the Backing-Bean serializable - Marked as transient, the UIData can only be accessed in the postback - later, it is null! - That's a problem when the UIData selection evaluation or the scrolling is performed after showing the confirmation dialogue... (I can temporarily store the selected objects by accessing UIData before the confirmation dialogue, but it's bad to scroll before showing the confirmation dialogue, because the user may decide ro not delete, and the I cannot scroll back because UIData is null (or is this possible in any way?)) 2) Backing-Bean property of type UIData (component-binding) is NOT transient - My Backing-Bean is not serializable anymore - JBoss throws NotSerializable Exceptions - But I can access the UIData after showing the confirmation dialogue, too (not only when processing the postback) My Backing-Beans should all be serializable, so do you have an idea of how to access UIData in requests after the postback, when UIData is marked transient? (By the way: Can you explain why UIData not marked transient is accessible in requests after the postback and not accessible when it's marked transient?) Any help would highly be appreciated... Regards, Matthias
javax.faces.application.StateManager.SerializedView cannot be found
Hi! I use the myFaces-all.jar nightly from 20051130. When I try to use the SerializedView class, it cannot be found (that's what JDeveloper says to me...). import javax.faces.application.StateManager; works! import javax.faces.application.StateManager.SerializedView; fails! Do you know the reasons? Many thanks. Regards, Matthias
