Re: Converter error during Model update

The tags are processed in order of appearance, so if the listbox is first, it'll be processed (at each phase) first. So the problem is located in step 3, validating the inputText component. Step 1 is ok, I checked what happens in the userConverter and that looks good. There is also no problem during the validation of the selectOneListbox. But now during the validation of the inputText component in steo 3 selectedUserBean.selectedUser is still null. I think because the model wasn't updated yet, the method processUpdates was not called so far. Yes, that was what I was thinking at first, too, but since you're still in processValidations, the inputText isn't referencing selectedUserBean.selectedUser yet. It's still working with the component value directly. So if I'm right, that tells me that I can't select an edit a user on the same page. I need to separate the selection of an user in a first page and the modification of the user fields in a second page. But I don't like this idea. The only reason I could see this happening is if the inputText appears before the selectOneListbox on the page.
Re: Is ther a way? Life cycle for commandButton
What about callling this.setFlag(true) as the first line of code in
#{bean.check}? If it's a matter of having both true and false,
create checkTrue() and checkFalse() -- you can even have them both
call check() after setting the flag value.

h:form
h:commandButton value=Check
action=#{bean.check} immediate=true
t:updateActionListener property=#{bean.flag}

/h:commandButton
/h:form
What I need is:
set a flag(boolean) before Model update phase, then
go to Model update phase, then
go to Invoke Applicate phase, call the action method.
However, set immediate=true, both Action listener and action method are
executed in ApplyRequestValue phase, and Model update is skipped.
If immediate= false, normal life cycle. Action listener and action method
are executed in InvokeApplication phase.
Both ways are not what I need.
Using param under commandButton will solve the problem.
Model update setter methods can check the param value.
But this can be a security issue because client can pass a parameter in URL
to collapse the server side.
Any other solutions?
Thanks for ideas.

Re: No variables in t:column header facets! Bug?
UIColumns is basically a UIData turned sideways
So you have a data model for your rows, and then you have a second
data model for each of your columns.

Re: Do I need to set up .jspx extentions in my web.xml?
You are only allowed to have one suffix with the default JSF implementation. context-param param-namejavax.faces.DEFAULT_SUFFIX/param-name param-value.jsp/param-value /context-param or context-param param-namejavax.faces.DEFAULT_SUFFIX/param-name param-value.jspx/param-value /context-param You could create your own view handler that does this. Facelets delegates non-facelets file extensions back to the default viewhandler so that it can support both .xhtml and .jspx (for example). It'd seem like it'd be fairly simple to extend the default viewhandler functionality to try two suffixes instead of one. There's been interest (for this very reason) expressed by others in the last week for the same functionality. Search through the past week's myafces-users list for DEFAULT_SUFFIX to find the threads.

I'd recommend instead that you provide Jenai4Faces with a patch so that their components can be configured to use tomahawk directly. Helping them support both a tomahawk-specific configuration in addition to a JSF-independent configuration for their components should be done in such a way as to make it work for all of their components, and will allow those who best understand the PopupBox component (the original authors) to continue maintaining it, while still allowing you to take advantage of Tomahawk resource management. If they are not interested in supporting a Tomahawk-specific configuration, then perhaps you could join the jsf-comp sourceforge project at http://sourceforge.net/projects/jsf-comp/ and provide your port of the component from there. Again, other MyFaces PMC members may feel differently about it. You might get more of a response for pure MyFaces Development issues by using the MyFaces dev list.
Re: actionListener not invoked
The confusion is probably caused by the fact that a UICommand
component needs to have a rendered attribute that is page-scoped
rather than request-scoped.
The rendered attribute value needs to remain constant from the first
request's RenderResponse phase until the next request's
InvokeApplication phase.
This is because each phase checks to insure that a component is
rendered=true before executing for a particular component.
If the rendered value is only true during the first request (for
generating html representation), then during the second request, the
component will not exist to generate action events.

Use a request-scoped bean and use t:saveState to recreate it each page.
Or use a session-scoped bean.

Re: Skip Validation Phase
My first attempt to solve such a problem was to create the OptionalValidationFramework discussed on the wiki, but I don't really like that approach. It worked for me because I had a lot of dropdowns on the page. You might take a look at using the Sandbox subform validation as an alternate way to do optional validation. If you have only a few components that need to work like this, you could manually perform the update model phase yourself.I haven't tried it, but you might be able to call component.processUpdates() in your handler. Otherwise, you can manually grab the submitted or validated local value from the component, and manually put it into the backing bean. On 3/23/06, Yura.Tkachenko [EMAIL PROTECTED] wrote: Ok, Thanks.

The patch I applied for serverSideTabSwitching is a trivial one. It
merely fixes a bug where you were required to use #{true} instead of
true
You can build the latest code snapshot (or use a nightly build if you
don't need the sandbox) to pick up the patch automatically.
Otherwise, I'd recommend just using the workaround -- #{true} for
true and #(false} for false until your next upgrade.

Or I'm doing any wrong in placing/adding PhaseListener ?

Do you mean using a managed property and a more complex setter as an alternative? Is this a better approach than the check in the getter? It's had to say without knowing specifically what you're doing. Personally, I haven't had the need to manually create a component in the getter. From what you've posted so far, it doesn't really sound like you need that functionality either. It sounds like all you need is a reference to your selectOneMenu component. It also sounds like you have a couple of different issues you're trying to deal with: Seralization as well as a selectOneMenu that immediately changes what's displayed on the page. I've got more experience with the second. There's no really good way to handle the second case yet. Some of the ways I've seen so far are - OptionalValidationFramework (doesn't work well if you're not using facelets so I'd only suggest it if you have either a lot of immediate controls and are using facelets) - the new sandbox subform stuff (or the ADFFaces equivalent if you're using ADF), - manually updating the backing bean from your immediate actionListener via a component reference - using the delayed valueChangeListener component (I think it's called ValueChangeNotifier or StateChangeNotifier?) Again, you might get better advice if you post a bigger picture of what you're trying to accomplish since some of your reported problems may be irrelevent with a different approach.

It's possible if you were using serverSideTabSwitching=true that this bug was fixed earlier this week. Try it with a nightly build. The serverSideTabSwitching state was not being saveState'd.

Do the columns displayed change? If not, then you only need a regular
h:dataTable and h:column. (Of course, you can also use the
t:dataTable/t:column for extra functionality, but you don't have to do
so).
ie,
h:dataTable value=#{yourBean.yourRowModel} var=rowObject
h:column id=column1 .../
h:column id=column2 .../
h:column id=column3 .../
/h:dataTable
If the columns are dynamic, then you'd need to use t:dataTable and
t:columns (with an s).
t:dataTable value=#{yourBean.yourRowModel} var=rowObject
t:columns value=#{yourBean.yourColumnModel} var=columnObject /
/h:dataTable
Re: n x n dataTable (myFaces)
You'd write a java class implementing DataModel, probably. You could
implement List instead if you liked. Make it into a managed bean,
and then assign your source list as a property to it.
For example
class ConsolidatedList implements List {
public ConsolidatedList()
public void setSourceList(List list) { ... }
public List getSourceList() { ... }
public int size() { return sourcelist.size() / 3 }
public get(int index) {

Re: Problems with tree2 and facelets
No, this is a good place to ask. The tree2 component doesn't work seemlessly with facelets. Fixing that is on the todo list. http://issues.apache.org/jira/browse/TOMAHAWK-47 A quick workaround is to use the following attribute names instead: // Tree2 attributes public static final String SHOW_NAV= org.apache.myfaces.tree2.SHOW_NAV; public static final String SHOW_LINES = org.apache.myfaces.tree2.SHOW_LINES; public static final String CLIENT_SIDE_TOGGLE = org.apache.myfaces.tree2.CLIENT_SIDE_TOGGLE; public static final String SHOW_ROOT_NODE = org.apache.myfaces.tree2.SHOW_ROOT_NODE; public static final String PRESERVE_TOGGLE = org.apache.myfaces.tree2.PRESERVE_TOGGLE; Ie, org.apache.myfaces.tree2.CLIENT_SIDE_TOGGLE=true However, this will break at some future point when we fix the issues with tree2. You can also quickly write a facelets component handler to alias each of these properities to the fully-qualified name. Just follow the simple example here. https://facelets.dev.java.net/nonav/docs/dev/docbook.html#dev-meta-component You can also go into the myfaces source code and change the definitions in JFSAttr to remove the fully-qualified names -- this has been a popular approach :) There's a similar issue with some of the t:dataTable attributes, also fixable in the same ways.

You can either create your own custom renderer for dataTable, or you can manually render everything by using a dataList on your page and adding all of the table-building tags explicitly -- you'll need to drop the column components from your page code if you go that route.

The most preferred documentation format would be an xdocs file (for a good example, see the validateCompareTo component in the sandbox). mvn site to build the xdocs into a static html target.

This is no more than a stopgap. We'll use it for now, but we're akin

encapsulated, parameterized entity?
On of the features of component oriented development, in my view, is
that it is easy to define new components as combinations of existing
components. Take for instance the combination label, input field, and
error message.
h:outputText id=myProperty_label
value=#{myHandler.myPropertyLabel} /
h:inputText id=myProperty value =#{ myHandler.myProperty} /
h:message id=myProperty_messages for=myProperty /
This occurs many times in any JSF application, and it is bad practice
to copy-paste this pattern all over your application. The pattern
should be encapsulated (I'm actually talking about more complex
combinations, but as an example, this will do). The encapsulation
mechanism should allow for variation, of course. The easiest way of
variation is parameterization. In the example, we want the handler and
the property name to be parameterized.
We have been this way with JSP, following the history of programming
languages. Static includes gives us the possibility to reuse code
(macro languages). Dynamic includes give more flexibility, but
parameterization is not supported. We can communicate from calling
code
to called code through request, session or application scope
variables,
the way original COBOL and FORTRAN allowed communication into
subroutines only via global variables (there was only 1 kind). With
ALGOL we finally got procedures that feature formal parameters. In JSP
2, wefinally thanked the gods for .tagx files: an easy way to
combine
existing tags, that can be parameterized. Before .tagx files, we had
to
write a new tag in Java code to get parameterization. Doable, but
hardly as flexible.
Now in JSF, we have the same problem. Again, we can include stuff
(don't forget to use subview / though), but this is not
parameterizable. And we don't see a way to use .tagx files with JSF,
since we cannot mix JSP EL with JSF EL.
We would want to write the following myTag.tagx file:
?xml version=1.0 encoding=ISO-8859-1 ?
jsp:root xmlns:jsp=http://java.sun.com/JSP/Page; version=2.0
xmlns:h=http://java.sun.com/jsf/html;
jsp:directive.attribute name=handler type=java.lang.Object
required=true /
jsp:directive.attribute name=propertyName
type=java.lang.String
required=true /
h:outputText id=${propertyName}_label
value=#{handler[propertyName + 'Label']} /
h:inputText id=${propertyName} value
=#{handler[propertyName]} /
h:message id=${propertyName}_messages for=${propertyName} /
/jsp:root
and use it in the calling page as
q:myTag handler=#{myHandler} propertyName=myProperty /
The above sadly doesn't work. To start with, it wouldn't access the
managed bean facility.

Re: Problem with commandButton and required form fields
Gary, It seems like a good idea, but there are still some gotchas. There's no guarantee that the CommandButton's ActionEvent will be broadcast after the ValueChangeEvent from the UIInput. The value bindings also won't be performed since those happen in the update model phase. So, it'll help somewhat so long as you only directly read the values from the component. That's a step up from reading the form request values. Probably the best that can be done in the current JSF model. -Mike On 8/4/05, Gary VanMatre [EMAIL PROTECTED] wrote: I don't have any answers yet, but I'm having the same issue.

Re: Re: Problem with commandButton and required form fields
I was thinking of a similar solution. Open a new window with a new form, and move everything that's on the tabbed view to this popup panel. Have this triggered with a control on the first form. I don't know much javascript, but I think this is possible. On 8/5/05, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: I had a similar problem. I use UIInput components with NO value binding. Instead the components have a valueChangedListern (function) of a bean. So the values are added there internally. Setting immediate=true on the input components helps, but if you have serveral parts of a form, e.g. a second add button and input fields you are getting into troubles again. One solution is to split the form. But you would lose all other entered values and if client state saving is on you get much overhead. To solve the validation issue I have created a component to simulate a partial form submit (or better partial validation). With this component I can divide the form ito serveral parts where the validation and update model phase is only invoked on the components if a command component was clicked of this part. Maybe this would help you, too?

I agree. I considered implementing a page-scoped Managed Bean

Re: Help with DataScroller
From my limited use of DataScroller, it's simply a decorator.
You design as if it doesn't exist (ie, work everything through your DataTable).
Then you stick a couple DataScroller components on your page to modify
what's actually rendered and displayed, and add a rows parameter to
dataTable.

Re: Help with DataScroller
This might not be an issue with DataScroller or Datatable, but instead
is just a scoping issue with your table backing data.
Is your data still there after you process a second request? If
you're only accessing it in a request-scoped bean, then it's gone
afterwards. A quick way to check is to set the bean to
session-scoped. If that's the case, you'll probably want to use the
x:saveState component to preserve your data between requests.

It correctly displays the first page of the data table. The scrollers show
that I have 2 pages with a total of 14 entries and It is currently
displaying 10/14 of the entries. When I click to display the next page

Re: Saving state with custom UIComponents
Does your custom component have any state to save?

Re: Saving state with custom UIComponents
What both Craig and I are saying is that if you do nothing with state
saving for a component, by default you'll inherit state saving code
for your children.
If you define state saving code for your component, then you simply
call super.saveState()/restoreState() (like t:aliasBean and
t:saveState) in order to inherit this behavior.
What you've described below should work to my limited knowledge.
I've done something similar in the past, and it's worked for me.
However I created the children in the Component's constructor:
public RowAndColumnRelationshipsHtmlDataTable()
{
super();
Application app = getFacesContext().getApplication();
// If this is the first time we've shown the page, create the
children and facets.
boolean isInitialRequest = getFacesContext().getRenderResponse();
if (isInitialRequest)
{
addChildrenAndFacets();
}
}

I simplify my scenario - When the page is first requested, the tag handler
is instantiated and setProperties is called. In setProperties I am giving
the UIComponent an HtmlInputText child, passing 'foo' to
HtmlInputText.setValue(). An input text box with 'foo' is rendered.
Because classic tags are recycled, the tag handler is not instantiated on
subsequent page requests, setProperties is not called, and 'foo' is lost. A
blank input text box is rendered.
Perhaps this is a better question: what, if anything, must my UIComponent (a
direct decendant of UIComponentBase) do to insure the state of it's child is
saved?
As long as you either:
* Don't override the saveState() and restoreState() methods, or
* Call super.saveState() and super.restoreState() appropriately.
Still missing something. Looking at
myfaces/custom/aliasbean/AliasBean.java, saveState and
restoreState both call the super.saveState and super.restoreState . I
imagined component persistence to be the opposite - something that is called
on the root of the UIComponent tree and cascaded down to every leaf. If
such a chain reaction were to start from the leaves, wouldn't those
components higher up in the hierarchy be saved and restored more than once?
I haven't overidden saveState() or restoreState() ... this time.
I am not calling super.saveState() or super.restoreState() ... this time.
On past occastions, I have done both ;)

You can look at using request-scoped beans and the x:saveState component.
The x:saveState component will preserve a target (like your bean) so

Have your dataTable binding point to a getter method that combines the
three lists into one.

Re: JSF Specs issue: Custom error message for required fields
Alexander Jesse and I have just finished a component that will allow you to use a required validator rather than the required attribute. Lucky you! :) Basically, it's a standard validator, and a requiredValidatorChecker/ component that you add to the bottom of your form. The component goes through the component tree at the apply-request-value and decode value phases and runs the requiredValidator validator on all EditValueHolders that contain one as appropriate. It works great with MyFaces, but I don't know how it'll work with other JSF implementations. MyFaces runs it after it runs all other validators (since it's the last element on the form) and that's not behavior that's guaranteed. I'll probably commit something to sourceforge.net.jsf-comp in an hour or so. And yes, future implementations of JSF should dump the required attribute and make it a standard validator. However, there's going to be issues to be issues with validators that can't handle null or empty values. -Mike On 8/12/05, Marc Fonteijn [EMAIL PROTECTED] wrote: I'm looking for ways to assign a specific error message for required fields. Setting the javax.faces.component.UIInput.REQUIRED isn't a solution because I want a specific message for different fields. I thought of implementing an custom validator (method) and doing my own required check instead of using the required=true tag. Unfortunately this is stated in section 3.5.5 in the JSF Specification 1.1: Unless otherwise specified, components with a null local value cause the validation checking by this Validator to be skipped. If a component should be required to have a non-null value, a component attribute with the name required and the value true must be added to the component in order to enforce this rule. My conclusion is that the only way to enable this behaviour whould be to overwrite the validate method in UIInput in an custom component. You can see what that leads to, you'd have to make a custom implementation of every component that extends UIInput. Real solutions to this issue: - Make the default validation behaviour of UIInput optional in order to be able to write a custom validator that does the empty/null checking. - Implement an additional attribute on UIInput requiredMessage=.

x:saveState solves many problems by letting you
save the
state of a
request scope bean between requests. That is, it
feels like
having a
session scope bean as long as you need it. But
you don't
need to worry
about cluttering the session with unused
data, As soon as
you leave
the pages containing the x.savestate, the object
is removed.
We are using x.savestate all over our website,

reduced the
number of session scope beans to one. That is the
object
holding the

Re: x:dataScroller ArithmeticException
My guess is your backing bean containing your table data is in request

You can probably verify that this is the issue by temporarily adding
it in as session scope.

I'm not sure if this is an issue with MyFaces or with how I am doing
what I am doing or what. I have a very simple page with a a

That is to say, not navigating to a seperate page. I have it setup
with an edit button for each item and when that button is pressed I
render inputText components and an update button for the associated
row. This works.
The problem is that the update button's actionListener method binding
isn't working. When I press the update button, nothing happens. The
update(ActionEvent event) method is never called. It doesn't matter
if the bean is in the session or request. It just doesn't call the
method. I have stripped the code down to the simplest working example
that demonstrates this problem which I will post below. As it is
right now, I am merely showing and hiding the update/edit buttons.
When I press Edit the edit method is being called and the update
button is rendered where the edit button is now not rendered. If I
hit update button, the update method is never called and the edit
button is displayed again, hiding the update button. I realize that
with each button press a new request is being sent to the server.
However, it JSF is supposed to save the state of the bean for
actionListeners since it does not navigate from the page. However, I
don't believe this is working correctly. Any ideas? Thanks.

Re: method binding not working correctly
Some things to try:
What happens if you use an h:commandButton instead?
What happens if you dump the render statement?
Is #{not categoryAdmin.updateMode} legal? I've always used ! to this point.

Re: method binding not working correctly
The difference is that showNext doesn't depend on values in the
request-scoped bean.
It depends on values in the component tree (which is the same as
adding a value to the component tree using t:saveState).

However, if you'll notice, the bean is in request scope. There are

Re: method binding not working correctly
Yeah, it's really kinda strange that JSF didn't ship with a component
tree scope. All the components fall into this scope automatically,
so it's a bit silly that the backing beans can't be configured the
same way. On the other hand, t:saveState is incredibly flexible, and
we might not have seen that component developed if there had been a
component scope.

add some f:param attributes to the request.
Unfortunately, it doesn't seem to be a matter of just pointing the
javascript at the new UICommand. Is there something different I need
to do to activate a JSF-backed link?
Thanks,
-Mike
Re: Displaying Error Messages
You can either use null to specify a global error message, or you can set a binding on your elementForm:elementTable
so that's it's available as a UIComponent element to your backing
bean. Once you've set up a binding, you can get the client
id that way.
h:dataTable id=elementTable
binding=#{page.elementTableUIComponent}
facesContext.addMessage(elementTableUIComponent.getClientId(facesContext),
new FacesMessage(...

Hi,
I'm trying to understand how to display error messages that are indication of some exception cases in the Backing Bean.
There is no validation involved, but I
would like to show up an error message telling the user that a Delete
action on the table row has failed.
I use the FacesContext.addMessage - but
this takes the clientID as the argument. Is it always necessary to
harcode this id in the Backing Bean?
My code looks like this
h:form
id=elementForm
h:message
for=elementTable showDetail
=true showSummary=
true errorStyle=color:red
/
h
:dataTable id=
elementTable
……
And in the handler where the exception is thrown
catch (NoObjectFoundException exception)
{
FacesContext.getCurrentInstance().addMessage(elementForm:elementTable,
new FacesMessage(The Object does not exist .Unable to delete the
specified row. Please check the \n
+ logs for detailed error message !!! ));
return null;
}
Thanks

t:panelTabbedPane tab change seems to lose some values between tab pages switch
I have a two-panelTab panelTabbedPane in the middle of my input page. A t:panelTabbedPane tab change seems to lose some values external to the panelTabbedPane component between tab pages switch. For instance, my t:inputCalendar values above it get lost. And the value in an h:inputTextarea below it is sometimes lost, and sometimes shows back up when the tab is changed again. Sometimes the value is lost and doesn't reappear. (but it's completely external to the panelTabbedPane), depending on what other actions I trigger first. The h:inputText fields on the panelTabs do preserve values, however. I'm using today's MyFaces snapshot. -Mike
