Re: Checkbox event
Maybe a variation of the method proposed in
http://wiki.apache.org/myfaces/SubmitPageOnValueChange is useful to
you. You can have a hidden (with css) button that is clicked
automatically when you select the checkbox...

That was helpful. But, I would like to try some other way to utilize the power
of JSF :).
Is there a action event or valuechange event for checkbox. Any idea?
Thanks.

Hi,
I need to display a list box when a checkbox is clicked. I guess we need
to
implement OnSelect event for this purpose. Please, correct me here if I am
wrong.
Does anybody have some examples of using onSelect in the backing bean?.
Any help
is appreciated.
onSelect is a *client side* thing only. It is a normal HTML feature that
allows an arbitrary piece of scripting to be run in the browser. Nothing
to do with JSF at all.
You could implement what you want entirely on the client by ensuring
your page includes the listbox, but with its style set to display:none.
You should then be able to specify some script in the checkbox onSelect
attribute which finds that component and sets its style to visible. This
is really not JSF at all but that doesn't mean it's a bad solution.
Alternatively, I expect you could map the checkbox value to some boolean
value on a backing bean, and use the same value to control the
rendered attribute of the listbox.
h:selectBooleanCheckbox value=#{someBean.listBoxEnabled}/
h:selectManyListbox rendered=#{someBean.listBoxEnabled} ... /
The problem here is that you need some mechanism for submitting the
entire form back to the server when the checkbox value is changed so the
page can be regenerated.
Maybe you can use tomahawk's collapsible panel control instead of the
checkbox/listbox combination, and avoid the whole issue?

Simon

If this setting is set to false the user might have some strange effects if multiple browser windows are used.

I noticed that application is really slow already in first tests. It is not so bad in my Win laptop, but same application is really too much for 4 processor HP-itanium or 20 processor solaris machine (both few years old). Slowness is due to application's processor capacity usage in machines. Memory or garbage collection is not the issue. After while there is hardly any IDLE capasity and machines start to use plenty of SYS time. Response times are after that really long. This can be achieved just by running those 100 users once.

How to create component without binding?
Hello @all,
I would like to create dynamically inside a backing bean some components.
Looking around in the net I found only solutions that create a binding to a
component, for example:

This means that I always need an existing component like panelGroup for
creating with a binding some components.
How can I create dynamically components without using a binding (and in the
end an extra component)?

Draw dynamical columns in Datatable

Re: t:buffer as variable
Not being the definite expert on buffer, I would have said now.
'Buffer' buffers the output of the component rendering, afaik. Have
you tried aliasBean for achieving this? With aliasBean, the value is

when the aliasBean is closed.

Re: How to create component without binding?
You could add just the panelGroup (bound) and then add the components
as children of this panelGroup, so in the end you only have one
binding. Just use the method getChildren().add() of a component to add
children to that component,

Re: How to create component without binding?
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.

Javascript conflict between x:tree2 and x:inputCalendar

Specifically, as I reported on issue #MYFACES-743, I can't have x:tree2 with client-side toggling and x:calendar with popup, because the treeNavClick javascript function fails. Also, I noticed that the generated HTML body tag is malformed: body (with a space and a quotation mark) Could this be related to the problem?

Re: How to create component without binding?
This won't work - on every request, your setter will be called by the
JSF implementation. And on every request, you will get passed a new
component reference (except you do server side state saving, then this
might 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 should
easily find out what is going out then...

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

AW: MyFaces 1.1.1 - rendering of radiobuttons/labels

Hi all!
Doesn't the rendering of radiobuttons / labels work correctly?
Usually, you have to use the label element using the following approach
described in the SelfHTML 8.1 documentation:
label for=idNameLabel:/label
[Formelement] id=idName
But JSF renders something like this (it doesn't matter if I use
the standard
JSF HTML RenderKit taglib or Tomahawk):
labelinput type=radio name=_id0:_id2 value=someValue lang=de
title=someTitle class=daten /#160;someDescription/label
With this approach, you can't click on the label to select/deselect the
radiobutton, so the label just makes no sense.
Using the label to select/deselect the radiobutton would improve the
usability of the control.
Is this a bug?

AW: How to create component without binding?
First thanks for the many answers in just one hour :-)
Why do I need a binding to do this? If I need a binding to for example a
panelgroup this means that on the page the panelgroup gets rendered although

Lets assume I want to create dynamically several outputlinks. With a
panelgroup binding they are all inside a panelgroup. Why cannot I just hang

AW: How to create component without binding?
That sounds good ;)
How can I realize this?
f:view binding=my.backingbean
Like this?
Does a component exist that acts just like a container for other components
but itself doesn't get displayed? This way it would be possible to make a
binding to this component without the need to display the component.

This means that I always need an existing component like panelGroup

How can I create dynamically components without using a binding (and

Re: Calendar problems??
Hello!
And this is the reason why I created facelets issue too. Ok, waiting
for the Jacob Hookom comments. I'll quote You in Facelet's issue.

Hi,
we've had Thomas Spiegl look at problems with duplicate Ids and
facelets with the navMenu - and he has found no resolution (in the
limited time he had for this). It seems that several components are
now incompatible with facelets, and it just shows up cause I
implemented better errror handling. I am now controlling that for the
same parent, you can have the component with the same id only once.
I don't know what facelets would do to change this, really, but Thomas
was saying that somehow facelets seems to be creating components even
though they are already existing?
Please don't take everything I say here for granted, this is just what
I heard of from hearsay.

You are true, that's not desirable behaviour... can we see
the snippet
of the jsf code you are using?
Regards,
Bruno
2005/11/3, Matthias Kahlau [EMAIL PROTECTED]:
Hi all!
Doesn't the rendering of radiobuttons / labels work correctly?
Usually, you have to use the label element using the following
approach
described in the SelfHTML 8.1 documentation:
label for=idNameLabel:/label
[Formelement] id=idName
But JSF renders something like this (it doesn't matter if I use
the standard
JSF HTML RenderKit taglib or Tomahawk):
labelinput type=radio name=_id0:_id2 value=someValue
lang=de
title=someTitle class=daten /#160;someDescription/label
With this approach, you can't click on the label to
select/deselect
the
radiobutton, so the label just makes no sense.
Using the label to select/deselect the radiobutton would
improve the
usability of the control.
Is this a bug?
Regards,
Matthias

Re: Generic redirection screen
Hi,
I'm liking your method. I might build myself a function to do all that
all in one swoop. I guess the reason I started building multiple pages
rather than using something more clever liek this was because my
navigation rules all looked a bit boring when they all go to the same
page and seems like a waste of time putting them in :p. Thanks!

Mike Kienenberger wrote:
The general solution is to save the message in the session and display
it on a generic "display message" page.
The particular solution I'd use in this case would be to create a
request-scoped backing bean that holds the message to display, set the
message on the backing bean in my code, then use t:saveState on both
the display message page and the caller page to preserve that value
across the request.
I generally fetch/create the backing bean using this code, but maybe
there's a better way to do it.
ValueBinding binding =
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{backingBean}");
BackingBean backingBean = (BackingBean
)binding.getValue(FacesContext.getCurrentInstance());
backingBean.setValue(value);

Hi,
In past non-faces applications I have had a simple method in my
controlling servlet that would automatically display a screen with a
given message before redirecting to some given page. Something like this:
...
displayRedirect("Your order was completed successfully", "index.jsp");
In my JSF application I have navigation-rules for each outcome and a
sepparate view for each message. So for the example above i'd have
something like:
navigation-case
from-outcomecomplete/from-outcome
to-view-id/order_complete.xhtml/to-view-id
/navigation-case
The 'order_complete.xhtml' page would have the message "Your order was
completed successfully" and then a timed redirect to some other page.
I'm not completley stupid and am using a template (btw i'm using
facelets too) for all the redirection pages, but I'm still having to
create a page for each outcome.
Is there some nice way I can achieve this kind of behaviour without
making an individual view for all the messages?
Any comments welcome.

you can create a component subtree in your application, but at least you

What you want to do is do a binding for panelGroup
and then add children to this panelGroup - with this you can create
extra components.

public UIComponent getPanelGroup()
{
HtmlPanelGroup panelGroup = new HtmlPanelGroup();
panelGroup.getChildren().add(new HtmlInputText());
panelGroup.getChildren().add(new HtmlOutputText());

the h:panelGroup ... tag should render nothing but just the children

help needed regarding dynamic use of NavigationMenuItem
Hi
all
Can one be so kind and explain me what Im doing wrong. I must
not have understood something!
Need help.
What I would like is to recognize the menu node which has been pressed
by a user in my backing bean.
In the backing bean I construct the menu dynamically as shown in the
example and get it displayed correctly in the .jsp.
When I press a menu node the action function get called. So far OK.
But in that function I cannot identify the menu node which has been
pressed, must say that all menu nodes call the same action function.
The idea is to either grab the instance of the pressed menu node or to
find it in the value parameter, but no way .. neither I can identify and get
the node instance or have a value set in the value slot.
I would appreciate if one could tell me how to identify the selected
node.
Many thanks in advance.
Roland
Here a code snippet of the backing bean to show how I do it.
private SelectItem selectedNode;
public SelectItem getSelectedNode() {
return
selectedNode;
}
public
void setSelectedNode(SelectItem sNode) {
selectedNode
= sNode;
}
for (ListString menuItems : navMenuList) {
String menuIndex = (String)menuItems.get(0);
menuNode = new NavigationMenuItem((String)menuItems.get(1),
#{navTreeBean.actionSelectedNode}, null, false);
menuNode.setDescription(menuIndex); // misuse ID
menuNode.setValue(#{navTreeBean.selectedNode});
mainMenuNode.add(childHeader);
Return menu;
public String actionSelectedNode() {
ValueBinding xx = menuNode.getValueBinding(value);
System.out.println(the UIComponent found: + xx); // OK found the UIComponent
#{navTreeBean.menu}
ArrayListNavigationMenuItem updateBinding =
(ArrayListNavigationMenuItem) xx.getValue(context);
for (NavigationMenuItem ni : updateBinding){
System.out.println(the NavigationMenuItem value: + ni.getValue());
NavigationMenuItem node[] = ni.getNavigationMenuItems();
for (NavigationMenuItem nd : node)
System.out.println(the node: + nd.getValue() + id: +
nd.getDescription());
}
return page selected;
}
Out put of above iteration:
the NavigationMenuItem value: Users Maintenance
the node:#{navTreeBean.selectedNode} id: 2
the node:#{navTreeBean.selectedNode} id: 3
the node:#{navTreeBean.selectedNode} id: 4
the node:#{navTreeBean.selectedNode} id: 5
the NavigationMenuItem value: Resources Maintenance

Re: Trying to write my own component - AGAIN
I think that the best option to see how to implement a component is
directly check out the sources for the tomahawk/sandbox components.
Every component has the component, tag, and renderer implementation.
You can check the faces-config.xml file to see how this components are
registered and also the tld.
About your specific questions: you don't need any binding if your
component has everything in it (save/restore state, etc). Just pass
the model to the value attribute (I guess it should be something like
value=#{bean.graphicModel (without the getter)). Take a look at the
schedule component, as it accepts a custom model object.
The encodeBegin is optional as long as your component does not render
any children. When a component has children, the method encodeBegin is
called before and the encodeEnd afterwars. In your case, I guess you
only need the encodeEnd in your renderer object (recommended).

I think that the best option to see how to implement a component isdirectly check out the sources for the tomahawk/sandbox components.Every component has the component, tag, and renderer implementation.You can check the
faces-config.xml file to see how this components areregistered and also the tld.About your specific questions: you don't need any binding if yourcomponent has everything in it (save/restore state, etc). Just pass
the model to the value attribute (I guess it should be something likevalue=#{bean.graphicModel (without the getter)). Take a look at theschedule component, as it accepts a custom model object.The encodeBegin is optional as long as your component does not render
any children. When a component has children, the method encodeBegin iscalled before and the encodeEnd afterwars. In your case, I guess youonly need the encodeEnd in your renderer object (recommended).HTH,

RE: Checkbox event
If you really want the checkbox to invoke a back-end action, I believe
you'd have to do a short onselect JavaScript call to automatically
click a hidden h:commandLink component that itself is defined to
invoke the action. That's because actions are normally invoked only as
a result of clicking on a link or button.

Does anybody have some examples of using onSelect in the backing

is appreciated.
onSelect is a *client side* thing only. It is a normal HTML feature
that
allows an arbitrary piece of scripting to be run in the browser.
Nothing
to do with JSF at all.
You could implement what you want entirely on the client by ensuring
your page includes the listbox, but with its style set to
display:none.
You should then be able to specify some script in the checkbox
onSelect
attribute which finds that component and sets its style to visible.
This
is really not JSF at all but that doesn't mean it's a bad solution.
Alternatively, I expect you could map the checkbox value to some
boolean
value on a backing bean, and use the same value to control the
rendered attribute of the listbox.
h:selectBooleanCheckbox value=#{someBean.listBoxEnabled}/
h:selectManyListbox rendered=#{someBean.listBoxEnabled} ... /
The problem here is that you need some mechanism for submitting the
entire form back to the server when the checkbox value is changed so
the
page can be regenerated.
Maybe you can use tomahawk's collapsible panel control instead of the
checkbox/listbox combination, and avoid the whole issue?

Re: url query string parameters as input to JSF action - not possible??
So do I Sverker Abrahamsson wrote: HiT his is now more a conceptual discussion about JSF than specifically about MyFaces. As I understand it the scope of JSF was to make an application frontend framework which is not tied to http/html. In many aspects it does a good work, providing flexibility with it's rich event model and good separation of business logic and presentation. I like those parts a lot. However, it claims to be a framework for building web based applications, which means using HTTP for transport and HTML/ECMAScript for presentation (weather it's generated by jsp, xml+xslt or whatever). These are not perfect protocols, when they were designed nobody imagined they would have such inpact, but over the years people have been able to use these tools to make web-based applications with good usability. For doing so a number of common use cases or design patterns has evolved, normally GET is used when reading the state from the web application and POST is used when updating persistant state in the app. Of course there are variants where POST is used for other purposes but the most important is to be able to choose the method most suitable for the use case. I would say that GET requests are used in 99.99% of the cases (or more). Some pros about using GET over POST is that the resulting page is bookmarkable, it is possible to refer to it with an url and in most cases it's possible to use the browser back and forward buttons to navigate. Of course the application has to be designed with that in mind so that going back and forth in the application, or jumping right into it doesn't break anything but that's not so difficult. The mechanism for using GET requests in a web application is to encode the parameters in a query string in the url, it works best for reading the state of the application but can be used for submitting simple forms if care is taken that it does not break anything if the user use the back/forward button. POST is only better to use when submitting bigger forms or when Craig asked why people insist on using GET and constructing direct url's and the simple answer is that it is neccesary to get e.g. addressability like the the examples below shows: Hi, Craig. I found this interesting book on Amazon. Take a look at it on http://www.amazon.com/exec/obidos/tg/detail/-/0131463055/qid=1125490932/sr=8-1/ref=pd_bbs_1/102-6998912-0718528?v=glances=booksn=507846 http://www.amazon.com/exec/obidos/tg/detail/-/0131463055/qid=1125490932/sr=8-1/ref=pd_bbs_1/102-6998912-0718528?v=glances=booksn=507846 The JCP page for JSF 1.2 can be found at http://www.jcp.org/en/jsr/detail?id=252; You can see the status of your UPS shipment on http://wwwapps.ups.com/WebTracking/processInputRequest?HTMLVersion=5.0sort_by=statustracknums_displayed=5TypeOfInquiryNumber=Tloc=en_SEInquiryNumber1=1ZInquiryNumber2=InquiryNumber3=InquiryNumber4=InquiryNumber5=AgreeToTermsAndConditions=yestrack.x=33track.y=9 http://wwwapps.ups.com/WebTracking/processInputRequest?HTMLVersion=5.0sort_by=statustracknums_displayed=5TypeOfInquiryNumber=Tloc=en_SEInquiryNumber1=1ZInquiryNumber2=InquiryNumber3=InquiryNumber4=InquiryNumber5=AgreeToTermsAndConditions=yestrack.x=33track.y=9 These are just some examples, it's not possible to accomplish the same with POST. I can't refer to the result of a POST request with an URL. When designing a web-based application, the most important aspects are usability, scalability and maintainability. Usability definitly comes first, if it is poor nobody will use it (especially not if some competitor can provide the same functionality with better usability). There are tons of examples where projects have failed because of poor usability. That is the reality for people developing real applications for the real world. From time to time it appears academic work which in teory seams very nice but lack the connection to reality. Take e.g. the EJB spec as example, 1.x entity beans was not really usable, 2.x was better but not good. There was ideas about components which was assambled into applications, I don't know about anybody who used that functionality. Instead people started using xdoclets to generate those descriptor xml files. In parallell Hibernate emerged which was much better in sync with reality. We see the result now, EJB is essencially adopting to Hibernate model for persistence. Another example from a compleatly other domain; Voice over IP. When SIP and RTP was designed for VoIP it was not taken into account the use case where many users are behind NAT firewalls. I read the discussions and a big reason was that the authors thought NAT is bad and ugly (and that it was difficult to solve the problem). That resulted in that it took many years for VoIP to take off, it wasn't until some way for SIP telephony to get through the NAT firewall was developed that it became usable for the common user.

Re: Why does UIData access its grandchild components directly?
Oops!
Craig, thanks for catching this.
I looked into this right before going to sleep, and I didn't notice I
was looking at the javadocs for UIComponentBase.html#processDecodes
instead of UIData.html#processDecodes!
Yes, the javadocs for UIData clearly indicate that UIData is designed
to spec. Sorry for the misinformation.

Not actually true, or it couldn't have passed the TCK :-).
The
javadocs state Call the processDecodes() method of all facets and
children of this UIComponent, in the order determined by a call to
getFacetsAndChildren(). and that's not currently happening since
there are no calls to UIColumn.processDecodes().
That is superceded, for UIData, by the javadocs on that class itself.
Going back to the original question, the reason for UIData to deal with
grandchildren directly is explicity described in the javadocs quoted earlier
-- it allows UIData to perform the iteration over the underlying data model.
Among other things, that means UIData actually calls things like
processDecodes() *multiple* times on the same grandchildren ... once per
row. UIColumn doesn't get involved in this at all, other than being a
container for the contents of the grandchildren that will be rendered inside
that column zero or more times (indeed, it doesn't even have a renderer).
If you want a different design for managing iteration, you'll need to
design your own iteration component hierarchy.

UIData specializes the behavior of the processDecodes(),

For each of these methods, the UIData implementation must iterate over
each
row in the underlying data model, starting with the row identified by
the first

When iteration is complete, set the rowIndex property of this

UIColumn (extends UIComponentBase) is a component that represents a

Hi,
For an HTML table, much of the decoding process is in fact controlled
by
the components rather than the renderer.
In the class javax.faces.component.UIData, method
processColumnChildren (which is called by processDecodes) does this:
for (Iterator it = getChildren().iterator(); it.hasNext();)
{
UIComponent child = (UIComponent) it.next();
if (child instanceof UIColumn)
{
if (!child.isRendered())
{
//Column is not visible

{
UIComponent columnChild = (UIComponent) columnChildIter
.next();
process(context, columnChild, processAction);
}
}
}
And that last call to process them calls component.processDecodes,
which
delegates to the renderer as needed.
However this code means UIData is accessing its *grandchildren*
directly, rather than just its children. I don't believe this is very
nice OO design; UIData's children should be responsible for managing
their own children, ie the UIColumn class should be told to process
the
children rather than calling getChildren on it and manipulating those
directly.
And in my case, I'm trying to write a custom UIColumn class,

Re: custom error message
Sebastian, h:message2 is not a real component yet. It's just something that usrwagner was proposing. There's no easy solution to what you're asking for yet. JSF 1.2 has added a requiredMessage attribute that would do what you want. https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=81 h:message2 could in theory cycle through the list of messages and replace certain messages with a custom one. However, it'd be very hard to determine which message was the one you wanted to replace.

Re: Tree2
Client side toggling (clientside=true) would allow the user to click, click, click the tree to expand and contract nodes using only Javascript, with no HTTP calls required. Server side toggling (clientside=false) requires that the browser turn each click on the tree into individual HTTP calls, where the new tree is rendered by the server and returned to the client web browser after each click. Clientside is similar to tree in a Swing application. Serverside is a bit painful for the users in my opinion. But if your tree is very large, and you only want to load it when the user clicks on it, this may be your best option.

Hi,
the h:panelGroup ... tag should render nothing but just the children
if no style or styleClass attributes are present.
So
h:panelGroup binding=#{my.backingbean}
should do.

How can I realize this?

Does a component exist that acts just like a container for other
components
but itself doesn't get displayed? This way it would be possible to make a
binding to this component without the need to display the component.

Why do I need a binding to do this? If I need a binding to for example a
panelgroup this means that on the page the panelgroup gets rendered
although
I don't need (or want) it.
Lets assume I want to create dynamically several outputlinks. With a
panelgroup binding they are all inside a panelgroup. Why cannot I just
hang
the outputlinks in UIviewroot and skip all the binding stuff?

What you want to do is do a binding for panelGroup
and then add children to this panelGroup - with this you can create
extra components.
code snippet (not compiled except in my head ;):
public UIComponent getPanelGroup()
{
HtmlPanelGroup panelGroup = new HtmlPanelGroup();
panelGroup.getChildren().add(new HtmlInputText());
panelGroup.getChildren().add(new HtmlOutputText());
...
return panelGroup;
}

Re: Some notes of my loadtest results
comments inline... 1. We can now use STATE_SAVING_METHOD=server, and the back-button (and pop-up windows) will work correctly (e.g., when my pop-up window closes, my base window won't have forgotten its state)? yes you can do this now 2. Using STATE_SAVING_METHOD=server is faster and thus recommended? definitely. Since the state must not be transferred to the client which saves time. Just wondering what the current state of affairs is regarding the tradeoffs between server and client state saving method. +1 for this question..:) I have gone back and forth between the two and now am not at all sure which is recommended under what circumstances and why. I would also like to know, if MyFaces 1.1.1 is good enough or the answer given, whatver it may be, pertains to the latest nightly builds. only nightly builds supports multiple views if server state is used. -- Mathias
Re: Providing spring-like InitializingBean interface for JSF managed beans
I see that this functionality has already made it into JSF 1.2, using annotations. The interesting part of the implementation is that it also supports a destroy method using ServletRequestListener, HttpSessionListener, and ServletContextListener. http://weblogs.java.net/blog/edburns/archive/2005/08/using_ejb_annot.html https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=119 On 10/26/05, Mike Kienenberger [EMAIL PROTECTED] wrote: I've been reviewing open issues with my current application, and some of them seem to deal with using Spring. This is kind of frustrating because I'm finding that JSF managed beans do ALMOST everything I want without Spring, except for providing a InitializingBean.afterPropertiesSet() method call after a new bean's properties have been set. So after pondering it for a bit, it occurred to me that there's no reason why support for this interface (repackaged for MyFaces) can't be added to the org.apache.myfaces.el.VariableResolverImpl or to the org.apache.myfaces.config.ManagedBeanBuilder class. It seems to me that modifying one of the above classes to call the below code would provide this functionality in a backward-compatible way that does not affect the TCK. if (newBean instanceof InitializingBean) ((InitializingBean)newBean).afterPropertiesSet(); This could be done either as the last line in ManagedBeanBuilder.buildManagedBean() or right after the call to buildManagedBean() in VariableResolverImpl.resolveVariable. Unfortunately, I can't see a way to adding this functionality cleanly as a generic JSF tomahawk extension, so it would have to remain a MyFaces-only feature. Thoughts?
Usage of PanelNavigation2
Hi, We are using PanelNavigation2 to show a menu of actions. We have populated the menu and works pretty well. It gets rendered and it calls backing bean methods as expected. But since we create this menu dinamically in a backing bean, we can't define a diferent outcome for each menu entry in faces-config.xml. So, how can we know in the destination JSP which option has been selected?. Can we pass any kind of parameter to the NavigationMenuItem and retrieve it in the method given as action parameter?. Thank you very much for your attention, al.
panelTabbedPane h:commandLink problem
I believe that it is a known problem that panelTabbedPane will break any commandLinks found inside the tabs. It's because that bloody 'autoform' gets generated around the tabs AND their content. What I want to know is, has anyone modified panelTabbedPane to only wrap the form around the clickable top part of the tab? It seems like that would solve the problem, since the content of the tabs wouldn't be wrapped in the autoform anymore. I saw this mentioned in the mailing list back in April; is there really not a fix yet?

times when I press any of the submit buttons.

MyFaces 1.1.1 - problem with dataTable and selectOne menu contained in a panelTab
Hi! I have a strange problem using a selectOneMenu within a panelTab (MyFaces 1.1.1). The selectOneMenu is placed above a dataTable, which is also contained in the panelTab. Without the selectOneMenu, I can click on a commandLink in a table row to select one entry. But with the selectOneMenu placed above the dataTable, I can click on the links or the dataScroller below, and nothing happens. No request is initiated to update the page. (It doesn't matter if I use tags of the standard JSF HTML RenderKit Taglib or Tomahawk.) What's the problem with this composition, and how can I manage this? Regards, Matthias
collection size
I have a handler return a list of SelectItems that I use as:
h:selectOneMenu ...
f:selectItems value=#{handler.types}/
...
But, if there is only one item in the list then I'd like to change it
to plain output text (and a hidden input)
So, I tried
h:panelGroup rendered=#{length(handler.types) 1}
h:selectOneMenu ...
/h:panelGroup
h:panelGroup rendered=#{length(handler.types) == 1}
h:inputHidden rendered=true ...
/h:panelGroup
but that isn't valid expression syntax.
How do I get the size of my collection (List)?
Thanks,

Re: inputFileUpload using excessive amounts of memory
I have been unable to find the exact cause but I have managed to stop the problem for the moment and I dont have the time to muck around with it any longer. It seems to be that it was allocating memory for the maximum file size that could be uploaded. If I had the max upload size at 50mb, but a disk threshold of around 5mb, it would run out of memory, even for very small files. By putting the disk threshold to 0mb it seems to always use the disk and I dont get any memory problems at all, even uploading 80mb files with a VM memory size of 64mb (which should be possible of course). So i'm happy for the time being. I dont know if this is a problem in the way that the MultipartFilter operates or a problem with using the mutli-part filter in combination with facelets or some other issue. Has anyone successfully used the Tomahawk file upload component with Facelets? I'm running MyFaces 1.1.1 (with same-version of Tomahawk) and Facelets 1.0d. Thanks, -Robert.

I downloaded JProfiler and it has many nice screens but I cant seem to make it do anything usefull. I tried using NetBeans debugger to break on any ServletException or OutOfMemoryError and it didnt catch either :S. Any ideas of how I could track this thing down? Thanks, -Robert Martin Marinschek wrote: Sounds very interesting. Can you profile through what the extensions filter is doing? The question is when this amount of memory is built up, if in the extension filter or later in the JSF life-cycle, I can't imagine where this would be. regards, Martin On 11/3/05, Robert Parsons [EMAIL PROTECTED] wrote: Hi, Sorry to bother everyone again. I have been trying to use the file upload component of MyFaces (Tomahawk), but my JVM is using up an incredible amount of memory to process each upload request. With a max memory size of 64mb it (the server) would almost certainly run out of heap space. On 120mb I could upload the file but if I uploaded 2 in quick succession it would almost certainly run out. With 1GB of memory I could always upload a file, but uploading files in quick succession took the memory usage super high from 120mb,200mb,500mb! Oh and by the way these files were no more than 2mb each, and you didn't even have to upload a file to use up the memory, just submit the form. Sureley this much memory should not be need to upload such tiny files. Is this a problem with the upload component (or the extension filter) or is it something i'm doing wrong? In my web.xml the maximum upload size is set to 50mb and a use-the-disk threshold of 10mb. The exception see back from tomcat is: exception: javax.servlet.ServletException: Filter execution threw an exception org.apache.myfaces.component.html.util.MultipartFilter.doFilter(MultipartFilter.java:102) root cause: java.lang.OutOfMemoryError: Java heap space Any ideas?

Re: File upload, exceed limit
Should it possibly appear as if a normal validation exception? Have a fileSizeValidator? I dont really know how validators work, just a suggestion. Martin Marinschek wrote: That is an old problem we haven't resolved yet. What we should do is set a request parameter I think - and on decode, the fileUpload component checks this request parameter and adds a message. What do you think? regards, Martin On 11/3/05, Dave [EMAIL PROTECTED] wrote: I am using FileUpload.

Re: valueChangeBackListener ?
yes, that probably would have worked. however the business requirements changed at a meeting so now it isn't a problem ;) Original message Date: Wed, 2 Nov 2005 10:51:31 -0500 From: Mike Kienenberger [EMAIL PROTECTED] Subject: Re: valueChangeBackListener ? To: MyFaces Discussion users@myfaces.apache.org What about changing it to an actionListener and checking it yourself? http://wiki.apache.org/myfaces/SubmitPageOnValueChange I haven't used valueChangeListener, but it seems like a bug if it doesn't detect all changes.
