Hi folks!
Problem:
I wanna show a Link in a datatable if the user has a specific right
and if he hasn't I wanna show only text.
If I use the rendered tag the text wasn't shown if rendered = false.
Hi ya!
what about this? a command link is rendered only when the boolean
variable sessionScope.ucs.secGroup is set to true otherwhise an output
text is displayed.
h:commandLink value=UNLOCK action=#{odgPwdHandler.unlockUser}
rendered=#{ (sessionScope.ucs.secGroup) }
f:param name=uid value=#{result.userId}/
/h:commandLink
h:outputText value=UNLOCK rendered=#{(not sessionScope.ucs.secGroup)
}/
BTW you can embed this in a Datatable
cheers
fabio
So I tried to put an HtmlPanelGrid into my datatable with the
attribute: binding=#{row.testPanel} (row is the var for the rows...).
But it didn't work. I got error messages like this:
Error setting property 'testPanel' in bean of type null
What can I do except writing a custom component???

AW: Finding a component with a specific id
Hi!
You need the name/id of the form enclosing your component!
Then you can use the findComponent method in this way:
UIComponent table = facesContext.getViewRoot().findComponent(formId + : +
tableId);
Or you has a binding to your parentcomponent (f.e. form) and call the
finComponent method at the parentcomponent only with the tableId.
If you are using this method you must ensure that the tableId doesn't change!

Stefan

Betreff: Finding a component with a specific id
Hi,
From a custom renderer I need to be able to find a component with a
specific id.
Page:
o:colSelector tableId=table1 .../
t:dataTable id=table1 ...
..
/t:dataTable
From the renderer for the o:colSelector I've tried:
UIComponent table = facesContext.getViewRoot().findComponent(tableId);
UIComponent table = component.findComponent(tableId);
UIComponent table = component.findComponent(: + tableId);
but had no luck.
The table is enclosed in a subview named body, so the id actually gets
output as body:table1. I've tried all the above with that string too,
and no luck.
Any ideas how I should locate that table component by id??
[And BTW, is it possible for a component in a naming container to have
an id that is *not* prefixed by its NamingContainer parent's id?]
On a related note, looking at the source for UIComponent.findComponent,
I see it calls _ComponentUtils.findComponent which is as follows.
static UIComponent findComponent(UIComponent findBase, String id)
{
if (idsAreEqual(id,findBase))
{
return findBase;
}
for (Iterator it = findBase.getFacetsAndChildren();
it.hasNext(); )
{
UIComponent childOrFacet = (UIComponent)it.next();
if (!(childOrFacet instanceof NamingContainer))
{
UIComponent find = findComponent(childOrFacet, id);
if (find != null) return find;
}
else if (idsAreEqual(id,childOrFacet))
{
return childOrFacet;
}
}
return null;
}
What's the point of that instanceof NamingContainer? Why doesn't the
search recurse into NamingContainer children of findBase?
Thanks,
Simon
Re: inputCalendar javascript Error on IE

Dynamic tabs

Re: Comparable validation design
@attribute name: is there something like this in the RI 1.2? I think that yes, so maybe we should go with their name for this. @comparable: right, there is the interface name - I didn't think about that. But then the equalsValidator is named by the method it calls - so maybe we should take the method name here as well - compareToValidator or more simple compareValidator ? Forget about my suggestions if I start to enerve you - then just take the interface name ;) regards, Martin On 10/24/05, Mike Kienenberger [EMAIL PROTECTED] wrote: comparingValidator works for me. As Alexander pointed out, I used comparableValidator as a first guess because it works on any objects implementing Comparable. I don't see the need for comparingValidator to depend on the OptionalValidatorFramework, although the supporting boolean wrapping validator that Alexander proposed might share code with the OVF project. The OptionalValidatorFramework isn't quite ready yet. I'd say it's 95% done functionally, but there's still some more work that needs to be done to handle converters better. Now that we've got it functional, we have a lot of cleanup that remains. I'm also not happy with how the facelets integration was implemented, and I need to work out those details with the Facelets folks. Does anyone have a suggestion on the attribute name for specifying an optional identifier of the message as it is the message-files? This attribute would be a good tomahawk extension for all validators.

Re: PROBLEMS WITH TREE2
I don't think that the browser cache is the problem - if the browser would cache the html of the tree then you would also get the old (administrator's) tree displayed. Imho the problem is a session bean containing your tree data. You should destroy all session data when a user logs out. rosalba bochicchio wrote: I've probably found the trouble. I suppose it is a problem due to browser caching...I'll try to explain it: my web app is a management console. It's made up of a menu, which is a tree, a fix header and a content page. Whe I click on the nodes of the tree I want the content page to change. I can log in as simple user or Administrator. When I log in as Administrator I can see, as a menu, a tree made up of all the users of the console. Instead, when I log in as a simple user I can see anly myself. The behaviour is the following one: When I log in as simple user and the as Administrator, everything works fine. When I log in as Administrator and then as simple user, I get the problem I tried to describe in the previous message...that is, when clicking on the unique node of the tree I get the exception! I suppose the reason is that the browser caches the tree with the nodes related to all the user, and gets the exception when the node is made up of a single node...Do you think it's a possible reason? have you any suggestion to solve the question?

Yes, ARequestScopedObject implements Serializable.

Subject: How to use t:saveState ?
Hi,
I've been trying to use t:saveState without success. As far as I
can read in the wiki and in the examples, you just need to include a
t:saveState value=xxx/ in the JSP and the information will travel
to the client and back in the next request.
So I created 3 pages, test1, test2 and test3, each with a
t:saveState value=aRequestScopedObject/. In the backing bean I do
something like:
aRequestScopedObject = (ARequestScopedObject) getFacesContext()
.getApplication()
.createValueBinding(#{aRequestScopedObject})
.getValue(getFacesContext());
And then I set several properties on it.
Well, when I reach the test2 page _all changes_ are lost. Reading
the generated HTML I don't see anything at all related to the
saveState info in the form (!?)
Am I missing anything ?
Any comment would be really welcome. It seems to be very simple to
use, the only strange thing is that I'm using the Sun RI + Tomahawk.
Thanks in advance,
- Juancho

Dynamic menu using navigationMenuItems and NavigationMenuItem
Hi all In my backing bean Im able to dynamically construct the menu tree and it display well on my index.jsp page. The ugly is that I cannot really recognise which menu item has been pressed by the user. I know that a function call is made to the function passed in the action argument. I can for sure give the same function name to called for each menu node, but how do I recognise which menu node have been selected? If I assign different functions to be called for each menu node I loose the dynamism of the menu solution, as I would have to touch the Java code each time a menu node is added or removed. Might be I did not understand it right and would appreciate any tips and hints or an idea how to get around, in JMHO, this restriction. Thanks for all inputs and helps. Cheers Roland

Hi *, please add your company's name on http://wiki.apache.org/myfaces/Companies_Using_MyFaces if you use MyFaces in one of your applications at these companies. The list starts looking impressive - good idea, Bruno ;) regards, Martin
valueChangeListener - inputText - Which method is correct?
Ive seen 3 different examples of using the valueChangeListener
attribute.
Ive seen
Example 1:
JSP
h:inputText value=foo f:valueChangeListener type=com.jsf.MyValueChangeListener//h:inputText
CODE
public class MyValueChangeListener implements ValueChangeListener { public MyValueChangeListener() { } public void processValueChange(ValueChangeEvent vce) throws AbortProcessingException { System.out.println(A value has changed!); }}
Example 2:
JSP
h:inputText id=partNumber value=#{nonConformingMaterial.partNumber} required=true
valueChangeListener=#{nonConformingMaterial.changeEvent}
onclick=submit()
immediate=true
/
Example 3:
JSP
s:inputSuggestAjax suggestedItemsMethod=#{inputSuggestAjax.getItems} styleLocation= /
I like example 3, very sexy. (see http://irian.at/myfaces-sandbox/inputSuggestAjax.jsf)
But its not what I need in my application.
What I need is, when an inputText is filled in, an action is
called so that another inputText field is automatically filled in.
I presume that I should be trying to get example 1 working. Would
you agree?
Re: error with sandbox ajax component on
It really looks as if you would use an older version of the implementation.

Problem with NavigationMenuItem
Hi,
I am trying to construct a menu in my backing bean, and want to
display it with jscookmenu.
I can construct the menu, and jscookmenu can display it.
Problem is, I couln't figure out how I can assign an action to the
NavigationMenuItem.
Here is how I construct the NavigationMenuItem:
menu[0] = new NavigationMenuItem(Logout,#{UserBean.logout}, null, false);
When I click on this menu item on the resulting page, the page reloads
instead of running the logout method in my backing bean.
I tried constructing the menu statically in the jsp page, but I get
the same effect:
t:navigationMenuItem id=menu1_1 itemLabel=Logout
action=#{UserBean.logout} /
Does the NavigationMenuItem support this kind of action mapping? If
so, is the action syntax different than that of the CommandButton?
(When I try with a CommandButton, the logout method is called:
h:commandButton value=Logout action=#{UserBean.logout}/h:commandButton
)
Thank you,
Turgay Zengin
RE: valueChangeListener - inputText - Which method is correct?
Thanks Bruno. Great links.
The spec for h:inputText states that it has the MethodBinding attribute
valueChangeListener.
So if I set this as...
h:inputText id=name value=#{ncm.name} required=true
valueChangeListener=#{ncm.changeEvent} /
Should it not call my method in the ncm class?
public void changeEvent(ValueChangeEvent event) {
String partNo = ((String)event.getNewValue());
}
Or am I missing something?

Re: Dynamic tabs
Any ideas about this spreadsheet-like stuff using MyFaces?2005/10/25, Enrique Medina [EMAIL PROTECTED]: Hi, In my application I need to present the user with something similar to an Excel document, i.e., several tabs (Excel sheets) and the possibility to edit tabular data (using a datatable) for every tab. Has anyone tried something like this? I would really appreciate to hear about your approaches.
Re: valueChangeListener - inputText - Which method is correct?
Yes, but the ValueChangeEvent will be processed in the Process
Validations phase, after submitting the form. So if you want to change
the value of the other inputText when the first changes, you need to
submit the form (technique #1). Otherwise, you can use javascript if
it is an option to you (if you don't have to process the form).
Hope it is clear now,

Re: Design question: how best to pass query from search-form to result-page
you also could use t:saveState on your backing bean instead of putting it into the session ;-) Rick Gruber-Riemer wrote: Hi I would like to know what the best practice is to pass a query from a search-form to a results page. With this a mean page A with some form elements to search for records in a database and page B showning a table of results with all matches. I can come up with the following 5 alternatives: * [A]: A.jsp and B.jsp refer to the same Backing Bean, which has session scope. So when B.jsp is called and the table rendered, the Backing Bean has directly access to the search form fields and can use these to submit a query in a DAO. * [B]: A.jsp and B.jsp have Backing Beans A.java and B.java in request scope. A.java puts the form elements within its action method into a Map, which is stored in either the request or the session. B.java reads the Map from either session or request and uses them to submit a query in a DAO. * [C]: pages and beans like [B]. But A.java's action method actually makes query in DAO and then puts the result in session or request. * [D]: This time in A.java's action method FacesContext is used to get an instance of B.java and set the form parameters with getters/setters, such that in the render phase of b.jsp a query can be made against a DAO. * [E]: In A.java's action method submit the form parameters to a DAO method, which returns a query string. This is then set into a session parameter. In B.java get the query string from the session parameter and use it then to submit a query in the DAO. The beauty of this would be that the concrete DAO implementation would generate the relevant query, such that it would be transparent for the Backing Bean and a Business Delegat whether we use a Hibernate implementation or plain SQL or JDO ... And the query string does not use a lot of memory in the session :-). Plus a select count(*) in the DAO already when getting the query string in A.java could reveal, whether the user has to be more precice as the query would return to many records (configurable). Pros/cons: * [A]: Positive: easy to implement. Negative: session scope and results potentially hanging around in session (e.g. for simple pager). * [B]: Positive: request scope. Negative: as with [A] the Map gets some logic with field names that need to be maintained. * [C]: Positive: easy to implement. Negative: As with [A] there can be problems if using request parameters in portlets (as far as I know). Results can be big and somehow should be nullified in session as soon as pointer is set in B.java. * [D]: Negative: not really an improvement over [A]; I do not like to play with BackingBeans in FacesContext (- session vs. request scope?) * [E]: Positive: I just like it ;-) Any comments?
RE: valueChangeListener - inputText - Which method is correct?
Title: RE: valueChangeListener - inputText - Which method is correct?
The spec says ...
MethodBinding representing a value change listener method that will be notified when a new value has been set for this input component.
I was left with the impression from this that when the field's value changes then the method would get called. Not when the form is submitted.
I dont need to process the form. I'm in the situation where a person types in a part number, and the several other fields are auto populated from that value (i.e. the part description manufacture). The form is not submitted thought till they have entered a load of other details.
I guess I can look at getting some _javascript_ to do this. But its a shame there isnt a method for this in MyFaces.
I see that I can write something like this
h:selectBooleanCheckbox
valueChangeListener=#{resumeBean.changeColorMode}
>
immediate=true/
But this results in the form being submitted error messages being displayed because of fields not filled. This would confuse the user, since
They've not pressed the submit button yet.

RE: Finding a component with a specific id
Have you tried putting the colSelector after the datatable? It sounds
like the view does not yet contain the table. I thought myFaces had
similar issues with the DataScroller in ealier versions (maybe still
do). Maybe take a look on how they handled?
Of course, just a guess.

Subject: Finding a component with a specific id
Hi,
From a custom renderer I need to be able to find a component with a
specific id.
Page:
o:colSelector tableId=table1 .../
t:dataTable id=table1 ...
..
/t:dataTable
From the renderer for the o:colSelector I've tried:
UIComponent table =
facesContext.getViewRoot().findComponent(tableId);
UIComponent table = component.findComponent(tableId);
UIComponent table = component.findComponent(: + tableId); but had
no luck.
The table is enclosed in a subview named body, so the id actually gets
output as body:table1. I've tried all the above with that string too,
and no luck.
Any ideas how I should locate that table component by id??
[And BTW, is it possible for a component in a naming container to have
an id that is *not* prefixed by its NamingContainer parent's id?]
On a related note, looking at the source for UIComponent.findComponent,
I see it calls _ComponentUtils.findComponent which is as follows.
static UIComponent findComponent(UIComponent findBase, String id)
{
if (idsAreEqual(id,findBase))
{
return findBase;
}
for (Iterator it = findBase.getFacetsAndChildren();
it.hasNext(); )
{
UIComponent childOrFacet = (UIComponent)it.next();
if (!(childOrFacet instanceof NamingContainer))
{
UIComponent find = findComponent(childOrFacet, id);
if (find != null) return find;
}
else if (idsAreEqual(id,childOrFacet))
{
return childOrFacet;
}
}
return null;
}
What's the point of that instanceof NamingContainer? Why doesn't the
search recurse into NamingContainer children of findBase?
Thanks,
Simon

Re: command button for link
The parameter action=somewhere is referring to an from-outcome
defined in your faces-config.xml, therefore you can't directly address
your regpart.jsf.
A navigation rule like
navigation-rule
from-view-id*/from-view-id
navigation-case
from-outcomeregpart/from-outcome
to-view-id/regpart.jsf/to-view-id
redirect /
/navigation-case
/navigation-rule
with an commandButton like
h:commandButton action=regpart value=your text/
should work.

It does work. Changing the STATE_SAVING_METHOD to client as you

Subject: How to use t:saveState ?
Hi,
I've been trying to use t:saveState without success. As far as I
can read in the wiki and in the examples, you just need to include a
t:saveState value=xxx/ in the JSP and the information will travel
to the client and back in the next request.
So I created 3 pages, test1, test2 and test3, each with a
t:saveState value=aRequestScopedObject/. In the backing bean I do
something like:
aRequestScopedObject = (ARequestScopedObject) getFacesContext()
.getApplication()
.createValueBinding(#{aRequestScopedObject})
.getValue(getFacesContext());
And then I set several properties on it.
Well, when I reach the test2 page _all changes_ are lost. Reading
the generated HTML I don't see anything at all related to the
saveState info in the form (!?)
Am I missing anything ?
Any comment would be really welcome. It seems to be very simple to
use, the only strange thing is that I'm using the Sun RI + Tomahawk.
Thanks in advance,
- Juancho

RE: x:commandLink and onClick
Oh! That's a good idea. However, that presents another problem for my
page. By way of some background, I'm using a dataTable to build a list
of upcoming conferences. The final column contains two links inside,
Edit and Delete. The Edit navigates to a detail page, while the
delete would obviously remove the record and reload the page. I also
have an Add Conference button outside of the table. Using the
onSubmit attribute would prompt for confirmation no matter what control
is activated. Perhaps I should just use commandButtons instead of
commandLinks and avoid the issue altogether.

Subject: How to use t:saveState ?
Hi,
I've been trying to use t:saveState without success. As far as I
can read in the wiki and in the examples, you just need to include a
t:saveState value=xxx/ in the JSP and the information will
travel
to the client and back in the next request.
So I created 3 pages, test1, test2 and test3, each with a
t:saveState value=aRequestScopedObject/. In the backing bean I
do
something like:
aRequestScopedObject = (ARequestScopedObject) getFacesContext()
.getApplication()
.createValueBinding(#{aRequestScopedObject})
.getValue(getFacesContext());
And then I set several properties on it.
Well, when I reach the test2 page _all changes_ are lost.
Reading
the generated HTML I don't see anything at all related to the
saveState info in the form (!?)
Am I missing anything ?
Any comment would be really welcome. It seems to be very simple
to
use, the only strange thing is that I'm using the Sun RI +
Tomahawk.
Thanks in advance,
- Juancho

Re: Validating a DataTable
My guess is no. One thing you could do is add a validator to some other EditableValueHolder component on your page, but have the validator check the dataTable constraint instead of the EVH component. You could create a for attribute (like t:dataScroller or t:equalsValidator) that points to the correct component to check. It might be worthwhile to create a globalValidationHolder component that simply holds validators like this, implements EVH, and does nothing else. Another option is to perform the check in your action methods. The downside to this is that you'd have to check it for every possible action or actionlistener.

Subject: Finding a component with a specific id
Hi,
From a custom renderer I need to be able to find a component with a
specific id.
Page:
o:colSelector tableId=table1 .../
t:dataTable id=table1 ...
..
/t:dataTable
From the renderer for the o:colSelector I've tried:
UIComponent table =
facesContext.getViewRoot().findComponent(tableId);
UIComponent table = component.findComponent(tableId);
UIComponent table = component.findComponent(: + tableId);
but had no luck.
The table is enclosed in a subview named body, so the id actually gets
output as body:table1. I've tried all the above with that string too,
and no luck.
Any ideas how I should locate that table component by id??
[And BTW, is it possible for a component in a naming container to have
an id that is *not* prefixed by its NamingContainer parent's id?]
On a related note, looking at the source for UIComponent.findComponent,
I see it calls _ComponentUtils.findComponent which is as follows.
static UIComponent findComponent(UIComponent findBase, String id)
{
if (idsAreEqual(id,findBase))
{
return findBase;
}
for (Iterator it = findBase.getFacetsAndChildren();
it.hasNext(); )
{
UIComponent childOrFacet = (UIComponent)it.next();
if (!(childOrFacet instanceof NamingContainer))
{
UIComponent find = findComponent(childOrFacet, id);
if (find != null) return find;
}
else if (idsAreEqual(id,childOrFacet))
{
return childOrFacet;
}
}
return null;
}
What's the point of that instanceof NamingContainer? Why doesn't the
search recurse into NamingContainer children of findBase?
Thanks,
Simon
Re: valueChangeListener - inputText - Which method is correct?
JSF is server-side processing. So anything that JSF does requires a
form submit.
You can try marking the input field and the triggering action (not
actionListener) as immediate. That should cause it to validate and
execute your action before the other fields. I think this will also
short-circuit the rest of the JSF processing, and you won't get
validation errors for other fields. I could be wrong, though.
However, you're also going to short-circuit the model-update phase, so
you may find this makes it difficult to accomplish your goal of
reading values and updating values on components.
The way I've handled this in my own project is to use javascript to
force an immediate submit, and create an optional validation framework
(OVF) that allows the full JSF lifecycle to execute even though some
components fail to validate.
The example below (combined with the OVF) would submit the change, but
not perform any validation or model updates for components with
optional validators. For my own use case, I want the validation
errors to show up, but not stop the lifecyle, so it reads soft
instead of none in the example code. This allows components that
pass validation to be available after the updateModel phase.
Unfortunately, it's still an all or nothing situation for components
marked as optionally-validating. On my todo list is to allow you to
dynamically group components, depending on the control causing the
action, so that some components are non-validating, some are
soft-validating (generate error messages, but don't short-circuit the
lifecycle) and some are hard-validating (standard JSF behavior where a
validation error ends the current lifecyle). I haven't decided
whether the best implementation for this is to specify controls by id
(soft=inputText1,inputText2, hard=inputText3, none=inputText4)
or by somehow specifying groups on the optional validators.
Quite honestly, if you have the ability to do this all in pure
javascript, that's the easier solution. Doing conditional validation,
especially when you need some components to be valid afterward, is
hard in JSF.

I was left with the impression from this that when the field's value changes
then the method would get called. Not when the form is submitted.
I don't need to process the form. I'm in the situation where a person types
in a part number, and the several other fields are auto populated from
that value (i.e. the part description manufacture). The form is not
submitted thought till they have entered a load of other details.
I guess I can look at getting some javascript to do this. But it's a shame
there isn't a method for this in MyFaces.
I see that I can write something like this…
h:selectBooleanCheckbox
valueChangeListener=#{resumeBean.changeColorMode}
onchange=submit()
immediate=true/
But this results in the form being submitted error messages being
displayed because of fields not filled. This would confuse the user, since
They've not pressed the submit button yet.

Yes, but the ValueChangeEvent will be processed in the Process

the value of the other inputText when the first changes, you need to
submit the form (technique #1). Otherwise, you can use javascript if
it is an option to you (if you don't have to process the form).

Re: Validating a DataTable
Hi Volker! I'm currently implementing a Web-GUI for an application generated from a UML-meta-model. To model a 1:n or m:n relationship (general associations or compositions), I use a table, and additional Add- and Remove buttons. Now there are constraints on the association ends, like X must have at least a and at most b relations to Y, when committing. Thus the table needs to be validated. I went for Mike's approach, generating a hidden input field below each table and a error message above. In the bean I needed to generate an additional getXXXSize method, because I didn't know how to reference the size method of the list using EL. It works :-) Thanks everyone!

Re: Comparable validation design
A few more questions. 1) What should happen if the compared values do not implement Comparable and no Comparable is provided? Right now, it's passively passing validation. I wonder if it should throw a FacesException (not ValidationException) instead? 2) If either the foreign component value or the parent component value are null, perform no validation? This is going to happen by default if the parent component value is null since JSF won't execute validators in that case. We can't validate if: a) value is null and foreign value is null b) value is null and foreign value is not null. We could try to validate if c) value is not null and foreign value is null d) value is not null and foreign value is not null For consistency, I'd say we'd do the same thing for the foreign key, and only try to validate for case d).

How to handle double posting problems
Hi,
I am new to jsf and just beginning to put together some
pages. I am playing with a form that has an event listener on a selection list,
the form refreshes depending on the selection. I discovered that if I click too
fast jsf will throw the following exception:
01:07:42,794 ERROR [FacesServlet]:253 -
Servlet.service() for servlet FacesServlet threw exception
javax.faces.el.EvaluationException: Cannot get value for _expression_
'#{userBean.userIdsList}'
What is the best way to handle this situation?
Many thanks in advance.

RE: AW: FileDownload capability?
In earlier examples, one had to call response.setContentLength() with
the number of bytes being passed. I have the following questions
regarding this:
1. What are the consequences if I get the length wrong? Does it have to
be exact?
2. Can the setContentLength() be called after I have done all the
writes, or must it be done before the writes? If I can call it
beforehand, then I can compute the length as I go. Otherwise, it will
be more difficult.

It is actualy much easier in JSF. You just need to have an action method
in
a (managed) bean, like this:
public String downloadFile() {
FacesContext facesContext = FacesContext.getCurrentInstance();
if (!facesContext.getResponseComplete()) {
String fileName = myfile.pdf;
ServletContext servletContext = (ServletContext)
facesContext.getExternalContext().getContext();
String contentType =
servletContext.getMimeType(fileName);
HttpServletResponse response = (HttpServletResponse)
facesContext.getExternalContext().getResponse();
response.setContentType(contentType);
response.setHeader(Content-Disposition,
attachment;filename=\ + fileName + \);
try {
InputStream in = /* get your data */;
ServletOutputStream out =
response.getOutputStream();
byte[] buf = new byte[512];
int bytesRead;
while ((bytesRead = in.read(buf, 0, bufSize)) !=
-1)
{
out.write(buf, 0, bytesRead);
}
out.flush();
facesContext.responseComplete();
} catch (IOException e) {
throw new RuntimeException(e);
}
}
return null;
}
Then you can simply call the method from a commandLink or commandButton
h:commandLink action=#{yourBean.downloadFile}
h:outputText value=download /
/h:commandLink

but you basically set the header mimetype to either your filetype or

RE: AW: FileDownload capability?
I think I have most of the answers to my own questions, after consulting
the O'Reilly book Java Servlet Programming:
1. The response, if set, has to be exact. However, it does not have to
be set. Using it allows Servlets to be able to take advantage of
persistent connections, if available.
2. It must be set before sending the response body.
So, given this, does (2) above imply that, if done, setting the length
has to precede the first write? Or it just has to be done before
calling responseComplete()?
- Brendan
P.S. I realize this is more of a Servlet question than a MyFaces
question. Sorry about that.

Re: AW: FileDownload capability?
It depends on the browser and container, but ignore it at your own risk.
The safest solution is to set the content length to the exact size
before writing any data to the response.
If the data is being computed on the fly, then write your data to a
ByteArrayOutputStream first, then use byte data[] =
ByteArrayOutputStream.toByteArray() to get something to send to the
response.
Here's an example of what might happen if you don't.

Re: SelectOneCountry, skip validation?
For simple situations (like only one occurrance of the above on a page), you can just set the UICommand and the UIInput components both to immediate=true Just remember that you're not skipping the validation phase. You're short-circuiting the lifecycle before validation gets executed, so it goes Restore View - Apply Values - process immediate values and actions - Render Response There's no process-validation, update-model, or invoke-app phases executed. -Mike On 10/25/05, Bruno Aranda [EMAIL PROTECTED] wrote: Dave, take a look at http://wiki.apache.org/myfaces/SubmitPageOnValueChange , you can click a hidden button with the immediate attribute set to true, Regards, Bruno 2005/10/25, Dave [EMAIL PROTECTED]: The form is not submitted by clicking a button, but using event onchange.

RE: AW: FileDownload capability?
Yes, well I can certainly understand why setting content length to zero
(as was the case in in the link you sent) would be problematic.
Thanks for your help!

It depends on the browser and container, but ignore it at your own risk.
The safest solution is to set the content length to the exact size
before writing any data to the response.
If the data is being computed on the fly, then write your data to a
ByteArrayOutputStream first, then use byte data[] =
ByteArrayOutputStream.toByteArray() to get something to send to the
response.
Here's an example of what might happen if you don't.

1. What are the consequences if I get the length wrong? Does it have

2. Can the setContentLength() be called after I have done all the

beforehand, then I can compute the length as I go. Otherwise, it will
be more difficult.

And it's even easier if one is generating a text file (rather than a
binary file), for example, when writing out a comma-separated file for
use in a spreadsheet, since one can use
response.getWriter().print(String s) and
response.getWriter().println(String s).

It is actualy much easier in JSF. You just need to have an action
method
in
a (managed) bean, like this:
public String downloadFile() {
FacesContext facesContext = FacesContext.getCurrentInstance();
if (!facesContext.getResponseComplete()) {
String fileName = myfile.pdf;
ServletContext servletContext = (ServletContext)
facesContext.getExternalContext().getContext();
String contentType =
servletContext.getMimeType(fileName);
HttpServletResponse response = (HttpServletResponse)
facesContext.getExternalContext().getResponse();
response.setContentType(contentType);
response.setHeader(Content-Disposition,
attachment;filename=\ + fileName + \);
try {
InputStream in = /* get your data */;
ServletOutputStream out =
response.getOutputStream();
byte[] buf = new byte[512];
int bytesRead;
while ((bytesRead = in.read(buf, 0, bufSize))
!=
-1)
{
out.write(buf, 0, bytesRead);
}
out.flush();
facesContext.responseComplete();
} catch (IOException e) {
throw new RuntimeException(e);
}
}
return null;
}
Then you can simply call the method from a commandLink or
commandButton
h:commandLink action=#{yourBean.downloadFile}
h:outputText value=download /
/h:commandLink

Re: Comparable validation design
I've put an initial version of this validator at the following URL (manually constructed since the link isn't active yet -- may have typos). http://cvs.sourceforge.net/viewcvs.py/jsf-comp/componentsandbox/src/java/org/apache/myfaces/custom/comparetovalidator/CompareToValidator.java It'll probably take a little time for the link to become active, so you might have better luck grabbing it from jsf-comp cvs directly. Make sure to get at least Revision: 1.2 as I added the documentation in that revision. I can also email it to anyone who wants it.

Re: curious problem with dates
Yes, it's the same problem as the thread from a few days back with
headache in the subject (which is a very fitting subject I might add).
I have to deal with this same problem so I think I'll probably just end
up making a component that extends the normal DateTimeConverter and
acts like would be expected. Maybe a sandbox candidate if others
are interested?

User defined message for component
Hello I would like to use my own error message
I use h:message for=nickname
h:inputText id=nickname value=#{Register.nickname} required=true
size=10
maxlength=24/
h:message for=nickname/
This generates the error message nickname: Value is required. I would like
to replace this with my own message.
My recipe:
1) In faces-config.xml config file I have the entry
faces-config
application
message-bundleorg.partneragency.web.validatormessage/message-bundle
/application
...
/faces-config
2) In validatormessage.properties I add the entry
nickname=nickname must be set
This does not work.
Re: User defined message for component
This is guesswork, but I came across message keys in the JSF 1.2 spec
earlier today.
I think you might be able to use this entry instead:
javax.faces.component.UIInput.REQUIRED={0} must be set
The original value was
javax.faces.component.UIInput.REQUIRED={0}: Validation Error: Value is required
Unfortunately, the ability to specify required message keys at the tag
level (requiredMessage=.) isn't available until JSF 1.2.
Also note that you can define
h:outputLabel for=nickname
h:outputText value=nickname/
/h:outputLabel
and whatever the value of the outputLabel is will be used for {0} in
your message key. This is probably more useful when the id can't
contain the display value (ie, Last Name instead of lastname).

DataTable Problem
We're experiencing a problem using a commandLink (or commandButton)
inside a dataTable. We're hoping that it's just something we're doing
wrong.
If we copy the commandLink outside the dataTable (just as a test), and
then click on the commandLink outside the dataTable, then control goes
to the desired page.
However, if we click on the commandLink that is inside the table, the
same page gets displayed (with an empty table).
Here is the JSP code:
t:commandLink action=displayHome title=Skill Id
styleClass=commandLinkHomePage
h:outputText value=test styleClass=link/
/t:commandLink
t:dataTable value=#{maintainSkillBean.skillList} var=element
headerClass=reportHeader columnClasses=reportDetailLeft
cellpadding=2 cellspacing=2
t:column
f:facet name=header
h:outputText value=Skill Id/
/f:facet
t:commandLink action=displayHome title=Skill Id
styleClass=commandLinkHomePage
h:outputText value=#{element.skillId}
styleClass=link/
/t:commandLink
/t:column
/t:dataTable
Any clues about why clicking the first commandLink would correctly bring
us to the home page, whereas clicking the second commandLink would just
redisplay the current page? We have t:messages up top, and no error
messages are getting displayed.
- Brendan
P.S. We tried this with both 1.1.1RC2 and 1.1.1RC3, and we're getting
the same result. We also tried using both t:dataTable and
h:dataTable, but still no luck.

Hi,
I am new to jsf and just beginning to put together some
pages. I am playing with a form that has an event listener on a selection list,
the form refreshes depending on the selection. I discovered that if I click too
fast jsf will throw the following exception:
01:07:42,794 ERROR [FacesServlet]:253 -
Servlet.service() for servlet FacesServlet threw exception
javax.faces.el.EvaluationException: Cannot get value for _expression_ '#{userBean.userIdsList}'
What is the best way to handle this situation?
Many thanks in advance.
