updateActionListener within tree2
I'm new to MyFaces and having some problems using updateActionListener inside a
tree2, I get Action listener for property is not present when clicking the
commandButton.
MyFaces 1.1.3 + Tomahawk 1.1.3 + Facelets + updateActionListener tag handler
from Wiki
2006-07-11 10:04:28,379 DEBUG http-8180-Processor20

com.myapp.util.TomahawkUpdateActionListenerHandler - Action listener for
property is not present. Property: #{patientEvent.currentEvent}
The same updateActionListener works fine within a t:dataTable.
I've looked around and can't find any mention of this specific problem, does
any know of any issues?
I'd appreciate some pointers.
Thanks

selectManyListbox custom converter toString() problem
I'm having some trouble using a selectManyListbox with a custom
converter.
My select items are composed of an object value and string label as
follows:
LookupItem item = ... // simple lookup - integer values and a
description label.
String label = item.getLabel(locale);
SelectItem selectItem = new SelectItem(item,label);
...
CollectionSelectItem lookupItems = new ArrayListSelectItem();
...
Selected values in the backing bean are held in an ArrayList.
t:selectManyListbox
value=#{mybean.selectedItems}
size=30
f:selectItems value=#{mybean.lookupItems } /
f:converter
converterId=com.mydomain.MyConverter /
/t:selectManyListbox
I've written a custom converter which works fine if I use it with a
SelectOne.. type component but when I try it with a SelectMany..
getAsString() is passed a String value containing the selected value
instead of a LookupItem object.
public String getAsString(FacesContext facesContext, UIComponent
component, Object value)
throws ConverterException {
if (value != null) {
return ((LookupItem) value).getCode().toString();
}
return null;
}
java.lang.ClassCastException: java.lang.String
at com.mydomain.MyConverter.getAsString(Unknown Source)
Maybe I'm missing something but I expected getAsString() to be passed
the converted LookupItem object.
I'd appreciate some help.

Date output and timezone
I would appreciate some suggestions for the handing of dates:
I'm using Tomahawk t:inputDate .../ to collect a person's date of birth in a
backing bean variable of type Date.
When I subsequently view the date using a simple h:outputText ../ it displays
the original date minus 1 day, even though the Date variable is set correctly.
For example I enter 01-Jan-1965 and outputText displays 31-Dec-1964.
I'm not using any converters and I assume that the default converter is taking
in to account my timezone, I'm on CET (GMT+1), and calculating 01-Jan-1965
00:00:00 minus 1 hour to display the GMT time (correct?).
The application is going to be accessed from different timezones but the date
display must be exactly as entered.
What would be the easiest/cleanest way to get around this problem?
I guess I could dynamically set f:convertDateTime
timeZone=#{User.timeZone}/ to the user's timezone but I'd rather the date
was simply treated as a Date without any time and timezone.

dataTable master/detail getRowData() - help needed
I'm trying to implement a master-detail type scenario where a search
is performed to populate a dataTable with a list of users, the user
name can then be clicked to view the details.
The method I am attempting to use is described on the Myfaces Wiki -
3) Getting handle to DataModel Row
http://wiki.apache.org/myfaces/ExecutingMethodsFromLinkButtonParameters
When I have my managed bean set to session scope it all works fine,
the only problem is that I don't want it in the session scope, once
set to request scope the userDetails method does not get fired when I
click on the commandLink, I simply get bumped back to the original
view with a blank data table.
I have tried using t:saveState/ but I get an error as
org.apache.myfaces.component.html.ext.HtmlDataTable is not serializable.
Relevant code:
managed-bean
managed-bean-nameuserAdmin/managed-bean-name
managed-bean-classcom.mydomain.view.bean.UserAdminBean/
managed-bean-class
managed-bean-scoperequest/managed-bean-scope

users.xhtml
..
t:dataTable
value=#{userAdmin.foundUsers} var=user
binding=#{userAdmin.userTable}
rendered=#{userAdmin.displayResults}
preserveDataModel=true
h:column id=col1
f:facet name=header
h:outputText value=#{msgs['label.user.id']} /
/f:facet
t:commandLink action=#{userAdmin.userDetails}
value=#{user.userId} /
/h:column
/t:dataTable
UserAdminBean.java
...
private UIData userTable;
...
public String userDetails()
User appUser = (User) userTable.getRowData();
getApplication().createValueBinding(#{appUser}).setValue
(getFacesContext(), appUser);
return Constants.SUCCESS;
}
One thing particularly puzzling me is why the userDetails() method
does not get fired at all when clicking the commandLink.
Being new to JSF it's probably my lack of understanding of the
lifecycle but I'd appreciate some pointers as to how other people
have solved this problem without resorting to placing the dataTable
in the session scope.

inputDate JavaScript generation problem
Hi I've got a newbie question regarding components and JavaScript generation. I'm using t:inputDate with popupCalendar=true but when I click the button to display the popup calendar nothing happens, this is because the necessary JavaScript link tags are not present in the page. When I run the MyFaces examples for the date input component it works perfectly and the links to the JavaScript and CSS are in the page header. As far as I can tell from the example these links should be auto- generated by the component or maybe I'm missing something obvious? Suggestions appreciated. Thanks Gianni PS. I've got org.apache.myfaces.ALLOW_JAVASCRIPT set to 'true'

Re: TR : Dynamic Locale change
I suggest you take a look at the list archives for Maintain locale
across views.
I had a similar issue and it seems the locale is not maintained
across views when a redirect/ is used.
In the end I set f:view locale=#{visit.locale}, where visit is a
session scoped bean.
Gianni
Sorry for asking so much questions but I'll have to present my
webapp very soon and I need the multi-language to works fine.
Has anybody any idea ? Why the locale is reset to the default
one ? Could it comes from a redirect/ instruction in my faces-
config.xml ?
Ty for your help :D

*Objet :* Dynamic Locale change
Hi,
I'm trying to allow the application user to change the language of
my web app.
I did it the way it is done in the myFaces 1.0.9 examples : a
selectOneMenu with a choice of languages and an action button with
that code :
OptionBean {
...
public String action {
...
FacesUtil.setLocale(selectedLocale);
...
}
...
}
FacesUtil {
...
public static void setLocale(Locale l) {
FacesContext.getCurrentInstance().getFacesContext().getViewRoot
().setLocale(l);
}
...
}
It works fine when the action is executed (the language change),
but as soon as I navigate to another page of the App, the language
is resetted to the default one. Why ?
NB : I'm trying not to use the /locale/ parameter of the /
f:view/ tag ...
Thx,
Clément.
Maintain locale across views
I'm starting out with JSF and I'd appreciate some clarification regarding internationalization: I'm using a select menu and backing bean to call setLocale() on the current view, this works fine and I can change the locale of the view in question. But when I navigate to another view the locale reverts back to the browser default. Is this correct behavior? Do I need to set the locale myself on a per-view basis or should JSF maintain the locale between views? If this is the case then I guess I need to store the view's local in the session and use this to set the locale for subsequent views. Where and how would be the best way to do this in terms of the JSF lifecycle? I also have tiles in the mix using MyFaces JspTilesViewHandlerImpl, does this have any implications for how I need to handle internationalization? Thanks Gianni
Re: Maintain locale across views
I tried with the RI and was still getting the same issue then I realised it may be something to do with the fact I was using redirect/ in the navigation rule. If I take out the redirect/ then the locale is maintained across views, with redirect it's not.

Actually, that is *not* correct, for requests after the initial one (where the browser's accept-language header is used to set the default if the app doesn't do it). Details are in the JSF spec, section 2.2.1, but the basic idea is that, if you are already in a flow of views managed by JSF, *and* if a locale has been established, it should also be carried forward to any created view -- the app should not have to do this manually on every view. The RI does it this way, by the way. Craig
Re: Tiles subview mixing html and jsf
Thanks for the responses. I got around it in the end by using this library: http://jsftutorials.net/htmLib/ I would have liked to use plain html mixed with the jsf but it seems that there is simply no practical way to do this in a subview using the jsp xml syntax. Gianni On 06/lug/05, at 21:49, Martin Marinschek wrote: Yes, that is the reason... of course, in XML the syntax needs to be followed correctly, and you cannot have opening tags without an according closing tag. Sylvain proposed to have an html tag which would render out the provided html code out - is this already included? If yes, you could use this approach...
