t:inputDate value problem in tomahawk 1.1.9
Hi,
I just tested the following code:
t:inputDate id=bDate type=date value=#{user.bDate}
popupCalendar=true/
I am using Myfaces-1.2.8, facelets-1.1.15, and tomahawk-1.1.9. Everything
looks fine, but the value of the input date comes out to be a day earlier.
For example, if I choose 15 January 2010 in the calendar, it assigns 14
January 2010 to user.bDate. Same thing happens if I disable
popupCalendar, and type the date.
Is this the bug, incompatibility issue, or I am missing something.
Any pointers would be highly appreciated.

t:selectOneMenu f:selectItems problem
Hi,
I am trying to create a selctOneMenum, and I have the following snapshot of
xhmtl file:
t:selectOneMenu value=#{libraryUser.group}

Choice.java (choice.groups) is as follows:
public class Choice {

public Choice() {
groups.add(new SelectItem(1,Test));
groups.add(new SelectItem(2,Test1));
}
public ListSelectItem getGroups() {
return groups;
}
public void setGroups(ListSelectItem groups) {
this.groups = groups;
}
}
I, however, is getting error message:

Hi Damar,
It seems like somehow #{choice.groups} resolves to null.
I don't really know why, but you can try to debug your app and look at the
value of groups. Either some part of your code sets groups to null or it is
not initialised at all.
In your case, I would write Choice.java in the following way:
public class Choice {
private ListSelectItem groups;
public Choice() {
}
public ListSelectItem getGroups() {
if (groups == null)
{
groups = new ArrayListSelectItem();
groups.add(new SelectItem(1,Test));
groups.add(new SelectItem(2,Test1));
}
return groups;
}
public void setGroups(ListSelectItem groups) {
this.groups = groups;

Re: c:if question
Hi,
Thanks for your message.
I am seeing a weird situation!
The following snapshot works fine (can display the required output
correctly!):
h:selectOneMenu id=htmlOrText value=#{email.htmlOrText}
f:selectItem itemValue=text itemLabel=Text/
f:selectItem itemValue=html itemLabel=Html/
a4j:support event=onchange
reRender=txt,isTxt,isHtml ajaxSingle=true/
/h:selectOneMenu
h:outputText id=txtHtml value=#{email.htmlOrText}/
Text:
h:outputText id=isTxt value=#{email.htmlOrText ==
'text'}/
Html:
h:outputText id=isHtml value=#{email.htmlOrText ==
'html'}/
But, when I try the following (ironically, the real code that I need!), it
does not render:
h:selectOneMenu id=htmlOrText value=#{email.htmlOrText}
f:selectItem itemValue=text itemLabel=Text/
f:selectItem itemValue=html itemLabel=Html/
a4j:support event=onchange reRender=txt, htm
ajaxSingle=true/
/h:selectOneMenu
h:inputTextarea id=txt value=#{email.bodyEmail}
cols=70 rows=15 rendered=#{email.htmlOrText == 'text'} /
t:inputHtml id=htm value=#{email.bodyEmail}
addKupuLogo=false rendered=#{email.htmlOrText == 'text'} /
Any pointers on this?
Thanks once again.

Re: Selectable DataTable or similar to that
Hi,
Thank you, every body, for your great help.
But, I have the following snapshot of my Action method:
java.util.ArrayList data=this.applications;
Iterator FirstObject it=data.iterator();
String title=;
java.util.ArrayListStudents students=new java.util.ArrayList();
while(it.hasNext ()) {
FirstObject first=(FirstObject) it.next();
title=first.getCourseTitle();
Student student=selectable.getStudent();
Students.add(student);
…….
…
}
SecondObject second=new SecondObject(title,students…)
In the above, this.application is the list of FirstObjects that comes
from the dataTable. Up to this point I am getting right list.
In the second part, I iterate the list, and get title and students list.
In the third part, I create second of SecondObject class, using the
value of title, students from second part.
I am getting the following error:

Your logic is off; you get the parent but aren't testing it's class before

Hi,
speaking in code, it would be something like this:
public void deleteRow(ActionEvent actionEvent)
{
UIData uiData = JsfUtils.getUIDataParent(actionEvent);
getList().remove(uiData.getRowIndex());
}
In JsfUtils:
public static UIData getUIDataParent(ActionEvent e)
{
UIComponent component = e.getComponent();
while (component != null !(component instanceof UIData))
{
component = component.getParent();
}
return (UIData) component;

Hi Damar,
I think one way to do this is write a simple class:
public class SelectableApplicant {
private boolean isSelected;
private Applicant applicant;
// add getters/setters for above
}
Change applicationProcess.applicants to return a list of
SelectableApplicant rather than Applicant directly.
Your JSP columns can be:
h:column
t:selectBooleanCheckbox .. value=#{application.selected}/
/h:column
h:column
h:outputText value=#{application.applicant.firstName}/
/h:column
etc.
Obviously, you can now iterate over the rows in the data model, checking
the boolean flag and if set processing the associated applicant object.

In the above, changeApplicationList (value change method) changes the
list of applications list that is used by dataTable to display
applications. The following is the snapshot of my
changeApplicationList method (ValueChangeEvent):
String course=(String) event.getNewValue();
java.util.ArrayList list=new java.util.ArrayList();
while (result.hasNext()){
fill list with application….
}
}
this.setApplications(list);
}
}
My question is what triggers to render/re-render dataTable when value
is change in SelectOnMenu? Mine is not working.
Thanks,

Well yeah, though he probably wants check boxes, to be able to select
several at once. In that case, you can have a dataTable column like:

Hi,
well, there should be a more nicer solution in order to achieve

Have a look at the sandbox-examples page. An addition to
t:dataTable
does exist to get one row selected:

Should be exactly what you need?

Help in writing Validator
Hi, I have one h:inputText field that I would like to validate against the availability of that entry in the database -- accept only if the input text is in the database. Can somebody in list list give me some pointers on this? Thanks, With regards, Damar Thapa

Hi Cagatay,
Thanks for your pointers. I will look at the options.

Hi,
There are several choices, you may try to write a validator method in your
managed bean and do a method binding to it via the validator attribute like;
h:inputText validator=#{beanname.validatormethod } /
public void validateCode(FacesContext facesContext, UIComponent component,
Object value) {
//throw new ValidationException if you think value is not valid
}
Also for better reusing, you can write your own validator and bind it to the
inputText by the f:validator /
http://publib.boulder.ibm.com/infocenter/radhelp/v6r0m1/index.jsp?topic=/com.ibm.etools.jsf.doc/topics/tjsfcrvalidator.html
In addition you can create it's own tag for your validator like in;

General JSF question -- Class object!
Hi,
I have following classes:
Class Course(
String title,
String startDate.
…..
….
}
and
Class Apply{
String studnetName;
Course firstChoice;
.
…….
…..
}
In the apply form (page), I havae a field to accept course title from
the applicant ie h:inputText id=firstChoice
value=#{applicant.firstChoice.title}/. Since title is unique, I can
retrieve Course object for firstChoice properties later before saving
Apply object. But, I am getting firstChoice: Error during model
data update. error on #{applicant.firstChoice.title} . Can somebody
on the list point me what am I missing?
Any pointers would be highly appreciated.
Thanks,
Damar
Re: General JSF question -- Class object!
Hi David,
Thanks for your prompt reply.
I am trying similar to your first suggestion. In your case, I
suppose, firstChoice has to be type String, but I made firstChoice as
type Course, where Course has several properties and one of them is
title. So I am trying to do similary to:
h:selectOne id=firstChoice value =#{applicant.firstChoice.title}
f:selectItems value=#{school.availableCourses}/
/h:selectOne
Basically, trying to bind value to #{applicant.firstChoice.title}
instead. Is it possible?
Thanks,
Damar

Hi,
Am a little confused by your explaination. I bet you are transforming a

I have 2 suggestions:
The first it to replace you textfield with a combo box, like this
h:selectOne id=firstChoice value =#{applicant.firstChoice}
f:selectItems value=#{school.availableCourses}/
/h:selectOne
with your school bean having something like this
public SelectItems[] getAvailableCourses(){
...
}
The second way to go is to use a converter
h:inputText id=firstChoice value =#{applicant.firstChoice}
f:converter converterId=my.custom.Converter/
/h:inputText
with the converter define in you faces-config.xml:
converter
converter-idmy.custom.Converter/converter-id
converter-classpath.to.my.custom.CourseConverter/converter-class

This all depends on what you want to do
Do you want to 'set the title of firstChoice'? then you map to
#{applicant.firstChoice.title}

The SelectItem[] is use to select amongst a list of possible values. You
don't have to care how they are wired at html level, You just provide a
list of SelectItem[] object which have a visual label (type String), a
description (type String, never used) and a Value (type Object). So you
can put in value whatever you want, JSF will take care that when an item
is selected for selectbox, the backing bean will be update with
something like setFirstChoice(selectedItem.getValue()).
Btw, sorry, this is not h:selectOne but h:selectOneMenu :D

Re: General JSF question -- Class object!
Hi Rene,
Possibly, it is null. I am still getting firstChoice: Error during
model data update. error. I can add two more attribues of type
String to hold firstChoice and secondChoice in Applicant class, but as
a matter of interest and learning, how it works in JSF?
Thanks,
