In reference to this question,
it still accepts 8/1/201987 as a date, where in 201987 is not in yyyy format.
How to ensure yyyy format? Do I need to validate it in the bean?
I have used the code below :
<p:calendar ...>
<f:convertDateTime pattern="dd/MM/yyyy" />
</p:calendar>
But as it uses SimpleDateFormat, if you give yyyy it accepts any number of digits.
How to resolve this issue?
Try mask for p:calender like mask="99/99/9999", it's works fine for me
<p:calendar value="8/1/201989" mask="99/99/9999">
<f:convertDateTime pattern="dd/MM/yyyy" />
</p:calendar>
You can restrict the user input by adding attributes mask="true" and maxlength=10

I got a <p:calendar> and want to use today's date as placeholder.
My attempt is to use OmniFaces #{now} in combination with a:placeholder for this:
<p:calendar id="calendar" a:placeholder="#{now}" minHour="8" locale="de"
maxHour="20" value="#{adminSeminarAlleBearbeitung.seminar.someproperty}"
pattern="dd.MM.yyyy HH:mm" />
Where someproperty is a java.util.date.
This is working so far, but I want to format the date like dd.MM.yyyy HH:mm.
How can I achieve this?
Use of:formatDate() function in EL:
<p:calendar ... a:placeholder="#{of:formatDate(now, 'dd.MM.yyyy HH:mm')}" />
Or if you'd like to reuse calendar component's own pattern attribute:
<p:calendar ... a:placeholder="#{of:formatDate(now, component.pattern)}" pattern="dd.MM.yyyy HH:mm" />

I have a <p:calendar> code in XHTML
<p:calendar
value="#{Bean.targetdate}"
pattern="MM/dd/yyyy" size="10" navigator="true"
rendered="#{Bean.editCmdActionflg == true}"
onblur="fChkDate(this);">
<f:convertDateTime type="date" pattern="MM/dd/yyyy" />
My problem is when I provide a invalid date such as 12/31/6666 the <p:calendar> accept the date as it is and I did SOP in the backing bean and I got Mon Dec 31 00:00:00 IST 6666 for the date that I enter.
I should not allow the user to enter a invalid date like the one that I entered above.
And I need to make sure the user should provide a valid date How can I do that ?
You can use yearRange property to reslve your problem, like-
<p:calendar yearRange="c-125:c+50" value="#{Bean.targetdate}" pattern="MM/dd/yyyy" readonlyInput="true" size="10" navigator="true"
rendered="#{Bean.editCmdActionflg == true}"
onblur="fChkDate(this);"/>
my calendar has readOnlyInput="false" , hence the user can enter wrong dates such as 13/13/2013.
is there a way to regexValidate my date in case the user prefers to type the date instead of using the datePicker popup ?
<p:calendar id="birthDate" size="22" locale="#{view.locale}"
maxdate="#{userCreationBean.maxDate}" navigator="true"
yearRange="c-100" readOnlyInput="false"
value="#{userCreationBean.user.birthDate}"
mindate="01/01/1900" pattern="dd/MM/yyyy"
style="left: 194px !important;"

</p:calendar>
The <f:validateRegex> validator works on String input values only, not on Date input values and is therefore insuitable for the purpose you had in mind.
Rather use the <f:convertDateTime> converter.
<p:calendar ...>
<f:convertDateTime pattern="dd/MM/yyyy" />
</p:calendar>
It's by default non-lenient and will thus throw a converter exception when an invalid date is entered. You can if necessary customize the converter message by converterMessage attribute on the input component.
I wonder how to validate an inputText text field and see if it matchs a decimal format.
And also in the rendering time how to format that text field with a specific format
I've done this :
<rich:column id="soldes_comptables">
<f:facet name="header">
<h:outputText value="Solde Comptable" />
</f:facet>
<h:inputText id="inputTextSC" value="#{file.soldes_comptables}"
label="Montant"
style="border-color:#F2F3F7;"
validatorMessage="The number must be decimal eg: 000.00"
>
<f:convertNumber pattern="#,###,##0.00"/>
<f:validateRegex pattern="^[0-9]+(\.[0-9]{1,2})?$"></f:validateRegex>
<rich:validator />
</h:inputText>
<rich:message for="inputTextSC"/>
</rich:column>
but it's not working as i want :(. please help me
You're mixing validation and conversion. The <f:validateRegex> applies only on String values, not on Number values, however, the <f:convertNumber> has already converted it from String to Number beforehand, so the <f:validateRegex> is rather useless to you. You should remove it and specify the message as converterMessage instead.
<h:inputText ... converterMessage="The number must be decimal eg: 000.00">
<f:convertNumber pattern="#,###,##0.00"/>
</h:inputText>
An alternative would be to create a custom converter extending NumberConverter and throw a ConverterException on improper input format based on some regex pattern matching.

How validate number fields with validateRegex in a JSF-Page?
We have an object with java.util.Calendar objects. We would like to display the data on a JSF page (preferably in the same format we have for java.util.Date objects). It seems like there should be some clean way to do this other than creating a wrapper class just to convert the Calendar to a Date.
What is the cleanest way to display the date/time held in a java.util.Calendar in a JSF page?
Use Calendar's own getter Calendar#getTime(). It returns a Date. Then you can use <f:convertDateTime> the usual way.
<h:outputText value="#{bean.calendar.time}">
<f:convertDateTime type="both" dateStyle="long" />
</h:outputText>
For others and #seangates: You CAN apply a pattern if using the Calendar object. E.g.
<h:outputText value="#{bean.calendar.time}" styleClass="date">
<f:convertDateTime pattern="EEEE, MMMM d yyyy" />
</h:outputText>
<h:outputText value="#{bean.calendar.time}" styleClass="time">
<f:convertDateTime pattern="hh:mm" />
</h:outputText>
If you need futher Text:
<h:outputFormat
value="#This my date: {0,date,long}">
<f:param value="#{bean.calendar.time}" />
</h:outputFormat>
