Primefaces calendar component manually entering date beyond maxdate validation fails - validation

Question

I'm trying to add a Calendar input component in an application.
The Calendar input component to pick a datetime and the max date restriction works ie doesn't allow to select future date
Greys out the future date - works fine / User cannot select a future date
Problem is the user can enter the future date manually, it is not validating this field.
User is able to enter the future date manually
5/24/2021
6/2/2020
<p:calendar id="userdate" value="#{calendarView.pricedate}" maxdate="#{calendarView.maxDate}" />
calendarView.java
private Date maxDate = new Date();
public Date getMaxDate() {
return maxDate;
}
public void setMaxDate(Date maxDate) {
this.maxDate = new Date();
}
Primefaces Version
<primefaces.version>6.2</primefaces.version>
How to validate this component when user enters the field value manually, I have added a max date validation attribute.

A simple search in a search engine of your liking
One that tracks you
Or even one that does not track you
Would have shown
Calendar: does not validate the input against mindate/maxdate
With a fix version of 7.0
And to prove it I created a real full [mcve]:
XHMTL:
<h:form>
<p:messages id="messages"/>
<p:calendar id="registrationDate" value="#{testView3582.date}" mindate="#{testView3582.minDate}" maxdate="#{testView3582.maxDate}" navigator="true" yearRange="c-2:c" showButtonPanel="true"
mask="true" styleClass="#{testView3582.maxDate}"/>
<p:commandButton value="submit" update="messages" />
</h:form>
Bean:
#Named(value = "testView3582")
#ViewScoped
public class TestView implements Serializable {
Date date;
Date minDate;
Date maxDate;
#PostConstruct
public void init() {
Calendar cal = Calendar.getInstance();
date = cal.getTime();
cal.add(Calendar.DAY_OF_YEAR, -10);
minDate = cal.getTime();
cal.add(Calendar.DAY_OF_YEAR, +20);
maxDate = cal.getTime();
}
//Getters/Setters omitted
}
With a min/max date of 10 days before now and 10 days past and when manually entering 04/20/20 and pressing submit I get

Always search the issue list (contains a workaround for previous versions, see also the other answer)
Always create a real minimal reproducible example
Always try with a newer version (preferably latest)
