about how to use validator
Hi, as a friendly reminder, I took some notes on the usage of validator which is important for the exam.
The validator attribute and f:validator always confuse people.

As we know we have <h:inputText ... validator="{any method expression}"/>, or <f:validator validatorId="any validator id"} , there is still another usage like this:
<h:inputText...>
   <f:validator binding="#{name of a validator which is a managed bean}
</h:inputText>
For example,


The jsf to use it is :
<h:inputText ...>
         <f:validator binding="#{EmailValidator1}"/>
</h:inputText>

Reference:https://bitbucket.org/paulstat/oracle-jsf-expert-1z0-896/wiki/Custom%20validators
In the above reference, Paul uses CDI bean for the validator. But it does not work with my Glassfish. It may work with other containers.
