Show value in validatorMessage - primefaces

Question

I am using a validatorMessage for a regex I have for an email input, but I want to show the current value from the input in the message, at the place {0}.
But if I used the variable that is declared in the bean it doesn't work, because it doesn't process the variables because there is an validation error. How would I show the current value in the input in the validatorMessage?
Note: {0} is used in the PrimeFaces locales for the current value with validating.
<p:inputText id="email" value="#{registerBean.email}" type="email" label="#{bundle.register_email}" required="true" style="width: 100%;" validatorMessage="#{bundle.register_email}: '{0}' #{bundle.register_email_error}">
<f:validateRegex pattern="^[_A-Za-z0-9-\+]+(\.[_A-Za-z0-9-]+)*#[A-Za-z0-9-]+(\.[A-Za-z0-9]+)*(\.[A-Za-z]{2,})$" />
</p:inputText>

Answer 1

The solution I propose is to use a custom "messages.properties" file and overwrite the default messages of JSF API.
For an example of this file please redirect to: jsf-api-2.x.jar, "javax \ faces \ Messages.properties".
Take for example the two values found in the file messages.properties
javax.faces.validator.LengthValidator.MAXIMUM={1}: Validation Error: Length is greater than allowable maximum of ''{0}''
javax.faces.validator.LengthValidator.MINIMUM={1}: Validation Error: Length is less than allowable minimum of ''{0}'
For example,
If maximum length validation failed, JSF gets “javax.faces.validator.LengthValidator.MAXIMUM”.
If minimum length validation failed, JSF gets “javax.faces.validator.LengthValidator.MINIMUM”.
Personalized Message
Create a file (with any name) for exemple: myMessages.properties and place them in a specific package in your source folder.
Place in all the messages you find in the file of the messages.properties jsf-api-api 2.x.jar .
Then change the message as you like, for example:
javax.faces.validator.LengthValidator.MAXIMUM=My custom message 1
javax.faces.validator.LengthValidator.MINIMUM=My custom message 2
Register Message Bundle
Register your custom properties file in “faces-config.xml”, put it as Application level.
faces-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<faces-config
xmlns="http://java.sun.com/xml/ns/javaee"
