How to call a method with a parameter in JSF

by

Passing method arguments was introduced in EL 2.2. So this is only possible if you’re running on a Servlet 3.0 / EL 2.2 capable container like Tomcat 7, Glassfish 3, JBoss AS 6, etc and your web.xml is been declared as per Servlet 3.0 specification.

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
>
    <!-- Config here -->
</web-app>

If you aren’t, then check this answer for alternatives with regard to obtaining current row in datatables, or this answer with regard to replacing the EL implementation by one which supports passing method arguments so that you can use it on Servlet 2.5 / EL 2.1 containers as well.
