title: Why process="@this" needed for primefaces command button
body: <p>Some of the command buttons' <code>actionListener</code> event of the xhtml page of my JSF app did not work until I added attribute <code>process="@this"</code> to the <code>&lt;p:commandButton..</code> tag. I am wondering why. I haven't seen this in any example. I am using a combination of JSF 2.2 &amp; CDI, along with Primefaces 5.0 on JBoss 7.1 runtime. My beans are CDI <code>@javax.inject.Named</code> beans and scope is <code>@javax.enterprise.context.RequestScoped</code>..</p>
