Ajax update and submission using h:commandButton

by

This is to be done by nesting a <f:ajax> in it.

In effects,

<p:commandButton ... process="@form" update=":statusBlock" />

does exactly the same as

<h:commandButton ...>
    <f:ajax execute="@form" render=":statusBlock" />
</h:commandButton>

Note that the subtle difference with the PrimeFaces equivalent is that PrimeFaces defaults to @form in the process/execute, while the <f:ajax> one defaults to @this, so you might need to explicitly specify execute="@form" over all place where you didn’t specify the process attribute in the PrimeFaces component.
