how to do autocomplete=”off” at form level in JSF

by

The best and easiest way of doing this is this:

<h:form id="myForm">
    <f:passThroughAttribute name="autocomplete" value="off"/>
    ...
</h:form>

Don’t forget to add xmlns:f="http://xmlns.jcp.org/jsf/core" to your head attribite if you don’t have already.

Why?

  1. Because if you have an ajax event somewhere in your page that needs to update/render your form, it will not loose the autocomplete attribute.
  2. Because it looks sexy (JS way looks ugly).

Tip: You can use f:passThroughAttribute for every JSF element which does not have any specific attribute of newer HTML specifications.
