title: How to make JSF inputText field upper case on blur
body: <p>I would like to make a JSF inputText field into upper case when the user moves focus away from the field. Would it be best to do this using the <code>f:ajax</code> tag and have the <code>blur</code> event trigger a call to the server to do the uppercasing, or would it be best to do this in JavaScript? What would the reason be <em>not</em> to do this in JavaScript? Is it best to always do these sorts of things using an ajax call to the server side?</p>
