p:joinClasses
Purpose
Joins a list of CSS classes, safely handling null values and ensuring no extra whitespace is produced.Example
<div class="${g.joinClasses(values:[userClass, 'notice', 'alert'])}">
..
</div>
This would output the class attribute as class="somevalue notice alert" if userClass was set to "somevalue".Attributes
