body: <p>I'm using <strong>PrimeFaces v.5</strong> with this version a new component is released that <a href="http://www.primefaces.org/showcase/ui/data/datatable/columnToggler.xhtml" rel="noreferrer">ColumnToggler</a>, when view is rendered, refreshed all checkbox are checked as a default operation.</p>
