title: What is label's 'for' id for selectBooleanCheckbox
body: <p>How to reference each individual checkbox in the outputLabel so that when I click on item's label, it would effectively be the same as if I clicked on the checkbox?</p>
  
  <pre><code>&lt;rich:dataGrid value="#{all}" var="item" columns="3"&gt;
      &lt;h:outputLabel value="#{item.name}" for="what_here?" /&gt;
      &lt;h:selectBooleanCheckbox value="#{item.selectedForLaterUse}" id="item#{item.id}" /&gt;
  &lt;/rich:dataGrid&gt;
  </code></pre>
  
  <p>A possibility that comes first to mind is of course</p>
  
  <pre><code>  for="item#{item.id}"
  </code></pre>
  
  <p>but since jsf id's are relative, it would not work, right?</p>
  
  <p>There is also one option to use selectManyCheckbox but that doesn't seem to give an option to use columns.</p>
