title: Set start date in Calendar RichFaces
body: <p>I need to set a start date in a calendar component richfaces. I have a variable called <code>dateInitial</code> in my ManagedBean that have a Date (i.e 2013-07-07 are lower limit date) and I configure my calendar component :</p>
  
  <pre><code> &lt;rich:calendar id="dateToEvaluate" popup="true" 
      required="true" requiredMessage="Required Field"
      buttonIcon="#{request.contextPath}/resources/images/calendar.gif"
      value="#{valueMB.dateToEvaluate}"
      datePattern="dd/MM/yyyy"&gt;
   &lt;/rich:calendar&gt;
  </code></pre>
  
  <p>But I need <strong>validate</strong> that the value of that are greater than my variable <code>dateInitial</code>, if not .. then launch a message validator with the error. </p>
  
  <p>Thanks for advance! and I'm sorry for my bad english. </p>
