title: Call existing trigger on Opportunity Update
body: <p>Probably an easy answer I cannot find. I'm trying to call an existing trigger when the Opportunity Stage is set to 'Closed Won'. Not sure how to execute it. The existing trigger executes a Visualforce component.</p>
  
  <pre><code>trigger create_cc_project on Opportunity (after insert,after update)
   {
      if(Opportunity.stagename=='Closed Won')
   then(cc.ccUtility.asyncInitiateProject('Opportunity', Opportunity.Id));
      }
  </code></pre>
