title: How I hide empty Velocity variable names?
body: <p>I am using Struts + Velocity in a Java application, but after I submit a form, the confirmation page (Velocity template) shows the variable names instead an empty label, like the Age in following example:</p>
  <blockquote>
  <p><strong>Name</strong>: Fernando</p>
  <p><strong>Age</strong>: {person.age}</p>
  <p><strong>Sex</strong>: Male</p>
  </blockquote>
  <p>I would like to know how to hide it!</p>
