title: Dynamic property key
body: <p>My project has several events and I store event IDs in Site Properties and as each event page extends the same core template I want to assign the specific event ID to a generic variable. </p>
  
  <p>The issue is that when I try to insert a variable inside the property key reference freemarker returns syntax errors. Is there any way around this?</p>
  
  <pre><code>${sectionName}
  //rootSection
  
  &lt;@property key="eventID-rootsection" /&gt; 
  //32465
  
  &lt;#assign eventID = &lt;@property key="eventID-${sectionName}" /&gt; &gt;
  //syntax error
  </code></pre>
