title: TYPO3: Condition "if column empty"?
body: <p>I'm looking for a condition to check wether a certain column is empty.</p>
  
  <p>Something like this:</p>
  
  <pre><code>[colPos.0 = empty]
  #do stuff
  [global]
  </code></pre>
  
  <p>Thanks in advance.</p>
  
  <p><em>Edit:</em><br>
  I think it's quite unclear what I'm looking for. So let me add some information:</p>
  
  <p>I've got a column for a teaser image in the BE (colPos = 0). If it contains an element, it should regularly display this element. If not (== if empty), it should use another image instead.</p>
