title: TYPO3 fluid variables
body: <p>I upgrade my TYPO3 from 7.6 to 8.6.
  Now I cant set variables via style.content.get, my root template loads fluid_styled_content. 
  some source:</p>
  
  <pre><code>page.10 = FLUIDTEMPLATE
  page.10 {
      partialRootPath ={$resDir}/Private/Partials
      layoutRootPath = {$resDir}/Private/Layouts
  
     variables {
          contentMain &lt; styles.content.get
          contentMain.select.where = colPos = 0
          contentnew &lt; styles.content.get
          contentnew.select.where = colPos = 1
          contentkat &lt; styles.content.get
          contentkat.select.where = colPos = 2
  
          test = TEXT
          test.value = loool
      }
  }
  </code></pre>
  
  <p>display the variables:</p>
  
  <pre><code>&lt;f:format.raw&gt; {contentMain} &lt;/f:format.raw&gt;
  &lt;f:format.raw&gt; {contentnew} &lt;/f:format.raw&gt;
  &lt;f:format.raw&gt; {contentkat} &lt;/f:format.raw&gt;
  &lt;f:format.raw&gt; {test} &lt;/f:format.raw&gt;
  </code></pre>
