title: TYPO3 Frontend Error: The ViewHelper "<v:switch>" could not be resolved
body: <p>Trying to open a site including a html-file from my extension, this error occures: (TYPO3 Version 8.7.19)</p>
  
  <pre><code>1407060572: Fluid parse error in template 
  partial_Video/VideoSlide_016cfc0cd210899384d5d10b02b3336b438691df, line 47 at 
  character 1. Error: The ViewHelper "&lt;v:switch&gt;" could not be resolved. Based on 
  your spelling, the system would load the class 
  "FluidTYPO3\Vhs\ViewHelpers\SwitchViewHelper", however this class does not 
  exist. (error code 1407060572). Template source chunk: &lt;v:switch value=" 
  {fegroup.uid}"&gt;
  </code></pre>
  
  <p>According to the error message, there is a problem with the Viewhelper and the switch statement.</p>
  
  <p>Here is the using namespace</p>
  
  <pre><code>{namespace v=FluidTYPO3\vhs\ViewHelpers}
  </code></pre>
  
  <p>and here is the code of the switch statement:</p>
  
  <pre><code>&lt;f:if condition="{v:variable.get(name: 'access', useRawKeys: 1)}"&gt;
      &lt;!-- ... --&gt;
      &lt;f:else&gt;
          &lt;f:for each="{video.fegroupUID}" as="fegroup" iteration="iterator"&gt;
              &lt;v:switch value="{fegroup.uid}"&gt;
                  &lt;v:case case="2" break="TRUE"&gt;
                          &lt;div class="thumbnailcontainer_overlay"&gt;
                              &lt;p&gt;&lt;f:translate key="thumbnail_justforregisteredusers"/&gt;&lt;/p&gt;
                          &lt;/div&gt;
                  &lt;/v:case&gt;
                  ...
  </code></pre>
  
  <p>No matter what I change, I always get the same error, like shown above. Even when I comment out the responsible Partial, which confuses me a lot!
  I allready cleared all chaches(in Install Tool), tried other namespaces and doublechecked my switch statement.</p>
  
  <p>Thanks in advance!</p>
