title: #1237900529: The argument "each" was registered with type "array", but is of type "string" in view helper "TYPO3\CMS\Fluid\ViewHelpers\ForViewHelper"
body: <p>I get the following error message <strong>#1237900529: The argument "each" was registered with type "array", but is of type "string" in view helper "TYPO3\CMS\Fluid\ViewHelpers\ForViewHelper"</strong> while trying to iterate through the rows of my data using the following FLUIDTEMPLATE (FT) iteration:</p>
  
  <pre><code>&lt;h2&gt;Sources&lt;/h2&gt;
  &lt;f:for each="{content_source}" as="source"&gt;
      &lt;p&gt;{source.header}&lt;/p&gt;
  &lt;/f:for&gt;
  
  &lt;h2&gt;Contact&lt;/h2&gt;
  &lt;f:for each="{content_contact}" as="contact"&gt;
      &lt;p&gt;{contact.header}&lt;/p&gt;
  &lt;/f:for&gt;
  </code></pre>
  
  <p>I'm running Typo3 6.2.14 and would like to parse this HTML to match with BootStrap's architecture in my custom built template. I don't have much knowledge on Typoscript &amp; FT; it is however preferable for me to use FT over TypoScript to make conditions for html parsing. What should I adjust if I have the following TypoScript:</p>
  
  <pre><code>10 = FLUIDTEMPLATE
  10{
      file= fileadmin/Templates/index.html
      layoutRootPath = fileadmin/Templates/layouts/
      partialRootPath = fileadmin/Templates/partials/
      variables {
          content_source &lt; styles.content.get
          content_source.select.where = colPos=3
          content_contact &lt; styles.content.get
          content_contact.select.where = colPos=4
      }
  }
  </code></pre>
