body: <p>I am stuck in one place. i developing an extension in typo3. I used flexform for admin.
  Now I try to fetch that flexform value in controller for backend module but i get "Null" every time. Same value i try for frontend module that time i can fetch value.</p>
  
  <p>Below is my flexform code:</p>
  
  <pre><code>&lt;T3DataStructure&gt;
      &lt;meta&gt;
          &lt;langDisable&gt;1&lt;/langDisable&gt;
      &lt;/meta&gt;
      &lt;sheets&gt;
          &lt;sCategorybox&gt;
              &lt;ROOT&gt;
                  &lt;TCEforms&gt;
                      &lt;sheetTitle&gt;XY&lt;/sheetTitle&gt;
                  &lt;/TCEforms&gt;
                  &lt;type&gt;array&lt;/type&gt;
                  &lt;el&gt;
                      &lt;settings.cat1&gt;
                          &lt;TCEforms&gt;
                           &lt;exclude&gt;1&lt;/exclude&gt;
                           &lt;label&gt;XYZ&lt;/label&gt;
                           &lt;config&gt;
                            &lt;type&gt;select&lt;/type&gt;
                              &lt;renderType&gt;selectMultipleSideBySide&lt;/renderType&gt;
                              &lt;size&gt;5&lt;/size&gt;
  
                              &lt;foreign_table&gt;tx_myext&lt;/foreign_table&gt;
                              &lt;foreign_table_where&gt; AND tx_myext.hidden = 0 AND tx_myext.deleted = 0 ORDER BY name ASC&lt;/foreign_table_where&gt;
                           &lt;/config&gt;
                          &lt;/TCEforms&gt;
                      &lt;/settings.cat1&gt;
                  &lt;/el&gt;
              &lt;/ROOT&gt;
          &lt;/sCategorybox&gt;
      &lt;/sheets&gt;
  
  &lt;/T3DataStructure&gt;
  </code></pre>
  
  <p>In Controller's action i tried like this <code>$this-&gt;settings['cat1'];</code></p>
  
  <p>Flexform is used for the backend where admin can select category when admin add extension to page.</p>
  
  <p>extension also have backend module and seprate action for backend module, I want that selected category value in that action.</p>
