title: Failed to load 'sap/ui/table/TreeTable.js'
body: <p>I'm trying to create a tree structure view from a json model using SAPUI5.<br>
  I haven't found solutions on the internet so this is why I'm asking here. <br>
  Basically, despite having used the right code over and over again, It fails to load the TreeTable.js file, I have tried using multiple codes but no luck. <br>
  I am loading the TreeTable on a Dialog. This is the code:</p>
  <pre><code>&lt;core:FragmentDefinition 
  xmlns=&quot;sap.ui.table&quot;
  xmlns:mvc=&quot;sap.ui.core.mvc&quot;
  xmlns:m=&quot;sap.m&quot;
  xmlns:u=&quot;sap.ui.unified&quot;
  xmlns:core=&quot;sap.ui.core&quot;&gt;
  &lt;m:Dialog horizontalScrolling=&quot;true&quot; showHeader=&quot;true&quot; state=&quot;None&quot; stretch=&quot;false&quot; title=&quot;{Soluzione}&quot; type=&quot;Standard&quot; verticalScrolling=&quot;true&quot; contentWidth=&quot;90%&quot;&gt;
      &lt;m:content&gt;
          &lt;TreeTable
          id=&quot;Tree&quot;
          rows=&quot;{path: 'applicationModel&gt;/AlberoSoluzioni'}&quot;
          selectionMode=&quot;MultiToggle&quot;
          enableSelectAll=&quot;false&quot;
          ariaLabelledBy=&quot;title&quot;&gt;
              
          &lt;/TreeTable&gt;
      &lt;/m:content&gt;
      &lt;customHeader/&gt;
      &lt;endButton/&gt;
      &lt;subHeader/&gt;
  &lt;/m:Dialog&gt;
  &lt;/core:FragmentDefinition&gt;
  </code></pre>
  <p>Wondering what I'm doing wrong.
  Error in console at loading:</p>
  <pre><code>Uncaught Error: failed to load 'sap/ui/table/TreeTable.js' from resources/sap/ui/table/TreeTable.js: 404 - Not Found
  </code></pre>
