title: Choose File Robot Framework not uploading file
body: <p>I am developing a scenario where a file is uplodaded using the <code>choose file</code> robot framework keyword.  The test runs and when the choose file executes, it hits the locator for the <code>&lt;input type="file"&gt;</code> element, the UI shows a red box at the bottom of the page (see attachment), but the file is not uploaded.</p>

  <p>Im not sure if the UI doesn't know how to handle the upload, or if there is an error in my code:</p>
  
  <pre><code>choose file  xpath=/html/body/div/div/div/div[2]/div/div/div/div/div/div/div/div/div[1]/div[1]/div[2]/div/span  ${dataDir}studentSAT.csv
  </code></pre>
  
  <p>The <code>${dataDir}</code> variable contains the OS full path to the file, and the file is at that location.  As a point of validation, I tried changing the filename to one that is not present, and robot throws an error stating data not available.</p>
  
  <p>Has anyone encountered this before?</p>
