How to reload editor preview window Follow

I guys, I have attached a small screencast, in which I convert a Markdown document to AsciiDoc. The Markdown has a preview tab, and so has the AsciiDoc document, but after the Markdown document is converted to AsciiDoc, I still see the preview window of the Markdown file, but it's trying to render the AsciiDoc, which fails. When I close the newly converted document and reopen it, then I can succesfully preview the contents of the AsciiDoc.

I'm using the following code for the conversion:

  ApplicationManager.getApplication().runWriteAction(new DocumentRunnable(document, project) {
    @Override
    public void run() {
      CommandProcessor.getInstance().executeCommand(project, new Runnable() {
        @Override
        public void run() {

          if (document != null) {
            try {
              String newFileName = FilenameUtils.getBaseName(file.getName()) + ".adoc";
              virtualFile.rename(this, newFileName);

              document.setText(AsciiDocProcessor.convertMarkdownToAsciiDoc(file.getText()));
            }
            catch (IOException e) {
              e.printStackTrace();
            }
          }
        }
      }, getName(), getGroupId(), UndoConfirmationPolicy.REQUEST_CONFIRMATION);
    }
  });
}

But I guess I need to inform IntelliJ that in some way it should reload the preview screen? How can I do such a thing? Or is my document renaming (and document text replacement) incorrect?

Thanks,

Erik
