Javascript error can be thrown on browser's console when accessing a page containing the Form widget



      Hypothesis: this issue is intermittent. It only occurs when a particular set of characters, that represents the instanceId of the Form widget, is translated to a hash number that makes the JavaScript of that widget to be printed before the instantiation of the object Liferay.Session. So, in order to facilitate reproduction, I've exported a site containing two identical pages: one broken and another working.

      Note: the content of the exported site is a form with auto-save disabled and two widget pages containing, each one of them, a Form widget displaying the only form of the site.

      Steps to reproduce:

      1. Go to Site's Publishing > Import;
      2. Create a new import process and select the attached .lar file corresponding to the Liferay version you're testing;
      3. Once the process finishes successfully go to the "Bad Page": http://localhost:8080/web/guest/bad-page;
      4. Open the browser console and refresh the tab.

      Expected behavior:
      No error is thrown on browser's console.

      Actual behavior:
      The following error is thrown on the browser's console:

      Uncaught TypeError: Cannot read property 'get' of undefined

      It might take using incognito mode and/or restarting the server.
