When attempting to Edit a Page with a Portlet, the following error occurs in the Portlet area:


ERROR

Remote Portlet Error

 

Trying to edit the Portlet Style results on the following error:

STEPS

The issue can be reproduced at will with the following steps:

  1. Add the portlet to a page.

  2. Publish the page draft.

  3. View the page and confirm the portlet looks fine.

  4. Edit the page.
    Here you will see the following error:

    Remote Portlet Error


  5. Select the Portlet in the page.
    Then from the Portlet View Actions Menu select: Content Style

    This will return the Internal Error

    After this, the page will always return Internal Error until you delete the page draft.
