I created a new relationship based on Manager-Employee. Created a new instance of the Org Chart portlet and changed the
relationship used to the newly created one. Finally I added a new page to display the org chart. So far no problems.

Now, a couple of days later I removed the page, removed the new instance of the org chart portlet and finally removed the

After that one of the cluster nodes shows the folling error when trying to access the standard org chart page:
Error occurred, the Virtual Relationship Definition was null for key manager2manager

Why? I never altered the standard org chart portlet or page.

Best regards,
