I have created a new attribute (as part of a category) in xECM. Normally, such a new attribute would appear automatically in the 'Regions' overview (Admin —> Content Server Administration —> System Object Volume —> Enterprise Data Source Folder —> right click on menu of 'Enterprise Search Manager —> select 'Properties' —> 'Regions'.
Now, this new attribute does not appear. What can be the cause of this issue?
