Some error in some java-code looking for column subRegion_Account in entity Administration. Administration being a standard any often used module, so not likely that the module Adminstration is causing this. Does your application use module Administration? You either have, or you have created a custom module Administration. You have added entity Region and associated it to Account, named the association subRegion_Account. Created a Java widget that takes one or more arguments, one of them being a string which is supposed to receive the name of one of the columns of entity Administration.Account. Yet, when calling that java-widget, ‘Administration.subRegion_Account’ was passed along. Just rambling here, may be totally missfiring. Hope it helps a bit.
