Gilad Chaplik has submitted this change and it was merged. Change subject: frontend: ConcurrentModificationException in AdElementListModel ...................................................................... frontend: ConcurrentModificationException in AdElementListModel The exception occured in the populateRoles method when user is adding permissions to the VM in permissions subtab. The problem is introduced by refactoring in 05c06da3 and is only visible in gwt-debug console. The problem was caused by removing items from the list in the for-each loop. Fixed by introducing a copy of the modified list (to avoid modifying the collection passed in the argument).
