When attempting to drag objects between clients in the v12 Java GUI, a user receives the following error:
U00000009 '': Access denied
This happens with a user with full authorizations and privileges
This is due to a change in the internal permissions for drag and drop, as the focus was shifted in v12 to the AWI over the deprecated Java UI
The issue was found and fixed with:
Automation.Engine 12.0.8 in Initialdata - released 5-6-2019
Hotfix-Description: Access is denied when moving an object from one client to another
A problem has been fixed where dragging and dropping an object from one client to another produced the error message "Access denied".
