Use this Rational ClearCase preference option to specify ClearCase behavior when WebSphere Studio edits, in a non-interactive manner, a file that is not currently checked-out. For example, the process of refactoring can cause several files to be changed non-interactively. ClearCase performs the selected behavior when it detects that WebSphere Studio is trying to edit the file.
Select Automatically checkout if you want ClearCase to automatically check the file out without notifying you. Select Do nothing if you do not want ClearCase to automatically check the file out when it detects that the file you are trying to edit is not checked out.
