Manual lock mode
When the manual lock mode option is selected in Talend Administration Center, you cannot lock any item, unless intentionally.
To intentionally lock an item (for edition purpose for example), simply right-click it and select the Lock option while the item is in the closed state.
The same way, a locked item can only be unlocked through the same procedure by the lock owner (or through Talend Administration Center web application by the administrator).
By default, items can only be opened in read-only in this manual lock mode.
