Notes on diagrams

The following points should be kept in mind about diagrams:

• When a user begins editing a diagram, a lock us set. No other user can edit it until the diagram changes are saved, the user closes the Diagram Editor, or the lock timeout occurs. The duration of the lock before it times out is set by the system administrator in the system configuration.

  See: Advanced System Tuning (com.polarion.ui.lock.timeout).

• If the Duplicate Work Item function is invoked while a diagram is being edited, pending changes to the diagram are saved before the Work Item is duplicated. Subsequent changes to the diagram after the Work Item has been duplicated will not be reflected in the new, duplicate Work Item.

• Changes to diagrams in Work Items are tracked in the Work Item history. That is, if the only change to the Work Item is a diagram change, the revision of the Work Item in which the change was made contains the diagram in the state it was when the Work Item was saved. Changes to a diagram are not saved to the history until the Work Item is saved.
