Editing a Project works by making a copy of the Project, allowing the user to modify the copy, saving the copy and, finally, loading the Project, which involves replacing the Project with the modified copy. This mechanism allows a partially edited Project to be saved without any affect on the original Project.
Only when the
Save & Load
option is selected, an attempt is made to commit the changes to the Project. If the Load fails for any reason, the original Project is restored to its original, pre-Load condition. The edited copy of the Project is kept so that the user can re-edit the Project, correct the error and try the Load process again.
If
Save
was selected at the end of the last Edit Session, or if an error occurred when
Save & Load
was last selected, then the next time the
Project
Edit
option is selected the following dialog will be displayed:
Choose the Continue editing option to carry on editing where you left off previously. Or choose
Restart
editing to discard your earlier changes. Choose this option with care.
After
Save & Load
, before re-running Clustering tasks, you must re-initialize the database to remove records from previous runs. Any alterations, which you make to the Project using the Project editor, will NOT be reflected back to your
.sdf
text file. In other words, this action only affects the Projects currently contained in the Rulebase.
