HI rev,

    // The following options are available for resetting the approvals:

          //

          // 1. Mark all existing approvals for the change as 'cancelled' and

restart the workflow to create new approvals

          //             new WorkflowApprovalUtils().cancelAll(current, comment);

          //             new Workflow().restartWorkflow(current);

          //

          // 2. Delete all of the existing approvals for the change and restart

the workflow to create new approvals

          new WorkflowApprovalUtils().reset(current, comment);

          gs.addInfoMessage('Workflow has been reset since key fields have been

modified');

          //

          // 3. Leave the approvals for the change in their current state and

restart the workflow.

          //       (so that any new approvals that are required will be created)

          //             if (comment)

          //                   current.setDisplayValue('approval_history', comment);

          //             new Workflow().restartWorkflow(current, true);

          //

    }
