Examples

Character Restriction in Form Validation

You can use the NOT function in an Output Validation formula to ensure a user does not enter prohibited characters into a text field.

• Scenario: You have a "Username" field that must not contain any spaces.
• Formula: ASSERT(NOT(REGEX_MATCH(this, / /)), "Usernames cannot contain spaces.").
• Logic:
  • REGEX_MATCH(this, / /): This part of the formula returns TRUE if a space is found in the current text.
  • NOT(...): The NOT function reverses that result. If a space is found (TRUE), NOT makes the result FALSE.
  • ASSERT: In GoApprove validation, a FALSE result triggers the error message, informing the user that spaces are disallowed.

Conditional Path Routing Based on Status

The NOT function can be used in a Path Condition formula to route an approval based on whether a previous activity was not successful.

• Scenario: A workflow includes a "Safety Inspection" activity. If the inspection is not completed (e.g., it was cancelled or expired), the workflow should follow a "Failure Log" path.
• Formula: NOT(@SafetyInspection.prop.Completed).
• Logic:
  • @SafetyInspection.prop.Completed: This system property returns TRUE if the activity was finished and FALSE otherwise.
  • NOT(...): If the activity is incomplete (FALSE), the NOT function turns it into TRUE.
  • Result: Because the path condition is now TRUE, the branch follows the designated path for incomplete inspections.
