  5. Empty variables should not be used in actions that throw null pointer exception

Empty variables should not be used in actions that throw null pointer exception

Introduced in version: 1.3 (29 Jan 2020)

  • Change Object
  • Show Page
  • Export
  • Import
  • REST/WebService
  • Generate document
  • Download document
  • Validation feedback
