Last Error Info
Flowgear Workflows support both Run Now and Always On execution modes. Run Now allows for on-demand use by a user or API call while Always On allows for Workflows that contain Triggers and execute continously. Users indicate which of these options is available from the Workflow Design Settings Pane.
