Key Concept - Server - 'Set Redirect URL' Function - Use the Debug Now UI Action to debug scripts from table sysauto_script (“Scheduled Script Executions”) with syntax highlighting and breakpoint capabilities. - Use action.setRedirectURL(current) in a UI Action, to keep the user on the very same web page after any UI action is executed.

Name -Debug Now Table -Scheduled Script Execution [sysauto_script] checked; active, show insert, show update, Form button« Comments -Runs a scheduled script execution script in the current session so that it can be debugged using the script debugger, and also so that messages pushed up to the client may be displayed

Hint -To hit breakpoints, be sure to launch the Script Debugger BEFORE clicking this Debug Now button
