Validate a Decision Table In TIBCO BusinessEvents WebStudio, you can validate decision tables for the changes using the validate command. Select the decision table and click on the validate icon to validate the table. The validate icon is activated when the decision table is opened in the editor. EAR file for the project should be present in the deploy location; otherwise, validate command gives error. If there are any access control violations or syntax errors in the tables, they are shown in the Problems View tab at the bottom of the application. New errors in syntax are added to these existing errors. Double-click errors to see the problematic view. Take any needed corrective actions and then validate the table again until all errors are resolved.
