Problems and solutions

Troubleshooting around rules – why a rule does not run, does not compile or a BO is not in the context.

Common pitfalls around rules and business objects – with causes and remedies.

Rule is not executed

Rule not set to active in the editor.
Rule contains compile errors and cannot be built as a class.
Rule built but not assigned to a business object.
Rule assigned to the wrong BO: a rule on the BO order item does not run when editing an order, even if items appear as a subform.
No status specified in the assignment – records with a special status (e.g. „cancelled“) are skipped. Also applies to actions.

The class structure does not match the Java syntax.
The import of the business object class is missing.
Business objects have not yet been generated – they are created when the BO is processed according to its metadata.

Only the BO the rule is assigned to is in the context. If the rule is attached to the order, getBusinessObject(Customer.class) cannot work.
