You can customize rule model with Model extension and add your custom property (YOUR_PROPERTY_NAME) to the rule artefact.
You can acces this by adding a virtual method (static method in the BOM! don't use a xom! simply add it with the BOM editor) verbalized YOUR_VERBALISATION.
- In the method implementation (B2X), you can get the value with the
instance.getRule().getPropertyValue("YOUR_PROPERTY_NAME")
; (instance is a runtime variable containing theIlrRuleInstance
of the current Rule) - In the action part use YOUR_VERBALISATION to call the method.
