How to get a rule property using decision engine ?
I have an existing code with the following b2x code to retrieve rule property using classic rule engine (CRE) :
String val = new String();
if (instance.getRule().properties.get(propName) != null)
val = (String) instance.getRule().properties.get(propName).getValue();
return val;
When migrating to DE I get below error :
GBREM0010E: Cannot migrate invocation of method ilog.rules.factory.IlrPropertyList.Entry.getValue(), no corresponding method found in type java.lang.Object model.b2x
How can I do the same using DE ?
Accepted answer
You need to use below b2xa code in ARL :
java.lang.String val = new java.lang.String();
if (com.ibm.rules.engine.ruledef.runtime.RuleInstance.this != null)
val = (java.lang.String) com.ibm.rules.engine.ruledef.runtime.RuleInstance.this.getRule().getProperties().get(propName);
return val;
