created jira 3270 for this.

Also created 3271 along the same lines.

You'll need to raise a JIRA for an enhancement.

Dependent enumerations are currently only designed to operate between enumerations.

With kind regards,

I am trying to use data enumerations and running into a problem. Following the Vehicle engineType/fuelType data enumeration example in the Guvnor manual, I created the following enumeration list and it works:

'Vehicle.engineType' : (new test.VehicleHelper()).getEngineTypes()
'Vehicle.fuelType[engineType]' : '(new test.VehicleHelper()).getFuelTypes("@{engineType}")'

VehicleHelper:
------------

public class VehicleHelper {
       
        public List<String> getEngineTypes(){
                List<String> engineTypes = new ArrayList<String>();
                engineTypes.add("Petrol");
                engineTypes.add("Diesel");
                return engineTypes;
        }
       
        public List<String> getFuelTypes(String engineType){
                List<String> fuelTypes = new ArrayList<String>();
                if("Petrol".equalsIgnoreCase(engineType)){
                        fuelTypes.add("ULP");
                        fuelTypes.add("PULP");
                }
                else if("Diesel".equalsIgnoreCase(engineType)){
                        fuelTypes.add("BIO");
                        fuelTypes.add("NORMAL");
                }
                else{
                        fuelTypes.add("Default Fuel 1");
                        fuelTypes.add("Default Fuel 2");
                }
                return fuelTypes;
        }

}

Above works as expected.

Problem:

I want to only have an enumeration on Vehicle.fuelType that depends on the value of engineType, without specifying an enumeration on engineType. So, I took out the first line in my enumeration list so that it is now:

'Vehicle.fuelType[engineType]' : '(new test.VehicleHelper()).getFuelTypes("@{engineType}")'

But that does not work. When I create a rule, VehicleHelper.getFuelTypes does not get called and the dropdown for fuelType is not a list.

How do I get this working?

Thanks
