Exception when registering a custom set function

[mdrozdo]

Description:
When trying to register a custom set function the SetFunction.getXXInstance method throws an exception due to not finding the function name in the internal map.

Affected Product Version:
All

OS, DB, other environment details and versions:
All

Steps to reproduce:
Call
SetFunction.getSetEqualsInstance("functionName", "anyDatatype")
Function throws

IllegalArgumentException("unknown set function functionName")

I suppose the ConditionSetFunction constructor should call getId on function type not function name (see below). but I haven't tested it.

public ConditionSetFunction(String functionName, String datatype, String functionType) {
		super(functionName, getId(functionType), datatype, BooleanAttribute.identifier, false);
	}
