Re: [rules-users] Guvnor and drools implementation - questions

"Maps.properties" is just a name I choose for the enumeration. You can use whatever identifier you want, but..... The identifier has to be of the form <string>.<string>. It has to have a dot (.). I think this is because enumeration were created for bind a fact type attribute to a list of values.
