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

I don't think that enums needs to be linked to a Pojo attribute. To me it is just an identifier used in ENUM DSL constraints. The 'properties' is not an attribute of a Map. I think you could set it to whatever you like (something more linked to your problem). For making that dynamic, it is explained in the guvnor doc<http://drools.herod.net/drools-guvnor/html_single/index.html>(c... "1.4.2.4.8. Data enumerations (drop down list configurations)" ) 'Person.age' : (new com.yourco.DataHelper()).getListOfAges() But I never tried that.
