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

You need to create the DSL first. Follow these steps: 1.- Add java.util.Map to package imports (I think you already did this) 2.- Create a new Enumeration with the following content: *'Map.properties': ['prop1', 'prop2', 'prop3']* 3.- Create a new DSL with this content: *[when]The property {key:ENUM:Map.properties} of the map is {value}=Map((this["{key}"] == "{value}"))* 4.- Create a new Rule and add the DSL sentence to the WHEN part. You should see the drop down. Note the name of the enumeration and how the variable {key} is defined in the DSL. I think you can also read the enumerations from a Java Enum present on your model, but I'm not sure about it. Does anyone know about this?
