I will see if it's working for my more difficult case. On Tue, Mar 1, 2011 at 11:28 PM, Esteban [via Drools - Java Rules Engine] <[hidden email]> wrote: 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?

And for attributes of that object in DSL i can define values that can take this attribute? Maybe i don't understand but i don't see how to do with this. My case : I have Maps in the session. Each Map has for example 5 properties ("prop1", "prop2", "prop3", "prop4", "prop51") and the value is a string. The Map is Map<String, Object> but generally Object is a String. So in the When clause i have something like that : $m : Map((this["prop1"] == "test1")) I have included java.utils.Map in Guvnor. So when i add a when clause i can choose Map in the list but impossible to have "prop1" to "prop5" in a drop down list for attributes of the Map. Would it be possible to create a Pojo for Map or would it be in conflict with the Map of Java?

In fact in my map i know all the properties (about 200). It would be cool to be able to have a drop down list with all these attributes as when we do it with objects for which we gave Pojo to Guvnor. You can define enumerations for a particular attribute. Inside a DSL you can constrain a placeholder with that enumeration. And finally, enums can be static, or dynamic (a interface to implement that returns a list of values). search the Guvnor's doc in these chapters 1.4.2.4.8.
