Title: CARTE DE VISITE
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 (
chapter "1.4.2.4.8. Data enumerations (drop down list
configurations)" )
'Person.age' : (new com.yourco.DataHelper()).getListOfAges()
But I never tried that.

Really thank you, it's working fine. I will see if
it's working for my more difficult case.

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?
Yes but for
this i will be obliged to create a POJO of an object. 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?
Thank you for your time

Thanks for your quick answer
Esteban.
1) Ok i will have a look at DSL. 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).
