Really thank you, it's working fine.

You need to create the DSL first.<br>Follow these steps:<br>1.- Add java.util.Map to package imports (I think you already did this)<br>2.- Create a new Enumeration with the following content:<br><b>'Map.properties': ['prop1', 'prop2', 'prop3']</b><br>
3.- Create a new DSL with this content:<br><b>[when]The property {key:ENUM:Map.properties} of the map is {value}=Map((this["{key}"] == "{value}"))</b><br>4.- Create a new Rule and add the DSL sentence to the WHEN part. You should see the drop down.<br>
<br>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?<br>

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?<div><div></div><div class="h5"><br>
Maybe i don't understand but i don't see how to do with this.<br>
<br>
My case :<br>
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.<br>
So in the When clause i have something like that :<br>
<font color="#000099">$m :
Map((this["prop1"] == "test1"))</font><br>
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.<br>
Would it be possible to create a Pojo for Map or would it be in
conflict with the Map of Java?<br>
<br>
Thank you for your time<br>

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. <br>

You can define enumerations for a particular attribute. <br>
Inside a DSL you can constrain a placeholder with that
enumeration. <br>
And finally, enums can be static, or dynamic (a interface to
implement that returns a list of values).<br>
<br>
search the Guvnor's doc in these chapters<br>

enumerations (drop down list configurations)</a></h5>
