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).<br>
<br>
For making that dynamic, it is explained in the <a
href="http://drools.herod.net/drools-guvnor/html_single/index.html">guvnor
doc</a> (<a moz-do-not-send="true" rel="nofollow" target="_top">
chapter "1.4.2.4.8. Data enumerations (drop down list
configurations)" )</a><br>
<pre class=""><a id="d0e909">'Person.age' : (new com.yourco.DataHelper()).getListOfAges()</a></pre>
<br>
But I never tried that.<br>

<div class="im"> 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>

<blockquote class="gmail_quote" style="border-left: 2px
solid rgb(204, 204, 204); padding: 0pt 1em;"> 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 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>
