Hi,
I have been running more test cases on Drools-Guvnor, 5.1.0.M2, and I found a solution for
the question 3) I had on my initial email thread.
As for the 1), and 2), here is more context, hope that will help in debugging/solving my
issues, as I am stuck at this point.
1) I need to create a BRL with the IN conditional element for the Fact field that is Text
type.
I can do that when creating a technical rule, but I see no option for the BRL with guided
editor. The option for the text fields are (equals, not equal, matches, sounds like).
However, even with the technical rule there seem to be some issues. First, I can compile
and verify the technical rule OK, but when I ran a test for the technical rule, I got an
error that I pasted below. Here is the technical rule with the IN condition:
when
#conditions
$assignmentRule:
RequestItemAssignmentRule(approvalLevel=="Approval_Level_1")
Attribute(code=="EQUIPMENT_FAMILY",uvalue in
("200","300"))
then
#actions
modify ($assignmentRule){assignTo="admin",
assignToId="394394993"}
The error when I ran the test for this technical rule, is:
Error: Unable to determine the used declarations.
java.lang.Class cannot be cast to org.mvel2.util.MethodStub
2) I have a decision table manually created, that is using for one of the conditions this
formula (with FROM and IN for the field):
Attribute(code=="DISCIPLINE" && uvalue in ($param)) from
assignmentRule.getAttributes()
The drools engine loads the decision table and executes it correctly in the app.
What I try to do, is to create a decision table in Guvnor, using the guided editor, and
set the same condition for one of the fields. But I cannot find how to do this. On the
editor, it says that I can use Predicate in order to evaluate an expression and use
$param, but when I select the "Predicates" option on the editor, it says for
both Field and Operator that "(not needed for predicate)", and I cannot enter
anything.
What am I doing wrong? I appreciate a lot for any insight/hint, or solution.
Thanks,
Patricia

Hi,
I am evaluating Drools Guvnor for our application, and I am stuck with a few things. I
appreciate a lot, if someone can help me, or give me some hints.
1) How can I
configure Guvnor, BRL Guided Editor, to allow for IN conditional element?
By default, when I create a new package, and then create a new BRL rule, I have these
options for a text Fact field:
- equal
- not equal
- matches
- sounds
I do have the IN conditional element for the Decision Table rule - "is contained in
the a (comma separated) list".
2) How can I configure Guvnor, Decision table, to use the FROM condition element?
I have a fact, Fact1, that contains a list of Fact2. The condition I need to configure in
the Decision Table, is to iterate the collection of Fact2 objects that is on the Fact1,
and apply constraints on Fact2 fields.
3) How
can I insert a list of facts when testing a rule? My test case is the following:
I have a Fact1, which contains a list of Fact2. And the rule, is expecting to get Fact1,
with a list of Fact2 inside.
When I create the Fact1, and add the collection field, it shows the option to create a
guided list where I can specify a literal value, or a variable. But there is nowhere to
create a Fact2 with its fields. I did inserted 2 separate Fact2 objects, but how I can
link these 2 objects to the collection of the Fact1?
Thanks in advance,
Patricia
