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
