Optaplanner JAXB
by Jugu Dannie
The optaplanner uses XStream for reading the solver configuration from XML.
For using JAXB instead, is it sufficient to have custom implementation of
XMLSolverFactory and SolverConfig?

Formula in Decision Table?
by nzhu972
Can someone confirm if I am using Formula the correct way in a web based
decision table?
I like to populate the Condition Columns automatically when certain other
columns in the Condition Columns are populated.
For example, If col1 and col2 are populated, can I use formula to auto
populate col4 with value X and if col1, col2 and col3 are populated, then
auto populate col4 with Y?
If Formula isn't the right approach, is auto populating possible for web
based decision table in Drools 5?
Thanks

bound variable scope
by webfrank
Hi,
I have a rule with a "from accumulate" where I bind "e" variable to Event
object. I would like to pass "e" to
send method of channel like: channels["reset"].send(e); but I got a Rule
Compilation error with: "e cannot be resolved". Why I cannot access variable
"e" when defined inside from accumulate?
rule "Reset alarm"
when
a : Alarm()
c : Number( intValue > 5) from accumulate (
e : Event( level < 6) over window:time(10s) from entry-point "queue",
count(e)
)
then
channels["reset"].send("Alarm resolved.");
end

Insert fact to be used as semaphore
by webfrank
Hi everybody, I'm new to drools and I would like to solve this simple
situation:
I have a rule which will fire when 3 or more events comes from entry-point
with level > 4 in a 10s window:
rule "Got 3 events"
when
not Alarm()
t : Number(intValue > 2) from accumulate (
e : Event( level > 4) over window:time(10s) from entry-point "queue",
count(e)
)
then
insert(new Alarm());
end
This way if more events comes with level > 4 no more alarms are sent.
I have another rule to retract Alarm object when more than 5 events comes
with level < 6 in a 10s window:
rule "Reset alarm"
when
a : Alarm()
c : Number( intValue > 5) from accumulate (
e : Event( level < 6) over window:time(10s) from entry-point "queue",
count(e)
)
then
retract(a);
end
The problem is that I got an infinite loop once I retract the Alarm object
and a new is inserted by the first rule.
How could I solve the problem? Probably a different approach but I'm still
learning.

Guvnor Data Enumeration
by nkhogen
In the Advanced Data Enumeration in Guvnor, it is possible to define list of
values for a field by fixing value on another field as follows
ZipCode, field1 = "55000", field2 = ['1','2','3']
ZipCode, field1 = "66600", field2 = ['10','20','30']
ZipCode is the fact class, field1 and field2 are its members.
But if I have something like
ZipCode, field1 = "OTHER", field2 value should not be bound. I should be
able to fill anything. But, Guvnor does not allow it once field1 is bound to
something else.
Please let me know if anyone has had this issue before.
