hi -
i am using drools-distribution-5.2.0.M2. Here is the drl i am using -
----------
dialect "mvel"
import com.deltadental.drools.sample.*
rule "Rule 01"
when
$underageCustomer : Customer(dob>"15-May-1993")
$order : Order(customerId == $underageCustomer.customerId)
eval($order.discountPercentage == 0)
then
$order.discountPercentage = 25;
System.out.println("Rule 01 fired. Applied discount
"+$order.discountPercentage);
end
------------------
I get a RuntimeDroolsException: Exception executing predicate dob >
"15-May-1993"
Caused by: java.lang.RuntimeException: uncomparable values <<Mon May 01
00:00:00 EDT 2000>> and <<15-May-1993>>
caused by a class cast exception - String cannot be converted to a Date.
I get the same exception with 5.1.1. I tried the same setting Locale and
drools.dateformat properties - no luck so far..
Am I missing something here?
Thanks
Muk

I got this test case to work with Drools 5.1.1 - but I think the latest 5.2
distribution has an issue with date comparision.

Code like this works with both versions. Can you please provide a complete
(reduced) example
producing the error?

New subject: Is there a "extends" for the "declare" of a new type?
Hi,
I have tried to look this up but cannot find any clear answer on the web.
Does drools support extension of existing classes for new type declarations?
That would be very nice if this would be possible.

There is, since 5.2.0, the option of extending a class declared in DRL:
declare A
i : int
end
declare B extends A
...
end
Any class origninating from Java code cannot be extended in DRL.

Wolfgang,
I think Davide's implementation supports extending existing java
classes... did you tried? What is not possible is to implement interfaces,
since you can't define methods in the declare statement.

This is what's in the unit test "test_ExtLegacy.drl":
declare BetterLegacy extends LegacyBean
// novel field
oneMoreField : String = "Hello"
// inherited fields redeclared to set initial value
doubleField : Double = 3.3 @position(1) // tag
inherited field, will be 1st field
strField : String = "XX"
intField : int = 245
prop : boolean = true
// objField is not redeclared
end
and this one "test_Extends.drl"
declare Person
age : int = 99 @position(2)
name : String = "john doe" @key @position(1)
end
declare Student extends Person
school : String @key @position(3)
end
declare LongTermStudent extends Student
years : int @key @position(5)
course : String @position(4)
end

I was following almost literally the example given in the "Drools
Introduction", Section 2.1.1.4., Type Declaration 'extends'.
It appears that Drools is very similar to
Eleusis<http://en.wikipedia.org/wiki/Eleusis_%28card_game%29>;-)

Hi,
from a user's point of view, who has been using Drools Expert in
production for years now, I'm wondering why there aren't *unit tests*
which are capable of answering this basic question in no time?
If test coverage is as low as it seems, can you recommend using Drools
Expert in production with a clear conscience?
Best regards
Ansgar
(the heretic ;-)
