Default Sequential Mode Order in Decision Table
by bhavesh devashraye
As per the JBoss Project Documentation it is clear that if we set SEQUENTIAL = true then it will going to execute rules in Top to Down order but what if we make this flag false and even not set this field at all?
if SEQUENTIAL = false. Will it confirm Bottom to Top order of execution?
I have observed that if not set this SEQUENTIAL flag, by default rules get executed Bottom to Top order. Does this assumption is correct? Does JBoss always execute rules from Bottom to Top order if we not set this flag ( SEQUENTIAL ) ?

Validation in Guvnor fails due to unrecognized method of implemented interface
by Brody bach
Hi,
I have a class which implementes several interfaces
class MyClass implements interA, interB, interC {
private String nameA;
private String nameB;
private String ownString;
public String getNameA(){ ---impl of method from interface interA
return nameA;
}
public String getNameB(){ ---- impl method from interface interB
return nameB;
}
public String getOwnString{ ---- own method
return ownString;
}
}
Another class, MyBiggerClass has MyClass as its attribute:
class MyBiggerClass {
private MyClass myClass;
public MyClass getMyClass(){
return myClass;
}
}
In a rule, I use MyBiggerClass as follows:
$mybig : MyBiggerClass()
eval($mybig.getMyClass().getNameB().equals("HelloWorld"))
The evaluation fails, and it said
unable to resolve method using strict-mode: interA.getNameB()
As you can see, the validator checks as if the getNameB was a method of
interA (the first interface).
I'm wondering whether this is a bug, or do I have to somehow change the
structure of my class.
But the question is, why does it check the interfaces not the class itself?
Thanks for advices
Regard
bb

Comparing multiple accumulations
by Richard Sherman
First I'm new to drools and secondly where I'm working we're using version 4.0.7.
I have a list of accounts and each account contains a list of transactions. I wish to accumulate charge transactions and compare them to an accumulation of payment transactions for a given time period (such as the last month). And it gets slightly more awkward in that if a payment transaction is of a certain type it needs to be converted from a 4 weekly figure to a monthly figure ( using / 4 / 7 * 365 / 12). I've tried to use structures as follows but they are causing the then part of the rule never to fire.
rule "Account in arrears"
salience 10
no-loop
when
$acc : Account( // balance between £500 and £1000
accountBalanceInPence >= 50000 &&
accountBalanceInPence <= 100000
)
$s : MessageInfo( accountNumber == $acc.accountNumber )
Number($charges : intValue) from
accumulate(
(Transaction(
transactionDate > oneMonthAgo &&
amountInPence > 0 &&
$value : amountInPence)
from $acc.transactions),
sum($value)
)
Number($adjustment : intValue) from
accumulate(
(Transaction(
transactionDate > oneMonthAgo &&
amountInPence < 0 &&
transactionCode == "Type 1" &&
$value : amountInPence)
from $acc.transactions),
sum(($value / 4 / 7 * 365 / 12) - $value)
)
Number( intValue > ($charges + $adjustment)) from
accumulate(
(RentTransaction
(transactionDate > oneMonthAgo
$value : amountInPence)
from $acc.transactions),
sum($value)
)
then
$s.setMessage( "Account in arrears" );
update($s); // flag update
end
Thanks

classLoader issue...
by Jason Davidson
I'm getting this error message too. I'm running Drools 5.0.1 as a
bundle within an OSGi container. Like the parent post indicates it
worked with Drools 4.0.7 and it only happens when I put constraints on
fact fields.
Here's my stack:
