a nicer way would be
when
loanBO : LoanBO(la : loanAmount -> (la.getAmountDoubleValue () >
980.0) )
If I'm not mistaken this keeps the evaluation of the condition in the
alpha memory instead of the beta memory which basically means it is
evaluated when the object is asserted instead of when fireAllRules is
called. Somebody please correct me if this is incorrect.

Ok thanx everybody,
I used eval to solve my own problem
rule "test"
when
loanBO : LoanBO()
eval ( loanBO.getLoanAmount().getAmountDoubleValue() > 980.0 )
then
// anything
end
Thank you all.

When I tried this code snippet in a similar case
it gives me org.drools.rule.InvalidRulePackage: unknown:yy:xx
Unexpected token 'loanBO'
this is my Bean Classes
class LoabBO {
private Money loanAmount;
public Money getLoanAmount() {
return loanAmount;
}
void setLoanAmount(Money loanAmount) {
this.loanAmount = loanAmount;
}
}
class Money {
private final BigDecimal amount;
public double getAmountDoubleValue() {
return amount.doubleValue();
}
}
and this is my drl code
rule "test"
when
loanBO : LoanBO()
money : Money( amountDoubleValue > 980.0) from
loanBO.getLoanAmount()
then
// anything
end

Using 3.0.x version, Steven's suggestion is probably
the best. Using
the new version, you can use "from" as Geoffrey suggested.
Something
like that:
when
$p: Party()
$c: Contact() from p.getContacts()
$t : ContactType( name == "mobile" ) from
$c.getContactType()
then
//
end

This is also a textbook case of where 'from' should work,
from what
I've seen - although I don't think that's been released
yet. Someone
else could tell you more.

Hi Weily,
one way I think would work is
//explode party contracts
when
p : Party(c : contracts)
then
for(Iterator it = c.iterator();it.hasNext();) {
assert(it.next());
}
end
when
c : Contract(ct : contractType -> (ct.getName
().equals("mobile")))
p : Party(contracts contains c)
then
....

Here is such scenario.
First I create a party instance, which has a Set
attribute.
The set contains all avariable contact mechnism
for the party.
Here is the Bean class:
public class Party{
private Set contracts;
}
public class Contact {
private ContactType contactType;
private String contactValue;
}
public class ContactType {
private String name;
private String comments;
}
Now at rule, I want to select these Parties whose
contact type
support mobile phone..
Could you share such a sample ?
Thanks
Best Regards
Weily
