Hi,
I use drools 4.0.7 and I encounter a problem calling a function from a
rule written for mvel dialect.
The function I need to call has this signature :
function VOCounter createCounter(org.drools.spi.KnowledgeHelper
drools, String code, Number number)
When I call this function, I want to assign result to a variable, for
example to insert it to working memory later, or just to use it in
another function call.
So I wrote something like that (I am writing a DSL so part of the code is DSL ):
rule "CALCUL_RELICAT_CP"
salience 8
no-loop
when
not There is a counter called "RELICAT_CP"
There is a date called "startDate"
There is a date called "endDate"
There is a counter called "SOLDE_CP_CUM" with
- start date is last year
then
VOCounter $relicat =
createCounter(drools,"RELICAT_CP",$SOLDE_CP_CUM.value);
insert($relicat);
Copy counter $SOLDE_CP_CUM to SOLDE_RELICAT_CP
end
But I have the following stack trace :
org.drools.spi.ConsequenceException:
org.mvel.UnresolveablePropertyException: unable to resolve token:
createCounter(drools,"RELICAT_CP",$SOLDE_CP_CUM.value)

What is strange is that it works if I don't assign function call
result to a variable. For example the following works :
insert (createCounter(drools,"RELICAT_CP",$SOLDE_CP_CUM.value));
It also works if I assign $SOLDE_CP_CUM.value to a temporary variable
and use it for function call :
Number $val = $SOLDE_CP_CUM.value;
VOCounter $relicat = createCounter(drools,"RELICAT_CP",$val);
insert($relicat);
I had not this problem using java dialect. I understand nothing in
what happens ... Anyone has an idea what the problem is ?
Thanks in advance,
Olivier

Can you plz show us the DRL instead of the DSLR for your rule? use the
DRLViewer tab for that...

Thanks Edson. Here it is :
rule "CALCUL_RELICAT_CP"
salience 8
no-loop
when
not $RELICAT_CP : VOCounter (code=="RELICAT_CP")
$startDate : RuleDate(name=="startDate")
$endDate : RuleDate(name=="endDate")
$SOLDE_CP_CUM : VOCounter ( code=="SOLDE_CP_CUM",
startDate.year == ($startDate.year - 1) )
then
VOCounter $relicat = createCounter(drools,"RELICAT_CP",$SOLDE_CP_CUM.value);
insert($relicat);
insert(createCounter(drools,"SOLDE_RELICAT_CP",$SOLDE_CP_CUM.value));
end
I thought about trying with a newer version of mvel, but it doesn't
look so easy to upgrade it :(

9:38 a.m.
Well ... I found something very strange with Drools and mvel dialect
... It looks like Drools doesn't like points in function parameters !
I made this very simple test with a log function and the easier rule
you can have :
function void log (String message) {
System.out.println(message);
}
rule "test"
no-loop
when
eval(true)
then
log("hello world")
end
log("hello world") works ok
log("hello.world") (note the point) fails with this stack trace :
org.drools.spi.ConsequenceException:

It looks like there is a problem with point character, doesn't it ? Is
it a known problem ?

BTW, what version of MVEL are you using?
2008/12/15 Olivier THIERRY <olivier.thierry(a)gmail.com>
Well ... I found something very strange with Drools and mvel dialect
... It looks like Drools doesn't like points in function parameters !
I made this very simple test with a log function and the easier rule
you can have :
function void log (String message) {
System.out.println(message);
}
rule "test"
no-loop
when
eval(true)
then
log("hello world")
end
log("hello world") works ok
log("hello.world") (note the point) fails with this stack trace :
org.drools.spi.ConsequenceException:
org.mvel.UnresolveablePropertyException: unable to resolve token:

It looks like there is a problem with point character, doesn't it ? Is
it a known problem ?

I use mvel 1.3.9, so the latest 1.3.x version.
Is there a way to upgrade to mvel 2.x with drools 4.0.7 ? Or will I
have to wait for drools 5.0.0 ?

Sorry, I had not seen there was later version than 1.3.9.
Anyway, I tried with 1.3.12 and had the same problem.
From 1.3.13, it looks like there is a problem on mvel initialization
since I have this stack trace :

Nope, MVEL 2 is not backward compatible with the 1.3.x release.
I am talking with Mike about this.

Sorry, I had not seen there was later version than 1.3.9.
Anyway, I tried with 1.3.12 and had the same problem.
>From 1.3.13, it looks like there is a problem on mvel initialization
since I have this stack trace :
