in 4.0.1 "this" required in nested accessors?
by Manukyan, Sergey
Folks,
I Started using 4.0.1,
Regarding nested accessors, looks like they work, but they require to
put "this" at the beginning.
So rule
when
TestSupplier(testBusiness.statusActive == true) --> FAILS
When
TestSupplier(this.testBusiness.statusActive == true) --> OK!
It fails with the following exception:
org.drools.rule.InvalidRulePackage: Unable to determine the used
declarations : [Rule name=HQ To Active From Probation. Mfg On Probation
Exists., agendaGroup=MAIN, salience=10, no-loop=false]
at org.drools.rule.Package.checkValidity(Package.java:419)
Please confirm this to be a bug and then I will open JIRA for this, or
please let me know the reason behind this functionality,
Thanks,
-Sergey

A model class incompatibility issue causing most operations on BRMS fail
by Kunal Shah
I just started playing with BRMS (4.0.0 GA). After trying to upload one
particular model jar, my BRMS is almost inaccessible. Seems like all
calls (to open any rule assets/package) results in populating model info
and hence in following error:
Is there any way to remove this model jar file now and get back by other
configurations? I would think that this should be handled little
gracefully so that entire system doesn't become inaccessible. I am just
using default database configuration right now. I can start from scratch
again but if I have to do that, it will be bad.

Possible to check for null and empty string in same rule?
by Brian Enderle
One of the checks that we are required to do on our data is that the data is
not blank, meaning the value retrieved from the DB is not null and not ""
(empty string) or '' (empty characer), etc..
Is there anyway to create a DSL entry to do this check regardless of the data
type (Stirng, character, Date, etc.) that is returned?
I have tried the obvious ({field} == null || {field} == "") but this only
works for String types. I would really like to have just one DSL entry that
would handle all cases.
Thanks,
Brian Enderle

Hi...
currently the Drools reference manual is only available as HTML, is it
possible to also generate a PDF document from the documentation sources?
Kind regards

Execution problems with (or and (and
by vdelbart
Hi,
I have a problem with this execution :
rule "Your First Rule"
when
(or
not Venue()
(and v:Venue()
l:ListeSousVenue()
p:Param()))
then
System.out.println("OK - 1");
end
rule "Your Second Rule"
when
(or
not Venue()
(and p:Param()
l:ListeSousVenue()
v:Venue()))
then
System.out.println("OK - 2");
end
In my WM, I have a Param and a ListeSousVenue but no Venue
But after execution, I have just this result :
"OK - 1"
Why the second rule doesn't execute ?
Thanks,
Vdelbart

Ruleflow and Global ?
by vdelbart
Hello,
How to use global in my split condition of a Ruleflow ? :confused::confused:
I try this :
-----------------------------------------------------------------------------
My global map is a HashMap
when I write this :
Boolean(eval((Boolean)map.get("decision") == true)) from Boolean.TRUE;
I have this error :-( :
initPackage/Rule_RuleFlow_mcoProcess_31_32_0.java (10:386) : map cannot be
resolved
when I write this :
Boolean(booleanValue == false) from map.get("decision")
I have this error :-( :
Unable to build expression for 'from' node map.get("decision")' : [Rule
name=RuleFlow-mcoProcess-31-32, agendaGroup=MAIN, salience=0, no-loop=false]
