Hi,
Mark just told me there is a problem with MVEL calling functions... I believe he is working on that...

I still have the same problem :
* (1,6) unable to resolve method using strict-mode:
java.lang.Object.func(...)
* (1,6) unable to resolve method using strict-mode:
java.lang.Object.func(...)
package validity :false
org.drools.rule.InvalidRulePackage: Unable to build expression for
'consequence' '
drools.rule.dialect="java"
System.out.println(drools.getRule().getDialect());
System.out.println("ok"+func());
' : [Rule name=Your First Rule, agendaGroup=MAIN, salience=0, no-loop=false]
at org.drools.rule.Package.checkValidity(Package.java:416)
at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:292)
at mcmipih.rules.demo.service.TestDraft.main(TestDraft.java
:34)
my rule :
rule "Your First Rule"
dialect "mvel"
when
eval(true)
then
drools.rule.dialect="java"
System.out.println(drools.getRule().getDialect());
System.out.println("ok"+func());
end
