[rules-users] function call

[hypnosat7]

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
