Hi, I try using globals in functions but I get un error, Exception in thread "main" org.drools.rule.InvalidRulePackage: Function Compilation error at org.drools.rule.Package.checkValidity(Unknown Source) at org.drools.common.AbstractRuleBase.addPackage(Unknown Source) at org.drools.examples.TroubleTicketExample.main(TroubleTicketExample.java:24) Example:.. package org.drools.examples import org.drools.examples.TroubleTicketExample.Customer; import org.drools.examples.TroubleTicketExample.Ticket; global java.util.Date mydate; ... function java.util.Date fmydate() { return mydate; } ... besides when I try to using in LHS, I get another error Escalate:Unable to return Declaration for identifier 'mydate' drools-examples/src/main/rules/org/drools/examples TroubleTicket.drl line 51 package org.drools.examples import org.drools.examples.TroubleTicketExample.Customer; import org.drools.examples.TroubleTicketExample.Ticket; global java.util.Date mydate; rule "Escalate" when customer : Customer( object == mydate ) and ticket : Ticket( customer == customer, status == "Escalate" ) then sendEscalationEmail( customer, ticket ); end So, I can use globlas only in RHS, ( then ...), this is true??? Greetings.
