Re: [rules-users] nested accessors with Sets

Edson, Thank you for the response. I tried writing the in-line eval as suggested but get this Exception: org.drools.rule.InvalidRulePackage: Unable to determine the used declarations : [Rule name=State, agendaGroup=MAIN, salience=0, no-loop=false] at org.drools.rule.Package.checkValidity(Package.java:408) at org.drools.common.AbstractRuleBase.addPackage( AbstractRuleBase.java:288) at [...] This is my rule: rule State dialect "mvel" when $ca:CandidateAssociation( eval ( ! nurseDetails.stateLicensures.contains( patientDetails.state ) ) ) then retract( $ca ); end I haven't yet but, plan to open an issue in JIRA as requested Thanks for your help.
