Mark,

    Hmmm, something is going on with mvel integration... bellow must work.
    There are work arounds (like using plain java code, or using multiple patterns), but I think we need to fix that. Can you please include this info in the ticket.
   
    Thanks,

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.
Mark
