Need Javascript Assistance With Nashhorn

[Ullfig, Roberto Alfredo]

Hello, one of our scripts in attribute-resolver.xml stopped working due to the switch to Nashhorn engine in Java 8. There are docs I've read here:

https://wiki.shibboleth.net/confluence/display/SHIB2/IdPJava1.8

I've recoded it but the problem now is that the eduPersonAffiliation attribute keeps getting appended to with each successive access. So the first time the attribute is for example member;staff - the second time it's member;staff;member;staff etc... Here is the code, any ideas?

    <resolver:DataConnector xmlns="urn:mace:shibboleth:2.0:resolver:dc" xsi:type="dc:Static" id="eduPersonAffiliationCreate">
        <Attribute id="eduPersonAffiliation">
            <Value>dummy</Value>
        </Attribute>
    </resolver:DataConnector>

    <resolver:AttributeDefinition xmlns="urn:mace:shibboleth:2.0:resolver:ad" xsi:type="ad:Script" id="eduPersonAffiliation" >
        <resolver:Dependency ref="MySQL" />
        <resolver:Dependency ref="eduPersonAffiliationCreate" />
        <resolver:AttributeEncoder xsi:type="SAML1String" xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
            name="urn:mace:dir:attribute-def:eduPersonAffiliation" />
        <resolver:AttributeEncoder xsi:type="SAML2String" xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
            name="urn:oid:1.3.6.1.4.1.5923.1.1.1.1" friendlyName="eduPersonAffiliation" />
        <Script><![CDATA[
         eduPersonAffiliation.getValues().clear();
         for each ( affil in eduPersonAffiliationConcat.getValues().get(0).split(';') ) {
            eduPersonAffiliation.getValues().add(affil);
         }
        ]]></Script>
    </resolver:AttributeDefinition>
