[midPoint] Approver identified by role

[Fabio Contessi]

Hi,
I have a problem with the approver expression in midpoint 3.2, in the xml object "System Configuration".

I need to identify the approver by role assignment. So, I’m using this code snippet:

<approverExpression>
    <description></description>
    <script>
        <code>
            import com.evolveum.midpoint.prism.query.RefFilter
            import com.evolveum.midpoint.prism.PrismContext
            import com.evolveum.midpoint.prism.query.ObjectQuery
            import javax.xml.namespace.QName
            import com.evolveum.midpoint.prism.path.ItemPath
            import com.evolveum.midpoint.xml.ns._public.common.common_3.RoleType
            import com.evolveum.midpoint.xml.ns._public.common.common_3.UserType
          
            String[] names = ["Role-Approvatore-AD-XXX"]
            PrismContext prismContext = midpoint.createEmptyObject(UserType.class).asPrismObject().getPrismContext() 
            RefFilter filter = RefFilter.createReferenceEqual(UserType.F_ASSIGNMENT,UserType.class,prismContext,names)
            ObjectQuery query = ObjectQuery.createObjectQuery(filter)
            list = midpoint.searchObjects(UserType.class, query)
            for (def i = 0; i < list.size(); i++) {
                def oid = list.get(i).getOid()
                lOut.add(oid)
            }
            return lOut
        </code>
    </script>
</approverExpression>

but I get this error:

Error: com.evolveum.midpoint.util.exception.ExpressionEvaluationException: java.lang.ClassCastException: com.evolveum.midpoint.prism.PrismContainerDefinition cannot be cast to com.evolveum.midpoint.prism.PrismReferenceDefinition (new) approverExpression
2015-09-15 12:37:04,163 [MODEL] [Thread-57] ERROR (com.evolveum.midpoint.model.common.expression.Expression): Error evaluating expression in approverExpression: java.lang.ClassCastException: com.evolveum.midpoint.prism.PrismContainerDefinition cannot be cast to com.evolveum.midpoint.prism.PrismReferenceDefinition (new) approverExpression
com.evolveum.midpoint.util.exception.ExpressionEvaluationException: java.lang.ClassCastException: com.evolveum.midpoint.prism.PrismContainerDefinition cannot be cast to com.evolveum.midpoint.prism.PrismReferenceDefinition (new) approverExpression

Maybe I’m doing something wrong. Anyone could help me?

Thanks and regards.

  Fabio
