Description

ObjectGraphBuilder currently resolves references in a sequential way, referenced nodes must be defined prior to being referenced by other nodes.
Example:

      def company = builder.company( name: 'ACME', employees: [] ) {
         address( line1: '123 Groovy Rd', zip: 12345, state: 'JV', id: 'a1' )
         employee(  name: 'Duke', employeeId: 1, id: 'e1' ) {
            address( a1 ) // or address( refId: 'a1' )
         }
      }

This improvement will allow the following case

      def company = builder.company( name: 'ACME', employees: [] ) {
         employee(  name: 'Duke', employeeId: 1, id: 'e1' ) {
            address( refId: 'a1' ) // note that refId must be a String!
         }
         address( line1: '123 Groovy Rd', zip: 12345, state: 'JV', id: 'a1' )
      }
