Relationship Classes and Map Service Queries

Question

How exactly are relationship classes/related data handled in a REST identify query?

In my case, each parcel in a feature class may be related to one or more records in a related survey table.  This layer is available as a map service. If I consume the map service in ArcGIS desktop, performing an identify query works exactly as I expect; I get all of the related survey records for a selected parcel.

When I perform an identify query in a Flex Client, I only get the attributes of the selected parcel, none of the related survey records are returned.

Is this a limitation of the REST query, or am I missing something here?

That functionality looks to be available in the Flex API 2.0.  How do I do this in 1.3?

This is expected behavior. MapService Identify and Find operations are not designed to return related records. To fetch related data, queryRelatedRecords operation should be used.
