I have a HAPI FHIR server with a Bundle resource provider with a createBundle method defined like this:

public MethodOutcome createBundle(@ResourceParam Bundle bundle,
                                       HttpServletRequest theRequest,
                                       HttpServletResponse theResponse)

To this server I am POST'ing a transaction Bundle specified according to Continua's profile H812.5. Inside this bundle the DeviceComponent resources have their logical id's specified like this:

        "resource": {
            "resourceType": "DeviceComponent",
            "id": "7EEDABEE34ADBEEF.C4B301D280C6",
            ....

This is according to H812.5 appendix A 3.1.2. However, when I traverse the Bundle resource inside the createBundle method all logical id's are null. Is this by choice or by accident?

To assign the id when creating a resource, you could use a HTTP PUT command.
http://build.fhir.org/http.html#update

Note that servers MAY choose to allow clients to PUT a resource to a location that does not yet exist on the server - effectively, allowing the client to define the id of the resource.

Otherwise, FHIR logical id's are assigned by the server.
http://build.fhir.org/resource.html#id

There was once some discussion about propagating id's (and resource versions) between servers, which may be of interest if you have a strong use case for that kind of thing.
