testOccurrence.details not returned for all queries

Hi All,

I'm finding that for some requests the details field is not retured for test occurrences.  Any idea why the second cannot return the details field?

I'm trying to retrieve the results for all time a test of a given name has been run across builds.

Thanks,
Rob
