bug in DFS ? "E_METHOD_SHOULD_BE_OVERRIDDEN_INUrlContent"

GlenLantz

I have met the following problem using DFS (Developer Edition 6.6, .Net Productivity Layer)

1. Retrieved a Document (with Content) using IVersionControlService.GetCurrent()

     var res = versionControlService.GetCurrent(...)

2. called "res.DataObjects.First().Contents.First().CanGetAsByteArray()"

the following exception happened:

     System.Exception with message "E_METHOD_SHOULD_BE_OVERRIDDEN_INUrlContent"

what is it - a DFS bug? Or I misuse CanGetAsByteArray somehow> If I camm CanGetAsFile instead of the CanGetAsByteArray - everything is OK.
